Abstract
It is an object of the present invention to provide a single board type color image sensor which can suppress the reduction of detection luminance range while enlarging detection color range. The color image sensor of the present invention has pixel blocks arranged in an array state, each pixel block comprising a first pixel detecting red light, a second pixel detecting green light, a third pixel detecting blue light, and a fourth pixel detecting light having a wavelength between the green light and the blue light or between the green light and the red light. Further, sensitivity of the fourth pixel to the above-mentioned light is kept lower than sensitivity of the second pixel to the green light.
