Samsung Galaxy A21 ImageCapture returns only 8MP image instead of 16MP

[Hiren Patel]

Using the latest CameraX release, I have setup an ImageCapture use case as below.

imageCapture = ImageCapture.Builder()
.setCaptureMode(ImageCapture.CAPTURE_MODE_MINIMIZE_LATENCY)
.setTargetAspectRatio(AspectRatio.RATIO_4_3)
.setTargetRotation(rotation)
.build()

The output image received has dimenstions of 3264x2448. When using the native camera app capturing in 4:3 aspect ratio yeilds an image of size 4608x3456.

How would one go about requesting imageCapture to capture at the highest possible resolution?

Thank you

Hi Hiren,

CameraX selects an available size that is obtained by StreamConfigurationMap#getOutputSizes(). Some devices may support extra high resolutions that are listed in StreamConfigurationMap#getHighResolutionOutputSizes(). I guess the case mentioned by you should be caused by this reason.

There is an issue to track this feature request. Please refer to https://b.corp.google.com/issues/162121234. This might be added when CameraX enters the next alpha stage to add new APIs.
