Filed: 1992-05-12
Abstract: PURPOSE: To improve a picture quality by completely suppressing white noise occurring in a chrominance signal reproduction circuit so as to improve an S/N ratio. CONSTITUTION: A composite video signal is low-pass-converted through a low pass filter 1, is inputted to an automatic gain controller 2 and is inputted to an amplifier part 13. The output signal of the amplifier part 13 is inputted to an envelope detector 12 and only the peak value of a chrominance signal is detected. An envelope signal is supplied to an attenuator 15 as the attenuation control signal of the chrominance signal. The chrominance signal demodulated in a chrominance signal demodulator 3 is supplied to the attenuator 15 through a color killer circuit 6 and the level reduces by the attenuation control signal. A relationship with the attenuation quantity of the chrominance signal against the control voltage of the attenuator 15 has a prescribed critical value and an attenuation characteristic is maintained in an inverse proportion relation.  If the level of the chrominance signal becomes feeble and the envelope signal has the critical value when the chrominance signal has noise, white noise supplied to a band pass filter 10 through the attenuator 15 is largely suppressed at the same time.

Filed: 1982-07-08
Abstract: PURPOSE:To keep convergence in a suitable state, by distributing plural CRTs in a line and in the same direction to realize the miniaturization, and to reduce the effect of earth magnetism. CONSTITUTION:The CRT 16 and 18 and lens systems 19 and 21 of the side part are set closer to a screen 22 than a CRT17 and a lens system 20 at the center part. So that all optical axes are coincident with each other on the center axis of dichroic mirrors 23 and 24. In such a constitution, the effect of earth magnetism is never scattered even if the installing direction is changed since the CRT16, 17 and 18 are set in a line and in the same direction. This prevents the deterioration of convergence. At the same time, the miniaturization is attained owing to the in-line distribution of the same direction with the CRTs. In addition, all projection light beams are synthesized and projected on the screen 22 through the mirrors 23 and 24. Therefore, it is not needed to provide a troublesome correcting circuit for each CRT. As a result, the circuit constitution can be simplified.
