Image exposure processing system and method for capsule endoscope system

Abstract

The invention discloses an image exposure processing system for a capsule endoscope system. A signal input end of a metering module is connected to an image, and a signal output end of the metering module is connected with a signal input end of an exposure judgment module; a signal output end of the exposure judgment module is connected with a signal input end of a brightness judgment module; a signal output end of the brightness judgment module is connected with a first signal input end of a gear calculation module; a signal output end of the gear calculation module is connected with a signal input end of a parameter adjustment module; and an image sensor signal acquisition amplifier gain and an image exposure time value output end of the parameter adjustment module are transported to a lighting device and a camera device, and an adjusted image sensor signal acquisition amplifier gain and an image exposure time gear value output end of the parameter adjustment module are connected to a second signal input end of the gear calculation module. The image exposure processing system and the method for the capsule endoscope system provided by the invention automatically process images which are too bright or too dark during the shooting process, and make an inspection process more efficient.

Description

technical field [0001] The invention relates to the technical field of capsule endoscope image processing, in particular to an image exposure processing system and method for a capsule endoscope system. Background technique [0002] Capsule endoscope system has been widely used in patients' digestive tract examination due to its high safety and reliability. Image display is an important link in endoscopy, and its image clarity has become an urgent need for improvement. At present, capsule endoscopy is mostly suitable for the inspection of narrow cavities such as the small intestine, so there is no need to consider image overexposure, etc. question. However, for the digestive tract organ with a large cavity such as the stomach, there is uncertainty in the position of the capsule when controlling the movement of the capsule, and the distance from the stomach wall varies. The image of the camera often has problems such as being too bright, too dark, or uneven brightness and d...

Problems solved by technology

However, the exposure processing scheme with an automatic exposure control device involved in the above-mentioned patent cannot really deal with the saturated image that is too bright or too dark in the captured image caused by lighting devices such as LEDs. To determine the supplementary light processing of the boundary image, the processing scheme has limitations and is not suitable for the processing of images captured by traditional objective lenses
