  • Patent number: 7573596
    Abstract: In an exemplary method, a driver for a printing device receives a print job that comprises a document. The driver generates multiple samples that simulate the appearance of at least a portion of the document with different values for at least one print setting. The driver provides a visual presentation of the multiple samples on an output medium of an output device. The output device may be a display device, a printing device, etc. The driver juxtaposes the multiple samples on the output medium. When a user selects one of the multiple samples, the driver receives notification of the sample that was selected. In response, the driver configures the at least one print setting in accordance with the selected sample.

  • Patent number: 7572566
    Abstract: According to the method of producing toner, toner is produced by (i) forming particles of a pigmented resin by applying shear stress to a mixture of a pigmented resin composition, an organic solvent, a polymer dispersing agent, and a hydrophobic medium, the organic solvent being capable of reducing viscosity of the pigmented resin composition, and said polymer dispersing agent having a glass transition point in a range of 50° C. to 80° C. and an SP value in a range of 8.5 to 10, (ii) distilling off the organic solvent, and (iii) separating the toner from the hydrophobic medium and drying the toner. With the above arrangement, the method makes it possible to (i) easily downsize toner particle without causing thermal decomposition of a resin or separation of a release agent, and (ii) produce toner that is small in particle size, excellent in humidity-resistance, and less likely to aggregate.

  • Publication number: 20090195488
    Abstract: A segmented-pixel liquid crystal display has a plurality of pixels of which each has three sub-pixels 10a-10c, namely one middle and two side sub-pixels, arranged next to one another in the column or row direction. The sub-pixels 10a-10c have different brightness levels when the pixel as a whole is in a given middle halftone state, and the middle sub-pixel 10a has the highest brightness level. This eliminates unnaturalness as is conventionally produced when an image with a straight border is displayed, and further improves the gamma characteristic.

  • Patent number: 7570834
    Abstract: An image de-ringing filter system and method are provided. The method comprises: accepting image pixels; collecting data from a first group of pixels neighboring a test pixel; in response to the first group data, deciding if the test pixel includes image ringing artifacts; collecting data from a second group of pixels neighboring the test pixel; in response to the second group data, generating a filtered value (FV); and, replacing the test pixel actual value with FV. Typically, collecting data from the first and second group of pixels includes the performance of a mathematical operation. For example, a matrix may be defined for the multiplication of the first group of pixels. Values of pixels on a first side of the coordinate axis may be subtracted from pixels on a second side of the coordinate axis, opposite of the first side. Then, the difference is compared to a threshold.
