  • Patent number: 11039153
    Abstract: A video keying processing device is provided which comprises memory configured to store data and a processor configured to determine, which pixel portions, in a YUV color space of a first video comprising a foreground object and a background color, represent the foreground object and the background color of the first video. The processor is also configured to, for each pixel portion of the first video determined to represent the foreground object and the background color, convert YUV values of the pixel portion to red-green-blue (RGB) color component value and determine a blended display value for each RGB color component of the pixel portion based on a blending factor. The processor is also configured to generate a composite video for display using the blended display values of each pixel portion determined to represent the foreground object and the background color.

  • Patent number: 8477149
    Abstract: A method, system and computer readable media for real-time chromakey matting using image statistics. To identify the chroma key spectrum, the system/method executes in three stages. In an off-line training stage, the system performs semi-automatic calibration of the chroma key parameterization. In the real-time classification stage, the system estimates the alpha matte on a GPU. Finally, an optional error minimization stage improves the estimated matte, accounting for misclassifications and signal noise. Given the resulting matte, standard alpha blending composites the virtual scene with the video feed to create the illusion that both worlds coexist.

    Abstract: The claimed subject matter relates to a computer-implemented architecture that can generate a map. The map can be a hybrid between an orthographic projection map and street-side images, thus including useful aspects from both types of representations. For example, an orthographic projection map is very effective at presenting global relationships among the features of the map but not effective at presenting local detail. In contrast, street -side images show excellent detail but do not convey the global information of an orthographic projection map. The hybrid map can thus provide a richer set of information than conventional maps and can also display objects/features of the hybrid map in multiple perspectives simultaneously on a single representation that is printable.

    Abstract: An interactive video compositing device includes a chroma-key mixer, video switcher and control circuitry. The chroma-key mixer generates a composite image by combining a real-time image, such as one captured by a video recorder, with a prerecorded video image, such as a movie. The composite image includes the modified real-time image superimposed, or overlaid, onto the prerecorded image. The video switcher automatically selects either the composite image or the prerecorded image to be output to a display. The control circuitry controls the video switcher and other outputted signals based on data file information that corresponds to content of the prerecorded image or media. For example, the data files may contain information relating to the presence (or absence) of a particular character in a movie scene, thus allowing for the output and display, at appropriate times, of the real-time composite image instead of the prerecorded image.

  • Patent number: 7221724
    Abstract: A precision timing generator and an associate method provide a precise clock signal based on a reference clock signal. Using the reference clock signal in a phase locked loop or delay locked loop, a number of clock signals of equal frequency are generated separated consecutively by a known phase. Two of these clock signals of consecutive phases are selected for interpolation for higher precision according to predetermined weights. The resulting interpolated clock signal has a phase offset that is intermediate between the selected clock signals in proportion to the predetermined weights. In one implementation, a second interpolated clock signal is created by selecting and weighting a second group of clock signals using independent selection and weights. The two interpolated clock signals are then combined by logic operations to provide a precise clock signal of predetermined duty cycle and phase.

  • Patent number: 7213255
    Abstract: Disclosed is a system for generating a graphics window that is capable of emulating enhanced video from a combined video and interactive content stream. The set-top emulator can randomly access the combined video and interactive content stream to provide an easy manner of randomly accessing portions of the combined video and interactive stream for quality control purposes. Random access allows selective viewing of the enhanced video which saves time. Additionally, the combined video and interactive content stream can be simultaneously viewed as it is being produced to allow immediate feedback to an interactive television producer.

  • Patent number: 7184047
    Abstract: Apparatus for generating computer models of individuals is provided comprising a booth (1) that is connected to a server (2) via the Internet (3). Image data of an individual is captured using the booth (1) and a computer model corresponding to the individual is then generated by comparing the captured image data relative to a stored generic model. Data representative of a generated model is then transmitted to the server (2) where it is stored. Stored data can then be retrieved via the Internet using a personal computer (4) having application software stored therein. The application software on the personal computer (4) can then utilise the data to create graphic representations of an individual in any one of a number of poses.

    Abstract: A special effect image generating apparatus provided with an image conversion processing circuit for posterization or other image conversion, a luminance and chroma condition setting circuit for image extraction by luminance and colors, a mask pattern generator for selection of a mask, and mixer for preparing a video signal, a transformation unit for transformation processing such as movement, and a post video modification unit for addition of a locus etc. The extracted image automatically tracks movement of the image so there is no change in visual effects, images having the same luminance and color conditions can be deleted by mask adjustment, movement of the image can be handled by adjustment of the mask, and highly accurate boundaries can be set by the wave-filtering and shaping circuit. Therefore, a special effect image with distinctive luminance and color can be easily prepared.

  • Patent number: 7006155
    Abstract: A system for forming composite video images from one or more foreground images and one or more background images. In one embodiment, s sum of a suppressed foreground image signal with weight ?, with one or more selected foreground colors suppressed, and a background image signal with weight 1??? (0????1) is formed, where a and ?? may vary from pixel to pixel and with time. In another embodiment, a shadow from a selected foreground image is impressed on selected pixels of a background image. In another embodiment, foreground suppression and shadowing are combined, optionally by retrofitting, using an existing ?-mixer or a newly constructed ?-mixer. Provision of a chroma key map allows a foreground image shadow to be prescribed pixel by pixel, including a transition region in which the shadowed image slowly disappears.

  • Publication number: 20040218100
    Abstract: An interactive video compositing device includes a chroma-key mixer, video switcher and control circuitry. The chroma-key mixer generates a composite image by combining a real-time image, such as one captured by a video recorder, with a prerecorded video image, such as a movie. The composite image includes the modified real-time image superimposed, or overlaid, onto the prerecorded image. The video switcher automatically selects either the composite image or the prerecorded image to be output to a display. The control circuitry controls the video switcher and other outputted signals based on data file information that corresponds to content of the prerecorded image or media. For example, the data files may contain information relating to the presence (or absence) of a particular character in a movie scene, thus allowing for the output and display, at appropriate times, of the real-time composite image instead of the prerecorded image.
