A deburring technique for large scale motion blur images using a hybrid camera

If a camera moves fast in low light environments, large scale motion blur is induced. Algorithms for deblurring motion blur images mostly fail miserably when applied to large scale motion blur images. The motion path of the camera is complex, and the estimation of accurate point spread function(PSF) for a large scale motion blur image is always a difficult problem. Firstly, a hybrid camera which is composed by a high resolution camera and a high speed assist camera is used for deblurring large scale motion blur images. Then, an algorithm is proposed to compute the accurate PSF using the displacements. Finally, Richardson-Lucy algorithm is used for deblurring the high resolution motion blur images. The experiments show that this kind of technique can deblur large scale motion blur images efficaciously and the details of the scene such as characters can be recognized by deblurred images.
