Abstract
The present invention has a converting unit that converts image data in a Bayer array into three planes consisting of G, B and R planes that have the same array relationship as YCC 422, and an encoding unit that performs prediction encoding of the G, B and R planes obtained by the converting unit as YCC 422 image data. Here, the number of pixels in the horizontal direction of the G plane is twice the number of pixels in the horizontal direction of the B or R plane. Also, the encoding unit includes a motion searching unit that obtains a motion vector of a pixel block to be encoded as a motion vector of the G plane, and a correcting unit that corrects a motion vector of the B and R planes based on the motion vector for the G plane.
