This camera 15 can be, for example, an external WEB camera or a camera built into the liquid crystal display that constitutes the display unit 12 .

[Sealing process]
Next, the sealing process (S100) executed by the control unit 10 of the terminal device 1 in which the electronic seal stamp software is installed will be described with reference to the flowchart shown in FIG. In this specification, "S" in S100, etc. ("S" in the flow chart) means step.

The stamping process (S100) is executed (started) by the control unit 10 when the electronic seal stamp software is activated. In this embodiment, when electronic seal stamp software is installed in the terminal device 1 in which document creation software, document viewing software, etc., is installed, the electronic seal stamp software is incorporated as an add-in into the existing document creation software, document viewing software, etc. It's like Therefore, as shown in FIG. 5A, for example, when a document to be browsed (electronic document) is displayed on the display unit 12 (display screen) by document browsing software, the user stamps the document. , specify (select) the corresponding seal column (for example, the “Draft” column) on the document and perform input (for example, click the “mark icon”) to instruct the activation of the electronic seal stamp software (start of seal processing) You can start the electronic seal stamp software. Various inputs such as selections and instructions on the display screen are performed by the operation input unit 13 .

As shown in FIG. 3, in the stamping process (S100), first, the camera 15 is activated and a photographed screen is displayed on the display unit 12 (S101). An example of the shooting screen (shooting screen 20) is shown in FIG. Note that the photographing screen 20 and the later-described confirmation screen 30 and editing screen (not shown) can all be superimposed on the document display (see FIG. 5A) by document creation software or document viewing software. be done.

As shown in FIG. 6A, the shooting screen 20 includes a shooting target display area 20a (shooting target display section) in which a shooting target (subject) is displayed through a lens section (not shown) of the camera 15, and a shooting execution area. and a shooting icon 20b (shooting instruction input unit) for inputting an instruction (also referred to as “shooting instruction”). The object (object) to be photographed by this system is the face (expression) of the user (person who seals) of the terminal device 1 .

In the imaging target display area 20a, a frame line 20c is displayed, which is set according to the peripheral shape (seal impression shape) of the imprint image that can be stamped by this system. In this embodiment, the shape (seal imprint shape) of the frame line 20c is circular (round). By displaying the frame line 20c, it is possible to make it easier to visualize the imprint image (imprint shape) to be stamped.

The shape (seal impression shape) of the frame line 20c is not limited to a circle (round shape), and may be a shape other than a circle such as a square. Further, the shape (seal impression shape) of the frame line 20c may be arbitrarily selected by the user from a plurality of predetermined shapes. The selection input in this case can be performed by providing, for example, a button (selection button) for selecting the frame shape on the photographing screen and clicking the button.

The user (sealing person) looks at his or her own face displayed in the imaging target display area 20a (inside the frame line 20c) through the lens (not shown) of the camera 15, and adjusts the face so that it fits well within the frame line 20c. Move and reposition. Also, at this time, make an expression that matches your feelings when stamping, such as a smile or a stern face. Then, when preparation for photographing is completed, the photographing icon 20b is clicked while maintaining the position and expression of the face. Accordingly, a photographing instruction is input.

In this embodiment, as shown in FIG. 6A, the entire shooting target display area 20a, that is, the shooting target is displayed so as to be visible over the inside and outside of the frame line 20c. Only the inside of the line 20c may be displayed. In addition, the visibility of the outside of the frame line 20c is lowered from that of the inside by, for example, blurring the outside of the frame line 20c or displaying it translucent, so that the inside of the frame line 20c is clearly displayed. good too.

Returning to FIG. 3, after S101, the control unit 10 determines whether or not a shooting instruction has been input (S103). Then, if no photographing instruction is input (NO in S103), the process waits until a photographing instruction is input. On the other hand, when a photographing instruction is input (YES in S103), photographing is performed by the camera 15 (S105). In this embodiment, the content displayed in the entire shooting target display area 20a is the shooting target. It should be noted that it may be configured such that at least the content displayed inside the frame line 20c in the shooting target display area 20a becomes the shooting target. The processing of the camera 15 and S105 corresponds to an example of the "photographing means" of the present invention.

