/**
* 注：
* Image Description 图像描述、来源. 指生成图像的工具
* Artist 作者 有些相机可以输入使用者的名字
* Make 生产者 指产品生产厂家
* Model 型号 指设备型号
* Orientation方向 有的相机支持，有的不支持
* XResolution/YResolution X/Y方向分辨率 本栏目已有专门条目解释此问题。
* ResolutionUnit分辨率单位 一般为PPI
* Software软件 显示固件Firmware版本
* DateTime日期和时间
* YCbCrPositioning 色相定位
* ExifOffsetExif信息位置，定义Exif在信息在文件中的写入，有些软件不显示。
* ExposureTime 曝光时间 即快门速度
* FNumber光圈系数
* ExposureProgram曝光程序 指程序式自动曝光的设置，各相机不同,可能是Sutter Priority（快门优先）、Aperture Priority（快门优先）等等。
* ISO speed ratings感光度
* ExifVersionExif版本
* DateTimeOriginal创建时间
* DateTimeDigitized数字化时间
* ComponentsConfiguration图像构造（多指色彩组合方案）
* CompressedBitsPerPixel(BPP)压缩时每像素色彩位 指压缩程度
* ExposureBiasValue曝光补偿。
* MaxApertureValue最大光圈
* MeteringMode测光方式， 平均式测光、中央重点测光、点测光等。
* Lightsource光源 指白平衡设置
* Flash是否使用闪光灯。
* FocalLength焦距，一般显示镜头物理焦距，有些软件可以定义一个系数，从而显示相当于35mm相机的焦距 MakerNote(User Comment)作者标记、说明、记录
* FlashPixVersionFlashPix版本 （个别机型支持）
* ColorSpace色域、色彩空间
* ExifImageWidth(Pixel X Dimension)图像宽度 指横向像素数
* ExifImageLength(Pixel Y Dimension)图像高度 指纵向像素数
* Interoperability IFD通用性扩展项定义指针 和TIFF文件相关，具体含义不详
* FileSource源文件 Compression压缩比。
