Abstract
A flash modulation control apparatus in a camera having a photo-taking lens and a flash device mounted thereon comprises a photographing mode setting device for setting a photographing mode in which optimal exposure is obtained in conformity with an object, a divisional photometry device for dividing the object field into a plurality of areas, metering through the photo-taking lens light emitted from the flash device and reflected by the object, and outputting photometric values, a weighting device for determining an amount of weighting for each of the photometry areas of the divisional photometry device in conformity with the photographing mode set by the photographing mode setting device, and weighting each of the photometric values on the basis of the amount of weighting, and a light modulation control device for stopping the light emission of the flash device when the sum total of the weighted photometric values reaches a predetermined level.
