few options available. You can define them by
pressing the “Settings” Button.
1. Overlay: In the upper left corner of the
screen some text can be superimposed
on the picture. Use this entry field to
select what you want to see there. The
possible choices are: “No Overlay”, “File
name”, “Date”, “Comments”, “Author”,
“Description” or “Shooting Data”.
2. Color: Sets the color of the overlay text.
3. JPEG + RAW: Some cameras offer a
JPEG+RAW mode in which all pictures are
stored in JPEG format and in RAW format.
While browsing it can be annoying to see
every picture twice. With this setting you
can specify if you want to view only the
JPEG files, only the RAW files or both.
4. Softkey text: By default the softkey
prompts appear whenever pictures are
shown. You can decide whether these
prompts shall be seen by default or not.
While viewing the photos, by moving the
joystick up/down you can hide resp. show
the softkey prompts.

Softkey 3, “Chann”:
Have a look at the single red, green and blue

Softkey 4, “Levels”:
A histogram illustrates how pixels are
distributed. This is available for the full color

Zoom mode
There are several zooming options. When
entering the “Zoom” mode, the complete photo
is shown. By moving the joystick up/down you
can hide resp. show the softkey prompts.
You can either press the joystick (enter) or the
“Back” button to leave the zoom mode and go
back to standard picture viewing.

The GVX always starts with decoding the full
picture and keeps in memory all available
information. Zooming in, zooming out and
panning through the picture are then just a
matter of displaying the available information.
The consequence of this method is that it takes a
bit longer to get the first view but that afterwards
all other manipulations are rendered much faster.
