Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television apparatus having a built-in video reproducing apparatus for reproducing a video signal recording medium, and more particularly to an optical disk apparatus suitable for reproducing and displaying a video signal recorded on an optical disk. The present invention relates to a built-in television device.

[0002]

2. Description of the Related Art A so-called video tape recorder (hereinafter referred to as VT) using a magnetic tape as a recording medium for video signals.
A television device having a built-in R) and capable of easily reproducing and displaying an image has been commercialized. On the other hand, in recent years, instead of a magnetic tape, a compact disk read only memory (CD-ROM) or a magneto-optical disk (Magneto Optical Disk: MO) is used.
An optical disk device has been developed in which a digital video signal is recorded on an optical disk such as the above, the digital video signal is read by an optical pickup, and the video signal is obtained by digital signal processing.

As an optical disc, a so-called photo CD for recording a natural image as a still image, reading it out and displaying it as a still image on a television device,
There is one called a video CD in which a video signal of a moving image (hereinafter referred to as a moving image signal) is recorded and read out to display a moving image on a television device. Especially video C
In D, the moving image signal is recorded as a data-compressed digital signal.

[0004]

In the conventional VTR, the magnetic tape is used as the recording medium for the video signal.
No particular consideration was given to dust. On the other hand, when an optical disc is used, since an optical pickup is used, it is necessary to give sufficient consideration to dust. Further, since a digital signal processing circuit is used, it is necessary to consider noise.

Further, when a photo CD is reproduced to display a still image, line flicker is conspicuous, and when a moving image signal compressed by the MPEG standard is read from a video CD and a moving image is displayed, a block is displayed. There was a problem that noise and mosquito noise were noticeable and the image quality was significantly deteriorated. These noises are obtained by digitalizing the moving image signal and compressing the data.When displaying the moving image, this moving image signal is digitally processed and, like the received video signal, further processed by the video signal processing circuit. The mosquito noise is generated in the contour portion of the image, and the block noise is generated in the other flat portion of the luminance.

That is, when the moving image signal is digitized and data is compressed, the contour portion of the image is inevitably emphasized. If this is emphasized by the video signal processing circuit during reproduction, the image is overemphasized. The outline is displayed as glaring. This is mosquito noise.

In the MPEG standard, the video signal is
Data compression processing is performed for each area obtained by dividing the screen into a plurality of areas.
Although this division is a block, if a block is used as a unit of data compression in this way, when data expansion processing is performed for each block to obtain the original data amount, the amount of data slightly different from the original amount between adjacent blocks. There is a difference, which causes a slight image on the grid on the display screen to frame each block. This is block noise.

[0008] Block noise is not particularly noticeable because mosquito rises appear prominently in the contour portion of an image.
It appears relatively conspicuously in the part where the brightness is almost uniform.

It is a first object of the present invention to provide a television device with a built-in optical disk device, which can solve the problem of dust and noise.

It is a second object of the present invention to provide a television device with a built-in optical disk device, which can perform display suitable for the type of video image based on the information on the video signal from the optical disk device.

[0011]

In order to achieve the above first object, the present invention provides an optical disc device which is arranged away from a high voltage generating portion of a cathode ray tube and a tuner circuit vulnerable to noise.

Further, in order to achieve the first object,
The present invention shields an optical disk device.

In order to achieve the above-mentioned second object, the present invention reads a video signal and information related thereto from an optical disk device and optimally controls the video display of this video signal.

[0014]

Since the high-voltage generating portion attracts dust, the optical disc device is arranged away from this, so that the dust does not reach the optical disc device.

When a video CD or the like in which a video signal is recorded as a digital signal is read by an optical disk device, noise is likely to occur when the read digital video signal is digitally processed. The tuner circuit is
Since the weak received signal is handled, it is easily affected by noise.However, since the optical disk device is placed away from the tuner circuit, the effect of noise on the tuner circuit is reduced even if the optical disk device is built into the television device. It

Further, since the optical disk device is shielded, the optical disk device is protected from dust, and even if it is arranged near the high voltage generating portion, there is no problem in each case. By making the shield conductive, noise generated in the digital processing unit of the optical disc device does not go out of the optical disc device, and therefore the optical disc device can be arranged near the tuner circuit. Therefore, by doing so, the restriction on the arrangement of the optical disk device in the television device can be greatly relaxed.

