    Module for capturing a three-dimensional image and method for capturing a three-dimensional image
    The present invention relates to an image capture module and an image capture method, in particular to a module for capturing a three-dimensional image and a method for capturing a three-dimensional image.
    Lens modules for image acquisition are known from the prior art, which can comprise a light-conducting and translucent optical component group, the light passing through the optical component group being received by an image sensor and converted into an image signal. In the course of the development of image acquisition technology, the technology for capturing three-dimensional images is increasingly coming to the fore.
    One of the methods for capturing three-dimensional images is the anaglyph technique (anaglyph), which allows individual encoding of the two eyes of an observer with the aid of various filters in order to achieve a three-dimensional visual effect. Specifically, an anaglyph image contains two images generated with the aid of light filtered by various filter elements, the processing of which results in a three-dimensional image that can be observed by an observer. For the observer this is too
    BE2019 / 0030 justify that the visual cortex in the human brain combines the two images in a three-dimensional image.
    In the prior art, however, two lenses have to be used in order to obtain two images generated with the aid of light filtered by different filter elements. In particular, it is usually necessary to insert a first filter element, e.g. a green filter element, a lens for a first image and a second filter element, e.g. a red filter element, lens to use for a second image. Finally, the two images are subjected to image processing. However, such a structural design proves to be disadvantageous for today's various micro-miniaturized electronic products. For example, large-volume lens designs are not suitable for portable electronic devices, such as mobile phones, tablet PCs and smart watches, which have a limited volume. In this respect, there is still scope for improvement in the previously known modules for capturing three-dimensional images.
    Based on the disadvantages of the prior art, it is an object of the present invention to provide a module for capturing a three-dimensional image and a method for capturing a three-dimensional image, in which different images generated by different spectra are captured using a single objective
    BE2019 / 0030 can reduce the volume of the product using this image capture module and reduce manufacturing costs.
    According to the invention, the object is achieved by a module for capturing a three-dimensional image, which comprises an optical component arrangement, a filter element, an image sensor unit and an image processing unit. Here, the optical component arrangement and the filter element are located on the same side of the image sensor unit, while the image processing unit is electrically connected to the image sensor unit. The filter element comprises a substrate and a cover layer arranged on the substrate, the cover layer comprising a first light transmission section and a second light transmission section. In this case, a first light beam having a first spectrum passes through the first light transmission section and is received by the image sensor unit, so that the image sensor unit receives a first image signal. On the other hand, a second light beam having a second spectrum passes through the second light transmission section and is received by the image sensor unit, so that the image sensor unit receives a second image signal, the first spectrum and the second spectrum differing from one another. The first image signal and the second image signal are processed by the image processing unit into three-dimensional image information.
    BE2019 / 0030
    According to the invention, the object is further achieved by a method for acquiring a three-dimensional image, which comprises the following: passing a first light beam having a first spectrum and a second light beam having a second spectrum through a filter element, the filter element a substrate and a cover layer arranged on the substrate comprising a first light transmission section and a second light transmission section, the first light beam passing through the first light transmission section and the second light beam passing through the second light transmission section, the first spectrum and the second spectrum being different from one another; optically processing at least one of the first light beam and the second light beam with the aid of an optical component arrangement;
    Receiving the first light beam passing through the first light transmission section and the second light beam passing through the second light transmission section from an image sensor unit, so that the image sensor unit receives a first image signal and a second image signal; and generating three-dimensional image information by image processing of the first image signal and the second image signal with the aid of an image processing unit.
    With the module according to the invention for capturing a three-dimensional image and the method according to the invention for capturing a three-dimensional image, the embodiment advantageously enables a first light beam having a first spectrum
    BE2019 / 0030 passes through the first light transmission section and is received by the image sensor unit, so that the image sensor unit receives a first image signal, while a second spectrum having a second spectrum passes through the second light transmission section and is received by the image sensor unit, so that the image sensor unit receives a second one Receives image signal, the first spectrum and the second spectrum differing from one another, and by the configuration such that the first light beam passes through the first light transmission section and the second light beam passes through the second light transmission section, the first spectrum and the second spectrum differing from one another, and that the first light beam passing through the first light transmission section and the second light beam passing through the second light transmission section are received by an image sensor unit, so that the image sensor unit receives a first image signal and a second image signal, an improvement of the module for capturing a three-dimensional image in terms of its structure, its volume and its production costs can be achieved.
