Abstract
This invention provides a color still image sensing apparatus and method, which can obtain image quality as high as that of the three-plate type with cost as low as the single-plate type, and can prevent the input time from becoming redundant. A solid-state image sensing device, which has an image sensing surface made up of a large number of photoelectric conversion elements arranged in a matrix and to the front surface of the image sensing surface of which a color filter having different color component regions in correspondence with the arrangement intervals of photoelectric conversion elements is fixed, is used, the irradiation region of incident light with respect to the solid-state image sensing device is changed in units of arrangement intervals of the photoelectric conversion elements by displacing the solid-state image sensing device and the incident light with respect to the solid-state image sensing device relative to each other along the image sensing surface in units of arrangement intervals of the photoelectric conversion elements, and image data of the solid-state image sensing device sensed at a plurality of changed positions are synthesized to an image.
