Exposure control device in a camera

摘要

An exposure control device in a camera comprises a focus detection device for calculating a plurality of defocus amounts corresponding to a plurality of focus detection areas, a weight producing device for producing a plurality of weights corresponding to the plurality of focus detection areas on the basis of the plurality of defocus amounts, a light metering device for light-metering a plurality of light metering areas at least partly overlapping with the plurality of focus detection areas and producing a plurality of light metering outputs, and an exposure amount calculating device for calculating a proper exposure amount on the basis of the plurality of weights and the plurality of light metering outputs.
