Imaging apparatus and method, and device

An imaging apparatus, comprising an imaging element with an imaging surface of a spherical structure, wherein angles between all parts of the spherical imaging surface and light emitted by an image source at an intersection of the imaging surface are 90°, and a plurality of imaging units are distributed on the imaging surface,

• wherein the imaging units are arranged on the imaging surface, and satisfy at least one of the following conditions:
• a) arranged in a manner of spiral lines, a spacing between every two of the imaging units on a same spiral line is equal and is equal to a spacing between adjacent two of the spiral lines, and when there are a plurality of spiral lines on the imaging surface on which the imaging units are arranged in a manner of the spiral lines, a spacing between every two of the plurality of spiral lines is equal and is equal to the spacing between every two of the imaging units;
• the spacing herein refers to a spacing along the imaging surface;
• b) distributed on the imaging surface in an equally spaced manner without using any point, line, or surface as a reference object;
• and
• the imaging units refer to photosensitive units on a photosensitive surface of a camera image sensor, display pixels of a display screen, or image pixels of an image.
