    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.

    Abstract: An accumulation unit accumulates, in a 1-line element corresponding to the main scanning direction, an electrical signal prepared by photoelectrically converting optical image information obtained by scanning an original image to be formed with a carriage in the subscanning direction. A magnification setting unit sets the copy magnification. A speed change unit changes the moving speed of the carriage in accordance with the copy magnification, and when the set copy magnification is equal to or smaller than a certain magnification in reduction, changes the carriage moving speed to 1/n (n: a natural number larger than 1) from the relationship between the current magnification and the carriage moving speed. A preprocessing unit converts the electrical signal into a digital signal, has a line memory for storing 1-line input image data in the main scanning direction, performs arithmetic processing for multilevel n-line data in the main scanning direction to change the subscanning magnification in reduction, and outputs 1-line output image data in the main scanning direction. An image data processing unit performs predetermined image data processing including processing of receiving for each pixel the 1-line output image data in the main scanning direction output from the preprocessing unit, and converting the image data into binary data.
