Fig. 11. The view on the control of the camera movement controls and its input/output
parameters
• “ptz camera control” controls defining the possible for realization modes of
automatic/manual movement:
o “up, down, left, right” – movement orders (rotations) for the camera
respectively up and down (“tilt”) and right and left (“pan”);
o “home” – an order of return to basic position (“pan=0”, “tilt=0”,
“zoom=1”),it is a position in which the camera is places itself after
being plugged to power;
o “pan, stop” – respectively starts or finishes the automatic Canning in
the movement/rotation plane of the camera;
o “patrol” – automatically starts the space scanning with the compliance
of the defined characteristic points in the observed area;
o “tele, wide” – respectively a zoom in and zoom out option (“zoom”)
of the analyzed image area;
o “near, far” – commands responsible for a manual setup of the focus of
registered image;
o “autof” – switching off the automatic image sharpness adjustment
(“auto focus”);
o “open, close” – commands responsible for manual opening/closure of
the shutter;
o “autoi” – switching off the automatic adjustment of the shutter
opening (“auto iris”).
2.10 The Module of the Digital Image Acquisition from
the Video Stream
During the experiments on the modules enabling communication and configuration
of the camera was created a module, which is necessary for the realization of the
objective task which was made for those researches. It concerns the possibility of
using the obtained video images for the synthesis and analysis of the processing and
