摘要： PURPOSE:To improve the input efficiency of line and surface data and to add these data to a stereoscopic picture for surface model display with correction, by producing simultaneously both line and surface data related with each other for each point when the 3-surface diagram data is produced. CONSTITUTION:A 1st coordinate surface XY is chosen among those three coordinate surfaces XY, ZY and XZ by a stylus 3. Then the surface XY is displayed on a screen 29 in a 3-surface diagram production mode. When the stylus 3 is set on a coordinate area 2a of a table surface, a cursor is displayed on the screen 29. A surface attachment designation mode is set with push of a closed loop surface designating area. When a connection point key is pushed by the stylus 3, the relationship is secured by a data production means 21 between surface and line data for input of a data number, a surface number, an apex number, the XY 2-dimensional coordinates and attributes. When the input is through with all line and surface data, a perspective projection pattern of the surface XY is inputted. Then the surfaces ZY and XZ are selected to proceed to the next process and all data on X, Y, and Z are decided. Thus the projected pattern of the surface XZ is displayed at a time.

摘要： PURPOSE:To emit lights from light emitting elements which are uneven in interval to the outside from positions which are even in interval. CONSTITUTION:Lights from light emitting elements 14 in a glass case 16 are emitted to the outside through an optical fiber layer 21 in contact with the upper side of the glass case 16. The optical fiber layer 21 is sectioned in an S shape and has its projection surfaces deviating from its incidence surfaces aligned with the light emitting elements 14 laterally or longitudinally by specific distance. Further, the projection surfaces of the optical fiber layer 21 are arranged at the same intervals P including the optical fiber layer 21 at the border parts of cells 13. Consequently, even if lateral intervals PO and P1 of the light emitting elements 14 are uneven, the lights from the light emitting elements 14 can be emitted to the outside at the same intervals. Consequently, a image on a large-sized video device can be made homogeneous. Further, an optical fiber layer 21 which is large in NA is used to obtain a wide visual field angle.

CONSTITUTION:A projector 2 projects a menu comprising plural items for adjustment onto a screen 6 based on a video signal from a picture generator 5 having a function as a menu generator and an optional item is selected among the items for the adjustment in the projector remote controller. A laser beam stimulated from a laser pistol 7 radiates a desired item and a radiating items position P is detected by an image pickup device 1 and a picture generator 5 makes relevant adjustment based on the output of the image pickup device 1.

摘要： PURPOSE:To obtain a stable color index signal even a screen is at a black level by mixing an UV laser beam and an infrared laser beam, irradiating/ scanning a screen with the mixed beam, and converting the infrared beam reflected by a reflector to an electric signal by a photodetector. CONSTITUTION:The UV laser beam generated from a light source 1 is made incident on a light modulator 12 and is modulated by a color image signal; moreover, the UV laser beam is made incident on a polarizing beam splitter PBS 19 through an expander 13 constituted of such as a concave lens and a focal lens. An IR laser beam and the UV laser beam which are made incident on the PBS 19 are polarized linearly. If the UV laser has P polarizing component and the IR laser beam S polarizing component, 100% of the P polarizing component of the UV laser beam passes through the PBS 19. S polarizing component of the IR laser beam is reflected by the boundary surface of the PBS 19 and becomes a mixed laser beam 16. The screen 4 is irradiated with the mixed laser beam 16. In this normal beam, the visible light phospher normally emits, and excitation corresponding to the black level is transmitted without affecting the visible light phospher at the black level.

摘要： PURPOSE:To narrow down the vertical directivity of a reflection type screen and to widen the horizontal directivity by arranging glass or plastic rods on a diffuse reflecting layer horizontally in parallel. CONSTITUTION:The reflection type screen 1 is manufactured by sticking many tapes 3 in array on one surface of, for example, a large-area screen substrate 2 so that breadthwise end parts of the tapes 3 contact each other and the lengthwise direction is perpendicular to the screen 1. Then the tape 3 is formed by adhering the glass or plastic rods 5 so that the width direction of an adhesive tape 4 is horizontal and silver powder is mixed with the cohesive layer of the tape 4 to form the diffusion layer on the adhesive layer on the reverse surfaces of the rods. A light absorber is charged between rods 5 to improve the contrast.

摘要： PURPOSE:To remove the variation in time of pictures when video signals from two, right and left, TV cameras are double-speed converted and multiplexed by setting a time difference of 1/2 vertical period between the synchronizing signals of the cameras. CONSTITUTION:This stereoscopic video device is constituted in such a way that two sets of TV cameras 1L and 1R are provided and the synchronizing signal of one TV camera is delayed by 1/2 vertical period (Circuit 2) against the synchronizing signal (reference) of the other camera and video signals from the cameras 1L and 1R are respectively written in memories 4Lo, 4Le, 4Ro, and 4Re, and then, multiplexing signals are obtained by reading out (control circuit 5) the memories at double speed. Since the time difference of 1/2 vertical period is set between the right and left pictures at the time of photographing, no variation in time is produced in the pictures when the video signals of the pictures are double-speed converted and subjected to multiplex circuit. Therefore, unnaturalness in the movement of the pictures can be dissolved.

摘要： PURPOSE:To obtain many colors with a small number of memories by providing a storage means for storing frames wherein picture element data of a still picture signal are all '0' and all '1' and a storage means for storing the contents of frames wherein '0' and '1' coexist by bits. CONSTITUTION:A digital signal is written in 8-digit memories 31-38 and nine bit memories 71-79 constituting an image memory device 3. In this case, only codes of bits '1' and '0' which are present in one frame are written in the memories 31-38 having one-frame picture-element capacity and only '1' or '0' is written in the memories 71-79 in one-bit units as to bits of one frame wherein codes are all '1' or '0'. For example, 8-bit picture element data obtained from one still picture by an input check and control circuit 8 is as shown in a figure. In this case, bits of one frame where codes are all '1' or '0' are written in the memories 71-79 as representative '1' or '0'. Consequently, 6-bit data can be made effective for a G and an R signal.
