摘要： A color correction method applicable to a digital processing type of color copier, whereby a set of color patches of respectively different sample colors is printed using a set of printing data values, the color patches are then scanned and analyzed to obtain color patch input data values by the color copier, and each of all of the possible input color data values that can be produced by the scanner/analyzer section of the color copier is then related to one of the color patch input data values which is closest thereto in a 3-dimensional color space. Each of these possible input color data values is thereby related to an appropriate color printing value, whereby a color correction table can be generated which provides correction accuracy that is independent of non-linearity of color printing characteristics.

摘要： A color print painted with different colors C.sub.i (i = 1, 2 . . . n) is scanned by a color scanner along a plurality of successive line paths to generate a set of electrical signals each representing the intensity of the spectral components of the light reflected from an elemental area of the print. A macroscopic color separator is provided to generate a set of electrical signals each representing the average spectral intensities per unit area of the print. A data processor is used to compute the probability P(C.sub.i) from the data obtained from the macroscopic color separator and a set of mean spectral intensities exhibited by the color samples with which the print is painted by artisans. In accordance with the Bayes' Rule, the processor then executes computation of the product of P(C.sub.i) and the conditional probability of occurrence of elemental color spectral intensities given that the elemental area being scanned belongs to a particular color sample, using the data received from the color scanner as it scans the print.

摘要： A two-valued object such as black-and-white textural or pictorial material is repeatedly scanned aong each of a plurality of line paths within the object to produce an image signal which is representative of a series of black and white runs or areas within the line path. The length of black or white run or "run length" is sampled by clock pulses and translated into a binary code and transmitted bit by bit at the line scan rate to a receiver station. A vertical sync pulse is inserted at the end of the (n-1)th run length wherein n represents the number of run lengths within the image signal so that the last run length is skipped. The last run length so skipped at the transmitter is reconstructed at the receiver during the time interval of the vertical sync pulse.

摘要： A color converting apparatus is provided with a table memory for storing pieces of color converting data defined in an output color space at color converting addresses, and a signal receiving section for receiving three signals designating an input color in a lightness-color difference space. The color converting addresses are placed at lattice points of cubic blocks formed by partitioning the lightness-color difference space in a lightness direction and first and second color difference directions. Each of the cubic blocks has the lattice points Pa, Pb, Pc and Pd at its lower plane and the lattice points Pe, Pf, Pg and Ph at its upper plane. Each of the cubic blocks is partitioned into a first triangular prism having the lattice points Pa, Pb, Pc, Pe, Pf and Pg and a second triangular prism having the lattice points Pa, Pd, Pc, Pe, Ph and Pg. A particular triangular prism in which the input color is included is specified, and six pieces of color converting data Da, Db (or Dd), Dc, De, Df (or Dh) and Dg addressed at the lattice points Pa, Pb (or Pd), Pc, Pe (or Ph), Pf of the particular triangular prism are read out from the table memory, and an output color which corresponds to the input color and is defined in the output space is interpolated with the color converting data read out.

摘要： A color value correction apparatus for converting each of successive combinations of input tricolor digital values into an output color value in accordance with predetermined data stored in memory, includes three table memories which store values which are respective differences between color values corresponding to vertices of unit tetrahedra in a color space and a reference color value that is common to all of a set of tetrahedra forming one of an array of unit cubes or parallelepipeds which constitute that color space, and also includes a table memory that stores these reference color values. To obtain an interpolated output value, each of these memories is addressed three-dimensionally by the high-order bits of an input tricolor value combination to thereby specify one of the unit cubes or parallelepipeds, and the difference value memories are in addition addressed by a value, derived from the low-order bits of the input value combination, specifying a specific tetrahedron containing the interpolation point. An interpolated output value can thereby be obtained by executing only three multiplication operations followed by addition operations.

摘要： A color conversion apparatus is described whereby color within at least one specific region of a color picture can be converted to a different color in a reproduced picture, while enabling gradations of color and lightness within that region to be left substantially unchanged. The conversion is based upon setting of pre-calculated output values in a table memory within a color conversion section, by an initialization operation, and conversion can be a change in one color attribute or in a combination of attributes of respective color values within the selected region. The table memory subsequently responds to successive input color values supplied thereto by producing color-converted output values which can be supplied for example to a color printer apparatus, with resultant degrees of color change being determined in accordance with degrees of closeness of one attribute or a combination of attributes of each input color value to the corresponding attribute or combination of attributes of a predetermined color value.
