In this paper, we propose an active vision system which has variable PSF. The system consists of a deformable mirror, an aperture stop and four lenses. The deformable mirror is placed at the pupil plane and its effective size is determined by the aperture stop at the conjugate position of the mirror. We try to enhance the image resolution using this system. We make four different mirror surface shapes to take four regularly shifted images and use super-resolution algorithm to synthesize higher resolution image from the low resolution observations. It is demonstrated that our method can be used to enhance image resolution which is limited by CCD cell size. We compare the result with the real image and some discussion about algorithmic parameters follows.
