影像技术的进展对环境保护的影响

影像技术的发展也对环境保护带来很大的改善，传统的银盐感光材料的生产和应用过程会排放一些有害的气体和污水，对环境造成一定的危害，虽然一些大型的企业会建立专门的环保设施，处理排放的气体和废水，但是一些小型的用户就很难做到。基于CCD和CMOS的新型数字影像材料的生产和应用一般不会产生环境污染，但是拍摄以后加工成照片时，不管是采用传统彩色相纸，或者喷墨打印，也都会产生一定的环境污染，须要采取相应的预防措施。

Influence of Imaging Technology Progress on Environment Protection

The progress of imaging technology brings very beneficial influence on the environment protection; the production and processing of traditional silver halides salts photographic materials can cause miscellaneous environment pollution problems; although generally big or medium firms may build relevant environment department to treat their waste water, gas and sludge, most small-size users cannot fulfill this requirement. New digital imaging materials based on CCD or CMOS normally don＇t cause environment problems during their production and use, but their post shooting processing may cause environment pollution no matter through inkjet printing or color photographic paper, thus also needs relevant environment protection devices.
