Hi, I'm writing a driver for a CMOS sensor having the following feature:
the frame average brightness value is given by the weighted average of 16 sections. In other words, the scene is divided into 16 square areas: each area can be weighted differently (from 1 to 4) to achieve the whole scene brightness. How can I set the 16 weights of the sub-windows from userspace? Which controls or ioctl can I use to implement such a function?
