Image sensing apparatus with electronic shutter function and mechanical shutter function, and image sensing method |
摘要 |
An image sensing apparatus having an electronic shutter for controlling the charge accumulation time of an image sensing element and a mechanical shutter for releasing/shielding an optical path to the image sensing element includes an electronic shutter mode of controlling the image sensing time mainly by the electronic shutter and a mechanical shutter mode of controlling the image sensing time mainly by the mechanical shutter. In the electronic shutter mode, the operations of the electronic and mechanical shutters are controlled to overlap each other, and a charge reading period of the image sensing element and part of a release operation period of the mechanical shutter are controlled to overlap each other.
