OV13850 AF algorithm

Sheba

Hi Folks,

I wanted to change the speed of AF algorith in OV13850 camera. The current speed (when streaming 1080p-video) is 67 ms between each consective steps by the VCM (8 steps in total form 10 cm to inifinite postion of the VCM). Though, the streaming is 30 fps at this resolution, but the AF fps are half of that (15 fps, 67 ms), which means that there is frame skipping when implementing AF.
I belive to the change the AF speed I have to have access to the code of (libisp_silicomimageisp_api.so) in the following directoryfirefly-rk3288\hardware\rk29\camera\Config.

Could any one help me to confrim the source code of the .so file is avaialbe? or where can I change such AF speed for OV13850, which file I should make the changes?

Your prompt response is highly appreciated.

Hi Sheba, Isle,
I also would like to modify the autofocus algorithm.
I’d like to experiment the assistance of a distance sensor to optimize autofocus.
How can we get the libisp_silicomimageisp_api.so source code ?
