Abstract
By applying the offset sampling using four-plane prism provided with four solid state imaging devices at four light output planes, chromatic aberration of lenses is eliminated even to the peripheral part of the imaging plane, and moire suppression effect is much enhanced. Furthermore, by using a plural number of matrix circuits, and by producing the luminance signal by changing the matrix ratios in low frequency range and in high frequency range, moire suppression effect is further enhanced, and luminance error is also eliminated.
