ABSTRACT:
Apparatus for producing a color image signal having first and second color components, comprises an image sensor having a regular array of image sensing elements with a regular array of first and second colored filter elements registered thereon for producing a sampled color image signal having first and second color components, a lens for forming a color image on the image sensor, an optical device for displacing the first color component of the image with respect to the second color component by an amount equal to an integral number of image sensing elements such that neighboring image sensing elements having first and second colored filter elements sample the same portion of the image, and a delay device for synchronizing the color components of the image by delaying the first color component with respect to the second color component of the sampled color image signal produced by the image sensor by an integral number of image sensing element sample periods corresponding to the displacement of the first color component with respect to the second color component. The image produced from the resulting signal is free from color fringing.
