Systems and methods for implementing Z-buffer generation in a camera are disclosed. In an exemplary embodiment the method may comprise exposing a plurality of pixels on an image capture device to a modulated light signal reflected from different regions of a scene adjacent a camera after different delays. The method may also comprise correlating intensity of the modulated light signal received by the image capture device for each the different delays to determine a flight time of the modulated light signal. The method may also comprise generating a Z-buffer corresponding to the different regions of the scene based on the correlation.
