Abstract

Systems and methods for upscaling graphics resolution are provided. The systems and methods may selectively upscale graphics frames having a first resolution to a second resolution by various scaling methods. Depending on a variety of factors, at least a first mode of upscaling and a second mode of upscaling may provide for improved upscaling on a variety of graphics data.

First claim

What is claimed is:

1. A method for scaling graphics data, the method comprising:
selectively rendering graphics data defining rendered graphics having a first resolution and a second resolution;
upscaling the rendered graphics by a first scaling mode in response to the first resolution being a whole number multiple of the second resolution to provide processing efficiency;
upscaling the rendered graphics by a second scaling mode in response to the first resolution being a fractional multiple of the second resolution; and
displaying the upscaled graphics.

2. The method according to claim 1 , wherein the first scaling mode comprises upscaling via a pixel repeating mode.

3. The method according to claim 2 , wherein the pixel repeating mode comprises upsampling a row of existing pixels of a frame of the graphics data.

4. The method according to claim 3 , wherein the pixel repeating mode comprises upsampling a column of existing of pixels of a frame of the graphics data.

5. The method according to claim 1 , wherein the second scaling mode comprises upscaling via a polyphase scaling method.

6. The method according to claim 1 , wherein the first scaling mode and the second scaling mode are applied separately to scale a horizontal resolution component and a vertical resolution component of the rendered graphics.

7. The method according to claim 1 , wherein the first resolution is 3840×2160 pixels.

8. A system for scaling graphics data, the system comprising:
a memory unit;
a processor being configured to receive the graphics data and buffer the graphics data to the memory unit, the processor comprising at least one module configured to:
selectively rendering the graphics data to define rendered graphics having a first resolution and a second resolution;
upscale the rendered graphics by a first scaling mode in response to the first resolution being a whole number multiple of the second resolution to provide processing efficiency;
upscale the rendered graphics by a second scaling mode in response to the first resolution being a fractional multiple of the second resolution; and
display the upscaled graphics.

9. The system according to claim 8 , wherein the first scaling mode comprises upscaling via a pixel repeating mode.

10. The system according to claim 9 , wherein the pixel repeating mode comprises upsampling a row of existing pixels of a frame of the graphics data.

11. The system according to claim 10 , wherein the pixel repeating mode comprises upsampling a column of existing of pixels of the frame of the graphics data.

12. The system according to claim 8 , wherein the second scaling mode comprises upscaling via a polyphase scaling method.

13. The system according to claim 8 , wherein the first scaling mode and the second scaling mode are applied separately to scale a horizontal resolution component and a vertical resolution component of the rendered graphics.

14. The system according to claim 8 , wherein the first resolution is 3840×2160 pixels.

15. In a non-transitory computer readable storage medium having stored therein instructions executable by a programmed processor for scaling graphics data, the storage medium comprising instructions for:
selectively rendering the graphics data to define rendered graphics having a first resolution and a second resolution;
upscaling the rendered graphics by a first scaling mode in response to the first resolution being a whole number multiple of the second resolution to provide processing efficiency;
upscaling the rendered graphics by a second scaling mode in response to the first resolution being a fractional multiple of the second resolution; and
displaying the upscaled graphics.

16. The computer readable storage medium according to claim 15 , wherein the first scaling mode comprises upscaling via a pixel repeating mode.

17. The computer readable storage medium according to claim 16 , wherein the pixel repeating mode comprises upsampling a row of existing pixels of a frame of the graphics data.

18. The computer readable storage medium according to claim 17 , wherein the pixel repeating mode comprises upsampling a column of existing of pixels of the frame of the graphics data.

19. The computer readable storage medium according to claim 15 , wherein the second scaling mode comprises upscaling via a polyphase scaling method.

20. The computer readable storage medium according to claim 15 , wherein the first scaling mode and the second scaling mode are applied separately to scale a horizontal resolution component and a vertical resolution component of the rendered graphics.
