DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to multi-binoculars (and telescopes), and can obtain various functions by being combined with a video camera.

[0002]

2. Description of the Related Art Binoculars (telescopes) are used to observe a remote object in an enlarged manner. However, the conventional device has only a function of viewing the subject, and when separately viewing the reference material, the user must temporarily remove his / her eyes from the eyepiece to view the reference material.

[0003] In addition, in the case of taking an image while observing a remote object with binoculars (telescope), it is necessary to prepare a video camera separately. For this reason, the imaging timing may be lost or the subject may be lost.

[0004]

As described above, the functions of the conventional binoculars (telescopes) are limited to the function of simply enlarging the subject, and thus have reached the limit in expanding the application. .

Accordingly, an object of the present invention is to provide a multi-binocular having abundant functions by integrating a binocular (telescope) and a video camera and devising the arrangement of a viewfinder of the video camera. is there.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides first and second lens barrels whose insides can be viewed through left and right eyepieces, and the first and second lens barrels. And first and second liquid crystal display panels of first and second video cameras respectively provided on the liquid crystal display panel, and means for displaying image data in a memory on the liquid crystal display panel.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. 1
1R and 11L are lens barrels. The lens barrel 11R is provided on its optical axis with an objective lens 1R, a liquid crystal display element 2R, a half mirror 3R, and an eyepiece 4R. Lens barrel 11L
Has an objective lens 1L and a liquid crystal display element 2 on its optical axis.
L, a half mirror 3L, and an eyepiece 4L are provided.

The light transmitted by the half mirror 3R is guided to the eyepiece 4R, and the light reflected by the half mirror 3R is guided to the video camera 12R. The light transmitted by the half mirror 3L is guided to the eyepiece 4L, and the light reflected by the half mirror 3L is guided to the video camera 12L. The signals captured by the video cameras 12R and 12L are guided to video signal processing circuits 13R and 13L, respectively. Output signals of the video signal processing circuits 13R and 13L are stored in, for example, the memory 21. Alternatively, it may be stored in the external memory 22 composed of a large-capacity semiconductor memory. Further, the signal may be transmitted to the outside through the signal input / output unit 23.

In the above-described apparatus, a stereoscopic video image can be obtained based on the radiating angles of the lens barrels 11R and 11L.
The left and right images are kept synchronized by the synchronization processing of the system control circuit 30.

When the right and left objects are simultaneously imaged, the liquid crystal display elements 2R and 2L are controlled so that the transmittance is maximized. When an operation signal for mode setting is externally supplied to the system control circuit 30. The system control circuit 30 controls the liquid crystal drive circuits 14R and 14L, whereby the liquid crystal display elements 2R and 2L are controlled so that the transmittance is maximized. Such setting of the maximum transmittance can be performed on one of the liquid crystal display elements 2R or 2L.

The left and right picked-up images stored in the memory 21 or the external memory 22 are read and processed by the video signal processing circuits 13R and 13L, and the liquid crystal driving circuits 14R and 14L
Can be displayed on the liquid crystal display elements 2R and 2L via the. Thereby, a stereoscopic image can be enjoyed. The video processing circuits 13R and 13L can perform processing such as image compression and expansion.

FIG. 2 shows another embodiment of the present invention.
In the above embodiment, the objective lens and the half mirror exist in the lens barrel. Then, the subject could be seen directly with the naked eye through the lens. However, in the second embodiment, the lens barrels 51R and 51L are prepared, and the lens barrels 51R and 51L are provided.
Inside are liquid crystal display elements 2R, 2L and eyepieces 4R, 4R.
L is provided. Then, when observing the subject to the left and right, the video images taken by the video cameras 12R and 12L are projected on the liquid crystal display elements 2R and 2L so that they can be observed. Note that the other parts are the same as those in the above embodiment, and thus are denoted by the same reference numerals.

The signals obtained by the video cameras 2R and 2L are guided to video signal processing circuits 13R and 13L, respectively. Output signals of the video signal processing circuits 13R and 13L are stored in, for example, the memory 21. Alternatively, it may be stored in the external memory 22 composed of a large-capacity semiconductor memory. Further, the signal may be transmitted to the outside through the signal input / output unit 23. Even with this device, the video cameras 12R, 12R
A stereoscopic video image can be obtained by the divergence angle of L.

The above-described apparatus is used to look inside the lens barrel through the eyepieces 4R and 4L, but various methods of use are possible.

Now, it is assumed that, for example, a mountain is being observed.
Also, it is assumed that a lot of information about mountains is input in advance to the external memory 22 so as to have a function as a picture book. Then, for example, when observing the mountain A as shown in FIG. 3, the page stored in the data stored in the external memory 22 is turned, and the information B (name or height) on the mountain A is changed to one of the two. The image can be displayed on the liquid crystal display element 2R or 2L or both. In this case, it is displayed so as to be inserted into a part of the scenery being observed.

When watching sports such as baseball, information such as a team introduction and a player profile can be read from the external memory 22 and displayed on the liquid crystal display element 2R or 2L or both.

Further, when birdwatching is performed, the names and attributes of the birds can be confirmed by using the external memory in which the information of the bird picture book is recorded. Since an image can be recorded, it is also possible to record an unknown bird.

The present invention is not limited to the above embodiment. In the above description, the information derived from the external memory 22 has been described as being video data.
The present invention is not limited to this, and audio data may be derived.

The external memory 22 shown in FIG. 4 stores video data and audio data. For example, when the information B shown in FIG. 3 is displayed, the audio switch is operated to explain the information B. And explanations are given. In this case, an audio signal processing circuit is provided.

It is also possible to store software such as a game in the external memory 22 or the memory 21. Thereby, it is also possible to enjoy a game with a three-dimensional image.

FIG. 4 shows a state in which an outer case 60, an earphone 61 and its lead wires 62 are provided.
Also, a state is shown in which the earphone 61 is stored in front of the objective lens 1L. When the earphone 61 is used, it is worn on the ear of the user as shown in FIG.

Further, in this apparatus, it is a matter of course that audio can be recorded in the external memory 22 or the memory 21. The example in FIG. 5 also shows an example in which the microphone 63 is used.

The present invention is not limited to the above embodiment. In the above embodiment, the left and right lens barrels are always described. However, one of the lens barrels may be used as a multi-telescope. With this configuration, the liquid crystal display panel can be effectively used. For example, half or most can be controlled to be in a light transmitting state, and the remaining part can be used to display information read from the memory as shown in FIG.
