Abstract

An image compression device includes: a first encoder that encodes a target block included in a segment in a first encoding mode; a second encoder that encodes the target block in a second encoding mode using a fixed-length coding to obtain a second encoded data; a calculator that calculates an accumulated amount of the first encoded data of the blocks; a selector that selects an encoding mode to be used to encode the target block from among the first encoding mode and the second encoding mode; and a determiner that determines whether to encode encoding mode information according to a predetermined condition. The selector selects the second encoding mode if a sum of an accumulated amount and an amount of the second encoded data of all remaining blocks in a segment exceeds a target value.
