US 12,217,371 B1 · Selective depth analysis

Abstract

Techniques are disclosed, whereby graphical information for a first image frame to be rendered is obtained at a first device, the graphical information comprising at least depth information for at least a portion of the pixels within the first image frame. Next, a regional depth value may be determined for a region of pixels in the first image frame. Next, the region of pixels may be coded as either a “skipped” region or a “non-skipped” region based, at least in part, on the determined regional depth value for the region of pixels. Finally, if the region of pixels is coded as a non-skipped region, a representation of the region of pixels may be rendered and composited with any other graphical content, as desired, to a display of the first device; whereas, if the region of pixels is coded as a skipped region, the first device may avoid rendering the region.

Dependent claims

A selective graphical composition method, comprising:

obtaining, at a first device, graphical information for a first image frame, wherein the graphical information comprises at least depth information and color information for at least a portion of pixels within the first image frame;
determining a regional depth value for a region of pixels in the first image frame based, at least in part, on the depth information for the pixels within the region of pixels;
coding the region of pixels as either a skipped region or a non-skipped region based, at least in part, on the determined regional depth value for the region of pixels and a determination of whether color information for any of the pixels within the region of pixels contains a non-default value;
if the region of pixels is coded as a non-skipped region, compositing a representation of the region of pixels into the first image frame;
and
if the region of pixels is coded as a skipped region, avoid compositing a representation of the region of pixels into the first image frame.

determine a regional depth value for a region pixels in the first image frame;
code the region of pixels as either a skipped region or a non-skipped region based, at least in part, on the determined regional depth value for the region of pixels and a determination of whether color information for any of the pixels within the region of pixels contains a non-default value;
if the region of pixels is a non-skipped region, composite a representation of the region of pixels into the first image frame;
and
if the region of pixels is a skipped region, avoid compositing a representation of the region of pixels into the first image frame.
