Abstract
A field motion suppression technique in interlaced video displays produces a motion suppressed frame without the use of a fixed threshold for motion detection. One of two interlaced fields is selected to remain unchanged, and the other field is examined on a pixel by pixel basis using vertical pixels both above and below from both fields to determine motion for each pixel. When motion is detected for a pixel, the pixel value is replaced with an interpolated value from the unchanged field, otherwise the pixel value is left unchanged.
