[PATCH 0/3] Fix full range quantization on rkisp1 based devices
From: Stefan Klug
Date: Thu Feb 27 2025 - 06:47:07 EST
Hi all,
After I sent a patch too early yesterday, I'm sending the corrected
version now. This series fixes two issues with the rkisp1 driver and
full range quantization. It was developed and tested on a imx8mp board
(Debix Som). With the current code it is impossible to get full range
YUV data by selecting color space JPEG (fixed by patch 1). But even
explicitly setting the range to full range results in image artifacts
due to incorrect range handling in CPROC (fixed by patch 2).
Please see the individual patches for more details.
Best regards,
Stefan
