What is Motorola Camera app's Photo naming convention?

Question

The Images are saved as IMG_yyyyMMdd_kkmmssSSS.jpg

Here, the yyyyMMdd part in filenames matches the first half of the photo's EXIFDate/Time data.

Can anyone please help me out with figuring out the rest of the file name and how can I extract this from the photo's EXIF data?

Just curious, where did you get the info about the filename format? — Andrew T., Commented Jul 3, 2016 at 14:37

The format follows the pattern used in DateFormat class from Java/Android. It's:

IMG: constant prefix for Images
yyyyMMdd: date
- years (4-digit)
- months (2-digit)
- days (2-digit)
kkmmssSSS: time
- hours (2-digit in 24-hour format, from 1-24)
- minutes (2-digit)
- seconds (2-digit)
- milliseconds (3-digit)

Thanks for your swift reply. However I have already figured this out. The app uses the SimpleDateFormat class in Java. What I still don't know is that how the values for kkmmssSSS is determined and additionally if it can be found in the photo's EXIF data. I am guessing that it denotes the Date/Time Orignal tag under EXIF. Would be nice if you or anyone else could confirm.

I wouldn't know if you hadn't mentioned it in the question. Could you put some example filenames on the question? As for EXIF, I'm afraid I can't help with that since I don't have (photos from) Motorola devices.
