Abstract
An image pickup apparatus includes an image pickup unit including two-dimensionally arranged photoelectric conversion elements, the image pickup unit being configured to perform an photoelectric conversion of an object image formed on an image pickup plane and to output an image signal, a detector configured to detect a focus signal based on the image signal obtained by moving a focus lens, and a controller configured to find an in-focus direction based on the focus signal and to provide a control so that the focus lens can be moved in the in-focus direction. The controller selects one of a plurality of interruption timings that occur in a synchronization signal in moving the focus lens, and starts moving the focus lens with a selected interruption timing.
