e-sensor是真么东西？下面还写着Power SavingMode，一出来电脑屏幕就暗掉了，应该怎么解决？
e-sensor：通过感应器（电子红外传感器），能够感知用户是否离开电脑桌，从而自动将显示器亮度降至最低，以达到最佳节能省电的效果。用户可以定义的传感器监测和用户之间的距离，感应距离可以选择远、平均、近三档，（有的显示器设计为“60厘米，75厘米，90厘米，120厘米”四档）.选择“近”，显示器的感应距离为1米左右，一般默认“平均”即可。如果用户离开显示器时间超过3S，此功能将自动开启。电子传感器热键选择：
“关”---电子传感器关闭
“60厘米，75厘米，90厘米，120厘米”
---为用户与机器之间可以选择的距离档次。默认是75厘米。例如，用户将距离调节为120CM(通过软体在OSD中控制），当人与机器的距离大于120CM就感应不到了， 小于等于120CM是能感应到的。在OSD菜单中选择电子传感器按钮：1）“永不关闭”---选择此设置传感器始终是开着的.2）目前有“10分钟，20分钟，30分钟，40分钟，50分钟，60分钟”几个档次，用户可以自己选择此功能关闭时间。3）默认是“永不关闭”。4）当热键设置e-Sensor off时，主OSD的中的e-Sensor的选项为灰色，不能被选中你自己可以调解下的。或者退出Power SavingMode 节能模式。

电脑屏幕上的Power sensor是什么意思？怎么取消？
提问者采纳
显示器本身设定了节能模式---进入显示器OSD菜单可以关闭节能模式或关闭提示。实际上就是自动降低亮度和对比度。电脑设定了节能模式---调整电源选项可以关闭节能功能这是告诉你已开启节能模式

出门在外也不愁camera预览是闪退的问题
使用ov8825 sensor时，如果是摄像预览可以点亮，如果切换到拍照预览时，apk闪退。log如下：:/ # logcat

最近做omap 平台的 camera porting,发现有个问题,就是进焦距起camera,或是在镜头前有遮挡物时起camera,预览图像是花屏. 分析认为可能由于camera启动的延迟时间太短,导致camera还未完全初时化成功就起启动,使得预览花屏. 解决方法可增加camera启动时的延迟等待. 本文出自 &rnmichelle&
