Exposure control device for a camera in flash photography

An exposure control device for a camera in flash photography comprising;

• first means for measuring light from a central area of an object field;
• second means for measuring light from another area surrounding the central area;
• means for comparing a light measuring output from said first measuring means with that from said second measuring means to determine a difference therebetween;
• means for controlling exposure in response to said second measuring means to cause an over-exposure by a given value when the difference determined by said comparing means exceeds a predetermined level;
• means for directing a flash light emission;
• and
• means for integrating light reflected from the object field upon the flash light emission to stop the flash light emission when the integrated light reaches a predetermined level.

An exposure control device for a camera in flash photography comprising;

• means for investigating focus to a portion of an object field;
• means for adjusting focus in response to said investigating means;
• means for disabling said adjusting means once said investigating means decides an in-focus condition even if said investigating means detects an out-of-focus condition afterward;
• means for directing a flash light emission;
• means for integrating light reflected from the object field upon the flash light emission;
• means for generating a modifying signal in response to said investigating means upon exposure;
• and
• means for causing the flash light emission to stop in response to said integrating means and said modifying signal.
