Abstract : A video zoom processor digitally processes video imagery information in a simultaneous two-dimensional format. Size and position transformation factors are incorporated in the image via processing. The size specification delay for the reduction factor is one video frame time and for the expansion factor it is zero video frame time. The specification delay for the position or translation factor is zero video frame time. Also implemented into the processed image is the pixel averaging algorithm in which each output pixel is the value of the weighted average of certain input pixels for purposes of gray level determination.
