ABSTRACT:
A color gradient analyzer having a photo-electric convertor and a rotational filter having a plurality of optical color filters provides the information of an object. The output of said photo-electric convertor is switched according to the color of the color filter of said rotational filter in front of the photo-electric convertor, and is recorded on a recorder. A white ball is also provided for the calibration of the apparatus. Thus the apparatus can operate and provide a color information on a real-time basis.
