Using the Hybrid-GPS
In addition to conventional Global Positioning System (GPS) system capabilities that 
determine your current location and time based on radio waves it picks up from GPS 
satellites, your EXILIM camera also features a built-in independent motion sensor 
employing autonomous positioning technology that uses a 3-axis bearing sensor and 
a 3-axis accelerometer. These two capabilities combine to create a Hybrid-GPS that 
provides position information (latitude and longitude), even indoors, underground, 
and in areas where GPS satellite waves cannot be received.
The Hybrid-GPS supports all of the following capabilities.
• Recording current location information (latitude, longitude, camera aiming 
direction) with image data (snapshots and movies)
• Recording current location name with image data (snapshots and movies)
• Direct stamping of the recording location name in an image (snapshots)
• Display of recorded images and location on a map
• When traveling, searching for photogenic spots near your current location
• Tracking your movements on a map
• Automatic updating of the camera’s clock based on GPS satellite wave data
A Global Positioning System (GPS) uses radio waves sent from GPS satellites 
orbiting the Earth to calculated positions anywhere on the globe. Signals from GPS 
satellites can be used to determine a person’s current location and the current time 
at that location.

to operate and periodically perform positioning, even when the camera is turned 
off. Whenever you are instructed to turn off all digital devices, such as during 
aircraft takeoffs and landings, be sure to change the camera’s “GPS” setting to 
“Off” and then turn off the camera.
NOTE
• The first GPS satellite receive operation may take more time than normal.
• When “On” is selected for the “GPS” setting, the camera will continually acquire 
position data (latitude, longitude) while turned on, and intermittently acquire 
position data while turned off.

direction) for your current location.
• In the case of a snapshot, the location information is recorded when you press 
the shutter button all the way down. For a movie, the location information is 
recorded when you press [0] (Movie).
.Checking GPS Wave Conditions
An icon on the display shows current GPS wave conditions. Be sure to check this 
icon before recording an image.
Recording Location Information with Image Data 
(Record Lat/Long)
IconGPS Wave Conditions
GPS satellite waves being received. GPS measurement location 
information can be recorded with image data.
GPS satellite wave reception is poor, so GPS measurement location 
information cannot be recorded with image data. In this case, motion 
sensor location information will be recorded with image data.
GPS satellite waves cannot reach your location, so GPS position 
information cannot be recorded with an image. The camera can, however, 
save position information produced by the motion sensor.
GPS is turned off (page 92).

							94Using the Hybrid-GPS
NOTE
• You can delete recorded latitude, longitude, and direction data as required (page 
109).
• Recorded latitude, longitude, and direction data cannot be edited.
• Shooting an image while on the move may result in incorrect position information 
being registered with the image.
• The current “Record Lat/Long” setting is ignored while “Off” is selected for the 
“GPS” setting (page 92).
• Note that location information recording is turned on under initial factory default 
settings. If you do not want latitude, longitude, and direction data recorded with 
image data, be sure to change the “Record Lat/Long” setting to “Off”.
• Location information is recorded along with any snapshots and movies you shoot 
while “On” is selected for “Record Lat/Long”. Remember that when you hand such 
image data over to another person or publish it on the Internet or via any other 
electronic means, the location information is included with the image data you hand 
over or publish. If you do not want location information made public with your 
image, use the “Delete Site Info” command (page 109) to delete it from the image, 
or do not record location information when you shoot the original snapshot or 
movie.
You can select from among approximately 1 million place names (country names, 
landmark names) in camera memory and insert one into your image data (snapshots 
and movies).
1.In the REC mode, point the camera at the 
subject.
Based on the measurement of your current location 
(latitude and longitude), the camera will display a 
candidate place name (country name, landmark 
name).
2.Use [4] and [6] to select the place name you want to insert into the 
image data.
• There can be up to six candidates for a place name.
• No place name will be inserted when “– – –” (blank) is displayed for the place 
name.
• If you select “– – –” (blank), the place name candidate display will disappear 
from the display after about two seconds. Pressing [4] or [6] at this time will 
cause the place name candidate display to reappear.
• If a place name is too long to fit on the display, it will scroll on the display.
3.Press the shutter button (if you are shooting a snapshot) or [0] (Movie) 
(if you are shooting a movie).
This will record the image along with the place name.

