1. An imaging apparatus capable of performing shooting with flash light emitted by a flash device, the imaging apparatus comprising: an imaging unit configured to capture an image of an object to output image data; and a charging control unit configured to perform charging control of a capacitor configured to accumulate energy for performing flash emission by the flash device, wherein the charging control unit, in a case where shooting with flash light emitted by the flash device is performed among a plurality of shooting operations for acquiring a plurality of pieces of image data to be used for image combining processing, performs the charging control so that charging of the capacitor is not performed until the last shooting of the plurality of shooting operations for acquiring a plurality of pieces of image data to be used for the image combining processing is finished.
