The design of real-time image sensor based on JPEG2000 is introduced. Image data is compressed into JPEG2000 format data by ADV212 encoder, then detected and identified by micro controller. Based on the circuit, the image sensor has the advantages of high compression ratio, low bit rate, small size and flexible control. The image sensor which is applied in security and monitoring system can acquire the target image information accurately and rapidly.%提出一种基于JPEG2000算法的实时图像传感器设计方案,将采集到的图像数据通过编码器ADV212压缩为JPEG2000格式,再由微控器对目标进行探测和识别.该图像传感器具有高压缩率、低比特速率、体积小巧以及控制灵活等特点,并实际应用于安防、监控领域,能够快速、准确地获取目标图像信息.
