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.

Description

V. Description of the Invention (Jade) 5-1 Field of the Invention The present invention relates to a = otherwise-a method and a scanning system relating to the speed of scanning: the system clock, the sequence of changing the transmission rate, and Method and scanning system. 5-2. Background of the Invention: Knowing and describing the general application of cable) to computer. The communication rate is the same as that of the receiving speed. However, 0 is therefore the tracing effect because. These send and store information is relevant. All the data sent by the host are different. The fastest scanner, when the phase of the transmission rate can be generated, the original digital data is usually stored on the host side. For example, the transmission rate and the scan rate are ideally the transmission rate phase buffer (memory data. However, if the data is transmitted, The data is generated at a high speed, and the data is generated at a lower speed than the data production problem. The digital data of the manuscript content is widely transmitted through the input / output lines such as the data from the scanner to the sender and the host. The generation of data to the host is the same. In this way, the scanning system buffer), its function is that the cumulative generation speed is usually the same as the data generation rate of the host. Speed, it often causes scanning in addition to optical resolution. The scanning speed is

556434 V. Description of the invention (2) = Requirements of the device function. Scanning speed is defined as the transmission from scanning: ί ;; 所;:! :: The time when the data is expected to be transmitted to the host. It is possible that after scanning only a part of the original, tiredness and punching will result in full; To avoid loss of data due to memory buffer filling, the scanning process is usually paused first. After the sound, the loss of the poor material is completed or there is room to accommodate other data: slow = data complete process. In other words, when the buffer is full = start scanning = pause the scan first, and then move backward a few steps vs. the scanning mode to avoid scanning instability due to mechanical inertia, which will affect the scan a few steps after the restart. quality. After moving 2 modules at the beginning of the first body transfer to the host, the scan module will open another two accumulation and buffer = then you can avoid the "data" of the image data. This starts / pauses the program and lengthens the scanning time. In order to continuously repeat the process of backing the scanning module to a fixed value or pausing the scanning module and then just starting to move, start the scanning program "Cacheng; generally called star stop"). This program also ^ starts / pauses the program (in the sequence, thereby reducing the scanning speed.) ^ Tian Yi's forward and backward development has developed many methods to solve the problem, move / pause, outside the program, the transmission rate The problem on the computer. And :: Two different _______ ^ Valley I makes scanning $ 6 pages 556434 5. Description of the invention (3) _____ Toda program is not limited to the computer method. But increase the buffer capacity == "Directly, and most = points. That is to say, it will increase the manufacturing cost; there is indeed ^ complexity on S. Furthermore, when the design of high-resolution = pay = device is more powerful: a large amount of image resources will be generated in the interim. : Two in a very short: capacity, is not a feasible way =. Only when the buffer area is enlarged early, long, long; trace = degree can not only shorten the scanning original large buffer area i:; = 1 : Wen rate. Therefore, the development-a method that does not require the addition / pause area to fill up, reduces the method of starting the scanning system, which can increase the scanning speed, and the purpose and overview of the invention of 5-3. η =: The scanning method and the scanning system transmission rate adjustment are the key points of the present invention. Corresponds to the rapid transmission of variable data on the transmission interface; quickly, adjust the system clock to reduce the memory buffer i ”: f Increase the buffer capacity, you can reach the private sequence time, and then increase the scanning speed. Good fee Start / Pause 556434 V. Description of the invention (4) Another object of the present invention is to generate a scan / start method for the start / pause program to avoid the field method and scanning system during the scanning process. Another object of the present invention is to By adjusting the system clock, changing the time y and the transmission interface, the system is based on the scanning method and scanning. Another object of the present invention is to increase the scanning speed without the need to increase the capacity of the scanning area. Method and scanning system for memory slowdown. According to the above-mentioned purpose, in a method based on a transmission interface, the present invention provides a transmission rate of an interrupted transmission interface. For example, at least one step includes: A system clock to change the transmission rate of the data generation rate, adjust the material generation rate to generate a data, and the data generation K to trace an original, depending on the rate: clever rate. And adjust The steps of the system clock: Yes: how to reduce the frequency of the spoken speed T 1 The frequency multiplier generated by the clock generator 2 contains' based on transmission J: selected by many preset values. The method of the present invention: t 丄 its: multiple input "Quoting data from the scanning system to the host: J contains, increasing the scanning rate through the transmission speed" Comparison of the transmission rate and the forecast; the value; the transmission speed of the 3 transmission surface can be lost. The rate is not the same as the preset value. Page 8 556434 V. Description of the invention (6) And: = The above-mentioned invention can also be widely implemented in other embodiments. The scope of the specification is not limited, and the following patent scope is The scanning system is known to be optimized differently when scanning the system. When the speed is full, the waste is reduced. The scanning speed is based on transmission to avoid the scanning system using fixed pulses and fixed scanning methods. However, the transmission interface in other words, when ’or when it is short, the optimization of start / pause cannot be avoided. The comprehensive transmission interface adjusts the fixed cycle ratio of the motion / pause program (duty rate generates data, and at a fixed rate, the rate of output varies, and the data generation rate time generates a large number of motion / pause program procedures. Because of the previous technology, Lack of the system clock makes it reach the scan speed cycle) and the data generated by the previous technology and achieve the scan. The data of the transmission interface makes it happen. At the same time, it is not possible. The speed of the transmission buffer can not be achieved to provide a method for optimizing the generation rate of data and one of the key points of the present invention is that the transmission speed of the transmission interface based on the same: two-sided transmission rate Do not generate the rate, but avoid starting / temporary, different, to determine the asset; the other another-emphasis is the use of the adjustment system: the possibility of order. The purpose of the material production rate. As a means to achieve change: Referring to the first figure, a simplified block diagram of a system 100 is described by one of the present invention. In the examples only, a book is provided