    For a better understanding of the features and technical configurations of the invention, this will be described in more detail below with the aid of the attached figures. The accompanying drawings do not represent any restriction of the invention, but only serve to explain the invention.

    The embodiments of a module according to the invention for capturing a three-dimensional image and a method according to the invention for capturing a three-dimensional image are described below on the basis of specific specific exemplary embodiments. It will be apparent to those skilled in the art that advantages and technical effects of the invention can be derived from the disclosures in the present description. The invention can be embodied or used in other specific exemplary embodiments, with various modifications or changes being able to be made to the details disclosed in the present description depending on requirements and application, without leaving the basic ideas of the invention. Furthermore, it should be noted that the individual components of the invention are not shown in their actual size, but only schematically. The following embodiments serve to explain the embodiments of the invention in more detail and in no way limit the scope of protection of the invention.
    It goes without saying that the terms “first,” second, “third, etc., which may be used to describe various elements or signals, should not be interpreted as restrictive. Rather, such terms serve primarily to distinguish one element from another or a signal from another. Of

    Furthermore, the term used in the present description can include “or possibly each of the items listed in each case or a combination of several of the items listed in each case.
    1 shows a module for capturing a three-dimensional image M according to an exemplary embodiment of the invention, which module comprises an optical component arrangement 1, a filter element 2, an image sensor unit 3 and an image processing unit 4. Here, the optical component arrangement 1 and the filter element 2 are located on the same side of the image sensor unit 3, while the image processing unit 4 is electrically connected to the image sensor unit 3. In the exemplary embodiments of the invention, the optical component arrangement 1, the filter element 2 and the image sensor unit 3 can be arranged as shown in FIG. the filter element 2 is located between the optical component arrangement 1 and the image sensor unit 3. Alternatively, it is also conceivable that the optical component arrangement 1 is located between the filter element 2 and the image sensor unit 3. In other words, the optical component arrangement 1 and the filter element 2 can be arranged in any order according to the invention.
    The optical component arrangement 1 used in the exemplary embodiments of the invention can comprise a plurality of optical components or lenses.
    BE2019 / 0030
    For example, the optical component arrangement 1 can function in a light-collecting or light-guiding manner. Within the scope of the invention, the optical components or lenses comprised by the optical component arrangement 1 are not subject to any restrictions with regard to their types and numbers and can be set and selected as required. Light can pass through the optical component arrangement 1 and be received by the image sensor unit 3 located on one side of the optical component arrangement 1.
    1 and 2 show, the filter element 2 according to the exemplary embodiment of the invention is designed to be transparent to light having a specific spectrum in order to achieve a light-filtering effect. In detail, the translucent surface of the filter element 2 is divided or subdivided into sections which are permeable to different spectra and have different types of light. The filter element 2 can comprise a substrate 21 and a cover layer 22 arranged on the substrate 21.
    The substrate 21 of the filter element 2 can be a glass substrate with a thickness of 0.01 to 0.05 mm. In fact, the module for acquiring a three-dimensional image M according to the exemplary embodiment of the invention must be kept small in terms of its volume in order to be able to be used in microminiaturized electronic devices. When designing the structure of the filter element 2, glass substrates with a small thickness are therefore preferred as the substrate 21
    BE2019 / 0030 the respective product comprising the module for capturing a three-dimensional image M is light and handy and easy to bring along.
