ABSTRACT:
A camera system includes: a light emitting unit that performs a main emission of light in which during photography a photographic subject is illuminated with a first light having a first color temperature, and a preparatory emission of light in which the photographic subject is illuminated with a second light having a second color temperature before photography; an imaging element that outputs an image capture signal; a calculator that calculates an amount of the first light by the light emitting unit, based upon the image capture signal output during the preparatory emission of light; a corrector that corrects the calculated amount of the first light, based upon a color temperature difference between the first color temperature and the second color temperature; and a controller that controls the light emitting unit to perform the main emission of light at the amount of the first light after correction by the corrector.
