Patent ID: 7890121

Claim:
A position measurement system comprising first and second portable terminals which comprise short distance wireless communication means for performing short distance wireless communication, and which performs position measurement using a signal transmitted from a satellite via radio waves, wherein: the first portable terminal comprises: signal reception means which receives a signal transmitted from a satellite via radio waves; signal transfer means which transfers the signal received by the signal reception means to the second portable terminal using the short distance wireless communication means; and mobile telephone communication means which performs communication with other terminals via a mobile telephone network; and the second portable terminal comprises: position measurement means which, when the signal which has been transmitted by the signal transfer means of the first portable terminal has been received by the short distance wireless communication means, measures the position of the first portable terminal based upon the received signal; position measurement result notification means which notifies the position of the first portable terminal which has been measured by the position measurement means to the first portable terminal, using the short distance wireless communication means; image capture means which captures an image of an image capture area; and captured image storage means which stores a captured image of an image capture area which has been captured by the image capture means, and the position of the first portable terminal which has been measured by the position measurement means directly before the capturing of the captured image, in mutual correspondence.
