• wherein the mobile terminal includes:
• a body that is configured to be portably held by a user;
• an image sensor that is provided in the body and is configured to pick up the image of the subject via lens provided in the body;
• a locator that is provided in the body and is configured to output position information of the mobile terminal;
• a transmitter;
• and
• a memory,
• wherein the information search system includes:
• a database in which the information on the subject is stored in correspondence with the position information and the image of the subject;
• and
• an information search server that searches for the information on the subject from the database based on the position information and the image of the subject, and
• wherein the mobile terminal further includes:
• a touch panel display that is provided in the body and that is configured to display the image of the subject and the information on the subject;
• and
• a controller that is provided in the body and is configured to:
