基于DSP的图像坏点处理系统的设计

Design of Image Defective Pixel of Manipulating 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;该系统采用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。主要实现三大功能,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。其为在嵌入式系统Linux平台下实现,实用性强、操作简单、扩展功能强。

Taking the advantage of the DSP which can process data very fast, this article proposes a system to deal with images defective pixel.This system uses Chipset NT96432, NOVATEK and Chipset MN34510, CCD in Video image as the core devices to manipulate defective pixel.This system is used to realize three functions：first is to collect image information;second one is to use the collected images to analyze information of defective pixel;third is to manipulate defective pixel of images.This system is based on Embedded System called Linux.It is easy to handle, practical and extendedly functional.
