The Device type exposes the following members.
Properties
| Name | Description | |
|---|---|---|
 | ExposureTime |
Specifies the exposure time used to capture the image, in seconds.
ICAP_EXPOSURETIME
|
| FlashUsed2 |
For devices that support flash. MSG_SET selects the flash to be used (if any). MSG_GET reports the
current setting.This capability replaces ICAP_FLASHUSED, which is only able to negotiate the
flash being on or off.
ICAP_FLASHUSED2
|
| ImageFilter |
For devices that support image enhancement filtering. This capability selects the algorithm used
to improve the quality of the image.
ICAP_IMAGEFILTER
|
| LampState |
TRUE means the lamp is currently, or should be set to ON.Sources may not support MSG_SET
operations.
ICAP_LAMPSTATE
|
| LightPath |
Describes whether the image was captured transmissively or reflectively.
ICAP_LIGHTPATH
|
| LightSource |
Describes the general color characteristic of the light source used to acquire the image.
ICAP_LIGHTSOURCE
|
| MinimumHeight |
Allows the source to define the minimum height (Y-axis) that the source can acquire (measured in units of
Unit).
This is a read only capability.
ICAP_MINIMUMHEIGHT
|
| MinimumWidth |
Allows the source to define the minimum width (X-axis) that the source can acquire (measured in units of
Unit).
This is a read only capability.
ICAP_MINIMUMWIDTH
|
| NoiseFilter |
For devices that support noise filtering, selects the algorithm to be used.
ICAP_NOISEFILTER
|
| Online |
If true, the physical hardware (e.g., scanner, digital camera, image database, etc.) that represents
the image source is attached, powered on, and communicating.
CAP_DEVICEONLINE
|
| OverScan |
Overscan is used to scan outside of the boundaries described by ICAP_FRAMES, and is used to
help acquire image data that may be lost because of skewing.
ICAP_OVERSCAN
|
| PhysicalHeight |
The maximum physical height (Y-axis) the Source can acquire (measured in units of
Unit).
ICAP_PHYSICALHEIGHT
|
| PhysicalWidth |
The maximum physical width (X-axis) the Source can acquire (measured in units of
Unit).
ICAP_PHYSICALWIDTH.
|
| SerialNumber |
A string containing the serial number of the currently selected device in the Source. Multiple
devices may all report the same serial number.
CAP_SERIALNUMBER
|
| TimeDate |
The date and time of the device’s clock.
Managed in the form “YYYY/MM/DD HH:mm:SS:sss”
CAP_DEVICETIMEDATE
|
| Unit |
Unless a quantity is dimensionless or uses a specified unit of measure, This setting determines
the unit of measure for all quantities.
ICAP_UNITS
|
| ZoomFactor |
Camera lens zooming.
ICAP_ZOOMFACTOR
|
