ABSTRACT:
Full color resolution of an image is realized by reconstructing an array of image data points from an image signal representing the image into a shifted array of pseudo pixels. The particular grid type of the array will dictate whether color recovery uses only vertical resolution, only horizontal resolution, vertical resolution followed by horizontal resolution, or horizontal resolution followed by vertical resolution. For each color channel, interpolation of missing color components is accomplished by first, taking a DCT of the image data points, then taking a modified IDCT of the DCT coefficients.
