Abstract
An indicia reading terminal for reading of a decodable indicia is provided wherein the indicia reading terminal includes an image sensor integrated circuit comprising an image sensor having a plurality of pixels; a memory for storing image data, and a unit for processing the image data for attempting to decode decodable indicia represented in the image data; and an optical system, including a lens assembly and at least a first aperture and a second aperture, the second aperture being smaller than the first aperture. The lens assembly comprises one or more lens elements. The first aperture is disposed in the lens assembly, and the second aperture is disposed at a distal end of the optical system, adjacent to the lens assembly.
Claims18
An indicia reading terminal for reading of a decodable indicia, said indicia reading terminal comprising:
- an image sensor integrated circuit comprising an image sensor having a plurality of pixels;
- a memory for storing image data, and a processor for processing the image data for attempting to decode decodable indicia represented in the image data;
- and
- an optical system, comprising:
- a housing;
- a lens assembly within the housing comprising one or more lens elements and a first aperture;
- and
- a second aperture at a distal end of the optical system adjacent the housing of the lens assembly;
- wherein the first aperture and the second aperture are disposed along an imaging axis;
- wherein the second aperture is smaller than the first aperture;
- and
- wherein the optical system's distal end is away from the image sensor.
An indicia reading terminal, comprising:
- an image sensor integrated circuit comprising an image sensor;
- a memory for storing image data generated by the image sensor;
- a processor for processing the image data for attempting to decode decodable indicia represented in the image data;
- and
- an optical system comprising:
- a housing;
- a lens assembly within the housing comprising one or more lens elements;
- a first aperture disposed in the lens assembly;
- and
- a second aperture that is smaller than the first aperture,
- wherein the lens assembly, the first aperture, and the second aperture are disposed along an imaging axis;
- wherein the first aperture is disposed between the image sensor and the second aperture;
- wherein the second aperture is disposed at a distal end of the optical system away from the image sensor;
- and
- wherein the second aperture is adjacent to the housing.
