Abstract:
1. A moving image converting apparatus for executing data conversion processing of moving image data, the apparatus comprising: a block dividing unit for executing block division processing for each frame that forms the moving image data; a motion amount detecting unit for detecting a block motion amount corresponding to the motion amount of an object contained in each of a plurality of blocks obtained by the block division processing in the block dividing unit; a line-of-sight motion amount detecting unit for calculating a line-of-sight motion amount of a viewer who views the moving image data; a sampling point phase change amount determining unit for receiving the block motion amount and the line-of-sight motion amount as input, and for determining a block-corresponding sampling point phase change amount to be applied to spatial decimation processing on each of the blocks, wherein the sampling point phase change amount determining unit is configured to execute the sampling point phase change amount determination processing, to which image quality rating curves as results of measurement of image quality rating corresponding to various values of the block motion amounts are applied, such that the sampling point phase change amount determining unit executes a decimation executing unit for receiving the blocks obtained by the block division processing in the block dividing unit as input, and for executing the spatial decimation processing being executed by applying the block-corresponding sampling point phase change amount determined by the sampling point phase change amount determining unit, and wherein the block-corresponding sampling point phase change amount is determined by selecting a sampling point phase change amount which corresponds to a rating equal to or above the present reference rating.
