DARK EXPOSURE CONTROL DEVICE |
摘要 |
A dark exposure control device comprises a dark exposure performing processor, an aperture-stop, and an aperture-stop driving processor. The dark exposure performing processor detects an image signal generated by an imaging device while the shutter is closed. The aperture-stop adjusts the amount of light incident on the imaging device. The aperture-stop driving processor adjusts the opening degree of the aperture-stop to smaller than the opening degree set for a main exposure while the dark exposure performing processor is operated. |
