Description of the invention (1 ^ Background of the invention 圊)-The scope of the invention related to telecommunications Η Vieie communications. In particular, the present invention is related to enhancing the usability of 4, ά4, Han Fuxing and other video transmissions, using di di on the screen, such as personal digital assistants or handheld computers or limited display 7F and / or limited reliance Monitor the capacity of other devices. Explanation of Early Technology_ The images and texts transmitted by the transmission machine are the most popular and new applications for voice and data communication devices, such as telephones. It ’s transmitted 3V image pass through the phone ’and received for image printing or storage on the destination transmission machine or computer for receiving purpose. Because the destination machine is typically already a transponder, computer, list machine, or other such large grain storage and output device, there is no need to significantly compress the transmission for the destination output device. Furthermore, it is no longer necessary for the transmission to be suitable for small handheld window scaling, as the traditional destination is already an original-size print, a computer monitor, or a large number of storage media. Due to the ongoing development of devices such as personal digital assistants (pDA) with small drawing windows, they are required to properly receive transmissions for the display and processing scheme of transmission images. It must be suitable to overcome the limitations of such devices. Although equipped with such drawing windows, these PDAs, unlike their counterparts in computers, have very limited memory and video capabilities. For example, on a p DA, the typical storage space is only 1 million bytes (1 MB) in total, and this space will be only 6 pages totaling 900 -4.

Description of the invention (2) ~ Transmission data of kilobytes (900 KB) is quickly filled. Such devices as PDA or handheld computer have the ability to receive transmission information, even if they are mainly used To send out these transmissions. But with this device, the receiver must scroll through all parts of the document image of the transmission 'or partially receive the transmission, and due to storage limitations, it cannot- Receive many pages or multiple transmissions. Thus, before they are finally viewed by the recipient on the destination PDA and display, there is an urgent need for compressed transmissions to be transmitted. Furthermore, because the screen size is in general The display and the transmission are small by comparison, once it is Receiving, there is a need to efficiently adjust the image to avoid-the recipient must scroll the entire image. Many technologies are well known and have been developed to adjust and compress these images, but these technologies are usually Computers are not computationally intensive compared to PDAs without a large memory system or microprocessor capabilities. Furthermore, these compression and adjustment architectures are never suitable for pass-by-pass, so it is appropriately displayed in On a very small display screen like a PDA display screen. Of course, many old technologies rely on one pixel to one pixel to adjust and shrink the entire image into a bitmap, and for a large amount of text that is accompanied by some image data The transmission files are not optimized. Therefore, in order to efficiently receive and display their special purpose on the PDA display screen or other twilight with limited micro processing capacity, a system and method are needed for compression and Adjusting these transmission images. Abstract The present invention is a method and system for use in a limited storage / processing National Standards (CNS) A4 (2I0X297 mm) (Please read the precautions on the back before f this page). Installation. • Thread A7 ------ B7 V. Description of the invention (3) Capability purpose A copy of a local device, such as a personal digital assistant (pDA) or a handheld computer, to view a copy (hereafter referred to as " transmission (fa X 广). When the child transmission is sent to the device, the call is Transfer to a computer or other device with a larger amount of storage and processing capacity compared to the destination device. The transfer is processed in the computer system by 'dividing the transfer' into these identifiable elements of the text , And then output these text elements to a transferable file. Along with these text elements themselves, information such as position or color shift is provided, so the text may be transformed more accurately at the destination device. Similarly, these drawing elements are transformed according to their coordinates and meanings, and are identified and stored. Drawing elements such as 芎 are also edge-fitted, so the curves and polygons are more efficiently represented. The drawing information is also output to the transferable file. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs, the complete transferable file, which can be further compressed, will include all the information necessary to reconstruct the transmission at the destination device. The transferable file is received by the destination device, and the device then uses the information in the 'file' to reconstruct the transmitted image on the window. The present invention is advantageous in that the number of transferable files is smaller than that of the original transmission itself, and can be adjusted more easily and quickly at a device with limited memory ^ / processing capacity such as a pDA and Review.

