Abstract: An image based code reader comprises an image sensor. The image sensor is configured to acquire an image of a code. Additionally, the image based code reader includes a lens configured to project an image scene including the code onto the image sensor, the lens comprising a variable optical power that controls a focus distance of the image based code reader. The image based code reader further includes a processor operatively coupled to the image sensor and the lens. The processor is configured to acquire the image of the code using only pixels located within a region of interest of the sensor, and a size of the region of interest is selected based on the focus distance of the reader.

Abstract: This invention provides a vision system camera, and associated methods of operation, having a multi-core processor, high-speed, high-resolution imager, FOVE, auto-focus lens and imager-connected pre-processor to pre-process image data provides the acquisition and processing speed, as well as the image resolution that are highly desirable in a wide range of applications. This arrangement effectively scans objects that require a wide field of view, vary in size and move relatively quickly with respect to the system field of view. This vision system provides a physical package with a wide variety of physical interconnections to support various options and control functions. The package effectively dissipates internally generated heat by arranging components to optimize heat transfer to the ambient environment and includes dissipating structure (e.g. fins) to facilitate such transfer. The system also enables a wide range of multi-core processes to optimize and load-balance both image processing and system operation (i.e. auto-regulation tasks).

Abstract: An illumination system is provided for an optical system that includes an imaging device for acquiring an image of a target, for decoding of a symbol or other analysis. The illumination system can include a first light source configured to provide illumination of a first wavelength, a second light source configured to provide illumination of a second wavelength that is different from the first wavelength. The light sources can be controlled for operations that include: illuminating the target with the first and second light sources simultaneously for acquisition of the image of the target; and altering an illumination output of at least one of the first light source or the second light source, while maintaining non-zero illumination output for at least one of the first light source or the second light source, to indicate a status of the optical system.

Abstract: This invention provides a single-camera vision system, typically for use in logistics applications, that allows for adjustment of the camera viewing angle to accommodate a wide range of object heights and associated widths moving relative to an imaged scene with constant magnification. The camera assembly employs an image sensor that is more particularly suited to such applications, with an aspect (height-to-width) ratio of approximately 1:4 to 1:8. The camera assembly includes a distance sensor to determine the distance to the top of each object. The camera assembly employs a zoom lens that can change at relatively high speed (e.g.

Abstract: This invention provides a vision system with an exchangeable illumination assembly that allows for increased versatility in the type and configuration of illumination supplied to the system without altering the underlying optics, sensor, vision processor, or the associated housing. The vision system housing includes a front plate that optionally includes a plurality of mounting bases for accepting different types of lenses, and a connector that allows removable interconnection with the illustrative illumination assembly. The illumination assembly includes a cover that is light transmissive. The cover encloses an illumination component that can include a plurality of lighting elements that surround an aperture through which received light rays from the imaged scene pass through to the lens. The arrangement of lighting elements is highly variable and the user can be supplied with an illumination assembly that best suits its needs without need to change the vision system processor, sensor or housing.
