摘要： A recorder has a recording medium for information recording, a light source, an optical system, a slider, and an optical waveguide. To the optical system, light from the light source enters, and the slider moves relative to the recording medium while not in contact therewith. The optical waveguide is arranged at position facing the recording medium in the slider so that light entering from the optical system is irradiated on the recording medium. Where the mode field diameter of the optical waveguide on the light output side is d and the mode field diameter thereof on the light input side is D, the mode field diameter is converted by smoothly changing the diameter of the optical waveguide to satisfy D>d.

摘要： A display apparatus which has a mirror with a free curved reflective surface of which curvature fluctuates with inflection points, a liquid crystal display (LCD), a back light and a polarizer. Light of an image which was modulated by the LCD is reflected by the free curved reflective surface and passes through the polarizer. Then, the light is directed to an optical pupil. Since the curvature of the free curved reflective surface fluctuates with inflection points, curvature of field and distortion can be corrected properly, and an image of high quality can be formed.

摘要： A resonant optical device has a rod-like resonator made of a fiber-reinforced resin for resonant vibration. A reflecting mirror is supported on the leading edge of the resonator. A drive unit oscillates the resonator in a circumferential direction. The base edge of the resonator is anchored to a stationary platform. The reflecting mirror is oscillated by a torsional oscillation produced by oscillation from the drive unit so as to scan light incident on the reflecting mirror. The resonator satisfies the expression G/.rho..gtoreq.12.times.10.sup.6 Pa.multidot.kg.sup.-1 .multidot.m.sup.3, where the horizontal elastic modulus of the resonator is designated G, and the density is designated .rho.. The resonator also satisfies the expression .tau./G.gtoreq.0.01, where the torsional stress tolerance is designated .tau.. In one embodiment, the fiber-reinforced resin is a carbon fiber-reinforced resin.

摘要： A video reproducing apparatus which prevents a degradation in the picture quality by utilizing difference codes which have been added as additional information in coding process based DCT coding. Each of the taken-in codes has its header analyzed by a header analyzer 11, is decoded in a decoder 12, inverse-quantized in an inverse quantizer 13, and inverse-DCTed in an IDCT stage 14, thus yielding expanded pictures. If additional information has been added, the information is read by an additional information reader 21, the read difference codes contained in the extra information are expanded by an additional information decoder 22. The expanded difference code and video data from the IDCT stage 14 are synthesized by a video synthesizer 23 to yield high definition video data.

摘要： A motion picture reproducing system by bidirectional communication, in which characters and graphics are separately encoded to reproduce high quality images. A video server transmits the motion picture codes of the desired video to a terminal in response to a request of the terminal. At that time, by checking a terminal registration information file, it is discriminated whether or not a bit map of the characters and the graphics stored in the user region of the motion picture codes is registered in the terminal. When the bit map is not registered in the terminal, the bit map data are transmitted to the terminal by a bit map encoder. The terminal reads out bit map codes stored in the user region of the motion picture codes and reproduces the bit map date in a bit map decoder. An optimum encoding can be carried out and a code size can be further compressed.

摘要： In video/audio compression, a video signal is separated into luminance and a color difference. The color difference is partially subsampled. An interframe difference is compression-coded by an encoding unit. At that time, particular subsampling information corresponding to a designated reproducing rate is extracted from subsampling information. The particular subsampling information is inserted into compressed video data. On the other hand, in video/audio reproduction, the color difference of the video, which has partially been subsampled, are interpolated by a decoding unit with reference to the subsampling information inserted into the compressed video data.
