DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a wide screen having a screen aspect ratio of 9:16 using a wide liquid crystal display.
The present invention relates to a liquid crystal integrated video camera capable of switching between a standard screen of 3: 4 and photographing.

2. Description of the Related Art In recent years, there has been an
Wide broadcast of S. In addition to the favorable background that the second generation clear vision (EDTV2) may start in the middle of 1995 in terrestrial broadcasting, the fact that it is time to replace large-screen TVs is also a follow-up. The wide TV market is booming. Display A
If you think that it is the core of the V system, a wide-screen TV that gives you an overwhelming sense of realism is the cornerstone of home entertainment appropriate for the new era. In order to provide video software utilizing this wide-screen television, a camera-integrated VTR equipped with a wide function has been proposed. On the other hand, a camera-integrated VTR
A liquid crystal monitor (electronic viewfinder) of about 3 to 4 types, which can be viewed on the spot from the mounting of a color viewfinder of 1 type or less, is being mounted.

To explain the wide function, for example, an EIS / CCD of 580,000 pixels has a camera shake correction area around a photographic screen portion equivalent to 1/4 inch.
Specifically, the conventional effective pixel part is 1/3 inch,
All effective pixels in the area are horizontal 838 × vertical 670. At the time of camera shake correction, from 1/3 inch, 670 x horizontal
One quarter inch of 485 vertical pixels was cut out and used. The vertical 485 pixels are determined from the effective scanning line. If it is spread horizontally as it is, 16: 9 if 838 pixels
Wide TV size is obtained. 4: 3 as before
A wide screen can be obtained without cutting out from the video.
This is a high-quality wide screen full-wide mode, in which the number of effective pixels is about 410,000. Recording on a video tape is performed on a squeeze screen in which the left and right sides are compressed. However, even if the image is enlarged and reproduced at 16: 9 on a wide-screen television, the resolution is not deteriorated both horizontally and vertically. Compared to the conventional wide mode, the resolution is increased by about 25% in both the horizontal and vertical directions.
It is important to make software that makes full use of the performance of this wide mode.

A conventional liquid crystal integrated video camera will be described below. FIG. 3 shows a configuration diagram of a conventional liquid crystal integrated video camera equipped with two electronic viewfinders. In FIG. 3A, reference numeral 1 denotes a color liquid crystal monitor (color electronic viewfinder). Reference numeral 2 denotes a magnetic recording / reproducing device. Reference numeral 3 denotes an electronic camera unit. Reference numeral 4 denotes a cathode ray tube electronic view finder using a B / W cathode ray tube. 5 is a first switch. Reference numeral 6 denotes an operation panel for adjusting one color liquid crystal monitor.

The operation of the liquid crystal integrated video camera configured as described above will be described below. Using the color liquid crystal monitor 1 to check the subject when recording the image signal from the electronic camera unit 3 to the magnetic recording and reproducing device 2 and to check the image recorded on the magnetic recording and reproducing device 2 It is shown. In this case, the cathode ray tube electronic viewfinder 4 is stored unused. In this state, the first switch 5 is turned on, for example, and the cathode ray tube electronic viewfinder 4 is turned off in a state where the color liquid crystal monitor 1 operates. In the state described above, for example, an external signal from, for example, a TV tuner can be viewed on the color liquid crystal monitor 1.

FIG. 3B shows a case where the photographing conditions are poor, for example, in a bright outdoor place or when the movement of the subject is fast and the follow-up property is required, the color liquid crystal monitor 1 is housed and the first switch 5 is turned off. The video signal from the electronic camera section 3 is recorded in the magnetic recording / reproducing apparatus 2 using the cathode ray tube electronic viewfinder 4.

[0007]

However, the conventional configuration described above has a drawback that it is not possible to make full use of video software at a shooting angle taking advantage of the performance of the wide function. For this reason, wide color LCD monitors have been required. The configuration using a wide-screen color liquid crystal monitor has a disadvantage that the configuration becomes large in consideration of the arrangement of the six operation panels described above. 4 on a wide color LCD monitor:
There is a problem that when the image of the third screen is projected, a sense of incongruity appears.

The present invention solves the above-mentioned conventional problems, and provides an image which can be reliably shot at a desired angle by displaying a screen corresponding to each aspect ratio on a wide liquid crystal display without a sense of incongruity. Is what you do.

[0009]

SUMMARY OF THE INVENTION In order to achieve this object, a liquid crystal integrated movie of the present invention is provided with a wide liquid crystal display of, for example, about 4 to 5 inches and providing a screen corresponding to each aspect ratio. In the case of a 16: 9 wide screen, the screen is projected to fill the wide liquid crystal display. On the other hand, when the 4: 3 standard screen is used, an ineffective portion may be generated at the right end of the screen and may be annoying, by providing an operation panel that covers this portion.

[0010]

With this structure, the operation panel can be moved on the liquid crystal display so that both the 16: 9 image and the 4: 3 image can be seen without any discomfort. In addition, it is possible to effectively arrange the operation panel arrangement, which has become difficult at the time of wide support.

[0011]

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, the same components as those of the prior art are denoted by the same reference numerals, and description thereof will be omitted. Reference numeral 6 denotes an operation panel. Reference numeral 7 denotes a wide LCD (color liquid crystal display). 8 is an outer frame.

The liquid crystal integrated video camera configured as described above will be described with reference to the drawings.

An operation panel 6 is arranged on the left side, right side, or both sides of an outer frame 8 (exterior part) surrounding the wide LCD 7. Here, the description will be made with the one arranged at the right end.
The above-mentioned operation panel 6 is housed in the outer frame 8 at the time of the 16: 9 wide screen as shown in FIG. In this case, only when adjustment is performed, the operation panel can be pulled out on the screen and stored after performing adjustment.

Next, at the time of the 4: 3 standard screen, as shown in FIG. 2, the operation panel 6 is pulled out from the outer frame 8 and is fixed to an ineffective portion of the wide LCD 7. Operation panel 6
At the top, function keys for adjustments such as monitor related are arranged,
Use according to the purpose.

[0015]

As described above, according to the present invention, a space for arranging the operation panel is secured, and an undisplayed portion (usually black spot) generated when a standard screen is projected on a wide LCD is unsightly. This has the effect of preventing things that would otherwise be covered by the operation panel, thereby realizing an excellent liquid crystal integrated video camera.
