ABSTRACT:
A method for multiplying the frame rate of an input video signal having a line rate fHin and a frame rate fVin, comprising the steps of: propagating the input video signal through just enough memory to delay the input video signal by a fraction of a frame period 1/fVin; speeding up the delayed video signal to a first line rate faster than fHin; speeding up the input video signal to a second line rate faster than fHin; supplying the speeded up video signal and the delayed speeded up video signal sequentially, one line at a time; and, writing the sequentially supplied lines into a liquid crystal display at the faster line rate, thereby writing at least some of the lines multiple times within each the frame period. A corresponding apparatus can comprise: a partial frame memory; two speedup memories; a multiplexer; and, a source of clock and control signals.
