Solid-state color image pickup device

Abstract

Abstract PURPOSE:To raise resolution and a utilizing rate of light, and to equalize an output signal of a filter position, by placing plural filter elements in accordance with each photodetector, and scanning simultaneously two pieces each of photodetectors adjacent in the vertical direction. CONSTITUTION:Two adjacent horizontal lines are scanned simultaneously by use of a filter which arrays in the horizontal direction a filter element train A obtained by placing alternately a yellow color transmission filter Ye and a cyan color transmission filter Cy, and filter element train B obtained by placing alternately an all-color transmission filter W and a magenta color transmission filter Mg. The filter element consists of a complementary color filter or an all-color transmission filter, therefore, a utilizing rate of light is high, and the balance of magnitude of a signal is improved in comparison with combination of a primary color transmission filter and the all-color transmission filter. Also, a signal of R+2G+B is obtained in an A train position, a signal of R+G+B is obtained in a B train position, and these signals are close to the ratio of a regular luminance signal, respectively, therefore, by adjusting the gain in each scanning position, a luminance signal is obtained at every picture element, and high resolution is obtained.
