| Abstract: | In view of number image colleting and processing portable equipment, a real-time number image collection system based on DSP was designed. The core unit processing unit was the DSP. The system made CMOS image sensor collect the image data, and then the image data was sent to the appointed position immediately. The CPLD is the data collection logic controller. It has the function of synchronous timing controlling, and it＇s also a parallel-serial converter. It＇s shown in the experiment that the system can real-timely collect the number image at the speed of 15 per second, with size of 176 ＊ 62. The system also has the function of real-time image processing based on DSP. |
