One Sensor Near Far Solution To Minimize FOV Mismatch And Aiming Offsets
Apparatuses, systems, and methods for providing a one sensor near far solution to minimize field of view mismatch and aiming offsets are provided. For example, an indicia reader utilizing dual optics may include an engine comprising a near field imaging optic and a far field imaging optic that split an imaging sensor array and a aimer; wherein the near field imaging optic, the far field imaging optic, and the aimer are configured in a triangular arrangement to minimize the field of mismatch and aiming offsets. In some embodiments, the far field imaging optic may be configured to utilize a two or more prisms to provide a periscope configuration.
SYSTEMS, APPARATUSES, METHODS, AND COMPUTER PROGRAM PRODUCTS FOR AUTOMATIC SWITCHING OF OBJECT DETECTION MODES
Systems, apparatuses, methods, and computer products for automatic switching of object detection modes are provided, including for switching of object detection modes of an indicia reader. For example, an indicia reader of a barcode scanner may be in an environment where a background is detected by one or more infrared object detection modes. The detection of the background but not an object with an indicia may result in the indicia reader continuously seeing the background. In accordance with the present disclosure, an indicia reader may automatically switch between a plurality of object detection modes, which may include deactivating one or more components, modules, and/or circuitry of the indicia reader.
MULTI-SENSOR SYSTEM WITH PICTURE-IN-PICTURE IMAGE OUTPUT
The disclosure relates to systems and methods for combining images captured by at least two image sensors of a multi-sensor image system into a single image frame for analysis, where the combined image frame includes the image data captured by each sensor. The captured images may include image data for an optical code on an item being processed. The multi-sensor system includes a decoding unit operable to analyze the combined image frame and decode the optical codes from one or both images contained within the combined image frame.
Mobile imaging barcode scanner
Performance and size improvements in indicia readers are disclosed. The improvements provide for the integration of a barcode image scanner in a size restricted mobile computer device, such as a slim mobile data terminal or a smart mobile phone, and provide for the ability for the indicia reader to read direct product marking (DPM) type of barcodes. The improvements include the incorporation of an illumination module or bar that can generate dark field and bright field illumination. The illumination module can be designed to match the front end of a smart mobile phone and maintain a low profile design. Symmetric arranged multi-field, multi-color illuminator with close-up corrective lens and near coaxial aimer optics provide illumination and aiming support for the DPM scanning. The improvements allow the indicia reader, assembled in a slim mobile data terminal, to read direct product marking (DPM) type of barcodes.
Laser scanning code symbol reading system providing control over length of laser scan line projected onto a scanned object using dynamic range-dependent scan angle control
Method of and system for reading bar code symbols using a hand-supportable laser scanning bar code symbol reading system supporting an improved level control over the length of laser scan lines projected onto scanned objects, at any instant in time, in a manner dependent the detected location, distance or range of the scanned object in the scanning field of the system during system operation. The length characteristics of the laser scan line are controlled by setting the laser scan sweep angle as a function of detected or estimated distance or range of the object from the system. In the illustrative embodiment, the laser scan sweep angle is controlled by supplying a drive current to the scanning mechanism, as a function of detected or estimated distance or range of the object from the scanning system.
Code symbol reading system having adaptive autofocus
A system for reading code symbols includes an imaging subsystem that includes a focusing module and an image processor. The image processor selects an initial, predicted focal distance for the imaging subsystem's focusing module with respect to a code symbol. The focal distance for each successfully decoded code symbol is stored in memory, and a weighted average of a pre-selected number of memorized focal distances is used to calculate the next initial, predicted focal distance.
DIGITAL IMAGE CAPTURING METHOD AND ELECTRONIC DEVICE FOR DIGITAL IMAGE CAPTURING
An electronic device and a method are provided for digital image capturing including activating a digital camera to capture an image, when an optical code, especially a barcode is detected. Advantageously, the invention provides to zoom-out a zooming means of the digital camera before capturing the image and after detecting the optical code.
Extended depth of field in imaging machine-readable symbol reader using image side telecentric lens
Systems and methods for providing multiple image fields or regions on a single, two-dimensional imaging sensor array of a data reader. A single sensor array may be divided into two or more imaging regions each of which may be used to render a separate view of an overall read volume. An image-side telecentric optical system may be utilized to divide the sensor array into the two or more imaging regions. A thin, high refractive index focal element (e.g., optical glass) may be positioned over at least one of the two or more imaging regions to provide multiple focus positions using a single telecentric optical system and a single sensor array. The multiple imaging regions may be used to capture images from different regions, and/or may be used produce a longer depth of field by combining overlapping depths of field of the multiple imaging regions.
APPARATUS AND METHOD FOR READING BARCODES AND RECORDING MEDIUM
A barcode reading apparatus has a scanner unit for reading barcodes and a processor for controlling whole operation of the apparatus. The barcode reading apparatus judges whether a distance between a operation unit for receiving an instruction to be given by a user and an operating body such as the finger of the user falls with in a prescribed range, and starts up and brings the scanner unit to a standby state, when it is determined that the distance between the operation unit and the operating body falls with in the prescribed range, and waits for an instruction of making the scanner unit start reading barcodes.
OPTICAL SCANNING FOR LINE-OF-SIGHT COMMUNICATIONS TO OPTICAL TAGS
An optical communication device can address these and other issues by utilizing a system and method in which an optical device emits a series of laser pulses that trace a spiral path over a coverage area. Each laser pulse containing a packet of information modulated at a relatively rate to help mitigate adverse effects from device movements, scintillation, and the like. The beam width of the laser, speed of the scan (along the spiral path), and number of laser pulses can be configured such that corresponding response pulses (e.g., retro-modulated pulses) received from an illuminated tag within the coverage may have a variety of different amplitudes, increasing the likelihood that at least one of the response pulses will have power characteristics that facilitate a proper decoding of the response pulse.
