Abstract
An apparatus includes time of flight single-photon avalanche diode (ToF SPAD) circuitry. The ToF SPAD circuitry generates indications of distance between the apparatus and an object within a field of view. A processor receives the indications of distance and controls at least one image sensor, such as a camera, to capture at least one image based on at least one indication of distance. The processor determines whether an image is a true representation of an expected object by comparing multiple indications of distance associated with the object to an expected object distance profile and comparing the image to at least one expected object image.
