Abstract

Systems and methods for optical imaging are disclosed. An electronic device for imaging an input object includes a display comprising a sensing surface and an array of display pixels. The electronic device also includes a processing system communicatively coupled to the display, the processing system configured to: selectively illuminate one or more of the display pixels according to a pattern; acquire image data, from one or more detector pixels of the display, of the input object in contact with the sensing surface, wherein the image data corresponds to light from the illuminated display pixels that is reflected at the sensing surface of the display; and process an image of the input object from the image data based upon the pattern.
