摘要： The apparatus of the present invention is provided with flashing device for effecting preliminary flashing and main flashing, a split photometry unit for metering reflected light from the area of the object field divided into a plurality of areas and outputting a photometric output for each of these areas, preliminary flashing control unit, a calculation unit and a main flashing control unit. The preliminary flashing control unit causes the flashing device to effect preliminary flashing prior to main flashing, and when in that case, at least one of the photometric outputs from the split photometry unit reaches a predetermined value, causes the flashing device to repeat the preliminary flashing while decreasing the quantity of emitted light thereof, and when the photometric outputs become null before the predetermined value is reached, causes the flashing device to stop the preliminary flashing. The calculation unit determines the divided areas which are not used for the flash limiting during the main flashing by the use of the photometric outputs and the quantity of emitted light during preliminary flashing at the last stage. The main flashing control unit controls the main flashing of the flashing device on the basis of the output of the calculation unit.
