ABSTRACT:
A method for suppressing the perception of flicker in interlaced video images, includes the steps of: testing, each pixel in an image, for an intensity value below a first predetermined threshold; modifying, for each tested pixel, an intensity value representation for each nearest neighbor pixel along a first axis of said interlaced image having an intensity value exceeding a second predetermined threshold, if the intensity value of the tested pixel is below the first predetermined threshold; displaying, on a video display device, an interlaced image generated by the steps of testing and modifying, having a suppressed perception of flicker.
