Claim Text:
1. An imaging apparatus configured to perform white balance correction on an image captured underwater with flash emission, the imaging apparatus comprising: a memory device configured to load instruction into at least one processor, and the at least one processor, wherein the at least one processor is configured to: specify an object region irradiated with flash by the flash emission; calculate a first white balance coefficient based on a light amount of flash and external light for the specified object region; calculate an object distance from the imaging apparatus; calculate a correction value to be used to correct the first white balance coefficient based on the calculated object distance; and calculate a second white balance coefficient by correcting the first white balance coefficient with the correction value, wherein the correction value is calculated so that a correction amount of the first white balance coefficient increases as the distance of the region excluding a main object from the imaging apparatus becomes smaller than the calculated distance of the main object from the imaging apparatus.
