Don't know, could be that there is a feature in the camera measuring the
lightning condition and is setting the exposure length thereafter.

No sorry, hard to tell without any datasheets.

Read this document:
http://m560x-driver.wiki.sourceforge.net/m5602-FAQ
If you want to play around, check out m5602_s5k83a.h and start to play with
the init sequence in order to identify what any specific register addresses
does.