    The cover layer 22 located on the substrate 21 can be produced on the substrate 21 using any known coating method. For example, a material are deposited on the substrate 21 by means of chemical vapor deposition in order to produce the cover layer 22. In the exemplary embodiments of the invention, the light-transmissive surface of the filter element 2, as mentioned above, is divided or subdivided into sections which are transmissive for different spectra and have different types of light. This means that the cover layer 22 can comprise a first light transmission section 22a and a second light transmission section 22b.
    According to the invention, the number of light transmission sections covered by the cover layer 22 of the filter element 2 are in fact not restricted, insofar as the desired effect can be achieved with the filter element 2, i.e. light having different spectra is transmitted in order to be able to acquire a three-dimensional image. For example, the cover layer 22 of the filter element 2 can comprise two, three or more than four non-overlapping light transmission sections.
    BE2019 / 0030
    II
    2 and 3 are referred to at the same time.
    In the embodiment shown in FIG. 2, the cover layer 22 of the filter element 2 comprises two non-overlapping light transmission sections, namely the first light transmission section 22a and the second light transmission section 22b. In addition, the first light transmission section 22a and the second light transmission section 22b each form a continuous section and each occupy approximately one half of the surface of the cover layer 22.
    In the embodiment according to FIG. 3, the cover layer 22 of the filter element 2 likewise comprises a first light transmission section 22a and a second light transmission section 22b. In contrast to the embodiment according to FIG. 2, the first light transmission section 22a in the embodiment according to FIG. 3 comprises a plurality of discontinuous light transmission sub-sections (not designated), the second light transmission section 22b also comprising a plurality of discontinuous light transmission sub-sections (not designated). In other words, in the exemplary embodiments of the invention, the first light transmission section 22a and the second light transmission section 22b can also be arranged alternately.
    In addition, the filter element 2 is not limited to the rectangular shape shown in FIGS. 2 and 3. Rather, the filter element 2 can have a circular shape or another shape, for example.
    BE2019 / 0030
    Subsequently, reference is made again to FIGS. 1 and 2. As shown by way of example in the embodiment according to FIG. 2, the first light transmission section 22a is transparent to a first light beam LI having a first spectrum and the second light transmission section 22b is transparent to a second light beam L2 having a second spectrum, the one through the first light transmission section 22a the first light beam LI passing through and the second light beam L2 passing through the second light passage section 22b can be received by the image sensor unit 3, so that the image sensor unit 3 receives a first image signal S1 and a second image signal S2.
    In other words, in an image acquisition process, the light L originating from an object 0 (for example reflected on the object 0), as can be seen in FIG. 1, can have light spectra having different spectra, such as a first light beam LI having a first spectrum and a second one Spectrum comprising second light beam L2, wherein both the first light beam LI and the second light beam L2 pass through the optical component arrangement 1 and the filter element 2 and are received by the image sensor unit 3.
    Specifically, the first light beam LI having the first spectrum passes through the first light passage section 22a and is emitted by the image sensor unit 3
    BE2019 / 0030 received so that the image sensor unit 3 receives a first image signal S1. On the other hand, the second light beam L2 having the second spectrum passes through the second light passage section 22b and is received by the image sensor unit 3, so that the image sensor unit 3 receives a second image signal S2.
    The image sensor unit 3 can comprise a charge-coupled device (CCD) or a complementary metal oxide semiconductor (CMOS).
    According to the invention, however, the image sensor unit 3 is not restricted in terms of its type.
    It should be noted that the first spectrum and the second spectrum differ from each other. The first spectrum is e.g. around a blue light spectrum and in the second spectrum e.g. around a red light spectrum. Indeed, the first spectrum and the second spectrum may have substantially chromatically opposite colors, such as red and cyan. A stereoscopic image can be generated by using two spectra of such chromatically opposite colors. For example, the first light beam L1 can be a red light beam and the second light beam L2 can be a blue light beam.
    Moreover, the first light transmission portion 22a may be made of a first light-transmissive material and the second light transmission portion 22b may be made of one of the first
    BE2019 / 0030 translucent material consist of various second translucent material. Here, the first translucent material and the second translucent material can be, for example, silicon dioxide (SiO 2 ), titanium dioxide (TiO 2 ) or a laminated material consisting thereof. For example, the cover layer 22 of the filter element 2 can be a coating formed by alternating coating with silicon dioxide and titanium dioxide.
