Abstract

A first solid-state imaging element and second and third solid-state imaging elements are arranged spatially so as to be horizontally shifted half a pixel pitch from one another so that a light-sensitive portion of each pixel of the second and third solid-state imaging elements may correspond to a light-insensitive portion of each pixel of the first solid-state imaging element. A high-frequency component synthesizer circuit produces the high-frequency components of a luminance signal on the basis of the signal E.sub.G obtained by performing nonlinear process on the output of the first solid-state imaging element and the signal E.sub.R +E.sub.B obtained by performing nonlinear process on the outputs of the second and third solid-state imaging elements and mixing the resulting signals. At this time, based on the result of comparing the output signal of the first solid-state imaging element with the respective output signals of the second and third solid-state imaging elements, the mixing ratio of signal E.sub.R to E.sub.B is controlled.
