Abstract
A multi-chip type CCD color camera is designed to displace respective chips relative to an object image. The sampling action at respective CCD imager chips yields output signals having base-band components and sideband components partially overlapped with each other. In order to separate two components, frequency converting technique is introduced in the signal processing circuit, wherein these components are interchanged in frequency. It is very easy to cancel out original base-band components from respective CCD chips, because the phases of the base-band components are not influenced by chip displacement. Accordingly, there is no need to adjust precise chip alignment in order to improve the resolution of the CCD color camera.