Further, in addition to the video signal, information relating to the video signal is also supplied to the display portion, so that the video signal can be optimally displayed. As a result, it is possible to set display conditions such that flicker when displaying a still image, block noise and mosquito noise when displaying a moving image are not noticeable, and an image from an optical disc can be displayed with good quality. .

In any case, dust that is attracted to the high voltage generator 4 and the anode electrode 5 is blocked by the shield member 7 and cannot enter the optical disk device 3. Therefore, even if the optical disk device 3 is arranged near the high voltage generating portion 4 and the anode electrode 5, there is no problem. Further, if the shield member 7 is made of a conductive material, noise generated in the optical disk device 3 will not be emitted to the outside by the shield member 7, and therefore,

The image display on the display unit 2 can be optimally controlled.

For example, when information 9 indicating whether the video signal 8 is a still image signal or a moving image signal is given to the television receiving / display unit 2, line flicker may occur when the image read from the optical disk is a still image. To make it stand out, darken the screen to make it inconspicuous.In the case of video, darken the screen and weaken the edge enhancement processing to make block noise and mosquito noise inconspicuous, and receive it in the tuner circuit.

In FIGS. 9 and 10, the input luminance signal S0 is sequentially delayed by the delay circuits 20a and 20b by a small time τ, and the luminance signal S2 delayed by 2τ and the input luminance signal S0 are added by the adding circuit 21. Is added. Then, in the subtraction circuit 22, τ output from the delay circuit 20a
The output signal SA of the adder circuit 21 is subtracted from the luminance signal S1 delayed only by this, the contour portion of the delayed luminance signal S1 is secondarily differentiated, and the contour emphasizing signal SB of the inverted waveform is obtained.

The contour emphasis signal SB is supplied to the variable gain amplifier circuit 23. The gain of the variable gain amplifier circuit 23 is controlled by a gain control signal supplied from the microcomputer 19 of FIG. 8 through the input terminal 25. This gain is higher in the optical disk 10 than in the case where the optical disk 10 is not a video CD. Set small for video CDs. Therefore, the contour emphasis signal SB has a smaller amplitude when the optical disc 10 is a video CD than when the optical disc 10 is not a video CD.

When a control signal is supplied from 9 to the input terminal 39, the gains of the variable gain amplifier circuits 31 and 32 are controlled as follows.

That is, in the variable gain amplifier circuit 31, the gain is set small during the positive polarity period of the differential signal S3, and the gain is set large during the negative polarity period of the differential signal S3. Here, the positive polarity period and the negative polarity period of the differential signal S3 are in timing with the positive polarity portion and the negative polarity portion of the contour emphasis signal SA, respectively, so that the contour output from the variable gain amplifier circuit 31. The amplitude of the enhancement signal SC is compressed in the positive electrode portion and expanded in the negative electrode portion.
Further, in the variable gain amplifier circuit 31, the gain is set large during the positive polarity period of the differential signal S3, and the gain is set small during the negative polarity period of the differential signal S3. Here, during the positive polarity period and the negative polarity period of the differential signal S3, the negative polarity portion and the positive polarity portion of the contour emphasizing signal SA are in timing, respectively. In the signal SD, the amplitude of the negative electrode portion is expanded and the amplitude of the positive electrode portion is compressed.

These contour emphasizing signals SC and SD are added by the adding circuit 33 and supplied to the adding circuit 35 through the variable gain amplifying circuit 34 whose gain is adjusted by the control signal from the input terminal 40, and the delay circuit 27 of the delay circuit 27. It is added to the contour portion of the output luminance signal S1.

Here, as described above, the gains of the variable gain amplifier circuits 31 and 32 are set to be equal and constant except for the reproduction of the video CD, so that the luminance signal obtained from the adder circuit 35 is As shown in FIG. 10c, the contour portion is emphasized. However, in the case of the reproduction luminance signal from the video CD, the variable gain amplifier circuits 31, 3
Due to the change in the gain of 2, the contour emphasis signals SC and SD output from the respective ones have their positive portions compressed, so the luminance signal SF obtained from the adder circuit 35 to the output terminal 36.
Is hardly emphasized immediately after the rising contour and immediately before the falling contour. Therefore, the emphasizing effect is lower than that of the edge emphasizing in the case other than the reproduction of the video CD, and the mosquito noise becomes inconspicuous.
