Android L0 版本 awb Perference gain 不生效问题

时间：10-02 整理：3721RD 点击：

[DESCRIPTION]
CAMERA_tuning_para_sensorNamemipiraw.cpp文件中修改AWB preference color gain不起作用。
[SOLUTION]
1：MT6582/MT6592 KK 版本的AWB preference color gain 修改是在 camera_tuning_para_SensorNamemipiraw.cpp中。
即下面部分：


L 版本升级的话，增加了 针对不同 LV 下 不同色温下 AWB Preference Gain 的调整。
如果直接修改camera_tuning_para_SensorNamemipiraw.cpp 文件中 Preference Gain部分，是不会 生效的。
在 L0 版本上需要做如下修改：
sensor_awb.cpp Path：alps\vendor\mediatek\proprietary\custom\ [$platform,$project] \hal\imgsensor_src\sensor_awb.cpp中
(1) Add

  1. AWB_PARAM2_T&getAWBParam2_SensorName();

复制代码

(2)

  1. Add #if defined(SensorNameDefine)
  2. case SensorNameId:
  3. return getAWBParam2_SensorName ();
  4. #endif

复制代码

如下以 IMX135 为例说明：

  1. AWB_PARAM2_T& getAWBParam2_IMX135();
  2. AWB_PARAM2_T& getAWBParam2(int sensorId)
  3. {
  4. switch(sensorId)
  5. {
  6. #if defined(IMX135_MIPI_RAW)
  7. case IMX135MIPI_SENSOR_ID:
  8. return getAWBParam2_IMX135();
  9. #endif
  10. default:
  11. return getAWBParam2_default();
  12. }
  13. return getAWBParam2_default();
  14. }

复制代码

(3)在 alps\vendor\mediatek\proprietary\custom\ [$platform,$project] \hal\imgsensor\ SensorName SensorName \ awb_para_ SensorName.cpp里面直接修改不同 色温下不同LV 下 AWB Preference Gain 。 如下以 IMX135 为例说明：

  1. AWB_PARAM2_T& getAWBParam2_IMX135()
  2. {
  3. static AWB_PARAM2_T rAWBParam =

2：MT6595/MT6752/MT6732/MT6795 等chip L0 版本上
不同色温下不同LV 下 AWB Preference Gain的修改在 awb_tuning_custom_main.cpp或者 awb_tuning_custom_sub.cpp 档案中
但是这样的修改，会影响到 减弱的所有camera 的效果。
awb_tuning_custom_main.cpp或者awb_tuning_custom_sub.cpp 档案 路径：
alps\vendor\mediatek\proprietary\custom\ [$platform,$project] \hal\camera_3a\awb_tuning_custom_main.cpp
因此如果要客制化不同 色温下不同LV 下 AWB Preference Gain的话，建议参考如下说明：

  1. sensor_awb.cpp
  2. Path：alps\vendor\mediatek\proprietary\custom\ [$platform,$project]

复制代码

\hal\imgsensor_src\sensor_awb.cpp中
(1) Add

  1. AWB_PARAM2_T&getAWBParam2_SensorName();

复制代码

(2) Add

  1. #if defined(SensorNameDefine) case SensorNameId:
  2. return getAWBParam2_SensorName ();
  3. #endif

复制代码

如下以 IMX135 为例说明：

  1. AWB_PARAM2_T& getAWBParam2_IMX135();
  2. AWB_PARAM2_T& getAWBParam2(int sensorId)
  3. {
  4. switch(sensorId)
  5. {
  6. #if defined(IMX135_MIPI_RAW)
  7. case IMX135MIPI_SENSOR_ID:
  8. return getAWBParam2_IMX135();
  9. #endif
  10. default:
  11. return getAWBParam2_default();
  12. }
  13. return getAWBParam2_default();
  14. }

复制代码

(3)在 alps\vendor\mediatek\proprietary\custom\ [$platform,$project] \hal\imgsensor\ SensorName SensorName \ awb_para_ SensorName.cpp里面直接修改不同
色温下不同LV 下 AWB Preference Gain 。 如下以 IMX135 为例说明：

  1. AWB_PARAM2_T& getAWBParam2_IMX135()
  2. {
  3. static AWB_PARAM2_T rAWBParam =
  4. { {
  5. // LV0 LV1 LV2 LV3 LV4 LV5 LV6 LV7 LV8 LV9