Description of the invention (4) Component. FIG. 4 is a block diagram showing the transmission image display elements on the personal digital assistant device. Fig. 5 is a diagrammatic representation of these stages of the process implemented on the present invention. · Detailed description of the invention When the present invention has been described with particular reference to these various diagrams, it should be understood that the diagrams are for illustration only and should not be used to limit the scope of the invention. With regard to the present invention, many changes and modifications may be implemented by those with ordinary skills in this technology, without-far from the spirit and scope of the present invention. FIG. 1 shows a schematic stitching diagram of the transmission path fe before the transmission data reaches the destination PDA device 40. FIG. An original transmission machine 10 (or other transmission-capable device) broadcasts a phone number of the destination PDA device 40 to transmit the information to it for viewing by a recipient. A router 20 'may be a ceiuar switch / psTN (Public Switched Telephone Network) or other communication router such as the ether, intercepting and re-routing the incoming router. Call to a computer system 30, which may be a single machine or a network of machines that can be remotely located away from the PDA device 40 for processing. Although described herein as just being implemented in a PDA device, the present invention may also be implemented in a handheld electronic device. The computer system 30 can then store the entire transmission in the computer system, or, as the packets of the transmission being received, process the transmission and store a paper, the standard is applicable to China National Standard (CNS) A4 specifications ( 2 丨 0X297 mm) (please read the notes of the back * before you go to this page). Binding and ordering printed by the Central Bureau of Standards of the Ministry of Economic Affairs and printed by the Shellfish Consumer Cooperative A7 B7 V. Description of the invention (5) Processed Biography. If the transmission is received and stored, then the communication port of the computer system is released for other operations, perhaps to receive another incoming transmission. The re-routing of the transmission to the computer system 30 also avoids binding the PD command device 40, so if the recipient so chooses, it can receive all transmissions at once. The transmissions may be collected and stored by the computer system 30 for later download. So the computer can operate as the same server to store the transmissions, and the user can choose whether to receive the transmission (s) immediately or waiting. Anyway, the transmission is processed for display on a window 45 of the PD device 40. However, instead, 'if the user chooses this way, it is not processed on the p D a device 40' and the transmission can be sent to a solid transmission machine for output. The computer system 30 outputs a processed version of the transmission into a transmission file (refer to FIG. 2), which includes all the components (graphics) that make up the transmission (the program is detailed later). And this article). The computer system 30 then compresses the transmittable data file 'so it can be transmitted more efficiently than normal data. The computer system transmits the compressed transmission-capable data file to the PDA device 40 through a communication port (described in detail later). The PDA device 40 decompresses the file and transforms the transmission image for display on its window 45. Disposal and processing of these components and software from source to destination are detailed in Figure 2. The transmission device 10 has a transmission unit 15 'which broadcasts a telephone number representing the destination PDA device 40. This phone number is worn by the router 20.

Description of the invention ( 8) After extracting the elements of this article) the remaining images into the polygons and lines. Edge fitting is well known in the art of drawing compression and transformation and will not be described in detail. Edge fitting generally consists of converting these curves into a series of straight lines. Advantageously, and unlike the edge fitting of earlier technologies, the edge fitting structure 350 is optimized to provide a smaller amount of linear approximation, so the interpolation method is not as good as a standard transition to the original size screen. Need to be right. This type of edge fitting is illustrated in Figure 5, where the images remaining after OCR are reduced to be represented by the transformable coordinates. For example, Fig. 5 shows this curve as two edges connected to a series of contours. The size of this window 45 is more φ, the resolution of the edge fitting is larger, and there are fewer contours to be calculated. Such detailed images are difficult to transform on a small low-resolution screen, for example, will be found on a small device such as a pda. So 'used to display on a standard-size screen of a computer screen, for example,' No need for the number of edges (lines) is the same as the edge fit, or the calculated incremental distance and edge of each line The fit comparison is just as small. The edge fitting structure 350 operates under a less stringent linear approach than the edge fitting structure of standard computer-aided augmentation and graphing software. For example, the target output of the present invention also has a lower resolution. In addition, the edge-fitting soil 35J3 can match the polygon network utility 'that reduces a tight shape into a series of connected lines, which approximates the curve of the tight shape. In this way, with a leading identifier type (the coordinates that are followed are considered to represent polygons instead of independent lines) and a series of uninterrupted coordinates, the entire polygon is reserved for later use at the destination Everywhere.

Furthermore, the polygon network information 'except for the identifier type and these coordinates, there are _ " field full (fill) flags, When its final transition at the destination rope window, the tight polygon is filled. This " full " flag avoids storing multiple lines, which is necessary under pure edge fitting to represent the shadow A more detailed description of such tight shapes 3 edge fitting and polygonization may be found in James D.

