Systems and methods for implementing Z-buffer generation in a camera are disclosed. In an exemplary embodiment the method may comprise actuating a light sensor after various delays to receive a plurality of modulated light signals reflected from different regions of a scene adjacent a camera. The method may also include determining distance information for the different regions of the scene based on brightness values for the plurality of modulated light signals reflected from the scene for the various delays. The method may also include storing the distance information in a Z-buffer at the camera.
