INFORMATION PROCESSING DEVICE, AND INFORMATION PROCESSING METHOD

PROBLEM TO BE SOLVED: To provide a highly convenient map display technology.SOLUTION: For each object, a map, and composite position information for identifying a composite position of the object on the map are managed in association with each other. Each time input information including position information is input, an input frequency of the position information is counted up and managed in association with the position information. When the input frequency after the counting up exceeds a prescribed value, position information managed in association with the input frequency, and an object associated with the composite position information representative of the position are managed in association with a map of a reduction scale smaller than a reduction scale of the associated map. On a map of a specified reduction scale, an object managed in association with the map of the specified reduction scale is synthesized therewith and displayed.
