Camera: problem with face detection

[Guest SatanClaus]

Hi everyone  :)

I'm using a modified version of the camera executable, I donwloaded it from here but I forgot who modified it  :D it's the version which saves the pictures naming them accordind to the date and time instead of the useless default naming.

I'm having this issue: whenever I try to use the face detection setting, it does not let me take the picture by pressing the button (neither the shutter nor the central one), but it just takes the picture by itself the very moment it detects a face, so I have to rush to center the picture the way I want it (and most of the times I can't make it in time).

Anyone else has the same issue and/or know to to possibly solve it?

Face detection? I think you mean the smile detection setting -- I don't have a "face detection" setting.

And, that's the correct operation of the smile detection mode... It waits until it detects a smile, then it snaps the picture automatically.

This threw me off at first too. So did the panoramic mode -- it does its magic automatically as well, after you snap the first shot. Then, just slowly pan across the area you want to stitch together a panorama from, and it will automatically snap the successive frames when they come onto view, up to 8. If you want too stop earlier, press the shutter (or action) button.

This is all very poorly documented, so it can be very confusing.

Yep, sorry, I meant the smile detection  :D

But I dare to disagree... it's not the normal and correct operation: with the original camera executable it just detect the smile(s) (even more than one) and then it WAITS for me to snap the picture, I triple checked it restoring the original file... 

I can surely live without that function (it's not really useful if I don't have the time to choose the right framing for the picture), but I was curious to know if there was a way to make it work ok with the modified exe (which I will still use no matter what, I highly prefer to have the pictures named according to date and time)  :)

Well, the automatic manner that you describe as a bug is the way the camera on my 910 has always worked, from day one.

Perhaps there's a registry tweak you applied and forgot about that disabled this feature?

Further, I'm hard-pressed to think of any use for a smile-detection feature that, well, really doesn't do anything except draw a box around someone it thinks is smiling.

Anyway, anyone else care to comment on how this functions on their Omnia?

I gotta say that, although I've used the feature very rarely, it was helpful at catching a few people smiling when I tried it out for just that purpose. Especially in sunlight where I couldn't see the screen well enough myself to tell when to snap the pic.

EDIT: Oh, one more thing: Does this version you are using have the GPS feature (saving lat/long with the picture)? This date/naming feature sounds really enticing.

Nope, no registry tweaks, it changed behavior as soon as I replaced the exe file.

The smile detection does not only "draw a rectangle" around the face(s), it actually sets the focus on those areas, the same as if you put the face in the center of the frame, half press the shutter button to focus it, then move your camera while keeping it half pressed in order to change the framing of the picture but _not_ the focus.

The version I'm talking about is 100% the same as the original, the only difference I noticed is this behaviour with the smile detection function, but I can't tell 100% about the gps feature 'cause I never used it

Actually, I'm searching this forum trying to find it again, 'cause I did a hard reset and forgot to backup the exe  :) :P

Gonna put a link in here as soon as I find it again.

Thanks for finding that!

I went back and played with mine again, and must revise my explanation of its operation: It doesn't do its thing on my 910 until "armed" by pressing the shutter button (or action). At that point, it's activated, and will then snap a pic when it detects a smile.

So, it won't just snap a pic all on its own. I have to "arm" it with a shutter press when I'm ready. Then, it doesn't snap a picture when I press the button, but instead waits until it detects a smile, then captures the picture. The whole thing resets, and starts over (waiting for a shutter press).

Is this the way yours is working or is it just snapping pictures all on its own without any button press at all?

The latter... as soon as you set the smile detection on, it looks for a smile and just snaps the picture by itself w/o pressing anything.

The way yours is working is quite correct, I don't really mind if it "locks" the smile(s) before or after pressing the shutter button, as long as I still have the chance to delay pressing it 'til I framed the picture the way I want it :)

I still have to try it again after my hard reset though, maybe it will work the right way, I had a little bunch of "strange behaviours" all around the Omnia lately, so there's a chance it was not the exe fault :D

My i910 which has only been flashed with the official CF03 ROM will take the picture as soon as it detects a smile, without any half or full press of the shutter button to arm it. I thought it was the normal mode of operation, but I'm fine with it either way.
