Abstract: In a method and an apparatus for forming image, digital image information is generated by conveying a document and scanning an image recorded on the document while conveying the document. When an image is scanned with a high resolution that is greater than a default resolution, a document is conveyed at a default speed at an initial stage and the document is conveyed at a speed slower than the default speed during an image scanning operation. The image forming apparatus includes a scan unit scanning the image recorded on the document, and a conveying unit which conveys the document at a default speed in an initial stage of conveying the document, and which conveys the document at a speed slower than the default speed while scanning the image in a high resolution scanning operation that has higher resolution than a default resolution.

Abstract: An image scanning apparatus is capable of successively scanning a plurality of documents arranged on a document plate in an efficient manner by moving a sensor unit over the documents in a sub-scanning direction. When the plurality of documents arranged on the document plate is scanned, the motion of the sensor unit is selectively controlled in such a manner that after completion of scanning one document, the sensor unit is returned to its home position before starting scanning a next document, the sensor unit is temporarily stopped before starting scanning the next document, or the sensor unit is moved backward by a particular distance before starting scanning the next document.

Abstract: In accordance with the present invention, a method and a system for promoting scanning speed are provided. The method comprises steps of determining a transmission rate of a transit interface, adjusting system clock responsive to the transmission rate of the transit interface to change a data generated rate, and scanning an original to generate data at the rate controlled by the system clock. The key aspect of the present invention is by adjusting system clock to change the data generated rate corresponding to the transmission rate of the transit interface. Therefore, in response to the transmission rate of the transit interface, the system clock is adjusted to produce the data at a rate that can reduce the possibility of memory buffer full leading to the reduction in the time wasting on start-stop processes and therefore promote the scanning speed without requiring the increase in size of a memory buffer.
