A structure of video surveillance platform has been set up based on TI's TMS320DM368 (the following referred to as DM368).The driver of CMOS image sensor has been designed ,according to the valid image data read and timing requirements in the CMOS image sensor. A Aptina's CMOS image sensor AR0130 has been adopted. Acooriding its clock configuration, the ranks’ timing control, the output resolution and other design requirements, a method based on the scanning of ranks clock to divide the valid image area has been applied to set parameters for achieving the hardware device driver. The results show that the device can be normal work under the drive, and video signal outputs stable.
