Image storage device for automobiles {STORAGE DEVICE OF AN IMAGE FOR A CAR}
[8] The present invention relates to a video storage device for a vehicle. More specifically, the video signal of a camera mounted at the rear of a vehicle is transmitted to the display unit of the AV system and outputted. The data is transmitted to the storage system, compressed according to the MPEG standard, and stored in the storage medium. The data can be repeatedly reproduced regardless of the location.
[9] In general, various mirrors, that is, side mirrors and rear mirrors, are installed and used for the driver to recognize a surrounding situation inside or outside of a vehicle.
[10] In addition, recently, by installing a collision sensor, a proximity sensor, a camera, etc. in the front and rear of the car, the collision sensor to detect the collision state by the collision sensor during driving and parking, or by detecting a vehicle approaching through the proximity sensor to alert The driver's safety is prevented from collision or collision and theft prevention is prevented in advance.
[11] In addition, the camera is mainly mounted on the rear of the vehicle so that the driver can conveniently back up while watching the rear situation as well as monitoring the vehicle coming from the rear.
[12] At this time, the video signal of the camera can be seen by the passengers through the monitor or the display unit of the audio-video system in the car.
[13] However, the above-described apparatus has a problem in that it is not possible to reproduce the necessary screen because the passenger is only able to see the displayed screen while driving.
[14] Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to provide a separate storage system in addition to the device for outputting the image signal taken by the rear of the vehicle by the display unit of the AV system According to the passenger's selection, that is, the on / off of the selection switch, the image signal photographed by the camera is to be stored.
[1] 1 is a block diagram showing the configuration of a video storage device for a vehicle according to the present invention.

[15] In the present invention for achieving the above object, in the vehicle image storage device for viewing the image taken by the camera mounted on the rear of the vehicle in the vehicle,
[16] An AV system for outputting a signal transmitted from the camera through a display unit; It provides a vehicle image storage device comprising a storage system for receiving and storing the signal transmitted from the camera.
[17] In the present invention, the storage system includes an input unit for receiving a signal from the camera; An A / D converter for converting an analog signal received through the input into digital; An MPEG encoder for encoding the digital signal passing through the A / D converter unit to MPEG standard; It is preferably composed of a storage unit for storing the data compressed through the MPEG encoder.
[18] In addition, in the present invention, it is preferable that the selection switch for transmitting or blocking the video signal of the camera to the input unit of the storage system is provided, the memory card is used as the storage medium of the storage unit.
[19] Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
[20] In addition, the present embodiment is not intended to limit the scope of the present invention but is merely presented as an example, and there may be various embodiments implemented through the technical idea.
[21] 1 is a block diagram showing the configuration of an image storage device for a vehicle according to the present invention.
[22] As shown, the image storage device for a vehicle according to the present invention can not only view a video signal of a camera mounted at the rear of a vehicle through a display unit of an AV system, but also store an image output according to a selection. It is done.
[23] Looking at the present invention in detail, the camera 11 is mounted on the rear of the vehicle, the video signal of the camera 11 is output through the display unit 22 of the AV system 21 is a situation that the occupant takes place in the rear can see.
[24] In addition, the signal transmitted from the camera 11 is transmitted to and stored in the storage system 31, the storage system 31 is the input unit 32 for receiving the signal of the camera 11 and the input unit 32 An A / D converter unit 33 for converting an analog signal input through the digital signal, an MPEG encoder 34 for encoding a digital signal passed through the A / D converter unit 33 to an MPEG standard, and the MPEG encoder It consists of a storage unit 35 for storing the compressed data through.
[25] At this time, a storage card of the storage unit 35 is a memory card that can be used conveniently and conveniently.
[26] On the other hand, it is effective that the user selectable switch 38 is provided so that the image signal of the camera 11 is transmitted or blocked to the input unit 32 of the storage system 31.
[27] The operation and effects of the image storage device for a vehicle having the above structure are as follows.
[28] When the camera 11 mounted at the rear of the vehicle sends an image signal, the display unit 22 of the AV system 21 mounted at the interior of the vehicle outputs the image signal so that the passenger can see the situation occurring at the rear.
[29] On the other hand, the occupant can selectively store images of the rear of the vehicle, when the selection switch 38 is turned on, the image signal is transmitted to the storage system 31 and stored as data, and the selection switch 38 When off, the video signal is not transmitted to the storage system 31 and is not stored as data.
[30] Therefore, when the occupant turns the selection switch 38 on, the video signal (analog signal) of the camera 11 is transmitted to the input unit 32.
[31] The signal transmitted to the input unit 32 is transmitted to the A / D converter 33, which converts an analog image signal into a digital signal.
[32] The digitally changed video signal is transmitted to the MPEG encoder 34, and the MPEG encoder 34 encodes the digital signal in a moving picture experts group (mpeg) format.
[33] The data compressed through the above encoding process is stored in the storage unit 35 so that the user can play back the captured content any time the user needs. The storage medium used as the storage unit 35 is a portable hard As a memory card (or memory stick), a medium that is easy to move and has a high storage capacity is used.
[34] In particular, the mobile storage medium allows the user to easily reproduce the photographed contents through an output medium such as a computer not only in the vehicle but also at home or in another place.
[35] As described above, according to the video storage device for an automobile according to the present invention, the video signal of the camera is transmitted not only to the AV system but also to the storage system, so that the required video signal can be stored.
[36] In particular, the selection switch is provided to block or transmit the video signal to the storage system, thereby advantageously storing only the necessary video.
