APPARATUS AND METHOD FOR CORRECTING SIGNAL AND COLOR DEGRADATION IN A VIDEO IMAGE USING KNOWN ICONS FROM VIDEO IMAGE

摘要

There is disclosed an apparatus for correcting the color of objects appearing in a video image. The apparatus comprises: 1) a frame buffer for receiving and storing a first video frame from an incoming baseband video signal; 2) a memory for storing known pixel data corresponding to a plurality of known icons, the known pixel data comprising true color data values associated with the plurality of known icons; and 3) a color correction controller for comparing captured pixel data from the stored first video frame with the known pixel data stored in the memory and detecting a first actual image of a first known icon appearing in the stored first video frame. The color correction controller also compares a first true color data value associated with the first known icon and a first actual color data value associated with a first actual color in the first actual image of the first known icon. In response to the comparison, the color correction controller determine a first color correction factor associated with the first actual color data value.
