As I’m developing a driver for a new imaging sensor, I have been looking at other drivers and see how they implemented all the modes. I successfully implemented 18 modes already, but I can’t seem to understand how to implement Region of Interest functionality.
I’ve been looking around and see that more sensors have a programmable ROI section or even multiple ROI sections like mine does. It allows you to set two coordinates to create a ROI. Unfortunately, it’s a subject I can’t find any information about regarding Video 4 Linux.
I’ve looked up information about sensors with available drivers, but these don’t seem to have any ROI functionality.
How can I implement ROI mode in my driver?
