Patent ID: 8200081

Claim:
An image capturing apparatus, comprising: an image sensor that photo-electrically converts an object image formed by an optical lens, a focus detection unit that detects the focus state of the object image using an image signal from a focus detection region within a frame of the image sensor, a setting unit that sets the focus detection region in accordance with a focus detection mode that is selected by a user from a plurality of focus detection modes including a first focus detection mode and a second focus detection mode, and a storage unit that stores at least one of the size and the position of the focus detection region for the case that the first focus detection mode is selected and the case that the second focus detection mode is selected respectively, wherein the setting unit sets one focus detection region when the first focus detection mode is selected and sets a plurality of focus detection regions when the second focus detection mode is selected, and wherein at least one of the size and the position of the plurality of focus detection regions is changed together as one group when the second focus detection mode is selected.
