[libcamera-devel] raspberrypi: ipa: Add tuning files for "NOIR" ov5647, imx219, imx477 modules

13341 diff mbox series

"NOIR" modules are ones that have had the IR filters removed but are
otherwise identical. The same tuning can be used as for the regular
version except that the colour calibration supplied to the AWB
algorithm no longer works. Instead we need to switch the algorithm to
its basic "grey world" method.

Users with "NOIR" modules can switch to the matching "xxx_noir.json"
tuning file by using the LIBCAMERA_RPI_TUNING_FILE environment
variable.

Oops, please ignore this one, I forgot to add the changes to the build
file into the commit. Another incoming in just a moment...!
