Image pickup apparatus that displays image based on signal output from image pickup device, method of controlling the same, and storage medium
An image pickup apparatus that makes it unnecessary to temporarily stop image pickup performed by an image pickup device to thereby improve operability of the image pickup apparatus, and achieves power saving. In an image pickup apparatus having an electronic viewfinder function, first image signals for live view are acquired by thinning read lines of an image pickup device, and second image signals for AF evaluation value calculation are acquired from the other read lines at a higher speed than the first image signals, for simultaneous output with the first image signals. Reading of the second image signals is started when the state of the object of image data changed or when one photographing mode is changed to another by a user's operation, and is terminated when a reading termination condition set in advance in association with the reading start condition is satisfied.
