Abstract

Image pixel to temporal pixel mapping is disclosed. In some embodiments, a grid of stochastically arranged temporal pixels is employed in a composite display. An image pixel may be mapped to one or more temporal pixels in the grid. One or more of the one or more temporal pixels in the grid to which the image pixel is mapped are employed to render the image pixel in the composite display.

Claims

1. A method for image to temporal pixel mapping, comprising:

obtaining a grid of stochastically arranged temporal pixels, wherein each temporal pixel corresponds to a pixel element at a given sweep location; and

mapping an image pixel to one or more temporal pixels in the grid;

wherein one or more of the one or more temporal pixels in the grid to which the image pixel is mapped are employed to render the image pixel.

2. A method as recited in claim 1, wherein the pixel element is installed on a paddle.

3. A method as recited in claim 2, wherein the paddle is configured to sweep out an area.

4. A method as recited in claim 1, wherein the sweep location of the pixel element varies with time.

5. A method as recited in claim 1, wherein the sweep location of the pixel element varies with angle.

6. A method as recited in claim 1, wherein the image pixel is included in an image being rendered by temporal pixels in a composite display.

7. A method as recited in claim 1, wherein temporal pixel positions in the grid are stochastically determined.

8. A method as recited in claim 1, wherein temporal pixel positions in the grid are not aligned.

9. A method as recited in claim 1, wherein the grid comprises a first grid and wherein obtaining the first grid of stochastically arranged temporal pixels comprises randomly selecting a subset of temporal pixels included in a second grid.

10. A method as recited in claim 9, wherein the second grid is of a higher resolution than the first grid.

11. A method as recited in claim 1, wherein obtaining a grid of stochastically arranged temporal pixels comprises selecting one or more of a number of pixel elements installed on a paddle, a placement of the pixel elements on the paddle, and a rotation rate of the paddle.

12. A method as recited in claim 1, wherein a density of temporal pixels in the grid varies across the grid.

13. A method as recited in claim 1, wherein at least a portion of an image comprising the image pixel rendered by the grid of stochastically arranged temporal pixels is invariant to slight angular rotations.

14. A method as recited in claim 1, wherein the grid of stochastically arranged temporal pixels is associated with a display area of a first paddle of a composite display and further comprising selecting a different grid of stochastically arranged temporal pixels for a display area of a second paddle of the composite display.

15. A system for image to temporal pixel mapping, comprising:

a processor configured to;

obtain a grid of stochastically arranged temporal pixels, wherein each temporal pixel corresponds to a particular pixel element at a given sweep location; and

map an image pixel to one or more temporal pixels in the grid, wherein one or more of the one or more temporal pixels in the grid to which the image pixel is mapped are employed to render the image pixel; and

a memory coupled to the processor and configured to provide instructions to the processor.

16. A system as recited in claim 15, wherein temporal pixel positions in the grid are stochastically determined.

17. A system as recited in claim 15, wherein temporal pixel positions in the grid are not aligned.

18. A computer program product for image to temporal pixel mapping, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

obtaining a grid of stochastically arranged temporal pixels, wherein each temporal pixel corresponds to a particular pixel element at a given sweep location; and

mapping an image pixel to one or more temporal pixels in the grid;

wherein one or more of the one or more temporal pixels in the grid to which the image pixel is mapped are employed to render the image pixel.

19. A computer program product as recited in claim 18, wherein temporal pixel positions in the grid are stochastically determined.

20. A computer program product as recited in claim 18, wherein temporal pixel positions in the grid are not aligned.
