图像清晰度差的Android相机

Question

我正在使用此代码...

   iv.setOnClickListener(new View.OnClickListener() {


            @Override
            public void onClick(View v) {

                Intent cameraIntent ;

                    cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                    startActivityForResult(cameraIntent, CAMERA_REQUEST);


            }
        });

      public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
            Bitmap picture = (Bitmap) data.getExtras().get("data");

            iv.setImageBitmap(picture); 
        }
}

存储到位图的图像清晰度很差。只有4kb。如何提高图像的清晰度？

你有没有尝试过这一行

 cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
