Patent number: 7345797Abstract: Stopping and starting the movement of media in a scanner before completion of scanning can generate artifacts in the display of the scanned image. These artifacts arise from measurements made during the deceleration of the media before stopping and the acceleration of the media after starting. By scanning the regions that pass the optical sensor during deceleration and acceleration of the media while the media is moving relative to the optical sensor at a substantially constant speed, the degree to which artifacts are produced is reduced. The scanning of the sections of the media corresponding to the deceleration and acceleration distances of the media can be done by moving the optical sensor while the media is stationary, or, by moving the media while the optical sensor is stationary.Type: GrantFiled: October 24, 2003Date of Patent: March 18, 2008Assignee: Hewlett-Packard Development Company, L.P.Inventor: Arlin R.

Patent number: 6678426Abstract: Lower resolution source data is synthesized to a higher resolution format for subsequent rendering on a lower resolution output device. Synthesis occurs by selecting or generating and using a synthesis template that represents a configuration of a plurality of pixel data in the higher resolution format into which the lower resolution source data is to be synthesized. A working or active pixel is identified from the lower resolution source data, a synthesis template is selected, and then the synthesis template pixel data is substituted for the working pixel for rendering on the output device. The synthesized higher resolution data is rendered in a manner such that dots represented by the synthesized data are formed interstitially relative to scan lines of the given lower raster/resolution capability of the output device. The working pixel is identified in the lower resolution data by recognizing a configuration of a plurality of pixel data adjacent the working pixel.Type: GrantFiled: March 24, 1998Date of Patent: January 13, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: James G.

Patent number: 6359642Abstract: The present disclosure describes techniques that can be used to reduce the time required for a printer or printing system to generate printed output. Printers are provided that operate to move from an idle mode into a print mode upon receiving a PRE-START signal. Printers are also provided that operate to remain in a print mode for an extended period of time upon receiving a PRE-START signal. The PRE-START signal is a signal that indicates one or more “pre-print”acts have been performed. In addition, printing systems are provided that include peripheral devices adapted to transmit a PRE-START signal to a printer upon the detection of one or more PRE-PRINT acts.Type: GrantFiled: January 27, 1999Date of Patent: March 19, 2002Assignee: Hewlett-Packard CompanyInventors: Kenneth K. Smith, Arlin R. Jones

Patent number: 5987221Abstract: Text and line art image data is distinguished from halftone image data for selectively enhanced rendering thereof. Specifically, a method of rendering a raster pixel image from a stored bitmap includes (i) determining whether an orphan pixel is detected within a bounded sampling window of the bitmap, and, (ii) processing at least one selected pixel of the bitmap within the sampling window relative to the determining of whether an orphan pixel is detected. In general, an orphan pixel is defined as an isolated white or black pixel in a halftone image. In one embodiment, an orphan pixel is recognized as having a predefined pixel value and as having no other pixels with that value adjacent thereto within the sampling window. In the event an orphan pixel is detected within the window, then the bitmap within the window is determined to be halftone image data and the selected pixel is processed accordingly.Type: GrantFiled: January 24, 1997Date of Patent: November 16, 1999Assignee: Hewlett-Packard CompanyInventors: James G Bearss, Eugene A Roylance, Terry M.

Patent number: 5684981Abstract: A method and device for multidimensional data transformation is disclosed. A multidimensional, non-linear data memory storage construct provides simultaneous access to data in all dimensions without duplication of memory. For "n" dimensions, 2.sup.n locations describe the smallest subarea location in the multidimensional construct. Therefore, 2.sup.n memory banks are provided in which to store corresponding interpolation data. By recognizing that boundary points of the n-dimensions are common, duplication of memory is avoided by providing an addressing and sorting mechanism which allows interpolation of stored data correlated to the input data.Type: GrantFiled: January 18, 1995Date of Patent: November 4, 1997Assignee: Hewlett-Packard CompanyInventor: Arlin R.

Patent number: 5337160Abstract: A data processing system converts a raster image of grey scale value pixels into an image of binary value pixels and diffuses pixel value errors that result from the conversion. The data processing system initially converts a grey scale value pixel to a binary value pixel, determines an error value for the pixel by finding a difference between the pixel's binary value and its previous grey scale value; derives error diffusion values attributable to immediately adjacent pixels in a next line of the raster image and stores those attributable error diffusion values. Upon reaching one of the immediately adjacent grey scale value pixels in the next line, and during a conversion of that pixel from its grey scale value to a binary value, the attributable stored error diffusion values are accessed and combined with the adjacent pixel's grey scale value.Type: GrantFiled: July 1, 1992Date of Patent: August 9, 1994Assignee: Hewlett-PackardInventor: Arlin R.
