Abstract

Abstract:

The system uses embedded microprocessor S3C2440 and Linux as the core platform. The application programming interface V4L2 and Qt/Embedded library are two key technologies to realize image acquisition, realtime display and JPEG picture saving by using USB camera. This design of image acquisition and transmission is a low power consumption, high reliability and inexpensive system, which achieves encoding or decoding of images by libjpeg library and remote transmission of Ethernet.