The image captured in S105 (also referred to as “captured image”) is stored (saved) in a predetermined storage area (captured image storage area) of the storage unit 11 . A captured image (photograph data) is stored (saved) as an image (raster data) in a raster format such as JPEG.

Next, in S107, based on the image (photographed image) photographed in S105, imprinting is performed to generate a seal imprint image (also referred to as a "facial imprint image") including the face (expression) of the user (sealing person). Processing is performed (S107). That is, the photographed image is subjected to a stamping process to generate a face stamping image of the user (sealing person) (S107). The process of S107 corresponds to an example of the "generating means" of the present invention. The details of the imprint processing (S107) will be described later.

Next, in S109, the face stamp image generated in S107 is displayed on the display unit 12 (S109). Here, a confirmation screen is displayed on the display unit 12 for allowing the user (person who seals the seal) to confirm the generated face impression image, and the face impression image is displayed on the confirmation screen. An example of the confirmation screen (confirmation screen 30) is shown in FIG. 6(B).

As shown in the figure, the confirmation screen 30 includes a stamp image display area 30a (seal image display portion) in which the generated face stamp image KG is displayed, and an instruction to redo the photographing (also referred to as "re-imaging instruction"). ) for inputting a re-shooting icon 30b (re-shooting instruction input section), and an editing icon 30c ( and a stamping icon 30d (stamping instruction input unit) for inputting an instruction (also referred to as a "stamping instruction") to stamp the generated face impression image. .

The outer circumference (seal impression frame) of the face impression image KG displayed in the seal impression image display area 30a corresponds to the frame line 20c displayed in the photographing object display area 20a of the photographing screen 20 described above (Fig. 6A, ( B)). It should be noted that the frame image forming the seal imprint frame of the face imprint image KG may be displayed as the frame line 20c in the imaging target display area 20a. By doing so, it is possible to make it easier to imagine the seal impression image at the photographing stage.

The user (sealing person) confirms the face impression image KG displayed in the seal impression image display area 30a, and clicks the retake icon 30b to retake the image. As a result, a re-imaging instruction is input (YES in S110), and the process returns to S101. On the other hand, if no re-imaging instruction is input (NO in S110), the process proceeds to S111.

The user (sealer) confirms the face impression image KG displayed in the seal impression image display area 30a, and clicks the edit icon 30c when correcting the face impression image KG. As a result, an edit instruction is input (YES in S111). On the other hand, if no edit instruction is input (NO in S111), the process proceeds to S117.

When an editing instruction is input (YES in S111), the control unit 10 displays an editing screen (not shown) for enabling editing of the face impression image KG based on an instruction from the user (sealing person). 12 (S113).

The editing screen includes, for example, a seal impression image display area similar to the confirmation screen 30 (see FIG. 6B), a color density (brightness) of the face imprint image KG, and the thickness of lines forming the face imprint image KG. an editing completion icon (editing completion instruction inputting section) for inputting an instruction to complete editing (also referred to as an "editing completion instruction"); Consists of The face imprint image KG displayed in the imprint image display area 30a of the confirmation screen 30 is displayed in the imprint image display area of the editing screen.

The user (sealing person) operates the operation input unit 13 to perform adjustment (change instruction input) using a control bar (not shown) on the edit screen, thereby displaying the face imprint image KG on the edit screen (imprint image display). area) can be edited. That is, the control section 10 is configured to edit the face seal image KG based on the input from the control bar on the editing screen. The processing related to the editing of the face impression image KG performed by the control unit 10, including the processing of S113, corresponds to an example of the "editing means" of the present invention.

