Abstract
Systems and methods for optical imaging are disclosed. An optical sensing system, including a display, an optical sensor, and a processor communicatively coupled to the display and the optical sensor is provided. The processor is configured to execute an input object image capture method. The method determines that an input object is proximate to an optical sensing region of the display, and in response to determining that an input object is proximate to the sensing region of the display, the optical sensing system illuminates the sensing region with an illumination sequence. The illumination sequence includes a cue mark sequence preceding an illumination pattern, where the cue mark sequence contains information about the illumination pattern.
