20110112805 | METHOD AND APPARATUS FOR IMPROVING VISION - Methods and apparatus are disclosed for causing the optical center of the eye to align “HIGH point” of the anterior surface of the cornea. In accordance with one aspect of the invention relating to corneal ablation procedures, the HIGH point of the eye is used as the pole of a spherical surface which is fitted approximately to a portion of the anterior surface of the cornea within a “bounded region.” For corneal ablation procedures, the “bounded region” comprises a generally inverted-cup shaped region of the anterior surface of the eye bounded at its periphery by a plane which is substantially perpendicular to a local z-axis. During the operation local high points which project above the spherical surface are ablated. According to another aspect of the invention relating to radial keratotomy procedures, a pair of incisions in the plane of a “great circle” are formed in the cornea to weaken and flatten it. As used herein, a “great circle” is formed by a plane containing the HIGH point and parallel to the local z-axis. The “bounded region” for radial keratotomy procedures is defined absolutely in terms of a circle projected onto the corneal surface which is centered about an axis passing through the HIGH point and parallel to the z-axis. | 05-12-2011 |

20080247666 | DARKNESS CONTROL USING PATTERN MATCHING - The present invention is a method and apparatus for processing image data to accomplish tuning or adjustment of images, so as to modify at least the darkness thereof, using compact, efficient methods and designs. | 10-09-2008 |
20090303556 | 4+ COLOR MANAGEMENT USING A VIRTUAL CMYK COLOR PARADIGM - A color management method, system and storage medium output 4+ color separation signals to a 4+ (5 or more) color print engine. An input source color is converted into virtual intermediate CMYK separation signals using a 4-color management tool, which may be a conventional tool. These virtual intermediate CMYK separation signals are received as input within a digital front end (DFE), which transforms the intermediate signals into 4+ separation signals, such as for a 6-color print engine. A transformation unit of the DFE passes some of the input separation signals through directly as output (without transformation) while transforming others by splitting them into light and dark separation signals, such as light and dark cyan or magenta using a blend curve that will output the same tonal quality. The transformation unit may use a blending curve that takes into account ink-limit constraints and may maximize light colorant usage to improve image smoothness in light image regions. | 12-10-2009 |
20090305154 | TRI-LEVEL XEROGRAPHY FOR HYPOCHROMATIC COLORANTS - A xerogrpahic system and method use a tri-level development process in which at least one xerographic imaging unit includes a photoreceptor and a pair of developer units. A first developer unit includes a conventional first toner of a given color (CYMK) and a second developer unit includes a hypochromatic light form of the first toner. By use of a specific tri-level process, excellent color-to-color registration can be achieved for each processed color separation because overlap between colorants can be prevented. Moreover, by use of two forms of the same colorant, a smoother tone reproduction curve can be achieved when an aggressive blending strategy is used. Gamut loss and ink limit violation can be avoided by adjusting the blending curve in certain situations. An exemplary implementation uses a four drum, eight color tandem architecture with formulations of Cyan, Magenta, Yellow and Black, as well as corresponding hypochromatic light colorants of light Cyan, light Magenta, light Yellow, and light Black (gray). | 12-10-2009 |
20100284029 | 4+ COLOR MANAGEMENT FOR GAMUT EXTENSION USING A VIRTUAL CMYK METHODOLOGY - 4+ color management sequentially processes four colors at a time from among the 4+ colors to leverage solution capability using a 4-color management tools. In methods and apparatus for processing 4+ colors, received information of 4+ colors may be processed in a first stage using four colors of the 4+ colors, such as CMYO. The processed four colors are then mapped into three virtual colors. The mapped three virtual colors and one additional unprocessed color of the 4+ colors are then processed in a second stage using a 4-color tool. From this, a second color model of at least five colors (4+) is generated, The resulting four colors determine five printer colors, and are then mapped into three virtual colors. The mapped three virtual colors and one additional unprocessed color of the 4+ colors are then processed in a third stage using a 4-color tool, From this, a third color model of at least five colors (4+) is generated. This modeling and mapping to virtual input can be repeated for once for each color beyond 4 that is supported by the printer. The processed 4+ colors are output to a device, such as a printing engine, for rendering the image. | 11-11-2010 |
20120127533 | METHOD FOR ACHIEVING HIGHER BIT DEPTH IN TAGGED IMAGE PATHS - A method adapts image data using more than eight bits per pixel to be compatible with devices using only 8-bit per pixel data. The method separates the higher bit depth data into an 8-bit image data stream, the balance of the bits are carried in a separate tag data stream. The 8-bit image data stream can be used in legacy devices that can handle only 8-bit data, and the tag data stream can be used in legacy devices that incorporate a tag data stream for their internal image processing. | 05-24-2012 |
