mt6735修改闪光灯阀值

　　相机中这有自动打闪的小图标，设置为自动打闪后，比较亮的环境下也会打开闪光灯，

这时需要修改闪光灯的阀值.

vendor/mediatek/proprietary/hardware/mtkcam/legacy/platform/mt6735/core/featureio/pipe/aaa/ae_mgr/ae_mgr.cpp

MBOOL AeMgr::IsStrobeBVTrigger(){    MBOOL bStrobeBVTrigger;    MINT32 i4Bv = 0;    strAETable strCurrentPreviewTable;    strAETable strCurrentCaptureTable;    strAETable strCurrentStrobeTable;    strAFPlineInfo strobeAEPlineInfo;    memset(&strCurrentCaptureTable, 0, sizeof(strAETable));    getCurrentPlineTable(strCurrentPreviewTable, strCurrentCaptureTable, strCurrentStrobeTable, strobeAEPlineInfo);    if(m_rAEInitInput.rAEPARAM.strAEParasetting.bEV0TriggerStrobe == MTRUE) {         // The strobe trigger by the EV 0 index        i4Bv = m_BVvalueWOStrobe;    } else {        if(m_rAEInitInput.rAEPARAM.pEVValueArray[m_eAEEVcomp]) {            if(m_pIAeAlgo != NULL) {                i4Bv = m_BVvalueWOStrobe - m_pIAeAlgo->getSenstivityDeltaIndex(1024 *1024/ m_rAEInitInput.rAEPARAM.pEVValueArray[m_eAEEVcomp]);            } else {                i4Bv = m_BVvalueWOStrobe;                MY_LOG("[%s()] The AE algo class is NULL  i4SensorDev = %d line:%d", __FUNCTION__, m_eSensorDev, __LINE__);            }        }    }    bStrobeBVTrigger = (i4Bv < strCurrentCaptureTable.i4StrobeTrigerBV)?MTRUE:MFALSE;    MY_LOG("[%s()] i4SensorDev:%d bStrobeBVTrigger:%d BV:%d %d\n", __FUNCTION__, m_eSensorDev, bStrobeBVTrigger, i4Bv, strCurrentCaptureTable.i4StrobeTrigerBV);    return bStrobeBVTrigger;}

这时我们只需adb logcat |grep bStrobeBVTrigger打印出相应的参数，找到合适的阀值，填写到camera_AE_PLineTable_xxxxxxx.h中即可

root@www$ adb logcat |grep bStrobeBVTrigger01-03 21:25:52.422   460  3320 D ae_mgr  : [IsStrobeBVTrigger()] i4SensorDev:1 bStrobeBVTrigger:1 BV:-18 2001-03 21:25:58.038   460  3320 D ae_mgr  : [IsStrobeBVTrigger()] i4SensorDev:1 bStrobeBVTrigger:1 BV:-50 2001-03 21:26:01.610   460  3320 D ae_mgr  : [IsStrobeBVTrigger()] i4SensorDev:1 bStrobeBVTrigger:1 BV:-8 20

对于拍照使用的闪光灯的阀值对于的数组为

static strAETable g_AE_CaptureAutoTable ={      ...     -45,    //u4StrobeTrigerBV      ...};

该文件用到u4StrobeTrigerBV的地方也一并修改.
