VIDEO PROCESSING SYSTEM
First Claim
1. A video processing system comprising:
- N (N is an integer of two or more) image processors each configured to be capable of processing high definition (HD)-size video and be synchronous with an HD synchronization signal;
a region division calculator configured to control data transfer regions of the N image processors; and
an image processing mode controller configured to control image processing modes of the N image processors,whereinthe N image processors process N respective pieces of sub-video data obtained by dividing video data, and the processed N pieces of sub-video data are combined in a succeeding stage from the N image processors.

Abstract
In a video processing system which divides HD-size image data into a plurality pieces of sub-image data and performs image processing for upconversion to 4K×2K image data, four image processors synchronous with an HD signal each process a corresponding one of the four pieces of sub-image data. In this case, the image processors process the four pieces of sub-image regions while causing the four pieces of sub-image regions to overlap at their division boundaries, and particularly process the overlapping regions during respective blanking periods. After the image processing of the image processors, the overlapping data is removed. Thereafter, the pieces of image data of the four sub-regions are combined. Therefore, the division boundaries of the pieces of sub-images can be processed without a degradation in image quality.
