i have a problem with ADV7188.
Normally i use it with no problem but now i have something new, live brightness - contrast adjustment.
When i put contrast change command inside the init sequence image output becomes very bad. artifacts..
when i put it at the end, image output is good.
when i put brightness control near that command, again artifacts occur.
What is the correct way/sequence for live brightness/contrast adjustment.
do we need a reset signal at the beginning?
do we have to send commands in an order?
do we need any delay between them?
i need your help.
Thanks and Best Regards..
