Built-In CommuniCam
The P800 has a built-in camera capable of taking still pictures up to 640 x 480 pixel (VGA)
resolution (307200 pixels) and 24 bit colour depth. 320 x 240 (QVGA) and 160 x 120 (QQVGA)
pixel sizes are also selectable. The camera may be used in Flip Closed mode for fast point-and-
shoot pictures using the screen as the viewfinder. The lens is recessed into the back of the P800.
With the flip open, the viewfinder is supplemented with graphical controls and access to camera
settings. The viewfinder is always 160 x 120 pixels, irrespective of the resolution at which the
picture is taken. A dedicated hardware button provides fast access to the camera application.
Images are stored in the P800’s filing system and are therefore available for other applications to
use. The number of images that can be stored depends on the available file space, which is
shared with other applications. In FO mode, the viewfinder will give an estimation of the number
of images remaining, assuming that all of the free storage is available for the camera application
and using the current settings for size and quality. Approximate JPEG file sizes are 50kbytes for
VGA, 18kbytes for QVGA and 3kbytes for QQVGA.
Images are placed into a user-definable folder on either internal or Memory Stick storage. They
may be viewed and organised in the Pictures application, and are available for use by other P800
and third party applications.
In Flip Closed mode, the camera is optimised for
‘point-and-shoot’ speed:
•
Dedicated CommuniCam button
•
Ready/Busy indicator
• Delay Timer icon
.The timer gives an
audible 15 second ‘countdown’ to the shot.
The first press on the CommuniCam button will
switch on the viewfinder. Each further press on the
button will then act as a shutter and take a picture.
With the flip open, additional on-screen controls are:
• Shutter
• View all pictures (shortcut to Pictures)
Settings are accessed via the CommuniCam menu
and include:
• Image size
• High/Medium/Low quality (low uses least
storage space)
•
Brightness and Contrast
• Backlight mode (when there is light behind
the subject in the viewfinder)
• Flicker-free mode (for fluorescent lighting)
•
White Balance (automatic or one of 4 pre-set
values)
Pictures remaining is calculated based on the current
settings plus available space on the selected storage
location (internal or Memory Stick).
