Micro endoscope camera module and micro endoscope having same

Abstract

The present invention relates to an ultra-small endoscope camera module comprising: a first tube body having one or more object lenses; and a second tube body supporting the first tube body from one side, wherein an image capturing means, which is adjacent to the rear of the object lenses, is provided on the inner side of the second tube body. Moreover, the present invention relates to an ultra-small endoscope camera module comprising: a body tube having an accommodation space for fixing and supporting one or more object lenses; a front tube covering the outside of the body tube; an image capturing means disposed on the rear end of the body tube; and a main tube covering the outside of the image capturing means, wherein the outside diameter of the front tube is greater than the outside diameter of the main tube. Moreover, the present invention relates to an ultra-small endoscope characterized by the aforementioned ultra-small endoscope camera module being disposed on the front end of a scope. Accordingly, the image capturing means for obtaining an image is disposed on the front end of the scope and thus a high-quality image can be obtained.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional application of U.S. patent application Ser. No. 16 / 339,280 filed Apr. 3, 2019, which is a 371 U.S. national stage of PCT / KR2017 / 012292, filed Nov. 2, 2017, which claims the priority from Korean Patent Application No. 10-2016-0165064, filed Dec. 6, 2016, the contents of each of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a micro endoscope camera module and a micro endoscope having the same.BACKGROUND OF THE INVENTION[0003]An endoscope is a kind of optical instrument and largely classified into an industrial endoscope for inspecting small enclosed spaces such as pipes and ships, and a medical endoscope for inspecting the inside the human body.[0004]Among endoscopes, the medical endoscope is an apparatus for visually checking and diagnosing the inside of the human body by directly inserting the endoscope into the human body and imaging the inside.

AI Technical Summary

Benefits of technology

The invention allows for high-quality image acquisition by placing the image capturing means at the front of a scope. Additionally, the scope is designed to prevent the tube from moving backward during assembly or use, which improves assembly efficiency and makes the scope easier to use. An illumination fiber is also included to guide a light source into the scope, which helps to downsize the scope.

Problems solved by technology

In the case of such an endoscope, there is a problem that the acquisition of a high-quality image is limited due to distortion and noise in the signal transmission process.

In the meanwhile, Korean Patent Application Publication Nos. 10-2014-0065231 and 10-2012-0101450, which are related to an electronic endoscope, are configured such that an objective lens, an image sensor, and a light source are all provided at an inner end of a scope that is inserted into the human body, so that a diameter of a tip end portion of the endoscope becomes large, whereby there is a problem that a severe rejection feeling occurs thus causing pain to a test subject when the endoscope is inserted into the human body.
