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 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.

摘要： The present invention relates to a method and apparatus applied to a widely-used and high-speed color conversion which is utilized in a color printer, a color display apparatus and the like, and provides a novel three-dimensional interpolation operation by use of a triangle-pole shaped interpolation unit-space. Input color signals R,G, and B are converted into lightness signal Y and chromaticity signals Cr, Cb which constitute a three-dimensional space. This three-dimensional space is dissected into rectangular parallelopipeds and is further divided into two prisms having base planes parallel to the chromaticity plane CrCb. A prism judging section 207 judges which of prisms an input color is involved in. There are provided a plurality of color conversion table memories 210.about.215 which store output values corresponding to input values constituting respective points of the prism and difference values of mutual output colors and further difference values of mutual difference values. Stored data in respective color conversion table memories 210.about.215 are weighted by lower-bit signals 205, 206 of the input color signals in multipliers 219, 220, 226, 227, and 230. Then, these data are added in adders 220, 221, 228, 229, and 231 so as to accomplish a linear interpolation using output values of six vertices which constitute the prism.

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 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： In one embodiment, an element 106 transforms non-polarized light into plane polarized light with an arbitrary plane of polarization. A synchronizer 112 gives the element 106 an instruction to rotate the plane of polarization, thereby getting the plane of polarization of the illumination rotated and casting that polarized illumination toward the object. At the same time, the synchronizer 112 sends a shooting start signal to an image sensor 110, thereby getting video. The synchronizer 112 performs these processing steps multiple times. A captured video signal is sent to an image processing processor 108. Candidates for the azimuth angle of a surface normal are obtained based on an intensity maximizing angle image, the zenith angle of the surface normal is obtained based on a degree of intensity modulation image, and the ambiguity of the azimuth angle is solved, thereby generating a surface groove normal image.
