2024-09-27libcamera: software_isp: Update black level only on exposure changesMilan Zamazal
The black level is likely to get updated, if ever, only after exposure or gain changes. Don't compute its possible updates if exposure and gain are unchanged. It's probably not worth trying to implement something more sophisticated. Better to spend the effort on supporting tuning files.

2024-09-27libcamera: software_isp: Move exposure+gain to an algorithm moduleMilan Zamazal
This is the last step to fully convert software ISP to Algorithm-based processing. The newly introduced frameContext.sensor parameters are set, and the updated code moved, before calling Algorithm::process() to have the values up-to-date in stats processing. Resolves software ISP TODO #10.

2024-09-27libcamera: software_isp: Use DelayedControlsMilan Zamazal
Use the standard libcamera mechanism to report the "current" controls rather than delaying updates by counting from the last update. A problem is that with software ISP we cannot be sure about the sensor delay. The original implementation simply skips exposure updates for 2 frames, which should be enough in most cases. After this change, we assume the delay being exactly 2 frames, which may or may not be correct and may work with outdated values if the delay is shorter. According to Kieran, the wrong parts are also wrong on the IPU3/RKISP1/Mali pipelines and only RPi have this correct. We need to fix this, by correctly specifying the gains in the libipa camera sensor helpers. The sooner the better because this change could introduce a risk of increasing oscillations. This patch also prepares moving exposure+gain to an algorithm module where the original delay mechanism would be a (possibly unnecessary) complication. Resolves software ISP TODO #11 + #12.

2024-09-27libcamera: software_isp: Use floating point for color parametersMilan Zamazal
It's more natural to represent color gains as floating point numbers rather than using a particular pixel-related representation. double is used rather than float because it's a more common floating point type in libcamera algorithms. Otherwise there is no obvious reason to select one over the other here. The constructed color tables still use integer representation for efficiency. Black level still uses pixel (integer) values, for consistency with other libcamera parts.

2024-09-27libcamera: software_isp: Move color handling to an algorithm moduleMilan Zamazal
After black level handling has been moved to an algorithm module, white balance and the construction of color tables can be moved to algorithm modules too. This time, the moved code is split between stats processing and parameter construction methods. It is also split to two algorithm modules: - White balance computation. - Gamma table computation and color lookup tables construction. While this applies the color gains computed by the white balance algorithm, it is not directly related to white balance. And we may want to modify the color lookup tables in future according to other parameters than just gamma and white balance gains. Gamma table computation and color lookup tables construction could be split to separate algorithms too. But there is no big need for that now so they are kept together for simplicity. This is the only part of the software ISP algorithms that sets the parameters so emitting setIspParams can be moved to prepare() method. A more natural representation of the gains (and black level) would be floating point numbers. This is not done here in order to minimize changes in code movements. It will be addressed in a followup patch.

2024-09-27libcamera: software_isp: Move black level to an algorithm moduleMilan Zamazal
The black level determination, already present as a separate class, can be moved to the prepared Algorithm processing structure. It is the first of the current software ISP algorithms that is called in the stats processing sequence, which means it is also the first one that should be moved to the new structure. Stats processing starts with calling Algorithm-based processing so the call order of the algorithms is retained. Movement of this algorithm is relatively straightforward because all it does is processing stats. The comment about getting black level from the tuning files is dropped. The black level will be taken from CameraSensorHelper if available and that will be implemented in one of the followup patches. Black level is now recomputed on each stats processing. In a future patch, after DelayedControls are used, this will be changed to recompute the black level only after exposure/gain changes. The black level depends on the sensor used, the computed value can be reused in a followup capture sessions with the same sensor. Thus it is sufficient to (re)set the initial value in BlackLevel::init.

This patch adds frame and bufferId arguments to stats related calls. Although the parameters are currently unused, because frame ids are not tracked and used and the stats buffer is passed around directly rather than being referred by its id, they bring the internal APIs closer to their counterparts in hardware pipelines. It serves as a preparation for followup patches that will introduce: - Frame number tracking in order to switch to DelayedControls (software ISP TODO #11 + #12). - A ring buffer for stats in order to improve passing the stats (software ISP TODO #2). Frame and buffer ids are unrelated for the given purposes but since they are passed together at the same places, the change is implemented as a single patch rather than two, basically the same, patches.

Software ISP image processing algorithms are currently defined in a simplified way, different from other libcamera pipelines. This is not good for several reasons: - It makes the software ISP code harder to understand due to its different structuring. - Adding more algorithms may make the code harder to understand generally. - Mass libcamera code changes may not be easily applicable to software ISP. - Algorithm sharing with other pipelines is not easily possible. This patch introduces basic software ISP IPA skeletons structured similarly to the other pipelines. The newly added files are currently not used or compiled and the general skeleton structures don't contain anything particular.

2024-07-31libcamera: Avoid variable-length arraysLaurent Pinchart
Unlike in C where they have been standardized since C99, variable-length arrays in C++ are an extension supported by gcc and clang. Clang started warning about this with -Wall in version 18: src/libcamera/ipc_unixsocket.cpp:250:11: error: variable length arrays in C++ are a Clang extension [-Werror,-Wvla-cxx-extension] 250 | char buf[CMSG_SPACE(num * sizeof(uint32_t))]; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ One simple option is to disable the warning. However, usage of VLAs in C++ is discouraged by some, usually due to security reasons, based on the rationale that developers are often unaware of unintentional use of VLAs and how they may affect the security of the code when the array size is not properly validated. This rationale may sound dubious, as the most commonly proposed fix is to replace VLAs with vectors (or just arrays dynamically allocated with new() wrapped in unique pointers), without adding any size validation. This will not produce much better results. However, keeping the VLA warning and converting the code to dynamic allocation may still be slightly better, as it can prompt developers to notice VLAs and check if size validation is required. For these reasons, convert all VLAs to std::vector. Most of the VLAs don't need extra size validation, as the size is bound through different constraints (e.g. image width for line buffers). An arguable exception may be the buffers in IPCUnixSocket::sendData() and IPCUnixSocket::recvData() as the number of fds is not bound-checked locally, but we will run out of file descriptors before we could overflow the buffer size calculation.

2024-07-24ipa: rkisp1: awb: Unconditionally fill metadataStefan Klug
When the colour temperature estimation gets skipped, the metadata isn't populated. Fix that by filling the metadata early in the function.

2024-07-24ipa rkisp1: Remove temperatureK from FrameContextStefan Klug
The frame context is used to store data used for processing that frame. It is later used to either act as input for other algorithms or to fill the metadata. For the colour temperature this is not needed, as the meatadata shall not contain the value that was active when the image was processed, but the value that was calculated based on the statistics for that image. This is no functional change.
