Abstract:
1. An apparatus comprising: an image-pickup unit configured to perform image-pickup of an object image input through a focus lens; a setting unit configured to set a focus detecting area for detecting a focus state; a light control unit configured to control an amount of light incident on the image-pickup unit; a receiving unit configured to receive an instruction for focus adjustment and determination of a state of the light control unit; and a focus adjusting unit configured to detect a focus signal representing the focus state in the focus detecting area set by the setting unit to move the focus lens based on the focus signal; wherein the focus adjusting unit controls a first scan operation and a second scan operation, in the first scan operation the focus adjusting unit detects the focus signal before the receiving unit receives the instruction, and in the second scan operation the focus adjusting unit detects the focus signal after the receiving unit receives the instruction, and wherein the focus adjusting unit interrupts the first scan operation when a state of the light control unit is changed during the first scan operation.
