Yeah, we have it setup in our code to sync when you call snapshot to the shutter exposure. So, you can totally control this in code.

As for the delay... Please read the MT9V034 datasheet.

en!Thanks a lot! I still want to know can our code can be triggered by the MT9V034's EXPOSURE pin? I want to contronl MT9V034 take a picture by other
circuit through MT9V034's EXPOSURE pin!

The camera, when you call snapshot (), will trigger the exposure pin. If you'd like to snapshot from an external circuit you can use the pyb module to read an I/O pin to trigger off of that.
