In one example, an imaging apparatus includes an exposure controller that performs exposure control on the basis of information of a region of interest detected from a captured image by a region-of-interest detector. The exposure controller performs different exposure control for different cases, such as whether the region of interest is detected from the captured image. It obtains an exposure correction value on the basis of the region-of-interest exposure target value before a time of region-of-interest lost, and then performs 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.
