Abstract

In a method of electronic recording of information from an information carrier, a position-coding pattern (3) is placed on top of or under the information carrier. The information on the information carrier and the position-coding pattern (3) are imaged with the aid of a plurality of partial images. The position-coding pattern is used to determine where the partial images should be stored in a memory area. The partial images in the memory area together constitute an image of the information on the information carrier. The position-coding pattern is filtered out of the partial images. A product, a device, and software used for implementing the method are also described.

(2) US 5,852, 4 34 describes the arrangement for recording handwritten text by determining the absolute position on the writing surface. The configuration includes a writing surface provided with a position code, a pen-shaped device with a pen tip and a detector capable of detecting the position codes, and a computer capable of determining the position of the device relative to the writing surface based on the detected position code. position. As the user writes on the writing surface, the f-stand code is continuously recorded along the path of the pen tip with the help of a detector. The recorded position code is transmitted to a computer for analysis. Finally, the results are output to a display or printer. However, this arrangement is not suitable for recording existing text or images. US 5,852,434 describes three examples of position coding. According to an example, the position coding is composed of points, and each point is composed of three concentric circles. The outermost circle represents the X-coordinate and the middle circle represents the Y-coordinate. • In other words, * the two outer circles are divided into 16 parts, which indicate incomplete numbers depending on whether they are filled. This means that each pair of X, Y coordinates is coded with a point with a specific appearance. The object of the present invention is to completely or partially alleviate the shortcomings of the conventional art device for electronic recording of text and images. This object is achieved by The method of recording information as described in item 1 of the scope of patent application, the product intended to be used in the electronic record of related information as described in item 12 of the patent application scope, as described in item 23 of the patent application scope The computer-readable media, the device described in the 27th scope of the patent application, and the system described in the 29th scope of the patent application are achieved. More specifically, according to a first aspect of the present invention, it is Regarding the electronic recording method of information from an information carrier, the method includes the steps of placing a thin plate with a position-coding model and the information carrier so that they are relative to each other. -------- Equipment ------ 1T ------ Thousands (Please read the precautions on the back before filling out this page) 492242 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 1 -__V. Invention (3) stacked; promoter by several portions of the image information on the image carrier and the position of the coding model information; and using the position-coding model for image synthesis section is set for the imaging of the image information synthesized. According to the invention, a position coding model is thus applied to the position coding model by placing the position coding model on top or below the information carrier. Therefore, the information carrier was not initially provided with a position coding model. Instead, the model was applied temporarily or permanently later. This means that any image or text can be recorded with the help of a position coding model. Because the position coding model is used to collect part of the image, no special or separate position sensor is required. In addition, because the individual positions of the partial image are determined by the position coding model, the order or relationship of the partial images is not important. . For example, the recording of part of the image can be overlaid and the recording can start anywhere on the information carrier. The important thing is that some images together contain all the information that will be recorded, because this makes it possible to combine some images into a composite image. In addition * some images can be combined into a composite image efficiently with the help of a position coding model. Implementation • It requires less processing power than using the inclusion of partially overlapping partial images to aggregate them • In addition * The accuracy and predictability of the combination of some images does not essentially depend on the information of the information carrier The position coding model can be projected as a light model on the information carrier, copied on the information carrier in a duplicator or placed on top or below the information carrier in any other suitable manner. However, in a preferred embodiment, the step of placing includes placing the paper size applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) (I read the precautions on the front side and write next to it). V. Description of the Invention (4) A7 B7 The sheet of the location coding model printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is printed on the top or bottom of the information carrier. The position coding model is placed in such a way that the position coding model and the information carrier are placed on top of each other in a moment in the simplest and cheapest way. In a preferred embodiment, the sheet with the position-coding model is transparent except for the position-coding model and is placed on top of the information carrier. This makes it possible for the information carrier's information and position coding model to be simultaneously imaged in each partial image. The position coding model can then be used to unambiguously determine a position for the imaged information part in each part of the image so that the parts of the image can be grouped together without any distortion. However, only a part of the image is recorded every second time for the information on the information carrier and only a part of the image is recorded every second time for the position coding model. In this embodiment, the information and the position coding model can be imaged by electromagnetic radiation with different wavelengths and can have different wavelength characteristics. • If a sheet with a position coding model is placed on top of the information carrier, the sheet and the position coding The model must be transparent to the electromagnetic radiation in this embodiment * the information is imaged * and the position-coding model is imaged to be opaque to the electromagnetic radiation • Since the device for recording information in this embodiment must be Can send electromagnetic radiation of different wavelengths * which will be more complicated and therefore more expensive • In addition, because the recorded position coding model and information are imaged by different parts of the image, the part of the image used to determine the position and the There is a displacement between the next (or previous) part of the information of the other part of the image and the position of the part of the information. In a preferred embodiment, the method according to the invention includes a further step of filtering out the position encoding model. .

