Description

The present invention relates to an image pickup apparatus and a control method, and more particularly to a technique suitable for use in obtaining position information using a position information measuring device built in the image pickup apparatus.

An imaging device according to the present invention is an imaging device, which captures a subject image and obtains a captured image, an acquisition unit that receives a signal from an external device and acquires current position information, and the acquisition unit and associating means for acquiring position information and associate with the captured image by a detection means for detecting a state of the imaging device, based on the result of detection by said detection means, determination means for determining the amount of movement of the imaging device have, when the said determining means and the imaging means and the imaging device to complete acquisition of the positional information by the acquiring means from the imaging by the moves a predetermined amount is determined, the association means includes position information and the photographed image It is characterized in that the association is not performed.

Thereafter, the process proceeds to S203, where it is determined whether or not the photographer has operated the shooting button included in the operation unit 105. If the shooting button has not been pressed, the process proceeds to S204, and it is determined whether or not the acquisition of the GPS position information started in S201 has been completed. If it is determined that the acquisition of the GPS position information is completed, the process proceeds to S205, where the acquired position information is updated, the latest position information is held in the RAM, and the process returns to S202. On the other hand, if it is determined in S204 that the acquisition of the GPS position information has not been completed, the process directly returns to S203 . As described above, the position information is repeatedly updated until it is determined in S203 that the photographing button is operated, so that the latest position information is always held in the RAM.
