CONTROL APPARATUS, METHOD OF CONTROLLING IMAGE SENSING DEVICE, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM

摘要

A recording unit records a size of a tracking target that appears in a sensed video that is sensed by the image sensing device. A search unit, when from a state in which the tracking target can be detected from the sensed video, a state in which it cannot be detected is entered, obtains a predicted size of the tracking target in the sensed video based on the size recorded by the recording unit for a case of zooming out at a predetermined scaling factor. Then if the predicted size is larger than a predetermined size, the search unit zooms out by the predetermined scaling factor, and then searches for the tracking target in the sensed video after the zoom out.

1. A control apparatus that controls an image sensing device for tracking and sensing a tracking target, the apparatus comprising:
a recording unit configured to record a size of a tracking target that appears in a sensed video that is sensed by the image sensing device; and a search unit configured to, when from a state in which the tracking target can be detected from the sensed video, a state in which the tracking target cannot be detected is entered, obtain a predicted size of the tracking target in the sensed video based on the size recorded by the recording unit for a case of zooming out at a predetermined scaling factor, and if the predicted size is larger than a predetermined size, zoom out by the predetermined scaling factor, and then search for the tracking target in the sensed video after the zoom out.
