IMAGE ENCODING APPARATUS AND IMAGE ENCODING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an image encoding apparatus capable of encoding a high-resolution image under a limitation in memory capacity.

SOLUTION: The image encoding apparatus performing wavelet transform processing using a coefficient line buffer, comprises: an image input section 201 for inputting an image to be encoded; a code block size determining section 202 for determining the longitudinal size of a code block being the minimum unit of encoding, on the basis of the lateral size of the image input by the image input section 201; and an image encoding section 203 for encoding the image using the size of the code block determined by the code block size determining section 202.
