Abstract
According to an aspect, an imaging device includes: a planar optical sensor comprising a plurality of photodiodes; a pinhole plate stacked in a first direction with respect to the optical sensor and provided with a plurality of pinholes; a storage circuit configured to store therein a first image indicating a light-dark pattern captured by the optical sensor in a state where a point light source faces the pinhole plate at a predetermined distance; and a processing circuit configured to perform image processing to generate a third image by performing an image restoration calculation process based on the first image and a second image that is obtained by capturing a subject using the optical sensor through the pinholes of the pinhole plate.

An imaging device comprising:
- a planar optical sensor comprising a plurality of photodiodes;
- a pinhole plate stacked in a first direction with respect to the optical sensor and provided with a plurality of pinholes;
- a storage circuit configured to store therein a first image indicating a light-dark pattern captured by the optical sensor in a state where a point light source faces the pinhole plate at a predetermined distance;
- and
- a processing circuit configured to perform image processing to generate a third image by performing an image restoration calculation process based on the first image and a second image that is obtained by imaging a subject using the optical sensor through the pinholes of the pinhole plate.
An imaging device comprising:
- a planar optical sensor comprising a plurality of photodiodes;
- a code mask sheet stacked in a first direction with respect to the optical sensor and provided with a plurality of code patterns and a light-blocking area located outside the code patterns;
- a storage circuit configured to store therein a first image indicating a light-dark pattern captured by the optical sensor in a state where a point light source faces the code mask sheet at a predetermined distance;
- and
- a processing circuit configured to perform image processing to generate a third image by performing an image restoration calculation process based on the first image and a second image that is obtained by imaging a subject using the optical sensor through the code patterns of the code mask sheet, wherein
- each of the code patterns includes light-transmitting portions and light-blocking portions.
