Due to memory limitation, the displaying and processing of the oversized images have been a bottleneck for various applications, which is a hot research spot in the image processing field. The traditional methods are almost based on the BMP format to generate oversized images, of which the time and space complexity are very high. In this paper, we have deeply analyzed the encoding scheme of JPEG image and proposed an oversized image generation method based on stitching JPEG file streams. According to this method, the oversized images are block plotted and then transformed and saved as JPEG format files respectively. In the end, the block JPEG files are then combined into an integrated JPEG image. The experiment results show that, our method can effectively improve the speed of oversized image generation and reduce the memory consumption. The time and space performance of our method are better than existing methods.
