Abstract: There is provided a method for preventing the occurrence of abnormal behavior such as cannibalism, fright behavior and collision death during rearing, storage and transportation of tuna of larva, juvenile and young adult fish stages, particularly, of those periods in the seed production. The abnormal behavior during rearing, storage or transportation of tuna is prevented by controlling their visual stimuli, particularly, by making wall and bottom surfaces of a rearing water tank coming with contact with the environment transparent, setting a visual stimulus-buffering material through which light transmits partially in both straight and diagonal directions, maintaining the tuna in the presence of colored fine particles in the environment, or controlling the fluctuation in illumination of the environment, or a combination thereof. Alternatively, death of tuna due to collision with a rearing water tank wall is prevented by stimulating their visual sense.

Abstract: 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.

Abstract: 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).

Abstract: 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.

Abstract: A plurality of different kinds of information, for example, full-color photographic image information and attribute information such as a name, date of birth, etc., are input by use of a CCD scanner (1a), a camera (1b), a keyboard (1c), a mouse (1d), etc., with coordinate information assigned to each piece of information. The input pieces of information are matched with each other with reference to the coordinate information, and an arrangement of the coordinated information is determined with reference to layout information prepared separately, and then the information is printed out onto a card substrate. Thus, an ID card can be made accurately and efficiently. In addition, forgery prevention processing is applied by simultaneously inputting forgery prevention information and further falsification prevention processing is applied by carrying out emboss processing, thereby enabling an improvement in the security of the ID card.

Abstract: 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.
