Abstract: PURPOSE:To change display colors at a high speed and at the same time to reduce the CPU load by adding the prescribed value to the input data to supply them to a color conversion table and changing the prescribed value to be added. CONSTITUTION:Partial picture data is read out of a RAM 6 at a position where the display of screen is desired according to a command of a CPU and supplied to a secondary color conversion table 7. Then the partial picture data is taken out by a switch circuit 3S in place of the data given from a video RAM 1 and supplied to a color conversion table 4. The pointer value given from a pointer generating part 9 is supplied to an adder circuit 8 to which the output of the table 7 is supplied. Then the output of the table 7 is added to the pointer value and this addition output is supplied to the table 4 at a partial picture part on a screen. The pointer value is set by the CPU and can also be changed optionally.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device, in which a displayed image can be clearly recognized even under a bright external light 5, and the external light is used efficiently for suppressing the energy consumption. SOLUTION: A liquid crystal panel part 41 is constituted, by mounting a Fresnel lens 43 on the back face of the liquid crystal panel 22 of a notebook- type personal computer. A backlight and external light reflecting part 44, having a backlight and external light reflecting mechanism 46 is pivoted to the liquid crystal panel part 41 by the hinge 45 for the backlight and external light reflecting mechanism, so that the reflecting part 44 is freely rotatable. A light diffusing plate 48 is pivoted to the end of the reflecting part 44 by the hinge 47 for the light diffusing plate, so that the plate 48 can freely rotates. When bright external light 5 is present, the backlight and external light reflecting part 44 is rotated, to open outward so that the external light 5 is diffused by the diffusing plate 48 and reflected on the reflecting mechanism 46 to spread over the whole surface of the liquid crystal panel 22. When external light 5 is dark, the reflecting part 44 is closed to be in contact with the liquid crystal panel 41, the light diffusing plate 48 is folded to the outside and the light source of the reflecting mechanism 46 is turned on for use.

Abstract: PURPOSE: To provide a head mounted display device, by which the display position of an image which a user views can easily vertically be moved and the deterioration of the reflection efficiency of a half mirror is hard to occurr. CONSTITUTION: The image displayed on a liquid crystal display 1a or 1b from a small VTR part 13 through a circuit box 12 can be viewed by the user through a mirror 2a, a lens 3a and the half mirror 4 or a mirror 2b, a lens 3b and the half mirror 4. The half mirror 4 is rotated and the display position of the image which the user views can vertically be moved by providing a rotation mechanism part supporting the half mirror 4 in a rotation possible state. The surface of a reflection layer can be protected and the state of the surface is prevented from changing so as to prevent the deterioration of reflection efficiency by sandwiching the reflection layer of the half mirror 4 by two transparent base plates.

Abstract: PURPOSE:To provide a picture display device capable of controlling the brightness of pictures without damaging the quality of displayed pictures. CONSTITUTION:A light reduction filter 4 composed of a liquid crystal shutter or the like is arranged on a transmission light control type display 2 composed of an LCD or the like for which input signals and a light emission amount are provided with nonlinear characteristics. Thus, the brightness of the entire display pictures can be controlled from the extremely low level of luminance to a bright level. As a result, the faithful brightness of the display pictures can be reproduced and the paint-out of black and white does not occur.

Abstract: PURPOSE:To provide the optical device which effectively averts the possibility of the content of a virtual image being viewed by a third person exclusive of a person wearing this device and enables the person wearing this device to view the distinct virtual image without being conscious of the presence of a spectral means existing in the visual field region of the virtual image. CONSTITUTION:The video R projected on a polarized light control type display 18 is made incident via optical systems 19 and 21 on the polarization type spectral means 22 and are totally reflected to the wearing person side in the polarization type spectral means 22. The quantity of external light L13 entering from a peripheral visual field region ARO is attenuated by a light attenuating means 24 so as to decrease the difference in the quantity of the external light L12 entering from the virtual visual field region ARI.

Abstract: PROBLEM TO BE SOLVED: To provide such a virtual image that a distance from a user is changed by a video.
SOLUTION: The virtual image is provided with a shape suitable to the video. When a video is broadcasted as a movie and a drama having an aspect ratio of 16:9 by a high-definition television broadcast, a large virtual image is formed in a position far away from a user, for example, by about 15m in the display device 4. When a video is broadcasted as a television signal having an aspect ratio of 4:3 by an NTSC system, a middle-sized virtual image is formed in a position comparatively close to the user, for example, by about 3m in the display device 4. Whether the video is broadcasted by the high-definition television broadcast or the NTSC system is determined, for example, based on the synchronization signal of the television signal.
