[0112] Figure 7 The operations S310a to S330a shown are embodiments of Figure 4 The operation S300 shown in FIG. Figure 4 After the operation S200 is performed Figure 7 Operations S310a and S320a are shown. Figure 4 , Figure 7 and Figure 8a In the embodiment of the present disclosure, in the operation S210 of identifying an element, at least one processor 150 (see Figure 3 ) Identify the elements included in the obtained input document IDa.

[0113] In an embodiment of the present disclosure, at least one processor 150 may recognize characters EMa, which are elements included in the input document IDa, through optical character recognition (OCR). In an embodiment of the present disclosure, in operation S220 of classifying the type of the input document IDa, when the elements included in the input document IDa include characters EMa, the at least one processor 150 may classify the type of the input document IDa as a first type. In an embodiment of the present disclosure, when the elements included in the input document IDa include only characters EMa but not images, the at least one processor 150 may classify the type of the input document IDa as a first type. As an example of the present disclosure, each element included in the input document IDa may correspond to one character EMa. Reference Figure 7 and Figure 8b In an embodiment of the present disclosure, the operating method of the electronic device 100 may include operation S300a: acquiring a calibration document CDa by arranging the recognized characters EMa in a row according to the order recognized based on the first type. In an embodiment of the present disclosure, the operation S300a of acquiring the calibration document CDa may include operation S310a: recognizing the arrangement order OEMa of the recognized characters EMa based on the first type. The operation S300a of acquiring the calibration document CDa may include operation S320a: acquiring calibration characters CEMa by calibrating the recognized characters EMa.

[0114] The operation S300a of acquiring the calibration document CDa may include an operation S330a of acquiring the calibration document CDa by arranging the calibration characters CEMA in a row according to the recognized order OEMa. In an embodiment of the present disclosure, in the operation S310a of recognizing the arrangement order OEMa of the recognized characters EMa, at least one processor 150 may recognize the arrangement order OEMa of the recognized characters EMa based on that the input document IDa belongs to the first type including characters as elements.

[0115] At least one processor 150 may identify the arrangement order OEMa of the identified characters EMa based on the content of the identified characters EMa and the space between the multiple identified characters EMa. In an embodiment of the present disclosure, at least one processor 150 may analyze the content of the identified characters EMa, and identify the arrangement order OEMa of the identified characters EMa based on the analyzed content. At least one processor 150 may determine the positions (such as spacing, line breaks, etc.) between the multiple identified characters EMa based on the space between the multiple identified characters EMa, and identify the arrangement order OEMa of the identified characters EMa based on the determined positions.

[0116] Figure 8bIt is shown that the order OEMa of the recognized characters EMa is recognized from left to right in the horizontal direction and from top to bottom in the vertical direction. However, the present disclosure is not limited thereto, and the recognition order OEMa of the recognized characters EMa may vary depending on the content included in the input document IDa. Figure 7 , Figure 8b and Figure 8c In an embodiment of the present disclosure, in operation S320a of generating the calibration character CEMa by calibrating the recognized character EMa, the at least one processor 150 may generate the calibration character CEMa by calibrating the recognized character EMa. Figure 8c It is shown that the size of the calibration character CEMa is larger than the size of the corresponding recognized character EMa by enlarging the recognized character EMa, but the present disclosure is not limited thereto.

[0117] The at least one processor 150 may acquire the calibration character CEMa by canceling the amplification of the recognized character EMa or calibrating the recognized character EMa by color inversion (such as negative color). Figure 7 , Figure 8b and Figure 8c In an embodiment of the present disclosure, in operation S330a of acquiring the calibration document CDa, at least one processor 150 may acquire the calibration document CDa by arranging the calibration characters CEMA in a row according to the recognized order OEMa. In an embodiment of the present disclosure, the characters EMa are arranged in multiple rows and columns in the input document IDa_1. At least one processor 150 may acquire the calibration document CDa by recognizing the character listing order OEMa in the input document IDa and arranging the calibration characters CEMA in a row according to the recognized order OEMa.

[0118] refer to Figure 7 and Figure 8d In an embodiment of the present disclosure, in the operation of displaying the calibration document CDa on the display 110, the at least one processor 150 may display a portion of the acquired calibration document CDa on the display 110. In an embodiment of the present disclosure, when the calibration character CEMa included in the calibration document CDa is an enlargement of the recognized character EMa, the size of the character displayed on the display 110 may be larger than that of the target document TD (see Figure 5 ) The size of the characters included in the .

