Control device for a camera shutter and a control method therefor

A control device for a camera shutter, the control device comprising:

• diaphragm value setting means for setting a predetermined diaphragm value of the shutter;
• means for controlling the set diaphragm value of the shutter in a stepwise manner;
• exposure value setting means for setting an exposure value of the shutter;
• storing means for storing an opening size of the shutter, output timings of signals for controlling opening and closing operations of the shutter, and an exposure value of the shutter corresponding to the diaphragm value set in a stepwise manner;
• and
• control means for calculating the output timings of the signals for controlling the opening and closing operations of the shutter on the basis of the exposure value of the shutter outputted from the exposure value setting means, and controlling the opening and closing operations of the shutter on the basis of the results of the calculation.

A method for controlling the opening and closing operations for a camera shutter, comprising the steps of:

• setting a predetermined diaphragm value of the shutter;
• setting an exposure value of the shutter;
• storing an opening size of the shutter, output timings of signals for controlling opening and closing operations of the shutter, and an exposure value of the shutter corresponding to the set diaphragm value;
• calculating the output timings of the signals for controlling the opening and closing operations of the shutter on the basis of the exposure value of the shutter;
• and
• controlling the opening and closing operations of the shutter on the basis of the results of the calculation.
