Abstract

The present invention relates to a method and system for obtaining a point spread function for deblurring image data captured by an imaging device comprising a motion sensor. First, motion path values indicating the motion of the imaging device during the exposure time are acquired. The motion path values of the imaging device are then projected onto the sensor plane and for each sensor pixel the projected motion path values are integrated over time. Said integrated value represents for each sensor pixel an initial estimate of the point spread function. Optionally, the size of the point spread function can also be estimated based on the distance of the focused object and taken into account during the projecting step.
