A flashlight control device and an operating method thereof are provided. The present invention utilizes the light-tuning circuit to optics-electricity converse the reflected light (from the target object) to the exposure voltage. When the exposure voltage is higher than the reference voltage, the flashlight stops light-emission because it means the amount of the light-emission amount is adequate. When the exposure voltage is lower than the reference voltage, the flashlight continues to emit the incident light because the amount of the light-emission is not adequate. Hence, occurrence of the over-exposure or under-exposure problems can be effectively eliminated.
