Claim of US Patent No. 9,462,216

1. A recording apparatus comprising:
a connection unit configured to connect the recording apparatus to an image capture apparatus, the image capture apparatus
being configured to perform an image capture operation to capture an image, based on a capturing instruction generated at
a generation timing;

an acquisition unit configured to acquire a plurality of pieces of position information by repeating positioning processing
by a first time interval periodically, wherein the plurality of pieces of position information acquired by the acquisition
unit are stored in a temporary storage device, and the positioning processing is executed, irrespective of whether or not
the image capture apparatus performs the image capture operation; and

a recording control unit configured to record, in one log file of a permanent storage device, a plurality of pieces of position
information, wherein the plurality of pieces of position information recorded in the one log file is a subset of the plurality
of pieces of position information acquired by the acquisition unit and each piece of position information recorded in the
one log file corresponds to position information acquired by a second time interval periodically, the second time interval
being (i) a logging time interval and (ii) an interval that is longer than the first time interval,

wherein, when a capturing instruction to request the image capture apparatus to capture an image is generated, the recording
control unit records, in the one log file of the permanent storage device from the temporary storage device, position information
that corresponds to the generation timing of the capturing instruction and that is a subset of the plurality of pieces of
position information acquired by the acquisition unit by the first time interval, irrespective of whether or not the generation
timing corresponds to the second time interval, and the one log file includes the position information acquired by the second
time interval periodically and the position information that corresponds to the generation timing of the capturing instruction.
