由于摄像头输出图像数据量大,像素同步信号PCLK频率高,无法被众多学者所熟知的51单片机采集到.提出了以牺牲程序空间来换取执行速度的程序框架,提高了数据采集效率与速度.为避免图像错位,提出将行中断设为高优先级.为避免采集到无效数据,指出行采集时间段必须与行中断信号高电平区间对齐.实验结果表明,51单片机运行此程序能够很好的采集摄像头图像数据,给用户带来方便的同时也节约了FIFO成本.%Because the camera output image data quantity is big and with high PCLK pixel synchronization signal frequency, it cannot be collected by 51 single-chip microcomputer which is known for many scholars. The application framework of program space for execution speed was proposed to improve the speed of data acquisition. To avoid dislocation images,the row set is put forward as high priority. In order to avoid invalid data collected,it is pointed out that line collection period must be line with the interrupt signal high level range alignment. The experi-mental results show that the 51 single-chip computer to run this program can collect a good camera image data,bring convenience to the user and at the same time also save on cost of FIFO.
