    摘要: An imaging device condition determination section determines whether a condition of an imaging device is suitable for obtaining light source information. When it is determined to be suitable, a light source image obtaining section obtains a light source image by the imaging device. A first imaging device information obtaining section obtains first imaging device information representing the condition of the imaging device at a point in time when the light source image is obtained. A second imaging device information obtaining section obtains second imaging device information representing the condition of the imaging device at a time of actual image capturing. A light source information estimating section estimates light source information at the time of image capturing by using the light source image and the first and second imaging device information.

    摘要: An interpolated image obtained by enlarging and interpolating an image (IN) is subjected to predetermined vector transformation to calculate an image feature vector. Also, a characteristic of a subject is obtained to calculate a physical characteristic parameter of the interpolated image. The physical characteristic parameter is used to transform the image feature vector to sharpen the interpolated image. The transformed image feature vector is subjected to transformation inverse to the predetermined vector transformation to generate an enlarged image (ELI).

    摘要: When an image inputted is displayed on the display, determined is an enhancing degree as a parameter for enhancing the sharpness of the input image by using at least one of information about a subject included in the input image and information about the display for displaying the input image. By using the enhancing degree determined, color distribution is controlled on a first principal component analysis axis obtained by analysis based on a principal component analysis in a color space. Furthermore, the texture of the subject is magnified in size and again mapped onto the subject. Due to this, the input image can be enhancement-processed to a well texture feeling easy to view.

    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.
