Abstract—The existing medical endoscope is integrated with a small fixed focus lens in front of small data pipe. After endoscope into disease region, the fixed lens can’t transform the focal length according to environment, which leads to surrounding environment can’t be seen in the process of endoscopy. This will cause irreversible damage of lesion area. We use the function of first shooting and then focusing and automatic focusing to complete endoscopic process, and transform the environment from fuzzy to high definite by software to adjust focus. It avoids the damage caused by the aggressive of the medical endoscope. At the same time, we design a direction light transmission channel optical fiber to project the direction light for environment that light is not enough, which make the light sufficient and make the endoscopic channel clear. Our medical endoscope shoots and stores video in the endoscopic processing. It also can see clearly everything after completed endoscopic processing, so as to realize multiple diagnoses by one video. The video shot by our endoscope can be used as treatment evaluation materials in the whole treatment process. We use the light video camera focus function in the medical endoscope field firstly. Medical endoscope technical filed is expanded and improved.
Index Terms—Light field capture, medical light field camera, micro lens array of light field, projection direction light.
