PURPOSE:To attain proper color temperature compensation by arranging plural pairs of color detectors in or at the back side of a photographing lens and adding the color temperature of the incident light from an object and the surrounding of the object and a distance setting value to the object to a discriminating element for color temperature compensation. CONSTITUTION:Color detectors 31, 32 are arranged at the back side of the photograhing lens 36 and on the lower circumference. The reflected light itself from the object and the surrounding of object is added to the color temperature detector 31 by the color detectors 31, 32 and a color temperature signal is obtained. This color temperature signal is added to color temperature compensators 34, 35, and applied to a variable gain amplifier 12 of a red signal and a variable gain amplifier 13 of a blue signal to adjust the gain and to obtain the proper color temperature compensation. |
