1. An endoscope system, comprising an object lens module, a relay module, an eye lens module, an optical interface light path module, and a digital ultra-high-definition camera, which are sequentially arranged along a light path direction, wherein, during design of the endoscope system, an image for an object at a viewing distance formed by the object lens module is projected to the optical interface light path module in a form of non-parallel light after passing through the relay module and the eye lens module, and an exit pupil of the eye lens module is used as an entrance pupil of the optical interface light path module.
