在哪里曝光是你想要的值
理想情况下,您应该查询控制范围以设置曝光的有效值。为曝光补偿添加了一个实验界面
您可以通过以下方式设置曝光:
val camera = cameraProvider.bindToLifecycle(viewLifecycleOwner, cameraSelector, preview, imageCapture)
val cameraControl = camera.cameraControl
cameraControl.setExposureCompensationIndex(exposure)
val camera = cameraProvider.bindToLifecycle(viewLifecycleOwner, cameraSelector, preview, imageCapture)
val cameraControl = camera.cameraControl
cameraControl.setExposureCompensationIndex(exposure)
