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. | ||
| ||
| Specifies camera zoom. "z" is ten times the zoom ratio of the widest angle, | |
z/zoom | 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. | |
camera_id | Assigns the numbers 1 to 4 to camera 1 to 4. If this parameter is omitted, the | |
camera that is currently selected will be used. | ||
| ||
delay | Waiting time until camera focus is stabilized (in milliseconds). Specified in the | |
range 0 to 10000. | ||
| ||
|
| |
| Specifies how errors are dealt with. When "skip_on_error" is specified, the | |
option | 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). | ||
| ||
|
| |
| 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 | |
v/image_size | 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. | ||
| ||
|
|
c | If old still pictures are displayed, you can prevent this recurring by specifying |
Note | a sequence number in the seq parameter. |
