An automatic light emission control system separately compensates the flashlight emission of each of a plurality of electronic flashes. A camera generates a first signal in synchronism with the opening of a shutter and generates a second signal when a TTL measured value of the reflected light from an object reaches a reference exposure set lower than a correct exposure. Each electronic flash connected to the camera includes an electronic flash unit, a photometry circuit for measuring its flashlight emission, and a compensation signal adjuster. The flashlight emission of the flash unit is initiated in response to the first signal and interrupted in response to the interrupt signal generated when an integrated emission amount measured by the photometry circuit reaches a desired flashlight emission amount determined in accordance with an intergrated emission amount measured up to the arrival of the second signal and the compensation signal amount.
