Shutter device and image-capturing device

A shutter device comprising:

• a substrate member at which an opening through which a light flux from a subject is guided to an image sensor is formed;
• a first light shielding member that blocks the light flux by passing across the opening in a direction of travel along a plane parallel to an image-capturing surface of the image sensor;
• and
• a second light shielding member that blocks the light flux by passing across the opening in the direction of travel along a plane parallel to the image-capturing surface of the image sensor, 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 opening along the direction of travel.

A shutter device comprising:

• a substrate member at which an opening through which a light flux from a subject is guided to an image sensor is formed;
• a first light shielding member that blocks the light flux by passing across the opening further on a side on which the light flux advances as incident light relative to the image sensor;
• and
• a second light shielding member that blocks the light flux by passing across the opening at a later time point than the first light shielding member, further on the side on which the light flux advances as incident light relative to the image sensor, wherein:
• the first light shielding member partially shields the opening from light at a position at which the first light shielding member starts traveling.

• the second light shielding member partially shields the opening from light at a position at which travel of the second light shielding member ends.

An image-capturing device, comprising:

• the image sensor having a plurality of pixels arrayed in a matrix pattern;
• a first light shielding member disposed at a position further frontward relative to an image-capturing surface of the image sensor, which blocks a light flux from a subject by traveling along a predetermined direction of travel;
• 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;
• and
• a control unit that controls a reset and an image-capturing signal read executed in each of pixel rows at the image sensor, wherein:
• the control unit engages the image sensor in the reset executed in each of pixel rows in correspondence to travel of the first light shielding member along the direction of travel, or engages the image sensor in the image-capturing signal read executed in each of pixel rows in correspondence to travel of the second light shielding member along the direction of travel.
