Apparatus and method for the colorimetric detecting of colour control fields in the case of the display device colour calibration defines of the output colors of electronic image processing systems

摘要

the faithful color reproduction in the electronic image processing need to calibrate the since many farbkontrollfelder with high time and labor fotometrisch ausgemeneed.often, therefore, again on the calibration of the einzelgeru00e4tes waived and its properties by average properties of devices of the same type are described.the dispersion of the individual devices is considerably.the invention is intended to facilitate calibration of the einzelgeru00e4tes by the measurements of the farbkontrollfelder automatically and with low apparativem effort is made.this is the $a bilddigitalisierer (scanner) of the bildverarbeitungssystems in its photoelectric method in addition, a special arrangement of kantenfiltern for spectral decomposition of deit meu00dflichtes. farbkontrollfelder band in the calibration by this filter, spectrally measured.the relative movement of the optical measurement of the scanner to produce with the farbkontrollfeldern is used to automate the process.$a calibration of since of electronic bildverarbeitungssystemen in the production process of printing units and farbkopiergeru00e4ten.
