1. An imaging control apparatus comprising:
an exposure control unit configured to perform exposure control on a basis of information of a region of interest detected from a captured image by a region-of-interest detection unit,
wherein the exposure control unit is configured to:
perform exposure control in which a region-of-interest exposure target value calculated on a basis of a region-of-interest photometric value obtained from a first photometric region including at least a region of interest in an input frame is set as an exposure control value, in a case where the region of interest is detected from the captured image;
perform exposure control in which a set region exposure target value calculated on a basis of a set region photometric value obtained from a second photometric region determined in advance in the input frame is set as the exposure control value, in a case where the region of interest is not detected from the captured image; and
obtain an exposure correction value on a basis of the region-of-interest exposure target value before a time of region-of-interest lost, and then perform exposure control with the exposure control value obtained by correcting the set region exposure target value with the exposure correction value, in a predetermined period in which the region of interest is not detected continuously from the time of the region-of-interest lost in which the region of interest is not detected from the captured image.
