Therefore, in the present invention, if the length of the side view lens is increased to improve the resolution of the endoscope image, the side view lens and the tube body are prevented from increasing the diameter of the tube body in the same axial direction as the endoscope is maintained. Convenience in use. 201228629 [Embodiment] In order to explain in detail the technical features of the present invention, the following description of the preferred embodiment and the accompanying drawings are as follows, wherein: the present invention is preferably as shown in the first to fourth figures. The image-taking structure of the multi-view endoscope provided by the actual enthalpy is electrically connected - the display (not shown) is used to display the image captured by the multi-view endoscope image acquisition structure, due to S The mysterious display is a well-known technique and will not be described here. The multi-view endoscope image capturing structure mainly comprises: a tube U, a front view lens 12, a front view sensor 13, a reflection element 14, a side view lens 15 and a side view sensor 16. The body 11, the wall of the tube forms a window in. It should be noted that the window 111 and the tube 11 may be in one piece or in an independent type. In the preferred embodiment, the independent type is taken as an example, wherein the tube body 11 has a first segment 112 and - a second segment 113 'the first segment 112 engages the second segment 113, the second segment 113 is transparent, and the window U1 is formed in the second segment. Further, the first segment 113 is made of a material that is made of a material that is made of a combination of glass and plastic. The front view lens 12 is disposed in the tube body n and is located on the front side of the window Π1. The sinusoidal sight sensor 13 is disposed in the tube body 11 and behind the front view lens 12, and receives the image captured by the front view lens 12, and the reflective element 14 is disposed on the tube body corresponding to the window In the u, the 3H reflective element 14 is located behind the front view sensor I], and the image of the side of the tube 11 is passed through the window 111 to the reflective element 14. It is worthy of a 201228629 mention that the reflective element 14 is either a reflective 稜鏡 (as shown in the first and second figures) or a flat mirror (as shown in the third and fourth figures), and the reflection The component 14 has a reflective surface 141 for the image to arrive and control the reflected image. In this embodiment, the reflective surface 141 of the reflective element 14 is at an angle of 45 degrees with the window 111. Thus, the reflective component can be reflected. 14 The image of the external environment of the window 111 at the location. Of course, if the angle between the reflecting surface 141 and the window 111 (9 is greater than 45 degrees or less than 45 degrees, the image outside the window 111 can be reflected, but there will be image deviation caused by the angle change of the angle 。. The lens 15 is disposed in the tube body 11 and disposed in the same axial direction as the tube body 11. The side view lens 15 receives the image reflected by the reflective element 14 corresponding to the reflective element 14. The side view sensor 16 is configured. In the tube body 11, the side view sensor 16 corresponds to the side view lens 15' and receives the image captured by the side view lens 15.
