ABSTRACT:
An image pickup apparatus including a memory for storing color temperature data concerning an illuminating apparatus, a colorimetric circuit for measuring a color temperature of ambient light, an amplification circuit for controlling balance of color signals obtained from an image pickup element, and a controller for comparing the color temperature of the ambient light obtained from the colorimetric circuit with the color temperature data concerning the illumination apparatus and for controlling the amplification gain by the amplification circuit according to the comparison result to adjust the white balance, and further including a detecting circuit for detecting that the color temperature of the ambient light is not the color temperature along the black body radiation, wherein, depending on the detection of the detecting circuit, illumination is made by the illuminating apparatus to thereby take the white balance matched with the color temperature data concerning the illuminating apparatus.
