解决方法：
为使MT6752/MTK6732 512MB RAM配置的平台开机后能够获得较为充裕的剩馀内存空间, 请参考以下位于ProjectConfig.mk与kernel config的配置。
6752/6732 512MB RAM配置最大支持到: 5M camera & fwvga。

除了这部分外，若连拍99张很容易自动退出camera，则还需要将连拍的速度做一些限制。
MultiShot.cpp (mediatek\platform\mtxxxx\hardware\mtkcam\core\camshot\multishot)
MVOID
MultiShot::
setupInitialFps()
{
// could modify capture/preview fps for picture-size/sensor size/senor type/...
muCaptureFps =5; //改为底层每秒出5张jpeg,可根据实际情况酌情调整速度
muPreviewFps = 0;
}
