Abstract

A dual type imaging device includes a first CCD and a second CCD, on which complementary color filters with a checkerboard (or matrix) arrangement are disposed. The complementary color filters have the same construction as each other, having magenta elements, yellow elements, cyan elements and green elements arranged in a regular manner. The arrangement of the color elements of the filter of the first CCD is offset, by a width of one light-sensitive element, with respect to the arrangement of the color elements of the filter of the second CCD. An R-signal, a G-signal and a B-signal are sensed in accordance with four light-sensitive elements which are arranged in a 2.times.2 matrix.
