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°.

GetStillImage Parameters

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.

t/tilt

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.

z/zoom

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.

b/back_light

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.

delay

Waiting time until camera focus is stabilized (in milliseconds).

Specified in the range 0 to 10000.

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”.

seq

Allows any number (sequence number) to be specified to avoid displaying old

still pictures (numeric value).

v/image_size

S

pecifies picture display size. This can be set to 640

Ч 480, 320 Ч 240, or 160 ×

120. The formats for specifying “v” and “image_size” are different: “v” specifies
the horizontal dimension only and uses the format “v=640”, for instance, while
“image_size” specifies both horizontal and vertical dimensions and uses the
format “image_size=320

× 240”, for instance.

q/quality

Specifies the picture quality of the pictures. Use an integer between 1 and 99 to
specify. If omitted, the value set in the VB-C10/VB-C10R is used.

Note

If old still pictures are displayed, you can prevent this recurring by specifying a

sequence number in the seq parameter.
