Abstract: A method for manufacturing a ceramic sintered body substrate includes of disposing a first metal paste on a surface of a ceramic substrate, and of firing the ceramic substrate on which the first metal paste is disposed. In the disposing the first metal paste, the first metal paste contains a plurality of first metal powders, a plurality of active metal powders, and a plurality of inorganic fillers excluding metals, and in the firing the ceramic substrate, a firing temperature is equal to or higher than a melting point of the first metal powders.

Abstract: A method and apparatus for printing a multivalue image in a binary-form output pattern. The printing apparatus employs a binary-form dither matrix pattern which is composed of a greater number of pixels, so that moiré patterns and other artifacts are minimized in printouts. The method includes: providing the binary-form dither matrix pattern for use in obtaining the binary-form output pattern; expanding the multivalue image in a memory area; and forming a binary image of output dot elements in accordance with the binary-form output pattern. The binary-form dither matrix pattern has a rectangular pattern in which a plurality of pattern elements that are numbered to be successively turned on are arranged in matrix. The turning-on sequence is set in such a way that plural groups of prospective output dot elements, which groups are substantially identical in shape, grow successively from a plurality of local points associated with the respective groups.

Abstract: A method is provided for creating a binary-coding pattern to be used in binary-coding a multi-value image. The method includes the steps of: creating a basic pattern shape of the prospective binary-coding pattern by a first arithmetic operation; determining the sequence of lighting pixels composing such basic pattern by a second arithmetic operation; and creating a rectangular pattern, which serves as the prospective binary-coding pattern, based on the resultant basic pattern. Hereby, it is possible to automatically create a centralized type of binary-coding pattern, and also it is possible to facilitate creating a minimum-sized binary-coding pattern.

Abstract: Present invention relates to a color image processing apparatus including an input color chip making unit for making a color chip of the selected color signal as an input color chip, an output color chip making unit for subjecting the selected color signal to the under color removal processing carried out in an UCR processing unit with two or more parameters different from one another, thereby making a color chip of the obtained color signal as an output color chip for each parameter, and a parameter determining unit for selecting among the parameters a parameter which provides the minimum difference between the input color chip and the output color chip, wherein the UCR processing unit subjects the input color signal to the UCR processing by using the parameter selected by the parameter determining unit. With this, a color image desired by a user can be created.

Abstract: A conversion parameter computing section computes conversion parameters corresponding to a position included in a partial space with one edge thereof equal to w/2 (where w is a lattice interval). When L*a*b* value for an input color is inputted, an intra-lattice position computing section computes a position in a lattice space identified by a lattice point identifying section using a conversion table. An interpolation section outputs CMY values corresponding to L*a*b* value by executing interpolation according to conversion parameters retrieved by a conversion parameter retrieving section.

Abstract: In addition to linear conversion parameters V1 to V8 which are used in an interpolation calculation, non-linear conversion parameters VV1 to VV8 are calculated. Each time an input color is fetched, whether the linear conversion parameters are used or the non-linear conversion parameters are used is discriminated. The interpolation calculation of a high precision using the non-linear conversion parameters is performed for a region where it is necessary to guarantee a gradation, thereby preventing a reversal of an output color in a region including an achromatic gradation axis. Regions other than such a region are processed by the interpolation calculation using the linear conversion parameter at a high speed.
