发明名称 PHOTOMETRY DEVICE FOR CAMERA
摘要 PURPOSE: To provide a photometry device for camera capable of confirming a variation amount in exposure caused by multipaLtem photometry, in a photometry device for camera executing the multipattern photometry. CONSTITUTION: This photometry device for camera is provided with a photometry means 30 having photometry elements for the photometry of plural places in the photographing range, a photometric value calculating means 43 calculating an effective photometric value by weighing addition corresponding to a selected photometry mode to each photometric value obtained by the photometry by each of these photometry elements, a deviation calculating means 45 fetching the effective photometric value by a reference value calculating means 44 calculating a reference photometric value by prescribed weighing addition set in advance to each photometric value obtained bv the photometry by each photometry element and the photometric value calculating means 43 and the reference photometric value by the reference value calculating means 44 and calculating a deviation in the logarithmic value of the fetched value and a display means 26 for displaying the deviation calculated by the deviation calculating means 45.
