发明名称 CAMERA SYSTEM PROVIDED WITH COLORIMETRIC FUNCTION AND ITS USING METHOD
摘要 PROBLEM TO BE SOLVED: To obtain a camera system provided with a colorimetric function capable of appropriately using a colorimetric method intended by a photographer by measuring color information by appropriately using a reflector reflecting light from field and making it incident on a photometry part or a diffusing plate diffusing the light from the field and making it incident on the photometry part. SOLUTION: By using the standard white reflector 41, the field light from a light source is reflected to perform colorimetry. By attaching the milky-white diffusing plate 42 to the front surface of a camera body 51, the light from the light source is made incident so as to perform the colorimetry. Furthermore, by attaching the milky-white diffusing plate 42 to the front surface of an interchangeable lens 52, the light from the light source is made incident so as to perform the colorimetry. Thus, the colorimetric method intended by the photogapher is easily executed by appropriately using the reflector 41 or the diffusing plate 42. Therefore, when a subject is separated from a photographing position, the photographer need not go to the place of the subject, so that operability is improved. The color information with which the color of a lens is tinged is obtained, so that the behavior range of the photographer is extended further.
