In one embodiment, the surround visual field is displayed in an area partially surrounding or surrounding the video content being displayed. This surround visual field may be comprised of a plurality of elements that further enhance the effect of the content being displayed. For example, one embodiment of the invention provides for elements within the surround visual field to move in relation to motion within the video content being displayed. Other characteristics of the video content may also be supplemented by the surround visual field or the surround visual field may be authored, at least in part, to correspond to the content itself. In embodiments, the surround visual field may be a rendering of a three-dimensional environment. In embodiments, one or more otherwise idle display areas may be used to display a surround visual field.

Abstract: Methods and systems are disclosed for processing image frames to reduce the bandwidth requirements. Embodiment of the present invention may include mode-specific image frame rendering in photorealistic and non-photorealistic modes, such as outline and cartoon modes. In embodiments, update regions may be identified and reduced by an edge position mask. In embodiments, update regions may be bounded by rectangles and such regions may be reduced in number by merging regions together using various no-cost or cost approaches. To improve compressibility, regions to be transmitted that do not require updating at the receiver may be encoded as transparent.

Abstract: An adaptive halftone scheme is applied to a compound document to smooth the rendering while preserving edge sharpness. The adaptive halftone scheme involves identifying document regions as either smooth, edge or texture. Each identified region is then processed as follows. Wherever a smooth region is adjacent to an edge region and wherever a smooth region is adjacent to a texture region, create a transition region in a portion of that smooth region bordering that other region and apply a blend of a screening halftone technique (SCN) and an error diffusion with screening halftone technique (EDSCN) to that transition region, apply SCN to the remainder of that smooth region, apply ED to that other region if it is an edge region, and apply either EDSCN or SCN if it is texture region.

Abstract: We improve text reproduction of a scanned and printed image by identifying text-contribution colors and also image-contribution colors that are in or near the text region of the color space. When input colors are encountered that contribute both to text and image we splice together text and image color transformations of the input color to produce a color in the printer color space. We improve background reproduction, i.e. reduce bleed-through artifacts, by identifying background-contribution colors and also image-contribution colors that are in or near the background region of the color space. When input colors are encountered that contribute both to background and image we splice together background and image color transformations of the input color to produce a color in the printer color space.

Abstract: An image processor (14) in a photocopier (10) takes composite input image (20a) that includes a plurality of skewed sub-images (22a, 24a, and 26a). It revises the image so as to produce an output composite image (20b) containing aligned sub-images (22b, 24b, and 26b). To identify the input image's sub-images, the image processor (14) identifies connected groups (44, 48 and 54) of pixels that meet certain criteria, and it eliminates from consideration each group (48) whose bounding box (50) is included within the bounding box (46) of another connected group (44). Skew angles for the different sub-images are determined by finding the best-fit lines through the outline pixels of their respective connected groups, and the sub-images are de-skewed by the negatives of those lines' angles.

Abstract: The appearance of edges in an image is improved through precise placement of subpixels within pixel cells that are located on or near edges in an image. Image data is examined to identify a “target pixel” near the edge of an object that represents the object and is adjacent to a “background pixel” that represents only background. The target pixel may represent both the object and its background or it may represent the object only. A “second pixel”, adjacent to the target pixel and representing the object, is also identified. The second pixel may represent both the object and its background or it may represent the object only. The target pixel's location with respect to the second pixel is analyzed to determine the placement of a subpixel within the target pixel cell and the placement of a subpixel within the second pixel cell, such that the edge of the object is well-defined and the density of the object is preserved. A vertical smoothing process can additionally be performed to improve further the appearance of edges in the image. The technique is particularly advantageous for printing a halftoned object represented by pixels that are not saturated.

Abstract: Techniques for securely displaying text on a display panel involve destroying spatial and temporal correlations in an otherwise uniform visual field. The techniques render the displayed text secure with respect to attempts to copy the text using a video capture device or still-picture camera. The techniques also render the displayed text unreadable to casual over-the-shoulder viewing by strangers outside of a certain narrow reading area.

Abstract: A fast technique utilizes overcomplete DCT representations and performs de-blocking, de-noising and de-blurring by thresholding and transforming the transform coefficients to process images obtained from inexpensive sensors/cameras with low-quality compressed image output. A color balance algorithm is used to compensate for hue shifts. Quality differences between color channels and inter-channel correlations are exploited to significantly reduce computational requirements and yield a high-performance technique for processing such images before printing.

Abstract: An apparatus and method for improving a color space transformation between an input device such as a scanner and an output device such as a printer. The color space transformation includes a first three-dimensional look up table that receives color information from the input device and transforms colors specified in an input device color space into colors in a device-independent color space, and a second three-dimensional look up table that receives colors from the first three-dimensional look up table and transforms colors specified in a device-independent color space into colors in an output device color space. The method includes inputting sample images with the input device and outputting those sample images with the output device, identifying areas in the sample images output by the output device where contouring appears, forming a list of colors corresponding to the identified areas, identifying nodes in the second three-dimensional look up table encompassing the list of colors, and smoothing the set of nodes.
