  • Publication number: 20100073568
    Abstract: The optical performance is enhanced of display systems that use field sequential color and pulse width modulation to generate color and color gray scale values. Such enhancement may be achieved by various data encoding methods disclosed herein that may include temporal redistribution of bit values to mitigate color motional artifacts associated with field sequential color-based display systems, selective combination of intensity modulation, pulse width modulation, and/or the noncontiguous sequencing of primary colors. There is further an intelligent real-time dynamic manipulation of gray scale values in portions of an image that are computationally determined to be images of objects moving against a global background, so as to temporally front load or concentrate the bits comprising such moving objects and thereby further mitigate said motional artifacts using both actual and virtual aggregate pulse truncation across all primary colors being modulated.

  • Publication number: 20100007791
    Abstract: A system is disclosed that enhances television viewing by providing users the ability to selectively blank a portion of their screen. Broadcasters today often dedicate some percentage of display “real estate” to push additional content (e.g., scores from other games, regional weather forecasts, etc.) via a virtual “ticker tape”. More often than not, the average viewer will find the ticker tape a distraction if not an annoyance after a short period of time. The embodiments discussed herein allow the viewer a means by which to blank that portion of the screen. The user moves a cursor to designate a portion of the screen to be blanked.

  • Patent number: 7583733
    Abstract: The invention provides systems and methods for providing compressed video data from multiple bit streams. The systems and methods apply a two-stage strategy. In the first stage, a conditioning step is performed on a bit stream comprising compressed video data which outputs a conditioned bit stream that is able to receive digital insertions without subsequent decompression of the compressed video data or removal from network packets. The conditioning includes recoding an incoming bit stream such that compressed video data in the bit stream immediately before and after a splice point does not have temporal reliance across the splice point. In the second stage, e.g., at a downstream network device, splicing of compressed video data from a second bit stream into the conditioned bit stream is performed. The splicing takes advantage of the changes made to the conditioned bit stream and may occur at the network packet level.

    Abstract: A key signal control unit for controlling the level of a key signal corresponding to an arbitrary position within a frame area to a level corresponding to a minimum distance from an inner edge of the frame area on the basis of the level of a key signal on the inner edge of the frame area as a reference value so that the frame area appears along an outer circumference of an image corresponding to a video signal. A totally new image special effect is thus made on the video signal.

  • Patent number: 7245783
    Abstract: A method for synthesizing noise in a digital image comprises the steps of (a) estimating noise statistics based on a set of spatial autocorrelation coefficients and a set of spectral correlation coefficients that correspond to the color channels of the image, where at least one of the spatial autocorrelation coefficients is weighted by at least one of the spectral correlation coefficients, thereby providing a weighted set of autocorrelation coefficients, and where a set of filter coefficients is obtained from the weighted set of autocorrelation coefficients; and (b) synthesizing a synthetic texture by using the filter coefficients to filter a random noise field in each of the color channels, thereby producing output noise fields in each of the color channels that replicate a synthetic texture, e.g., a desired grain appearance, when combined into the digital image.

  • Patent number: 7199836
    Abstract: As information to be processed at an object-based video or audio-visual (AV) terminal, an object-oriented bitstream includes objects, composition information, and scene demarcation information. Such bitstream structure allows on-line editing, e.g. cut and paste, insertion/deletion, grouping, and special effects. In the interest of ease of editing, AV objects and their composition information are transmitted or accessed on separate logical channels (LCs). Objects which have a lifetime in the decoder beyond their initial presentation time are cached for reuse until a selected expiration time. The system includes a de-multiplexer (1), a controller (2) which controls the operation of the AV terminal, input buffers (3), AV objects decoders (4), buffers (4?) for decoded data, a composer (5), a display (6), and an object cache (7).

  • Patent number: 7154540
    Abstract: Pan, tilt and zoom sensors are coupled to a broadcast camera in order to determine the field of view of the broadcast camera and to make a rough estimate of a target's location in the broadcast camera's field of view. Pattern recognition techniques can be used to determine the exact location of the target in the broadcast camera's field of view. If a preselected target is at least partially within the field of view of the broadcast camera, all or part of the target's image is enhanced. The enhancements include replacing the target image with a second image, overlaying the target image or highlighting the target image. Examples of a target include a billboard, a portion of a playing field or another location at a live event. The enhancements made to the target's image can be seen by the television viewer but are not visible to persons at the live event.

  • Patent number: 7145606
    Abstract: A method for post-synchronizing information stream includes obtaining lip-objects from a video signal. The original lip-objects are replaced with new lip-objects which correspond to a translated audio signal. The new lip-objects may be obtained by tracking a further video signal or by using a database with visemes or lip-parameters. For a multi-language information stream, a desired language may be selected at the receiver.

  • Patent number: 7091993
    Abstract: A system and method are disclosed for digitally compositing an object from an input image onto a destination image. The object is composited from an image having an arbitrary or non-uniform colored background containing some non-static elements onto a destination image with reduced effects from shadows cast by the object and with reduced gaps or holes within the object. Various improvements in the compositing procedure such as shadow reduction and hole filling, and less restrictive requirements regarding the object's surroundings are disclosed. A background model is created and a frame of an input image containing the object is obtained. An alpha image is created in which each pixel is either a zero, indicating it is not part of the object, or a one, indicating that it is part of the object.

  • Patent number: 7030902
    Abstract: The method uses three pictures, A, B and C, two of which are substantially similar pictures having images, A, B, and one that is dissimilar, usually a solid color, C. Continuous movement is created by repetitively viewing the series A, B, C. Additionally, each picture can be blended or superimposed to create a blended A/B, C/A and B/C and then the blend put together with the others, in a series, C/A, A, A/B, B, B/C, C. This series is then repeated a plurality of times to create an illusion of sustained, ongoing motion with a degree of three-dimensionality, with synchronous Pulfrich light-filtering available to enhance the effect.
