ABSTRACT:
A system for digitizing, displaying and storing video images utilizing independent horizontal and vertical control circuitry to achieve the digitizing, storage and display functions. The independent control permits any of the pixels on a line to be independently sampled and digitized so that more resolution may be obtained in areas of interest without requiring excessive memory capacity. Similarly, any line or lines may be sampled to increase resolution in areas of interest. All or less than all of the stored video pixels may be displayed in patterns that are either the same as or different than those of the original video image.
