A microendoscope is disclosed. According to an embodiment of the present invention, the microendoscope provides an image of a subject to an image output device having an image sensor which electrically converts the image of the subject entered with light into a signal. The microendoscope of the present invention comprises: an object lens located on the front end, where the image of the subject is formed; an image fiber combined with the rear end of the object lens and made of an optical fiber bundle for images, to convey the image of the subject formed on the object lens with light; and an optical zoom lens unit located at the rear end of the image fiber, and having two or more image twist lenses, where the image of the subject outputted by the image fiber passes through the image twist lens groups and twists and the magnification of the size is controlled through interval control between the image twist lens groups to enter the image of the subject into the image sensor. The optical fiber for the image and the pixel of the image sensor are matched one to one as the magnification of the optical zoom lens unit is adjusted. Thus, the grid pattern appearing in the subject image outputted by the image fiber is reduced. |
