IMAGE PROCESSING DEVICE, IMAGE DISPLAY DEVICE AND IMAGE PROCESSING METHOD |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide an image processing device capable of smoothly switching a display by the change in a frame frequency while reducing a load of software processing. <P>SOLUTION: A video processing device 100 for generating a vertical synchronizing signal VSYNCo in response to a video signal VIDEOo comprises a vertical synchronizing signal detection circuit 140 for detecting a vertical synchronizing signal VSYNCi during the detection period of the vertical synchronizing signal VSYNCi in response to the video signal VIDEOo and a vertical synchronizing signal output circuit 150 for outputting the vertical synchronizing signal VSYNCo in response to the vertical synchronizing signal VSYNCi when the vertical synchronizing signal VSYNCi is detected by the vertical synchronizing signal detection circuit 140 during the above detection period. <P>COPYRIGHT: (C)2012,JPO&INPIT |
