Problems solved by technology

[0006] As a result, in the technology disclosed in Japanese Patent Application Laid-Open No. 7-155289, when the endoscope is inserted according to the setting result of the target position, a part of the front end surface of the endoscope does not contact with the folded wall of the intestinal tract or the like. The possibility of contact becomes high, so the endoscope cannot be inserted smoothly

Embodiment Construction

[0019] First, the arithmetic processing unit acquires the original image ( figure 1 Step S1).

[0020] Next, the arithmetic processing unit functioning as the position setting unit extracts the figure 1 After the dark area in the original image acquired in step S1, the center of the dark area is set as the bending target position of the bending portion by adopting known processing ( figure 1 step S2). Through such processing, the pixel position in the original image is set as the warping target position.

[0021] In addition, the arithmetic processing unit sets the circle of the simulated front end surface at the center of the acquired original image ( figure 1 Step S3), and then extract the brightest region in the original image and the boundary line of the brightest region ( figure 1 step S4).

[0022] Here, a specific example of processing performed when extracting the brightest region will be described.

[0023] First, the arithmetic processing unit divides the origi...

Abstract

The invention provides a micro-traumatic superfine endoscope system which is provided with an endoscope. The endoscope is provided with a photographing part, a position setting part and a position revising part, wherein the photographing part is used for photographing a photographed object in a body cavity; the position setting part sets a position in an image according to information obtained by the image of the photographed object; and the position revising part revises one position set in the position setting part according to other information obtained from the image, so that other positions which are different with the position can be set.

Description

technical field [0001] The invention relates to a minimally invasive ultrafine endoscope system, in particular to a minimally invasive ultrafine endoscope system capable of supporting the insertion of an endoscope into a body cavity or other subject. [0002] Background technique [0003] Endoscopes have been widely used in the medical field and industrial fields. For example, in the medical field, endoscopes are used for observation of living tissues in body cavities and various treatments. [0004] In addition, Japanese Patent Application Laid-Open No. 7-155289 discloses a technique for extracting a dark region in an observation image obtained by an endoscope and appropriately setting a target position when the endoscope is inserted (traveling). direction and movement amount), so that the center position of the dark area becomes the center position of the observed image. [0005] However, the technique disclosed in Japanese Patent Application Laid-Open No. 7-155289 merel...
