摘要： The invention provides a printing system by which a greater number of pixels are used to form a basic pattern and moirés and artifacts can be reduced. A binarization dither matrix pattern is configured by arranging a plurality of pixels to be successively turned on in a matrix and has a plurality of specific points P1 and P2 provided at substantially point symmetric positions with respect to the position C of the center of figure thereof. Those of the pixels which are adjacent to be turned on pixels are preferentially turned on in order beginning with those of the pixels which are positioned near to the specific points P1 and P2 to individually form successive halftone dots. When a number of pixels substantially equal to one half the number of pixels which form the binarization dither matrix pattern are turned on in order, the turned on pixels and unturned on pixels form a checkered pattern in the binarization dither matrix pattern.

摘要： 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.

摘要： A technology of matching the real output color of a color printer with the color to be reproduced on a monitor by estimating spectral reflectivities precisely with consideration of an optical phenomenon peculiar to the color printer output. A coefficient calculating section calculates coefficients representing color characteristics of the color printer output and concerning the respective spectral reflectivities of 3 reference color chips for a side, which is neither a side where the dot-area percentage of black is 100% nor a side representing black gradation, based on the spectral reflectivities of the color chips. A spectral reflectivity calculating section calculates a spectral reflectivity corresponding to an arbitrary dot-area percentage on the side, based on the coefficients calculated by the coefficient calculating section, and in the meantime calculates a spectral reflectivity corresponding to an arbitrary dot-area percentage on the side where the dot-area percentage of black is 100%, based on the spectral reflectivities of the color chips. This technology is useful in reproducing the output of an electrophotographic color printer on a monitor, such as CRT, LCD or PDP.

摘要： An illuminance spectrum I of reflected light from a color print of an arbitrary dot percent d is defined by a diffuse reflection coefficient Sb(d,.lambda.) and a specular reflection coefficient Ss(d,.lambda.). The diffuse reflection coefficient Sb(d,.lambda.) is determined by linear interpolation of a plurality of reference reflection coefficients Sb(d.sub.i,.lambda.) for a plurality of reference dot percents d.sub.i. The specular reflection coefficient Ss(d,.lambda.) is also determined by linear interpolation of a plurality of reference reflection coefficients Ss(d.sub.j,.lambda.) for a plurality of reference dot percents d.sub.j. The illuminance spectrum of reflected light is then determined according to these reflection coefficients Sb(d,.lambda.) and Ss(d,.lambda.). Color data representing the colors of the print in a calorimetric system suitable for an output device are subsequently generated from the illuminance spectrum.

摘要： The present invention provides an improved technique for extracting contours in an image without waiting for processing of all the scanning lines in the image. Run-data on two boundary scanning lines, each representing the boundary coordinates at which the image changes, are stored in a run-data buffer. A contour extraction unit compares two sets of the run-data with one another to extract segment vectors and detect a set of closed-loop vectors defining a contour of a image area. Three registers in a working buffer store specific data representing the relationship between a starting point and a terminal point of each vector sequence and are used in detecting closed-loop vectors. A vector data memory stores vector data including coordinate values of start and end points of closed-loop vectors. The contour extraction unit detects a vector sequence which has a starting point identical with a terminal point as a function of the data registered in the working buffer to identify the vector sequence as a closed-loop.
