Abstract
A control device and a method for controlling scanning speed of a scanner. The control device includes a decision device and a driving device. The decision device further includes an image buffer, an up-down counter and a comparator. The decision device receives the input image data and utilizes the up-down counter to compute data access volume inside the image buffer. The comparator decides whether to increase or decrease the scanning speed according to the data access volume and also outputs decision data to the driving device.
Claims29
1-11. (canceled)
An apparatus, comprising:
- a first device configured to select a scanning speed value from a plurality of predetermined scanning speed values based at least on an amount of image data to be generated during a scanning operation;
- and
- a second device configured to control a scanning speed of a scanner based on the scanning speed value.
A tangible computer-readable medium comprising executable instructions that, in response to execution by a computing device, cause the computing device to:
- receive a signal associated with an amount of data to be generated during a scanning operation;
- select a scanning speed value from a plurality of predetermined scanning speed values based at least on the amount of data to be generated during the scanning operation;
- and
- control a scanning speed of a scanning operation based at least on the scanning speed value.
An apparatus, comprising:
- means for identifying an approximate amount of data to be scanned in a scanning operation, wherein the approximate amount of data corresponds with a document that is at least partially un-scanned;
- means for selecting a scanning speed value from a plurality of scanning speed values based at least on the approximate amount of data;
- and
- means for controlling a scanning speed of a scanning operation based at least on the scanning speed value.
An apparatus, comprising:
- a logic circuit configured to:
- receive an input signal corresponding with an amount of data expected in a subsequent scanning operation;
- select a scanning speed value from a plurality of predetermined scanning speed values based at least on the input signal;
- and
- control a scanning operation based at least on the scanning speed value.