[0119] Therefore, when viewing the characters displayed on the display 110, the visibility of the user US can be improved compared to viewing the target document TD directly with the eyes. In addition, the calibration characters CEMA included in the calibration document CDa can be calibrated by negatively inverting the recognized characters EMa. In an embodiment of the present disclosure, Figure 8dIt is shown that the output image IM includes a first output image IM1 and a second output image IM2.

[0120] The first output image IM1 is an image corresponding to the calibration characters CEMa.

[0121] The second output image IM2 may be a background image of the first output image IM1. The electronic device 100 may perform color inversion by negative color inversion so that the grayscale of the first output image IM1 is higher than the grayscale of the second output image IM2.

[0122] When viewing the output image IM provided by the electronic device 100 , the visibility of the user US may be improved compared to viewing the target document TD directly with the eyes.

[0123] However, the present disclosure is not limited thereto. In an embodiment of the present disclosure, the calibration characters CEMa included in the calibration document CDa may be calibrated by canceling the magnification of the recognized text EMa.

[0124] In this case, the size of the characters displayed on the display 110 may be smaller than the size of the characters included in the target document TD. Therefore, when viewing the characters displayed on the display 110, the number of characters entering the field of view of the user US may be increased compared to viewing the target document TD directly with the eyes. In an embodiment of the present disclosure, the output image IM may include a portion of the calibration document CDa. In an embodiment of the present disclosure, when the time period during which the output image IM corresponding to the entire calibration document CDa is provided to the user US by the electronic device 100 is referred to as an image cycle, the electronic device 100 sequentially displays the output image IM including a portion of the calibration document CDa to the user US during a plurality of image frames included in the image cycle. In an embodiment of the present disclosure, the electronic device 100 displays the output image IM including the beginning portion of the calibration document CDa on the display 110 within one image frame. The electronic device 100 displays the output image IM including the next portion of the beginning portion of the calibration document CDa included in the output image IM of the previous image frame on the display 110 during the next image frame.

[0125] The electronic device 100 may repeat this process during the image period until the output image IM including the last portion of the calibration document CDa is displayed on the display 110. Figure 7 and Figure 8d, the electronic device 100 displays an output image IM including “The ban” (which is the beginning part of the calibration document CDa) on the display 110 in the first image frame. The electronic device 100 displays an output image IM including “yellow” (which is the next part of “The ban” in the calibration document CDa) on the display 110 in the second image frame (which is a frame after the first image frame). The electronic device 100 displays an output image IM including “mind.” (which is the next part of “yellow” in the calibration document CDa) on the display 110 in the third image frame (which is a frame after the second image frame).

[0126] However, the present disclosure is not limited thereto. The number and size of the calibration characters CEMa displayed on the display 110 may vary based on the degree of magnification of the recognized characters EMa.

[0127] As the degree of magnification of the recognized characters EMa increases, the number of calibration characters CEMa displayed on the display 110 decreases, and the size of the calibration characters CEMa may increase. Figure 1 ) can be improved. In an embodiment of the present disclosure, characters EMa are arranged in multiple lines in the target document TD and the input document IDa.

[0128] Therefore, when the user US directly views the target document TD or when the input document IDa is provided to the user US, the user US needs to move his / her sight line up or down to understand the content of the target document TD or the input document IDa. In an embodiment of the present disclosure, when the content included in the target document TD or the input document IDa continues from one line of characters EMa to the next line, the user US needs to move his / her sight line from the right end of the previous line to the lower left of the next line. Therefore, the user US needs to move his / her sight line downward and to the left.

[0129] In this case, when the user US's line of sight moves downward to a row other than the next row, it may be difficult for the user US to understand the meaning of the contents. In addition, this problem may also occur when an output image IM including characters obtained by enlarging characters EMa included in the target document TD or the input document IDa is provided to the user US in order to improve visibility for the user US. When the output image IM including enlarged characters is provided to the user US, the number of characters that can be included in the output image IM is reduced due to the larger size of the enlarged characters. Therefore, it may be difficult for the user US to determine whether the line of sight has been moved to the desired row when moving the line of sight upward or downward based on the contents of the peripheral characters, and thus it may be difficult for the user US to move the line of sight to the desired row.

[0130] In an embodiment of the present disclosure, the calibration characters CEMa included in the calibration document CDa are in the recognized order OEMa (see Figure 8b ) are arranged in a row. The order of the calibration characters CEMa sequentially displayed on the display 110 by the electronic device 100 is consistent with the order of the target document TD (see Figure 5 ) and the input document IDa (see Figure 8a ) in the same order as the characters EMa included in it.

