Video capturing, processing and enhancing device for medical endoscope

The invention relates to a video capturing, processing and enhancing device for a medical endoscope. The video capturing, processing and enhancing device comprises a video capturing chip, an image processing chip and an image enhancing chip. The video capturing chip sends acquired video data to the image processing chip for processing, and the image processing chip processes the image data and then sends to the image enhancing chip for enhancement. Compared with the prior art, the video capturing, processing and enhancing device has the advantages that since the video capturing chip is divided into a plurality of functional modules which are in independent coordinative operation, low power consumption and low illuminance can be realized, and definition of output pictures can be increased. Furthermore, by addition of the image processing chip to a lens portion to realize processing of acquired images and addition of the image enhancing chip to a mainframe background to realize secondary image enhancement, the finally output images are higher in definition.
