Graphics render matching for displays
View Patent ↗Technologies are presented for matching pre-processing of graphics at rendering source to post-processing at a display device to reduce undesirable effects of pre- and post-processing combinations. A rendering source may receive information associated with or otherwise determine a type of display device to which images are to be delivered. Parameters of the rendering process may then be suitably modified to take advantage of the post-processing performed by the display device or eliminate processes that may be undone by the display device. In some examples, the rendering source may communicate its pre-processing parameters to the display device and cause adjustment of post-processing parameters at the display device or, alternatively, send instructions to the display device to adjust the post-processing parameters.
1. A method to provide graphics render matching for displays, comprising:
detecting one or more post-processing parameters of a display device;
modifying a rendering process at a server based on the detected post-processing parameters such that counteracting pre-processing operations and post-processing operations are adjusted by one or more of:
eliminating one or more operations of the rendering process,
reducing a number of frames needed for image generation, and
edge defining moving objects;
transmitting one or more images generated by the modified rendering process to the display device;
transmitting an instruction to the display device to turn off one or more post-processing operations at the display device in order to prevent decreased image quality at the display device; and
enabling display of the transmitted one or more images at the display device such that an impact of post-processing at the display device resulting in the decreased image quality is substantially reduced.
2. The method according to claim 1 , wherein detecting the one or more post-processing parameters comprises one or more of:
detecting a display device type;
receiving the display device type over a network request from a client device controlling the display device; and
querying the client device controlling the display device.
3. The method according to claim 2 , wherein detecting the one or more post-processing parameters further comprises one or more of employing a look-up table and computing the one or more post-processing parameters based on the display type.
4. The method according to claim 1 , wherein the one or more images include one of a series of still images and a video stream.
5. The method according to claim 4 , wherein modifying the rendering process includes adjusting one or more of: a number of transmitted frames per second, a motion smoothing parameter, and an anti-aliasing parameter.
6. The method according to claim 1 , wherein modifying the rendering process includes determining a new render path characterization that includes one or more operations comprising: composition and animation, vertex shading, geometry shading, primitive setup, rasterization, pixel shading, and/or frame buffer blending.

transmit one or more images generated by the modified rendering process to the display device; and
enable display of the transmitted one or more images at the display device.

detecting one or more post-processing parameters of a display device;
modifying a rendering process at a game server based on the detected post-processing parameters such that counteracting pre-processing operations and post-processing operations are adjusted;
transmitting one or more images generated by the modified rendering process to the display device;
transmitting an instruction to the display device to turn off one or more post-processing operations at the display device in order to prevent decreased image quality at the display device, wherein the instruction includes a “do not post-process” flag delivered as an in-display browser, a Digital Living Network Alliance (DLNA) message, or an emulator command to invoke emulation of another screen type in a display browser or applet;
transmitting the instruction to the display device by default if a type of the display device is unknown or not detected; and
enabling display of the transmitted one or more images at the display device such that an impact of post-processing at the display device resulting in the decreased image quality is substantially reduced.
14. The computer-readable medium according to claim 13 , wherein modifying the rendering process includes one or more of: adjusting a motion smoothing parameter and an anti-aliasing parameter, and determining a new render path characterization that includes one or more operations comprising: composition and animation, vertex shading, geometry shading, primitive setup, rasterization, pixel shading, and/or frame buffer blending.