In this embodiment, the color shading, line thickness, etc. of the face seal image KG are editable contents (edit items), but the contents are arbitrary. For example, in addition to standard content such as color shading (brightness), it is also possible to change (edit) facial expressions included in the face imprint image displayed on the editing screen (imprint image display area). It is possible (expression changing means). Specifically, for example, by performing input using a predetermined facial expression changing tool (tool bar, control bar, etc.) included in the editing screen, the mouth corners of the face included in the face imprint image can be changed, and the angle and opening of the eyes can be changed. The expression of the face can be changed, such as by changing the condition. As a result, it is possible to correct the facial expression included in the facial impression image without redoing the photographing.

Then, the user (sealer) clicks an editing completion icon (not shown) on the editing screen when finishing editing the face impression image KG. As a result, an edit completion instruction is input (YES at S115). On the other hand, if the edit completion instruction is not input after the edit screen is displayed (NO in S115), the process waits until the edit completion instruction is input.

When the editing completion instruction is input (YES in S115), the control section 10 displays the confirmation screen 30 (see FIG. 6B) again on the display section 12 (S116). At this time, the edited (edited) face impression image KG is displayed in the seal impression image display area 30 a of the confirmation screen 30 .

Then, with the confirmation screen 30 displayed on the display unit 12 (S109 or S116), the control unit 10 determines whether or not a seal instruction has been input (S117).

The user (sealer) clicks the seal icon 30d (see FIG. 6B) on the confirmation screen 30 when stamping with the face stamp image KG displayed in the stamp image display area 30a. Thus, a seal instruction is input (YES in S117). On the other hand, if the seal instruction is not input (NO in S117), the process returns to S110.

When the stamping instruction is input (YES in S117), the control unit 10 displays the face stamp image in the designated stamping column (stamping location) of the electronic document being displayed on the display unit 12 (see FIG. 5A). KG is affixed (S119), and the stamping process ends. The confirmation screen 30 is erased along with the attachment (stamping) of the face impression image KG. FIG. 5(B) shows an example of the stamp field to which the face stamp image KG is pasted.

As shown in the figure, the face impression image KG (see FIG. 6(B)) displayed in the seal impression image display area 30a of the confirmation screen 30 is pasted in the seal column in accordance with the size of the seal column. (imprinted). The process of S119 of pasting (sealing) the face impression image in the stamping column corresponds to an example of the "sealing means" of the present invention.

[Imprint processing]
Next, the imprinting process (S107) performed in the stamping process (S100) will be described with reference to the flow chart shown in FIG.

As shown in FIG. 4, in the imprint processing (S107), first, the captured image captured in S105 is acquired (S201). As described above, the captured image is stored (saved) in the captured image storage area as a raster image, so in S201, the captured image is read out from the captured image storage area. An example of the captured image (captured image SG) is shown in FIG.

Next, in S203, the photographed image acquired in S201 is converted into a binary image in vector format (S203). That is, the photographed image is simplified to a black and white image. An example of the converted binary image (binary image NG) is shown in FIG. 7B.

Here, when an actual seal is pressed onto a paper surface, the imprint appears as a colored material such as ink pad adhered to the stamp surface is transferred to the paper surface, and its appearance is usually the same as the color of the paper surface (for example, white). There are two colors, the color of the coloring material (for example, vermilion). In order to resemble the appearance of the actual seal impression, the raster format photographed image (see FIG. 7(A)) is converted into a vector format binary image (see FIG. 7(B)).

Next, in S205, in the binary image after the conversion in S203, that is, in the black and white binary image, the black portion is changed to vermilion (S205). Specifically, the black portion (black portion) of the binary image NG shown in FIG. 7B is made vermillion. The vermilion color is used to express the color of the seal imprinted using vermilion ink.

When the black portion is changed to another color, the changed color (that is, the color of the seal impression) may be a color other than vermilion, such as red or blue. Alternatively, the user (person who seals the seal) may be allowed to select the color of the seal impression. In this case, for example, "imprint color" is provided as editable content (editing item) on the above editing screen, and the user (sealer) selects from a plurality of predetermined colors such as vermilion, red, blue, and green. can be configured to select a desired color and change to the selected color. In other words, "color change" can be included in the editing of the face seal image by the editing means. By doing so, it is possible to increase the color variation of the face stamp image.

