CMOSIS 600fps VGA Sensor Presentation

CMOSIS Vision 2011 presentation video talks about CMV300 fast VGA sensor:

  1. The noise is quite high (20e-) compared to the other 8T pixel architectures they showed earlier...why?

  2. If it runs fast then the whole camera gets probably hot and if its very hot it has high dark current. I can't see for which T that 20e is measured. And also if you want 600 FPS then at max 1/600 sec exposure which won't catch much of it.

  3. VGA at 600 fps is not even breathing hard. I don't think things get that hot.

    10 years ago, Photobit MV13 1.3 Mpixels glpobal shutter at 1000 fps there no not a "not camera" issue and I am sure now things are quite improved.

  4. MV13 is on my mind because I just found out that that chip is still being used in products being manufactured today. It still has a Photobit logo on it. Strange, for a company that was swallowed up 10+ years ago! Credit goes to Alex Krymski who was the lead designer of that part.

  5. @EF isn't MV13 ~500 FPS full frame?

  6. Yes, but MV13HS (I think that was the name) ran at 1000 fps. Actually, many of the MV13s would run at 1000 FPS but Alex and his team made a few tweaks for MV13HS so we could spec that performance. It is interesting that niche market products have such a longer life than consumer-grade sensor products. Not surprising but still interesting to see it happen.

  7. 8Mp@30fps (fairly common now) is equivalent to VGA@800fps. With all due respect, other than choosing to implement GS, this isn't especially groundbreaking.

  8. One does not need to have a ground-breaking technology necessarily. The part seems to combine a nice set of specs, is very compact and what I heard priced well. For many low res MV camera's, this sensor would be a good pick over some larger and more expensive CCD's.
