Virtual reality system using super-resolution

Displaying video in an HMD may include introducing unperceived noise to the video frame signal in order to enhance dynamic range. For example, each of a viewer's left and right eyes have a field of view (FOV) corresponding to a portion of pixels shown on the HMD. For each of these portions of p...

Zusammenfassung:Displaying video in an HMD may include introducing unperceived noise to the video frame signal in order to enhance dynamic range. For example, each of a viewer's left and right eyes have a field of view (FOV) corresponding to a portion of pixels shown on the HMD. For each of these portions of pixels, the VR system may combine a noise signal (e.g., zero-mean Gaussian white noise) with the video signals corresponding to each of the portions of pixels. The introduction of such noise may improve the dynamic range of the viewer. Further, in some implementations, the noise signal that is combined with the left video signal may be slightly different from the noise signal that is combined with the right video signal. Such slightly different noise signals may provide further improvement to the image seen by the viewer due to binocular summation.