The final data file thus constitutes all the elements of the drawing and text in the original, transmission, and is used at the destination to adjust and transform the transmission for display on p DA window 45. When all the information is completed, the transferable data file 500 is then compressed by a compression technology such as pkzip (a product of pKWare). As such, the transferable data file 500 is reduced to a very small size, often 10 to 100 times smaller than the original transmission size. The typical page size of these transmission ranges is between 1 () and 2 and the final transmittable data case so compressed is less than 1K (roughly one page of ASCI1 text and digital data) The large, 1.

Unlike the computer system 30, the 'PDA device 40 may have only limited capabilities to transform the coordinates, draw lines, draft text, and adjust the images on the window 45. These capabilities of the PDA device 40 are discussed in more detail below. The data receiving unit 'element 410 provides the compressed file to a decompression structure 420 »The data file is then decompressed by a structure 420, such as using Pkunzip (if Pkzip is used during the compression phase of the computer system), decompressing' so The text elements, the position information used for the text, and the coordinates used for the lines and polygons can be useful for a transmission image adjustment and transformation unit 430. The transmission image adjustment and transformation unit 430 uses their ASCII codes, line by line, or word by word, to temporarily place these text elements into the Ministry of Economic Affairs Central Bureau of Prototype Bureau staff and cooperative printing (please read first Note on the back ^ Γ page) body 'and then by reducing (by calculating the size of the window coordinates of the text provided) the font size of the text, reducing the lines or groups of text. By adjusting the text information on a line-by-line basis, the relative positions of the text lines are preserved to give the transformed image the same look and feel as the original. Optimally, to complete the adjustment, a ratio equal to the quotient of the page size divided by the size of the child window 45 is calculated. Of course, if it is desired that a pass can be scrolled, the ratio can be calculated using the positive size of the window 45. This reduced font size can be implemented, it can handle any reduction ratio through adjustable fonts (like TrueType fonts), or by those fonts limited to a predetermined size. Using such fonts that are limited to a predetermined size, the ratio will be used to divide the original font size, and then the closest font size that can be used will be used. • 15 · This paper size applies Chinese national standards (CNS) Λ4 specification (210X 297 mm) A7 ------- B7__ 5.

The coordinates of are the coordinates suitable for the window 45. The text is then output at the coordinates provided on the transom (representing a window). In this way, all text elements are output to the window 45. Attack the transmittable data file 500. When ^ is decompressed, it will also contain line and rim information, which is provided to the transmission adjustment and conversion unit 43. The aging and conversion early element 43 0 is used, For example, the β ratio used for font reduction is calculated, and the coordinates provided from the transferable data file 500 are converted (graphed) to fit the window 45. In doing so, the unit 430 has also automatically trimmed the lines and polygons to fit the window, because the transmission coordinates are marked edge-to-edge over the window to cover the window. Then, the unit 430 transforms the lines and polygons to be drawn on the window 45. Printed by the Central Consumers Bureau of the Ministry of Economic Affairs, Consumer Cooperatives 31 The coordinate conversion of these polygons and lines and the font reduction of these text elements all require simple arithmetic, and in this way (compared to this computer system 30), it can be easily This limited processor power of PD A device 40 is performed. So the one-pixel-one-bit image is compressed, transformed, and adjusted (to fit the small window). The complicated procedure is skipped, and the result is an easily adjustable and fast Seen screen image. Adjusting a one-bit image requires linear edge fitting of all pixels in the field and cannot be performed by such devices as PD A. Although the present invention also uses a linear edge fitting type, it does so on a larger computer with the necessary processor, memory, and storage capacity to perform edge fitting. Furthermore, because the paper size of this publication ^ _- 16 -___ ^ applies the Chinese national standard (CNS > Λ4 specification (210 乂 297 mm 1 '' y cut the image into a string of predetermined lines and objects, the PDA device 40 can easily display and adjust these objects and lines, and reorganize the image. In addition, it may be beneficial to have a zoom (z〇〇ming) on the PDA device 40, so the receiving user can zoom in as An area of the image being displayed on the window, i or. This zoom feature is implemented by continuing only the coordinates of the lines and polygons that are desired to be zoomed to the entire window 45. Once again This operation is simple arithmetic, and is not as computationally intensive as adjusting normal & meta-images, it must decide which pixels are to be retained and that k is to be entered. The included within the coordinates of the zoom area After the elements of this article are trimmed, the size of other fonts is enlarged / reduced to a size that is proportional to the coordinate drawing ratio of the contours and polygons used in the source text. Cartography is a 3 of the computer system A simple block diagram of the components and structure 'that handles the transmission and transmits it to the Pda device 40. Also refer to the transmission entered by the child and run through an OCR 340. The result is two files-a bubble' minus The transferable data file contains the ASCII text and location information, and another 'the filtered file contains drawing images of the remaining Fs that are not recognized by the 0CR 340. The filtered file is then sent to the edge fitting Structure 350 'its edges cut the images into the polygons and lines. The coordinates (and other related information) of the lines and polygons are stored in the transferable data building case.> The transferable data file. It is completed one mile, and then compressed by a compression structure 3 70. The compressed transmittable data file is then transmitted to the pda device 40 by the data transmission unit 330 of the computer system 30 for display.