    As mentioned above, the first light beam L1 has a first spectrum and the second light beam L2 has a second spectrum that is different from the first spectrum. In one embodiment of the invention, the first light beam L1 can comprise a first light having a single frequency or more than two different frequencies, while the second light beam L2 comprises a second light having a single frequency or more than two different frequencies. In fact, the first light beam L1 and the second light beam L2 have different wavelength ranges. In other words, the first light beam L1 and the second light beam L2 can contain light having different wavelength ranges.
    As can also be seen in FIG. 1, the first light beam L 1 and the second light beam L 2 pass through different sections of the cover layer 22 of the filter element 2 and are received by the image sensor unit 3. The image sensor unit 3 can receive the received first light beam L1 and second
    BE2019 / 0030
    Convert light beam L2 into a first image signal S1 or a second image signal S2 and transmit the first image signal S1 and the second image signal S2 to the image processing unit 4 for image processing.
    In the exemplary embodiments of the invention, the first image signal S1 and the second image signal S2 are processed by the image processing unit 4 into three-dimensional image information. The image processing unit 4 can have a processor (image processing), e.g. a microprocessor. According to the invention there is no restriction of the image processing unit 4 with regard to its type.
    As mentioned above, the first light beam LI passing through the filter element 2 after being received by the image sensor unit 3 is converted into a first image signal S1 (ie, first image recording), while the second light beam L2 passing through the filter element 2 is received by the image sensor unit 3 is converted into a second image signal S2 (ie second image acquisition). Thereafter, the image processing unit 4 can combine this image signal group (including the first image signal S1 and the second image signal S2) by the anaglyph technique (anaglyph), which is known as a 3D coding method, so that a three-dimensional effect arises, i.e. summarize in a three-dimensional image.
    BE2019 / 0030
    In accordance with the module for capturing a three-dimensional image M described above, the exemplary embodiment of the invention also provides a method for capturing a three-dimensional image, the flowchart of which is shown in FIG. 7.
    It can be seen from FIG. 7 that first a first light beam L1 having a first spectrum and a second light beam L2 having a second spectrum pass through the filter element 2 (step S100). As mentioned above, the filter element 2 comprises a substrate 21 and a cover layer 22 arranged on the substrate 21. The cover layer 22 comprises a first light transmission section 22a and a second light transmission section 22b, the first light beam L1 through the first light transmission section 22a and the second light beam L2 passes through the second light passage portion 22b. The first spectrum and the second spectrum differ from each other.
    In step S100, filtering of light spectra with different spectra is carried out with the aid of a specially designed filter element 2, i.e. a filter element 2 having a first light transmission section 22a and a second light transmission section 22b (a cover layer 22) is provided at different times in order to be able to obtain different image recordings (different image signals) later.
    BE2019 / 0030
    Furthermore, the method for capturing a three-dimensional image can include optically processing at least one of the first light beam LI and the second light beam L2 with the aid of an optical component arrangement 1 (step S102). It should be noted that in the method for capturing a three-dimensional image according to the exemplary embodiment of the invention, steps S100 and S102 do not necessarily have to be carried out in the order proposed here. For example, the first light beam L 1 and the second light beam L 2 are shown in FIG. 1
    Embodiment first subjected to optical processing (e.g. focusing) by means of the optical component arrangement 1 and then pass through the filter element 2.
    This is followed by the reception of the first light beam L1 passing through the first light passage section 22a and the second light beam L2 passing through the second light passage section 22b from the image sensor unit 3, so that the image sensor unit 3 receives a first image signal S1 and a second image signal S2 (step S104 ). Since in the module for capturing a three-dimensional image M according to the exemplary embodiment of the invention, the first light beam L1 and the second light beam L2 are received by the image sensor unit 3 only after they have passed through the optical component arrangement 1 and the filter element 2, step S104 is carried out after Step S100 and step S102 are carried out.
