Abstract
A photographic device eliminates photometric errors that occur in photometry, obtains a more accurate exposure, and shortens the time required for photometry. The device includes an orientation position detector and photographic mode setter, which outputs photographic conditions based on a set photographic mode. A photometer divides the subject field into multiple regions and analyzes the light. An exposure calculator calculates the exposure value based on the output of the photometer. A memory stores weighing coefficients corresponding to multiple light brightness patterns. A tilt switch position orientation detector determines the position of the camera. A selector selects the weighing coefficients from the memory, based on the photographic mode setting component output and the position of the camera. A frequency analyzer then analyzes the output frequency of the photometer. A re-calculator re-calculates the exposure value based on the result of the frequency analyzer and the selection of the selector.
