Abstract:
An electronic device disclosed herein includes an adaptive comb to generate a combed video image from an image signal using frame combing or field combing, and a controller. The controller includes a field motion detector to determine a field motion value for a region as a function of field motion between adjacent fields of the image signal, and controller logic to generate a control signal to cause the adaptive comb to selectively comb the region using the frame combing or the field combing based upon the field motion value. The control signal causes the adaptive comb to process the region using frame combing when the field motion value is less than a first motion threshold value, process the region using field combing when the field motion value is indicative of motion, greater than the first motion threshold value, and less than a second motion threshold value.
