Abstract
A shutter device includes: a first light shielding member disposed at a position further frontward relative to an image-capturing surface of an image sensor, which blocks a light flux from a subject by traveling along a predetermined direction of travel; and a second light shielding member disposed at a position further frontward relative to the image-capturing surface of the image sensor, which blocks the light flux by traveling along the direction of travel, wherein: at least either a length of a light shielding range of the first light shielding member, measured along the direction of travel, or a length of a light shielding range of the second light shielding member, measured along the direction of travel, is smaller than a length of the image-capturing surface along the direction of travel.
Claims11
A shutter device comprising:
- a first light shielding member that, by traveling along a first direction at a side toward a subject over an image-capturing surface of an image sensor, changes a state of each area on the image-capturing surface that is shielded from the side toward the subject into a state of the area that is opened to the side toward the subject;
- and
- a second light shielding member that, by traveling along the first direction at the side toward the subject over the image-capturing surface, changes the state of the area that is opened to the side toward the subject by traveling of the first light shielding member into a state of the area that is shielded from the side toward the subject, wherein:
- the first light shielding member is constituted so that the image-capturing surface has the area that is opened to the side toward the subject without being shielded from the side toward the subject by the first light shielding member in a traveling direction of the first light shielding member while the first light shielding member travels along the first direction at the side toward the subject over the image-capturing surface.

- the second light shielding member is constituted so that the image-capturing surface has the area that is opened at the side toward the subject without being shielded from the side toward the subject by the second light shielding member at an opposite side of a traveling direction of the second light shielding member while the second light shielding member travels along the first direction at the side toward the subject over the image-capturing surface.
