The processor 110 is a calculation unit, and by executing an application program, the printing device 1 edits characters to be printed on the print medium M.

FIG. 3 is an example of a flowchart of the character editing process. FIG. 4 is an example of the label editing screen before setting the font. FIG. 5 is a diagram for explaining a method of acquiring a reference image. FIG. 6 is an example of a reference image display screen. FIG. 7 is an example of a font selection screen. FIG. 8 is an example of a label editing screen after selecting a font. Hereinafter, the character editing process shown in FIG. 3 performed by the electronic device 100 will be described with reference to FIGS. 3 to 8.

The character editing process shown in FIG. 3 is a process of editing characters by changing font settings. The character editing process shown in FIG. 3 is performed by, for example, pressing the font setting button B1 on the label editing screen shown in FIG. 4 while the electronic device 100 is executing an application for editing characters to be printed on the print medium M. It will be started. FIG. 4 shows an example in which the edit target character C1 (here, “ABC computer”) is input to the edit area ER in the label edit screen. The character to be edited is a character to be edited by changing the character format such as a font.

When the character editing process is started, the processor 110 first acquires the character information of the character C1 to be edited (step S1). The character information is the content of characters that does not depend on the setting of the character format, and is specified by, for example, a character code. In addition, the characters include the appearance of the characters in addition to the content of the characters (character information), and even if they have the same character information, they have different appearances (formats such as fonts). Characters are treated as different characters from each other.

Next, the processor 110 acquires the reference image M1 (step S2). Here, the reference image M1 is an image including characters (hereinafter, referred to as reference characters) in which a character format (here, a font) that the user wants to set for the character to be edited is set. The reference image M1 may be acquired from the Internet by, for example, operating the electronic device 100 by the user, and is an image acquired by the user taking an image of an object with the image pickup device 104 of the electronic device 100. You may.

Note that FIG. 5 shows an example in which the user photographs the poster (object) 200 with the image pickup device 104 of the electronic device 100 and acquires the reference image M1. Further, FIG. 6A shows an example in which the acquired reference image M1 is displayed on the display unit 101.

When the reference image M1 is acquired, the processor 110 acquires the character information of the reference character C11 from the reference image M1 (step S3). The character information of the reference character C11 (here, "XYZ automobile") is acquired by using a technique such as optical character recognition (OCR) for extracting the character information from the image.

When characters other than the reference character C11 are included in the reference image M1, the processor 110 first performs preprocessing for setting a region of interest on the reference image M1 according to an input from the user, and then performs preprocessing. , The character information of the reference character C11 may be acquired from the region of interest. Here, the region of interest is a selected region in the reference image M1 and is an region including the reference character C11. As a result, the character information of the reference character C11 can be acquired more reliably. FIG. 6B shows an example in which a region of interest ROI (region surrounded by a broken line) including the reference character C11 is set on the reference image M2.

When the character information of the reference character C11 is acquired, the processor 110 generates a plurality of comparison images (step S4). Specifically, the processor 110 generates a plurality of comparison images, each including a character corresponding to the reference character C11, based on the character information of the reference character C11 and the plurality of fonts stored in the storage 105. To do. FIG. 6C shows an example of a plurality of comparative images P1 to Pn. Here, the character corresponding to the reference character C11 included in each of the plurality of comparison images is a character having the same character information as the reference character C11, and is stored in the storage 105 in the reference character C11. Each of a plurality of different fonts is applied. That is, the plurality of comparison images are a plurality of images in which each of the plurality of fonts is applied to the reference character C11.

When a plurality of comparison images are generated, the processor 110 calculates the similarity between the image of the reference character C11 in the reference image M1 acquired in step S2 and each of the plurality of comparison images generated in step S4 (). Step S5). The degree of similarity is a quantitative expression of how similar the two images are. Various methods are known as methods for calculating the similarity between images. The calculation method used in step S5 is not limited to a specific method. For example, the similarity between images may be calculated based on the LPB (local binary pattern) generated from the images. Further, the similarity may be calculated by using a similarity calculation method called Average Hash. In addition, for example, the similarity may be calculated by calculating the difference squared sum (SSD), the difference absolute value sum (SAD), and the normalized cross-correlation (NNC). Here, when the reference image M1 is acquired by photographing the object with the image pickup apparatus 104, the object may be photographed from a position deviated from the front and the object may be distorted. .. In such a case, for example, it is preferable to perform the above processing after deforming the reference image M1 so that the object is closer to the image when the object is photographed from the front.

