摘要： A display device comprises revolving coloured wheels, so as to generate a periodic coloured beam, and an imager which modulates the coloured beam as a function of a received video signal. The coloured beam (8) takes successively at each period a plurality of primary colours in synchronism with the images generated by the imager for each primary colour. By adjustment of the relative position of the coloured wheels, it is possible to modify the hue of the primary colours so as to best match them to the received video signal.

摘要： What is proposed is a method for the color correction of digital image data generated by spectral absorption of white light in color filters of a first representation means. Color film material, in particular, is taken into consideration as the first representation means. For this purpose, firstly the primary color values R, G, B of the image data on the color film are detected. Said primary color values R, G, B are corrected in order to generate secondary color values R′, G′, B′ which are related to a second representation means, for example a monitor. This correction involves taking account of the absorption of light in secondary densities of the colorants of the film material which form the color filters of the first representation means. For this purpose, a plurality of absorption spectra are generated for different densities of the colorants. Finally, the spectral profile of the absorption spectra of the colorants influences the correction of the primary color values for generating the secondary color values. This follows the aim of achieving a maximum correspondence between the color representation with the first representation means and the color representation with the second representation means.

摘要： A method for image processing of digital image pixels. Pixels are preferably filtered spatially and dithered, and the value for at least one color component is bit reduced. The space freed by the bit reduction is used to allocate a look-up table selection bit that indicates which look-up table (LUT), from a plurality of small LUTs partitioned from a bigger LUT, should be used for the color transform. The transformed pixels are then selected according to the used LUT, format converted and output. The invention, which also covers an apparatus and a pre-processing module, enables an apparatus with a LUT to be used both as a single full-rate LUT apparatus and as a lower-rate n smaller LUT apparatus.
