Abstract: A selection unit selects ‘0’ for the first through the (N?1)th frames, and selects a predicted image for the subsequent frames. Thus, an intra-frame coding process is performed on the first through the (N?1)th frames, and an adaptive coding process is performed on the subsequent frames. An information amount reduction unit reduces the amount of information about data in the first through the (N?1)th frames. An information amount adjustment unit stepwise increases the amount of information reduced by the information amount reduction unit.

Abstract: A cathode ray tube according to the present invention include a cold cathode electron gun, the cold cathode electron gun including a cold cathode array for emitting electrons through field emission, a gate electrode for controlling the field emission, a first selective electrode provided around the cold cathode array and the gate electrode, and a second selective electrode opposing the first selective electrode, and the second selective electrode is adapted to have a lower potential than the gate electrode and the first selective electrode. In accordance with this configuration, the divergence of electron beams emitted from any positions in the cold cathode array can be converged uniformly upon removing electron beams emitted at a great emission angle. This allows the electron beams thereafter to be made narrower by an electrostatic lens. As a result, the present invention can provide a cathode ray tube capable of forming a high-resolution image.

Abstract: A CRT device includes a cold cathode electron gun realizing high resolution in all current areas. A field emitter type cathode having a field emitter array and a gate electrode, a first grid electrode, and a second grid electrode constituting the electron gun are arranged in this order toward a phosphor screen. The potential Vgate of the gate electrode is higher as the beam current is larger. The potential Vg1 of the first grid electrode takes a fixed value smaller than the potential Vgate. As the beam current increases, electrons passing through the gate electrode are accelerated more and converged to a lesser degree, whereas the lens strength of the cathode lens formed by the gate electrode, the first grid electrode, and the second grid electrode is enhanced more. Therefore, the beam diameter at the main lens can be made uniform regardless of the amount of beam current.

Abstract: The object of the invention is to provide an optical pick-up apparatus and a semiconductor laser apparatus which can suppress reduction of optical utilization efficiency for the laser light emitted from the semiconductor laser element. When a laser light which is emitted from a laser element for DVD and whose polarization direction is perpendicular to a direction of a groove of the polarization grating is incident on the polarization grating, the polarization grating does not diffract the laser light and transmits the laser light as zero-order diffraction light. Consequently, all of the laser light A emitted from the laser element for DVD can be used for reading information signal of DVD and detecting FES and TES. This enables reduction of optical utilization efficiency arising by diffracting action of a grating used for detecting TES of CD in a conventional optical pick-up apparatus to be suppressed.
