Abstract
A sensor has first pixels each including one of red, green and blue color filters, and second pixels each including one of red, green and blue color filters. In the first and second pixels including color filters of the same color, light transmittances of the light transmissive portions are different. A light transmittance of the light transmissive portion of the first pixel including the red color filter is lower than that of the light transmissive portion of the first pixel including the green color filter, and a light transmittance of the transmissive portion of the first pixel including the green color filter is lower than that of the light transmissive portion of the first pixel including the blue color filter.
