Barcode reader having calibration of scanner image brightness with multiple FOVs from a single sensor

Abstract:

A barcode reader having calibration of scanner image brightness with multiple FOVs from a single sensor is disclosed herein. An example barcode reader includes an imaging system having a first and second FOV. A first illumination system is configured to illuminate the first FOV. The first illumination system has a first tolerance range and a first characteristic. A second illumination system is configured to illuminate the second FOV. The second illumination system has a second tolerance range and a second characteristic. The first characteristic is established to achieve a minimum desired brightness at a beginning portion of the first tolerance range and a maximum desired brightness at an end portion of the first tolerance range. The second characteristic is established to achieve a minimum desired brightness at a beginning portion of the second tolerance range and a maximum desired brightness at an end portion of the second tolerance range.
