Cesar, AVT say its 2/3" cmos global shutter, 1280x1024, 6,7 um x 6,7 um cell size, raw8 at full res 25fps only...

My bad Igor, you are right...I actually have one F-131c at home!..The F-131 is only capable of shooting 25 fps at FULL resolution, but if you go 1280x720 or 720p in other word, you are able to reach 30p easily.The F-131 has a 10 bit interface.. I will get to you about that later.

Thanks,
Cesar Rubio.

BTW, Just curious, while the Sumix and assoicated Micron sensor is a good camera, has anyone taken a look at the Kodak CCD cameras?

For instance, the Pulnix or the Imperx cameras using the KAI-4021 4Mpix CCD?

I'm not sure on the pricing, but they are native gig-e cameras using the Pleora gige-link libraries.

Because they are IT CCD's, they are global shuttering, so no problems with rolling shutter like you get on the CMOS chips . . . it's also a fairly large sensor (16mm x 16mm).

Additionally the Imperx camera has the ability to-do in-camera flat field correction and black-frame correction.

Just some thoughts . . . I'm sure they're quite a bit more expensive than the Sumix, but they do look very good. You can see some image samples from the KAI-4021 here:

While the Illunis cameras look interesting, there seems to be some issues with tap matching that I can see in their images, which will give you the infamous "split-screen" effect that we've see with the JVC camera (early models). Imperx with their on-camera flat field correction supposedly solves the issues with any split-screen (tap-mismatching) effects. I guess if someone was interested, they could talk to Illunis and see what the issues might be with tap-mistmatch effects. One thing to keep in mind though is that the Illunis is not a gigabit ethernet camera.

Here's the link to the Imperx:

Allied has their Pike F-421B camera that also uses the Kodak CCD and uses firewire 800:

One warning with any CCD camera system that is multi-tap, especially in the high-speed arena, you want to make sure they they adaquately handle tap mismatching in regards to gain offsets (so offsets that occur because of differing signal gains on the two ADC's when signal is added, rather than offsets that are basic DC-level offsets which can be subtracted out), or else you're going to end up with a split-screen effect.

In CMOS cameras, ACD mismatching effects and gain offsets present themselves as column-to-column variations . . . on good CMOS chips, only a subtraction is needed since there's only a pure DC offset between the ADC's . . . on other CMOS chips a second gain correction (flat fielding) is necessary since the ADC's exhibit a gain offset as you add signal. Fill Factory's CMOS chips are notorious for requiring a two-point correction. Micron on the other-hand has a very good process and on-chip correction, so they're actually able to handle these issues on the chip itself, or at the very least an easy black subtraction is all that's necessary to correct any column-to-column offset issues.

Hope this helps,

Jason

Thats what I ment all the way (1280x720 raw8/10 25/30p)...Id like to see some footage. Can you do something like 720x576 50/60p?

Jason, Pike F-421B is about EUR 4990. Way to heavy, but good to know stuff about CCD/CMOS.

BTW, While the color reproduction is not too great (and they're a bit noisy as well), Fill Factory's (now Cypress) IBIS-5A sensors do provide a global shutter to prevent any rolling shutter artifacts, and you can get cameras based on that sensor for a bit cheaper as well . . . in fact I believe that Sumix makes a camera using the IBIS-5A, but again, it's downside is that it's not a very pretty chip (not as pretty as the Micron). Also like other Fill Factory sensors, I think it needs a 2-point correction (so both gain and offset) in order to look it's best.

I'm definitely interested in software for the M73 since I still have one myself. It's been collecting dust since I havent had time to work with it at all. Are you currently working on this software? Keep the updates coming.

Noah -- great to see you here again! Rob's software promises some very useful extra duration with RAM buffering (instead of just RAM recording). Did you come to any conclusions RE your column-skipping anamorphic experiments?

Yes and no. I have been distracted by other things over the last month or so; but yes, I am still actively pursuing the project.
