玖、發明說明 (發明說明應敘明：發明所屬之技術領域、先前技術、內容、實 施方式及圖式簡單說明） 本發明是有關於一種掃描器的運作方法，且特別是有 關於一種掃描器之多次無方向性掃描方法。 由於電腦技術的日新月異，多媒體的發展，電腦已慢 慢地成爲現代人日常生活中不可或缺的必需品，而影像處 理的進展一日千里，帶動許多電腦周邊影像處理器的進 步，掃描器即是一例，在短短的數年之間，由掌上型黑白 掃描器到現在全彩高解析度的掃描器，其所產生的影像更 加精緻更加逼真。 請參照第1圖，其所繪示爲習知掃描器的外觀繪示圖。 依照掃描器的外觀，可將之區分爲，覆蓋板10與機殼， 而機殼又可分爲，上部外殼20與下部外殼30，在上部外 殼20上有一片透光玻璃40，掃描文件則置於覆蓋板10以 及上部外殼20之間，當掃描器開始掃描文件時’掃描文 件影像則會經由透光玻璃40，進入掃描器內並由載具 (Chassis)接收掃描文件，而在載具中有光學感側元件以 及成相系統用來完成掃描文件之影像。 請參照第2A圖，其所繪示爲習知掃描器內上部外殼 的繪示圖。在機殼內部，上部外殼20的內面’架構有一 個校正尺60,此校正尺60的作用即是讓載具再開始掃描 之前，先做一次光學黑（Optical Black)以及參考白（white Chart)的校正，並依照校正的結果，來達成掃描文件中顏 08446twfl.doc 4 548953 坡· 3· 年月 色的辨認。如第2Β圖所繪示，校正尺60有二個顏色區域， 亦即光學黑區域64以及參考白區域62。 請參照第3圖，其所繪示爲習知掃描器的運作流程繪 示圖。當使用者在操作習知的掃描器時，在掃描文件置入 掃描器後，首先，掃描器必須先作校正（Calibration) 70， 接著，使用者可以設定掃描參數（Set Scan Parameter ) 80， 掃描參數設定80完成之後，驅動掃描器內的載具 (Chassis)至文件處並開始掃描，進而獲得影像90 (Get Image)，當掃描的動作完成之後，由於載具已經移動到掃 描器的另一邊，所以必須驅動馬達將載具帶回校正尺的位 置，所以此動作即是將載具歸位（Park Home) 100，即完 成一次的掃描動作，並等待下一次的掃描。 當掃描器必須掃描多份文件掃描或者作批次掃描時， 如同上述習知掃描器的運作流程，而每一次的文件掃描， 掃描器都必須先經過校正70、設定掃描參數80、取得影 像90以及歸位1〇〇的步驟，對於載具的運動來說非常的 耗費時間。 有鑑於此，本發明利用程式控制掃描方向，可根據使 用者所下達的參數，作最有效率的來回掃描運作，包括批 次掃描、預覽及掃描動作一次來回即可完成或者利用低解 析度的來回掃描運作，達成高解析度的全彩掃描。此外， 運用本發明’掃描器可以不產生歸位的動作，而直接準備 作下一次的影像掃描，因此可在一定的時間內，產生較多 次的影像取得。 08446twfl .doc 5 本發明提出一種掃描器之多次無方向性掃描方法。首 先’由掃描文件之一端對掃描文件進行預覽掃描，並根據 分析所得之預覽影像以設定掃描參數。之後則由此掃描文 件之另一端以所設定之掃描參數反向進行掃描，取得最終 掃描影像。 本發明另外提出一種掃描器之多次無方向性掃描方 法。本方法首先於載具前進時取得第一部分影像。之後， 再於載具後退時取得與第一部份影像不重疊的第二部分影 像。最後則結合第一部分影像與第二部分影像以取得最終 掃描影像。 本發明還提出一種掃描器之多次無方向性掃描方法， 其適用於分別掃描數個部分文件的掃描過程中。此多次無 方向性掃描方法首先掃描這些部分文件的其中之一份部分 文件。而在掃描此部分文件結束後，再判斷是否要繼續進 行掃描。而當需要繼續掃描時，再判斷是以正向掃描或反 向掃描之方法來繼續進行下一個部分文件的掃描。 爲讓本發明之上述目的、特徵、和優點能更明顯易懂’ 下文特舉較佳實施例，並配合所附圖式，作詳細說明如下： 圖式之簡單說明： 第1圖所繪示爲習知掃描器的外觀繪示圖； 第2A圖所繪示爲習知掃描器內上部外殼的繪示圖； 第2B圖所繪示爲校正尺； 第3圖所繪示爲習知掃描器的運作流程繪示圖； 第4圖所繪示爲根據本發明之一較佳實施例的運作流 08446twfl.doc 6 548953发明 Description of the invention (the description of the invention should state: the technical field to which the invention belongs, the prior art, the content, the embodiments and the simple description of the drawings). Multiple non-directional scanning methods. Due to the rapid development of computer technology and the development of multimedia, computers have gradually become an indispensable necessity in the daily life of modern people, and the advancement of image processing has driven the progress of many image processing processors around computers. Scanners are an example. In just a few years, from palm-type black and white scanners to today's full-color high-resolution scanners, the images they produce are more refined and more realistic. Please refer to FIG. 1, which is a drawing showing the appearance of a conventional scanner. According to the appearance of the scanner, it can be divided into a cover plate 10 and a case, and the case can be divided into an upper case 20 and a lower case 30. On the upper case 20, there is a piece of transparent glass 40. It is placed between the cover plate 10 and the upper casing 20. When the scanner starts to scan the document, the scanned document image will enter the scanner through the transparent glass 40, and the scanned document will be received by the carrier. There are optical sensor-side elements and phase-forming system to complete the image of scanning the document. Please refer to FIG. 2A, which is a drawing showing the upper casing of a conventional scanner. Inside the casing, the inner surface of the upper casing 20 has a calibration ruler 60. The function of the calibration ruler 60 is to make the optical black (Optical Black) and the reference white (White Chart) before the carrier starts to scan again. ), And according to the results of the correction, to achieve the recognition of the color in the scan file 08446twfl.doc 4 548953 slope. As shown in FIG. 2B, the