Abstract
A camera assembly for generating differential images for a local area. The camera assembly includes a sensor and a controller. The sensor images at least a portion of a local area and includes a plurality of augmented pixels. Each augmented pixel has at least a first gate with a first local storage location and a second gate with a second local storage location. An exposure interval of the sensor is divided into intervals. The first local storage location stores first image data during a first of the intervals, and the second local storage location stores second image data during a second of the intervals. The controller determines, for each augmented pixel, a difference between the first image data and the second image data. The controller then reads out the difference for each augmented pixel as a differential image of the portion of the local area.
