STRUCT IPU3_UAPI_AE_CCM(9)
π
struct ipu3_uapi_ae_ccm β from the Kernel API Manual π
okay bestie, sit down, because we're about to get into the AE coefficients for WB and CCM and honestly? it's giving camera-nerd excellence β¨ (that's the Kernel API Manual vibe, in case you were wondering where we got it from π)
β¨ NAME β¨
struct ipu3_uapi_ae_ccm β literally the AE coefficients for WB and CCM, no cap π¦
πΈ SYNOPSIS πΈ
okay so here's the whole shape of the thing, and yes you're gonna look at each field, i don't make the rules:
struct ipu3_uapi_ae_ccm {
__u16 gain_gr;
__u16 gain_r;
__u16 gain_b;
__u16 gain_gb;
__s16 mat[16];
};
π«Ά Members π«Ά
gain_grβ the WB gain factor for the gr channels, bestie. default?256. periodt πgain_rβ WB gain factor for the r channel. also defaults to256β¨gain_bβ WB gain factor for the b channel. yup, default256πΈgain_gbβ WB gain factor for the gb channels. you guessed it: default256πmatβ a4x4matrix that transforms the Bayer quad output from WB to RGB+Y π₯ like, it's the whole moment, honestly
π Description π
the default matrix is right here, don't lose it:
128, 0, 0, 0, 0, 128, 0, 0, 0, 0, 128, 0, 0, 0, 0, 128,
and here's the lore π§: as part of the raw frame pre-process stage, the WB and color conversion need to be applied to expose the impact of these gain operations. that's it, that's the tea β
π SEE ALSO π
first things first, the actual kernel file lives at:
