示例1: i
// readName will read the make and model of the image.
//
// If the name is read, it will return true, and the make/model
// will be available in camera_make/camera_model members.

if (camera_make.length() != 0 && camera_model.length() != 0) {

// See if we can find EXIF info and grab the name from there.
// This is needed for Sigma DP2 Quattro and possibly later cameras.
