Abstract

The present invention discloses one kind of radio endoscope capsule based on JPEG2000 including one CPU set in the center of the casing. The radio endoscope capsule features the CPU with output connected electrically to an image sensor, an image compression module, a data buffering memory, an RF transmitter and a controllable lighting device, and input connected electrically to a low frequency receiver; and the successive electric connection of the optical system, the image sensor, the image compression module, the data buffering memory and the RF transmitter. The radio endoscope capsule has no magnetically controlled power switch, no inconvenience in storing and transportation and low power consumption device resulting in microampere level current consumption of the system and long effective work time; and can send image data and change the image decoding parameter according to requirement.

Description

technical field [0001] The invention relates to an instrument for detecting the digestive tract of a human body, in particular to an on-demand wireless endoscope capsule using an electronic endoscope system and based on a JPEG2000 compression algorithm. Background technique [0002] For the human digestive tract including the esophagus, stomach, small intestine, large intestine, etc., because it is inside the human body, it has always been difficult and often inaccurate to detect its lesion parts; currently the most commonly used, The most direct method is endoscopy. Endoscope has developed from wired form (endoscopic image transmission) to wireless form, and wireless endoscope gradually adapts to the needs of the market because of its ability to reduce the discomfort of the examinee and its high resolution. [0003] The invention patents related to wireless two-way endoscope capsules applied in China mainly include: "Two-way digital wireless endoscope system" and its worki...
