An exposure control device in a camera comprising: focus detection means for detecting a focus state with respect to each of a plurality of focus detection areas and producing a corresponding plurality of defocus amounts; weight producing means for producing a plurality of weights corresponding to said plurality of focus detection areas on the basis of said plurality of defocus amounts, said weight producing means being capable of producing at least three different weights; light metering means for light-metering a plurality of light metering areas at least partly overlapping with said plurality of focus detection areas and producing a plurality of light metering outputs; and exposure amount calculating means for calculating a proper exposure amount on the basis of said plurality of weights and said plurality of light metering outputs; wherein for two defocus amounts having the same absolute value, and indicative, respectively, of the fact that an object image is on the object side relative to a film surface and of the fact that an object image is on the camera side relative to the film surface, said weight producing means produces two different weights, respectively.
