Title: IMAGE SENSOR WITH RANGE AND LIGHT-LEVEL DETECTION
Abstract:
Systems and methods for selectively illuminating objects located within the field-of-view of an image sensor used to capture images in a machine-readable symbol reader. In an active illuminated reading mode, a light source illuminates objects as the image sensor captures images. In a self-illuminated object reading mode, used to capture images of smartphone, tablet, or other self-illuminating displays, the image sensor captures images without the light source illuminating the objects. The machine-readable symbol reader transitions between the two modes based upon distance and light-level measurements taken of the various objects that are within the field-of-view of the image sensor.
