Abstract:
An image sensing apparatus, comprising:a solid-state image sensor having a plurality of light receiving elements which accumulate an information charge by photoelectric conversion; a color separation filter arranged in front of the solid-state image sensor and having a plurality of filter segment groups, which include a first color filter segment group having a first color selected from the three primary colors of light and second and third color filter segment groups having the complementary colors of the non-selected two of the three primary colors, wherein each filter segment group includes a plurality of filter segments each of which corresponds to each one of the light receiving elements; a monochromatic filter movably arranged between a position in an optical path to the plurality of light receiving elements and a position away from the optical path to the plurality of light receiving elements, wherein the monochromatic filter has substantially the same first color as the first color filter segment; and a driver connected to the solid-state image sensor for transferring the information charge accumulated by the plurality of the light receiving elements in a predetermined order and driving the solid-state image sensor so as to output an image signal therefrom.
