Embodiment Construction

[0056] Such as figure 1 As shown, the endoscope system 10 of the first embodiment includes: a light source device 11 that generates light for illuminating the inside of the specimen; imaging; the processor device 13 performs image processing on the image data obtained by the imaging of the endoscope device 12; the display device 14 displays the endoscopic image and the like obtained through the image processing; and the input device 15 is configured by keyboard etc.

[0057] In the endoscope device 12 , a flexible section 17 , a bending section 18 , and a scope distal end section 19 are provided in this order from the side of the operation section 16 . Since the soft part 17 is flexible, it can bend freely. The bending portion 18 is configured to be freely bent by the rotation operation of the angle knob 16 a disposed on the operation portion 16 . Since the bending portion 18 can be bent in any direction or angle according to the site of the specimen, it is possible to dire...

Abstract

The invention provides an endoscope system and a motion control method thereof, and a processor device; therefore, even if the difference of oxygen states of blood vessels is very small, the difference can be identified to be color difference being displayed; a test body is illuminated by narrow band light of a first different absorb waveband with oxyhemoglobin having a bigger light absorption factor than reduced hemoglobin having a smaller light absorption factor, and the test body is videoed to obtain blue image data Bx. The test body, illuminated by G light having green waveband, is videoed to obtain green image data Gy; intensity ratio B / G is calculated according to the blue image data Bx and the green image data Gy; the intensity ratio B / G and the reduction of the oxygen saturation correspondingly enlarges; gain processing corresponding to the intensity ratio B / G is carried out for the blue image data Bx and the green image data Gy, thereby obtaining blue image data Bx* and green image data Gy*. And oxygen saturation image can be displayed according to the blue image data Bx* and green image data Gy*.

Description

technical field [0001] The present invention relates to an endoscope system for displaying an oxygen saturation image obtained by imaging the oxygen saturation of hemoglobin in blood, an operation control method thereof, and a processor device. Background technique [0002] In recent medical diagnosis, an endoscope system including a light source device, an endoscope device, and a processor device is widely used. In the diagnosis using this endoscope system, the insertion part of the endoscope is inserted into the specimen, and illumination light of a predetermined wavelength is used to illuminate the specimen from the tip of the endoscope. By taking an image, an endoscopic image reflecting various biological information presented on the specimen is acquired. [0003] As the endoscopic image, in addition to the normal image obtained by imaging the visible light image of the specimen illuminated with white light, different absorption coefficients obtained by different absorp...
