The advantage of linear zoom is that it ensures the field of view (FOV) scales with changes in zoom. Due to this, there is some blank space on the top and bottom of my PreviewView. In these cases, the callbacks are still only dispatched directly to the camera executor. CameraX keeps only the latest outstanding setExposureCompensationIndex() request, and calling the function multiple times before the previous request gets executed results in its cancellation. may not include reverse portrait/reverse landscape). With our class implementing the ImageAnalysis.Analyzer interface, all we need to do is instantiate an instance of LuminosityAnalyzer in the ImageAnalysis, similar to other use cases, and update the startCamera() function once again, before the call to CameraX.bindToLifecycle(): The VideoCapture use case is new to the CameraX use case family, and emulators may expose different behavior. android camera,AndroidCameraX_JunJIe.Y- android camera For more It is intended. When providing a custom executor or scheduler handler, we recommend using ones that do not execute code on the main thread. This is often used to implement the tap to focus feature in many camera applications.
