Video window detection

摘要

A video window detector includes a region characteristic determiner to generate at least one characteristic value for at least one region of a display output; a characteristic map generator to generate an image map from the at least one characteristic value for at least one region of the display output; and a window detector to detect at least one video window dependent on the image map.

1. A video detection method comprising:
providing first and second video windows that overlap, the first and second video windows each playing a video therein; using at least one of horizontal and vertical continuous edges within an overlap video region of the first and second video windows to create separations between the first and second video windows; differentiating the first video window from the second video window based upon the separations created by at least one of the horizontal and vertical continuous edges; determining whether the first video window overlaps the second video window or whether the second video window overlaps the first video window; if the first video window overlaps the second video window, enhancing the video playing in the first video window and not the video playing in the second video window in the overlap video region based upon the differentiation of the first video window from the second video window, the enhancing being performance of noise reduction on the video playing in the first video window; and if the second video window overlaps the first video window, enhancing the video playing in the second video window and not the video playing in the first video window in the overlap video region based upon the differentiation of the first video window from the second video window, the enhancing being performance of noise reduction on the video playing in the second video window.
