[FAQ17385]录像打开EIS后画面变的突然很暗

移动开发
[DESCRIPTION]
 
 
录像打开EIS后,画面变得很暗.
 
 
[SOLUTION]
 
[MT6735/53,MT6755,MT6732/52]
 
 1. 没开EIS, recording是动态帧率.
 
 2. 打开EIS后, recording是固定帧率为30fps.
 
 帧率固定以后,画面会变暗.
 
 解决办法:
 
/vendor/mediatek/proprietary/custom/[platform]/hal/camera/camera_custom_eis.cpp

 

bool GetEisLinkWithDfr()

{

      return true;   // true : dynamic frame rate off when eis on; false : dynamic frame rate on when eis on 

}

 
 将return ture修改为false, 打开EIS后不会固定录像的帧率.

    cam3aParam.u4ShotMode   = mpParamsMgr->getShotMode();

    cam3aParam.i4RotateDegree = mpParamsMgr->getInt(MtkCameraParameters::KEY_ROTATION);
////////将下面这行////
    cam3aParam.bVideoStabilization = (mpParamsMgr->getVideoStabilization(); 
/////////////////改成/////
cam3aParam.bVideoStabilization = 0;
