Image sensing apparatus and control method therefor

An image sensing apparatus comprising:

• an image sensing unit having one or more image sensing regions adapted to receive an object image via said lens and accumulate the received image as an electric charge;
• a mechanical shutter which includes a first curtain and second curtain adapted to travel so as to shield the one or more image sensing regions against light;
• a scanning unit adapted to perform scanning for sequentially starting the accumulation of the electric charge for each one or more image sensing region of said image sensing unit;
• a controller adapted to control the scanning for starting the accumulation of the electric charge and the travel of said mechanical shutter, so as to implement a first curtain and second curtain of a shutter;
• and
• a switching unit adapted to switch the first curtain of the shutter from an electronic first curtain to said first curtain of said mechanical shutter on the basis of at least one of:
• the type of the lens and information on the lens.

A control method for an image sensing apparatus which comprises:

• an image sensing unit adapted to receive an object image via a lens and accumulate the received image as an electric charge;
• a mechanical shutter unit adapted to travel so as to shield an image sensing region of the image sensing unit against light;
• a scanning unit adapted to perform scanning for sequentially starting the accumulation of the electric charge for each image sensing region of the image sensing unit;
• and
• a control unit adapted to control the accumulation start scanning of the scanning unit and the travel of a shutter of the mechanical shutter unit, so as to implement a first curtain and second curtain of a shutter, the method comprising:
• changing a maximum shutter speed on the basis of at least one of:
• the type of the lens and information on the lens.
