Description of the invention (multi) Document width; (b) Drive the image capture device from the starting position by the driving device Move backward to the color correction plate to perform a color correction action; and (c) drive the image capture device to move forward from the position of the color correction plate with the driving device, and perform according to the obtained width of the document to be scanned An image scanning action can save a scanning time. According to the above idea, in the image scanning method, the image scanning operation is based on the obtained width of the document to be scanned, so that the image capture device only accesses and transmits digital data within the width of the document to be scanned. According to the above conception, in the color correction operation performed in step (b) of the image scanning method, the image capturing device is located only within the width range of the document to be scanned according to the obtained document width to be scanned. The pixel points are corrected to obtain a function of saving correction time. According to the above-mentioned concept, the step t of the width detection operation performed on the document to be scanned in step (a) of the image scanning method further includes a step of setting a contrast between the document to be scanned and the color where it is placed.

Description of the invention (4) The third figure: it is a block diagram of the structure of the image scanner used in the method of the preferred embodiment of the present case. Figure 4: A flowchart of the steps of the method of the preferred embodiment of the present case. The components included in the drawings of this case are listed below: Image capture device 11 Scanning platform 13 To scan documents 15 Image capture device 31 Scanning platform 33 To scan documents 3 5 Drive device 12 Color correction plate 14 Lifting line 16 Drive Device 32 Color correction plate 34 Starting position line 36 (Please read the precautions on the back before filling this page) The preferred embodiment is printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economics. Please refer to the third zero, which is better in this case In the embodiment, the square block diagram of the structure of the image scanner is used. The image capture device 31 is used to capture the image of the document 35 to be scanned and converted into a digital data for processing. The drive device 32 is used to drive The image capturing device performs a scanning operation, and a color correction plate 34 is also provided on the upper side of the scanning platform 33 on which the document 35 is to be scanned. The starting position line 36 where the image capturing device 31 is parked before scanning can be set. Between the to-be-scanned document 35 and the color correction plate 34, the scanning length can be shortened, but the latter is set closer to the to-be-scanned document 35 near the color correction. Part 6 of 34 Please refer to the fourth Seoul again, which is a flowchart of the steps of the method of the preferred embodiment of this case. Since the starting position of the image capturing device 31 parked before scanning, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (2ί297 × 297 mm) Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs M0120 5. Description of the invention (f) = It is located in the part of the document to be scanned near the color correction plate 34, so when the image scanning device should be used Immediately after the trigger, the image capture device 31 immediately performs a width detection operation on the document to be scanned 35, thereby obtaining the width W of the document to be scanned. Taking reflective scanning as an example, the document 35 to be scanned is set to have a contrast with the hidden color where it is placed. The image capture device 3 \ performs a one-line scan on the image obtained. The reflected light of the received image will be reflected in the document and There is a brightness difference between the backgrounds, so the width of the document 35 to be scanned can be easily obtained. In the same way, this case can also be applied to penetrating scanning. It is only necessary to set the penetrating rate of the document 35 to be scanned and the place where Mo is placed. 'π When the width of the document 35 to be scanned is detected, the driving device 32 is taken, and the image capturing device 31 is moved backward from the starting position wheel to the color = positive plate 34 to perform a color correction operation. The purpose is described in the background of the technique, and according to the color correction action of the === line that has been obtained, only the pixels located outside the width W of the document to be traced can be located in the document to save the correction time. Effect. W Park Jung, in this way, once the color correction operation is completed, the image capture device 31 is used by the color correction plate position device 32 to drive the image scanning file 35 image scanning operation, and the root is moved to perform the alignment The desired device 31 can access and transmit only the selected:; == the mysterious materials of the 敫 Jun domain within the width W of the document to be scanned. 6 This paper size applies the Chinese National Standard (CNS) a4 specification ( 210X297 mm) (Please read the notes on the back before filling this page)

Description of the invention (厶) (Please read the precautions on the back before filling in this page) The digital data that is located outside the W width of the document to be scanned is accessed and transmitted, so you can get a f The effect of saving scan time. When performing a formal scanning action, it is necessary to determine whether the document has been scanned to the bottom of the document. (Because the document 35 to be scanned has a contrast with the color where it is placed, it can be easily detected when scanning beyond the L range of the scanned document Measured), if otherwise the scanning is continued, and if it is completed for the holding motion, the image capturing device 31 is moved back to the starting position line 36 in order to wait for the next sweep operation. As mentioned above, the method in this case is to set the starting position line 36 of the image capture device 31 parked before scanning on the part of the document to be scanned close to the color calibration JL board 34. This not only shortens the length of the scanning device. Without pre-scanning, you can know the width of the document to be scanned in advance. In the color correction and scanning, you only need to correct and access the data within the width range of the document to be scanned. The time required for acquisition and scanning is the main purpose of the case. The creation of this case must be modified by anyone who is familiar with this technology, but it is not as good as the attached patent application. It belongs to the protector. 0 Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. Lemon standard (CNS) A4 specification (210X 297 mm)
