From “Editorial: Special Issue on Robot Vision”: The paper by Kim and Ueda deals with an important but little-studied problem of removing motion blur for fast-moving eyes. Saccades are very fast eye motions that allow humans to compensate for their limited field of view. Here a very fast lead zirconate titanate-driven pan-tilt camera system was employed to simulate such rapid eye motion. Motions are so fast that motion blur, caused by relative motion between the camera and an object, would prevent any possibility of scene interpretation. Using knowledge of the dynamics and input controls, the paper proposes an approach to estimate the point spread function (PSF), which is a blur kernel that describes the camera motion during an exposure window. This PSF is then used to remove motion blur and detailed experimental results are presented.
