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 at which the region-of-interest is 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 at which the region-of-interest is lost in which the region of interest is not detected from the captured image, characterized in that the exposure correction value is a value indicating a relationship between the set region exposure target value before the time at which the region-of-interest is lost and the region-of-interest exposure target value before the time at which the region-of-interest is lost. 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;
