摘要： An automatic control type electronic flash apparatus comprises means for emitting flashlight and flashlight emission stopping means. The stopping means receives the flashlight emitted by the flashlight emitting means and reflected by an object to be photographed and stops the emission of the flashlight by the flashlight emitting means when a quantity of the flashlight received reaches a predetermined value. The flash unit includes integrating means for integrating a current corresponding to the flashlight emitted by the flashlight emitting means in place of the flashlight reflected by the object and comparing means. The comparing means compares an integrated value from the integrating means with a reference value and generates a first output when the integrated value is smaller than the reference value and a second output when the integrated value is greater than the reference value. The flash unit includes indicating means for showing an over-exposure in response to the first output.
