Difference between REQUEST_TAKE_PHOTO and REQUEST_IMAGE_CAPTURE

I read the developer docs on how to use existing Camera software on the device to take a picture and return to the app here and I was confused by the fact that when simply grabbing a thumbnail, they use the following intent code

startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);

however, when taking a picture and saving the full file, they use:

startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);

At least for me, REQUEST_TAKE_PHOTO can not be resolved, and I cant find any reference to it anywhere. Anyone know what the differences are between the two?
