<p>PURPOSE:To improve resolution, color reproducibility, sticking accuracy, etc., by placing plural saturation filters in front of a picture element, and placing a filter of the same color in front of a boundary in the prescribed direction of the picture element or its vicinity. CONSTITUTION:A complementary color filter is constituted of plural saturation filters, and also a boundary between this complementary color filter and other adjacent filter, or its vicinity is made to have the same color. In this way, by using many filters for forming a complementary color as a color filter, substantial sampling frequency is raised even in case of an object to be photographed, whose color saturation degree is high, and folded distortion is reduced. Also, a sticking error of the filter to the image pickup element can be offset by the same color filter provided on the circumferential part of this picture element. Also, a numerical aperture of the picture element is improved, and the sensitivity is raised.</p> |
