发明名称 PHOTOMETRIC DEVICE FOR CAMERA
摘要 PROBLEM TO BE SOLVED: To provide a photometric device by which a photometric error due to the manufacturing error of a camera is highly accurately corrected. SOLUTION: A photometric arithmetic part 43 calculates the luminance of a field based on the lens data of an attached lens and a photometric data outputted by a photometric element 6. An individual data storing part 44 stores a data corresponding to a deviation from the design specification of a photometric optical system 40 at a manufacturing stage for each camera. A photometric correcting/calculating part 45 calculates a luminance correcting amount based on a lens data and an individual data by using an operation expression obtained by previously analyzing a relation between the deviation value and the luminance correcting amount and corrects the luminance of the field.
