讨论的很有意义
Well, now on 1.5, the documentation has been updated: "If the EXTRA_OUTPUT is not
present, then a small sized image is returned as a Bitmap object in the extra field.
If the EXTRA_OUTPUT is present, then the full-sized image will be written to
the Uri value of EXTRA_OUTPUT."

But using the following piece of code:

    private void takePic2() {
        Intent imageCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        imageCaptureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(new File(FILE_PATH)));
        startActivityForResult(imageCaptureIntent, 1);
    }
The doc says:
1/ "If the EXTRA_OUTPUT is not present, then a small sized image is returned"
2/ "If the EXTRA_OUTPUT is present, then the *full-sized* image will be written"

Alas 2/ is not true, it produces a 512x384 image - that is not "full sized".
