Parameter
Description
p/pan
Specifies the camera pan angle. "p" is a 1
°
unit, and "pan" is a 0.01
°
unit. For
example if the camera pans right 20
°
, then p is 20 and pan is 2000. If this
parameter is omitted, the camera pan angle is not controlled.
z/zoom
Specifies the camera tilt angle. "t" is a 1
°
unit, and "tilt" is a 0.01
°
unit. If this
parameter is omitted, the camera tilt angle is not controlled.
Specifies camera zoom. "z" is ten times the zoom ratio of the widest angle,
and "zoom" is the view angle in 0.01
°
units (horizontal direction. If this
parameter is omitted, camera zoom is not controlled.
Specifies camera backlight compensation. When this parameter is set to on, the picture
captured will be bright and when this parameter is set to off, the picture captured will be
dark. If this parameter is omitted, camera backlight compensation is not controlled.
b/back_light
camera_id
Assigns the numbers 1 to 4 to camera 1 to 4. If this parameter is omitted, the

t/tilt
delay
Waiting time until camera focus is stabilized (in milliseconds). Specified in the
range 0 to 10000.
seq
Allows any number (sequence number) to be specified to avoid displaying old
still pictures (numeric value).
v/image_size
Specifies the display size of the picture. Settings of 640 x 240, 320 x 240, and
160 x 120 are possible. Styles for v and image_size are different: For v, only
the horizontal size is specified, as in "v=640", for instance; while for
image_size, both horizontal and vertical sizes are specified, as in
"image_size=320x240", for instance.
q/quality
Specifies picture quality. Use an integer between 1 and 99. If omitted, the
value set in the VB101 is used.
option
Specifies how errors are dealt with. When "skip_on_error" is specified, the
process will be continued. When "quit_on_error" is specified, the process will
be aborted. The following errors can occur: failure to acquire camera control
right, loss of camera control, camera selection errors and camera control
errors. To omit, the default value is "quit_on_error".
Displaying Live Video from a Specified Angle
as Still Pictures
By specifying the camera angle as a parameter in the HTML code beforehand, you can display
the picture from a specified camera angle. The example below displays a still picture shot with the
camera panned right by 40° and tilted down 10°.
