Moving image converting apparatus, moving image converting method, and computer program

摘要

A moving image converting apparatus includes: a block dividing unit executing block division processing for each of frames that form the moving image data; a motion amount detecting unit detecting a block motion amount corresponding to a motion amount of an object contained in each of blocks obtained; a line-of-sight motion amount detecting unit calculating a line-of-sight motion amount of a viewer who views the moving image data; a sampling point phase change amount determining unit receiving the block motion amount and the line-of-sight motion amount as input, and determining a block-corresponding sampling point phase change amount to be applied to spatial decimation processing on each of the blocks ; and a decimation executing unit receiving the blocks obtained as input, executing the spatial decimation processing on the inputted blocks, the spatial decimation processing being executed by applying the block-corresponding sampling point phase change amount determined.
