ZOOM CONTROL DEVICE, IMAGING APPARATUS, CONTROL METHOD OF ZOOM CONTROL DEVICE, AND RECORDING MEDIUM

摘要

A subject detection unit of an imaging apparatus detects a subject image from an image. An automatic zoom control unit determines whether the subject detection unit detects the subject image in a specific region and performs first control such that a zoom magnification is controlled on a telephoto side based on a determination result when the subject image is not detected in the specific region. The automatic zoom control unit changes the first control to second control when the subject detection unit detects the subject image in the specific region, and controls the zoom magnification based on a reference size and a sequentially detected size of the subject image.

主权项

1. A zoom control device comprising:
a subject detection unit configured to detect a subject image from an image; a determination unit configured to determine whether the subject detection unit detects the subject image in a specific region of the image; and a control unit configured to perform control of zoom magnification, wherein, in the control of the zoom magnification, the control unit performs first control such that the zoom magnification is controlled on a telephoto side when the determination unit determines that the subject image is not detected in the specific region, and the control unit performs second control such that the zoom magnification is controlled based on a reference size and a size of the subject image sequentially detected by the subject detection unit when the determination unit determines that the subject image is detected in the specific region.
