Abstract: An apparatus is described having an integrated two-dimensional image capture and three-dimensional time-of-flight depth capture system. The integrated two-dimensional image capture and three-dimensional time-of-flight depth capture system includes an illuminator to generate light for the time-of-flight depth capture system. The illuminator includes an array of light sources and a movable lens assembly. The movable lens assembly is to movably direct an emitted beam of the light to one of any of a plurality of locations within the illuminator's field of view to form an illuminated region of interest within the illuminator's field of view. The illuminated region of interest has a size that is smaller than the illuminator's field of view.

Abstract: An apparatus is described that includes an image sensor having timing and control circuitry and threshold circuitry. The timing and control circuitry is to generate signals to cause multiple transfers of charge from a photo-diode to a storage capacitor within a pixel cell during an image capture sequence. The threshold circuitry is to track the storage capacitor's voltage over the course of the multiple transfers and recognize when the storage capacitor's voltage reaches a threshold.
