| Abstract: | This paper introduced a processor(i.MX21)-based video acquisition and coding system,which obtained image data acquired by CMOS Sensor from CSI interface,and compressed the data into MPEG4 format using the Enhanced Multimedia Accelerator(eMMA).Finally,we focused on the implementation of CSI driver and video data acquisition and coding. |
