Imaging apparatus, method for controlling imaging apparatus, and storage medium, for underwater flash photography

摘要

An imaging apparatus configured to perform white balance correction on an image captured with flash emission includes an object region specifying unit configured to specify an object region irradiated with flash by the flash emission, a first white balance coefficient calculation unit configured to calculate a first white balance coefficient based on a light amount of flash for the object region specified by the object region specifying unit and a light amount of external light, an object distance calculation unit configured to calculate an object distance when imaging with the flash emission includes underwater photography, and a second white balance coefficient calculation unit configured to calculate a second white balance coefficient from the first white balance coefficient and the object distance calculated by the object distance calculation unit when the object distance calculated by the object distance calculation unit is equal to or less than a predetermined distance.

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.
