    Abstract: Method and apparatus for generating a halftone image for a multi-level output device employing a dither matrix generated by minimizing a visual cost function. The dither matrix is addressed by the least significant bits of a pixel address and the value supplied by the dither matrix is added to the pixel value. The resulting sum is quantized in a quantizer to produce the multi-level halftone value.

    Abstract: A method of calibrating a four color printer capable of printing three colors and black, includes the steps of: forming a minimum black data structure representing a minimum black strategy; forming a maximum black data structure representing a maximum black strategy; for each printable black level, forming a fixed black data structure; and for a specific output color value, finding the minimum and maximum black levels using the minimum and maximum black data structures, determining a desired black level between the minimum and maximum black levels according to a defined black strategy, and determining the three printing color levels from the fixed black data structure corresponding to the desired black level.

    Abstract: This invention provides a method for mapping an input color space to an output color space in such a way that the color reproduction characteristics of the saturated colors can be adjusted in a custom manner, while maintaining the desired tone reproduction on the neutral axis. This is accomplished by defining independently a tone transformation and a transformation for a plurality of highly saturated colors. A transformation is formed for the remaining color values having the specified transforms for the neutral and saturated colors as boundary values. In the preferred embodiment multi-dimensional look-up tables are used to implement the transform.

    Abstract: This invention minimizes the color errors associated with performing conversion and/or correction of color digital image data using multi-dimensional look-up tables of a limited size. By distributing the errors across the color gamut it is possible to reduce the average color error as well as the maximum color errors associated with linear or conventional linear or nonlinear, e.g. cube-root or logarithmic, remapping schemes. The resulting advantage will be color images with greatly reduced artifacts.
