Abstract

A solid-state color imaging device is provided including a plurality of photosensors which are arrayed in horizontal and vertical directions, and a mosaic color filter made up of filter elements arranged in correspondence with the respective photosensors. The mosaic color filter is arranged such that any group of four adjacent filter elements comprises a first filter which is made for panchromatic transmission, a second filter which is selected from among a first spectral region-transmitting filter, a second spectral region-transmitting filter and a third spectral region-transmitting filter respectively exhibiting different transmission characteristics, and third and fourth filters which are made of complementary color filters which transmit the transmission light component of the second filter and which have transmission components different from each other. The solid-state color imaging device also has means for simultaneously reading out optical signals of two of the photosensors adjacent in the vertical direction, and means for adding the two output signals.
