Abstract: The present invention is intended to improve an image quality in an image display apparatus, which requires to individually transmit signals to portions corresponding to a plurality of pixels or lines, such as a liquid crystal display, a plasma display and the like. In signal transmitting sections 4, 5 for transmitting signals to an image display section to which independent signals are applied for each pixel or line, a plurality of transmitting lines arranged parallel to each other at regular intervals are brought for each plurality of transmitting blocks. A transmitting line, servicing as a dummy between transmitting lines which are located in different transmitting blocks and adjacent to each other, is disposed in any one of transmitting blocks including the adjacent transmitting lines. A transmitting line nearest to the dummy transmitting line in the other transmitting block of the transmitting blocks including the adjacent transmitting lines is electrically connected to the dummy transmitting line outside of the signal transmitting sections 4, 5.

Abstract: PROBLEM TO BE SOLVED: To reduce the burning of a plasma display panel.
SOLUTION: An optical write type liquid crystal panel is combined with a front face of the plasma display panel to constitute a display panel part. When a moving image is displayed, the moving image is displayed on the plasma display panel and an optical transmittance of the optical write type liquid crystal panel is set to a fixed value or higher, whereby the moving image can be observed through the optical write type liquid crystal panel 2. When a still image is displayed, an image is written and fixed to the optical write type liquid crystal panel 2 by the still image displayed on the plasma display panel, and then the plasma display panel is switched to overall white display. Thus image light modulated by the optical write type liquid crystal panel 2 is displayed as a still image with white light of overall white display as a back light.

Abstract: PURPOSE: To reduce disturbance in an image seen through a shutter eyeglass to the utmost by noise immunity performance as to space transmission of a switching synchronizing signal so as to widen a service area even when malfunction due to signal transmission takes place. CONSTITUTION: A switching synchronizing signal from the equipment body 1 is given to an FM modulator 2, in which the signal is frequency-modulated and its FM signal is outputted from the FM modulator 2 and given to an electro/optic converter 3 and intensity modulation is applied to an infrared ray according to the FM signal. The infrared ray signal is emitted in the air. An optical/ electric converter 4 provided in addition to a shutter eyeglass 7 receives the infrared ray signal emitted in the air and converts the signal into an electric signal. An FM demodulator 5 demodulates the received signal to reproduce a switching synchronizing signal. A shutter drive circuit 6 is operated according to the reproduced switching synchronizing signal to alternately apply on/off drive to a left/right shutter of the shutter eyeglass 7.

Abstract: PROBLEM TO BE SOLVED: To provide a signal handled by a device with conformity to a prescribed specification for expressing a color with the color gamut larger than a prescribed specification. SOLUTION: In a primary color conversion unit 62, a first color at a primary color point with the color gamut larger than an original color point of BT.709 is converted to a second color signal based on a primary color of BT.709. In a photoelectric conversion unit 63, the second color signal is converted to a third color signal according to characteristics of photoelectric conversion defined in a numerical range larger than a numerical range of 0 to 1.0 that brightness signal based on BT.709 and a color signal based on color-difference signal can take. In a color signal conversion unit 64, the third signal is converted to a brightness signal and a color difference signal. In an integrated compensation unit 64A, the color difference signal is compensated to a color difference signal of -0.57 to 0.56 including -0.5 to 0.5 of BT.709 which is expressed by allotting it to an integer value of 1 to 254 including 16 to 240 of BT.709. This invention can be applied to a video camera, for an example. COPYRIGHT: (C)2006,JPO&NCIPI
