Solid state color pickup device

Abstract

Abstract PURPOSE: To enhance the light using efficiency with increased resolution by forming the mosaic-type color filters so that it may always transmit in common one of the red, green and blue components. CONSTITUTION: The optional adjacent four units of the mosaic-type color filters are composed always of different types of filters. In other words, one of the four filters is always the W-filter along with one of the R, G and B filters plus of two of the complementary filters containing the transmission light component of the filter which is selected among the R, G and B filters. As a result, the using efficiency of the light can be enhanced greatly. Furthermore, the output of the optional two adjacent horizontal lines are added together in order to always obtain the (2R+G+ B) signal, (R+2G+B) signal or (R+G+2B) signal. In addition, the four photo detectors all can receive the green component, thus increasing greatly the resolution in the oblique direction. COPYRIGHT: (C)1980,JPO&Japio
