摘要

PROBLEM TO BE SOLVED: To improve encoding efficiency when a macro block of a moving image is further divided into partitions and areas adjoining each other across a partition border have high spatial correlation.SOLUTION: In a moving image encoding device 10, a frequency conversion determination part 105 determines whether conversion object areas adjoining each other across a partition border are integrated. A conversion coefficient generation part 107 generates a conversion coefficient by applying single frequency conversion to the conversion object areas determined by the frequency conversion determination part 105 to be integrated.
