方法若不是在後續處理的程序上顯得繁雜，就是影像資料 在從記憶體輸出到主機的速度上顯得緩慢。 有鑒於此，本發明提出一種光學掃描裝置之記憶體中 影像資料排列方法。使用本發明所提出的影像資料排列方 法，在後續影像的處理程序上可以比前述習知所使用的第 一種方法更爲簡易，而在影像資料輸出的速度上’則可以 比前述習知所使用的第二種方法更爲快速。 本發明提出一種光學掃描裝置之記憶體中影像資料 排列方法，其適用於以數個像素組成一條線，且每一個像 素是由數個原色所組成的影像資料上。此光學掃描裝置之 記憶體中影像資料排列方法首先取得掃描一條線時所得 之一種原色，之後，再將此線中所包括的像素分成數個群 組。而在儲存其中一個群組到記憶體的時候，就於儲存所 取得之原色的位址前後保持一個儲存空間，以使組成同一 個像素的數個原色可以以同樣的順序相鄰排列於@憶體 中。最後，每當一個群組所包含的像素的原色齊備時’就 將此群組所包含之資料送出。 4 本紙張尺度適用中國國家標準（CNS)A4規格（210 x 297公t ) (請先閱讀背面之注意事項再碑寫本頁) .¾ 訂： 535400 五、發明說明) 本發明另提出一種光學掃描裝®之記憶體中影像資 料排列方法。此記憶體中影像資料排列方法首先將掃描一 條線所得之數個像素分成數個群組以儲存於記憶體中。之

藍色原色的影像資料儲存到記憶體內之後，組成第一條線 所需的影像資料就已齊備’此時這些組成第一條線所需的 影像資料就會被傳送到主機中以進行下一步的影像處理 操作。 由於在本實施例中使用的是線性光感測器，亦即相對 於每一種原色只有一條感測列，所以奇像素與偶像素兩部 分的影像資料可說是幾乎同時取得。而若使用的是交錯式 (staggered)光感測器，則以〜般奇像素與偶像素分離掃描

Description of the invention (/) The present invention relates to a method for arranging the memory data of an optical scanning device, and more particularly to an optical scanning device Method of arranging image data in memory. / Picture 1 of Mengmeng Mengzhao Table ’It cannot draw the architecture diagram of a general optical scanning device. The optical scanning device includes a charge coupled device (CCD) 110, a multiplexer 120, an amplifier 130, an analog-to-digital converter 14G, and a buffer memory 150. During scanning, the brightness obtained by scanning the scanned object by the charge coupling element 110 is converted into an analog voltage signal, and the analog voltage signal is output to the amplifier 130 by the multiplexer 120 according to the color sequence. After the amplification operation by the amplifier 130, the amplified analog voltage signal is converted into a digital voltage signal by the analog-to-digital converter 140, and the digital voltage signal is stored in the buffer memory 150. As for the data output and conversion operations described above, when the line difference of each color sensing row in the charge-coupled device 110 is k and there are n pixels, the digital voltage signal is stored in the buffer memory 150. Will be arranged as shown in Figure 2. Among them, Rij represents the red brightness of the j-th pixel (pixel) in the i-th row, Gij represents the green brightness of the j-th pixel (pixel) in the i-th row, and Βυ represents the i-th row The blue brightness of the j-th pixel (pixel). In the conventional scanning procedure, when the digital voltage signal has been stored in the buffer memory 150, there are two possible operations. The first method is to directly output the data in the buffer memory 150 to the host; the second method is to process the data in the buffer memory 150. 3 This paper size applies the Chinese National Standard (CNS) A4 Regulations (210 X 297 mm) (Please read the notes on the back first, then this page) m. Order_-line · 535400 7880twf.doc / 009 A7 B7 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Explanation (>) The colors of the pixels are arranged together before output. In the first method, although the speed of outputting data from the buffer memory 15 is fast, the image data arranging procedure that must be performed in the host is more complicated. In the second method, although the subsequent arrangement of the image data required in the host computer is simpler than the first method, the speed of data output is far lower than the first method. In summary, the conventional method of arranging image data in memory is either complicated in the subsequent processing procedures or the image data is slow in outputting from the memory to the host. In view of this, the present invention provides a method for arranging image data in a memory of an optical scanning device. Using the image data arrangement method proposed by the present invention, the subsequent image processing procedure can be more simple than the first method used in the previous practice, and the speed of image data output can be higher than that in the previous practice. The second method used is faster. The invention provides a method for arranging image data in the memory of an optical scanning device, which is suitable for image data composed of a plurality of pixels, and each pixel is composed of a plurality of primary colors. The method for arranging image data in the memory of the optical scanning device first obtains a primary color obtained when scanning a line, and then divides the pixels included in the line into several groups. When storing one of the groups in the memory, a storage space is maintained before and after the address of the obtained primary color is stored, so that several primary colors that make up the same pixel can be arranged next to each other in the same order. @ 忆Body. Finally, whenever the primary colors of the pixels contained in a group are complete ’, the data contained in the group is sent out. 4 This paper size applies to China National Standard (CNS) A4 (210 x 297 g) (please read the precautions on the back before writing this page). ¾ Order: 535400 V. Description of the invention Another optical method is provided by the present invention. How to arrange the image data in the memory of Scanner®. In this memory image data arrangement method, a plurality of pixels obtained by scanning a line are first divided into several groups to be stored in the memory. After that, when the data of the pixels contained in a group is complete, and the primary colors contained in these pixels are arranged in a fixed sequence ', the data of the pixels contained in this group will be sent. The present invention also provides a method for arranging image data in the memory of an optical scanning device, which is suitable for image data composed of a plurality of pixels in a line 'and each pixel is composed of a plurality of primary colors. The method for arranging image data in the memory of the optical scanning device first obtains a primary color obtained when scanning a line, and then divides odd pixels among the pixels included in the line into a first group, and even pixels into a first group. Group. When storing the first group or the second group in the memory, maintain an appropriate storage space before and after storing the addresses of the obtained primary colors, so that the primary colors that make up the same pixel can be arranged next to each other in memory in a fixed order. Body. Finally, when the primary colors of the pixels contained in the first group or the second group are complete, the data contained in this group is sent. In summary, the present invention obtains the data (i.e., the brightness of each primary color) that composes the pixels, stores the data in the memory in a specific order, and outputs the data directly. In this way, since no additional processing is required when the data is output from the memory, the output speed will not slow down, and because the output data has been processed in order, it can also be compared in subsequent image processing programs. Easy and fast.
