摘要： An encoding apparatus generates low-frequency component subband data and high-frequency component subband data from image data; generates, from low-frequency component subband data generated from first image data, second image data that has a same resolution as that of the first image data. The apparatus obtains a difference between high-frequency component subband data generated from the first image data and high-frequency component subband data generated from the second image data; and encodes the low-frequency component subband data of the first image data and the difference in order to generate encoded data.

摘要： The present invention provides a technique for encoding Bayer array RAW image data that responds to whether priority is placed on encoding efficiency or on image quality. To that end, a first plane transforming unit transforms the RAW image data into R, G0, G1, and B planes. A second plane transforming unit transforms the RAW image data into a luminance plane and three color difference planes, each constituted of a different color difference component. It is then determined whether to encode using the first plane transforming unit or the second plane transforming unit, and the planes are then encoded according to the determination.

摘要： 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.

摘要： A technique is provided that can record moving images while not resulting in calculation load increase and maintaining a certain degree of image quality even when encoding corresponding to a 4:4:4 format. Provisional encoding is performed, by obtaining motion vectors in accordance with a plurality of mutually different search ranges of image data of one color component, on a preset number of frame images at an initial stage at a time when an encoding start instruction is given. Moreover, the search range having the smallest error vector among each of the search ranges is determined as a search range for a motion vector, for each color component in main encoding processing carried out following provisional encoding.
