Displaying Live Video from a Specified Zoom Magnification as Still Pictures
By specifying the camera zoom magnification as a parameter in the HTML code beforehand, you can display the picture from a specified camera zoom magnification. The example below displays a still picture shot with the camera panned right by 40° and tilted down 10°.

GetStillImage Parameters
Parameter | Description | |
| Specifies camera zoom. “z” is ten times the zoom ratio of the widest angle, and | |
z or zoom | “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 | |
b or back_light | 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. | ||
| ||
| 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. | |
option | 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 picture display size. This can be set to 160 ⋅ 120, 320 ⋅ 240, and 640 | |
v or image_size | ⋅ 480 for NTSC, and 192 ⋅ 144, 384 ⋅ 288, and 768 ⋅ 576 for PAL. 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. | |

Note
If old still pictures are displayed, you can prevent this recurring by specifying a
sequence number in the seq parameter.