correction ruler 60 has two color regions, that is, an optical black region 64 and a reference white region 62. Please refer to FIG. 3, which is a diagram showing the operation flow of the conventional scanner. When the user is operating a conventional scanner, after the scanned document is placed in the scanner, the scanner must first perform Calibration 70, and then the user can set the Scan Parameter 80 to scan After parameter setting 80 is completed, the vehicle (Chassis) in the scanner is driven to the document and scanning is started to obtain an image 90 (Get Image). When the scanning operation is completed, the vehicle has moved to the other side of the scanner. Therefore, the motor must be driven to bring the carrier back to the position of the calibration ruler, so this action is to return the carrier to the Home (Park Home) 100, that is, to complete one scanning operation and wait for the next scanning. When the scanner must scan multiple documents or perform batch scanning, the operation process of the conventional scanner is the same as above. For each document scan, the scanner must first undergo calibration 70, set scanning parameters 80, and obtain images 90. And the step of returning to 100 is very time consuming for the movement of the vehicle. In view of this, the present invention uses a program to control the scanning direction, and can perform the most efficient back-and-forth scanning operation according to the parameters issued by the user, including batch scanning, previewing and scanning operations can be completed in one go or using low-resolution Scan back and forth to achieve high-resolution full-color scanning. In addition, by using the scanner of the present invention, it is possible to directly prepare for the next image scanning without generating a return operation, and therefore, a plurality of image acquisitions can be generated within a certain period of time. 08446twfl .doc 5 The present invention proposes a multi-directional non-directional scanning method for a scanner. First, a scan of the scanned file is performed from one end of the scanned file, and the scan parameters are set based on the preview image obtained by analysis. Then, the other end of the scanned file is scanned in reverse with the set scanning parameters to obtain the final scanned image. The invention also proposes a multiple-direction non-directional scanning method of the scanner. This method first obtains the first part of the image when the vehicle is moving forward. After that, the second part of the image that does not overlap with the first part of the image is obtained when the vehicle moves backward. Finally, the first image and the second image are combined to obtain a final scanned image. The invention also provides a multiple-direction non-directional scanning method of the scanner, which is suitable for the scanning process of scanning several partial files respectively. This multiple non-directional scanning method first scans one of these partial files. After scanning this part of the file, determine whether to continue scanning. When it is necessary to continue scanning, it is judged that the forward scanning or reverse scanning method is used to continue the scanning of the next partial file. In order to make the above-mentioned objects, features, and advantages of the present invention more obvious and easy to understand, hereinafter, the preferred embodiments are described in detail with the accompanying drawings as follows: Brief description of the drawings: Figure 2 shows the appearance of the conventional scanner; Figure 2A shows the internal casing of the conventional scanner; Figure 2B shows the calibration ruler; Figure 3 shows the conventional scan.

