From c987946e43fda6ccdc21464243880850e7453a91 Mon Sep 17 00:00:00 2001 From: Andrey Konovalov Date: Tue, 16 Apr 2024 11:13:46 +0200 Subject: libcamera: ipa: Add Soft IPA Define the Soft IPA main and event interfaces, add the Soft IPA implementation. The current src/ipa/meson.build assumes the IPA name to match the pipeline name. For this reason "-Dipas=simple" is used for the Soft IPA module. Auto exposure/gain and AWB implementation by Dennis, Toon and Martti. Auto exposure/gain targets a Mean Sample Value of 2.5 following the MSV calculation algorithm from: https://www.araa.asn.au/acra/acra2007/papers/paper84final.pdf Use CameraSensorHelper to convert the analogue gain code read from the camera sensor into real analogue gain value. In the future this makes it possible to use faster AE/AGC algorithm. Right now the CameraSensorHelper lets us use the full range of analogue gain values. If there is no CameraSensorHelper for the camera sensor in use, a warning log message is printed.
