Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an observation device,
Or an observation device that improves the efficiency of stereoscopic observation of subjects
It is about. [0002] Conventionally, for example, in a stereoscopic endoscope or the like.
As a stereoscopic observation device, left and right observation on one monitor
Project images alternately and separate the left and right images
Wear eyeglasses using a polarizing plate on the face,
3D that captures the observation image of the eye into the left and right eyes of the observer
(3D) Observation equipment and two monitors arranged side by side
The images are projected on the left and right eyes,
By guiding images, you can observe each monitor image.
Sensing device is provided. [0003] Then, when using the two monitors,
The observation device has a small monitor in the shape of glasses and
A face-mounted image display device to be worn (hereinafter referred to as FMD)
And Japanese Patent Application Laid-Open No. 10-142551.
Head-mounted image display device (hereinafter referred to as HMD)
Is being planned. The HMD is mounted on the head of an observer,
Arrange the image display so that it is positioned on the face, and left and right independent
Image displayed on a small liquid crystal display (LCD)
It is designed so that an image can be directly observed with eyes. [0005] However, the above-mentioned one unit
Use a monitor and observe the image using the polarizing glasses.
With conventional observation equipment, the image becomes dark,
Besides the difficulty of using
There is. An FM using the two monitors described above.
During surgery, the surgeon's face is used for stereoscopic observation of D and HMD.
As it is worn on the face or head, it is not only annoying,
The weight causes fatigue. And once you put it on
If this happens, the face of the observer, especially in front of the eyes, contains images containing optical systems.
Because it will be covered by the image display section,
For example, when viewing an X-ray photograph, etc., F
MD or HMD must be removed,
The mounting operation becomes very troublesome. On the other hand, in order to eliminate the above problems,
In addition, put the FMD or HMD in the operating room instead of the face or head.
A method of supporting the stand provided is conceivable. Only
In this case, the observation is performed by changing the observation position with the endoscope.
Hand to change the patient's position with respect to the operating table.
Must be moved to the optimal position for surgical procedures.
Intensive work is required, which leads to prolonged operation time.
Problem arises. The present invention has been made in view of the above points.
Therefore, two monitors for stereoscopic observation by the operating surgeon
With the monitor supported by the stand,
When changing the position of the operator with respect to the operating table with the change
Does not require any special work and causes operator fatigue
The aim is to provide no observation device. [0009] The above-mentioned object is achieved.
Therefore, the observation device according to the present invention can capture an image of a subject.
A second supporting means for movably supporting the imaging means in the predetermined first space;
1 supporting means, and the supporting means supported by the first supporting means.
Subject image can be displayed based on the imaging signal from the imaging unit
Display means and the display means are moved within a predetermined second space.
Second support means for movably supporting the first support means;
The amount of movement of the second support means is determined based on the amount of movement of the step.
And movement control means for controlling the movement. In the above arrangement, the first supporting means is provided with
Moving the imaging means capable of imaging the body in a predetermined first space;
The display means is supported by the first support means.
The subject image based on the imaging signal from the imaging means
Display means, and the second support means displays the display means at a predetermined second
It is movably supported in the space. And movement control means
Is based on the amount of movement of the first support means.
Of the supporting means is controlled. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will now be described with reference to the drawings.
