摘要: A method of scanning and reading indicia off a display is disclosed. The may utilize light sensor mobile device to improve the quality indicia, such as barcode, display. scanner illuminates in order increase backlight intensity obtain high contrast image on then ceases illumination scan without specular reflection caused by illumination. In one embodiment, for period time achieve maximum level brightness that capable emitting before ceasing another detects whether change greater than predefined
