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.

What is claimed is: 1. An image pickup apparatus comprising: a focus tens; a signal processing device that outputs a video signal from an optical image formed through said focus lens; a lens driving device that drives said focus lens; a first detecting device that detects a focus signal from the video signal output from said signal processing device; a second detecting device that detects a phase difference between a pair of image signals of a subject passing through different light paths; a focus adjusting device that adjusts focus based on results of detection by said first detecting device and said second detecting device; a storing device that stores a plurality of locus information; and a power control device that controls, when zooming from telephoto to wide angle is performed and the result of detection by said first detecting device shows that the image pickup apparatus is an in-focus status, to cut off power to said second detecting device; wherein said power control device further controls, after said focus adjusting device finishes adjusting the focus and when zooming from wide angle to telephoto is performed, to supply the power to said second detecting device so as to cause said second detecting device to detect the phase difference, select one of the stored plurality of locus information based on the detected phase difference, and track a cam locus based on the selected locus information.
