From 375a70d43eaa30e0c4f59f3da209a0f9fdf2b889 Mon Sep 17 00:00:00 2001 From: David Plowman Date: Thu, 27 Oct 2022 12:39:56 +0100 Subject: ipa: raspberrypi: awb: Update colour temperature whenever manual gains change Previously we only did this when the system starts (on the first switch_mode). Now we do it whenever the manual colour gains are updated. To facilitate this, this R/B vs. colour temperature inverse functions are stored persistently in the AwbConfig.
