摘要： A temporally recursive chrominance signal noise reduction can be achieved by subtracting a delayed version of the chrominance output signal from the chrominance input signal and by multiplying the related difference signal by a variable share factor and adding the resulting signal to the chrominance output signal, for achieving different degrees of noise reduction. From the difference signal a motion representative value and a value representing the presence of a smear effect are calculated and used to calculate the variable factor. After having been multiplied by this factor, the difference signal is combined with a frame-delayed version of the chrominance output signal in order to form the noise-reduced chrominance output signal.

摘要： The invention relates to a method for processing video pictures for display on a display device having a plurality of luminous elements corresponding to the pixels of a picture wherein the time of a video frame or field is divided into a plurality of N sub-fields during which the luminous elements can be activated for light emission in small pulses corresponding to a sub-field code word of n bits used for coding the p possible video levels lighting a pixel, comprising the steps of: determining if pictures are static pictures or moving pictures, in case of static pictures, processing video pictures using a first sub-field encoding method adapted to pictures when no motion is detected, and in case of moving pictures, processing video pictures using a second encoding method reducing dynamic false contour effect adapted to pictures when motion is detected. The invention applies to plasma display panels.

摘要： In a method for reproducing colour images by sequentially reproducing monochromatic images the monochromatic images are reproduced by projecting respectively filtered multispectral light onto an imaging device. In a sequence of changeable filters three different primary colour filters and three corresponding secondary colour filters are arranged in such a way that primary colour filters are arranged adjacent their respective complimentary secondary colour filter. Different brightness values are achieved by the imaging device passing on light to a screen as light pulses of corresponding different duration. White light is produced by subsequently illuminating a secondary and a corresponding complementary primary colour segment during corresponding time durations.

摘要： A method, apparatus and system for synchronizing between two recording modes includes identifying a common event in the two recording modes. The event in time is recognized for a higher accuracy mode of the two modes. The event is predicted in a lower accuracy mode of the two modes by determining a time when the event occurred between frames in the lower accuracy mode. The event in the higher accuracy mode is synchronized to the lower accuracy mode to provide sub-frame accuracy alignment between the two modes. In one embodiment of the invention, the common event includes the closing of a clap slate, and the two modes include audio and video recording modes.
