1. A control apparatus comprising:
at least one memory storing instructions; and
at least one processor that, upon execution—of the instructions, is configured to operate as:
a control unit configured to change an imaging range by controlling at least one of a pan, a tilt, and a zoom for an imaging unit to track a tracking target;
a setting unit configured to set a search area based on a range set by a user, a user operation for controlling the imaging range, or a past position of the tracking target;
an update unit configured to enlarge the search area to include a detected position of the tracking target outside the search area in a case where the tracking target is detected outside the search area; and
a determination unit configured to, in a case where tracking of the tracking target has failed, determine a zoom value for searching for the tracking target from a last captured image from which a subject is detected;
wherein, in the case where the tracking of the tracking target has failed, the control unit controls an imaging direction to search for the tracking target in the search area at the zoom value determined by the determination unit;
divides the search area into a plurality of blocks;
measures, for each of the plurality of blocks, a tracking-target presence time indicating a total time during which the tracking target has been present in each block;
determines a route for controlling the imaging range in the search area, the route being determined based on the tracking-target presence time for each of the blocks, so that blocks having a longer tracking-target presence time are searched first; and
controls the imaging range along the determined route.
