Capsule type endoscope and image processing method thereof

Abstract

The invention discloses a capsule type endoscope and an image processing method thereof and relates to the technical field of medical electronic equipment. The capsule type endoscope comprises an image acquisition device used for acquiring images, an image processing module used for performing synthesis and nondestructive compression for image data, and a wireless transmitting device used for emitting out compressed image data in a wireless manner. According to the capsule type endoscope and the image processing method thereof, capsule type endoscope images with different exposure degrees are acquired and synthesized to expand the dynamic range of the capsule type endoscope image, which in turn enlarges the indication range of the image scene and enhances specific features of a high light area and a shaded area of the image, so as to improve the image quality. The image can be sent out after being synthesized by the capsule type endoscope so as to obtain high-dynamic range image of the capsule type endoscope and to provide images containing more information and details for users.

Description

technical field [0001] The invention relates to the technical field of medical electronic equipment, in particular to a capsule endoscope and an image processing method thereof. Background technique [0002] The wireless capsule endoscope can non-invasively obtain images of the entire digestive tract, greatly expanding the doctor's diagnostic vision. It can overcome the shortcomings of traditional push-type endoscopes. It is non-invasive and painless. It can enter the intestinal tract by swallowing, and can take and analyze specific and non-specific position images of the esophagus, stomach, small intestine and large intestine, and realize the entire digestive tract. The system checks. However, since the capsule endoscope moves along with the peristalsis of the stomach or intestinal tract in the digestive tract, when the lens and the flashlight of the capsule endoscope are far away from the wall of the digestive tract, the images taken are relatively dark; When the lens an...

Problems solved by technology

However, since the capsule endoscope moves along with the peristalsis of the stomach or intestinal tract in the digestive tract, when the lens and flashlight of the capsule endoscope are far away from the wall of the digestive tract, the images taken are relatively dark; When the lens and flash of the endoscope are close to the wall of the digestive tract, the captured image is brighter and halos will appear; in areas that are too bright, the image sensor is saturated output, and in areas that are too dark, due to reading noise, etc. The subject cannot be distinguished at all, and the existing capsule endoscope cannot guarantee the image quality because the dynamic range of similar scenes exceeds the dynamic range of the image sensor
