Abstract: A code reader comprises a first imager and a second imager configured to capture an image with different field of views, a first illuminator and a second illuminator configured to project a different illumination pattern, and a processor operably coupled to the imagers and the illuminators. The processor configured to activate the first imager and the first illuminator as a receiver pair responsive to detecting a first condition, activate the second imager and the second illuminator as a receiver pair responsive to detecting a second condition, and decode an optical code using an image captured by the selected receiver pair.

Abstract: An optical scanner captures a plurality of images from a plurality of image-capture devices. In response to the activation signal, an evaluation phase is executed, and in response to the evaluation phase, an acquisition phase is executed. In the evaluation phase, a first set of images is captured and processed to produce a virtual frame comprising a plurality of regions, with each region containing a reduced-data image frame that is based on a corresponding one of the plurality of images. Also in the evaluation phase, attributes of each of the plurality regions of the virtual frame are assessed according to first predefined criteria, and operational parameters for the acquisition phase are set based on a result of the assessment. In the acquisition phase, a second set of at least one image is captured via at least one of the plurality of image-capture devices according to the set of operational parameters.

Abstract: A code reader may include a light source configured to illuminate a target area in which items are to be located for reading machine-readable indicia associated with the items, an image sensor configured to capture an image of the target area, an illumination drive circuit in electrical communication with the light source, and an image capture circuit. The image capture circuit may be configured to (i) enable and disable the image sensor to capture an image of the target area during the high illumination and a portion(s) of the low illumination of the target area, and (ii) read an image captured by the image sensor. The illumination drive signals may cause the illumination drive circuit to generate a high illumination drive signal to cause the light source to produce a high illumination, and generate a low illumination drive current to cause said light source to produce a low illumination.

Abstract: Systems and methods for providing additional processing capabilities related to machine-readable symbols. A data collection system (100) may include a scan engine (102), auxiliary image processor (104), auxiliary visualizer (106), and host system (108). The scan engine may output decoded information obtained from a representation of a machine-readable symbol captured by a two-dimensional image processor. The scan engine may also output a set of images related to the machine-readable symbol and an object associated with the machine-readable symbol, in which the set of images may form a streaming set of images or streaming video. The set of images may be used by the auxiliary image processor to obtain further information about the machine-readable symbol and/or associated object, such as OCR or DWM information. The set of images may be stored and made accessible by the auxiliary visualizer. The host system may synchronize a display of the images and decoded data output by the scan engine.

Abstract: An optical scanner determines ranging to a subject using a localization phase in which a series of image frames is received which collectively contains an aimer spot captured as a reflection off of a surface of the subject. The captured aimer spot is temporally modulated according to a modulation pattern, and the series of image frames is processed to discriminate the aimer spot based on the modulation pattern to determine a probable location of the aimer spot within at least one of the image frames of the series. A triangulation phase follows in which the probable location of the aimer spot is processed to produce the ranging determination. In an optional implementation, an assessment is made whether that probable location of the aimer spot is within a plausible location based on different device-specific positional offsets in image frames captured by different ones of the plurality of image-capture devices.
