STRUCT C3_ISP_PARAMS_AE_CONFIG(9)

💅 NAME 💅

struct c3_isp_params_ae_config — the stats settings for auto-exposure, bestie ✨

So like, this is a page straight out of the Kernel API Manual (yes, that's the manual name, we're fancy now 👑), and it's all about one struct. Let's get into it 🫶

---

🌸 SYNOPSIS 🌸

struct c3_isp_params_ae_config {
    struct c3_isp_params_block_header header;
    __u8 tap_point;
    __u8 horiz_zones_num;
    __u8 vert_zones_num;
    __u8 zone_weight[C3_ISP_AE_MAX_ZONES];
    __u16 horiz_coord[C3_ISP_AE_MAX_PT_NUM];
    __u16 vert_coord[C3_ISP_AE_MAX_PT_NUM];
    __u16 reserved[3];
 };

That's the whole vibe right there, no cap 💖

🎀 Members 🎀

Okay so every field, one by one, and yes I'm doing all of them because we don't skip 💅

• header — the C3 ISP parameters block header. The little intro card for the block, iykyk ✨
• tap_point — the tap point, and it comes from enum c3_isp_params_ae_tap_point. Pick your fave from the enum, periodt 🦋
• horiz_zones_num — how many horizontal zones are actually active, range [0..17] 🌈
• vert_zones_num — how many vertical zones are actually active, range [0..15] ⭐
• zone_weight — the array of weights for the AE statistics zones, range [0..15]. It's giving "give each zone its moment" 💀
• horiz_coord — the horizontal coordinate of points on the diagonal, range [0..2888] 🔥
• vert_coord — the vertical coordinate of points on the diagonal, range [0..2240] 🔥
• reserved — applications must zero this array. Not optional, not a suggestion, zero it 🙈

✨ Description ✨

So this struct is literally the thing that lets you configure the statistics generated for auto exposure. That's the whole point of it, and it ate 💅

And a lil detail you cannot miss: header.type should be set to C3_ISP_PARAMS_BLOCK_AE_CONFIG, which comes from :c:type:c3_isp_params_block_type``. Set it. Don't forget. Mwah 🫶
