| Abstract: | How to obtain the real-time image data,corresponding process the image and show it on LCD,which is based on S3C2440 and Embedded system,is described.The API provided by V4L2 of Embedded Linux is used to capture the image and then decompress the image data and convert it into the appropriate format with the ability of high-speed operation by 2440,and the video on LCD by using the Framebuffer. |
