A method for glare reduction may be implemented by a graphical code reader. The method may include illuminating a target area using a plurality of light sources. The method may also include capturing images of the target area using at least one image sensor. The method may also include determining that glare is present in at least one captured image. The method may also include determining glare information that indicates which of the light sources are responsible for the glare. The method may further include taking corrective action to reduce the glare in subsequent images based on the glare information that is determined.

Graphical code readers that are configured for glare reduction

A graphical code reader may include means for capturing an image frame in accordance with a rolling shutter technique, and means for changing illumination while the image frame is being captured in order to perform glare correction. The graphical code reader may also include means for detecting characteristics of glare in a previously captured image frame.

A system for decoding machine-readable graphical codes is provided. The system includes a graphical code reading device configured to read a graphical code and generate reference encoded source data. The reference encoded source data includes a first reference identifier and a second portion. The system also includes a computing device in electronic communication with the graphical code reading device. The computing device also includes a reference decoder configured to effect conversion of the reference encoded source data into source data. The source data includes first affiliated data in place of the first reference identifier. The first affiliated data may be longer in length than the first reference identifier. The source data also includes the second portion. The computing device also includes a software application configured to use the source data.

A method for glare reduction may be implemented by a graphical code reader. The method may include illuminating a target area using a plurality of light sources. The method may also include capturing images of the target area using at least one image sensor that operates in accordance with a rolling shutter technique. The method may also include determining that glare is present in at least one captured image. The method may also include determining which of the light sources are responsible for the glare. The method may further include taking corrective action to reduce the glare in subsequent images based on which of the light sources are responsible for the glare.

The present invention provides a novel optical reader device and method for calibrating the device. The device executes a calibration module that locates the actual coordinates for a targeting symbol in a captured image. The coordinates are stored as calibration coordinates in the memory. During normal operation of the reader device, the stored calibration coordinates are used to locate a target, such as a bar code. In order to locate the targeting symbol, the calibration module may overlay a template on clusters that may be the targeting symbol. A reasonable accurate comparison identifies the cluster as the targeting symbol. Alternatively, the calibration module may approach a cluster from four frames of the image and identify the cluster's tangents and perimeter. Geometrical calculations are used to identify the center of an identified targeting symbol.

A graphical code reader that provides sequenced illumination for glare reduction may include a plurality of light sources that illuminate a target area. The graphical code reader may also include at least one image sensor that captures an image of the target area using a rolling shutter technique. The graphical code reader may also include an illumination controller that sequences illumination of the light sources so that the light sources that are providing the normal component of the illumination to an active portion of the target area are turned off, and so that the light sources that are not providing the normal component of the illumination to the active portion of the target area are turned on.

A method for adaptively varying resolutions of captured images may include capturing images and processing the captured images. The method may also include determining brightness information about the captured images. The method may also include varying the resolutions of the captured images based on the brightness information that is determined about the captured images. The method may also include determining intended brightness information corresponding to the captured images, and the resolutions of the captured images may be varied based on the intended brightness information as well as the brightness information.

Systems and methods for concurrent image capture and decoding of graphical codes are disclosed. In an exemplary method disclosed herein, a first image is captured by an image capture component in a graphical code reader. The first image is processed by a decoding component. Processing the first image involves searching for a graphical code within the first image and attempting to decode the graphical code. A second image is then captured by the image capture component while the first image is being processed by the decoding component.
