ABSTRACT:
In a moving picture decoding display apparatus and moving picture decoding display method according to the present invention, moving picture decoder101decodes a moving picture signal, RGB matrix manipulation section103converts the decoded video signal in YCbCr format into a video signal in RGB format, contrast/brightness adjusting section104adjusts the contrast and brightness of the video signal in RGB format, and liquid crystal display module section110displays the adjusted video signal on liquid crystal panel109. At this point, operation control section105switches on and off the operation of RGB matrix manipulation section103and contrast/brightness adjusting section104corresponding to the actual frame rate in moving picture decoder101, and only when the operation is “on”, the section105controls so that the video signal from contrast/brightness adjusting section104is stored in video RAM107in liquid crystal display module section110. Thus, since the operation of required video signal processing is switched on and off based on the actual frame rate, it is possible to suppress the power consumption in the entire apparatus.
