There are some third party tools that can do this. I think there's a Perl script and a Python script that can extract the contents of the eyemodule .pdb files into image files.

Okay, buds -- the "real" stats.
Why is "real" in quotes? ... because I'm not 100% sure.
The GOOD NEWS is I was "wrong" about the FULL SIZE EM2 images being 130k ... it looks like they're ONLY 115K!!!
Hip, hip, hooray!
But ... where am I getting this data?
P.15 of the on-line .PDF file at EM2.COM.
You can see the little specs in the little screenshot.
The "bad news" (in quotes because I'm not 100% sure; hey, it takes a lot to be johnny-on-the-spot, eh?) is if you check the rest of the site (esp. the SAMPLES page), many seem a whole lot larger (like 200k, or something -- but, hey, that's only 13k more than EM1's "full-sized" crappy-snappies, eh?), so ... because I'm not 100% sure.
Well, y'know what I mean.

But another good tid-bit of "because I'm not 100% sure" verification is on the following page (the real specs page) ... it looks pretty rock-steady & absolute that the EM2 is using 16 SCALES OF GRAY, no matter what Visor model it's plugged into.
Maybe I'm just "reading what I want into it," so feel free to check it yourself.
But, man, I really can't see myself NOT buying this module at this point ... it's only a matter of time ...
(What time does CompUSA open up today, eh?)
Hope this was useful.
(Eh ... because I'm not 100% sure, y'know.)

Outrageous file size for movies

Excuse me, before you bash something know what you are talking about. If you bothered to download those movies and checked their info out you would see that they weren't compressed at all. Quicktime can use a variety of codecs, but the movies posted on the site did not use any compression. I assume this was to show people exactly how the movies would look once transferred to your computer.

After the transfer you can compress them any way you like. You could even make them into MPEG movies if that's what floats your boat, however, MPEG movies are not easy to convert into other formats which is presumably why the E2 does not use it as its native format.

From the mind of CJ Miller ...

"Apple quicktime is, in my mind a TERRIBLE compression format to use. Come on people, investigate the technology before you release a product that uses crappy compression."

Apple QuickTime is not a compression format, it is an open media framework supporting hundreds of codecs including mpeg, sorenson, and others designed for small file sizes. Unlike other media players, It also supports full bandwidth uncompressed files, for applications where preserving the original pixels is more important than file size. QuickTime is absolutely the most flexible, feature rich, and powerful authoring format available.

I opened one of the movies from the Eyemodule gallery in QuickTime Player and compressed it using the sorenson codec that is included for free with QuickTime. The file went from 3.5 mg to 300 K with a barely noticeable visual change. Then I made another version choosing a lower data rate and resulting in a file of 100 K with slightly more obvious compression artifacts. The important point here is that I chose whatever tradeoff between file size and visual quality that I want.

QuickTime is one of the key reasons I'm going to buy the Eyemodule2, as I don't want the camera making the compression choices for me.

Come on CJ, investigate the technology before you release any more pearls of wisdom that use crappy information.

Once again, you are wrong. The movies stored on the Visor are in a different (probably proprietary) format which are then converted to "raw" video during a hotsync. Going back in this thread you will notice that a 5 sec clip takes up only 1.1 MB of Visor memory. This is roughly 1/3 of the size of the uncompressed files. Even if the E2 converted the Visor files to MPEG on hotsync, they would still take up 1.1 MB of Visor memory.

You're right, maybe next time I'll refrain from talking about Apple technology, considering there isn't much to talk about. Maybe someday that company will get ahead, without help from Microsoft.

Yawn, an Apple v. Windoze flame war. Been there, done that. Actually, finding out that Eyemodule 2 uses QuickTime has bumped this from "Really Neat" to "OMG!, Me Want!!!!" status. The possibilities of Quicktime are endless, and combine that with the multimedia/movie capabilities built into EVERY new Mac makes for infinite ways to combine the images from an Eyemodule. And as for tech, I propose a test. I'll make a movie using the free movie creation software a Mac comes with and you make one with the free movie creation software your WIntel box comes with. Oh, wait.

Does anyone know if it's possible to use the EM as a webcam when pluged in the craddle ?
Would it even be possible ?

quicktime

in my experience quicktime & mpeg encoded movies of similar resolution, etc. are similar in resultant file size.


As an added note, however, quicktime clips seem to be of higher video quality than those produced by other encoding systems/codecs.

Cool Idea! The USB port should easily be able to handle the 640x480 stream going through it. Now we only need to have somebody come out with the pseudo conduit and drivers (that's the hard part)

I got my Eyemodule2 this weekend and posted some pictures (courtesy of iTools - this has to be the easiest way to make an album). The url is:
