From 726e9274ea95fa46352556d340c5793a8da51fcd Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Wed, 3 May 2023 13:20:27 +0100 Subject: pipeline: ipa: raspberrypi: Refactor and move the Raspberry Pi code Split the Raspberry Pi pipeline handler and IPA source code into common and VC4/BCM2835 specific file structures. For the pipeline handler, the common code files now live in src/libcamera/pipeline/rpi/common/ and the VC4-specific files in src/libcamera/pipeline/rpi/vc4/. For the IPA, the common code files now live in src/ipa/rpi/{cam_helper,controller}/ and the vc4 specific files in src/ipa/rpi/vc4/. With this change, the camera tuning files are now installed under share/libcamera/ipa/rpi/vc4/. To build the pipeline and IPA, the meson configuration options have now changed from "raspberrypi" to "rpi/vc4": meson setup build -Dipas=rpi/vc4 -Dpipelines=rpi/vc4 Signed-off-by: Naushir Patuck Reviewed-by: Jacopo Mondi Reviewed-by: Laurent Pinchart Signed-off-by: Laurent Pinchart --- src/ipa/raspberrypi/controller/rpi/geq.cpp | 89 ------------------------------ 1 file changed, 89 deletions(-) delete mode 100644 src/ipa/raspberrypi/controller/rpi/geq.cpp (limited to 'src/ipa/raspberrypi/controller/rpi/geq.cpp') diff --git a/src/ipa/raspberrypi/controller/rpi/geq.cpp b/src/ipa/raspberrypi/controller/rpi/geq.cpp deleted file mode 100644 index 510870e9..00000000 --- a/src/ipa/raspberrypi/controller/rpi/geq.cpp +++ /dev/null @@ -1,89 +0,0 @@ -/* SPDX-License-Identifier: BSD-2-Clause */ -/* - * Copyright (C) 2019, Raspberry Pi Ltd - * - * geq.cpp - GEQ (green equalisation) control algorithm - */ - -#include - -#include "../device_status.h" -#include "../lux_status.h" -#include "../pwl.h" - -#include "geq.h" - -using namespace RPiController; -using namespace libcamera; - -LOG_DEFINE_CATEGORY(RPiGeq) - -/* - * We use the lux status so that we can apply stronger settings in darkness (if - * necessary). - */ - -#define NAME "rpi.geq" - -Geq::Geq(Controller *controller) - : Algorithm(controller) -{ -} - -char const *Geq::name() const -{ - return NAME; -} - -int Geq::read(const libcamera::YamlObject ¶ms) -{ - config_.offset = params["offset"].get(0); - config_.slope = params["slope"].get(0.0); - if (config_.slope < 0.0 || config_.slope >= 1.0) { - LOG(RPiGeq, Error) << "Bad slope value"; - return -EINVAL; - } - - if (params.contains("strength")) { - int ret = config_.strength.read(params["strength"]); - if (ret) - return ret; - } - - return 0; -} - -void Geq::prepare(Metadata *imageMetadata) -{ - LuxStatus luxStatus = {}; - luxStatus.lux = 400; - if (imageMetadata->get("lux.status", luxStatus)) - LOG(RPiGeq, Warning) << "no lux data found"; - DeviceStatus deviceStatus; - deviceStatus.analogueGain = 1.0; /* in case not found */ - if (imageMetadata->get("device.status", deviceStatus)) - LOG(RPiGeq, Warning) - << "no device metadata - use analogue gain of 1x"; - GeqStatus geqStatus = {}; - double strength = config_.strength.empty() - ? 1.0 - : config_.strength.eval(config_.strength.domain().clip(luxStatus.lux)); - strength *= deviceStatus.analogueGain; - double offset = config_.offset * strength; - double slope = config_.slope * strength; - geqStatus.offset = std::min(65535.0, std::max(0.0, offset)); - geqStatus.slope = std::min(.99999, std::max(0.0, slope)); - LOG(RPiGeq, Debug) - << "offset " << geqStatus.offset << " slope " - << geqStatus.slope << " (analogue gain " - << deviceStatus.analogueGain << " lux " - << luxStatus.lux << ")"; - imageMetadata->set("geq.status", geqStatus); -} - -/* Register algorithm with the system. */ -static Algorithm *create(Controller *controller) -{ - return (Algorithm *)new Geq(controller); -} -static RegisterAlgorithm reg(NAME, &create); -- cgit v1.2.1
