Use procedure 1 (Set the camera mode to single-through-5m and the preview resolution
to VGA)
In this example, the width and height of the image are reduced to approximately 1/4 and
displayed in a preview.
Use procedure 2 (when preview has already started)

Remarks

After setting the preview resolution in setPreviewSize, be sure to perform
setParameters . Changed content is not reflected until setParameters is executed.

When the preview has already started, use stopPreview to temporarily stop the
preview.

Each preview resolution has a limited combination of frame rates and camera
modes. Note that a run-time exception will occur in setParameters for
combinations that exceed the limit.

You cannot set single-through-5m or side-by-side as the preview resolution. If
you want to acquire images in single-through-5M or side-by-side, perform
shooting by using takePicture.

The resolution set for preview resolution uses image data acquired in
PreviewCallback.
