System and method of detecting strobe using temporal window

摘要

A video processing device is provided that includes a buffer, a luminance component, a maximum threshold component, a minimum threshold component and a flagging component. The buffer can store frame image data for a plurality of video frames. The luminance component can generate a first luminance value corresponding to a first frame image data and can generate a second luminance value corresponding to a second frame image data. The maximum threshold component can generate a maximum indicator signal when the difference between the second luminance value and the first luminance value is greater than a maximum threshold. The minimum threshold component can generate a minimum indicator signal when the difference between the second luminance value and the first luminance value is less than a minimum threshold. The flagging component can generate a flagged signal based on the maximum indicator signal and the minimum indicator signal.

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.
