  • Patent number: 11172133
    Abstract: A subject detection unit of an imaging apparatus detects a subject image from an image. An automatic zoom control unit performs zoom control according to a size of a subject detected by the subject detection unit. The automatic zoom control unit automatically selects a specific composition among a plurality of compositions and sets a reference size of the subject used to control a zoom magnification based on the selected composition and the size and position of the detected subject. A process of determining a scene using information including a detection result by the subject detection unit, a composition selection process is performed on the determination scene, and one composition is selected from a composition of upper body of the subject, a composition of whole body, a composition of a subject face, and a composition of multiple people.

  • Patent number: 9992421
    Abstract: An image pickup apparatus includes a movement detector detecting movement of the apparatus, a subject detector detecting a subject, a setting unit setting a mode for controlling a zoom operation which is enabled as a first mode or second mode, and a controller controlling the zoom operation based on the enabled mode. In the first mode, the controller controls the zoom operation based on at least one of position or size of the detected subject. In the second mode, the controller performs a first zoom operation for changing a zoom magnification to a wide-angle side when a movement amount of the apparatus is a first amount larger than a predetermined amount and performs a second zoom operation for changing the zoom magnification to a telephoto side when a movement amount of the apparatus detected after execution of the first zoom operation is a second amount smaller than the predetermined amount.
