| 摘 要： | 由于成本原因，目前嵌入式产品内存配置较低，不能解码显示大尺寸JPEG图片。根据JPEG图像解码特点，提出分块解码，边解码边显示的方法。成功解码显示一幅1 100万像素的JPEG图片仅消耗112 kB内存（完全解码需29 MB内存）。该解码方法可以应用到手机、PDA等嵌入式产品中。

| Abstract: | Now, most embedded products have been configured with low memory for the reason of cost. It cannot decode and display big JPEG image. According to the characteristics of JPEG decoding, a new way was proposed to decode image part by part. As a result, it only cost 112 kB memory to successfully decode and display an 11 million pixels image which needs 29 MB to decode the image completely. Also, this method can be applied to many embedded products, such as mobile phone, PDA and so on. |
