Abstract PURPOSE:To enlarge the allowable range of positioning between a mosaic filter and an image pickup element to facilitate positioning, by arranging main and sub-filters alternately in the X direction. CONSTITUTION:Main filter (cyanine) 3 and green filter 2 on the first line in the X direction are arranged alternately, and a red corretion filter is arranged between them. On the second line, red filter 1 and green filter 2 of main filters are arranged alternately, and the correction filter of cyanine is arranged between them. The color of auxiliary filters on each line is set to the same. The color mosaic filter and the image pickup element are so positioned that main filters 1, 2 and 3 may be arranged in the center of picture element 4 and auxiliary filters may be placed in both sides. If areas of main and auxiliary filters are set to 2/3 and 1/3 respectively, the luminance signal becomes the same signal for any scanning.
