摘要： A shooting control apparatus obtains image data from an imaging unit that obtains the image data based on light from an imaging optical system and then detects an object and an orientation of the detected object from the image data. The apparatus controls a shooting direction of the imaging unit by controlling rotational driving of the imaging unit so that a position of the object in a field of view of the imaging unit changes based on the orientation of the object. The apparatus controls the shooting direction, in a case where the object faces in a first direction, so that a distance between an edge of the field of view on a first direction side and the object to be greater than a distance therebetween in a case where the object faces forward.

摘要： A shooting control apparatus obtains image data from an imaging unit that obtains the image data based on light from an imaging optical system, and detects an object from the image data. The apparatus controls rotational driving of the imaging unit and a zoom mechanism included in the imaging optical system based on a result of detection of the object by determining a target zoom position and a shooting direction of the imaging unit. The apparatus determines the target zoom position and the shooting direction so that the object falls within a partial region of a field of view of the imaging unit including a center of the field of view, based on a size and position of the object.

摘要： A control device configured to track a subject by controlling a correcting lens so that the subject is moved to a target position of a photographed image. The control device performs feedback control so that a difference between a position of the subject and a target position of the subject in the photographed image becomes small. The control device detects a photographing condition and changes a degree of tracking of the subject by changing a control gain in the feedback control based on the detected photographing condition.

摘要： An image pickup apparatus is provided with a shake correction unit that corrects image shake of an image that can arise from shake such as camera shake and a driver thereof. An angular velocimeter detects an angular velocity of shake, and an accelerometer detects acceleration of the shake. A CPU acquires an angular velocity detection signal and an acceleration detection signal, and then computes a first parallel shake amount that is shake in the direction orthogonal to the optical axis of an imaging optical system. A velocity computation unit computes a second parallel shake amount by combining the acceleration detection signal and the first parallel shake amount. The driver drives the shake correction unit based on the second parallel shake amount to correct shake.
