ABSTRACT:
An image pickup apparatus which is capable of restraining power consumption to the maximum possible extent while improving the AF and zooming performance using distance information. A video signal from an optical image formed through the focus compensation lens is output by a camera signal processing circuit. A focus signal is detected from the video signal by an AF signal processing circuit. Two image signals are detected by an external ranging unit. Focus is adjusted based on results of detection by the AF signal processing circuit and the external ranging unit. A shooting state and an operative state of the image pickup apparatus are determined by an AF microprocessor. Power supply to the external ranging unit is controlled in response to the states determined by the AF microprocessor.
