Abstract

A portable terminal device provided with: a gyro sensor measuring an angular velocity to acquire angular velocity information; an acceleration sensor measuring an acceleration to acquire acceleration information; a camera capturing an image of a subject in surroundings to acquire image information; a vector calculation unit calculating a motion vector of the subject based on the image information; a correlation decision unit deciding a relative relation between a traveling direction by a walking motion of the user and an image-capturing direction of the camera in accordance with the angular velocity information and the acceleration information; a rectilinear walking decision unit deciding whether the user is in a rectilinear state in accordance with the calculated motion vector of the subject and correlation decision information; and a correction unit correcting the angular velocity information acquired by the gyro sensor in response to decision that the user is in the rectilinear state.
