MOVING IMAGE ENCODING APPARATUS AND MOVING IMAGE ENCODING METHOD

摘要

PROBLEM TO BE SOLVED: To suppress image quality deterioration in an inter-frame when encoding a moving image using motion prediction.

SOLUTION: An encoding section (206) for encoding a moving image using inter-frame motion prediction includes: a a dividing part (302) for dividing each frame into a plurality of divided areas; an ROI tile determining part (317) for determining an important area out of the frames; inter-frame predicting means (310, 314) for searching highly correlated pixel sets for each divided area of the frame as an encoding target within the range of the important area of the preceding frame, and outputting differential data while taking a difference between data in the divided area and data of the searched pixel sets; and encoding means (303-308) for encoding the differential data.
