3.4 Camera Settings
3.4.1 Camera Settings: Standards
One of the most interesting properties of the FireWire-CAM-001/002
is that they are based on standards that are widely circulated. One of
these standards is called
DCAM
. It describes the parameters and the
data structures of IEEE 1394 cameras that do not feature audio
processing and transmit the picture data uncompromised. Additional
information on DCAM can be found in
section 4, “The Software
Concept”
.
Note:
Please note that some FireWire-CAM models offer setting options in
addition to these DCAM parameters, which can be very useful in
certain applications, but are not (yet) included in the DCAM
specification. In the following sections the DCAM-conformant
parameters are marked.
3.4.2 Camera Settings in Detail
All camera parameters can be set over the IEEE 1394 Bus. In order to
access these, install the camera and the included software as described
in the
section 2 „First Steps“
.
In the following section the individual setting options and their effects
are described in detail.
3.4.2.1 Camera Settings - Settings
The dialog
Settings
(
Figure 32
) offers you the selection between the
various resolutions and frame rates, therefore defining the basic
structure of the video signal.
You will achieve the highest picture quality if you use UYVY (for
FireWire-CAM-xx2) and Y800 (for FireWire-CAM-xx1) for the
color
space
and select 1024 x 768 as the
output size
.
However, these operating modes also require the highest bandwidth.
All parameters are DCAM-conformant.
For addtional information refer to section 3.6, “How to Maximize
Image Quality”.
