STRUCT IPU3_UAPI_BNR_STATIC_CONFIG_DN_DETECT_CTRL_CONFIG(9)

🌸 struct ipu3_uapi_bnr_static_config_dn_detect_ctrl_config 🌸

okay bestie, welcome to the Kernel API Manual ✨ — this is the page for struct ipu3_uapi_bnr_static_config_dn_detect_ctrl_config, and yes the name is a whole entire mouthful, but like… it's giving denoising config and honestly it slays 🎀

🦋 NAME 🦋

struct ipu3_uapi_bnr_static_config_dn_detect_ctrl_config — Denoising config 💖 that's it, that's the vibe.

✨ SYNOPSIS ✨

okay so here's the whole struct, look at her, look at the bit fields, she's gorgeous 👑

struct ipu3_uapi_bnr_static_config_dn_detect_ctrl_config {
    __u32 alpha:4;
    __u32 beta:4;
    __u32 gamma:4;
    __u32 reserved0:4;
    __u32 max_inf:4;
    __u32 reserved1:7;
    __u32 gd_enable:1;
    __u32 bpc_enable:1;
    __u32 bnr_enable:1;
    __u32 ff_enable:1;
    __u32 reserved2:1;
 };

💅 Members 💅

• alpha — the weight of the central element of the smoothing filter. main character of the filter fr fr 👑
• beta — the weight of the peripheral elements of the smoothing filter, default 4.
• gamma — the weight of the diagonal elements of the smoothing filter, default 4. yes bestie, diagonals have rights too 🌈
• reserved0 — reserved 🫶 (don't touch, she's resting)
• max_inf — the maximum increase of peripheral or diagonal element influence relative to the pre-defined value range: [0x5, 0xa] 🔥
• reserved1 — reserved 😴
• gd_enable — green disparity enable control, 0 - disable, 1 - enable.
• bpc_enable — bad pixel correction enable control, 0 - disable, 1 - enable. bye bad pixels 💀
• bnr_enable — Bayer noise removal enable control, 0 - disable, 1 - enable.
• ff_enable — fixed function enable, 0 - disable, 1 - enable.
• reserved2 — reserved 🧚

🎀 Description 🎀

so the tea is: beta and gamma parameter define the strength of the noise removal filter 🍓

and all of the above has precision u0.4, range [0, 0xf], format: u0.4 — no / zero bits represent whole number, 4 bits represent the fractional part with each count representing 0.0625 🧮✨ e.g. 0xf translates to 0.0625x15 = 0.9375. literally math but make it cute 💜
