Patent ID: 7515820

Claim:
An image capture device comprising: a motor which moves a focus lens; an automatic-focusing unit which compares contrast values of captured images that are sequentially obtained through an image capture element when the focus lens is moved by the motor, and which detects a focused position of the focus lens based on results of the comparisons; a shutter button which is half pressable and fully pressable; a first determining unit which determines whether the shutter button is half pressed; a second determining unit which determines whether the shutter button is fully pressed; a first automatic-focus control unit which, when the first determining unit determines that the shutter button is half pressed, executes a first automatic-focusing processing by using the automatic-focusing unit; and a second automatic-focus control unit which, when the second determining unit determines that the shutter button is fully pressed, executes a second automatic-focusing processing with a higher processing speed than that of the first automatic-focusing processing by using the automatic-focusing unit, wherein the first automatic-focus control unit comprises a first comparator which, when the first automatic-focusing processing is executed, compares contrast values of the captured images obtained through the image capture element at each of positions of the focus lens that are specified based on a first lens-position interval, and wherein the second automatic-focus control unit comprises a first comparator which, when the second automatic-focusing processing is executed, compares contrast values of the captured images obtained through the image capture element at each of positions of the focus lens that are specified based on a second lens-position interval which is set by controlling the motor and which is wider than the first lens-position interval.
