7352373 Systems and methods for multi-dimensional dither structure creation and application  
Embodiments of the present invention comprise systems and methods for creation, modification and implementation of dither pattern structures.
7295701 Methods and systems for efficiently processing image data for reproduction  
The methods and systems according to the current invention allow the use of slower and inexpensive image-processing components by approximating or compressing color image data prior to image...
7268783 Image alias rejection using shaped statistical filtering  
Image alias rejection when converting a high resolution rasterized waveform to a lower resolution rasterized waveform for display uses a statistical filter. The statistical filter provides a shaped...
7054037 Method and apparatus for dithering or undithering data words in a data stream  
Method and apparatus for dithering and undithering data words in a data stream. The method comprises the steps of processing a data word in a data stream to obtain an output data word by...
6441867 Bit-depth extension of digital displays using noise  
A method for extending bit-depth of display systems. The method includes the steps of measuring the static display noise of a display device, using the display noise to create pseudo-random noise...
5737455 Antialiasing with grey masking techniques  
A method of combining antialiased edges for printing or display at a grey level reproduction device, wherein pixels have shade values determined as a function of their neighbor's shade values and...
5619230 System and method for real-time image display palette mapping  
A system and method for digital video imaging is provided. Complimentary dither patterns are applied to green and magenta components of the image. The complement nulls out the dither pattern from...
5598184 Method and apparatus for improved color recovery in a computer graphics system  
Color information lost in a computer graphics system as a result of encoding by dithering is recovered by passing the encoded data through a filter that has the same effective shape and size as the...
5526021 Dithering optimization techniques  
A process of producing large dither matrices suitable in use in halftoning images is disclosed. This process includes forming an objective function based on the placement of the dither values...
5455600 Method and apparatus for mapping colors in an image through dithering and diffusion  
A high color resolution image is accurately approximated with a low resolution image through a unique combination of ordered dithering and error diffusion. The true color of each pixel is modified...
5260810 Image processing apparatus with improved dithering scheme  
This invention utilizes the fact that "a maximum density difference in a window within a predetermined range including a pixel of interest is large for a character region, and is small for a...
