Image processing apparatus with white balance control

摘要

An image processing apparatus comprises a coefficient generation circuit for generating a coefficient such as to decrease as a level of a luminance signal which is obtained by processing an input image signal increases while exceeding a predetermined limit value and to decrease as the luminance signal level decreases to a value lower than a predetermined lower limit value, a multiplier for multiplying a color difference signal which is obtained by processing the input image signal and the coefficient generated from the coefficient generation circuit, an integrating circuit for integrating the multiplication output from the multiplier into a plurality of predetermined regions on a screen, and a white balance control circuit to control the white balance of the screen by using the integration output of the integrating circuit.