When the similarity is calculated, the processor 110 selects at least one font from the plurality of fonts stored in the storage 105 based on the similarity calculated in step S5 (step S6). Here, the processor 110 specifies, for example, a font set in the comparison image in which the similarity with the reference image M1 is equal to or higher than the threshold value in the plurality of comparison images, and specifies at least one of them. It may be selected as the font of. This makes it possible to prevent the existence of similar fonts from being overlooked. The threshold value may be arbitrarily changed by the user. The processor 110 identifies, for example, a predetermined number of fonts set in a high-order predetermined number of comparison images having a high degree of similarity to the image of the reference character C11 in the reference image M1 in a plurality of comparison images. May be set as at least one specific font. As a result, the number of similar fonts can be narrowed down to a desirable number according to the size of the display unit 101 or the like in advance. The predetermined number may be arbitrarily changed by the user.

After that, the processor 110 displays a list of images of candidate characters in which different fonts are set (step S7). Here, the processor 110 applies at least one specific font selected in step S6 to the edit target character C1 to obtain at least one candidate character corresponding to the edit target character C1. At least one candidate character has the same character information as the edit target character C1. After that, the processor 110 displays a list of the obtained images of at least one candidate character on the display unit 101. As a result, an image of at least one candidate character to which each of at least one font is applied is displayed on the display unit 101. Note that FIG. 7 shows an example in which images Q1 to Q4 of four candidate characters (images of candidate characters C2, candidate characters C3, candidate characters C4, and candidate characters C5) are displayed in a list on the display unit 101. Has been done.

Next, the processor 110 monitors the selection of the candidate character by the user (step S8). Then, when the processor 110 accepts the selection of the image of one candidate character from the image of at least one candidate character displayed on the display unit 101, the selected one candidate character (hereinafter referred to as the first candidate character) is described. ) Is applied to the character to be edited C1 (step S9). Here, the processor 110 edits the edit target character C1 to the first print target character by applying the font, and updates the display of the label edit screen. In FIG. 8, as a result of selecting the candidate character C2 on the font selection screen shown in FIG. 7, the edit target character C1 in the edit area ER of the label edit screen is edited into the print target character C2 and becomes the edit target character C1. An example in which the print target character C2 to which the font is applied is set as the print target character is shown.

Finally, the processor 110 determines whether or not to end the character editing process shown in FIG. 3 (step S10), and repeats the processes of steps S1 to S10 until it is determined that the character editing process is completed.

In the electronic device 100, by selecting an image including a character (reference character) in which a font that the user wants to set for the character to be edited is set, the character to be edited is set to the same or similar font as the font. The images of the (applied) candidate characters are displayed in a list. Therefore, the user can easily edit the character to be edited into a favorite font simply by selecting an arbitrary character from the image of the candidate characters displayed in the list. Therefore, according to the electronic device 100, it is possible to reduce the work load of the user required for character editing.

Although FIG. 3 illustrates the process of editing characters by changing the font settings, the electronic device 100 may edit the characters by changing not only the font settings but also the general character format settings.

FIG. 9 is a modified example of the flowchart of the character editing process. FIG. 10 is another example of the reference image display screen. FIG. 11 is another example of the font selection screen. Hereinafter, the character editing process shown in FIG. 9 performed by the electronic device 100 will be described with reference to FIGS. 9 to 11.

The character editing process shown in FIG. 9 is a process of editing characters by changing the settings of general character formats (including italics, underlines, bold characters, etc. in addition to fonts). The character editing process shown in FIG. 9 is started by, for example, pressing a setting button for setting a character format on the label editing screen while the electronic device 100 is executing an application for editing characters to be printed on the print medium M. Will be done.

When the character editing process is started, the processor 110 first acquires the character information of the character C1 to be edited (step S11). Next, the reference image M3 is acquired (step S12), and the character information of the reference character C12 is acquired from the reference image M3 (step S13). The processing of steps S11 to S13 is the same as the processing of steps S1 to S3 shown in FIG. FIG. 10 shows an example in which the reference image M3 acquired in step S12 is displayed on the display unit 101. The reference image M3 includes the underlined reference character C12.

Next, the processor 110 generates a plurality of comparison images (step S14). Specifically, the processor 110 produces a plurality of comparison images, each containing a character corresponding to the reference character C12, based on the character information of the reference character C12 and the plurality of character formats stored in the storage 105. Generate. The character formats applied to each of the characters corresponding to the reference character C12 included in the plurality of comparison images are different from each other, and each is stored in the storage 105.

When a plurality of comparison images are generated, the processor 110 calculates the similarity between the image of the reference character C12 in the reference image M3 acquired in step S12 and each of the plurality of comparison images generated in step S14 ( Step S15), select at least one particular character format based on similarity (step S16). The process of step S15 is the same as the process of step S5 shown in FIG. Further, the process of step S16 is the same as the process of step S6 shown in FIG. 3, except that a character format is selected instead of the font.

