android 照相以及关于自动生成的图片分辨率和面积太小问题

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".
