5-25Creating Web PagesDistributing Videos Using a Browser OnlyDisplaying Live Video from a Specified Angle as Still PicturesBy specifying the camera angle as a parameter in the HTML code beforehand, you can displaythe picture from a specified camera angle. The example below displays a still picture shot with thecamera panned right by 40° and tilted down 10°. * The underlined portion is a sample IP address. Enter the actual IP address set for the VB-C10/VB-C10R.GetStillImage ParametersParameter Descriptionp/panSpecifies 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 thisparameter 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 thisparameter is omitted, the camera tilt angle is not controlled.z/zoomSpecifies 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 isomitted, camera zoom is not controlled.b/back_lightSpecifies camera backlight compensation. When this parameter is set to on, thepicture captured will be bright and when this parameter is set to off, the picturecaptured will be dark. If this parameter is omitted, camera backlight compensationis not controlled.delay Waiting time until camera focus is stabilized (in milliseconds).Specified in the range 0 to 10000.optionSpecifies how errors are dealt with. When “skip_on_error” is specified, the processwill 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 ofcamera control, camera selection errors and camera control errors. To omit, thedefault value is “quit_on_error”.seq Allows any number (sequence number) to be specified to avoid displaying oldstill pictures (numeric value).v/image_sizeS pecifies picture display size. This can be set to 640 × 480, 320 × 240, or 160 ×120. The formats for specifying “v” and “image_size” are different: “v” specifiesthe horizontal dimension only and uses the format “v=640”, for instance, while“image_size” specifies both horizontal and vertical dimensions and uses theformat “image_size=320 × 240”, for instance.q/quality Specifies the picture quality of the pictures. Use an integer between 1 and 99 tospecify. If omitted, the value set in the VB-C10/VB-C10R is used.NoteIf old still pictures are displayed, you can prevent this recurring by specifying asequence number in the seq parameter. |
