2024-04-16libcamera: ipa: Add Soft IPAAndrey Konovalov
Define the Soft IPA main and event interfaces, add the Soft IPA implementation. The current src/ipa/meson.build assumes the IPA name to match the pipeline name. For this reason "-Dipas=simple" is used for the Soft IPA module. Auto exposure/gain and AWB implementation by Dennis, Toon and Martti. Auto exposure/gain targets a Mean Sample Value of 2.5 following the MSV calculation algorithm from: https://www.araa.asn.au/acra/acra2007/papers/paper84final.pdf Use CameraSensorHelper to convert the analogue gain code read from the camera sensor into real analogue gain value. In the future this makes it possible to use faster AE/AGC algorithm. Right now the CameraSensorHelper lets us use the full range of analogue gain values. If there is no CameraSensorHelper for the camera sensor in use, a warning log message is printed.

2024-04-16libcamera: software_isp: Add DebayerCpu classHans de Goede
Add CPU based debayering implementation. This initial implementation only supports debayering packed 10 bits per pixel bayer data in the 4 standard bayer orders.

2024-04-16libcamera: software_isp: Add Debayer base classHans de Goede
Add a base class for debayer implementations. This is intended to be suitable for both GPU (or otherwise) accelerated debayer implementations as well as CPU based debayering.

2024-04-16libcamera: software_isp: Add SwStatsCpu classHans de Goede
Add a CPU based SwStats implementation for SoftwareISP / SoftIPA use. This implementation offers a configure function + functions to gather statistics on a line by line basis. This allows CPU based software debayering to call into interleave debayering and statistics gathering on a line by line basis while the input data is still hot in the cache. This implementation also allows specifying a window over which to gather statistics instead of processing the whole frame. Doxygen documentation by Dennis Bonke.