Description of the invention (5) The synthetic image will basically constitute the image of the information on the information carrier without the need for a position coding model. This filtering can be implemented within the composite image or preferably within a partial image. When the location coding model is superimposed on the information of the information carrier, it will hide some information. In order to recreate the original information as much as possible, the filtering of the position encoding model is preferably effective by replacing the pixel value representing the position encoding model with the pixel value obtained by representing the average pixel value representing the information. This averaging operation is preferably performed near the pixels to be replaced. In this context, averaging also includes weighted averaging by pixel values. The position coding model may consist of symbols. In this case, the filtering preferably includes for each symbol the steps of calculating the average of the pixel values adjacent to the periphery of the symbol and replacing the pixel value representing the symbol with the average of the pixel values. As mentioned above, the position coding model makes it possible for the image collection to become a composite image of the information. • This image collection preferably includes a decision based on the position coding model of the image in the same or adjacent parts for the part of the information. A position and the sub-steps of deciding where the information should be stored according to the determined position • Since the position obtained by the position coding model represents the position of the same or adjacent part of the image on the information, it may be in the position The information is re-created on the information carrier. · In most cases, some of these images will overlap to some degree. This can be used to improve the image: if the part of the image to be stored in the memory area When a pixel overlaps with a pixel previously stored in the memory area, the average pixel value of these overlapping pixels is preferably calculated, and the precautions of 'reading the r surface first' are written first.

