In this paper, we present a method to accelerate the speed of retrieving subset of uncompressed images in a database without using extra disk space. First we change the storing method: pixels of an image are saved in Hilbert order instead of Row-wise order in traditional method. After studying the property of Hilbert curve, we give a new algorithm which greatly reduces the data segment numbers on the disk. Although we have to retrieve more data than necessary, because the speed of sequential readings is much faster than the speed of random readings, our method spends about 10% less elapsed time which is showed in our simulation experiments. In some systems, the saving can be as high as 90%.
