FujiFilm Subject Detection

[greybeard]

May 31st FujiFilm announced a new X series camera with enhancements to subject detection.

Based on published samples (using preproduction cameras) they seem to have added head and body detection for humans (currently face, left eye and right eye).

They have also stated that there is detection for Animal/Bird/Automobile/Motorcycle&Bike/Airplane and Train.

Published samples currently only show bird and dog detection - and the reviewers don't actually say how they set up their camera so this is a work in progress:

Tag 0x4201 has the following additions:

7 => 'Body'
8 => 'Head"

15 => 'Animal Face'
16 => 'Animal Head'
17 => 'Animal Left Eye'
18 => 'Animal Right Eye'

19 => 'Bird Body'
20 => 'Bird Head'
21 => 'Bird Left Eye'
22 => 'Bird Right Eye'

Sometimes it confuses animal and human eyes and its difficult to be absolutely sure that 21 and 22 are left and right eye as birds only show one eye in the samples

It may be possible to tell which element has been selected using tags 0x4283 and 0x4284 but the samples are inconsistent

To be continued

Still a work in progress - these are all from the FujiFilm X-H2S:

Tag 0x4201 has the following additions:

7 => 'Body'
8 => 'Head"

11 => 'Motorbike'

12 => 'Body of Car'
13 => 'Front of Car'

14 => 'Animal Body'
15 => 'Animal Face'
16 => 'Animal Head'
17 => 'Animal Left Eye'
18 => 'Animal Right Eye'

19 => 'Bird Body'
20 => 'Bird Head'
21 => 'Bird Left Eye'
22 => 'Bird Right Eye'

23 => 'Aircraft Body'
24 => <Presumably Aircraft - haven't found an example>
25 => 'Aircraft Cockpit'

26 => 'Train Front'
27 => 'Train Cockpit'

Very interesting!!  Are you able to share some samples?

I was planning to put together a complete set - in the meantime DPR are always good at posting SOOC files during reviews and previews

If you look at the X-H2S preview and search for images with dogs and birds you will see examples:

There are a number of other tags that seem to have useful information about which of the detected objects is actually selected but they are inconsistent and I can't figure them out

0x4280, 0x4281, 0x4283 and 0x4284

minor changes for Tag 0x4201 :

7 => 'Body'
8 => 'Head"

11 => 'Bike' #(Note this is for both motorbike and bicycle)

12 => 'Body of Car'
13 => 'Front of Car'

14 => 'Animal Body'
15 => 'Animal Head'
16 => 'Animal Face'
17 => 'Animal Left Eye'
18 => 'Animal Right Eye'

19 => 'Bird Body'
20 => 'Bird Head'
21 => 'Bird Left Eye'
22 => 'Bird Right Eye'

23 => 'Aircraft Body'
24 => <Presumably Aircraft - haven't found an example>
25 => 'Aircraft Cockpit'

26 => 'Train Front'
27 => 'Train Cockpit'

Great, thanks!  I'll add these to ExifTool 12.43

So cool!  Bird face recognition with eye detection.  Whoa.

Hey both of you, remember they don't capitalize the second f in Fujifilm.  I make that mistake like all the time still!

Ok, ET reports a different shutter speed for this:

ET reports 1/600 and DPR says 1/640.  Are we rounding?  Or are they totally off?

I've been spelling it FujiFilm in ExifTool for nearly 20 years -- it is too late to change now. 

I don't know why DPR says 1/640 for that image
