APPARATUS AND METHOD FOR PROCESSING IMAGE AND CONTROL PROGRAM

PROBLEM TO BE SOLVED: To provide an image processing apparatus outputting a video image that does not give sense of incongruity to a viewer by making a frame skip inconspicuous on a display screen, the frame skip being caused by replacing a video image signal with a synchronization signal.SOLUTION: The image processing apparatus 10 includes: a moving amount detecting part 3 for detecting the moving amount of each frame of video image data and identifying a frame of which the moving amount is lower than a threshold of a moving amount as a low operation frame; a write control part 5 for controlling write of a frame to a memory 7; a read control part 6 for controlling read of the frame from the memory 7; and a capacity monitoring part 4 for calculating the spare capacity of the memory 7, and outputting to a write control part 5 a skip instruction signal Sfor instructing a limitation on low operation frame write into the memory 7 when the spare capacity of the memory falls below a predetermined allowable range, wherein the write control part 5 determines whether to write the low operation frame into the memory 7 on the basis of the presence/absence of the skip instruction signal S.