Invention (6) The pixel values are stored is replaced with the average. In a preferred embodiment, the method includes the steps of: if the first part of the position-coding model on the sheet is detected, the information on the information carrier is imaged with a first resolution; if the second part of the position-coding model is The information on the 'detected' information carrier is imaged at a second resolution. In this way, the user can select the speed at which the information on the information carrier is recorded to some extent, so that when a lower resolution is sufficient, a faster record can be made. The different parts of the position coding model may be, for example, parts with different circular appearances or parts coded by coordinates with different coordinate intervals or regions. All steps of the above method are advantageously carried out "automatically" with the exception of placing the position-coding model on top or below the information carrier by a device for recording images and having a processor for processing the images as described above with software. According to a second aspect of the present invention, there is an electronic record about a product designed to be used for information about a hip carried by a piece of information. The position of the product containing at least one sheet is provided with a position-coding model that crosses The sheet extends and encodes several positions on the sheet. The part of the sheet is transparent except for the position coding model. The sheet-shaped part is suitable for being placed on the top of the information carrier for recording information by it. The product For example, it can contain a thin plate-shaped part or a plastic folder, the position coding model is provided in front of it, and an information carrier in the form of a thin plate or a piece of paper with text and images can be placed therein * The product is understood from the above discussion of this method · In a preferred embodiment of the present invention, each bit of the position coding model is 9-This paper size is applicable to China National Standard (CNS) A4 specification (21 × 297 mm) -------- -矣 ------ 1T ------ Mu (Xu first read the notes on the back and then fill out this page) 492242 A7 printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs ^ _V. Invention Description (7) Placed by Set a particular portion of the coding model, and this is also part of the position-coding model for encoding the position of the adjacent Cause. In the conventional art, each position is encoded with its own code or symbol, which is "isolated" by the codes or symbols of the surrounding positions. The resolution of the position is therefore limited by the portion of the surface occupied by the symbol or code of the position. However, according to the present invention, a specific part of the position encoding model is used to encode several positions. In this way, a "floating" transition between positions is obtained, making it possible to improve the resolution of the position. In addition, on the other hand, it may reduce the relationship between the size of a portion that must be read to facilitate position determination and the size of a specific portion of a position coding model that encodes a position on the other hand. The position coding model may be any configuration such as a line, a circle, or a surface, which contributes to the unambiguous coding of the position. However, as mentioned above, the position coding model preferably consists of a number of models having at least a first type. Symbol composition. In most basic embodiments, it has only the first type of symbol, and the position is encoded with the help of the distance between these symbols. • Or * the encoding can be binary, the existence of the symbol represents 1, and the symbol There is no representative 0. However, this type of encoding can cause problems when the position is encoded with only or initially 0. In most preferred embodiments, the position encoding model consists of only the first and second This type of model or appearance consists of several symbols. • This model can be used for binary coding. • Since these symbols are very simple * for example, they contain two points of different colors or diameters, they are easy to apply. * Because of the information of each symbol The content is small, so the surface with this model is easy to manufacture. In addition, it is helpful for image processing. Moreover, the symbols are preferably uniform on the surface. 10- This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) (please read the precautions on the back to write this page first) mi; -线-五 # Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 __B7_ Description of the invention (8) The uniform distribution makes it particularly easy to create and interpret the model. In order to facilitate the model to be created from only a few different types of symbols and still allow encoding of a large number of locations, each of the several locations is preferably encoded with the help of several symbols. In this case, it is advantageous that the symbol coding of the positions is distributed in two dimensions, in such a way that the same position resolution can be achieved in the two vertical directions of the surface. Each symbol is preferably the cause of the encoding of one or more of these positions. However, it may have edge effects that prevent this from being satisfied in situations where the sign is rare. The position coding model is optically readable, so that both the position coding model and the information can be recorded with the same sensor. The model must therefore be able to reflect, emit or absorb light. However, this light need not be in the visible range. The model can also be fluorescent, which can be activated by electromagnetic radiation from the device used to record information from the information carrier. The symbols in the model can be of any suitable type. It is preferably graphical, making It does not need to implement character recognition (OCR) in the determination of the position, but it may also contain several characters. In addition, the shape of these symbols is preferably regular. These symbols can be identified fundamentally independently of the image rotation within a portion of the image. It may be, for example, a square, a polygon, a line, or preferably a circle. In addition, the symbols are suitably composed of two colors having a contrasting effect of black, white, or red and green. A symbol is filled with the first color in the inner circle and the second color in the outer circle.

Invention Description (9) The color filling to the edge of the inner circle is particularly preferred. In this way, the symbol can be identified with the help of a circular boundary line between the first and second colors. This identification is reliable because it is not distorted by the information on the information carrier on which the position coding model is superimposed. The above model of the symbol does not necessarily have to be placed on a transparent sheet. When part of the image is recorded as an alternative with a position-coding model or information on an information carrier, it can also be used perfectly on opaque sheets. The position encoding model can be made randomly, so it does not contain any information about the position it encodes, but a part of the position encoding model, which is located on a part of the surface, and must conform to the position encoding model of the entire surface. To facilitate the location of the surface of that part. However, this has the disadvantage that this position determination requires a large amount of processor capacity * In addition, it is difficult to randomly generate a position encoding model without ambiguity unless we are willing to accept a considerable amount of redundancy. Or, each A number of positions can be defined by the first and second coordinates * which can be determined using the part of the position coding model located on the surface of the relevant part * The position coding model represents the address where the positions of the first and second coordinates are stored • However * The position coding model composed in this way requires a lot of memory hip space. Therefore, in a preferred embodiment, the position coding model is constructed in such a way that a position coding model that encodes certain positions essentially contains information about Information about this position · More specifically, the position coding model is preferably based on the first string of symbols, which contains a first predetermined number of symbols and has characteristics that are better than -12- _Matters written on this page).

Description of the Invention (10) The second predetermined number of symbols, which are preferably consecutive, are obtained from the first string of symbols. The position is determined unambiguously, and the first string of symbols is used to determine the position of the first dimension of the partial image on the information carrier. Since the position encoding is based on a series of symbols, a limited number of symbols are arranged in a predetermined order. It may define a "formula". Use & to determine the position in the first dimension on the surface String symbols require only a small amount of memory space, and location decisions can be implemented quickly and easily. The position in the first dimension can be represented by, for example, a Cartier coordinate or a polar coordinate system.

