DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an endoscope system capable of determining the type of endoscope connected to an external camera and displaying the information.

[Conventional technology 1] In recent years, electronic endoscopes that use solid-state color elements such as charge-coupled devices (CODs) instead of image guides that transmit optical images have been put into practical use, and internal images captured on a TV monitor have been put into practical use. It is possible to display endoscopic images.

In addition, an external TV camera with a built-in image carrier such as COD is attached to the eyepiece of an optical endoscope that uses a conventional image guide, and an i-image of the endoscope is displayed on the TV monitor. Things started to happen.

By the way, this external camera can be connected to multiple types of fiberscopes depending on the model. Furthermore, when recording observed images as data, there is a desire to include the number of image guides, observed parts, etc. in the data. In conventional devices, it has been considered to manually include the number of image guides, observation areas, etc. in the data.

[Problems to be Solved by the Invention] However, when attempting to record data regarding the fiberscope by manual operation, the recording operation becomes complicated, time consuming, and troublesome.

[Object of the Invention] The present invention has been made in view of the above circumstances, and provides an endoscope system that can record data regarding an optical endoscope connected to a T'V camera with simple operations. The purpose is to

As shown in FIG. 1, the endoscope system of this embodiment includes a light source device 10, a fiberscope 20, an external TV camera 30, a camera control unit 40, and a display device 50. .

The fiberscope 20 includes an elongated insertion section 27, a large-diameter operation section 28 connected to the rear of the insertion section 27,
A universal goople 29 is provided extending from the side of the large-diameter operating portion 28. A light guide 21 for transmitting illumination light is inserted into the insertion portion 27 and the two unipar length cables, and the light guide 21 transmits illumination light.
By connecting a connector (not shown) provided at the tip of the light guide 21 to the light source device 10, the light guide 21 can be connected to the light guide 21. 8
White light emitted from a light source lamp 11, such as a xenon lamp, is irradiated onto the window surface, the amount of which is adjusted by a dimming light shielding member 12, and condensed by a condenser lens 13. and. This light guide 21 directs illumination light to the insertion section 27.
The light is transmitted to the exit end face on the tip side of the light beam, and is emitted to the object side via the light distribution lens 22. The object illuminated by this illumination light is imaged by the objective lens 23 on the incident end surface of the image guide 24 passed through the insertion portion 27 by 1Φ.

The output end surface of the image guide 24 is connected to the operating section 28.
It is placed opposite to an imaging lens 31 in an external TV camera 30 that is detachably attached to an eyepiece provided on the rear end side, and the optical image transmitted by this imaging lens 31 is converted into a CC [ ) 33 image plane. For example, an RGB mosaic filter 32 is disposed on the image carrying surface of the CCD 33.

On the other hand, the light source device 10 includes a power supply 14 for supplying power to the lamp 11, a dimming circuit 15 for controlling the light shielding part 12, and 1) supplying air to the fiber cob 20, etc. A pump 16 is also installed, and this pump 16
Air, etc. sent from the universal cable and the insertion portion 27 are supplied through an air supply conduit 25 that is passed through the inside of the universal cable and the inside of the insertion portion 27.

The external TV camera 30 is also provided with a COD driver 34 for controlling the timing of the operation of the CCD 33, and further includes a scope detection circuit into which a discrimination signal of the scope detected by the scope detection means 26 is input. There are 35. Each signal output from the scope detection circuit 35 and the COD driver 34 is transmitted to the CCU, which also acts as an endoscope information output means.
40. Further, the operation timings of the scope detection circuit 35 and the COD driver 34 are controlled by the CCU 40. The image signals subjected to various processing by the CCU 40 are displayed on the display device 50.

By the way, the scope discrimination circuit 26 has a configuration as shown in FIG. Figure 2 (A) shows an example in which the type of scope (insertion site, series, series name, etc.) is determined by a combination of any N determination resistors of R8, RB, ...RN. , and (B) shows an example in which the scope is determined by combining connection and release.

Note that this scope discrimination circuit 26 and the scope detection port t
II35 constitutes a detection means.

The light emitted from the lamp 11 of the light source section 10 is focused on the incident end surface of the light guide 31 by the condensing lens 12,
This light guide 31 transmits light to the illumination lens 3.
The object is irradiated via the light source 2. An image of this illumination light is formed on the incident end surface of the image guide 34 via the objective lens 33, and the image guide 34 is used to monitor the external TV.
guided to camera 20. Then, the image is formed on the C0D 23 by the imaging optical system 21, and photoelectrically converted by the CCD 23. Note that the optical image signal from the imaging optical system 21 is separated into three color signals by a color mosaic filter 22 before being imaged on the C0D 23. Then, the photoelectrically converted image signal is sent to the COD driver 24
is read out by applying a drive signal from the CCU.

Scope information from ('GIF-Q in Figures 1 and 3)
IO°' is also displayed. That is, when the scope discriminating circuit 26 is configured as shown in FIG. The type is determined, and the information is sent to the CCU 40 and displayed on the display device 50 together with the bending image. When the CCU 40 instructs to record an image, information regarding the fiberscope 20 is also stored.

Note that even when the scope discriminating means 26 has a configuration as shown in FIG. Information is output to CCU 40.

As mentioned above, according to the first embodiment,
The type of scope connected to the external TV camera is determined and output on the screen at the same time as the normal image, so the operator can easily know the type of scope connected to the external TV camera. can.

Furthermore, since information regarding the type of score is automatically recorded when recording an image, the type of scope used can be saved as data along with the image.
