Documentation for Apple ithmb format?

I am looking for the ithmb format documentation used by Apple for photos stored on an Apple iPod. I would be happy with the source code or description. The only "documentation" I can find is pre-compiled executables that crack JPEG files.

Does anyone know how to do this?

According to the FileJuicer developers (who can do this conversion on Mac),

The ithmb files are compressed using 16 bits per pixel in the YUV format for TV and are therefore slightly smaller than the converted TIFF files.

It looks like the ithmb format varies from device to device (iPod Photo, iPhone, etc.), so you probably have to manipulate things based on which device the file appeared on.