Description of Invention (12) Figure 1 shows a part of a transparent sheet 1 with a surface 2. The position-coding model can be read optically on 3 is administered. The sheet 1 may be part of a product, such as a plastic clip, but in this case the sheet constitutes the entire product. The position coding model 3 is composed of the first and second types of symbols 4a, 4b, more specifically points with different appearances, and the point 4a has a black center point surrounded by a ^ colored ring, which represents 1; and Point 4b has a white center point surrounded by a black ring, which represents 0. These points have been magnified for clarity. Its size and distance are equal. The position coding model is configured so that if a device images a point on a part of a surface of a predetermined size, a part of the surface of the thin plate can be automatically determined by the image processing aid in the device. The second image processing part surfaces 5a and 5b. The position coding model part located on the first part surface 5a constitutes a first specific part 6a as one of the position coding models. This first specific part encodes a first position 7a, which coincides with the middle symbol on the part surface. Correspondingly, a second position 7b is encoded by a specific part 6b of the position encoding model located on the second part surface 5b The coding model is thus shared by adjacent positions 7a and 7b. The first example of a position coding model that facilitates position determination will now be described. This model is suitable for position determination using imaging with image processing containing 5X5 symbols. As mentioned above, these symbols represent binary coding. The sheet has X and γ directions. To encode the position in the X direction, a 32-bit sequence of 1s and 0s is generated in the first step. In a second step, a 31-bit sequence of 1s and 0s is generated by removing the last bit of the 32-bit sequence. This binary sequence will be referred to as the X-number 15-this paper scale applies to China Standard (CNS) A4 specification (210X297 mm) --------- 矣 ------ 1T ------ ^ (Please read the precautions on the back before filling this page) 492242 A7 ___B7_ V. Description of the invention (13) The word sequence should have the following characteristics: if five consecutive numbers are selected anywhere in the sequence, a unique group of five bits is obtained, which will not exist Anywhere else in those series. If someone "connects" the tail of the series to the head of the series, it should also have this characteristic. The five-bit group thus provides an unambiguous encoding of the positions of the series. An example of a 32-bit sequence with the above characteristics is: "00001000110010100111010110111110". If the last 0 is removed from this sequence, a 31-bit sequence with the same characteristics is obtained from the first five bits in the above sequence, that is, 0000 1, which constitutes the encoding of position 0 in the sequence, and the next five bits, GOGIO constitutes the encoding of position 1, and so on. The position in the X number can be expressed as a function of these five-bit groups, which are stored in Table 1. Naturally position 31 exists only in this 32-bit sequence. The following table 1 shows the position code of the above example.

The written five-bit group can be used to encode 31X32 = 992 positions in the direction of the column. For example, suppose the following encoding is written on the sheet: 000 " .11111000001000110010100111010110111110 ". 000 ··· 1111100001000110010100111010110Π11100. &Quot; If these five-bit groups are translated into positions according to Table 1, the following positions of the 32-bit and 31-bit sequence are indicated on the sheet. 0 1 2 ... 30 31 0 1 2 ... 29 30 31 0 1 2 0 1 2 ... 30 0 1 2 3 ... 30 0 1 2 3 4 The encoding in the X direction is therefore based on the use of a sequence containing n bits.It is composed in such a way that it has m consecutive results. The numbers of are obtained from these series. These m numbers will unambiguously encode the positions in the series. The number of codeable positions is increased by using a second series, which is a partial set of the first series. Therefore, it is different from the length of the first sequence. The permutations are obtained in the longitudinal direction of the columns. The encoding in the Y direction is based on the same principle. A sequence is created (hereinafter referred to as the Y number sequence), which contains P numbers. If r consecutive numbers are obtained from this sequence, these r numbers encode the positions in the sequence, so the position of the direction is not ambiguous. • In Y -18- (read the precautions on the back first, write this page) 9¾ Binding and binding The paper size is applicable to Chinese National Standard (CNS) A4 (210X29 * 7mm) 492242 β Printed by A7 B7, Employee Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (16) Numbers in the number series The model on the thin plate is coded to calculate the difference between the two columns of X-direction positions in a special method. More specifically, the alternating sequence of 31-bit and 32-bit sequences is written as follows: Column 1: (31) (31) (3 1) (3 1) · · Column 2: (32) (32 ) (32) (32) ·· Column 3: (31) (31) (31) (31) · ► Column 4: (32) (32) (32) (32). Column 5: (3 1 ) (3 1) (3 1) (3 1) · · Naturally, these series are written on the sheet using two dots of different sizes. These columns start at different positions in the X number sequence. To be more specific, one starts two consecutive examples in the following way: if one determines the difference of the modulus 32 between the two upper and lower position numbers, the difference is represented by a five-digit binary number, and the five-digit number is taken The largest two significant digits of a binary number. This number will be the same regardless of which one is in the column. In other words, the way someone starts the sequence is to permutate between the two consecutive columns. The entire column is maintained at a specific interval. In this example, the largest permutation is 31 positions or bits. The permutations along each pair of columns are at 0-7, 8-15, 16-23, or 24-.

