  • Publication number: 20200134780
    Abstract: Peripheral-vision expanded images are streamed to a video streaming client. The peripheral-vision expanded images are generated from source images in reference to view directions of the viewer at respective time points. View direction data is collected and received in real time while the viewer is viewing display images derived from the peripheral-vision expanded images. A second peripheral-vision expanded image is generated from a second source image in reference to a second view direction of the viewer at a second time point. The second peripheral-vision expanded image has a focal-vision image portion covering the second view direction of the viewer and a peripheral-vision image portion outside the focal-vision image portion. The second peripheral-vision expanded image is transmitted to the video streaming client.

  • Patent number: 9602835
    Abstract: Techniques described herein convert a plurality of digital images into an image or images more amenable to data compression. In one embodiment, an ordered collection of input digital images is provided. A first digital image from the ordered collection is identified as a base image, and an empty image strip is formed. For each second digital image from the ordered collection, and upon a condition in which the second image is the base image, the base image is appended to the image strip. Upon a condition in which the second image is not the base image, a difference image is computed from the base image and the second image and appended to the difference image to the image strip. Quantization and conventional image compression may be applied to the image strip to produce a compressed image strip.

  • Patent number: 8520938
    Abstract: A method for adjusting a color in a color space comprises adjusting the color along a gradient path to a point in or on a color gamut. The gradient path is determined from a potential field derived from the color gamut consisting of gamut points in the color space. The potential field can be derived from one or more points in the color gamut and different functions may be used to determine the potentials due to different points in the gamut. The potential at a point in the color space due to the gamut point can be a function, including an inverse power, of distance of the point in the color space from the gamut point. The gradient path can be determined from the gradient of the potential field by quadric error-based surface simplification of a surface mesh representing a surface of the gamut.

  • Patent number: 8399177
    Abstract: An improved relief printing plate and method for producing said plate is disclosed. Substantially all sizes of relief features resolve a fixed pattern which improves print quality. The pattern is applied to image areas in halftone data used to produce an image mask that is subsequently used to convert a plate precursor into a relief plate. The accuracy, ink density and tonal response of printed images corresponding to relief features that include the pattern are comparable or better than relief features produced without the pattern.

  • Patent number: 7900144
    Abstract: Modification of color values in a page description file can be carried out by converting implicit color commands within the page description file to explicit color commands. The color values specified by the explicit color commands within the page description file then are adjusted to calibrate an output device for enhanced color fidelity. Implicit color commands specify color values indirectly, for example, by defining color as a function of other graphic information and color reference values. Consequently, color modification prior to RIP conversion generally is difficult. Conversion and modification of explicit color values provides a higher degree of color conversion accuracy without the need for RIP conversion of the page description file.

  • Patent number: 7495804
    Abstract: A color imaging technique includes setting a target value in a device-independent first color space and mapping the target value to a substantially complete point set in a second color space. The point set may include a plurality of points, each of which define substantially the same calorimetric value via a unique combination of colorants. After mapping the target value to a substantially complete point set, a point may be chosen. Moreover, after choosing a point in the point set, device-dependent colorant values defined by the point may be determined. In this manner, the invention may provide control over the colorants that are used to image a particular color.

  • Patent number: 7382379
    Abstract: A color mapping method is used in transforming colors between color imaging systems. The method includes using forward transformation profiles that characterize the color imaging systems to generate respective sets of device-independent color values for the color imaging systems. Color conversions are calculated by recursively reducing differences between the respective sets of device-independent color values. Based on these color conversions, a color map is constructed that describes a relationship between the color imaging systems.

  • Patent number: 7292368
    Abstract: Techniques are described for preparing halftone bitmap images for printing on inkjet printers. The techniques may involve exclusive use of low-density inks to reproduce highlight colors and means for reducing the amount of ink applied to the page within “solid” areas while maintaining complete coverage of these areas. The techniques may rely on the high addressability and larger ink palette of recent inkjet printers. For example, some inkjet printers offer seven ink channels: low and high density inks for the cyan, magenta, and black channels, and a single high-density yellow ink. In one embodiment, halftone dots within a bitmap image are separated into perimeter data and core data. The perimeter data is then associated with a low-density ink channel and the core data is associated with a high-density ink channel.
