Abstract
There is provided an imaging device capable of improving image quality of a reconstructed image in lensless imaging, and a method of operating the imaging device. A mask that is provided at a preceding stage of an imaging element and modulates incident light is a mask including a pattern defined by a non-binary URA. The present disclosure can be applied to a lensless camera.
Claims9
An imaging device comprising:
- a mask that includes a plurality of optical elements having different transmittances, the plurality of optical elements being arranged in a pattern defined by non-binary uniformly redundant arrays (URA), wherein the mask is configured to modulate incident light into modulated light by transmitting the incident light through the plurality of optical elements;
- an imaging element configured to capture a modulated image including the modulated light transmitted through the mask;
- and
- circuitry configured to reconstruct an image corresponding to the incident light based on the modulated image,
- wherein a one-dimensional array of a predetermined length constituting the pattern defined by the non-binary URA is generated based on a multiplication result of one-dimensional arrays defined by non-binary URA of different lengths that are mutually prime.

A method of operating an imaging device,
- the imaging device including
- a mask that includes a plurality of optical elements having different transmittances, the plurality of optical elements being arranged in a pattern defined by non-binary uniformly redundant arrays (URA), wherein the mask is configured to modulate incident light into modulated light by transmitting the incident light through the plurality of optical elements,
- an imaging element configured to capture a modulated image including the modulated light transmitted through the mask, and
- circuitry configured to reconstruct an image corresponding to the incident light based on the modulated image, and
- the method comprising:
- modulating the incident light into modulated light by the mask transmitting the incident light through a plurality of optical elements having different transmittances and being arranged in the pattern defined by the non-binary URA;
- capturing by the imaging element a modulated image including the modulated light transmitted through the mask;
- and
- reconstructing an image corresponding to the incident light based on the modulated image,
- wherein a one-dimensional array of a predetermined length constituting the pattern defined by the non-binary URA is generated based on a multiplication result of one-dimensional arrays defined by non-binary URA of different lengths that are mutually prime.
