METHOD OF CONTROLLING ILLUMINATION PULSES TO INCREASE DYNAMIC RANGE IN IMAGER BARCODE SCANNER |
摘要 |
A method for controlling a workstation includes the following: (1) energizing a first illuminator to illuminate a first subfield of view with a first illumination pulse and subsequently energizing the first illuminator to illuminate the first subfield of view with a second illumination pulse; (2) exposing the array of photosensitive elements in the imaging sensor for a first sensor-exposure time and subsequently exposing the array of photosensitive elements in the imaging sensor for a second sensor-exposure time; and (3) processing an image captured by the imaging sensor to decode a barcode in the image. The first illumination pulse overlaps with the first sensor-exposure time for a first overlapped-pulse-duration, and the second illumination pulse overlaps with the second sensor-exposure time for a second overlapped-pulse-duration. The first overlapped-pulse-duration is different from the second overlapped-pulse-duration. |