Take 26-18 of columns 3 and 4 as an example, which is equal to 8, which is 0100 in binary code. The maximum two significant digits are 01. If instead, someone takes 0-h in the same column, its 32 modulus is equal to 9, and the largest two significant digits are 01, which is exactly the same as the previous example.

Now, if the same way as the X direction, someone creates a Y number sequence from the numbers 0, 1, 2, and 3, and its characteristic is that if four consecutive numbers are obtained from the sequence, the position in the sequence will be unambiguously It was decided that it might find 0013 in the table to unambiguously position the position in the Y direction. In this way, it is possible to determine 2 56 unique positions in the Y direction. The following are examples of the beginning and end of a Y number sequence containing the numbers 0-3.

Invention Explanation (I9 11 (01011 10 (01010) read first, memorize the meaning of the above b) Page 05 (00101) Therefore, the magnitude of the substitution between the positions in different columns is determined by taking the difference modulus 32 The two largest significant digits of the difference determined in this way are represented as five-digit two-digit numbers, that is, G, 1, 0, 0. According to Table 2, this difference number is equal to position 3 in the Y direction. Therefore , The coordinate of the second dimension on the sheet is 3. The third table of the alignment stores the starting position of each column, that is, the position in the X number sequence of each start. In this case, with the help of the y coordinate 3, we find The starting position of the recorded five-bit group being taken out is possible. • Knowing that the starting position of the top two five-bit groups being taken out is the X corresponding to the two five-bit groups. Position (ie, positions 26 and 26) determines the X coordinate or The position of the first dimension is possible. For example, suppose that the starting positions of the top two columns are 21 and 20 respectively. In this case, the two columns of the top two five-bit groups are taken out of the recorded image. It looks like this: Column 3: 21 22 23 ... 29 30 31 0 1 2.-25 26 27.

The fact that it matches is that the odd-numbered columns are composed of 32-bit The composition of the sequence and the even sequence consist of a 31-bit sequence. That is, the sequence 3 consists of a 32-bit sequence and the sequence 4 consists of a 31-bit sequence. Based on this information, the X coordinate may be determined to be 35. This can be recorded. 22 This paper size applies the Chinese National Standard (CNS) A4 specification (210 × 297 mm).

A Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 Invention Description (20) The remaining pairs of the five-digit group of images were verified by repeating the above steps. The cause has some amount of tolerance. The accuracy of position determination can be further improved by determining the position of the middle point of the 5X5 group relative to the image center. This position resolution is therefore better than the distance between the two symbols. Naturally, the above steps are implemented in software, which in this example gives coordinates 3 and 35 as their output signals. The position coding model can also be used to determine the position in the third dimension (ie, the Z direction) with respect to the surface. This is achieved by determining the size of the symbols in the recorded image and comparing them with reference values that are represented when the information recording device is imaged using the information recording device. The information recording device is fixed to the surface where the position-coding model is placed. In this way, the device can therefore automatically determine whether the device is close to the surface, so the image should be recorded or separated from the surface. The image should not be recorded, and the image recording should be triggered accordingly. The above description is about an example and can be generalized accordingly. It is not necessary to have 32 numbers in the first number sequence. This sequence depends on how many different symbols there are. Depending on the position in the X direction, the number of recorded symbols is used. For example, if the number of different symbols is 3 and the number of recorded symbols is 3, the number of numbers in the X number sequence will be 3X3X3 = 27, not 32. The same reasoning applies to Y numeric sequences. The bases of these sequences can therefore be different. The number of position-coded symbols and the number of positions subsequently coded by the sequence can also change. May not be based on the symbol of a number, and can therefore be described as a symbol string. -23- This paper size applies to China National Standard (CNS) A4 (210X297 mm) ) --------- ^ ------ # ------ Finally (please read the notes on the back before filling this page). A7 B7 V. Description of Invention (21) Just like As mentioned above, these symbols can be of many different kinds. It can also be digital, but in the case where OCR software is required to implement location determination, this can make the device for image recording more complex and expensive. This also leads to increased error sensitivity. The benefit of the above method of encoding position on the surface and implementing position determination on the surface is that it requires only a very small amount of memory and processor capacity. In the above example, only 32 columns are needed to store Table 1, 256 cases are in Table 2, and 256 columns are in Table 3. The location decision can be implemented using a look-up table of three tables and simple calculations. Furthermore, the method of encoding the position on the surface is also beneficial, because any rotation of the image on which the position is determined can be captured relative to the surface on which the position is to be determined. In the first place • An image contains a series that should be horizontal. This means that there are only four possible alignments. In 98% of cases, only one of the four rows will give a position. • In case of doubt, it can record two adjacent images and based on all possible rows of the symbols in these images. It is removed to determine these positions. The criterion is that the position determination should form the result of two adjacent positions. According to the coding mentioned above, the position determination can also be implemented in a way other than the above. Part of the surface of the position coding model The recorded image can be matched with the image of the entire position-coding model. However * this requires a lot of processor capacity. Alternatively, the symbols in the image can be translated into addresses in the table where the coordinates are stored. However, this requires a large amount of memory capacity. A second example of the position coding model is described below. It is in conformity with the above-mentioned mold-24-1 paper size applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). Packing-(Read first_ _ notes on the back to write this page). Cooperatives printed A7 B7, invention description (22) type has essentially the same properties. This storage location coding model includes a virtual scanning surface, which is invisible to the human eye, and will not be directly detected by the device that will determine the location on the surface, and several symbols, each of which can be described as follows Take one of four values "1" to "4". Figures 2a-d show an embodiment of a symbol that can be used in the position coding model according to the invention. The symbol includes a virtual scanning surface point 106 represented by the scanning surface line intersection point, and a mark 107 having the form of a point. The value of the symbol depends on where the label is located. In the example of Figure 2, there are four possible positions, one on each scan line extending from the scan point. The permutation from the scanning surface points is equal to all values. In the following, the symbol in 2a has a value of 1, 2 in FIG. 2b, 3 in FIG. 2c, and 4 in the 2d circle. In other words, there are four different types of symbols. Each symbol can thus represent four values "Bu 4". This means that the position coding model can be divided into the first position code of the X coordinate and the second position code of the y coordinate * This division takes effect as follows: Symbol value X code Y code 1 1 1 2 0 1 3 1 0 4 0 0 Therefore, in this case, the value of each symbol is translated into a first number (bit) of the X code, and is translated into a second number (bit) in the y code. In this way, two completely independent bit models are obtained. • These models can be grouped together. 25 — This paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm).

