    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.

    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.
