Abstract
An interval between a pinhole and a pinhole is set to a first interval at which a degree of superimposition of subject images captured through the corresponding pinholes falls within a predetermined range when an image of a subject located at a distance less than a predetermined distance from the multi-pinhole camera is captured. An interval between the pinhole and a pinhole is set to a second interval narrower than the first interval at which a degree of superimposition of subject images captured through the corresponding pinholes falls within a predetermined range when an image of the subject located at a distance equal to or more than the predetermined distance from the multi-pinhole camera is captured.
Claims7
A multi-pinhole camera, comprising:
- an image sensor;
- and
- a mask disposed between a light receiving surface of the image sensor and a subject and having a mask pattern provided with multiple pinholes including a first pinhole, a second pinhole adjacent to the first pinhole, and a third pinhole adjacent to the second pinhole,
- wherein an interval between the first pinhole and the second pinhole is set to a first interval,
- the first interval allowing a degree of superimposition of two subject images captured through the first pinhole and the second pinhole to be within a predetermined range when the subject located at a distance less than a predetermined distance from the multi-pinhole camera is captured by the multi-pinhole camera,
- an interval between the second pinhole and the third pinhole is set to a second interval narrower than the first interval,
- the second interval allowing a degree of superimposition of two subject images captured through the second pinhole and the third pinhole to be within the predetermined range when the subject located at a distance equal to or more than the predetermined distance from the multi-pinhole camera is captured by the multi-pinhole camera,
- when the multi-pinhole camera captures an image of the subject located at the distance equal to or more than the predetermined distance from the multi-pinhole camera, a degree of superimposition of two subject images captured through the first pinhole and the second pinhole is outside the predetermined range, and
- when the multi-pinhole camera captures an image of the subject located at the distance less than the predetermined distance from the multi-pinhole camera, a degree of superimposition of two subject images captured through the second pinhole and the third pinhole is outside the predetermined range.
