ABSTRACT:
A camera capable of white balance correction (WBC) of this invention has an image pickup optical system, an image sensor for receiving light from an object, a three-primary-color (3-color) detection section for detecting 3-color signals based on the image sensor output, a matrix processing section for calculating 2-color difference signals from the 3-color signals, a visible-light brightness detection section for detecting visible-light brightness by the output from the 3-color detection section or by a photometric section, an infrared-light detection section for detecting the lightness of infrared-light, and an artificial-light detection section for calculating the ratio of artificial light and natural-light. A correction range for performing the WBC is obtained based on the ratio of artificial-light and natural-light computed by the artificial-light detection section, and the WBC is performed when the 2-color difference signals are within the correction range.
