| 7301673 | Error diffusion processing method An error diffusion processing method includes determining a binary value of an input pixel according to a grayscale level of the input pixel, searching a nearest pixel that has the same binary value as the input pixel, and comparing a measured actual distance with a... | 11/27/2007 |
| 7239429 | Method and apparatus for generating dispersed cluster screen A method for generating a dispersed cluster screen defining a stable environment for printing an image is provided. The method initiates with generating a pattern of cluster centroids. Then a cluster growth sequence is defined. Next, a cluster is grown around the cl... | 07/03/2007 |
| 7233339 | Method and apparatus for performing dithering A method and apparatus for dithering may provide filtering M bit data and performing a temporal/spatial compensation based on LSB of the filtered M bit data. The dithering may be performed on a selected frame. M-2 bits of the M bit data may be specified as a referen... | 06/19/2007 |
| 7190380 | Generating and displaying spatially offset sub-frames A method of displaying an image with a display device includes receiving a first set of image data for a first image. A first sub-frame and a second sub-frame corresponding to the first set of image data are generated. A bit-depth of the first and the second sub-fra... | 03/13/2007 |
| 7102791 | Mask producing method, image outputting device and computer readable recording medium A mask is produced for converting multi-level image data into a halftone image through comparison with a threshold for each pixel. For this purpose, a dot pattern is determined on each of predetermined gray scale levels, and, the mask is created by the dot patterns ... | 09/05/2006 |
| 7061650 | Method and apparatus for bayer mosaic image conversion A method of, and an apparatus for, image conversion. The three color channels of a Bayer mosaic image are up-interpolated from input space to output space. The pixels sampled from each two-dimensional color plane of the Bayer image are convolved with a coefficient k... | 06/13/2006 |
| 6982799 | Creating composite page images from compressed data A printhead controller controls printing of a page by at least one printhead. The printhead controller, in use, receives data, in a compressed format relating to the page to be printed, the data including a page description comprising a bi-level black layer and a co... | 01/03/2006 |
| 6724499 | Pseudo halftone image expression method There is provided a pseudo-halftone image expression method capable of processing vector data with an excellent image quality and small computational complexity. Gray levels of n×n/m are expressed by varying the number of formed dots within a matrix of n×n dots on... | 04/20/2004 |
| 6680786 | Image processing method and device for half-tone representation A method of representing a half-tone level with dot sets each comprised of contiguous dots including the steps of providing a dot-set center at an offset point that is neither a center of a dot nor a midpoint between centers of dots, selecting dots that a... | 01/20/2004 |
| 5832122 | Method of processing image data When threshold data of a threshold matrix are to be established, they are determined in an ascending or descending order so as to maximize the distance between the thresholds in the threshold matrix and other identical threshold matrixes positioned in sur... | 11/03/1998 |
| 5696602 | Method for halftoning using stochastic dithering with minimum density variance A dispersed-dot stochastic dither array is provided for rendering halftone images having excellent visual quality and are created by a minimum density variance method.