Since the conventional scanner must return to its original position after scanning, and make another correction before the next scanning, this When scanning a large number of files, it is a waste of time, and 7 08446twfl.doc has been experimentally obtained. When performing multiple corrections when scanning multiple files, the correction parameters have hardly changed. The corrective action for each scan is superfluous. Since the correcting action can be omitted, the vehicle does not need to return to the home position for calibration. Therefore, regardless of the direction the vehicle is traveling, you can scan the image. Please refer to FIG. 4, which shows a flowchart of the operation according to a preferred embodiment of the present invention. In this embodiment, first perform a preview scan operation on the document from one end of the document to be scanned, and analyze the image obtained by the preview scan at the same time as the preview scan to obtain the scan parameters required for subsequent scans (step S4. 0). After the scan parameters are determined (step S410), the document is scanned from the other end of the file with the scan parameters (step S42), and the final scan image is obtained by this scan (step S430). Using this embodiment, when the scanner has a preview function, the scanner can perform a preview operation when the vehicle is driven forward and analyze the scanning parameters required for subsequent scanning. When the vehicle moves in the opposite direction, ‘final scan’ can be performed, so that the vehicle can complete the scanning action once and for all. Please refer to Fig. 5, which shows an operation flowchart according to another preferred embodiment of the present invention. In this embodiment, the vehicle is first taken to take a part of the image of the younger brother while keeping the file forward (step S500); the next folder is stored, and the previously obtained first part is stored in step S520. The image is synthesized with the second part of the image to obtain the final scanned image. 08446twfl.doc 8 548953
必須注意的是，在本實施例中所取得的第一部分影f象 與第二部分影像若要達成以最少資料量完成掃描的目的， 則第一部分影像與第二部分影像就以不互相重疊爲原則， 否則第一部分影像與第二部分影像的取得並無任何限制。 而當限定第一部分影像與第二部分影像不互相重疊時，舉 例來說，可以以線上每隔一點取影像，或每隔一線來取得 影像，但是並不以此爲限。也就是說，可以在載具前進時 取得線上單數點或雙數點的影像而形成第一部分影像，而 在載具後退時，則相對取得線上雙數點或單數點的影像而 形成第二部分影像。或者，當載具前進時，取得單數線或 雙數線爲第一部分影像，而當載具後退時則相對取得雙數 線或單數線爲第二部分影像。 當然，第一部分影像與第二部分影像取得的限制並非 僅能如上所述的相隔一點。只要能以上述的方法來取得影 像，則無論是間隔多少點或線，都可以爲本發明所使用。 而本實施例的優點在於，當掃描文件要做全彩的掃描時， 在習知的處理上，掃描會耗費非常多的時間。而利用本發 明則可以省去許多的時間。舉例來說，掃描器在做全彩 600dpi解析度掃描時，載具在前進時，即可選取單數點來 作300dpi解析度的掃描，而載具在反方向前進時，可選 取雙數點來作300dpi解析度的掃描，因此結合此二個圖 形，即可達成全彩600dpi的解析度，並且可以節省習知 直接掃描全彩600dpi解析度一半以上的時間。 請參照第6圖，其顯75的是根據本發明之又一較佳實 08446twfl .doc 9 548953 貌略 ；；-& … ： -病: 施例的運作流程圖。本實施例適用於在批次掃描，也就是， 當有多份部分文件需要分批掃描的時候。在本實施例中， 首先取得一份部分文件的掃描影像（步驟S600)。之後則在 步驟S610之中判斷是否繼續進行掃描。當不需繼續進行 掃描時’則結束；而若還有任何部分文件正在等待掃描， 則根據當時的狀況，由程式來判斷是要做正向或反向掃描 (步驟S620)。當決定以正向或反向掃描來處理下一份部分 文件之後，程式就會驅動載具到達下一份部分文件所在的 地方，以所決定的掃描方式進行步驟S600來取得此部分 文件的掃描影像。 由於在習知技術中，當多個掃描文件同時置於掃描器 窗口（Window)內要做批次掃描時，載具在每一次的掃 描文件處理後都必須歸位，重新校正後再繼續掃描。舉例 來說，當透光玻璃上同時置入二個掃描文件時，依照習知 掃描器的做法，載具在做完校正後，驅動載具至第一個掃 描文件處並開始掃描，獲得影像後，載具必須歸位，並再 驅動載具至第二個掃描文件處開始掃描，獲得影像後，載 具歸位。如此，載具爲了校正必須來回移動二次非常的不 方便。而本實施例則在掃描第一個掃描文件獲得影像後， 直接將載具移動至另一份掃描文件的一端，以所決定的方 向來進行掃描。因此，本實施例可大幅的縮短掃描所需的 時間，而在掃描文件很多時此項優點就會更加明顯。 因此，本發明的優點係提出一種掃描器之多次無方向 性掃描方法，可利用程式控制掃描方向，即可根據使用者 08446twf 1 .doc 10 548953It must be noted that if the first part of the image f and the second part of the image obtained in this embodiment are to achieve the purpose of completing scanning with the least amount of data, the first part of the image and the second part of the image are not overlapped with each other as Otherwise, there are no restrictions on the acquisition of the first part of the image and the second part of the image. When the first part of the image and the second part of the image are restricted from overlapping each other, for example, the image can be taken at every other point on the line, or the image