Add a gamma algorithm for the rkisp1. It defaults to a gamma of 2.2 which closely resembles sRGB.

std::unordered_map::merge(source) has the side effect of actually moving items from source to target. In this case the controls were removed from the source maps on the first call to updateControls() and on the second call to updateControls() they were missing in the source maps and therefore also removed from the camera. Fix this by using insert() instead of merge(). This is most likely cheaper than copy-contructing the source map.

2024-06-02libcamera: software_isp: Move color mappings out of debayeringMilan Zamazal
Constructing the color mapping tables is related to stats rather than debayering, where they are applied. Let's move the corresponding code to stats processing. The same applies to the auxiliary gamma table. As the gamma value is currently fixed and used in a single place, with the temporary exception mentioned below, there is no need to share it anywhere anymore. It's necessary to initialize SoftwareIsp::debayerParams_ to default values. These initial values are used for the first two frames, before they are changed based on determined stats. To avoid sharing the gamma value constant in artificial ways, we use 0.5 directly in the initialization. This all is not a particularly elegant thing to do, such a code belongs conceptually to the similar code in stats processing, but doing better is left for larger refactoring. This is a preliminary step towards building this functionality on top of libipa/algorithm.h, which should follow.

2024-05-16ipa: rpi: Add HDR supportNaushir Patuck
Add support for the following HDR modes in the Raspberry Pi IPA: - Night mode - Single exposure mode - Multi-exposure (merged and unmerged) The algorithm is updated to expect the HDR short channel to meter explicitly for highlights. This means that it will not in general under-expose the short channel more than is actually necessary. When images don't have much saturation, it's good to detect this so that some of the boost we want to apply to the dark areas can be implemented as regular gain. This means we can then adjust the tone curve less, leading to less flat looking images. The impact on the HDR algorithm is then that this determines how we build tonemaps dynamically. The highlights are more-or-less correct now, so we have to build a power-type curve that gives us the appropriately configured targets in the lower part of the histogram. We allow the tuning file to supply the maximum spatial gain value, rather than the whole curve (though it can supply this if it wants). Some parameter defaults are tweaked to be generally better across the range of our cameras.
