Abstract
An imaging engine for an indicia reader that includes a dual-purposed housing is disclosed. The housing is configured to provide support and alignment for the imaging engine's optical modules. In addition, the housing includes an integrated optical structure to focus or project light to or from the various optical modules.
Claims20
An imaging engine for an indicia reader, comprising:
- an imaging module for capturing an image of the imaging engine's field of view;
- an aiming module for projecting a visible aligning pattern onto a target to provide information regarding the imaging engine's field of view and to facilitate alignment of the image captured by the imaging module;
- an illuminating module for projecting light onto the target to illuminate the imaging engine's field of view;
- and
- a housing configured to provide support and alignment for the imaging module, the aiming module, and the illuminating module, wherein at least a portion of the housing is (i) optically transparent and (ii) shaped to form an integrated optical structure for focusing light to/from the imaging module, the aiming module, and/or the illumination module.
2 more elements
An indicia-reading imaging engine for integration within a hand-held mobile computing device, the indicia-reading imaging engine comprising:
- an imaging module for capturing an image of the imaging engine's field of view, the imaging module comprising an image sensor and one or more imaging-module lenses;
- an aiming module for projecting a visible aligning pattern onto a target via an aiming-module light source to provide information regarding the imaging engine's field of view and to facilitate alignment of the image captured by the imaging module;
- an illuminating module for projecting light onto a target via an illuminating module light source to highlight the imaging engine's field of view;
- and
- an optically transparent housing (i) configured to provide support and alignment for the imaging module, the aiming module, and the illuminating module and (ii) shaped to form optical-structures that correspond to the imaging module, the aiming module, and the illuminating module, respectively;
- wherein one of the housing's optical-structures is a housing imaging lens, and the one or more imaging-module lenses and the housing imaging lens form a lens group to render an image onto the image sensor;
- wherein one of the housing's optical-structures is a housing aiming lens that is positioned in front of the aiming-module aperture in order to project the aiming-module aperture's image onto the target;
- and
- wherein one of the optical-structures is a housing illuminating lens that is positioned in front of the illuminating-module light source in order to provide uniform illumination within the imaging engine's field of view.
