Abstract
Recently, digital still cameras are very popular, and many people have portable devices with camera module such as camera phone, PDA, and other devices. Each of them usually wants to take a picture for remembrance at any time. But some of their images have poor quality. Therefore we need a robust algorithm to reconstruct a high-resolution image, so we will introduce our method to conquer different image motion situations. But in real scene, super-resolution algorithm may suffer many difficulties such as camera shutter speed limitation, image jitter, fast motion objects, and so on. Because above situations will result in reduced image quality, we will focus on motion estimation which is the most important part in super-resolution algorithm. We propose an alternate approach using image subtraction method to estimate motion objects. Therefore we can find accurate object motion range to get a better result.
