A reading apparatus according to an embodiment includes a captured-image reading section, an article detecting section, an object recognizing section, and a code reading section. The captured-image reading section reads, from an imaging apparatus that captures a captured image associated with distance information indicating distances to articles, the captured image associated with the distance information. The article detecting section detects images of articles in a preset predetermined imaging region in the captured image. The object recognizing section performs, based on the distance information, object recognition processing of an object, the object being an article closest from the imaging apparatus among the articles. The code reading section performs, based on the distance information, if a distance between the object and the imaging apparatus is equal to or smaller than a predetermined distance, code reading processing for detecting a code symbol from the predetermined imaging region and reading code information from the code symbol.

Systems and methods for user choice of barcode scanning ranges are provided. This is achieved through the identification of a predetermined pixel-per-module threshold range. The pixel-per-module of a barcode being read by a reader is compared to the predetermined pixel-per-module threshold range, and a successful decode of the barcode is carried out only if the pixel-per-module of the barcode falls within the predetermined range. Thus, a user may select a desired reading distance range such that barcodes within a working distance range may not generate successful decodes if such barcodes are outside of the desired reading distance range.

Near and far imagers image close-in and far-out targets over relatively wider and relatively narrower imaging fields of view, respectively. An aiming assembly directs to a target a visible aiming light pattern having an aiming light spot and a pair of collinear aiming light lines. The aiming light spot is substantially centered between the aiming light lines. A controller determines a distance to the target based on a position of the aiming light spot in the imaging field of view of a default one of the imagers, selects at least one of the imagers based on the determined distance, and enables both the close-in and the far-out targets to be positioned substantially entirely within the respective imaging field of view of the selected imager.

An imaging assembly for capturing at least one object appearing in a field of view (FOV) is provided that includes an image capturing system, a controller operatively coupled to the image capturing system to control operation thereof, and a processor operatively coupled to the controller. The image capturing system is adapted to capture an image having at least one sub-frame and is further adapted to obtain distance information of the object. The processor analyzes the image to determine a brightness value of at least a portion of the image and analyzes the distance information of the object to determine a distance value from the imaging assembly to the object. The processor further determines an illumination characteristic based on the brightness value and the distance value.

The present application provides a method and apparatus for presenting a graphic code. The method includes: after detecting that a graphic code page is invoked, starting a front-facing image capture module of a current device to perform image capturing; performing image recognition on a captured image, and if the captured image includes a pre-configured feature of a code scanning module, calculating an offset distance between the code scanning module and a current presentation location of a graphic code; and calculating a target presentation location based on the offset distance, and presenting the graphic code at the target presentation location. Based on the method provided in the present application, a location of a graphic code can be adapted automatically, and a user does not need to perform alignment, thereby improving user experience.

This invention provides a vision system, typically having at least two imaging systems/image sensors that enable a multi-function unit. The first imaging system, typically a standard, on-axis optical configuration can be used for long distances and larger feature sets and the second imaging system is typically an extended-depth of focus/field (DOF) configuration. This second imaging system allows reading of smaller feature sets/objects and/or at shorter distances. The reading range of an overall (e.g.) ID-code-reading vison system is extended and relatively small objects can be accurately imaged. The extended-DOF imaging system sensor can be positioned with its longest dimension in the vertical axis. The system can allow vision system processes to compute the distance from the vision system to the object to generate an autofocus setting for variable optics in the standard imaging system. An aimer can project structured light onto the object surface around the system optical axis.

In an embodiment, the present invention is an imaging engine including: a first imaging assembly having a first FOV; a second imaging assembly having a second FOV; and an aiming assembly configured to emit an aiming light pattern, the aiming light pattern including a first portion and a second portion, the first portion configured to correlate with the first FOV, the second portion configured to correlate with the second FOV, wherein the aiming light pattern is configured such that a combined power of any part of the aiming light pattern encompassed by a 7 mrad cone, as measured from the aiming assembly, is less than or equal to 1 mW, and the total combined power of the entire aiming light pattern is greater than 1 mW.

A handheld optical information reading device is provided which comprises a housing, a grip arranged on the housing, an image capture device, an illuminator, an illumination controller, an imaging controller, an image processor, and a reader. The image capture device captures an image including a symbol. The illuminator includes lighting devices around the periphery of an optical axis of the image capture device. The illumination controller controls the illuminator to selectively successively light up the lighting devices based on a predetermined order whereby irradiating a symbol with light in different illumination directions with respect to the optical axis. The imaging controller controls the image capture device to capture images of the symbol every when the lighting devices are selectively successively lighted up. The image processor creates an outline image of the symbol based on the captured images. The reader reads the symbol based on the created outline image.
