How to manage weighted sections for scene brightness calculation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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?

Thank you for the support,
Davide
