ABSTRACT:
An image pickup apparatus includes image pickup circuitry for producing an image signal in response to a received image. Detecting circuitry is provided for detecting (1) a phase of a flicker component associated with a light source, and (2) a relationship between the detected phase of the flicker component and the timing of producing the image pickup signal by the image pickup circuitry. A control circuit is provided for controlling a white balance of the output of the image pickup circuitry based on the output of the detection circuitry.
