Abstract

An image capture apparatus includes an image capture unit, a first focus detection unit configured to perform phase difference type focus detection for detecting a deviation amount between a pair of object images acquired from output signals output from the image capture unit, a second focus detection unit configured to perform contrast type focus detection for detecting contrast information of an object image acquired from an output signal output from the image capture unit, a contrast information generation unit configured to generate the contrast information in a plurality of distance measurement areas subjected to focus detection by the second focus detection unit, and an area determination unit configured to determine, based on the contrast information, a distance measurement area to be subjected to focus detection by the first focus detection unit.

First claim

What is claimed is:

1. An image capture apparatus comprising:
an image capture unit;
a first focus detection unit configured to perform phase difference type focus detection for detecting a deviation amount between a pair of object images acquired from output signals output from the image capture unit;
a second focus detection unit configured to perform contrast type focus detection for detecting contrast information of an object image acquired from an output signal output fro…
