2024-06-11ipa: rkisp1: Add GammaOutCorrection algorithmStefan Klug
Add a gamma algorithm for the rkisp1. It defaults to a gamma of 2.2 which closely resembles sRGB. No seperate sRGB mode was implemented because the pwl that models the gamma curve is so coarse that there is basically no difference between srgb and gamma=2.2. The default can be overridden within the tuning file or set at runtime using the gamma control. The gamma algorithm is not enabled by default. This will be done in future tuning file updates.

2022-08-21ipa: rkisp1: Add support of Denoise Pre-Filter controlFlorian Sylvestre
The denoise pre-filter algorithm is a bilateral filter which combines a range filter and a domain filter. The denoise pre-filter is applied before demosaicing.

2022-07-28ipa: rkisp1: Add support of Filter controlFlorian Sylvestre
Denoise and Sharpness filters will be applied by RkISP1 during the demosaicing step. The denoise filter is responsible for removing noise from the image, while the sharpness filter will enhance its acutance. Add filter algorithm with denoise and sharpness values based on user controls.

The Defect Pixel Cluster Correction algorithm is responsible to minimize the impact of defective pixels. The on-the-fly method is actually used, based on coefficient provided by the tuning file.

The Lens Shading Correction algorithm applies multipliers to all pixels to compensate for the lens shading effect. The coefficients are specified in a downscaled table in the YAML tuning file.

2022-03-28ipa: rkisp1: Introduce AWBJean-Michel Hautbois
The RkISP1 ISP calculates a mean value for Y, Cr and Cb at each frame. There is a RGB mode which could theoretically give us the values for R, G and B directly, but it seems to be failing right now. Convert those values into R, G and B and estimate the gain to apply in a grey world.

2022-03-28ipa: rkisp1: Introduce Black Level CorrectionJean-Michel Hautbois
In order to have the proper pixel levels, apply a fixed black level correction, based on the imx219 tuning file in RPi. The value is 4096 on 16 bits, and the pipeline for RkISP1 is on 12 bits, scale it.

2021-11-29ipa: rkisp1: Introduce AGCJean-Michel Hautbois
Now that we have IPAContext and Algorithm, we can implement a simple AGC based on the IPU3 one. It is very similar, except that there is no histogram used for an inter quantile mean. The RkISP1 is returning a 5x5 array (for V10) of luminance means. Estimating the relative luminance is thus a simple mean of all the blocks already calculated by the ISP.
