METHOD FOR ESTIMATING POINT SPREAD FUNCTION OF BLURRED DIGITAL IMAGE, AND MEDIUM READABLE BY ONE OR A PLURALITY OF COMPUTERS AND HAVING COMPUTER-READABLE COMMAND FOR CARRYING OUT METHOD FOR ESTIMATING POINT SPREAD FUNCTION OF BLURRED DIGITAL IMAGE

摘要

PPROBLEM TO BE SOLVED: To provide a method for estimating a point spread function of a blurred digital image. PSOLUTION: One example method includes steps for capturing gyro data during an image exposure time, deriving gyro samples from the gyro data at predetermined gyro sampling times, calculating a motion vector field of the image at each gyro sampling time, approximating an overall image scene motion path by averaging motion paths of selected pixels in the image, and estimating the point spread function from the approximated overall image scene motion path.