can be obtained at every other line, but this is not limited. That is, the image of the singular or even point on the line can be obtained when the vehicle is moving forward to form a first part of the image, and the image of the singular or odd point on the line can be obtained relative to the image of the line when the vehicle is moving backward to form the second part of the image. Alternatively, when the vehicle is moving forward, the singular or odd line is obtained as the first part of the image, and when the vehicle is moving backward, the double or singular line is obtained as the second part of the image. Of course, the restrictions on the acquisition of the first part of the image and the second part of the image cannot be separated only by the above. As long as the image can be obtained by the method described above, no matter how many points or lines are spaced, it can be used in the present invention. The advantage of this embodiment is that when the scanned document is to be scanned in full color, scanning will take a lot of time in the conventional processing. The invention can save a lot of time. For example, when the scanner is scanning at full-color 600dpi resolution, when the vehicle is moving forward, you can select the singular point for scanning at 300dpi, and when the vehicle is moving in the opposite direction, you can select the double-point for scanning. Scanning at 300dpi resolution, so combining these two graphics can achieve full-color 600dpi resolution, and can save more than half the time of conventional direct scanning full-color 600dpi resolution. Please refer to FIG. 6, which shows 75 according to another preferred embodiment of the present invention. 08446twfl .doc 9 548953 Appearance is slightly different;-& This embodiment is suitable for scanning in batches, that is, when there are multiple partial files to be scanned in batches. In this embodiment, a scanned image of a partial document is first obtained (step S600). Thereafter, it is determined whether to continue scanning in step S610. When there is no need to continue scanning ', it ends; if there are any part of the documents waiting to be scanned, the program determines whether to perform forward or reverse scanning according to the current situation (step S620). After deciding to process the next part of the document in forward or reverse scanning, the program will drive the vehicle to the place where the next part of the document is located, and perform step S600 to obtain the scan of this part of the document in the determined scanning method. image. In the conventional technology, when multiple scan files are placed in the scanner window at the same time to perform batch scanning, the vehicle must be returned to position after each scan file is processed, and the scan must be recalibrated before continuing the scan. . For example, when two scanning documents are placed on the transparent glass at the same time, according to the practice of a conventional scanner, after the calibration is completed, the carrier is driven to the first scanning document and starts scanning to obtain an image. After that, the vehicle must be homed, and then the vehicle is driven to the second scan file to start scanning. After obtaining the image, the vehicle is homed. Thus, it is very inconvenient for the vehicle to move back and forth twice for calibration. In this embodiment, after the first scanned document is scanned to obtain an image, the carrier is directly moved to one end of another scanned document and scanned in a determined direction. Therefore, this embodiment can greatly reduce the time required for scanning, and this advantage becomes more apparent when scanning a large number of files. Therefore, the advantage of the present invention is to propose a multi-directional non-directional scanning method for a scanner, which can control the scanning direction by a program, which can be based on the user 08446twf 1 .doc 10 548953
