Document Type and Number:
Japanese Patent JP5927565
Kind Code:
B2
Abstract:
An imaging apparatus includes an imaging sensor operable to capture a subject image and output image information, a gain setting unit operable to set a value of an output signal amplification gain according to a value of ISO sensitivity for amplifying the image information output from the imaging sensor, a determination unit operable to determine a value of white balance gain to be used for white balance correction according to the value of the output signal amplification gain set by the gain setting unit, and a white balance correcting unit operable to perform white balance correction on the image information output from the imaging sensor based on the value of the output signal amplification gain set by the setting unit and the value of the white balance gain determined by the determination unit.
