Abstract:
An optical control apparatus configured to control driving of a focus correction unit that moves for focusing along an optical axis of an optical system or a normal of an imaging surface, in imaging in which the optical axis tilts to the normal includes an acquirer configured to acquire tilt information on a tilt of the optical system, and a controller configured to control, as a shiftable unit is driven, the driving of the focus correction unit in accordance with the tilt information and vibration information on a vibration of the optical system or a shift drive amount of the shiftable unit, the shiftable unit being configured to shift in a direction orthogonal to the optical axis or a direction orthogonal to the normal in accordance with the vibration of the optical system for an image stabilization.
