    Abstract: A picture signal recording system comprises a high-definition broadcasting station 1, an artificial satellite 2, a television receiver 3 and a video signal recording apparatus 5. A pilot signal P is superimposed on a luminance signal Y at the broadcasting station 1. This pilot signal P does not give any adverse influence to an image reproduced on a TV monitor and is detectable from the luminance signal Y. A frequency of this pilot signal is selected to be smaller than the frequency of the luminance signal Y, a superimposing timing thereof is set to a head position of the luminance signal Y, and an amplitude thereof is varied with respect to a grey level as a variation center. The pilot signal P superimposed on the luminance signal Y is detected by a pilot signal detecting circuit 53 within a video signal recording apparatus 5. The picture signal is recorded on a video tape 11 and rerecording prohibit information is recorded in a reserved area by a picture signal recording process circuit 51. When the video tape 11 on which this rerecording prohibit information has been recorded is reproduced, the reproduced picture signal is prohibited to be rerecorded.

    Abstract: Provided is a projection type liquid crystal display apparatus, which can improve black-level display and thus can display a higher-contrast image as compared to the related art. An optical compensator is located on the light exit side with respect to the liquid crystal display device so as to compensate for the optical phase difference caused by liquid crystal molecules in a light-entry-side region of the liquid crystal layer. As the optical compensator is located on the light exit side with respect to the liquid crystal display device, birefringence, caused by the liquid crystal molecules present in the light-entry-side region, is compensated for without being influenced by a microlenses provided in the liquid crystal plane. Consequently, the apparatus can improve the black-level display and thus can display a higher-contrast image as compared to the related art. Further, a phase difference caused by the birefringence of the nematic liquid crystal molecule is compensated for by using a substance having properties optically opposite to the positive crystal, namely, a substance having birefringence equivalent to birefringence of a negative crystal.

    Abstract: In active driving of liquid crystal panels (R, G, and B) corresponding to R, G, and B color by X shift registers (R, G, and B) and Y shift registers (R, G, and B), alternating-current driving is performed such that signals to be written to the R color and B color liquid crystal panels are opposite in polarity to a signal to be written to the G color liquid crystal panel and also Vcom voltage of each of the liquid crystal panels is adjusted to thereby reduce flicker. The Vcom voltage supplied to the B color liquid crystal panel, for example, is finely adjusted to reduce flicker of a synthetic image of the liquid crystal panels.

    Abstract: To effectively make a mesh of out lines between pixels by a pixel diffusion and at the same time to facilitate a focusing of an image by the observer, an optical filter for diffusing each pixel of a display device into a plurality of parts by utilizing diffraction or refraction is interposed between the display device having an image pattern in a mosaic form and an observer. The optical filter surface performs the pixel diffusion so that a sight angle, of a gap which does not pass light between the neighboring pixel after the pixel diffusion, as viewed from the observer on the focal plane on which the image displayed by the display device is observed by the predetermined observer is substantially a recognizable limit view angle of the observer.

    Abstract: Apparatus is provided for recording and reproducing video and audio signals on a record medium, wherein the audio signal may be of at least two different types subjected to respectively different types of audio processing. A recording section produces frequency modulated audio signal components and selectively adjusts the level of at least one FM audio signal component during the video blanking intervals as a function of the type of audio signal being modulated. Then, the FM audio signal components and the video signal are combined and recorded. A reproducing section separates the reproduced FM audio signal components from the reproduced video signal and detects the level of at least one separated FM audio signal component during blanking intervals. The FM audio signal components are demodulated and processed pursuant to a selected type of audio processing dependent upon the detected level of the FM audio signal component.
