Abstract
Apparatus and a method are described for modifying the magnification and registration factors of an image using digital signal processing and interpolation. The apparatus is used in a camera system which samples an image to generate sampled data signals. The sampled data signals are first interpolated across the either the rows or columns of the image and then across the columns or rows of the image to change the magnification and registration factors of the images represented by each of the sampled data signals to some common desired magnification and registration factors. The system electronically corrects for chromatic aberration and geometric distortion in the image caused by the lens system and skew among the images caused by misalignment of the respective color image sensors.
