| 摘 要： | 提出了一种适用于目标快速定位和图像输出的有源图像传感器(Active Pixel Sensor,APS)的设计方案。与传统的图像传感器不同,这种传感器可以根据目标信号的位置进行区域图像输出,从而实现目标的快速定位和图像输出。阐述了这种传感器的区域划分原则和区域图像输出控制方法。通过设计和仿真测试一个48×48的面阵,验证了这种传感器的目标快速定位能力。测试结果表明,这种传感器的帧频比传统的传感器高4倍以上。

| Abstract: | An active pixel sensor (APS) for fast target detection and imaging is designed. Unlike the traditional image sensors, this sensor can output the image signals from a part of pixels in an array according to the location of the target signals. So, fast target location and image output can be implemented. The area partitioning principle and area image output control method of the sensor are described. By designing and simulating a 48×48 pixel area array, the fast target location ability of the sensor is verified. The test result shows that this new sensor has a frame rate four times higher than the traditional sensors. |
