DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera-integrated recording device with a monitor, which is provided with an integrated monitor for easily confirming the photographing state of a subject.

[0002]

2. Description of the Related Art The appearance of a conventional general camera-integrated VTR is shown in FIG. In FIG. 12, reference numeral 101 denotes a camera unit, 102 denotes a VTR unit to which a tape cassette can be attached and detached,
Reference numeral 103 denotes a viewfinder for displaying a monochrome or color liquid crystal display for a monitor, 104 denotes an eyepiece, and 105 denotes a microphone.

Since the display screen size of the liquid crystal display panel in the viewfinder 103 is as small as about 1 inch square, an image magnified by an eyepiece is viewed through an eyepiece 104.

As described above, the small size of the liquid crystal display panel in the viewfinder 103 has an advantage that the cost of the liquid crystal display panel can be reduced. However, on the other hand, there are the following disadvantages.

[0005] That is, since the display screen of the liquid crystal display panel is viewed through the eyepiece 104, it can be seen only with one eye, making it difficult to see. The photographer positions his / her eyes away from the camera-integrated VTR main body. The viewfinder 103 cannot be used to monitor the shooting condition at the position. The viewfinder 103 is literally dedicated to obtaining the angle of view for shooting by the photographer. When shooting and recording the subject as a subject, another monitor having a large screen size is required, but this has a disadvantage that it cannot be easily realized.

Against this background, in recent years, there has been a demand for a camera-integrated VTR with a monitor that allows the user to easily check the photographing situation of a subject by moving away from the camera-integrated VTR main body without passing through an eyepiece. Is coming.

[0007]

However, instead of looking through the eyepiece as described above, an attempt was made to provide a monitor that allows the photographer to visually check the photographing situation of the subject while keeping his / her eyes away from the camera-integrated VTR body. In such a case, the screen size of the monitor is considerably larger than that of the viewfinder, but in the past, the ingenuity in arranging such a monitor was immature, so that the entire device became larger and easier to use. There was a problem that became worse.

For example, in a camera-integrated VTR with a monitor disclosed in Japanese Patent Publication No. 4-6154, a VTR unit and a monitor unit are integrated in a side-by-side state (a state where the VTR unit is fitted to the bottom surface of the monitor unit). In this manner, the camera unit is rotatably held on the long side surface of the monitor / VTR unit which is formed into an elongated rectangular parallelepiped shape.

However, in forming the monitor / VTR unit by integrating the VTR unit and the monitor unit, the VTR unit and the monitor unit are arranged side by side to form an elongated rectangular parallelepiped. The apparatus becomes large, and there is a limit in reducing the size of the entire apparatus.

The above publication does not consider the situation of face-to-face photography in which the photographer shoots and records the subject as a subject at all. The projected subject image is turned upside down and becomes an inverted image, and it is not practical at all for face-to-face shooting.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a monitor-integrated camera-equipped VTR capable of photographing and recording without any trouble, for example, when a photographer photographs and records himself as a subject. The purpose is to provide.

Is shown. This is the time of face-to-face shooting, but this state may be the storage posture when not in use.

Next, a specific state of use of the camera-integrated VTR with monitor in this embodiment will be described with reference to FIGS.

FIG. 8 shows a normal photographing state. In this state, the monitor / VTR 1
0 is rotated counterclockwise by a standard angle θ ₀ from the storage posture when not in use. The line of sight of the photographer is approximately 45 ° obliquely downward when the photographer is almost upright.

FIG. 9 shows a photographing state at a lower angle.
In this state, the monitor V
The TR unit 10 from the retracted position when not in use by the angle theta ₁ is rotated in the counterclockwise direction. Here, θ ₁ > θ ₀ , and the photographer leans forward slightly, and the line of sight is almost downward.

FIG. 10 shows a photographing state at an upper angle. In this state, the monitor / VTR unit 10 is stored with respect to the camera unit 13 when the monitor / VTR unit 10 is not in use.
9 is rotated clockwise by an angle θ _{2 in the} opposite direction to the state shown in FIG. The photographer's line of sight is obliquely upward.

As described above, by freely setting the camera angle and the monitor screen angle, the photographing situation of the subject projected on the liquid crystal display panel 17 having a relatively large liquid crystal screen size can be changed. Can take and record while visually checking the VTR 500 with the monitor and the camera-integrated VTR 500 itself.

FIG. 11 shows a state of face-to-face photographing.
In this state, the monitor / VTR unit 1 is moved from the storage position shown in FIGS.
By rotating 0 by 180 °, the photographing surface of the lens unit 28 and the liquid crystal display panel 17 are oriented in the same direction. At this time, the rotation of the camera unit 13 and the monitor / VTR unit 10 relative to each other by 180 ° activates the inversion detection switch 89 to drive the image upside-down inversion IC of the liquid crystal drive board 48 and the liquid crystal display panel 17. , The image can be projected upside down.

Then, the monitor-integrated camera-integrated VTR 500 in such a state is placed on a table 90 or the like, and the photographer separates from the monitor-integrated camera-integrated VTR 500 and remotely controls the remote control transmitter 91. The remote control includes zoom adjustment, recording start,
Pause (pause), stop, etc., an infrared remote control signal from the remote control transmitter 91 is received by the remote control signal receiving unit 20 of the camera-integrated VTR 500 with monitor, and a predetermined control operation is performed.

In this face-to-face photographing, the photographer takes his or herself as a subject and performs photographing and recording while displaying the image as an upside-down image on the liquid crystal display panel 17. Here, since the display screen size of the liquid crystal display panel 17 is relatively large, the photographer can visually confirm the photographing state of the subject satisfactorily if the photographer is slightly away.

The camera-integrated VTR 500 with monitor
Is set on a tripod, and the rotating mechanism 14 is configured to be driven by a motor, and the motor is driven by remote control by a remote control transmitter 91 so that the camera unit 13 and the monitor / VTR unit 10 May be remotely controlled.

Further, in the above-described embodiment, a description will be given of an example in which the upside-down switching of the image projected on the liquid crystal display panel 17 is automatically performed by the relative rotation of the camera section 13 and the monitor / VTR section 180 by 180 °. However, the switching may be performed by a manual switch or a remote control so that the user can arbitrarily invert the image up and down. It is apparent that the present invention is not limited to the above-described embodiment by providing an automatic mode, a manual mode, or the like.
