Abstract: Passive autofocusing is used in image acquisition devices (e.g., machine-readable symbol readers, cameras), and can be employed with shutter and/or event-based image sensors. An aimer pointer is easily detected in images, and one or more characteristics characterized at various focus positions of the optics. A size of a characteristic dimension and/or shape of the aimer pointer and/or a measure of sharpness of the aimer pointer is used to determine which image, and hence focus position, results in an optimized or even optimum (i.e., best) focus. The image acquisition system is then configured accordingly. Measuring aimer pointer size is typically less computationally intensive than conventional approaches. Use of a laser beam to produce the aimer pointer usually requires lower exposure time than other approaches. Image data can advantageously be windowed using a relatively small region of interest (ROI) based on a known aimer pointer position.

Abstract: An optical scanner device includes at least one image capture device and a transmitter of at least one aimer beam. The scanner device determines ranging to a subject using the at least one aimer beam projected to reflect off of a surface of the subject, and detects a position of the aimer-beam reflection within an image frame captured by the image-capture device, the position being a primary indicator of a distance to the subject from the optical scanner device. A secondary indicator of the distance to the subject within the image frame in combination with the first indicator is used to help detect the aimer beam reflection against noise and detect an occurrence of an optical misalignment with possible self-correction of calibration after such misalignment.

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: A system and method for providing animated feedback for a barcode scanning system may include receiving image data from a camera, processing the image data, detecting a machine-readable indicia in the image data, and attempting to decode the machine-readable indicia. In response to successfully decoding the machine-readable indicia, displaying a first animation indicative of successfully decoding the machine-readable indicia. Otherwise, in response to not successfully decoding the machine-readable indicia, displaying a second animation indicative of not successfully decoding the machine-readable indicia.
