Abstract
A scanner includes a first illuminant device having a first power associated therewith, and a second illuminant device having a second power associated therewith. The first power is greater than the second power, and each of the first illuminant device and the second illuminant device is configured to selectively scan a document. The scanner is configured to select one of the first illuminant device and the second illuminant device based, at least in part on, a level of power supplied to the scanner via a power source, and perform a single scan of the document using only the selected one of the first illuminant device and the second illuminant device.
Claims20
A scanner comprising:
- a first illuminant device having a first power associated therewith;
- and
- a second illuminant device having a second power associated therewith, wherein the first power is greater than the second power, and each of the first illuminant device and the second illuminant device is configured to selectively scan a document, wherein the scanner is configured to:
- select one of the first illuminant device and the second illuminant device based, at least in part, on a level of power supplied to the scanner via a power source;
- and
- perform a single scan of the document using only the selected one of the first illuminant device and the second illuminant device.
A method, comprising:
- detecting a level of power supplied to a scanner, wherein a first level of power is associated with a first illuminant device, and wherein a second level of power is associated with a second illuminant device, each of the first illuminant device and the second illuminant device is configured to selectively scan a document;
- selecting one of the first illuminant device and the second illuminant device based, at least in part, on the level of power supplied to the scanner;
- and
- performing a single scan of the document using only the selected one of the first illuminant device and the second illuminant device.
An apparatus, comprising:
- means for determining a level of power supplied to a scanner, wherein a first level of power is associated with a first illuminant setting, and wherein a second level of power is associated with a second illuminant setting, each of the first illuminant setting and the second illuminant setting for selectively scanning a document;
- means for selecting one of the first illuminant setting and the second illuminant setting based, at least in part, on the level of power supplied to the scanner;
- and
- means for performing a single scan of the document using only the selected one of the first illuminant setting and the second illuminant setting.
