发明名称 Multispectral color image pickup system
摘要 A method and apparatus for color stimulus specification-correction, i.e. sensation-correction pickup for scanning of chromatic image originals, referred to in short as a multispectral scanner. A color image pickup system is provided, based on the multispectral principle, the plurality of I>>3 narrow-band spectral filters and one black filter being introduced into the optical beam path of the image scanner, and thus I narrow-band spectral separations of a color image original and of a white image original are registered and digitized. Spectral pixel samples individually calibrated for all pixels are formed with an electronic evaluation unit in pickup real time. These are either stored in I parallel image storage levels or are multiplied by specific coefficients from a table in pickup real time of the signals in three parallel channels and are accumulated in three parallel image storage levels.
