Talk:Known problems

Just noticed - all MJPEG versions of 333 code (at least from v 6.3.4) skip each other frame, so the actual fps is just 1/2 of that of the sensor. Theora version works fine, I also remember fixing that for the 313 cameras. And so far nobody (including me) noticed that (or at least told me).

I'll work full speed on this issue, it is most likely caused by missing interrupts.

--Andrey.filippov 19:10, 21 November 2005 (CST) Found it, will fix shortly. It was because only 2 extra lines were added to frame to accomodate 18x18tiles for 16x16 MCUs (how it was in 313), not 4 for 20x20 tiles. So compressor was waiting for the last 2 lines that came only with the new frame - too late.

So I'll test the fixed code, but still sensor driver need a complete rebuild - it is too messy by now after many modifications fro new sensors and cameras. So now period calculation is not correct when binning is used (and not all the data is in the Micron datasheet as actually binning works for up to 8, not just 3 as they write. We also need to make a cleaner driver as more sensors aree coming soon - and they will have different controls.

3 pictures just to illustrate known problems of CMOS with binning
