  • Patent number: 7602441
    Abstract: Fuzzy logic based system and method for 3:2 pull-down film mode detection that detects whether a stream of NTSC video fields originate from film source via 3:2 pull-down technique. Fuzzy logic is used to generate a reference sequence of symbols from the stream of NTSC video fields. This reference sequence is adapted for indicating whether or not the video fields originate from film source.

  • Publication number: 20090238224
    Abstract: A DBR laser, such as a semiconductor DBR laser is disclosed having improved frequency modulation performance. The laser includes a split gain electrode and a tuning electrode. A modulating current encoding a data signal is injected into a first section of the gain electrode whereas a substantially DC bias voltage is imposed on a second section of the gain electrode positioned between the first gain electrode and the tuning electrode. The first and second gain electrodes are electrically isolated from each other and the tuning electrode by a large isolation resistance. In some embodiments, the isolation resistance is generated by forming the electrodes on a P+ layer and removing portions of the P+ layer between adjacent electrodes. Capacitors may couple to one or both of the second gain electrode and the tuning electrode.

  • Patent number: 7515204
    Abstract: A method and system for performing fuzzy logic based de-interlacing on film source fields that might be mixed with video on film. An embodiment of the invention comprises an adaptive de-interlacer by weighing between merge operation and interpolation operation in the case of occurring video on film motion object. A weighing factor is generated from video on film pattern based on fuzzy logic inference rules. This weighing factor specifies the weighting between merging and interpolating in assigning the pixel values of the progressive display output.

  • Patent number: 7502529
    Abstract: To interpolate a value for a pixel, multiple patterns are selected. Each pattern is used to determine a pixel angle. One of the determined pixel angles is then selected based on the reliability of the pixel angles. The selected pixel angle can be selected based on its reliability irrespective of the reliability of other pixel angles. The selected pixel angle can then be used to interpolate a value for the target pixel. Dynamic thresholds can be computed for use in either determining a pixel angle for a given pattern, or to select the pixel angle from the available determined pixel angles.

  • Patent number: 7443370
    Abstract: A boost table stores adjusted target levels for pairs of original and target pixel levels. The adjusted target levels can be used to as a substitute for the target pixel level to improve pixel response in reaching the desired target pixel level. A reduced boost table can be used, storing a subset of the adjusted target levels. Fuzzy logic control rules can be used to calculate adjusted target levels not actually stored in the reduced boost table.

  • Patent number: 7427993
    Abstract: A compressed pixel level for a pixel in a frame of an image is compared with the (compressed) pixel level for the same pixel in a previous image frame. If the pixel level is unchanged, then the pixel is not moving. An uncompressed pixel level is then used for that pixel in the current image. If the pixel level is changed, then the pixel is moving, and a decompressed, boosted pixel level is used for that pixel in the current image.

  • Publication number: 20080193144
    Abstract: The frequency chirp modulation response of a directly modulated laser is described using a small signal model that depends on slow chirp amplitude s and slow chirp time constant ?s. The small signal model can be used to derive an inverse response for designing slow chirp compensation means. Slow chirp compensation means include electrical compensation, optical compensation, or both. Slow chirp electrical compensation can be implemented with an LR filter or other RF circuit coupled to a direct modulation source (e.g., a laser driver) and the directly modulated laser. Slow chirp optical compensation can be implemented with an optical spectrum reshaper having a rounded top and relatively large slope (e.g., 1.5-3 dB/GHz). The inverse response can be designed to under-compensate, to produce a flat response, or to over-compensate.

  • Patent number: 7292738
    Abstract: A method and system for image resample by spatial interpolation. The method and system allow more than simple angle interpolation by allowing spatial interpolation to be performed on small angle edges. Multiple interpolation directions are established. Once an interpolation direction is selected, verifications are performed on the selected interpolation direction in order to rule out erroneous selection. If the selected interpolation direction passes all verifications, then spatial interpolation will be performed along the selected interpolation direction. Otherwise, a default interpolation direction is used as the interpolation direction.
