1.1 常見編譯報錯：

sensorlist.cpp:vtable for NSFeature::RAWSensorInfo<8710u>: error: undefined reference to
'NSFeature::RAWSensorInfo<8710u>::impGetDefaultData(CAMERA_DATA_TYPE_ENUM, void*, unsigned int) const'

1.2 閃光燈一直打閃

修改 hal 層 camera_AE_PLineTable_s5k5e2yafmipiraw.h 檔案中所有的 strAETable 結構體第三個成員值：

static strAETable g_AE_PreviewAutoTable =
{
 AETABLE_RPEVIEW_AUTO, //eAETableID 134, //u4TotalIndex
 0, // 20, //i4StrobeTrigerBV 這個值越小越不容易打閃（可為負數，最小已試過-30），值越大越容易打閃
 120, //i4MaxBV -13, //i4MinBV
 90, //i4EffectiveMaxBV -10, //i4EffectiveMinBV
 LIB3A_AE_ISO_SPEED_AUTO, //ISO SPEED sPreviewPLineTable_60Hz, sPreviewPLineTable_50Hz,
 NULL,
};
 

1.3 曝光表：

alps\vendor\mediatek\proprietary\custom\mt6580\hal\camera_3a\ae_tuning_custom_main.cpp
修改對應 EV=+-3,+-2,+-1,0 所對應的值（手機相機設定裡面一般就這 7 個等級），改大或改小，可以使曝光亮度增大或減小。

static MUINT32 g_strEVValueArray[25] =

 1024, // EV 0 1160, // EV 0.3 1261, // EV 0.5 1370, // EV 0.7
