<p>An information terminal for imaging a first object at a normal distance and a second object nearer than the first object readily with high precision. The information terminal has a imaging lens and an imaging device for capturing an image formed by the imaging lens. The imaging lens is a multifocal lens and composed of a first lens portion having a first focal length for imaging the first object (e.g., the user of the information terminal) at a normal distance and a second lens portion having a second focal length for imaging the second object (e.g., a bar code) nearer than the first object. The first and second lens portions are arranged on the same plane and formed in one piece. The information collected by imaging the second object is used for processings such as communication and display.</p> |
