Claim One:
1. An image capture apparatus capable of executing automatic focus detection of an imaging optical system, using a signal obtained from an image sensor, the apparatus comprising: acquisition unit configured to acquire (1) first image-forming position information obtained by performing, using a plurality of first weights, weighted addition on information regarding a plurality of image-forming positions of the imaging optical system, the information corresponding to different spatial frequencies, and (2) second image-forming position information obtained by performing, using a plurality of second weights, weighted addition on the information; correction unit configured to correct a result of the automatic focus detection based on a result of a comparison between the first image-forming position information and the second image-forming position information; and control unit configured to control a position of a focusing lens that the imaging optical system has, based on the corrected result of the automatic focus detection, wherein the plurality of first weights correspond to a first evaluated band at the time of appreciating an image that is based on a signal obtained from the image sensor, and the plurality of second weights correspond to a second evaluated band of the signal obtained from the image sensor, the second evaluated band being used in the automatic focus detection.
