1. An imaging system comprising: a display system configured to display a sequential image for viewing; an image-acquisition system configured to determine a location of a head of a viewer from an image obtained by the image-acquisition system, the image-acquisition system further configured to track a positional change of the head of the viewer relative to the display system; and an image-generation logic configured to generate the sequential image, the sequential image being of a scene and including a motion parallax depiction of the scene based, at least in part, on the positional change of the head of the viewer relative to the display system, wherein the image-acquisition system is further configured to determine a number of faces from the image obtained by the image-acquisition system and the image-generation logic is further configured to at least adjust the generation of the sequential image depending on the number of faces.
