Image capture apparatus and control method therefor |
摘要 |
A specific subject region is detected, and if a focus detection area that is encompassed in the specific subject region is present, focus detection is performed on that focus detection area. This makes it possible to reduce the influence of a conflict between far and near subjects and reduce the amount of time required for focus detection in an image capture apparatus and in a control method therefor, the image capture apparatus being for performing automatic focus detection based on contrast evaluation values for a plurality of focus detection areas that are each located at a fixed position and each has a fixed size. |

1. An image capture apparatus comprising:
a focus detection unit configured to perform focus detection based on a contrast evaluation value for an image included in a focus detection area; a subject detection unit configured to detect a region of a specific subject from an image; and a selection unit configured to select at least one focus detection area, on which focus detection is performed by the focus detection unit, from among a plurality of preset focus detection areas each being located at a fixed position and having a fixed size, wherein the selection unit is configured to, when the region of the specific subject is detected and a focus detection area that is encompassed by the region of the specific subject is present among the plurality of preset focus detection areas, select the focus detection area that is encompassed by the region of the specific subject, and when the region of the specific subject is detected and no focus detection area that is encompassed by the region of the specific subject is present among the plurality of preset focus detection areas, select at least one predetermined focus detection area from among the plurality of preset focus detection areas. |
