Abstract: An operation state acquisition unit 101 acquires the position of a train on a track. A determination unit 102 determines whether the train is traveling as scheduled by comparing the position of the train on the track with the target position of the train on the track if traveled in accordance with the operation schedule. A presentation mode selection unit 103 selects a presentation mode indicating a positional relationship between the train and the target on the track according to a state of being late, early or on time in accordance with the determination result of the determination unit 102. The display unit 104 displays in a representation mode selected by the presentation mode selection unit 103.

Abstract: A screen creating unit selects component contents for displaying a station name array, in which a plurality of station names on a route are arrayed in order of arrival, from a component-content storing unit, moves, according to component arrangement definition data and component motion definition data, the component contents little by little in an array direction from a state in which only a part of station names on a starting station side among the station names are arranged in a scroll display region to a state in which only a part of station names on a terminal station side are arranged, and creates an image of only a portion in the scroll display region without creating the image of a portion outside the scroll display region among the component contents to thereby create a plurality of frames continuous in time series.
