Then, the image selector 31 extracts a part of the image signal from the image operation processing unit 32, performs an enlargement process, and outputs the image signal to the display controller 30 within the visual field.

In the display controller 30 in the visual field,
Upon receiving an operation signal from the operation input circuit section 28, a drive motor (not shown) of the movable prism 26 is driven, and the movable prism 26 is inserted into the optical path of the binocular tube optical system 12.

And a display image 35 of the LCD display 20 can be simultaneously observed. Therefore, during the operation, the observation direction and the observation position information can be obtained from the three-dimensional construction image information 33d as needed while performing the microscopic observation, and the current macro position information can be obtained. Then, the operator can confirm the anatomical orientation based on this information, and further changes the display image 35 of the LCD display 20 in the microscope optical observation field of view 34 to change each tomographic image other than the three-dimensional construction image 33d. Since the information 33a to 33c can also be observed, more detailed information can be obtained.

Further, the operator can easily obtain the three-dimensional construction image 33d and the other pieces of tomographic image information 33a to 33c, so that the operator can concentrate on the operation.

In the present embodiment, the image processing unit 3

Further, an operation input circuit section 28 and a communication control section 47 are connected to the microscope data setting section 46.
Further, the image calculation processing unit 43 is connected to the communication control unit 47. The communication control unit 47 is configured by a communication circuit that communicates with the image processing unit 43 based on the data of the microscope data setting unit 46.

The image operation processing unit 43 has a function of the first embodiment, and further has a means for extracting designated image information and a video signal converter, and can be controlled by a communication means. (In general, an image clipping option using a window as a workstation extension function is shown. A standard video signal conversion unit such as NTSC is provided as an output form.) The image display processing unit 30 in the visual field display controller 30 performs this image calculation processing. The section 43 is connected, and has a configuration similar to that of the first embodiment.

Next, the operation of the above configuration will be described.
In the present embodiment, at the time of surgery by the microsurgery, an image of the operative site is captured by the TV camera head 41, and a video signal of the image of the operative site is transmitted to the image calculation processing unit 43 via the TV camera controller 42.

At this time, the image display control of each LCD display 20 of the right-eye display monitor and the left-eye display monitor is performed by the control signal output from the in-view display controller 30. And each LCD
Since the image information displayed on the display 20 is displayed so as to overlap a part of the microscope observation image, the microscope optical observation image of the surgical site and the display image 35 of the LCD display 20 are obtained by looking into the eyepiece optical system 17. Can be observed at the same time.

Further, in the present embodiment, the zoom magnification is detected by the optical data detecting section 45, and the photographing magnification including the data of other optical systems is calculated by the microscope data setting section 46.