Description of the invention (23) A common model is synthesized, which uses several symbols in Figure 2 to be drawn. Formally each position is encoded using several symbols. In this example, a position is coded using two-dimensional ', i.e., 4X4 symbols of the X and y coordinates. The position code is composed of a sequence of 1 and 0, and its characteristic is that a sequence of 4 bits will not appear more than once in the sequence. This sequence is cyclic. This means that when someone connects the end of the sequence to the beginning of the sequence, the feature is still valid. Therefore, a four-bit sequence never violates a non-ambiguously determined position in the sequence. The sequence can have up to 16 bits if it has the characteristics of the above 4-bit sequence. However, in this example, you can only use a sequence consisting of 7 bits: "0001010". The seven unique sequences of the 4 bits that encode the position of the sequence are as follows: The sequence of positions in the sequence 0 0001 1 0010 2 0101 3 1010 4 0100 5 1000 6 0000 In order to encode the X coordinate, the sequence is written sequentially in the Line across the entire surface to be coded. This code is based on the difference between the numbers of adjacent lines. -26- This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back first) β write this page)-Binding. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 1-out 2242 A7 B7 A printed description of the invention (24) or the replacement of the location by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. The magnitude of the difference is determined by where in the sequence someone started the row (that is, in which sequence). More specifically, if someone gets a 4-bit sequence on the first line and therefore has a value (position) of 0-6 is encoded and on the other hand the corresponding number in the adjacent line (ie the same "level" Sequence), the result will be the same regardless of where someone compares in the second line. Using the difference between the two rows, it is thus possible to encode the X coordinate as a constant for all y coordinates. Since each position on the surface is encoded in this example with a 4x4 symbol, the three differences (having the value G-6) as described above can be used to encode the X coordinate. The encoding is then implemented as: one of the three differences is often 1 or 2 and the other two will have values in the range 3-6. Therefore, no difference in the X code is allowed to be 0. In other words, the X code is constructed so that these will be as follows: (3-6) (3-6) (1 -2) (3-6) (3-6) (Bu 2) (3-6) (3- 6) (Bu 2) ... Each X coordinate is thus coded as a two between 3 and 6 and a subsequent number of 1 or 2. • If you subtract 3 from the high number and subtract 1 from the low number * the number of mixed bases will be obtained * which is directly obtained The position of the X direction, the X coordinate can be directly determined as shown in the example shown below. Using the principle described above, it is possible to encode the X coordinates 0, 1, 2, ... with the help of three numbers representing the difference. These differences are encoded according to the bit model based on the above sequence. • This bit model is finally encoded in the form of the symbol map in Figure 2. • In many cases, it is impossible to generate a complete encoding of the X coordinate when reading 4x4 symbols. The number is only a part of the two numbers. Since the least significant part of such numbers is always 1 or 2, the complete number can be easily reconstructed. 27- This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling out this page)-Binding · Binding-Line 492242 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 __B7_ V. Description of the invention (25) The Y coordinate is coded according to the same principle as the X coordinate. The cyclic sequence is repeatedly written in a row across the surface to be coded. But just like in the case of the X coordinate, these columns allow different positions in the sequence (ie different sequences) to start. However, as far as the y-coordinate is concerned, someone does not use the difference, but instead encodes the position-number with a number based on the starting position of the sequence on each column. When the X coordinate of the 4X4 symbol has been determined, it may in fact be determined by the sequence of the columns of the y code included in the 4X4 symbol. In the y-code, the maximum significant digit is determined by making this only for those having a value in a specific range. In this example, someone ordered the rank of 4 to start at position 0-1 of the sequence to indicate that this rank has the least significant digit in the y coordinate and the other 3 begin at positions 2-6. Therefore, it has the following sequence in the y direction: (2-6) (2-6) (2-6) (0-1) (2-6) (2-6) (2-6) (0-1) (2 -6) .... Therefore each y-coordinate is encoded with three numbers between 2 and 6 and a subsequent number between 0 and 1. If 1 is subtracted from the low number and 2 is subtracted from the high number, it is possible for someone to obtain the position of the mixed base in the same way as the X direction in the y direction, and thus it is possible to directly determine the y position. Using the above method, It is possible to encode 4X4X2 = 32 positions in the X direction. • This position corresponds to three differences, which results in 3X32 = 96 positions. In addition, it may encode 5X5X5X2 = 250 positions in the y direction. • Each of these positions corresponds to 4 columns, which results in 4 X 250 = 1000 positions. • All of them are calculated together, which may encode 96,000 positions. • Because the X-coding system is based on Poor, it may choose to decide where the series starts at * If someone considers that this first series can start at seven different positions, it may be -28- $ Paper size applies Chinese National Standard (CNS) A4 specifications ( 210X297 mm) 1 '(Please read the precautions on the back to write this page)-Binding and threading 2242 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V.

