" After the knife is completed, it can be served and the above-mentioned automatic cutting technology has different performance and higher performance, usually in the computer::: need: a larger one - In view of the above, the present invention provides a method for automatically cutting a scanned image boundary of a manuscript, comprising providing a manuscript presser for covering the manuscript; The manuscript press has Having at least one first ribbon zone and a second ribbon zone disposed in a scan line direction, the length of the first and second ribbon zones exceeding a length of the document in a direction parallel to the scan line, scanning The manuscript and the manuscript presser obtain at least a first scan line data and/or a second scan line data, wherein the first scan line data includes the manuscript and the image of the first ribbon zone, and the second The scan line data includes an image of the manuscript and the second ribbon region; and analyzing the first scan line data and/or the second scan line data to position the document in a direction parallel to the scan line The present invention further provides a scanner capable of automatically cutting a scanned image boundary of a manuscript, comprising a manuscript presser, a scanning module and a signal processing unit, wherein the manuscript presser is used for overwriting The manuscript; wherein the manuscript press has at least one first ribbon zone and a second ribbon zone disposed parallel to a scan line direction, the length of the first and second ribbon zones exceeding the manuscript parallel to the Scan line The scan module is configured to scan the manuscript and the manuscript presser to obtain at least a first scan line data and/or a second scan line data; wherein the first scan line data includes the manuscript and the first An image of the ribbon region, the second scan line tribute includes the image of the phase and the two color ribbon regions; and the signal processing unit is configured to the first scan line data and / 201004310 or the second The scan line data is analyzed to locate the left and right borders of the document in a direction parallel to the scan line. The above described objects, features, and advantages of the present invention will be more apparent from the description of the preferred embodiments. [Embodiment] FIG. 2A is a schematic diagram of a scanner capable of automatically cutting a scanned image boundary of a document according to an embodiment of the present invention, and FIG. 2B is a schematic view of the scanner at another viewing angle. For example, the paper-feeding scanner 200 includes a roller 202, a scanning module 204, a signal processing module 206, a paper sensor 208, and a scanning window 210. . In this embodiment, the wheel axis of the roller 202 is parallel to a horizontal direction X for overlying the document member 212 over the scanning window 210 and feeding the document 212 in a vertical direction Y. In the paper-feeding scanner 200, the roller 202 has at least one first ribbon zone 222 and a second ribbon zone 224 disposed on the rolling surface of the roller 202. Only two ribbons are present in the figure. District, however, those skilled in the art can configure a plurality of ribbon zones without limitation. In addition, the colors of the first ribbon region 222 and the second ribbon region 224 are mutually high contrast colors. The higher the contrast between the two colors, the finer the effect of performing the automatic cropping image boundary of the present invention. In the preferred embodiment, the first ribbon region 222 and the second ribbon region 224 are respectively a black strip region 222 and a white strip region 224. However, the color selection is not limited thereto. In addition, the scanning module 204 of the present invention scans the document 212 in the horizontal direction X to generate a plurality of scanning line data, which is 201004310 in the horizontal direction x, that is, the scanning line direction. In addition to the effect of reducing the volume of the scanner 200, the roller 202 according to the embodiment of the present invention can simultaneously scan and automatically cut the image boundary of the document while feeding the paper (described in detail below). . However, in another embodiment, the present invention can be a conventional flatbed scanner (not shown) that does not have a roller feeding paper. The manuscript presser which is a laminated paper is a pressure plate, which can be used according to the present invention. The spirit of the invention is provided with at least two ribbon zones, and the ribbon zones are respectively distributed in a strip shape parallel to the horizontal direction, as shown in Fig. 2C. It will be readily apparent to those skilled in the art that when the roller 202 of the paper-scanner 200 feeds and scans the document 212, the effect achieved is also equivalent to Figure 2C. Therefore, whether it is a sheet-fed scanner or a flatbed scanner, the scanned image boundary of the document can be automatically cut according to the method of the present invention. The detailed steps of the method are described later. 3A is a flow chart of a method of automatically cutting a document boundary of a document in accordance with an embodiment of the present invention. Referring to Figures 2A and 2B together, in step S302, the present invention provides a manuscript presser, i.e., the roller 202 or the flat plate, for overlying the manuscript over the scanning window 210. Wherein the manuscript press has the black strip region 222 and the white strip region 224 disposed parallel to the horizontal direction, it is noted that the length of the black and white strip region must be greater than the length of the document in the horizontal direction. As shown in Fig. 2C, the requirements of the next step S304 are satisfied. In step S304, the scanning module 204 scans the manuscript 212 and the portion of the black strip 222 and the white strip 224 that are beyond the manuscript in the manuscript press, and at least obtains a first scan line data 232 and/or obtains a second scan line data 234, wherein the first scan 9 201004310 line data 232 includes an image of the manuscript 212 and the black strip 222, the second scan line data 234 includes the manuscript 212 and the white strip 224 image. However, if a more precise boundary position is to be cropped, more scan line faucets can be used, and the present example is only described by the >-known line poor material 2 3 2, 2 3 4 . Finally, in step S306, the signal processing unit 206 analyzes the first scan line data 232 and/or the second scan line data 234 to locate the left boundary and a right border of the document in the direction. FIG. 3B is a flowchart of a method for positioning the left boundary and the right boundary in step S306 in more detail. In step S306, the signal processing unit 206 performs the first scan data 232 and/or the second scan data 234. Binary processing. In step S310, the luminance values and coordinate values of the first scan points on the first scan line data 232 are as shown