After that, the processor 110 displays a list of images of candidate characters to which different character formats are applied (step S17). Here, the processor 110 sets at least one specific character format selected in step S16 to the edit target character C1 to obtain at least one candidate character corresponding to the edit target character C1. After that, the processor 110 displays a list of the obtained images of at least one candidate character on the display unit 101. As a result, an image of at least one candidate character to which each of at least one character format is applied is displayed on the display unit 101. Note that FIG. 11 shows an example in which images Q5 to Q8 of four candidate characters (images of candidate characters C6, candidate characters C7, candidate characters C8, and candidate characters C9) are displayed in a list on the display unit 101. Has been done.

Next, the processor 110 monitors the selection of the candidate character by the user (step S18), and when the selection of the image of one candidate character is accepted, the character format applied to the selected one candidate character is changed. It is applied to the character to be edited C1 (step S19). As a result, the edit target character C1 is edited, and the display of the label edit screen is updated. After that, the processor 110 repeats the processes from step S11 to step S20 until it is determined that the character editing process is completed (step S20YES).

When the electronic device 100 performs the character editing process shown in FIG. 9, the user can easily edit the character to be edited into a favorite character format by simply selecting an arbitrary character from the listed candidate characters. it can. Therefore, according to the electronic device 100, it is possible to reduce the work load of the user required for character editing.
Although FIG. 9 illustrates a process of editing characters by changing the character format setting, the electronic device 100 may further set a margin in addition to the character format setting.

FIG. 12 is another modified example of the flowchart of the character editing process. FIG. 13 is a diagram for explaining a method of calculating the size ratio between the printed matter and the reference character. Hereinafter, the character editing process shown in FIG. 12 performed by the electronic device 100 will be described with reference to FIGS. 12 and 13.

In the character editing process shown in FIG. 12, when the print data is transmitted, a margin is set in addition to the character format. The character editing process shown in FIG. 12 is started by pressing the setting button for setting the character format on the label editing screen, similarly to the character editing process shown in FIG. The processing from step S21 to step S30 is the same as the processing from step S11 to step S20 shown in FIG. Hereinafter, in step S22, a case where the reference image M4 as shown in FIG. 13 is acquired will be described as an example. The reference image M4 is an image obtained by capturing a printed matter P which is a label on which the reference character C14 is printed.

When the processor 110 determines in step S30 that the editing is completed, it determines whether or not a print instruction has been input (step S31). Here, the processor 110 determines, for example, whether or not the print button B2 on the label editing screen is pressed.

If it is determined that the print instruction has not been input, the processor 110 ends the character editing process shown in FIG. On the other hand, if it is determined that the print instruction has been input, the processor 110 acquires the size information of the print medium M from the printing device 1 (step S32). Here, the processor 110 acquires information on the size of the print medium M from the printing device 1 by requesting information from the printing device 1 via, for example, the communication IF 106. The size information of the print medium M is, for example, the tape width when the print medium M is a tape member.

Next, the processor 110 calculates the ratio of the size L1 of the printed matter P appearing in the reference image M4 to the size L2 of the reference character C14 printed on the printed matter P based on the reference image M4 acquired in step S22 (step). S33). Both of the above sizes (size L1 and size L4) may be the sizes in the reference image M4.

After that, the processor 110 sets the size of the characters to be printed on the print medium M (step S34). Here, the processor 110 prints on the print medium M based on the size information of the print medium M acquired in step S32 and the ratio value calculated in step S33, that is, in step S29. Determine and set the size of the edited candidate character. Specifically, the processor 110 sets, for example, the product of the size of the print medium M and the ratio (L2 / L1) to the size of the candidate characters.

Finally, the processor 110 transmits the print data including the candidate character edited in step S29 and the font size set in step S34 to the printing device 1 (step S35), and ends the character editing process shown in FIG. As a result, the edited candidate character is printed on the print medium M with the same balance as the balance between the reference character C14 and the margin in the printed matter P.

When the electronic device 100 performs the character editing process shown in FIG. 12, the user can easily edit the character to be edited into a favorite character format by simply selecting an arbitrary character from the listed candidate characters. it can. Further, the user can easily set the margin setting to the same balance as the reference image. Therefore, according to the electronic device 100, it is possible to reduce the work load of the user required for character editing.

The above-described embodiment shows a specific example for facilitating the understanding of the invention, and the present invention is not limited to the above-mentioned embodiment. The program, character editing method, and electronic device can be modified and changed in various ways without departing from the description of the claims. For example, although FIG. 1 shows an example in which the electronic device 100 is a portable computer, it may be a stationary computer. Further, in FIGS. 3, 9, and 12, although an example of selecting a plurality of fonts or character formats is shown, one font or character format may be selected, and one selected character format may be edited. The character to be edited may be set by setting the character.
