Abstract: The invention relates to a color image processing method and apparatus therefor, in which dot area ratio is decided when color printing is performed using inks of the four colors yellow, magenta, cyan and black.In color printing, in principle most colors can be printed by the superimposed printing of inks of the three colors Y, M, C.However, when performing color printing using four colors, inclusive of black, it is difficult to decide the dot area ratio of each color for the purpose of reproducing a target color, and excellent color reproduction cannot always be obtained even if printing is performed at the dot area ratios decided by the conventional method.Accordingly, the invention is adapted to decide area ratios A.sub.Y, A.sub.M, A.sub.C, A.sub.

Abstract: A lattice plate is arranged in front of and in a spaced relation from an image display screen. An image to be displayed is divided into pixels each of which is modulated to a grid having a grid interval determined by far-near information carried by the pixel. When a viewer views the screen through the lattice plate, he/she can view a steroscopic image.

Abstract: There is provided a color image data processing method for reproducing a color image by use of micro color points of a plurality of colors. The processings for every region to obtain the areas of the color points are performed in parallel irrespective of which region in a plurality of regions on the chromaticity chart the color which should be reproduced belongs to, and among the respective processing results, the color points whose areas were determined to be positive values are used, thereby reproducing a color image.

Abstract: A method of recording a color image uses both additive primary colors (that is, red, green, and blue) and subtractive primary colors (that is, cyan, magenta and yellow), as well as white and black. These eight colors are used to provide a dot matrix representing one picture element of the image, wherein each picture element is represented by a predetermined number of dots of an additive primary color, a predetermined number of dots of a subtractive primary color and, if appropriate, predetermined numbers of white and black dots. The dots do not overlap.
