Abstract

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.

Claims

1. A method for providing 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;

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 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.

7-12. -12. (canceled)

13. A server adapted to match graphics rendering for displays, comprising:

a memory adapted to store instructions;

a communication module; and

a processing unit for communication with game client devices via one or more networks in conjunction with the stored instructions, wherein the processing unit is configured to;

detect one or more post-processing parameters of a display device;

modify a rendering process based on the detected post-processing parameters to eliminate one or more rendering process operations that will be reversed by post-processing at the display device;

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.

19. The server according to claim 13, wherein the processing unit is further configured to create an impact register that includes a post-processing type and a severity level for each render path operation.

20. The server according to claim 13, wherein the processing unit is further configured to employ a combination of one or more of the render path operations to reduce the impact of post-processing.

22. The server according to claim 13, wherein the processing unit is further configured to:

monitor the post-processing parameters throughout a transmission of a game; and

update the rendering process in response to a change in the post-processing parameters.

23. The server according to claim 22, wherein the change in the post-processing parameters includes a change of a display device type.

24. The server according to claim 13, wherein the display device is one of a television set, a projector, a mobile device display, a wearable display, and a headset display.

25. A computer-readable medium with instructions stored thereon for providing graphics render matching to display post-processing, the instructions comprising:

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;

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.
