基于DSP的图像坏点处理系统设计

The Design of Images Defective Pixel of Manipulate Systems Based on DSP

利用DSP处理数据速度快的特点,提出了基于DSP的图像坏点处理设计方法。系统采用NOVATEK系列芯片NT96432和视频采集CCD系列芯片MN34510为中心器件来设计坏点处理。该系统主要实现了三大功能:一是采集图像信息;二是根据采集到的图像分析坏点信息;三是处理图像坏点。该系统在嵌入式系统Linux平台下实现,实用性强、操作简单、扩展功能强。

According to the characteristics of the DSP which can manipulate the data very fast. To improve design technique based on images defective pixel of manipulate systems of DSP, this system uses Chipset NT96432, NOVATEK and Chipset MN34510, CCD in Video image as the core devices to design defective pixel of manipulate. This system is mainly used to realize three functions： to collect image informa- tion, to use the collected images to analyze information of defective pixel, and to manipulate defective pixel of images. This system with the help of embedded system called Linux is very simple, practical and extendedly functional.
