Fotometrieeinrichtung für eine Kamera

摘要

A photometry device has a normal light photometry sensor and a external light sensor. The normal light photometry sensor performs photometry with respect to an object. The external light sensor performs photometry with respect color components of the external light. An exposure amount of an object is determined based on an output of a normal light sensor. If a difference between the exposure values is greater than the predetermined value, a color judged in the colorimetry procedure is forcibly set to "colorless" and no substantial colorimetric compensation is performed. If the Bv difference is not greater than the predetermined value, the light source compensation data preliminary stored is used for the colorimetric compensation.
