Abstract
Abstract An image recording apparatus has a memory for directly storing a color signal supplied from a solid-state image sensor in a memory without applying color signal processing to that color signal, a selecting circuit for selecting block data of arbitrary size from the memory, and a matrix calculation circuit for converting the selected block data into a predetermined color or luminance signal.
