A driving control apparatus is configured to control a driving unit that moves relative to each other a vibrator that is excited to vibrate by applying a first driving signal and a second driving signal that have a phase difference with each other, and a contact member that contacts the vibrator. The driving control apparatus includes a first control unit configured to control the phase difference, and a second control unit configured to control a voltage amplitude of each of the first driving signal and the second driving signal. The second control unit controls the voltage amplitude so that a change rate of the voltage amplitude increases as an absolute value of the phase difference decreases.

Driving control apparatus, image pickup apparatus, and control method

A control apparatus includes a processor is configured to function as an information acquisition unit configured to acquire object size information from image data by a first method and a second method in continuous imaging, and an imaging control unit configured to perform an exposure while performing follow-up drive of an optical system so as to reduce a difference between the object size information and target size information.

Control apparatus, control method, and computer-readable storage medium

Control apparatus, imaging apparatus, control method, and storage medium

An image stabilization apparatus which is capable of properly correcting for image blurring while at the same time obtaining correct focus evaluation values. Based on a detected shake, a vibration isolation lens is moved in a direction different from a direction of an optical axis of a shooting optical system. While a focus lens is being moved in the direction of the optical axis, focus evaluation values are obtained based on an image pickup signal obtained by taking an image of a subject. A method to control the focus lens is determined according to whether or not the focus lens is being moved, and with the determined method, movement of the focus lens in the direction of the optical axis is controlled based on an amount by which the vibration isolation lens has moved.

Image stabilization apparatus that corrects for image blurring, control method therefor, image pickup apparatus, and storage medium

An image pickup apparatus includes a determination unit configured to determine, based on luminance information of an object, a shooting condition from among a plurality of shooting conditions containing information on an aperture value and a shutter speed, a control unit configured to perform control so as to sequentially shoot a plurality of images having in-focus positions different from each other while discretely moving a focus lens by each moving amount depending on the aperture value, and an image synthesizing unit configured to synthesize the plurality of images, and the determination unit determines the shooting condition from among the plurality of shooting conditions so as to reduce a time for shooting the plurality of images.

Image pickup apparatus, method of controlling image pickup apparatus, and non-transitory computer-readable storage medium

A lens control device which is capable of controlling lens positions such that an in-focus state of an object image can be maintained even when a variable power lens is positioned outside a normal zoom range from a wide-angle end to a telephoto end. A flash memory stores a positional relationship between the variable power lens and a focus lens, on an object distance-by-object distance basis. A system controller controls the movement of the focus lens by calculating the in-focus position of the focus lens with respect to the position of the variable power lens based on the positional relationship stored in the flash memory when the variable power lens is moved to a position outside the normal zoom range defined in the positional relationship stored in the flash memory.
