1. A system configured to adjust the perceived depth of 3D content in response to a viewer input control signal, the system comprising: a content source configured to provide an input left stereoscopic image and an input right stereoscopic image; a disparity estimator configured to receive the input left stereoscopic image and the input right stereoscopic image, to detect disparities between the input left stereoscopic image and the input right stereoscopic image, and to generate a disparities array; processing circuitry configured to fill in occlusion areas associated with the disparities array and to apply a scale factor to the detected disparities to thereby generate a scaled disparities array, wherein the scale factor is based on the viewer input control signal; and a warping engine configured to receive the scaled disparities array and to generate therefrom an output left stereoscopic image and an output right stereoscopic image, wherein the output left stereoscopic image and the output right stereoscopic image have a different perceived depth than the input left stereoscopic image and the input right stereoscopic image when perceived by the viewer.
