PURPOSE: To inform easily a message whether the sum of respective corrected values attains to "1" or not to a photographer at the time of multiple exposure by displaying the sum of the correcting variables set up in respective photographings.
CONSTITUTION: An exposure correcting variable setting circuit is formed by counters CNT1, CNT2 and a correcting variable signal forming circuit is constituted by transistors Tr1WTr8 and constant current sources Q1WQ8. Current values corresponding to correcting variable information set up as the counted values of the CNT1, CNT2 are outputted by the Q1WQ8 and a correcting variable information signal VRF is set up on a shutter second controlling circuit SCC. A display device DCD4 displays a correcting variable integrated by an integrating circuit ACT. When the integrated value by the ACT exceeds "1", a signal discriminating circuit MCT sends a high level signal, and consequently, the displayed value of the DCD4 is turned on and off to alarm message that the exposed variable exceeds "1".
