Abstract: A bit-reversing method and system are disclosed for linearly scaling an image frame horizontally, vertically or both. The system includes a counter circuit for outputting the current frame-column number of the currently scanned pixel and the current frame-row number of the currently scanned frame-row. The numbers are bit reversed in a converter circuit. The bit-reversed current frame-column number is compared in a comparator circuit to a horizontal scaling constant which equals the number of pixels to be discarded in each frame-row of the image frame. The bit-reversed current frame-row number is compared in the comparator circuit to a vertical scaling constant which equals the number of frame-rows of the image frame to be discarded. If the bit-reversed current frame-row number is greater than the vertical scaling constant then the comparator circuit outputs appropriate signals to a scaling controller and an address generator for storing the currently scanned frame-row in a frame buffer.
