ABSTRACT:
The color quality of a received color picture signal is detected by a device for measuring the intensity of at least the red component and the green component of the picture signal. A microprocessor determines a correction value for the white balance correction on the basis of the detected color quality and corresponding to selectable correction values, stored in a memory, for each color component. The method and apparatus permit an application specific correction of the white balance, particularly for use in endoscopic systems, such as video endoscopes and endoscope cameras, to be used in different body organs which cause different color shifts.
