CommuniCorder

The video recorder has a 176 x 144 pixel (QCIF) resolution and uses real time video encoding with 3GPP
H.263 or MPEG4 compression, together with Adaptive Multi-Rate (AMR) compressed sound. For details
refer to the table on page 128. For a suitable PC Player please refer to
http://www.sonyericsson.com/p900/videoplayer.
The CommuniCorder 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 P900. With the flip open, the viewfinder is
supplemented with graphical controls and access to camera settings. For still images, the viewfinder is
always 160 x 120 pixels, irrespective of the resolution at which the picture is taken. In video modes the
viewfinder is 176 x 144 pixels. A dedicated hardware button on the side of the P900 provides fast access to
the CommuniCorder application.
Images are stored in the P900'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 using the
current settings for size and quality. Approximate JPEG file sizes are 50 Kbytes for VGA, 18 Kbytes for
QVGA and 3 Kbytes for QQVGA (for medium quality images).
Images are placed into a user-definable folder on either internal or Memory Stick storage. They may be
viewed and organized in the Pictures application, and are available for use by other P900 and third party
applications.
