PURPOSE:To easily determine a structure diagram by immediately driving an electronic view finder even if a 1st stroke of a release button is not executed when a self-timer photographing mode is set up. CONSTITUTION:When a switch S3 for setting up the self-timer photographing mode is turned on, the output of an inverter 4 is turned from an 'L' level to an 'H' level, an SR flip flop (FF)5 for storing the self-timer photographing mode is set up, its Q output is turned to the 'H' level and the -Q output is turned to the 'L' level. When the -Q output of the SR FF5 is turned from the 'H' level to the 'L' level, the reset of a counter 12 is released and the counter 12 starts to count up the passage of time from the setting of the self- timer photographing mode and an object at that time is displayed on the electronic view finder 11. Even if the 1st stroke of the release button is not executed, the finder 11 can be immediately driven and a structure diagram can be easily determined.
