<p>PURPOSE:To improve resolution, color reproducibility and sticking accuracy, by placing plural saturation filters for forming a complementary color, on a light incident face of a picture element for forming a complementary color signal. CONSTITUTION:In case when a cyanic filter is constituted of a lot of G filters and B filters, it is shaped like a stripe, a mosaic, etc. in the horizontal direction. 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, in this way, the same color filter is placed in front of a boundary in the prescribed direction of the picture element or its vicinity, therefore, a numerical aperture of the picture element is improved, and the sensitivity is raised.</p> |
