From dbcf4d82473936ce1cfaac0613fba99fb592c957 Mon Sep 17 00:00:00 2001 From: David Plowman Date: Tue, 8 Dec 2020 20:44:38 +0000 Subject: ipa: raspberrypi: awb: Add GetConvergenceFrames method to AWB base class We add a GetConvergenceFrames method to the AwbAlgorithm class which can be called when the AWB is started from scratch. It suggests how many frames should be dropped before displaying any (while the AWB converges). The Raspberry Pi specific implementation makes this customisable from the tuning file.
