Position registration apparatus, non-transitory, computer readable storage medium and method of controlling position registration apparatus

A non-transitory, computer readable storage medium storing a position registration program causing a position registration apparatus to measure positions according to a process comprising:

• detecting an event occurrence;
• specifying a first position by acquiring, from outside, information that can specify a position;
• detecting an amount of movement of the position registration apparatus as movement information;
• accumulating the movement information detected at least not before the detected event occurrence;
• and
• when the first position of the position registration apparatus is acquired, causing the position registration apparatus to conduct processing to specify the amount of movement of the position registration apparatus from a point of time of the event occurrence to a point of time where the information that specifies a position of the position registration apparatus from the point of time of the event occurrence acquired from outside of the position registration apparatus, and to specify a second position of the position registration apparatus at the point of time of the event occurrence based on the specified first position of the position registration apparatus and from the specified amount of movement of the position registration apparatus.

A method of controlling a position registration apparatus to measure positions comprising:

• detecting an event occurrence by the position registration apparatus;
• specifying a first position by acquiring, from outside, information that can specify a position;
• detecting an amount of movement of the position registration apparatus as movement information;
• accumulating the movement information detected at least not before the detected event occurrence;
• and
• when the first position of the position registration apparatus is acquired, causing the position registration apparatus to conduct processing to specify the amount of movement of the position registration apparatus from a point of time of the event occurrence to a point of time where the information that can specify a position of the position registration apparatus from the point of time of the event occurrence acquired from outside of the position registration apparatus, and to specify a second position of the position registration apparatus at the point of time of the event occurrence based on the specified first position of the position registration apparatus and from the specified amount of movement of the position registration apparatus.
