Portrait mode is used, when you take pictures of single object, and you dont want too much exposure of background. Selecting Portrait mode tells your camera to use large aperture which helps to keep your background out of focus. In this mode try to focus on object either by zooming in or walking closer, so that your object appears clear and focussed.