in FIGS. 4A and 4B, wherein the first scan line data 232 includes a plurality of first scan points. Aligning from left to right along the direction of the scanning line, respectively having coordinate values ranging from small to large (marked in the horizontal coordinate of Figure 4A) and brightness values (indicated in the ordinate of Figure 4A); The second scan line data 234 includes a plurality of second scan points arranged in a sequence from left to right along the scan line direction, each having a coordinate value ranging from small to large (marked in the horizontal coordinate of FIG. 4B) And the brightness value (marked in the ordinate of Figure 4B). In addition, in FIGS. 4A and 4B, the actual left boundary and the actual right boundary of the manuscript 212 and the black band 222 and the white band 224 are denoted as R1 and Rr, respectively, and are between the actual left boundary R1 and the actual right boundary Rr. The scan data generated for scanning the manuscript 212, and the scan data of the black band 222 or the white band 224 is scanned beyond the actual left boundary R1 and the actual right border Rr, however, the actual left boundary R1 10 201004310 and κ The right boundary Rr is the final target of the invention, and is naturally not obtained at the time of performing this step S310. The black band 222 is only for convenience because of its color. , substantially = for the document 212 having the ability to absorb light waves, as indicated by A, G in Figure 4A, and conversely, the white band 224 has its f color substantially corresponding to the manuscript 212 The reflected light wave = ' is a high brightness value, as shown by Η, Ν in Figure 4, and the second: is - a photo with various colors, then the first or second scanning point is redundant and the value is not present. Rule changes, as in the 4th figure, W in J~L . π u = in step S312, the signal processing unit pre-sets wherein the first threshold value & is a brightness value, and the familiarity should set its value to be slightly higher than the light yield value of the black band 222. :=! The processing unit - also pre-set - the value of = the value of the bean / familiar to the skilled person should = is approximately below the brightness value of the white band 224. Similarly, ^ , the value Bc and the second threshold Wc can also be analyzed by the first position (the scanning module 204 has a - maximum sweep) and the fixed position is greater than the brightness value of the scan points on the maximum scan. The score is = upper and outer, and the other: = other data analysis method of f. This black band = Γ: when there is no manuscript on the ,, the zone 224 is scanned separately, and the scanned image is scanned. The redundancy value is analyzed to obtain the first critical value and the number 201004310

In step S314+, he knows the data analysis method. ^ ^ A processing unit 206 separately binarizes the scan points of the two brothers: otherwise, the ride-and-degree value is higher than the first-place condition, the η-boundary value Bc in the bright map of the younger brother's scan point is two The value is a high value. For example, in the fourth 圊 〇, 〇 and £ respectively convert the brightness value lower than the first-threshold value Bc and = 弟 ^ 4A in the figure, a, b, c, f; 5 Γ value For a low value, such as the nth, ., and G are converted to A, B, c, F, wc ', etc., a third point in the brightness value is higher than the second critical value For the same value, as shown in Fig. 4B, Ιί, Ι, Κ, Μ, :f are converted into Η', Γ, κ', Μ, and Ν, and the exemption values of the second sweeps are lower than The second threshold value Wc is:: value, as in FIG. 4B, JAL is converted into J, and L', respectively. After the horse low phase 2 is binarized, the two adjacent points are high and low, respectively, and each other is not. (4) is a mutation. In the step of grasping the towel:: Γ! Trace points (such as C, D,, E, the value of the coordinate = the second L value 疋 is a first left boundary m' will be all the mutation of the first sweep ^ C'D', In E' and F'), the coordinate value of the largest coordinate value (F,) is determined by the right-right boundary Bl<; similarly, the second sweep of all mutations is -1'" J', K', L' And the coordinate value of the smallest coordinate value (ie, Γ) in M'), and the second boundary of the left-hand boundary of the second brother, W, will be in the second sweeping point (such as K, L', and Μ') The coordinate value of the largest coordinate value (Μ,) is defined as the second right boundary Wr. In step S318, the first left boundary B1 and the second left 12 201004310 side are the most sinful left in the wi (in this embodiment, the second left boundary % = boundary; and the first right The boundary & and the two right boundary Wr; the right one is determined as the right boundary (in the present embodiment, the first right boundary Br is equivalent to the second right boundary Wr). In the present embodiment, Looking at Figure 4A, it is found that although the first right boundary and the second right skill are approximately equivalent to the actual right boundary & the second left boundary is approximately equivalent to the actual left boundary R!, but the first The left boundary B1 is much different from the actual right boundary r. Therefore, the more scanned data is captured, the closer the image boundary is naturally cut to the actual situation. 'Familiar with the skilled person can do this according to the present invention. According to the above steps, after the steps S302 to S306 and S310 to S318, the paper-fed scanner 2GG can automatically cut the left and right borders of the scanned image of the document, however, the complete automatic cutting Also includes defining the upper boundary ^ : 3⁄4 " therefore 'refer to Dijon, 2B The paper-feeding scanning of the present invention further includes a paper sensor 208. When the paper sensor 2 〇 8 _ end emits light, if a document passes over the surface, the reflected light is detected by the other end of the sensor ( Receiving, and then matching the reflection of the manuscript (4) and calculating the walking length of the motor, the upper boundary and the lower edge of the scanned document can be determined. In the embodiment, when the paper sensor 2〇8 senses the manuscript At the upper edge of 212, the coordinate of the upper edge of the document 212 in the vertical direction B is defined as the upper boundary, and when the paper sensor 2〇8 senses the lower edge of the document 212, the lower edge of the document 212 is The coordinate in the vertical direction B is defined as the boundary. Thus, the method for automatically scanning the image boundary of the manuscript and the method of the present invention is 13: 201004310 ί == ί. Since the present invention is not mono, low, It can be achieved by the previous technology. The invention does not need to be cut in real terms. In addition, due to the well-prepared manuscript, the calculation resources of the system occupied by the needle ^ cutting are very small. Automatic should be applied as - portable equipment.