The starting positions of the seven different first series mentioned above can be coded on the writing surface of different papers or products. Seeing a further explanation of the position coding model of this embodiment, hereafter is a special example which determines the described embodiment according to the position.

The four-digit position on a mixed basis is 0X50 + 4X10 + 1X2 + 0x1 = 42. The third column in the Y code is therefore the 43rd, which has a starting position of 0 or 1, and since there are four columns in each of these columns, the third column is the number 43X4 = 172 · Therefore, in this example, the position of the upper-left corner of the 4X4 symbol group is (58, 170) * Since the X sequence of the 4X4 group starts at column 170, the X rows of the entire model start at the sequence ((2 0 4 6) — 1 69) Take the position of the modulus of 7 = 1 6 3 5 • Between the last start position (5) and the first start position, the numbers 0-19 are coded on the mixed basis, and by adding the mixed basis The number 0-19 represents, we can get the total difference between these lines. • A rule of innocence to do so is to generate these 20 numbers and directly add up the numbers. • One of the 30 obtained — this paper scale applies to China Standard (CNS) A4 specification (210X297 mm) Xiang Scale Manuscript Ϊ-Binding · Binding-Line 492242 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ___B7_ V.

Of course this is just an example. Locations can be encoded with more or fewer symbols. The number of symbols does not have to be the same in both directions. The lengths of these series can be different and must be binary, but can be other bases. Different sequences can be used for X-direction encoding and y-direction encoding. The symbols can be different series values. In the example above, they are marked as dots, but of course they can have different perspectives. For example, it may contain a dotted line that starts at a virtual scan line point and thus extends to a predetermined position. Preferably, it may contain the points described above, with the inner ring filled with a first color and the outer ring filled with a second contrast color to the edge of the inner ring.

The information on the information carrier is drawn as a dotted sun and cloud. Some images of 3G-33 are recorded in such a way that they overlap with left-to-right motion. Subsequently, the user lifts the device and gently places it on the right side of the partial image 33, after which the partial image 34-3 9 is recorded before and after use. The user continues to pass through the information carrier through the device until the entire area he wishes to record has been scanned. During scanning, the device records images at a predetermined frequency, and the LED 13 generates a strobe pulse of the same frequency (such as 100 Hz). When the sensor has recorded a part of the image, it is read by the image processing 16 and is processed immediately after being buffered in the memory.

This position can be represented as a pair of coordinates. The rotation of this part of the image relative to the information carrier can be determined according to the configuration of the symbols in the position coding model. In addition, the position i of some images can be more precisely determined by determining the position of the position-coding model on the sensor. In the next step (step 44), the position coding model is filtered out from this part of the image. This takes effect by the processor determining, for each formed point of the position coding model, the pixel value closest to the surrounding point. The processor then restores the image by replacing, for each symbol (ie point), all pixels in a portion of the image that constitutes the point with the average pixel value of pixels adjacent to the point's periphery.

Description of the Invention (33) When all the partial images have been stored, the memory will contain the composite digital image of the area on the information carrier that has been scanned with the device. This digital image can be incorporated into a fax, document or e-mail message or the like. This image can also be used as an input signal to OCR or ICR software. This software system is used to interpret the text in the image and store it in a character-encoded format. In addition, part of the stored image can be displayed on the display 20 to help the user see the area on the information carrier that he does not cover. For this purpose, one pixel on the display 20 corresponds to a certain area on the transparent sheet, and is turned on immediately after the corresponding area has been covered. Another alternative is that the information recorded by the information carrier can be displayed on the screen of the fixed computer. These partial images are sent here so that the user can see how the synthetic image of the information on the information carrier is generated. In the example, the information is recorded simultaneously with the position-coding model with the help of electromagnetic radiation from more than one LED. Another alternative is that the model and the information can be recorded in an alternative manner such that one second image contains the model and one second image contains the information. In this case, the information and the model must Electromagnetic radiation is recorded at different wavelengths. The benefit of this embodiment is that the position coding model can be placed under the information and therefore need not be transparent.