    BE2019 / 0030
    Finally, the method for acquiring a three-dimensional image further comprises generating three-dimensional image information by image processing the first image signal S1 and the second image signal S2 with the aid of an image processing unit 4 (step S106). As mentioned above, the image processing unit 4 can take the form e.g. of a microprocessor by the anaglyph technique (anaglyph) combine the first image signal S1 and the second image signal S2 so that a three-dimensional effect arises, i.e. summarize in a three-dimensional image.
    The details of the module for capturing a three-dimensional image M and the method for capturing a three-dimensional image according to the embodiment of the invention will be discussed in more detail below with the aid of various exemplary embodiments of the invention.
    First embodiment
    Reference is made to FIG. 4, which shows a schematic representation of the signal transmission in a module for capturing a three-dimensional image M according to a first exemplary embodiment of the invention.
    The module for capturing a three-dimensional image M according to the exemplary embodiment of the invention additionally comprises a lighting unit 5 which can be electrically connected to the image processing unit 4. In addition, the lighting unit 5 can be any one for
    BE2019 / 0030
    Known lighting element suitable for capturing a three-dimensional image. For example, the lighting unit 5 can comprise a light-emitting diode (LED). In one embodiment of the invention, the lighting unit 5 comprises at least two light-emitting diodes which can emit original light beams having different spectra. The two light-emitting diodes can be controlled so that they each emit a light beam at a predetermined point in time. For example, the lighting unit 5 comprises a red LED and a blue LED in order to emit a first original light beam 0L1 (red light beam) and a second original light beam 0L2 (blue light beam).
    The first original light beam 0L1 and second original light beam OL2 generated by the lighting unit 5 are reflected on an object 0 to be observed, so that a first light beam L1 and a second light beam L2 are formed, which pass through the filter element 2 at different times. In other words, in the first exemplary embodiment of the invention, the lighting unit 5 emits at least two original light beams (the first original light beam OL1 and the second original light beam OL2) that have different spectra and are reflected on the object 0 to be observed in such a way that one has a first spectrum first light beam L1 and a second light beam L2 having a second spectrum are produced.
    BE2019 / 0030
    Therefore, the first light beam LI and second light beam L2 arising at different times pass through the filter element 2 at different times and are received by the image sensor unit 3 to generate a first image signal S1 and a second image signal S2, which are combined by the image processing unit 4 three-dimensional image can be processed.
    In accordance with the development of the structural design of the module for capturing a three-dimensional image M, the method for capturing a three-dimensional image in the first exemplary embodiment of the invention furthermore comprises generating a first original light beam OL1 and a second original light beam OL2 with the aid of a lighting unit 5, the first original light beam OL1 and the second original light beam OL2 are reflected on an object to be observed 0, so that a first light beam LI and a second light beam L2 arise which pass through the filter element 2 at different times.
    Second embodiment
    5 and 6, FIG. 5 shows a functional block diagram of a module for capturing a three-dimensional image M according to a second exemplary embodiment of the invention, and FIG. 6 shows the signal transmission in the module for capturing a
    BE2019 / 0030 three-dimensional image according to the second embodiment of the invention.
    A comparison of FIG. 6 with FIG. 4 shows that the difference between the second and the first exemplary embodiment inter alia. in the source of the light rays (light source). In addition, the module for capturing a three-dimensional image M according to the second exemplary embodiment, as shown in FIG. 5, additionally comprises a switching and control unit 6 and a cover element 7.
    In the second exemplary embodiment, the first light beam L1 and the second light beam L2 arise in that a mixed light ML is reflected on an object 0 to be observed. Compared to the first exemplary embodiment, in which original light beams (a first original light beam OL1 and a second original light beam OL2) having different properties (for example different spectra) are emitted at different times, in the second exemplary embodiment a mixed light ML with at least a first original light beam and a second original light beam used as a light source. In the module for capturing a three-dimensional image M according to the second exemplary embodiment, for example the ambient light, such as sunlight, can be used as the light source without having to provide an additional lighting unit 5.
