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.

Stereoscopic display method and apparatus therefor

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.

Color image data processing method

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.
