DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a face-mounted image display device, and more particularly, to a face-mounted image display device characterized by a display control portion of an FMD image.

[0002]

2. Description of the Related Art In recent years, endoscopes capable of observing the inside of a body cavity of a patient without making an incision and performing a minimally invasive procedure by using a special treatment tool as necessary have become widespread in the medical field. It is getting. For example, biological information that cannot be observed in normal observation can visualize a lesion site on the basis of an observation image obtained by endoscopy, and can be observed in detail. In addition, it is possible to easily compare and confirm the secular change and the previous inspection by recording and printing.
Furthermore, it becomes possible to treat a disease that would otherwise require a surgical laparotomy in a minimally invasive manner under an endoscope, thereby reducing the social burden on the patient by shortening the length of hospital stay and the like.
For this reason, endoscopic surgery, which is a minimally invasive technique, is expected to develop in the future.

[0003] An image observed by an electronic endoscope is displayed on an observation monitor. Since this observation monitor is usually arranged at a fixed position, the operator inserts / removes the endoscope while keeping his / her gaze fixed. .

[0004] Therefore, a face-mounted display device (hereinafter referred to as FMD (Face Mou), which is used by being worn on the head or face.
Inspection / observation is being carried out without using an unreasonable posture by using nt display). The FMD is a head-mounted display device (He
ad Mount Display).

[0005] This FMD is intended to observe an image just before the eyes by a small image display device installed at a position corresponding to the left and right eyes. Performing endoscopic surgery with the FMD attached is expected to allow more accurate procedures because the surgery can be performed while viewing a stereoscopic image of, for example, a lesion. On the other hand, stereoscopic video observation is not always necessary at the medical site, and the endoscope image is always visible regardless of the operator's direction, and the operator's posture is not restricted. Due to the nature, the number of cases where the FMD is used in place of the observation monitor in normal observation is increasing.

On the other hand, an endoscope having a flexible insertion portion can be inserted into a bent body cavity to diagnose an organ deep in the body cavity without making an incision, and a treatment tool can be inserted into a channel as necessary. To remove polyps and the like.

In this case, for example, as in the case of examining the lower gastrointestinal tract from the anal side, some skill may be required to smoothly insert the insertion portion into a bent body cavity.

In other words, when the insertion operation is being performed, it is necessary to perform an operation such as bending a bending portion provided on the insertion portion in accordance with the bending of the conduit so as to perform a smooth insertion. It is convenient to be able to know the position of the distal end and the like in the body cavity, the current bending state of the insertion portion, and the like.

[0009] Accordingly, Japanese Patent Application No. Hei.
In Japanese Patent Application No. 0-0607575, a magnetic field generation signal is supplied to a source coil as a plurality of magnetic generating elements incorporated in an endoscope, a sense coil as a plurality of magnetic detecting elements arranged in a coil unit, and a source coil. And a control unit for amplifying and analyzing a detection signal generated in the sense coil to calculate the position of each sense coil, and a monitor for displaying the shape of the endoscope generated by the control unit. Endoscope shape detection device).

Such an endoscope shape detecting apparatus is used in combination with an endoscope apparatus for displaying an endoscope image obtained by the endoscope on an observation monitor, and displays the detected endoscope shape on the shape display. It is displayed on a monitor and used to assist the endoscope insertion operation.

[0011]
