Method And Apparatus For Providing Print Quality Enhancement
view source
US Patent:

6356291, Mar 12, 2002
Filed:

Nov 6, 1998
Appl. No.:

09/187206
Inventors:

Larry Mason Ernst - Longmont CO
Assignee:

International Business Machines Corp. - Armonk NY
International Classification:

B41J 247
US Classification:

347251
Abstract:

A printing device including a first unit to receive data representing a first center pel and a set of neighboring pels. The printing device includes a second unit that compares the first center pel, the set of neighboring pels to a set of pel patterns. In one embodiment of the invention, the pel patterns only have a center pel of a first color selected from at least two separate colors. In one embodiment, the pel patterns only have a black colored pels as the center pels. In response to a match between the first center pel, the set of neighboring pels, and a pel pattern, a printing size of the first center pel is modulated. In addition, in one embodiment of the present invention, each pel pattern has a corresponding laser power level.

US Patent:

6687023, Feb 3, 2004
Filed:

Apr 17, 2000
Appl. No.:

09/550780
Inventors:

Danielle Dittrich - Longmont CO
Larry Ernst - Longmont CO
Gerhard Robert Thompson - Wappingers Falls NY
Chai Wah Wu - Poughquag NY
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

H04N 1403
US Classification:

358 313, 358 32, 358 322
Abstract:

A data processing system and method are described for generating a halftone screened image from an input image. A first threshold matrix is generated which, when utilized to halftone a solid gray input image, generates a first halftoned output image which is a plurality of generally solid vertical lines. The first threshold matrix includes a plurality of matrix elements arranged in a plurality of rows and a plurality of columns. A plurality of groups of the matrix elements are shifted within the first threshold matrix to create a second threshold matrix which, when utilized to halftone the solid gray input image, generates a second halftoned output image which is a checkerboard type pattern of alternating black or white blocks. In one embodiment, groups of the plurality of the rows are shifted horizontally over by at least one adjacent column to generate the second matrix.

US Patent:

6975427, Dec 13, 2005
Filed:

Mar 27, 2000
Appl. No.:

09/535858
Inventors:

Richard S. Lucky - Louisville CO, US
Larry M. Ernst - Longmont CO, US
Danielle Kathyrn Dittrich - Longmont CO, US
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

G06K015/00
US Classification:

358 19, 358 323, 358 316, 358463
Abstract:

Disclosed is a method, system, and program for modifying raster pel data according to different types of filtering operations. At least two tables are maintained in memory. At least two of the tables provide output pel values for at least two different types of filtering operations based on input pet values. A plurality of pets are read from raster data for a print job. A determination is made of an entry in one table based on the plurality of read pels to determine at least one output pet value that accomplishes the filtering operation associated with the table. At least two of the tables may be used in the same page of raster data to perform the different filtering operations associated with the at least two tables used within one page. The at least one output pel value is used to generate a pulse to control a printer apparatus.

US Patent:

6975428, Dec 13, 2005
Filed:

Mar 27, 2000
Appl. No.:

09/535859
Inventors:

Larry M. Ernst - Longmont CO, US
Danielle Kathyrn Dittrich - Longmont CO, US
Richard S. Lucky - Louisville CO, US
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

G06K015/00
US Classification:

358 19, 358 302, 358 312
Abstract:

Disclosed is a method, system, and program for reducing toner in an image comprised of raster pel data. A determination is made of pels surrounding subject pels. For each subject pel, a sub-pulse width power is generated to charge a sub-pel region within the subject pel based on a pattern of the surrounding pels of the subject pel. Further, for each subject pel, position information is generated indicating an alignment of the sub-pel region in the pel. The position information is used to position the sub-pel region produced by the sub-pulse width power in the pel.

US Patent:

7064859, Jun 20, 2006
Filed:

Mar 27, 2000
Appl. No.:

09/535857
Inventors:

Danielle Kathyrn Dittrich - Longmont CO, US
Larry M. Ernst - Longmont CO, US
Richard S. Lucky - Louisville CO, US
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

G06K 15/00
US Classification:

358 19, 358 304, 358 309, 358 323
Abstract:

Disclosed is a method, system, and program for generating a table for enhancing the print quality of input raster pel data. An output value is generated for different patterns of pel data. Each output value indicates a sub-pulse width power to charge a sub-pel region within a pel and position information indicating the justification of the sub-pel region within the pel. A look-up table is formed from the generated output values that enhances print quality.

Method And Apparatus For Simulating 2 Bit-Per-Pel Printing On A Bi-Level Printer Using Intelligent Double Dotting
view source
US Patent:

7345790, Mar 18, 2008
Filed:

Jan 21, 2003
Appl. No.:

10/248450
Inventors:

Danielle K. Dittrich - Boise ID, US
Larry M. Ernst - Longmont CO, US
International Classification:

H04N 1/405
US Classification:

358 307, 358 306
Abstract:

An image processing method and apparatus for enhancing the quality of a printed image without degrading overall printer performance or throughput by simulating 2 bit pel printing on a bi-level printer using intelligent double dotting. The present invention allows a bi-level printer to print an 2N dpi 1 bit-per-pel image through intelligent double dotting, thus enhancing the half resolution rendered image to approach the print quality as if the image were rendered at full resolution. In one embodiment, an enhanced resolution mode which uses a bi-level printer's 1200 dpi mode to print 600 dpi, 2 bit-per-pel images, results in an image having higher resolution quality than rendering the image using traditional halftone methods at either 600 dpi or 1200 dpi. Image enhancement through higher order resolution multiplication is also disclosed.

Method, System And Program Product For Amplitude Modulated Multiple Pel Print Quality Enhancement
view source
US Patent:

7369150, May 6, 2008
Filed:

Feb 2, 2005
Appl. No.:

11/050011
Inventors:

Larry Mason Ernst - Longmont CO, US
John Charles Wilson - Longmont CO, US
Assignee:

Infoprint Solutions Company, LLC - Boulder CO
International Classification:

B41J 2/47
US Classification:

347240, 347251
Abstract:

Disclosed is a method, system and program product for performing multiple-pel print quality enhancement (PQE) using amplitude modulation. A determination is made of an adjusted peak amplitudes value of each pel of an image. At least two adjacent pels are then grouped together and a determination is made of a peak amplitudes value that will serve as a gray amplitude value for each pel in the pel group. Also determined is position information indicating the alignment of the peak amplitudes within the combined area. The combined peak amplitudes and position information is sent as input to an amplitude modulator operating at a speed equal to the video data rate of the printer divided by the number of pels for which the peak amplitudes data is combined.

John Charles Wilson - Longmont CO, US
Assignee:

InfoPrint Solutions Company, LLC. - Boulder CO
International Classification:

H04N 1/40
US Classification:

358 302, 358 17, 358410
Abstract:

Disclosed is a method, system and program product for performing multiple-pel print quality enhancement (PQE). As in known methods of PQE, a determination is made of an adjusted sub-pulse value of each pel of an image. In accordance with embodiments of the present invention, at least two adjacent pels are then grouped together and a determination is made of a combined pulse width value to charge the combined area of the at least two adjacent pels. Also determined is position information indicating the alignment of the pulse width within the combined area. The combined pulse width and position information is sent as input to a pulse width modulator operating at a speed equal to the video data rate of the printer divided by the number of pels for which the pulse width data is combined.
