IMAGE PICK-UP APPARATUS TO PICK UP STATIC IMAGE |
摘要 |
An image pick-up apparatus that is capable of correcting shading due to a closing travel operation of a shutter by a simple process. An image pick-up device picks up the image formed. A shutter unit opens and closes a substantially rectangular aperture corresponding to image pick-up area of the image pick-up device by means of a plurality of rotating shutter blades. The shutter blades travel in mutually opposite directions perpendicular to a long side of the aperture while keeping edges of the shutter blades facing the aperture are parallel to the long side so that edge portions that cover a center area of the aperture start shading the aperture before edge portions that cover four corner areas of the aperture start shading the aperture.
