I need a lot of time for writing English(lol .
I got 2 reply during writing this document. First, I replay to Alex.
Alex, I also think so, when reading a code. But my sony NEX3 is sometime move the AF point to most far/near. But almost good for me. So I think it's not important thing.
For example, I'm sometime use a stabilizer and crane. I can't touch focus ring when the camera on these equipments. It's better than nothing.
And I understood that I need to guesswork on movie_af for searching focus peak.
1% and nanomaid my confusing points under follow:
----
I just reading the original code today.Now I need to understand all of original code.
1: Live view buffre is YUV422 . correct?
2: I don't know how to get contrast from YUV 422 buffer(Y is luma, but we can use this for contrast comparering?)
3: In focus.c , it's using buf

- but not defined . where defined it. I guess it's a Live ViewBuffer.
(buf - is defined anyware, so grep is not working for finding it.)
My understanding for contrast AF.
Most higher contrast = in focus
Is this a correct thing?
Basically, I'm usually writing a TCP/IP code . So I have no experience to write a graphic handling codes.I need more study for understanding graphic handling and algorithms.
P.S. already midnight in my country. Time difference is a little hard to collaborate with international community. Also I'm writting a Japanese FAQ on wiki side. Become a little slow for this activity..
P.S.2 Thank you for reading my poor English.
