    [14] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic picture frame module and a method thereof, and more particularly, to an electronic picture frame module and a method for realizing an electronic picture frame function by modularizing only an electronic picture frame function and applying the same to a display device.
    [15] In general, an electronic picture frame (album) or a digital picture frame is a digital picture such as an LCD by reading image data processed by a digital camera, or image data stored in a personal computer, in place of a frame in which a conventional picture or picture is placed. By displaying the image without any difference in the resolution of the display device, it is a device that can function as a picture frame or album by showing various images instead of showing only one fixed image.
    [16] The conventional electronic picture frame or digital picture frame may be photographed with a digital camera or scanned with a scanner using a scanner, and image data compressed with a codec or the like may be stored as a file in a memory of a digital camera or a personal computer. A method of loading and displaying the file into the electronic frame or digital frame is used.

    [20] The main control unit 102 is input through the function keys included in the keypad 101 based on a control program (eg, a Picture-Source environment) for constructing an operating system of the electronic picture frame. According to the control signal, the respective components are collectively controlled organically.
    [21] The recording medium controller 103 is for reading image data recorded on the image recording medium 112 or recording image data on the image recording medium 112 according to the control signal of the main controller 102. .

    [24] The image display unit 106 is for receiving the menu character data and the image data decompressed from the codec 104 according to the control signal of the OSD controller 105 to display the characters and images on the screen. The image display section 106 is composed of a Liquid Crystal Display (LCD).
    [25] The image display controller 107 is for driving the image display unit 106 in accordance with a control signal of the OSD controller 105.
