From a0734f72d4deca4a3f1d99122e8a7071e031c5de Mon Sep 17 00:00:00 2001 From: Jean-Michel Hautbois Date: Fri, 5 Nov 2021 18:56:57 +0100 Subject: ipa: ipu3: awb: Add support for color temperature The AWB estimates the color temperature, but it is not used at all. It can be useful for debug purpose at least, but also for lux estimation later, to be able to know the temperature estimated for a given frame. Add a new member to the IPAFrameContext::awb for this purpose, and update the value in AWB.
