Abstract:
1. A mobile terminal, comprising: a mobile communication module configured to communicate with a mobile network; a memory unit storing celestial information including images of celestial bodies and position information of the celestial bodies on a celestial sphere; an input unit configured to receive a user-selected time different from a current terminal time; an information acquiring unit configured to acquire the current terminal time, a current terminal position, and a current terminal pointing direction including three-dimensional azimuth and altitude coordinates of the mobile terminal; a displaying unit; and an information processing unit configured to extract and display a stored image of a celestial body on the displaying unit that 1) corresponds with the current terminal pointing direction including the three-dimensional azimuth and altitude coordinates of the mobile terminal without having to view a range of the sky, and 2) that corresponds with at least one of the user-selected time and the current terminal time, wherein when the acquired current terminal pointing direction including the three-dimensional azimuth and altitude coordinates indicates the terminal is pointed downward towards the Earth, the information processing unit is further configured to extract and display a stored image of a celestial body of the sky on the opposite side of Earth corresponding to said at least one of the user-selected time and the current terminal time.
