Abstract

In order to remove zoom blurring caused due to the movement of the endoscope in the depth direction, it is necessary to obtain the point spread function (PSF) from the degraded image. However, the PSF of a zoom-blurred image has not been clearly modeled because zoom blurring depends on the position of the image. In this study, we propose a method to estimate the PSF of a zoom-blurred image and conduct a fundamental experiment to confirm its validity.
