Abstract:
A focus control apparatus having a first mode in which a position of a focus lens is automatically changed, and a second mode in which the position of the focus lens is manually changed, the focus control apparatus comprises: a setting unit configured to set a first area in the first mode and a second area in the second mode; a focus detection unit configured to detect a focus state based on signals output from areas of an image capturing unit; and a focus control unit configured to control the position of the focus lens in the first mode, wherein upon switching from the second mode to the first mode again, the setting unit sets the first area based on a second area that has been determined to be in an in-focus state.
