An abstract pattern plate-making system removes an undesired pattern from an endless pattern in the process for making a plate for printing abstract patterns on architectural materials. For this purpose, it has a scramble processing part 10 and a pixel copy processing part 11. The scramble processing part 10 divides endless pattern data into blocks and repeats processing in which pattern data in two blocks selected at random from among the divided blocks are combined together by a composition technique using mask data having a predetermined pattern, thereby removing an undesired pattern. The mask pattern size may be either smaller or larger than the block size. The mask pattern may be a multi-valued pattern. Further, when the endless pattern is divided into blocks, the blocks may be allotted so as to be a little offset from the endless pattern. The pixel copy processing part 11 first prepares mask data on the basis of designated pattern data in the endless pattern data and then repeats processing in which pixel data at a designated position is copied to another designated position on the basis of the prepared mask data, thereby removing an undesired pattern.

A hologram seal for security is prepared in pseudo manner by using a diffraction grating pattern. A picture data of a plurality of motifs is inputted to a computer. Within the computer, there are prepared in advance plural kinds of pixel patterns in which grating lines are arranged within one pixel at a predetermined line width, a pitch and an arrangement angle. These pixel patterns are arranged in a matrix form like tiles by making reference to the inputted picture data to represent respective motifs. The picture data in which the motifs are represented is given to an electron beam picture drawing apparatus to prepare a diffraction grating original block. This original block is used to mass-produce pseudo hologram seals by press device. By varying an arrangement angle of grating lines, it is possible to carry out gradation representation, or to record a plurality of motifs in an overlapping manner.

A method and system for making a baby-plate for use in printing abstract patterns on architectural materials wherein glitches are easily confirmed and removed. A unit material is read by an input scanner (1) and the image digitized into pixels of given density. The image data of the unit material is dissolve-composited repetitively M times vertically (M being a positive integer) and N times horizontally (N being a positive integer) in an endless processor (9) to construct pattern data of given size. Some pixels are culled from the pattern data by a glitch-checking processor (10) for creating reduced pattern data for display on the screen of a monitor (14) for determining the presence of an undesired pattern, i.e., a glitch, by viewing the screen of monitor (14). If there is a glitch, then the glitch is removed by a glitch removal processor (11). The glitch removal processor (11) operates according to three schemes--scramble, pixel copy and Fourier transform--depending on the state of the glitch for providing effective and efficient glitch removal.

A computer graphic image generating apparatus for generating an image based on a computer graphic model including shape information, camera information, camera position information, object position information, texture information, light source information and mapping information which includes texture image information. The apparatus includes a storage device, or memory, and means for calculating the amount of space in the storage device required to store all the information used to generate an image. The apparatus also includes means for storing the information for an image in the storage device without wasting any storage space. The apparatus also includes means for converting image information created for a first image generating system having a first shading calculation system into image information usable on a second image generating system having a different shading calculation system. The apparatus may also include means for converting image information usable by the first system into an interface format so that the image information can then be converted into a format usable by the second system.

Computer graphic image storage, conversion and generating apparatus

An abstract pattern plate making system comprising a grain pattern generator for generating grain patterns free of unintended repetitive patterns. When an image size, a grain count, maximum displacement amounts and a grain shape are input, the grain pattern generator generates the basic addresses of the designated number of grains in such a manner that the grains occur at equal and uniform intervals in the designated image size and that the number of grains per unit area remains constant. The address of each grain is then displaced relative to its basic address with the designated maximum amounts of displacement. The designated grain shape is assigned to each of the displaced addresses so as to generate a grain pattern. If the address of any grain protrudes out of the designated image size, the grain pattern generator transfers the protruding pixel to a location opposite to the protruding side so as to keep the grain within the designated size.
