Japanese Patent JP3361077
Kind Code:
PROBLEM TO BE SOLVED: To sharply reproduce an outline in an image, to smoothly reproduce a segment and to reduce the deterioration of high resolution effect even if the image pickup device of a multi-disk type is operated at a wide dynamic range mode. SOLUTION: Plural images from plural solid-state image pickup elements 13 and 14 are synthesized by a control CPU 28, pixel interpolation circuits 19 and 20, a pixel position adjusting circuit 25 and an addition average circuit 26. A first mode operating a solid-state image pickup device so that the synthesized image obtain high resolution information and a second mode operating the solid-state image pickup device so that a dynamic range characteristic wider than the photoelectric conversion dynamic range of the respective solid- state image pickup elements is obtained are adaptively switched in accordance with the level of an image pickup output signal obtained from the respective image pickup elements. A pixel that a pixel interpolation processing circuit uses is switched between the first and second modes.
