Abstract:
1. A video processing device comprising: a buffer operable to store frame image data for a plurality of video frames; a luminance component operable to generate a first luminance value corresponding to a first image data from the buffered frame image data, and to generate a second luminance value corresponding to a second frame image data from the buffered frame image data; a maximum threshold component operable to generate a maximum indicator signal when the difference between the second luminance value and the first luminance value is greater than a maximum threshold; a minimum threshold component operable to generate a minimum indicator signal when the difference between the second luminance value and the first luminance value is less than a minimum threshold; and a flagging component operable to generate a flagged signal based on one of the maximum indicator signal and the minimum indicator signal.
