Patent attributes
A focus detecting apparatus includes a receiving unit receiving designation of a position in a region of an image, a setting unit setting a first region in the image, an object detecting unit detecting a region of an object corresponding to the first region in continuously acquired images, a focus detection unit detecting a focusing state based on a signal from the image capturing unit corresponding to the detected object region, and a calculating unit calculating a predetermined index related to focusing state. If the predetermined index of a second region indicates a first state, the setting unit sets the first region based on the second region. If the predetermined index of the second region indicates a second state and the predetermined index of a third region near the second region indicates the first state, the setting unit sets the first region based on the third region.
