Image processing apparatus, image processing method, and non-transitory computer-readable storage medium

An image processing method comprising:

• calculating a code amount obtained upon coding a coding block, the coding block being obtained by dividing an image to be processed;
• on the basis of a reference code amount, and the code amount calculated in the calculating for each of coding blocks in a coding group including a plurality of coding blocks, determining an assigned code amount to be assigned to each of the coding blocks;
• and
• generating coded data by coding each of the coding blocks using the assigned code amount as a target code amount,
• wherein in the determining, the assigned code amount is determined so that a total of the assigned code amounts of the coding blocks in the coding group is the same among a plurality of coding groups, and
• in the generating coded data, fixed-length coding is carried out on a coding group-by-coding group basis by coding using the determine assigned code amounts.

A non-transitory computer-readable storage medium storing one or more programs including instructions that, when executed by a processor of an image processing apparatus, causes the processor to perform the operations of:

• calculating a code amount obtained upon coding a coding block, the coding block being obtained by dividing an image to be processed;
• on the basis of a reference code amount, and the code amount calculated in the calculating for each of coding blocks in a coding group including a plurality of coding blocks, determining an assigned code amount to be assigned to each of the coding blocks;
• and
• generating coded data by coding each of the coding blocks using the assigned code amount as a target code amount,
• wherein in the determining, the assigned code amount is determined so that a total of the assigned code amounts of the coding blocks in the coding group is the same among a plurality of coding groups, and
• in the generating coded data, fixed-length coding is carried out on a coding group-by-coding group basis by coding using the determined assigned code amounts.
