<p>PURPOSE:To assure correct exposure by correcting aperture values with the signal indicating the control limit of a shutter second time and the aperture value. CONSTITUTION:When the shutter second time of a prescribed value exceeds a control limit, outputs are generated 27, 28, and when the prescribed aperture value is in a control limit, an output is generated 35. When the respective outputs are all inputted, the aperture value to be controlled is corrected 46 from the prescribed value to the aperture value that gives correct exposure with respect to the shutter second time of the control limit.</p> |
