[0002]
[Prior art]
2. Description of the Related Art Hitherto, it has been noted that histological observation of mucosal epithelium including cells and glandular structures in vivo (as it is alive) is important in early detection and early diagnosis of cancer. In order to meet such demands, magnifying observation at a histological observation level of magnification (about 20 to 1000 times with a general microscope) is necessary in addition to normal magnification endoscopic observation. . As an apparatus that meets such demands, an endoscope having a normal-magnification observation unit and a high-magnification magnification observation unit in parallel has been disclosed (for example, see Patent Document 1).
[0003]
According to this endoscope, a suspicious site such as a cancer cell is observed at a high magnification by a magnifying observation means while performing observation at a normal magnification by a normal observation means, so that histological observation is performed in vivo. Observations can be made.
In general, the observation result of the high magnification observed in this manner is imaged as necessary or periodically by a doctor operating the endoscope, and recorded as image information.

[Problems to be solved by the invention]
However, since each image information captured and recorded by the magnifying observation means is a cell-level magnified image, even if only the image is viewed later, it is possible to determine which part of the patient's body is the image. There is a disadvantage that it cannot be determined. Therefore, the doctor who took the enlarged image of the affected part inputs information indicating which part of the patient's body the enlarged image is in the enlarged image, or attaches an identification number to the enlarged image. It is necessary to record the information on the position of the affected part corresponding to the image on paper in the order of the identification number.

In the above embodiment, the size of the endoscope image A and the size of the high-magnification image B displayed on the second monitor 41 are different, but they may be displayed at the same size. The size may be switched. When these images A and B are combined and recorded, they may be recorded as images of the same size.
[0053]
Further, when the foot switch 51 is pressed, the amount of light transmitted from the second light source device 39 may be increased, and at the same time, the shutter speed may be rapidly switched. In high-magnification imaging, the image is likely to be blurred, so that there is the advantage that blurring can be reduced and image quality can be improved.
[0054]
When the recorded high-magnification image B or the endoscope image A is blurred, its usefulness is low, so that the blurring of the image is automatically detected when recording, and a predetermined standard is satisfied. It may be recorded in the case. In the case of the frame sequential method, a shift between the R image, the G image, and the B image may be detected, and blur correction may be performed such that the positions of the images are shifted so as to minimize the shift.

【The invention's effect】
As described above, according to the probe-type observation device and the endoscope device according to the present invention, by viewing the endoscope image recorded in association with the high-magnification image, It can be easily determined whether or not the image has been captured. As a result, the location displayed in the high-magnification image can be easily confirmed afterward as to which location in the body of the subject, and the time required for diagnosis can be reduced. Play.
