Abstract
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.
Claims23
A method for glare reduction, the method being implemented by a graphical code reader, the method comprising:
- illuminating a target area using a plurality of light sources;
- capturing images of the target area using at least one image sensor;
- determining that glare is present in at least one captured image;
- determining glare information that indicates which of the light sources are responsible for the glare;
- and
- taking corrective action to reduce the glare in subsequent images based on the glare information that is determined.
A graphical code reader that is configured to perform glare reduction, comprising:
- a plurality of light sources that are configured to illuminate a target area;
- at least one image sensor that is configured to capture images of the target area;
- a glare detector that is configured to determine that glare is present in at least one captured image and to determine glare information that indicates which of the light sources are responsible for the glare;
- and
- an illumination controller that is configured to take corrective action to reduce the glare in subsequent images based on the glare information that is determined.
A graphical code reader that is configured to perform glare reduction, comprising:
- means for illuminating a target area using a plurality of light sources;
- means for capturing images of the target area using at least one image sensor;
- means for determining that glare is present in at least one captured image;
- means for determining glare information that indicates which of the light sources are responsible for the glare;
- and
- means for taking corrective action to reduce the glare in subsequent images based on the glare information that is determined.
