Capsule endoscope, endoscope system and image acquisition method for endoscope

Abstract

The embodiments of the invention disclose a capsule endoscope, an endoscope system and an image acquisition method for the endoscope. The capsule endoscope comprises a shell; an image acquisition system, comprising a lens and an image processing device; and a visual angle control device connected with the image acquisition system, wherein the visual angle control device is used for controlling a visual field angle mode of the capsule endoscope according to attitude information on the capsule endoscope, and the image acquisition system acquires images in different visual field angle ranges whenthe capsule endoscope is in different visual field angle modes; the lens is arranged at the end part of the capsule endoscope and acquires first image information through a pupil entrance visual field angle; and the image processing device is used for processing the first image information according to the visual field angle mode so as to obtain second image information. According to the capsuleendoscope, the endoscope system and the image acquisition method, disclosed by the embodiments of the invention, the visual field angle mode can be switched to acquire images of higher quality, reducedistortion of the images and facilitate image mosaicking; and meanwhile, a data transmission quantity is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a capsule endoscope, an endoscope system and an image acquisition method for the endoscope. Background technique [0002] At present, due to the painless and non-invasive advantages of using the capsule endoscope to capture images for medical diagnosis, the capsule endoscope is gradually used in clinical diagnosis. [0003] Existing capsule endoscopes include housings, lenses, magnets, batteries, and antennas. After the capsule endoscope is taken orally by the subject, it enters the stomach or intestinal tract, and takes close-range images of the inner wall of the stomach or intestine through its lens, and transmits the captured images to the outside of the body through the antenna, which is convenient for doctors to perform clinical diagnosis. Under the control of an external magnet, the magnet can move with the capsule endoscope. In order to obtain image data comp...

Problems solved by technology

However, the lens functions of existing capsule endoscopes are often relatively single, and cannot take into account the clarity and integrity of image acquisition.

[0005] In addition, due to the large amount of data of the image captured by the larger field of view, the amount of data transmission between the capsule endoscope and the external equipment is large and the data transmission speed is slow
