摘要： PURPOSE:To miniaturize the display device and to improve resolution by constituting the display device of a color image display device for one horizontal scanning line provided with three primary colors emitting means arranged in parallel with a horizontal scanning line section and an optical system means for deflecting image light for one scanning line projected from the display device in the vertical direction. CONSTITUTION:The display device is constituted of a cathode ray tube (CRT) 1 provided with three primary colors emitting means 14B, 14R, 14G arranged in parallel with the horizontal scanning line section and three electron gans 4B, 4R, 4G making pairs with the means 14B, 14R, 14G, a horizontally deflecting coil 2, the optical system 16 for deflecting image light for one horizontal scanning line projected from the CRT 1 in the vertical direction synchronously with a vertically synchronizing signal included in an image signal, and a driving device 17 for driving the optical system 16. Cathode rays are projected from the three electron gans 4B, 4R, 4G and deflected in the horizontal direction by the coil selectively emit the corresponding light emitting means 14B, 14R, 14G. In addition, image light raidated from the CRT 1 is deflected in the vertical direction by the optical system 6 to constitue an image. Thus, the display device can be miniaturized and high resolution can be attained.

摘要： PURPOSE:To make the picture quality of a video good by arranging apparatus to illuminate a person, who intends to speak, on both sides of a screen. CONSTITUTION:At the time of photographing a speaker by means of a television camera, a vertical illuminance of about 1000Ix is obtained at the position of the face of the speaker by a lighting apparatus 5, and at the same time, a direct glare from a luminaire 5 is suppressed by a light shielding plate 5c, while light is cast effectively and adequately in the direction of the face. Accordingly, the face of the person can be expressed normally without producing a shadow on his face or changing the expression of the face.

摘要： PROBLEM TO BE SOLVED: To reduce an effect of a light after color separation onto a spectrum distribution due to a very slight dispersion in a spectral transmission factor characteristic of color filters by effectively using the energy of a light from a light source in the picture display device that uses the light separated into four colors or over by the color filters to reproduce a color picture. SOLUTION: In the picture display device that has a light source and 4 kinds of color filters or over, allows the color filters of 4 kinds of over to separate the light emitted from the light source into four colors or over and uses the color-separated light to reproduce a color picture, the spectral transmission factor characteristic of the color filters is selected so that each cut-off wavelength of the color filters of 4 kinds or over is present in a wavelength band that is smaller than a value being a product between an integer and a mean value in a wavelength band from 380 nm to 780 nm of a spectral distribution obtained by multiplying a color matching function with a spectral radiation characteristic of the light emitted from the light source.