    BE2019 / 0030
    In order to do justice to the changed light source, the module for capturing a three-dimensional image M according to the second exemplary embodiment, as mentioned above, additionally comprises a switching and control unit 6 and a cover element 7, the switching and control unit 6 being electrically connected to the cover element 7 connected is. Furthermore, the cover element 7 interacts with the filter element 2. Depending on the switching and control unit 6, the covering element 7 can e.g. cover a part of the filter element 2 to control the types of light rays passing through the filter element 2 at different times.
    For example, the cover element 7 is controlled at different times by the switching and control unit 6 in such a way that it covers the first light transmission section 22a or the second light transmission section 22b, so that the mixed light ML has at least one first original light beam and one second original light beam on it observing object 0 is reflected such that a first light beam L1 and a second light beam L2 are formed. The first light beam L1 and the second light beam L2 pass through the filter element 2 at different times.
    In one embodiment, after the mixed light ML has been reflected on the object 0 to be observed, a reflected light is produced which comprises a first light beam L1 and a second light beam L2. It deals
    BE2019 / 0030 with the first light beam LI e.g. around a red light beam and for the second light beam e.g. around a blue beam of light. In addition, the first light transmission section 22a of the cover layer 22 of the filter element 2 is transparent to the red light beam, but not to the blue light beam. In contrast, the second light transmission section 22b of the cover layer 22 of the filter element 2 is transparent to the blue light beam, but not to the red light beam.
    At a first point in time, the cover element 7 is controlled by the switching and control unit 6 in such a way that it covers the first light transmission section 22a of the cover layer 22 of the filter element 2. This leads to the fact that the first light beam LI contained in the reflected light resulting from the reflection of the mixed light ML on the object 0 to be observed is partly blocked by the cover element 7 and partly by the second light passage section 22b. At the same time, part of the second light beam L2 passes through the second light passage portion 22b and is received by the image sensor unit 3. Therefore, the image sensor unit 3 only receives the second light beam L2 at the first time. In other words, the image sensor unit 3 does not receive a red light signal at the first point in time, but only a blue light signal. The image sensor unit 3 then converts the second light beam L2 into a second image signal S2 and transmits this to the image processing unit 4.
    BE2019 / 0030
    The cover element 7 is then controlled at a second point in time by the switching and control unit 6 in such a way that it covers the second light transmission section 22b of the cover layer 22 of the filter element 2. This leads to the fact that the second light beam L2 contained in the reflected light resulting from the reflection of the mixed light ML on the object to be observed 0 is blocked partly by the cover element 7 and partly by the first light passage section 22a. At the same time, part of the first light beam L 1 passes through the first light transmission section 22 a and is received by the image sensor unit 3. Therefore, the image sensor unit 3 only receives the first light beam L1 at the second point in time. In other words, the image sensor unit 3 does not receive a blue light signal at the second point in time, but only a red light signal. The image sensor unit 3 then converts the first light beam L1 into a first image signal S1 and transmits this to the image processing unit 4.
    After the image processing unit 4 has received the first image signal S1 provided by the first light beam L1 (red light beam) and the second image signal S2 provided by the second light beam L2 (blue light beam), the first image signal S1 and the second image signal S2 can be processed using image processing combine with each other to create a three-dimensional image.
    BE2019 / 0030
    In accordance with the development of the structural design of the module for capturing a three-dimensional image M, the method for capturing a three-dimensional image in the second exemplary embodiment of the invention further comprises controlling a cover element 7 with the aid of a switching and control unit 6 such that the cover element 7 is different Times covers the first light transmission section 22a or the second light transmission section 22b, so that the mixed light ML is reflected at least with a first original light beam and a second original light beam on an object to be observed 0 in such a way that a first light beam LI and a second light beam L2 arise, wherein the first light beam L1 and the second light beam L2 pass through the filter element 2 at different times.
    Advantageous effects of the exemplary embodiments
