摘要： PURPOSE:To easily adjust a feeling of reality in matching for user's taste by controlling and varying the physical or spatial conditions of a body to be displayed in a three-dimensional scene with a single parameter. CONSTITUTION:When data for forming a computer graphic(CG) image are inputted from an input editing device 11, the CG image is displayed on a display 13 through a controller 15 and a computer 12. In this state, the single parameter is inputted from the input device of a reality feeling controller 16 to adjust the feeling of reality according to the user's taste. This single parameter is so constituted that respective parameters of the attributes of the color, transparency, surface pattern etc., of a body in the image satisfy a specific function relation. Consequently, the feeling of reality can be adjusted according to the user's taste. Further, automatic control can be performed by detecting the perspiration amount, pulsation, etc., of the user.

摘要： PURPOSE:To record and reproduce the different types of information via the same recording medium by recording the digital TV picture information, the digital voice information, the object information transformed into a language, etc., onto the same recording medium and discriminating these information after reproduction. CONSTITUTION:The object information on a 3-dimensional position transformed into a language as well as the compressed digital TV picture information and the digital voice information are recorded on the same recording medium. These recorded information are read by a recording medium reading part 11 and a language transformation data deciding part 12 decides the recording contents are equal to the language data or not. If not, the read data is expanded and restored by an information restoring part 14 via one of two changeover switches 13 and delivered via a D/A converter 16. While the language data is stored in a language data memory 17 via the other switch 13 and converted into the digital picture data via a position information converting part 19, a language raster converting part 20, etc., to be stored in a picture memory 15. Thus the different types of information like the digital information, the language information, etc., are recorded and reproduced via the same recording medium.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for deciding the moving state of a mobile object, without using acceleration sensor. SOLUTION: A receiver 1 receives electromagnetic waves transmitted from transmission equipment 8 by using an antenna 2, and a measuring means 3 measures the electric field strength of the electromagnetic waves. A particular pattern is decided by using an analyzing device 4 for analyzing and deciding the temporal change of the measured electric field strength because the particular pattern occurs in the temporal fluctuations of the electric field strength when a mobile terminal 7 is moved, and an outputting means 5 outputs these decision results. The mobile terminal 7 is provided with a communication function and can thereby decide the moving state of the mobile object at a remote place.

摘要： PURPOSE:To easily arrange many graphics in a determined area of a graphic by arranging a graphic in a closed area at a position based upon the probability density in the closed area. CONSTITUTION:An input device 120 inputs the graphics to be arranged in the closed area, and coordinate values and density in the closed area, a circumscribed rectangle generating device 121 generates the circumscribed rectangle from the closed area, and a random number generating device 122 generates two-dimensional random numbers in the circumscribed rectangle. An inside/ outside decision device 128 for the closed area decides whether the generated random numbers are inside or outside the closed area and inputs data in the area to a graphic arranging device 126. Further, a depth information storage device 125 stores distances to the graphics projected on a screen, pixel by pixel. Then the graphic arranging device 126 arranges the graphics in three dimensions by referring to height information corresponding to two-dimensional position information for arranging the graphics in the depth information storage device 125, thereby displaying the respective graphics as three-dimensional computer graphics by using a display device 127.

摘要： PURPOSE:To control the structure composed of many joints like a man using a computer graphic by controlling the parameter of an motion expression time function. CONSTITUTION:A coefficient of the time function corresponding to each joint of a human for the type of motion is registered in an motion expression time function database 11. A joint angle arithmetic device 12 calculates a bent angle in a certain time of each joint of a man. A rendering device 13 projects the three-dimensional location and figure of the man to be projected to two- dimension. A display device 14 displays the projected result on a display. A controller 15 performs the selection of the time function of the motion expression time function database 11, the correction of the coefficient of the selected time function, and the control of a time variable (t). Therefore, the selection of the motion and the motion expression other than the motion stored in the database, and the motion speed by the control of the time variable (t) are controlled.
