Patent ID: 6909440

Claim:
A stepped-decay video morphing method, to modify video signals for use with a display having disparate turn-on/turn-off characteristics, comprising the following steps: (a) for a first pixel position, comparing the signal intensity for a new image (termed “NEW” pixel intensity) to the signal intensity for a prior image (termed “OLD” pixel intensity); (b) for a NEW pixel intensity within an intensity range from equal to, to greater than, the OLD pixel intensity, changing the signal intensity for the first pixel position to said NEW pixel intensity; (c) for a NEW pixel intensity below the intensity range specified in step (b), incrementally decreasing the signal intensity for the first pixel position to a first intermediate intensity between the OLD and NEW pixel intensities, said first intermediate intensity selectable by an operator viewing said display; and (d) decreasing the signal intensity for the first pixel position from an intermediate intensity to the NEW pixel intensity.
