一、Exif(Exchangeable Image File Format for Digital StillCamera)标准即数码相机可交换影像文件标准。它是由日本电子和信息技术工业协会(JEITA)制定和发布的数码相机等数码输入设备与打印机等输出设备间的一种标准,也是一个开放的图像文件标准。其原理是在数码相机拍摄的相片文件中加入打印指令和拍摄资料,通过应用拍摄数码相片时存储在图像文件中的白平衡、曝光时间等原始数据,使打印机对数字相片的色彩掌握得更加准确,从而确保打印结果能够最大限度地接近原始拍摄效果。
First, Exif (Exchangeable Image File Format for Digital StillCamera) standard digital camera that can exchange image file standards. It is a standard between digital input devices such as digital cameras and output devices such as printers, developed and released by the Japan Electronics and Information Technology Industries Association (JEITA), and is also an open image file standard. The principle is to add print instructions and shooting data to photo files shot by digital cameras. By using raw data such as white balance and exposure time stored in image files when shooting digital photos, the printer can more accurately control the color of digital photos , To ensure that the print results to maximize the original shooting effect.
