The present invention relates to an image processing enhancement circuit for medical endoscope, including an image processing chip, a signal conversion chip and an image enhancement chip; the signal conversion chip includes a first signal conversion chip and a second signal conversion chip; the The first signal conversion chip is used to convert the bt1120 signal into a lvds signal; the second signal conversion chip is used to convert the lvds signal into a bt1120 signal; the image processing chip sends the processed image signal to the first signal conversion chip , and sent by the first signal conversion chip to the second signal conversion chip; the second signal conversion chip converts the signal and sends it to the image enhancement chip. Compared with the prior art, the present invention adds an image processing chip to the lens part to process the collected images, and adds an image enhancement chip to the background of the host to perform secondary image enhancement to make the final output image clearer.
Description
technical field [0001] The invention relates to an image processing circuit, in particular to an image processing enhancement circuit used in a medical endoscope. Background technique [0002] An endoscope is a commonly used medical device consisting of a bendable part, a light source and a set of lenses. It enters the human body through the natural channels of the human body, or through small incisions made by surgery. When in use, the endoscope is introduced into the pre-examined organs, and the changes in the relevant parts can be directly observed. [0003] Among them, the quality of the image directly affects the use effect of the endoscope. The existing electronic endoscope is generally used for observation, and the observed image is sent to an externally connected processing system for image processing. However, when the image is collected in the human body, due to various reasons inside the human body, there will be noise interference, the brightness cannot be auto...
