Abstract: For an imaging method for presenting fluorophores (5) by optical excitation, spontaneous emission of fluorescence and detection of same, a single, conventional sensor (6) is used having at least two color channels, which detect an excitation light used to excite the fluorophore (5) and the fluorescence emitted by the fluorophore (5) with different sensitivities. Due to the different spectral distribution of the sensitivity of the color channels, it is possible to separate the component of the excitation light from the component of the fluorescence, in particular in a specific pixel, from one another by processing output signals of said color channels, in particular by conversion into a color space and/or by calculation of color saturation values. From this, the intensity of the fluorescence can be deduced, preferably taking account of a relative luminance measured by the color channels, even though reflected excitation light reaches the color channels, in particular in an unfiltered manner.

Abstract: 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.

Abstract: 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.

Abstract: 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.
