Abstract:
A color still image sensing apparatus comprising:a solid-state image sensing device having an image sensing surface made up of a large number of photoelectric conversion elements arranged in a matrix with rows of photoelectric conversion elements in a horizontal direction and columns of photoelectric conversion elements in a vertical direction;a color filter fixed to a front surface of the image sensing surface of said solid-state image sensing device and having different color component regions in correspondence with arrangement intervals of the photoelectric conversion elements to form a matrix with rows of color component regions in the horizontal direction and columns of color component regions in the vertical direction;driving means for displacing said solid-state image sensing device and an incident light with respect to said solid-state image sensing device relative to each other along the image sensing surface in units of arrangement intervals of the photoelectric conversion elements so as to change an irradiation position of the incident light with respect to said solid-state image sensing device, the driving means displacing the solid-state image sensing device and the incident light intermittently at a distance of one pixel, a half pixel, or a combination thereof;storage means for recording image data of said solid-state image sensing device sensed at a plurality of positions corresponding to the irradiation positions changed by said driving means; andprocessing means for reading out the image data stored in said storage means and synthesizing the readout image data into a still image having pixels that each include components of all color information contained therein,wherein said driving means displaces said solid-state image sensing device and the incident light a plurality of number of times, so that an irradiation region of the incident light having a size corresponding to a size of the photoelectric conversion element moves to all types of adjacent color component regions of said color filter of said solid-state image sensing device,wherein the driving means is configured to displace the solid-state image sensing device and incident light with respect to the solid-state image sensing device relative to each other along the image sensing surface either in the horizontal direction across a row or in the vertical direction across a column,wherein the driving means is configured to displace the solid state image sensing device and the incident light with respect to the solid state image sensing device relative to each other in relation of the color component regions of the color filter until three different color components are extracted.
