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/cam_helper_imx296.cpp | 83 ------------------------------- 1 file changed, 83 deletions(-) delete mode 100644 src/ipa/raspberrypi/cam_helper_imx296.cpp (limited to 'src/ipa/raspberrypi/cam_helper_imx296.cpp') diff --git a/src/ipa/raspberrypi/cam_helper_imx296.cpp b/src/ipa/raspberrypi/cam_helper_imx296.cpp deleted file mode 100644 index ecb845e7..00000000 --- a/src/ipa/raspberrypi/cam_helper_imx296.cpp +++ /dev/null @@ -1,83 +0,0 @@ -/* SPDX-License-Identifier: BSD-2-Clause */ -/* - * Copyright (C) 2020, Raspberry Pi Ltd - * - * cam_helper_imx296.cpp - Camera helper for IMX296 sensor - */ - -#include -#include -#include - -#include "cam_helper.h" - -using namespace RPiController; -using libcamera::utils::Duration; -using namespace std::literals::chrono_literals; - -class CamHelperImx296 : public CamHelper -{ -public: - CamHelperImx296(); - uint32_t gainCode(double gain) const override; - double gain(uint32_t gainCode) const override; - uint32_t exposureLines(const Duration exposure, const Duration lineLength) const override; - Duration exposure(uint32_t exposureLines, const Duration lineLength) const override; - void getDelays(int &exposureDelay, int &gainDelay, - int &vblankDelay, int &hblankDelay) const override; - -private: - static constexpr uint32_t minExposureLines = 1; - static constexpr uint32_t maxGainCode = 239; - static constexpr Duration timePerLine = 550.0 / 37.125e6 * 1.0s; - - /* - * Smallest difference between the frame length and integration time, - * in units of lines. - */ - static constexpr int frameIntegrationDiff = 4; -}; - -CamHelperImx296::CamHelperImx296() - : CamHelper(nullptr, frameIntegrationDiff) -{ -} - -uint32_t CamHelperImx296::gainCode(double gain) const -{ - uint32_t code = 20 * std::log10(gain) * 10; - return std::min(code, maxGainCode); -} - -double CamHelperImx296::gain(uint32_t gainCode) const -{ - return std::pow(10.0, gainCode / 200.0); -} - -uint32_t CamHelperImx296::exposureLines(const Duration exposure, - [[maybe_unused]] const Duration lineLength) const -{ - return std::max(minExposureLines, (exposure - 14.26us) / timePerLine); -} - -Duration CamHelperImx296::exposure(uint32_t exposureLines, - [[maybe_unused]] const Duration lineLength) const -{ - return std::max(minExposureLines, exposureLines) * timePerLine + 14.26us; -} - -void CamHelperImx296::getDelays(int &exposureDelay, int &gainDelay, - int &vblankDelay, int &hblankDelay) const -{ - exposureDelay = 2; - gainDelay = 2; - vblankDelay = 2; - hblankDelay = 2; -} - -static CamHelper *create() -{ - return new CamHelperImx296(); -} - -static RegisterCamHelper reg("imx296", &create); -- cgit v1.2.1
