Abstract:
A shutter apparatus mounted in an image sensing apparatus, the shutter apparatus comprising: a blade member configured to open/close an opening through which light from an object passes, and control an aperture area of the opening; and a driving unit capable of first and second driving controls, the first driving control driving the blade member to serve as a stop, and the second driving control driving the blade member to serve as a shutter, wherein when the object is captured by an image sensor, the driving unit temporarily drives the blade member in an opening direction from a first position, to which the blade member is driven in a closing direction to serve as a stop, and then activates the blade member to a fully closing position.
