Methods and apparatus to render colors to binary high-dimensional output device

Abstract

Disclosed are methods and apparatus for color rendering in a binary high-dimensional output device, for example. The methods and apparatus are configured to receive color space data, and then map the received data to an intermediate color space. From this intermediated space, color rendering is performed using a pre-generated number of extended primary colors for temporal modulation. Each of the pre-generated extended primary colors is made up of a combination of at least two subframes with each subframe having a respective primary color. Through use of temporally modulated, pre-generated extended primaries in the color space, the methods and apparatus afford a reduction in the diffusion error for subsequent neighboring pixels yet to be rendered, particularly when using constrained devices such as binary high-dimensional output devices.

Background technique [0004] For a display device, in order to produce the intended color that will be displayed on the target display device, the source color (for example, the source color space represented as a tuple of numbers in standard RGB (sRGB)) must usually be transformed into the target device's Color space (e.g. RGB fo...

[0006] However, even with downsized LUTs, in some display devices (such binary high-dimensional output devices), conventional interpolation methods do not work

For example, given a standard sRGB color space input, for a limited high-dimensional binary output device (i.e., limited to three output colors), problems arise during interpolation into the device color space, where conventional interpolation would make this A device that simultaneously has more than three different pixel color settings in the pixel array that modulates the color is not valid when restricted to using three colors to render a particular interpolated color
