+#### Gemini 330 AE/AWB Debugging
+
+On Gemini 330 series devices with firmware `1.8.21` or later, the following services are advertised when the corresponding SDK properties are supported:
+
+*   `/camera/get_color_ae_awb_status`
+
+    Returns the device AE/AWB status value.
+
+    ```bash
+    ros2 service call /camera/get_color_ae_awb_status orbbec_camera_msgs/srv/GetInt32 '{}'
+    ```
+
+*   `/camera/get_color_awb_gain`
+
+    Returns the raw Q8.8 `r_gain`, `b_gain`, and `g_gain` values.
+
+    ```bash
+    ros2 service call /camera/get_color_awb_gain orbbec_camera_msgs/srv/GetAwbGain '{}'
+    ```
+
+*   `/camera/set_color_awb_gain`
+
+    Sets raw Q8.8 RGB channel gains. Color auto white balance must be disabled before setting the gains.
+
+    ```bash
+    ros2 service call /camera/set_color_awb_gain orbbec_camera_msgs/srv/SetAwbGain "{r_gain: 512, b_gain: 512, g_gain: 512}"
+    ```
+
 *   `/camera/set_laser_enable`
     ```bash
     ros2 service call /camera/set_laser_enable std_srvs/srv/SetBool '{data: true}'

+#### Gemini 330 AE/AWB 调试
+
+Gemini 330 系列设备使用固件 `1.8.21` 及以上版本时，如果设备支持对应 SDK 属性，节点会提供以下服务：
+
+*   `/camera/get_color_ae_awb_status`
+
+    获取设备 AE/AWB 状态值。
+
+    ```bash
+    ros2 service call /camera/get_color_ae_awb_status orbbec_camera_msgs/srv/GetInt32 '{}'
+    ```
+
+*   `/camera/get_color_awb_gain`
+
+    获取原始 Q8.8 格式的 `r_gain`、`b_gain` 和 `g_gain`。
+
+    ```bash
+    ros2 service call /camera/get_color_awb_gain orbbec_camera_msgs/srv/GetAwbGain '{}'
+    ```
+
+*   `/camera/set_color_awb_gain`
+
+    设置原始 Q8.8 格式的 RGB 通道增益。设置前必须关闭彩色自动白平衡。
+
+    ```bash
+    ros2 service call /camera/set_color_awb_gain orbbec_camera_msgs/srv/SetAwbGain "{r_gain: 512, b_gain: 512, g_gain: 512}"
+    ```
+
 *   `/camera/set_laser_enable`
     ```bash
     ros2 service call /camera/set_laser_enable std_srvs/srv/SetBool '{data: true}'
