摘　　要：为解决NanEyeM微型图像传感器高速异步串行数据解码困难和无法直接输出RGB图像的问题,提出了一种基于动态脉宽匹配、边沿跟随的数据解码算法,该算法在对数据进行解码的同时可将Bayer图像转换为RGB图像,实现了串行图像传感器直接输出RGB图像的功能。实验表明,通过该算法可以正确稳定地对NanEyeM图像传感器的数据进行采集、解码及进行图像格式转换,为进一步推广基于该微型图像传感器的应用提供了解码方法。The high-speed asynchronous data of the NanEyeM micro image sonsor is difficult to be decoded,and RGB images can not be direct exported by this sensor.To solve these problems,a data decoding algorithm based on dynamic pulse width matching and edge following is proposed.During the process of data decoding by using this method,the Bayer image can be converted to the RGB image,and this faltills the function of direct RGB image exporting by the serial image sensor.Coprresponding experiments show that the data of NanEyem image sensor can be steadily and correctly acquired and decoded,and image format can be correctly converted subsequently.This algorithm will further facilitate promotion of applications based on the NanEyem micro image sensor.
