ENUM RKISP1_CIF_ISP_EXP_MEAS_MODE(9)

📦 version 7.3.1, in nixpkgs unstable

💅 enum rkisp1_cif_isp_exp_meas_mode(9) — the Kernel API Manual glow-up 🎀

okay so bestie, welcome to the Kernel API Manual page for enum rkisp1_cif_isp_exp_meas_mode(9). it's a whole enum, she's iconic, and she's about to tell you how your camera figures out how bright stuff is. stay with me. ✨

🌸 NAME 🌸

enum rkisp1_cif_isp_exp_meas_mode — Exposure measure mode. that's it, that's the whole vibe check: it's the enum that names the ways the ISP can measure exposure. 💖

✨ SYNOPSIS ✨

here's the literal shape of her, no cap, copy it exactly:

enum rkisp1_cif_isp_exp_meas_mode {
    RKISP1_CIF_ISP_EXP_MEASURING_MODE_0 ,
    RKISP1_CIF_ISP_EXP_MEASURING_MODE_1

};

two constants, one enum, zero notes. periodt. 💅

🦋 Constants 🦋

okay so each of these is literally just a luma formula — like, how do we squish R, G and B into one Y. she's doing math and she's slaying:

  • RKISP1_CIF_ISP_EXP_MEASURING_MODE_0 — the fancy weighted one: Y = 16 + 0.25R + 0.5G + 0.1094B
  • RKISP1_CIF_ISP_EXP_MEASURING_MODE_1 — the "just average it out" one: Y = (R + G + B) x (85/256)

no gatekeeping, both formulas are right there. pick your fighter. ⭐

not me listing every single one 😭 but the rule is the rule: nothing gets left behind. 🫶

and that's the page!! 💜 this little love letter comes from ./include/uapi/linux and she's stamped October 2026 — so like, future icon behavior. go measure some exposure, bestie, you've got this. 🌈👑🎀
