从android应用内的“相机”中单击的图像模糊，并且整个图像上都有正方形图案

Question

I am developing an app that uses phone camera to click pictures. On a few phones the camera images captured has square pattern as shown in the picture. I was earlier using the default Camera intent for opening the camera. Now I use the https://github.com/commonsguy/cwac-cam2 library. Also ths problem occurs only in portrait mode and not in landscape.

 **strong text**photoFile = Camera.createImageFile(); Intent i=newCameraActivity.IntentBuilder(this) .skipConfirm() .facing(CameraActivity.Facing.BACK) .to(photoFile) .debug() .updateMediaStore() .build(); startActivityForResult(i, RESULT_CLICK_IMAGE); 

Answer 1

This happens because the image is interpolated from a TV screen. If you would take this image from a paper for example this is would not happen