The system 100 includes at least the clock J. V. Description of the invention (8) = The time-tracing module 130 will _ iiSR 丨 and generate a fir-like beke. For example, if the transport interface is. That is, the clock frequency of the box fish r 4 'system is 2 and 3 times, respectively, the rate (F) is 2 and 3 times, the transmission interface is 2.1 and the system clock frequency of IEEE1 394. Respectively. "Therefore, there is less chance of the image data buffer to fill up, and the time delay is delayed, so as to achieve the optimal speed of the women's tracing speed.

For example, the transmission speed is used and the transmission speed is broken. When I, the transmission rate can also be determined at the same time: this: 偯 :: the transmission interface speed Mblt / sec is at ^^ dedicated transmission speed / yes, Does Mbit / sec or timing generate a message? Lu Yi enters $ 丨 _ 刖 and is scanning the system initialization process, or ί = ::: Scan to determine the type of transmission interface or transmission rate. Flrmware detection and transmission In step 220, according to the transmission wheel, the scanning module is suppressed by the frequency of the system clock; ^ " the system clock. That is, data is generated at the rate at which the area is filled. Second, the next two idiots, to avoid the transmission rate of the memory slow interface, the frequency adjustment of the clock to generate the t pulse is based on the number. For example, the USB transmission wheel ^ is a frequency doubled by one frequency; 1 has two transmission rates, high speed (556434 V. 480 intestines of the invention description (9)… full speed (fuU S_d)- ^ τ # I, ^ „0, Μ ^ ΐ ^ I;: P; ed) 0 is also determined at the same time. When the transmission interface has multiples of frequency multiplication) For example, delete 1 394, EPP, and SCSI, d = rate When the maximum frequency reached by the example is used, the rate of pulse can reach far faster than the rate that the data can produce. When; = =, its transfer time is ‘for example USB1.1. The data is to avoid memory 2: J has a lower transmission rate and generates data. , Bamboo House Health Rate, Scan Originals In addition, the flowchart. Judging the scanning range 1 50 a. Yu step whole or not, yes. When the transmission speed is more detailed and fast, the clock speed of the transmission system is small and the rate is small. Then generate data. The second diagram B is the steps of the method for improving the present invention. The steps are as follows: Λ embodiment = two Λ interfaces. For example, the transmission interface described in step 240. Never adjust the system clock according to the transmission interface. The modulation rate of the first h-pulse is not equal to the pre-::: loser rate compared with the preset value. According to the comparison, in step 250, the system clock is adjusted to accelerate the data generation. "People in Pre-duty Day" when adjusted to the preset value, ancient Zhou _ 糸 士 士 之, when the transmission interface at step 260, scan the original, low-key 枓, draft, and control based on the system's clock To apply the scanning program of the present invention, first determine the transmission interface 15 page 13 of page 556434. 5. Description of the invention (ίο) The transmission rate, for example, using the USB1 · 1 1 transmission interface. When the optical detector i 6〇 such as charge coupling Component ((CCD), scans the original to generate analog data. Then the analog / digital conversion device 170 converts the analog image data to digital image, 1 material. Then, the image processing device of the scanning module, according to the corresponding system, first The clock generates data. The frequency of the system clock is generated by a frequency doubling device such as phase locked == (PLL). The frequency (F) of the clock generator is multiplied by a multiple (for example, such as the one used in this example). 2F. Therefore, change the data to generate ^, to avoid the wasting of the memory buffer device 丨 4 〇, and reduce the waste of time in the startup, temporary τ program. Without increasing the memory buffer to achieve increased scanning speed The purpose.
