    Abstract: A device includes a time-of-flight ranging sensor configured to transmit optical pulse signals and to receive return optical pulse signals. The time-of-flight ranging sensor processes the return optical pulse signals to sense distances to a plurality of objects and to generate a confidence value indicating whether one of the plurality of objects has a highly reflective surface. The time-of-flight sensor generates a range estimation signal including a plurality of sensed distances and the confidence value. The image capture device includes autofocusing circuitry coupled to the time-of-flight sensor to receive the range estimation signal and configured to control focusing based upon the sensed distances responsive to the confidence value indicating none of the plurality of objects has a highly reflective surface. The autofocusing circuitry controls focusing independent of the sensed distances responsive to the confidence value indicating one of the objects has a highly reflective surface.

    Abstract: An electronic device includes a ranging light source and a reflected light detector. A logic circuit causes the ranging light source to emit ranging light at a target. Reflected light from the target is detected using the reflected light detector, with the reflected light being a portion of the ranging light that reflects from the target back toward the reflected light detector. An intensity of the reflected light is determined using the reflected light detector. A distance to the target is determined based upon time elapsed between activating the ranging light source and detecting the reflected ranging light. Reflectance of the target is calculated, based upon the intensity of the reflected light and the distance to the target.
