Automatic focus detection apparatus, control method for the same, and image pickup apparatus
Abstract:
In the case where a predetermined subject can be detected from an image with a first detection method but cannot be detected with a second detection method, an in-focus direction of a subject detected with the first detection method is determined during a focusing operation. In the case where, when the predetermined subject becomes detectable with the second detection method, the in-focus direction of the predetermined subject detected with the second detection method has been determined by a determination unit, the focus-detecting operation is started using the determined in-focus direction. Speeding up of the focus-detecting operation that utilizes subject detection results is thereby realized, while suppressing any drop in the image quality of recorded images.
