Scanning speed adjusting method and scanning system

Abstract

The invention discloses a scanning speed adjusting method and a scanning system. The scanning speed adjusting method is suitable for an electronic device which comprises a scanning module and a controller, and at least comprises the following steps that: (a) the scanning module scans a file so as to generate image data; (b) the controller receives the image data and transmits the image data to anoutput device; and (c) the controller detects the input rate at which the image data is received by the scanning module and an output rate at which the image data is transmitted to the output device,and dynamically adjusts the scanning speed of the scanning module when the input rate is different from the output rate. Through the method and the system, the scanning speed can be increased to the optimal speed, so that scanning time is shortened and the optimal scanning and transmission efficiencies can be obtained.

Description

technical field [0001] The invention relates to a method for adjusting scanning speed, in particular to a method for adjusting scanning speed and a scanning system thereof. Background technique [0002] Multifunctional business machines are widely used because they can generate digital data representing the content of original manuscripts. These digital data are usually transmitted through input / output lines (I / Ocable) and stored on the host side, for example, data is transmitted by the multifunctional business machine side. to the computer side. The data transmission rate is related to the communication protocol used by the multi-functional business terminal and the host. Ideally, the rate of data transmitted to the host is the same as the rate that the host can receive. In this way, the scanning system does not need to have a memory buffer (memory buffer), whose function is to accumulate and store data to be transmitted. However, the speed of data generation is usually d...

Problems solved by technology

[0007] The main purpose of the present invention is to provide a method for adjusting the scanning speed and its scanning system, so as to solve the problem that the scanned image may be disturbed due to the shock of stopping and starting or the mechanical vibration during the process of suspending and restarting the scanning of the known scanning program. Gaps, which will cause the scanned image to shake or have other adverse effects at this position, which will reduce the scanning quality and other shortcomings
