A control circuit for a camera having an auxiliary light source for preventing a red-eye phenomenon separately from an electronic flash light source. When the red-eye preventing mode for emitting light from the auxiliary light source is selected, the battery is checked after the ordinary judging level is switched over to a higher judging level. At ordinary time, the voltage of the battery is checked while applying a dummy current to a predetermined driving portion of said camera, and when the red-eye preventing mode is selected, the voltage of the battery voltage is checked while applying the dummy current to another driving portion in addition to the predetermined driving portion. Thus, auxiliary electronic flashing is secured and the battery is used effectively. By utilizing the auxiliary light source for controlling both preliminary electronic flashing for preventing the red-eye phenomenon and auxiliary electronic flashing for passive autofocusing, the auxiliary light source is effectively used.
