在电子影像的处理过程中,最常用到的输入设备应该是数码相机和扫描仪,比较其经济性及功能性,数码相机在影像的捕捉上机动性更强,而扫描仪在输入已有图片及文字方面更胜一筹。同样价位的数码相机跟扫描仪相比,用扫描仪处理的图片精度更高。按工作原理的不同,扫描仪分为五种,有手持式、平板式、胶片专用、滚筒式和CIS扫描仪,目前市场上最受大家欢迎的图像输入设备就数平台式扫描仪了。扫描仪虽好,使用起来却不容易,从安装、使用,到保养都有很多讲究。
In the process of electronic image processing, the most commonly used input devices should be digital cameras and scanners, more economical and functional, digital camera capture on the image more mobile, and the scanner in the input image has been And text better. The same price of digital cameras compared with the scanner, scanner with higher accuracy of the pictures. According to the different working principle, the scanner is divided into five kinds, there are hand-held, flat-panel, film-specific, roller and CIS scanner, the most popular image input devices on the market on the number of platform scanners. Although the scanner is good, it is not easy to use, from installation, use, to maintain a lot of stress.
