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.

Image Capturing

In present paper, a DSP-based image capturing and transmitting system is described. As a shortage of peripherals on DSP, external image capturing and data transmitting components are needed in this case. A CMOS image sensor was used to capture images, and an Ethernet MAC controller with PHY was used to transmit image data. In addition, a CPLD was used as the co-controller for timing control. ARP, IP and UDP were functioning during data transmitting through Ethernet. The Driving Mechanism of two main chips and implementing of the protocols were described in detail. Images displayed on the PC show that the system provids good performance. The system is low-cost, simple and low-power.

In order to precisely measure the fineness of raw silk, some features of raw silk are analyzed. By use of Fresnel principle, diffractions caused by raw silk in different conditions are analyzed and simulated. Image data of the fineness of raw silk measured by CMOS image sensor is analyzed for obtaining precise result. Finally, some suggestions are proposed for photoelectric measuring the fineness of raw silk.

High Definition

A high-definition imaging and processing system is presented, which consists of a color CMOS image sensor, SRAM, CPLD and DSP. The CPLD implements the logic and timing control to the system. SRAM stores the image data, and DSP controls the image acquisition system through the SCCB. The timing sequence of the CMOS image sensor OV9620 is analyzed. The imaging part and the high speed image data memory unit are designed. The hardware design of the imaging system and processing algorithm are given. Because the CMOS digital cameras use color filter arrays to sample different spectral components, such as red, green, and blue, at the location of each pixel only one color sample is taken, and the other colors must be interpolated from neighboring samples. We use the edge-oriented adaptive interpolation algorithm for the edge pixels and bilinear interpolation algorithm for the non-edge pixels to improve the visual image quality. This method can get high processing speed, decrease the computational complexity, and effectively preserve the image edges.
