摘要： An image pickup apparatus that can efficiently obtain an offset between focal positions detected in phase difference-based focus detection and contrast-based focus detection by using results of phase difference-based focus detection at multiple points. Focal positions in a plurality of regions based on a pair of image signals obtained from different pupils are obtained. A focal position for a focus lens at which a contrast of image signals for image pickup is at a peak is detected. A target focal position is determined from the plurality of focal positions. When another focal position is present between a present focal position and the target focal position, an offset between a focal position of the focus lens at which the contrast detected at the other focal position while the focus lens is moving is at a peak and the other focal position is calculated.
