Abstract: An automatic flash amount control apparatus of camera, which can avoid over-exposure of a subject to be controlled in flash amount even if the subject to be illuminated occupies only a small portion of photo-taking screen, executes photo-metering of a field to be photographed while dividing the field into a plurality of first metering regions without flashing of a flashing device and meters an optical flux emitted by the flashing device and then reflected by the field to be photographed while dividing the flux into a plurality of second metering regions. The apparatus separates the second metering regions into two groups, one of which is to contribute to and the other of which is not to contribute to flash amount control, with correspondence to respective results of metering of the first metering regions.

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.
