Abstract
A method and an apparatus for designing an image restoration filter and a method and an apparatus for restoring an image by using the image restoration filter are provided. A test image is captured by an imaging system to obtain image information of the test image. The image restoration filter is then calculated according to original image information of the test image and the image information obtained by the imaging system through a numerical method, such that the obtained image information after being processed by the image restoration filter has a better similarity to the original image information. Thereafter, an image captured by the imaging system is processed by using the image restoration filter as a kernel, so as to resolve the problems of image blur and distortion caused by the optical path and the imaging system.