The data transferable file is received and then decompressed into its original form by the decompression block 420. The transferable file's The text information, such as this text and related location information, is provided to the transmission adjustment block 432. The transmission adjustment block 432 is marked with a 'roughly representative' ratio of the original scanned image size to the window coordinates It is proportional to the coordinates provided. The adjustment block 432 also reduces the font size of the text elements representing this ratio. In parallel or pipeline manner, the text, the lines and polygons are then borrowed The transition block 434 is displayed on the window 45 at the same time or at the moment when the adjustment is completed. A commonly used adjustment-deduction is found in Computer, Brain, and Yuan a (Computer Graphics ^ pages 202-204). Figure 5 illustrates these example images transmitted at various stages of processing. > A line, a circle, a curve and a pentagon are displayed with various elements 'this text'. In this text, [t] his is representative text " is filtered by the OCR software. The software also provides this The coordinates of a window, such as (12,12)-(29,14), are placed in this document. The transmissible data file receives these coordinates, accompanied by an " 1 " identifier, which indicates the following 5 Mysterious coordinates: a rectangular wood-window where the text is to be placed. The wood-text is then copied into the transmissible building case after these coordinates. Of course, those familiar with the technology will know that the illustration is For illustration only, the same as this article is represented by a _ 8 5 (: 11 yards. After 0CR, the remaining file will contain the images that are not recognized by OCR. The line is converted into These coordinates (1 1, 1 7)-(1 9, 1 9) and also The first type identifier of " 2 " indicates that it is a line. The curve is converted into two straight lines, and the Chinese National Standard (CNS) A4 size (210X297 mm) is applied to this paper size. ) ----; ------ Installation— (Please read the notes on the back first and then this page) Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs Printing A7 ————- ϋ ______- V. Description of the Invention (16) The data transferable file is represented as two lines. The circle is identified by the edge-fitting software based on the coordinates of a radius line with an anterior burst status identifier of one, four, and one. Shown. The display of the transferable data file is not shown in Figure 5. The polygon is similarly divided into a series of phases. Linked coordinates rather than contours, because they are connected in nature. Unlike those that are connected by A leading identifier type used for such circles, lines, or text is also provided before the streain. Also not shown is an option to fill the flag, which may match the circle and Polygons are provided to indicate that it should be filled in solids when transformed. Cooked Those who know this technology will already understand that the _ number representing color can also be transmitted along with other text and drawing information, so that the color change at the window can be realized just like black and white. "Although the present invention has been explained as PDA operation, compared to a computer system, this method is quite suitable for any window on a device that requires limited processor and memory capacity, such as a PDA. As an alternative embodiment, it occurs on a PDA device 40 This adjustment can be implemented in the computer system 30. The computer system 30 may have a query file identifying the model of the PD device and the size of its window to which the transmission will be sent. This query file may contain, in case the computer system 30 is used to handle these different transmissions to different recipients at different times, and the phone number of the destination device is used as a key. In accordance with this index, the computer system 30 can determine the parameters of the pDA device and the window, whereby it can convert the coordinates to a type and size used by the PDA device 40. In this way, the p D A device does not even need to perform the arithmetic adjustment, and may be -19- (please read the precautions on the back of this page first) -installation.
