-- Eyemodule 2 photos distorting when synced (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=12031)

Well, this is odd:

I've been playing around with my Eyemodule2 for about 3 days now. I like it. A lot.

There's a slight problem, however: a couple photos have distortion at the bottom when they're put on the pc.

I've tried deleting them from the pc, then resyncing (with backup enabled, of course), but they still are distorted.

I downloaded eyeMail to try and mail them to myself as attachements, but that doesn't even recognize the photos... must be meant for the first eyemodule or something...

What else can I try? Normally I wouldn't care that much, but one of the key elements in this photo is in the very bottom of it.

Thanks.

Syncing visor -> PC, then using eyedrop back to Visor retains the distortion, however. It seems almost like those couple photos are being distorted in the conduit or something.

I'm using a Visor Prism, btw.

Ok, one more update ... there's a couple pictures like that, so I tried this one one that I don't care about: converting from full size to palm size and then transferring to PC removes the distortion, although at a smaller size, of course.

New photos I take transfer to the desktop without any distortion.

What did I do here?

Could you tell if the photos were distorted on the PDA?

Distortion!

I'm not sure if this is the same problem, but one of the images submitted to the online gallery I set up is definitely... strange. I'd definitely like to hear if other EM2 users have seen similar oddities.

Looks like you have a poltergeist living in your E2

Pictures seeem to be much better than with EM1.

This is a reproducible...feature

I've taken a bunch of shots with my eyemod2 and a few times when I felt that my hand was shaking or moving too much, it still came out clear on the visor. However, when synced back to the desktop, they come out blurred. If you have the inclination, you can test this yourself: just take several similar shots, first keeping your hand very steady, then slowly increasing the movement/shaking for each consecutive shot. When you compare the images on the visor to those on the desktop, you will see that more of the 'moderately shaky' pictures come out clear on the visor than on the desktop. If you are careful to keep your hand from moving when you take the picture, they always (at least for me) come out clear on the desktop.

Now the real question is why this is happening. After all, if you can view the image clearly on the visor, why not on the desktop? Is the eyemod2 viewer sw on the visor using different data (or a different part of the data) than the conduit uses to create the images on the desktop? Is the conduit corrupting the images? The weird thing is that is *seems* only those photos taken in a 'slightly shaky' way show up distorted on the desktop - how does this information get saved if it's not noticable on the visor?

The only workaround I can think of (until IDEO releases a patch or something) is to use some kind of screen capture application to save the image -- of course, this limits you to palm-sized pics, but it's better than a big, high-resolution blur.

It's caused by scaling ...

The images look good on the Visor because of the scaling that takes place. Scale the image to 160x120 and it will look the same as it does on the Visor.

Your software probably averages the pixels to do the scaling, if just dropped the extra pixels you would see the improvement.

From the eyemodule2 FAQ on the website:
"Hold the eyemodule2 and Visor as still as possible while taking pictures. Wait until
the camera beeps (signally that it has finished capturing the image) before you
move. The image on the handheld may be slightly different than the image on your
desktop due to a small delay between the preview image and the JPEG image, so it
is very important that you hold the camera steady until the image is fully saved.

Take pictures in brighter lighting. Pictures in very low light may have more �noise�,
and since the shutter speed is longer in low light, it is harder to hold the camera
steady for the full exposure. "

This may be what is happening--some of those pictures looked like they had motion artifacts.

After a week with my Eyemodule 2, I must say that not only must you hold the camera *very* still, your subject must be *very* still as well. Hard to get a 3 year-old and a 2 year-old to sit still so you can take a shot with your eyemodule!

Anyway, I will not take it back, though...it's just too convenient. And when the lighting and surroundings are right, the shots look great on the visor and good enough on the desktop to make this a true keeper.

No no no no no

Some interesting ideas, and I'm glad to get some input, however:

When I shrink the image from full size to palm size on the Visor, then sync, the image is undistorted. (However, it is very small

It's not just that the distortion isn't visible on the Visor, the bottom of the picture actually looks... twisted is the best way I can put it. It's NOT a motion blur. (I've also taken pictures where the object was moving or my hand was moving, so I know what that looks like).

The thing that really really kills me is the bit that if I downsize the image it comes out clear on the pc. I don't get that at all.

JPEG different than Preview

I can confirm that the EM2 does take 2 different pictures when you are in full res mode. The preview that you instantly see on the Visor and the JPEG that syncs to the desktop are exposed about a half second apart! This makes it impossible to judge the picture you took because you can't see the real thing on the Visor. I took some shots of my friends at work today while they mugged for the camera and the shots I synced tonight have totally different expressions, some even have hands over their faces that didn't show up on the Visor. Huge bummer!
When I tried "downsizing" a full res picture to palm size, it still has the expression from the preview. This tells me that the thing is not downsizing at all, just throwing away the full size JPEG that it has no ability to show you on Visor.

I love the EM2, and have been getting really good results with carefull attention to lighting, but I hope there will be a firmware update to let us see the JPEGs on the Visor.

Andy

Well, in a word, 'crap.'

I was just about to ask if maybe it just ditched the full size when downsizing, and you came along and confirmed my suspicion.

Oh well. I guess I just need an image editor with good filters for making the 160xwhatever image look good when I blow it up.

Thanks for the hinkfo.

I've been using an Eyemodule2 for a couple of days now and haven't seen any distortion of photo's after synching. But, I'm on a Mac platform. Could this be something associated to PC's?
