Abstract: A process for fabricating a color filter comprising a support and a color element layer comprises irradiating a coloring matter with an energy ray modulated by a pattern mask to melt or sublime the coloring matter and applying selectively the coloring matter to the support corresponding to the modulation to form the color element layer.

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: An image signal processing method and apparatus for practicing the method are capable of identifying and differentiating information not having tonal rendition such as characters and linetone images from information having tonal rendition such as photographs and pictures, based on the difference of signal characteristics, for example based on the fact that the spatial frequency distribution in portions of an image not having tonal rendition are in the higher frequency range compared to that of the portions of the image having tonal rendition. The method and apparatus are also capable of conducting different processes on the identified different images.
