[libcamera-devel] [PATCH 4/4] ipa: raspberrypi: Add tuning file for IMX296 sensor

Laurent Pinchart laurent.pinchart at ideasonboard.com
Mon Dec 20 00:27:14 CET 2021


From: Naushir Patuck <naush at raspberrypi.com>

The Sony IMX296 exists in two versions, colour (Bayer) and monochrome.
The tuning file corresponds to the colour version.
