Digital video image frequency detecting method for e.g. digital set top box, involves dividing current frame into region based on determined phase value by statistics and segmentation unit and assigning region movement phase value to region

摘要

The method involves assigning a pixel movement phase value to a pixel of a current frame of digital video images based on comparison of a current frame`s pixel with a preceding frame`s pixel. A pixel block movement phase value is determined from the pixel movement phase value, for a block of pixels of the current frame by a motion detector (21). The current frame is divided into a region based on the determined value by a statistics and segmentation unit, where the region has an integral number of blocks. A region movement phase value is assigned from the block movement value to the region.
