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.
