The digital processing cameras are now being developed actively, because in recent years CMOS gate arrays of sufficient speed and scale have been achieved. Because a digital image processor has ideal signal delay and no crosstalk, digital processing camera has clear image quality, however, the smoothness of the image is inferior to that of an analog processing camera. It is found that if moire is produced by the contour compensator the image smoothness is inferior and the moire is mainly generated by nonlinear process. To reduce aliasing components of nonlinear process harmonics, a double-sampling rate contour-compensator is developed. This compensator erases the greater part of conventional compensator moire and increases image smoothness. This paper describes contour-compensator moire-generating mechanism and moire-reducing contour-compensation method.
