STRUCT OMAP3ISP_CCDC_BLCOMP(9)

✨ NAME ✨

okay so bestie, meet struct omap3isp_ccdc_blcomp — it's literally the Black Level Compensation parameters 🎀 (yes, this is from the Linux Kernel API Manual, section 9, and it's the main character of this whole page, no cap 💅).

🌸 SYNOPSIS 🌸

struct omap3isp_ccdc_blcomp {
    __u8 b_mg;
    __u8 gb_g;
    __u8 gr_cy;
    __u8 r_ye;
 };

like, that's the whole struct. four little __u8 besties holding your compensation values 🫶 (and yep, there's that slightly-indented closing brace — copying it exactly, iykyk, we don't edit the original 💖).

💜 Members 💜

okay so each one of these is a pixel-shade thing and they're all the same vibe, so let's get into it:

• b_mg — the B/Mg pixels value, bestie 🦋. It's 2's complement, range -128 to +127. That's it, that's the whole personality.
• gb_g — the Gb/G pixels value ✨. Also 2's complement, also -128 to +127. Consistent queen.
• gr_cy — the Gr/Cy pixels value 💅. 2's complement, -128 to +127. slay.
• r_ye — the R/Ye pixels value 🌸. 2's complement, -128 to +127. she ate, honestly.

ngl the "2's complement" thing matters — these are signed values riding in an unsigned __u8, so -128 to +127 is the real range. don't forget it fr fr 🌈

🦋 SEE ALSO 🦋

okay so if you wanna go down the rabbit hole (and you do), the kernel file is ./include/uapi/linux/omap3isp.h, and it's friends with literally everyone in the group chat:

• struct omap3isp_stat_data(9)
• struct omap3isp_ccdc_lsc_config(9)

and that's the tea ☕ — this page came from the ./include/uapi/linux directory, dated October 2026, and it's struct omap3isp_ccdc_blcomp(9) all the way down. go forth and compensate those black levels, bestie, ily 🫶💖✨🎀
