The main work in this dissertation is as follows : 1 . comparing the visual inspection systems at present in the world , an application model of the image processor is designed . the processor combines a reconfiguration hardware fpga and a software - programmable dsp 开展的主要研究工作如下：一、比较了目前国内外已有的几种视觉检测系统，设计了一种用于视觉检测的实时图像处理器的应用模型，采用fpga + dsp的混合结构，既能保证图像处理的准确性，又能保证较高的计算性能。
At first , we introduce the working flow of ir image processing and the structure of the image processor , then we present the goal of the design : image pre - processing and data communication . in the part of the image pre - processing , the factors causing the nonuniformity of fpas are analyzed particularly , and several . resolutions are presented , which characters are illustrated at last . according to the design requirement , we decided to implement the two - point nonuniformity correction method in fpga 在图像预处理部分，首先就红外成像传感器非均匀性的成因进行了详细分析，总结了红外成像传感器非均匀性校正的主要方法，分析了各种方法的优缺点；根据成像制导信息处理机实时处理的要求，利用现场可编程门阵列实现了基于浮点运算的两点法非均匀性校正模块。
Since then , jeilin has developed many important core technologies such as jpeg codec , usb device controller , high - performance image processor , dsc controller , memory card interface controller , ide interface controller , tv encoder , and mpeg - 4 codec , etc . with these core technologies , jeilin has successfully promoted cost - effective solutions for customer s products such as pc camera , web camera , dsc , photo card reader and digital picture frame 杰霖科技致力于影像与多媒体ic的设计与研发，已成功开发多种pc周边控制晶片多媒体影音控制晶片及客户委托之应用ic如通讯产品asic等研发。针对影像处理技术， jpeg codec压缩及解压缩技术mpeg 4 codec系统整合tv encoder介面技术usb 2 . 0介面技术及ide介面技术，皆有丰富的开发与整合的成功经验，并极力推陈出新。
