ABSTRACT:
A photometric value compensating device corrects the influence on the photometric value of a mark or character superimposed in the finder field of a camera when the finder field is finely divided for photo metering and makes it possible to always obtain the proper exposure value. The photometric value compensating device includes a finely divided photo metering device that divides the photographic field into multiple areas and measures the light intensity or brightness in each area and transmits information based on the measured light intensity as a photometric brightness value. A photographic information display device superimposes photographic information inside the finder field. A correction area determining device determines the photometric areas for which photometric value correction is necessary based on the brightness of the photographic information displayed in the photometric areas of the finely divided photo metering device. A correction device calculates a corrected brightness value based on the photometric brightness values obtained from photometric areas determined by the correction area determining device.
