glad to hear the altasense should work.. so is the filter optical or is it a chip??

btw, obin.. any chance of you having a 'do-it-yourself' guide for building your camera similar to the micro-35 deal..?? my hope is to still be able to use alot of your insights to construct something alittle cheaper on my own..

thanks and keep up the good fight.

Obin, can you suggest, how can anybody get a single 3562?

A do-it-your-self guide for a FPGA hardware camera? I don't think so!
that is like asking for a do it your self panasonic varicam system...LOL

if you want a chip all you need to do is order one from any of the chip makers..not hard at all..the altasense chip with nothing to work with it but a serial port is $1500

Thread re-opened (and the other Obin thread has been merged into this one).

I had to remove a lot of garbage from a couple of people. In order to avoid problems in the future, please take note. These are not suggestions -- these are RULES:

1. Do not hijack threads. If you want to talk about something else, then start a new thread.

2. No personal attacks. If you have an issue someone, just use the "Ignore This User" feature in your Controls link on the nav bar at the top. You'll never hear from them again.

3. No personal attacks. No flaming.

4. No flaming. No personal attacks. Get it?

5. If you spot an offensive post that you perceive to be a personal attack or a flame against you, DO NOT RESPOND TO IT. Rather, use the "Report This Post" function. I'll come in and remove the offensive material. If you do respond, then you're part of the problem. I'll boot you as well as the other guy. There is NO JUSTIFICATION HERE for escalating a flame war. We don't do flame wars at DV Info Net. That's what makes us different from other message boards.

6. Re-read steps 1 through 5. Thanks,

every camera has an optical IR cut filter for outdoor sunlight. Altasense is the same, we must buy one and mount it on the cmos

can anyone here help me understand this chart?

it's for the ALtasense color separation

anyone see any reason from this image (other then it's a lin-bayer filter) not to use this chip? I am about to buy one!

does anyone have a good bayer algorithm to apply on it?

What was the original resolution of that TIF?

1920 x 1080 with bayer filter is the orginal resolution (procam 3562 has active a little more than 1920x1080, but the few extra pixels would likely be cropped).

There's alot of jaggy edges on that image. It appears it was a lower res then resized larger with a bad resizer.

More likely because of the simple debayer algorithim used. Simple debayer can cause colour fringing and all sorts of artifacts between high contrasting areas.

I did not know that the color artifacts are from the de-Bayer..I was thinking it was a lens issue ;)

Keith did you happen to pickup and bookmark any of the links for high quality bayer algorithms in this thread? I can't seem to find them when I search...

we will need to try one of them when we can..

So of the colour fringing between high contrast is easily attributed to bad debay. That looks to be the case for that because the fringing isn't as uniform as it would be as a lens issue, but it is hard to tell.

And unfortunately i never did bookmark any of the debayer.

Obin,
Congratulations and good luck with the new incarnation of your project. Way to go...
Have a loook at this CL script (dcraw) for Linux to convert RAW images from digital stills cameras by Dave Coffin, or look at this page to get more info. Could be a starting point.
