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/rpi/controller/camera_mode.h | 59 ++++++++++++++++++++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 src/ipa/rpi/controller/camera_mode.h (limited to 'src/ipa/rpi/controller/camera_mode.h') diff --git a/src/ipa/rpi/controller/camera_mode.h b/src/ipa/rpi/controller/camera_mode.h new file mode 100644 index 00000000..63b11778 --- /dev/null +++ b/src/ipa/rpi/controller/camera_mode.h @@ -0,0 +1,59 @@ +/* SPDX-License-Identifier: BSD-2-Clause */ +/* + * Copyright (C) 2019-2020, Raspberry Pi Ltd + * + * camera_mode.h - description of a particular operating mode of a sensor + */ +#pragma once + +#include + +#include + +/* + * Description of a "camera mode", holding enough information for control + * algorithms to adapt their behaviour to the different modes of the camera, + * including binning, scaling, cropping etc. + */ + +struct CameraMode { + /* bit depth of the raw camera output */ + uint32_t bitdepth; + /* size in pixels of frames in this mode */ + uint16_t width; + uint16_t height; + /* size of full resolution uncropped frame ("sensor frame") */ + uint16_t sensorWidth; + uint16_t sensorHeight; + /* binning factor (1 = no binning, 2 = 2-pixel binning etc.) */ + uint8_t binX; + uint8_t binY; + /* location of top left pixel in the sensor frame */ + uint16_t cropX; + uint16_t cropY; + /* scaling factor (so if uncropped, width*scaleX is sensorWidth) */ + double scaleX; + double scaleY; + /* scaling of the noise compared to the native sensor mode */ + double noiseFactor; + /* minimum and maximum line time and frame durations */ + libcamera::utils::Duration minLineLength; + libcamera::utils::Duration maxLineLength; + libcamera::utils::Duration minFrameDuration; + libcamera::utils::Duration maxFrameDuration; + /* any camera transform *not* reflected already in the camera tuning */ + libcamera::Transform transform; + /* minimum and maximum frame lengths in units of lines */ + uint32_t minFrameLength; + uint32_t maxFrameLength; + /* sensitivity of this mode */ + double sensitivity; + /* pixel clock rate */ + uint64_t pixelRate; + /* Mode specific shutter speed limits */ + libcamera::utils::Duration minShutter; + libcamera::utils::Duration maxShutter; + /* Mode specific analogue gain limits */ + double minAnalogueGain; + double maxAnalogueGain; +}; -- cgit v1.2.1
