摘要： PROBLEM TO BE SOLVED: To provide a linear relation between adjusting quantity and quantity of light by setting the adjusting quantity for adjusting the quantity of light, outputting a power proportional to a specified function on the basis of the set adjusting quantity, and reducing the inclination of the function according to the increase in adjusting quantity. SOLUTION: A remote controller 61 transmits an input signal to a receiving device 62. A regenerating device 86 regenerates the voice signal and dimming data recorded on a CD-ROM. A microcomputer(MC) 64 adjusts the luminance of each lamp 84 on the basis of the data from the regenerating device 86 and the receiving device 62, and also transmits a prescribed control command to the regenerating device 86 to control it. A memory 66 stores the offset luminance data of each lamp 84 and also stores the processing command and calculation data for the processing by the MC 64. A lamp driving device 75 amplifies the power of the electric signal from a digital dimming curve circuit 71. Lamps 81-83 convert the electric signal to color of red R, green G, or blue B, respectively.

摘要： PURPOSE:To generate a pointer mark easy to see through easy operation with simple constitution by projecting an infrared beam on a screen and detecting the position of a projection point, and superposing a corresponding pointer mark signal on an input image signal. CONSTITUTION:For example, an explainer indicates an optional point P in an image on the screen 1. At this time, the explainer projects the infrared laser beam on the optional point P on the screen 1 by a laser pointer 4. An image of the screen is picked up by an infrared camera 5, and a position detector 6 detects the position of the bright point P of the infrared rays on the screen 1 from the output signal of the camera. The detection signal is sent to a mark generation image processing circuit 7, which outputs a pointer mark signal; and a superposing means 8 superimposes the signal upon an input video signal and the image is projected on the screen 1 by a TV projector 2.

摘要： PURPOSE:To improve the utilization efficiency of a light beam and to improve the brightness of projection light by disposing specular surfaces to a light source and a polarization beam splitter and also arranging a lambda/4 plate between the light source and polarization beam splitter. CONSTITUTION:A specular surface 6 is provided behind the light source 1, a specular surface 7 is provided on the opposite surface of the polarization beam splitter 2 from the light source 1, and the lambda/4 plate 8 is provided between the light source 1 and polarization beam splitter 2. A light beam from the light source 1 is made incident on the polarization beam splitter 2, only the S wave component in the light beam is reflected to illuminate a liquid crystal valve 3, and the P wave component in reflected light which is made incident on the polarization beam splitter 2 again is passed, so that a light beam which accords with the light and shade of an optical image is projected on a screen 5 through a lens 4. Consequently, the utilization efficiency of the light beam is increased and the brightness of the projection light is improved.

CONSTITUTION:A video signal SRL subjected to time division multiplex by right/left channel video signal for one field each alternately is inputted to an input terminal 3, the signal SRL is fed to a synchronizing separator circuit 4, from which a horizontal synchronizing signal HD is separated and the right/left video signals SR, SL by the video portion from which the horizontal synchronizing signal is extracted are obtained alternately for one field each. The relative position between the video portion of the video signal of any channel and the horizontal synchronizing signal is adjusted to move at least either of left or right pictures 1R, 1L at the most proper position in the horizontal direction. Thus, the stereoscopic picture with a maximum reality is obtained without losing the stereoscopic sense.

摘要： PURPOSE:To ensure simple and accurate execution of input of the 3-dimensional coordinates by having input of points on a drawing onto a 1st coordinate surface in a 1st step process and then having input of points on the drawing onto a 2nd coordinate surface according to a cursor in a 2nd step process. CONSTITUTION:A 1st coordinate surface XY is first chosen among those three coordinate surfaces XY, ZY and XZ by a stylus 3. Then the position of the styles 3 on a tablet 2a is displayed on a screen 29. The 2-dimensional coordinates and attribute of the data number are produced when a projected pattern is supplied with push of the stylus 3. The projected pattern is displayed on the screen 29. Then the surface ZY is selected. A 1st cursor is displayed at the input points of a 1st stage in the order of data inputs and an input enable area is secured at the periphery of the 1st cursor. Then the stylus 3 is moved and a 2nd cursor is shifted to a designated area of the 1st cursor. The final surface XZ is supplied with push of the stylus 3 for all data number points. Thus an input pattern is obtained to finish input of the 3-dimensional coordinates.

摘要： PURPOSE:To observe a stereoscopic image suitably at all times by impressing either a left eye picture signal or a right eye picture signal on the red signal input terminal of a color monitor, and the other on the green and the blue signal input terminal of the color monitor. CONSTITUTION:A filter 8 which passes through only red color light is used for a right eye, and a filter 9 which passes through light in green and blue colors and cuts the red color light is used for a left eye. The right eye picture signal 4r which is impressed on an input terminal 3R is displayed on a color monitor 1 as red, and can be seen only with the right eye. The left eye picture signal 4l which is impressed on a terminal 3L is displayed on the color monitor 1 as blue and partly as green, and almost of this signal can be seen with the left eye. Thus, a picture on the color monitor 1 can be seen stereoscopically. In an input terminal 2G, the input signal of the left picture signal 4l is level- adjusted by a variable resistance 6, so the green light at an optimum level can be emitted stereoscopically.

摘要： PURPOSE:To prevent deterioration in picture quality, by displaying alternately interlaced scanning picture information for a left eye and a right eye in a field unit on a monitor, after applying a double conversion on them respectively, meanwhile interrupting visual fields of right and left eyes of a viewer alternately making synchronize them with a field cycle, and selecting the start time and the completion time of a vertical deflection appropriately. CONSTITUTION:By supplying a left signal and a right signal to a circuit 3 by a left eye and a right eye television cameras 1L and 1R, both signals are time base-multiplexed, and also, are converted to ones of double speed, then being supplied to a monitor 4. And the start time and the completion time of the second field II are selected earlier than a case of A so as to constitute 0 fields at the first field I and the second field II. Similarly, a vertical return period is increased/decreased by every 0.5H. In this way, respective field can be constituted in the sequence of O, O, E, E, O, O, E... successively. Also, a picture based on a signal L and a signal R can be displayed on the monitor 4.
