| 摘 要： | 在嵌入式设备中,利用CCD采集高分辨率、高质量的图像是实际工程应用的需要.为此,提出了一种CCD视频图像采集系统.它由CCD图像传感器、视频输入信号处理器SAA7111A、MC9328MXL、帧/场存储体(SDRAM)以及LCD等组成,并采用双帧轮换存储方式.通过比较SOF(Start Of Frame)中断和DMA(Direct Memory Access)传送结束中断,有效地解决了图像数据丢失的问题.嵌入式CCD视频图像采集系统具有体积小、灵活性高、可以实时(25帧/s)有效地采集图像等特点.

| Abstract: | It is necessary to acquire high resolution and quality images with CCD for engineering embedded equipments. An embedded CCD video & image acquisition system based on MC9328MXL and SAA7111A, with bi-frame storing mode alternately, was proposed .The problem of image data loss was solved by comparing the number of SOF (Start Of Frame) and DMA (Direct Memory Access) transfer interrupt. This embedded CCD video & image acquisition system can collect images in real time in characteristic of small size and high flexibility. |
