Abstract
A registration correction circuit for a solid-state camera having a plurality of solid-state image pickup elements. One of the color video signals produced from the image pickup elements is selected as a reference signal, and pixel data of the color video signals other than the reference signal are electronically moved so that the pixel data of all the color video signals will agree in their positions. Movement of pixels is carried out by using coordinate transformation and interpolation technique: the coordinate transformation is used to shift the pixels by a multiple of 1-pixel pitch; and the interpolation is used to shift the pixels by less than 1-pixel pitch. The spatial frequency components reduced by the interpolation calculations are adaptively enhanced for each pixel in real time.