.About place names
• Place name candidates are those selected from among the country and landmark 
names in camera memory based upon current latitude and longitude 
measurements.
• “– – –” will be shown in place of the candidates if there is no appropriate place 
name at your current latitude and longitude.
• Note that displayed place names are not precise and are meant as general 
suggestions only. Certain conditions may result in the suggestion of incorrect place 
name candidates.
• Some landmark names may not match the proper formal name of a landmark.
• There is no guarantee that a place name desired by you is included in the names 
included in camera memory.
• Shooting an image while on the move may result in incorrect place names being 
displayed as candidates.
• Insertion of a place name is not supported while “Off” is selected for the “GPS” 
setting (page 92).
NOTE
• You can delete inserted place name data from images as required (page 109).
• Inserted place name data cannot be edited (page 94).

							96Using the Hybrid-GPS
You can use this procedure to select from among the place names (country names, 
landmark names) in camera memory and stamp a place directly into the image 
(snapshots).
IMPORTANT!
• Unlike place name insertion, once a place name is stamped into a snapshot, it 
cannot be edited or deleted.
1.In the REC mode, press [MENU].
2.On the “Set Up” tab, select “Stamp Place” and then press [6].
3.Use [8] and [2] to select “On” and then press [SET].
4.Point the camera at the subject and then use the same procedure as 
that under “Inserting the Place Name into Image Data (Insert Place)” 
(page 94) to select a place name.
5.Press the shutter button to shoot.
This will record the image with the place name stamped in it.
NOTE
• Place name stamping is disabled when certain BEST SHOT scenes are being 
used.
• Shooting an image while on the move may result in the incorrect place name being 
stamped into the image.
• Insertion of a place name is not supported while “Off” is selected for the “GPS” 
setting (page 92).

							97Using the Hybrid-GPS
• Better GPS satellite wave reception can be attained by 
holding the camera still with the GPS antenna pointed 
towards the sky.
• Since GPS satellites are constantly moving, your location, 
the time of day, and other conditions may cause it to take 
some time before positioning can be performed. In some 
cases, positioning may not be possible.
• Good reception is not possible in the locations listed below due to blockage or 
reflection of GPS satellite waves. For good wave reception, move outside where 
there is an unobstructed path to the sky above.
– Inside of a building or underground
– Among high-rise buildings
– Under an overhead structure
– Inside of a tunnel
– Near high-voltage wires
– Inside of dense foliage
• When carrying the camera around, do not place it into a metal case. A metal 
enclosure makes it impossible for the camera to receive GPS satellite waves.
• Nearby magnetic and metal can cause sensor errors. Keep the camera as far away 
as possible from magnets and metal.
• Nearby mobile phones and other devices that use the 1.5GHz band radio waves 
can interfere with the camera’s GPS satellite wave reception.
• Depending on wave conditions, GPS satellite positioning is subject to error of 
hundreds of meters.
• When you are in a location where the camera is unable to receive GPS satellite 
waves, positioning accuracy may be relatively lower than in locations where waves 
can be received.
• Reception may take a number of minutes the first time you perform GPS satellite 
wave reception after purchasing the camera, after the camera was continually in an 
area where satellite wave reception was impossible for a long time, or after leaving 
the camera without a battery loaded for a long time.
Precautions when Using the Hybrid-GPS

							98Using the Hybrid-GPS
• The Hybrid-GPS is able to provide position information (latitude and longitude) 
even under conditions where waves cannot be received from GPS satellites. 
However, relying solely on the motion sensor for long periods where GPS satellite 
reception conditions are poor, under an underpass or on a steel bridge, or in the 
vicinity of buildings, pedestrian bridges, electrical equipment, steel desks, steel 
chairs, or other objects that generate magnetism can result in bearing, latitude, and 
longitude reading errors. In order to ensure that position information is as accurate 
as possible, it is recommended that you occasionally move to an area where there 
is an unobstructed path to the sky above to perform GPS satellite wave reception. 
The motion sensor uses GPS satellite wave reception data to calibrate its own 
data.
• The direction sensor may not be able to perform direction measurements under 
any of the following conditions.
– Immediately after “On” is selected for the “GPS” setting (page 92)
– Immediately after loading the battery and turning on the camera
• Do not operate the GPS function while operating a motor vehicle.
• The GPS function of this camera uses WGS84 (World Geodetic System 1984).
