In an exposure control device for a camera wherein exposure is controlled in accordance with the scene object light reflected from the surfaces of a leading shutter curtain and a film, the error in exposure control due to the difference in reflecting power between the surfaces of the film and the leading shutter curtain is corrected on the basis of an integral value of the difference between the output of the light measuring circuit and the output of a delay circuit which delays the output of said light measuring circuit by a predetermined period of time.