[0131] In an embodiment of the present disclosure, the output image IM displayed by the electronic device 100 includes calibration characters CEMa arranged in a row. The user US viewing the output image IM provided by the electronic device 100 does not need to move his / her sight up or down to understand the meaning of the content. Therefore, when viewing the output image IM provided by the electronic device 100, the visibility of the user US can be improved.

[0132] refer to Figure 7 and Figure 8a In an embodiment of the present disclosure, the input document IDa may include a first text document IDa_1 and a second text document IDa_2, wherein the first text document IDa_1 includes content including a first text TG_1, and the second text document IDa_2 includes a second text TG_2 and a third text TG_3. In an embodiment of the present disclosure, the first text TG_1 includes a plurality of first characters EMa_1. The first text TG_1 is a text in which a plurality of first characters EMa_1 are arranged in sequence according to the content order of the content.

[0133] The second text TG_2 includes at least one second character EMa_2. The second text TG_2 is a text in which a plurality of second characters EMa_2 are arranged in sequence according to the content order of the content. The third text TG3 includes at least one third character EMa_3. The third text TG_3 is a text in which a plurality of third characters EMa_3 are arranged in sequence according to the content order of the content. In the following, for ease of description, the first text document IDa_1 is defined as an input document IDa of the first subtype, and the second text document IDa_2 is defined as an input document IDa of the second subtype.

[0134] In an embodiment of the present disclosure, in the operation S210 of identifying an element, at least one processor 150 identifies a plurality of characters EMa_1, EMa_2, and EMa_3 included in the acquired input document IDa of the first subtype or the acquired input document IDa of the second subtype. In an embodiment of the present disclosure, the operating method of the electronic device 100 may further include the following operations: based on the arrangement of the plurality of identified characters EMa_1, EMa_2, and EMa_3, the type of the input document IDa is classified into the first subtype or the second subtype. In an embodiment of the present disclosure, when the space between the plurality of identified characters EMa_1, EMa_2, and EMa_3 remains constant and is greater than a preset space, the at least one processor 150 may classify the input document IDa as the second subtype including the second text TG_2 and the third text TG_3 that are different from each other. When the space between the plurality of identified characters EMa_1, EMa_2, and EMa_3 is less than the preset space, the at least one processor 150 may classify the input document IDa as the first subtype including the first text TG_1. In this aspect, the preset space may be a space corresponding to a space between two adjacent characters. Figure 8a It is shown that the input document IDa_2 of the second subtype includes the second text TG_2 and the third text TG_3 divided in the horizontal direction, but the present disclosure is not limited thereto. The input document IDa_2 of the second subtype may include two texts divided in the vertical direction.

[0135] Furthermore, the input document IDa may include other subtypes containing three or more texts.

[0136] refer to Figure 7 and Figure 8b In an embodiment of the present disclosure, the operation S300a of acquiring the calibration document CDa may further include: recognizing an order of the plurality of recognized characters EMa_1, EMa_2, and EMa_3 based on one of the first subtype or the second subtype.

[0137] In an embodiment of the present invention, when the type of the input document IDa is classified as the first subtype, at least one processor 150 may identify the order OEMa_1 of the plurality of first characters EMa_1 based on the content or space of each of the plurality of first characters EMa_1 included in the first text TG_1. In an embodiment of the present disclosure, when the type of the input document IDa is classified as the second subtype, at least one processor 150 may identify the order ORGa of the second text TG_2 and the third text TG_3 based on the content of each of the plurality of second characters EMa_2 included in the second text TG_2 and the content of each of the plurality of third characters EMa_3 included in the third text TG_3. After identifying the order ORGa of the second text TG_2 and the third text TG_3, at least one processor 150 may identify the order OEMa_2 of the plurality of second characters EMa_2 based on the content or space of the plurality of second characters EMa_2 included in the second text TG_2. After recognizing the order ORGa of the second text TG_2 and the third text TG_3, the at least one processor 150 may recognize the order OEMa_3 of the plurality of third characters EMa_3 based on the content or space of the plurality of third characters EMa_3 included in the third text TG_3.

[0138] However, in an embodiment of the present disclosure, at least one processor 150 may also recognize the order ORGa of the second text TG_2 and the third text TG_3, the order OEMa_2 of the plurality of second characters EMa_2, and the order OEMa_3 of the plurality of third characters EMa_3 together. Figure 7 , Figure 8b and Figure 8c In an embodiment of the present disclosure, the operation S330a of acquiring the calibration document CDa may include acquiring the calibration document CDa by arranging a plurality of recognized characters EMa_1, EMa_2, and EMa_3 in a row according to an order OEMa recognized based on any one of the first subtype or the second subtype. In an embodiment of the present disclosure, when the input document IDa_1 is classified as the first subtype and an order OEMa_1 of a plurality of first characters EMa_1 is recognized based on the first subtype, at least one processor 150 may acquire the first sub-calibration document CDa_1 by arranging a plurality of first characters EMa_1 in a row according to the recognized order OEMa_1.

