发明名称 PHOTOMETRIC DEVICE OF CAMERA
摘要 PROBLEM TO BE SOLVED: To obtain a photometric device using a storage type photometric element, where storage for photometry is hardly interrupted and an extact photometric value is obtained even in the case the duration of mirror-down at the time of consecutive photographing is short. SOLUTION: This device is provided with a photometric circuit 10 performing the photometry of field by using the storage type photometric element, a storage control circuit 13 controlling the start and the finish of the storage of the photometric element, a feeding mode setting part 16 capable of setting the feeding mode of film at least to a high speed mode where photographing interval is short and a low speed mode where the photographing interval is long, and a gain decision part deciding the output gain of the photometric circuit based on output from the feeding mode setting part.
