[Elphel-support] combining frames

[Oleg Dzhimiev]

Hi Andreas,

You were getting bad frames because in my scripts I supposed you set the
resolution like on the picture attached and you did it by scaling - the
camvc writes different values to sensors in these 2 cases and I'm using
these values to calculate the combined frame parts - my fault.

So, could you set the resolution like shown on the picture and not in tab 5?

I also put an input box for scaling to 10359_controls - 2 for 1/2, 3 for 1/3
and so on.
Tested my script - it works for scale factor 2 (I need to test other
factors) and also for 1 at different resolutions. Sending you files and
x359.bit - the one you got from the CVS.

The procedure:
1. set phases
2. set trigger
3. set the correct result frame resoluton in camvc
4. in 10359_controls - set scale factor to 2, check combined box if it's not
checked and start.

Do you need binning/averaging also?

Oleg
