Although most digital cameras carry anti- shaking and auto-focus functions, many peop l e s t ill t ake b lur red photos due to unsteady hands. Even professional photographers may have this problem in low- light conditions. To solve the issue, image processing software currently available on the market is equipped with an image de- blurring function. But it usually just rectifies blurs by sharpening the edges of images. Prof. Jia Jiaya (right) of the Department of Computer Science and Engineering, a lover of photography, knows that sharpening the edges of images cannot really remove blurs and recover latent structure information. It simply deceives the eye by increasing the image contrast. Professor Jia believes that it is the wrong way both mathematically (theoretically) and practically to deal with blurs. To find a better solution to the problem, he and his post-doctoral fellow Dr. Xu Li (left) developed a world-leading image de-blurring
