[RFC PATCH 2/8] media: v4l: Add 10-bit RGBIr formats
From: Rishikesh Donadkar
Date: Fri Sep 25 2026 - 09:32:44 EST
From: Jai Luthra <j-luthra@xxxxxx>
Some camera sensors now use an expanded CFA pattern to capture near-IR
light along with the visible spectrum (R,G,B). This allows capturing
light in both low-light and day-light scenarios using the same sensor.
Instead of having a 2x2 repetition of B,G,R like in older bayer formats,
here we have a 4x4 repetition of B,G,R,Ir where the number of G pixels
are the same, but half the B and R pixels are replaced with Ir. Thus
instead of having 4 total phases, we now have 8 total phases or
re-arrangements of this pattern.
