<P>PROBLEM TO BE SOLVED: To provide an image output device capable of achieving the simultaneous output function of image data for two screens (two systems) without increasing the number of output pins. <P>SOLUTION: The output timing generation part 102 of a multiplex data generation part 100 provided in the image output device fetches video data A and B according to one side edge of timing clocks A and B as before. A selector 101 supplies the instruction of outputting them at both edges of the clocks, that is outputting the video data A at a rising edge and the video data B at a falling edge, to the output timing generation part 102. As a result, multiplex data for which the video data A and B are alternately arranged are generated, and it becomes possible to simultaneously output the video data A for a video encoder for fetching the image data at the rising edge of the clock and the video data B for a video encoder for fetching the image data at the falling edge of the clock by an interface for one screen. <P>COPYRIGHT: (C)2007,JPO&INPIT |
