Method and apparatus for converting motion image data, and method and apparatus for reproducing motion image data

摘要

A motion image data conversion apparatus includes an input unit configured to input motion image data in the form of color mosaic image data each pixel of which has single-color component data, and a spatial decimator configured to input motion image data from the input unit and perform a spatial decimation process separately on each color component data of the color mosaic image data. The spatial decimator selects one or more representative values for each color component data of the color mosaic image data and produces spatially decimated data composed of selected representative values.
