Automatic tuning of scanner lighting

摘要

Various embodiments herein each include devices, system, methods, and software for automatic scanner lighting tuning. One method embodiment includes determining a distance from a scanning surface to a surface of an item presented for scanning, determining an illumination setting based on the determined distance, and illuminating a scanning field according to the determined setting. Another embodiment is a scanner including a scanning module with a scanning surface imaged by an imaging device and a lighting module including at least one adjustable lighting element that illuminates according a received illumination setting. The scanner further includes a distance determining module that determines a distance between the scanning surface and a presented item and a lighting controller that receives a determined distance from the distance determining module, determines the illumination setting based on the determined distance, and provides the illumination command to the lighting module.