[0139] In an embodiment of the present disclosure, when the input document IDa_1 is classified as a second subtype, and the order ORGa of the second text TG_2 and the third text TG_3, the order OEMa_2 of multiple second characters EMa_2, and the order OEMa_3 of multiple third characters EMa_3 are identified based on the second subtype, at least one processor 150 can obtain a second sub-calibration document CDa_2 by arranging the multiple second characters EMa_2 and the multiple third characters EMa_3 in a row according to the identified order ORGa, OEMa_2, OEMa_3, respectively.

[0140] In an embodiment of the present disclosure, the order in which the plurality of second characters EMa_2 and the plurality of third characters EMa_3 included in the second sub-calibration document CDa_2 are arranged may correspond to the order ORGa of the second text TG_2 and the third text TG_3.

Figure 12b A sequential OSG in which the recognized scenes SF_1 and SF_2 are alternately arranged from the upper left to the lower right is shown, but the present disclosure is not limited thereto.

[0170] The order of the recognized scenes may be arranged alternately from the upper right to the lower left, or from the top to the bottom, or from the left to the right, and is not limited to any one. In an embodiment of the present disclosure, in operation S320c of recognizing the sixth character EMa_6 from the character scene SF_1, at least one processor 150 may perform OCR to recognize the sixth character EMa_6 included in the character scene SF_1, and recognize the order OSEM of the recognized sixth character EMa_6 based on the content or space of the recognized sixth character EMa_6. Reference Fig.11 and Fig.12cIn the embodiment of the present disclosure, the operation S300c of acquiring the calibration document CDc may further include an operation S330c of: obtaining the calibration document CDc in the order OSG (see Figure 12b ) Arrange the recognized scenes SF_1 and SF_2 in a row to obtain the calibration document CDc.

[0171] Fig.12c It is shown that the character scene SF_1 and the non-character scene SF_2 are arranged in a row according to the recognized order OSG, and the sixth character EMa_6 recognized from the character scene SF_1 is arranged together in a row at the lower end of the character scene SF_1 corresponding thereto. However, the present disclosure is not limited thereto, and the character scene SF_1 and the non-character scene SF_2 may also be arranged in a row according to the recognized order OSG to obtain the calibration document CDc. In addition, the sixth character EMa_6 may be arranged at the side or upper end of the character scene SF_1 corresponding thereto.

[0172] refer to Fig.11 and Fig.12d , the electronic device 100 displays an output image IM on the display 110 within the first image frame, the output image IM including a scene located at the beginning portion of the calibration document CDc. In an embodiment of the present disclosure, when the scene included in the first image frame is a character scene SF_1, the electronic device 100 displays an output image IM including the character scene SF_1 and a sixth character EMa_6 corresponding to the character scene SF_1.

[0173] The electronic device 100 displays the output image IM including the scene following the character scene SF_1 included in the output image IM displayed in the first image frame on the display 110 in the second image frame which is a frame following the first image frame in the calibration document CDc.

[0174] The electronic device 100 displays an output image IM including a scene after the scene included in the output image IM displayed in the second image frame in the calibration document CDc on the display 110 in the third image frame. In an embodiment of the present disclosure, when the scene included in the third image frame is a non-character scene SF_2, the electronic device 100 displays the output image IM including the non-character scene SF_2.

[0175] In the embodiment of the present disclosure, the electronic device 100 sends the OSG to the user US (see Figure 1 ) in turn provides the target document TD (see Figure 5 ) / Input document IDc( Fig.12a ). Therefore, the user US viewing the output image IM provided by the electronic device 100 does not need to search the order of the scenes SF in order to understand the meaning of the content. Therefore, the visibility and convenience of the user US viewing the output image IM provided by the electronic device 100 can be improved.

[0176] Furthermore, when an output image of an enlarged scene including a scene SF included in the target document TD or the input document IDa is simply provided to the user US in order to improve visibility of the user US, it is difficult for the user US to understand the content of the peripheral scene, and thus it is difficult to search for an order of scenes SF suitable for the meaning of the content. Unlike this, in the present disclosure, a calibration document in which the recognized scenes SF are enlarged and calibrated and arranged in a row in order is provided to the user US.

[0177] Therefore, the enlarged scene SF may be provided to the user US, and the user US does not need to search the order of the scene SF, so that visibility and convenience of the user US may be improved.
