[0004]

In this case, in the conventional example, if there are a large number of images, these switching operations become complicated and very inconvenient. When a microscope image and an image to be displayed in a visual field are displayed on a monitor, these switching operations are also required. Further, as described above, there is no system capable of remotely controlling the display in the microscope field of view and the display on the monitor.

When an operator gives an instruction to a nurse or the like by observing an image displayed in the field of view of a microscope,
Nurses often see images different from what the surgeon is observing, so it was difficult to deal with them smoothly.

(Object of the Invention) The present invention has been made in view of the above-mentioned points, and enables a nurse or the like to observe an image equivalent to an observation image actually observed by an operator, and to perform surgery and the like. It is an object of the present invention to provide an easy-to-use system control device that can be smoothly operated.

[0007]

An eyepiece for observing an object to be observed, an eyepiece display means capable of displaying an image on the eyepiece, and a video signal for generating first and second video signals. A generator, switching means for switching and displaying an image based on the first and second video signals on the eyepiece display means, display means having a display screen of a predetermined size, and display on the eyepiece part; Control means for controlling the display means to switch the display in conjunction with each other,
By observing the image displayed on the display means, a nurse or the like can observe an image equivalent to the image observed by the operator,
It is possible to provide an environment that facilitates smoother treatment by cooperation between the surgeon and the nurse.

The content displayed on the nP screen 12b is displayed in a linked state.

Further, in this embodiment, as shown in FIG. 5, means for moving the PinP displayed in the visual field is provided. In FIG. 5, when the OFF switch is operated, the display area H1 in the visual field is at the OFF position P0 in FIG. 7, the left switch is operated at the position P1, and the central switch is operated at the position P2.
Then, when the right switch is operated, it moves to the position P3. FIG.
Although only representative positions are shown in the example, the display can be moved and displayed in more stages by pressing the button.

In this embodiment, the video switcher 1
The connection of 0 is detected, and the display of the monitor illustration (monitor state display unit 53) and the illustration of the display within the visual field (display state of the visual field display unit 54) are switched between when the connection is made and when it is not connected.

That is, when the video switcher 10 is connected, a microscope image and an endoscope image are displayed on the monitor state display section 53 as shown in FIG. Indicates that a microscope image and an endoscope image are displayed.

On the other hand, when the video switcher 10 is not connected, the mixer input 1 and 2 are simply displayed on the monitor display section 53 as shown in FIG. Only 1 indicating the Y / C input of the controller 14 is displayed.

In the present embodiment, the movement (actual screen) of the PinP screen takes time (for example, up to 6
(Approximately seconds), the screen frame blinks on the illustration to notify that it is moving.

According to the present embodiment configured as described above, the surgeon can display a desired endoscope image, an ultrasonic image, and the like in the visual field of view in addition to the microscope image in the eyepiece visual field. It can be set to display freely by selecting operation in.

When the nurse or assistant desires to maintain a display state equivalent to the image displayed in the display area H1 in the visual field in addition to the microscope image actually observed by the operator, the display interlocking switch 55 is used. By operating, the display state can be maintained.

In this state, for example, the operator is instructed to switch the image displayed in the display area H1 in the visual field to another image, and when the nurse or assistant performs the operation, the display area H1 in the visual field is displayed. The displayed image is switched to another image. Then, the PinP screen 12 on the monitor 12
The display image at b is also switched to another image in conjunction with the switching.

Therefore, the nurse or the like can always observe two images (videos) equivalent to the two images (video) observed by the surgeon. Therefore, when the surgeon gives an instruction while observing the observed image, Since nurses and the like also observe the same images, it is easy to perform procedures and operations corresponding to the instructions more smoothly, and it is easier to perform operations and the like more smoothly and in a shorter time.
