still.jpg parameters

Command

Description

camera_id

Specifies the camera when you switch between cameras. 1 is this camera, and

2 is an external camera. When there is no specification, you are deemed to

have specified the current camera.

z or zoom

Specifies the zoom magnification of the camera. z is ten times zoom magnification

of maximum wide angle and zoom is in units of 0.01˚.

b or 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.

v or image_size

Specifies image size. You can specify 160

Ч 120, 320 Ч 240, and 640 × 480 for

NTSC, and 192

Ч 144, 384 Ч 288, and 768 × 576 for PAL. The format for v and

image_size is different. v only specifies horizontal size, e.g. v=640. image_size

specifies vertical and horizontal size, e.g. image_size=320

× 240.

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”.

Tip

Specifying with the current position which appears as “d” and the percentage for the

current angle which appears as “c” (percentage) is also possible for z (zoom).

For example:

z=c200 sets twice the current zoom magnification.
