no. 1 Embodiment approach ）

[0037] Such as figure 1 As shown, the endoscope system 1 according to the first embodiment of the present invention has an endoscope 2 inserted into the body, and a treatment instrument inserted into a treatment instrument channel (abbreviated as channel) 3 of the endoscope 2 . 4. and a light source device 5 for supplying illumination light to the endoscope 2 .

[0038] Furthermore, this endoscope system 1 has: a processor 7 as a signal processing unit that performs signal processing on an imaging unit 6 as an imaging unit provided in the endoscope 2; and a monitor 8 as a display unit that performs signal processing. An endoscopic image corresponding to the image signal generated by the processor 7 is displayed.

[0039] In addition, the light source device 5 and the processor 7 may be connected by a signal line, and the light quantity of the illumination light of the light source device 5 may be adjusted based on the brightness signal of the image signal from the processor 7...

no. 2 Embodiment approach ）

[0102] Next, refer to Figure 5 to Figure 9 A second embodiment of the present invention will be described. Figure 5 The overall configuration of an endoscope system 1B according to the second embodiment of the present invention is shown.

[0103] Figure 5 The endoscope system 1B is shown in figure 1 In the endoscope system 1 of , instead of the treatment instrument 4, a high-frequency treatment instrument 4B for performing treatment using high-frequency electric energy is used, and the high-frequency treatment instrument 4B is connected to a high-frequency power supply device 41 as a power supply device.

[0104] Furthermore, this high-frequency power supply device 41 is connected to a foot switch ( Figure 5 Abbreviated as FS) 42 connections. The high-frequency cauterization device 43 is formed by the high-frequency treatment instrument 4B, the high-frequency power supply device 41 and the foot switch 42 .

[0105] For example, like the first embodiment, this high-fre...

no. 3 Embodiment approach ）

[0165] Next, refer to Figure 10 ~ Figure 12 A third embodiment of the present invention will be described. Figure 10 The overall configuration of an endoscope system 1C according to a third embodiment of the present invention is shown.

[0166] Endoscopy System 1C in Figure 5 In the endoscope system 1B of the second embodiment shown, instead of the manual high-frequency treatment instrument 4B, an active high-frequency treatment instrument (abbreviated as high frequency disposal equipment) 4C. Furthermore, the high-frequency cauterization device 43C is formed by the high-frequency treatment instrument 4C, the high-frequency power supply device 41 and the foot switch 42 .

[0167] In addition, the endoscope system 1C of the present embodiment has a control unit 51 that controls the operation of the high-frequency treatment instrument 4C and controls the energy supply operation of the high-frequency power supply device 41 as the energy supply device. control. The control...

Abstract

An endoscope system includes an image pickup section, provided in an endoscope, which performs image pickup, a determining section that determines whether or not a specific observation object exists inside an image pickup region of the image pickup section, a recognizing section that determines whether or not the specific observation object a recognized as an image from the picked-up image in the image pickup region picked up by the image pickup section, and a low visibility determination output section that determines, when the determining section determines that the specific observation object exists inside the image pickup region and the recognizing section cannot recognize the specific observation object as an image, that the image pickup section is in a low visibility condition and outputs a low visibility determination result.

Description

technical field [0001] The present invention relates to an endoscope system and a method for judging a poor visual field by taking an image with an imaging unit of the endoscope and determining a poor visual field. Background technique [0002] In recent years, endoscopes having imaging means have been widely used for observation and diagnosis of affected tissue. In addition, an endoscope is also widely used when performing surgery under endoscopic observation with a high-frequency treatment instrument constituting a high-frequency cauterization device. [0003] Under observation by the endoscope, for example, the treatment portion near the tip of the high-frequency treatment instrument is captured within the imaging area of ​​the imaging unit, and treatments such as cauterization are performed on the affected tissue. When tissue is handled, smoke or mist is sometimes produced. [0004] Japanese Patent Application Laid-Open No. 11-318909 as a first conventional example dis...
