ABSTRACT:
A dynamic white balance control circuit is provided which is capable of dynamically setting a white balance and/or a color temperature according to a level of an input image signal. The dynamic white balance control circuit has a color component detecting circuit to-detect a difference between a black and white image region and a colored image region in a video signal input to output a color component detected result, a selecting circuit to select and output a white balance setting value designating a different color temperature according to the color component detected result indicating the black and white image region or the colored image region, and a white balance control circuit to calibrate a white balance of a video image input according to a selected white balance setting value and to produce a video signal output.