Alternatively, the white portion and the black portion of the binary image may be inverted, and the black portion after the inversion may be changed to another color (red, etc.). This makes it possible to express the face impression image like a so-called reverse-engraved seal impression (white seal impression).

Next, in S207, mask processing is performed to extract a portion to be displayed as a face imprint image (also referred to as a “imprint portion”) from the binary image (also referred to as a “color-changed image”) subjected to color change in S205 ( S207). Mask processing is image processing for displaying (extracting) only a specific portion (range) of an image and not displaying other portions. As the mask processing (mask function), for example, a clipping mask or layer mask method can be used.

In this embodiment, a color-changed image obtained by changing the black portion of the binary image NG shown in FIG. (that is, mask processing is performed on the color-changed image) to generate the face impression image KG shown in FIG. 7(C).

In this embodiment, the shapes of the “display (extraction) range” and the “seal impression frame (frame image)” represented in the mask image are both “circular”. Also, the color of the seal imprint frame displayed on the mask image is the same color as the color change in S205 (red in this embodiment). It should be noted that the shape and color of the mask image can be appropriately changed according to the specifications (imprint shape, color, size, etc.) of the face imprint image KG to be generated.

Alternatively, the seal imprint frame (frame image) may be prepared as an image separate from the mask image, without representing it in the mask image. In this case, by synthesizing the masked color-changed image (the color-changed image in which the seal impression portion is displayed and the other portions are not displayed) and the frame image representing the seal impression frame, the image shown in FIG. can obtain the face seal image KG shown in FIG.

When the face impression image KG is generated as described above, the generated face impression image KG is displayed in the seal impression image display area 30a of the confirmation screen 30 as shown in FIG. 6B (S109). . Then, the face impression image KG displayed in the seal impression image display area 30a can be pasted (sealed) to an electronic document or the like (see FIG. 5).

[Action and effect of the embodiment]
According to the electronic seal stamp system of the present embodiment described above, the face of the user (person who seals the seal) is taken as an object to be photographed, and the seal impression processing (S107) is performed based on the photographed image photographed by the camera 15 (processing of S105). The face seal impression image generated by the application includes the facial expression of the user (sealer). Therefore, it is possible to express the feeling (enthusiasm, emotion, etc.) of the sealer with the seal impression image. Then, by pasting (sealing) the face imprint image onto an object to be stamped such as an electronic document, etc., unique communication is achieved by conveying the stamper's feelings to the other party (for example, an approver, etc.) through the expression contained in the face imprint image. becomes possible.

In particular, between users of the terminal device 1 in which the electronic seal stamp software according to the present embodiment is installed, an electronic document or the like to which each person's face stamp image is pasted (sealed) can be sent via a network by e-mail, workflow, or the like. By exchanging through the media, it is possible to convey each other's thoughts from the facial expressions that appear in each other's facial impression images. As a result, it becomes possible to provide the electronic seal stamp system with a function as a fresh and interesting new communication tool, and by extension, it becomes possible to compensate for the lack of communication that is a concern in remote work and the like.

Further, in this embodiment, the seal imprint processing (S107) applied to the photographed image obtained by photographing the face of the user (the sealer) is the processing of converting the raster format photographed image into a vector format binary image ( S203). Therefore, it is possible to make the appearance of the face impression image generated through the imprint processing resemble the actual seal impression. This makes it possible to enhance the reality of the face seal image as a seal impression.

Further, in this embodiment, the imprint processing (S107) applied to the photographed image obtained by photographing the face of the user (sealing person) is performed in addition to the above-described binary image conversion processing (S203). It includes processing (S205) for changing the black portion of the value image to vermilion. This makes it possible to make the appearance of the face seal image more similar to the actual seal impression.

Further, in this embodiment, the seal impression process (S107) applied to the photographed image obtained by photographing the face of the user (sealer) displays the face seal image from the above-mentioned binary image (color-changed image). It includes mask processing (S207) for extracting the range (seal impression portion). This makes it easy to deal with any stamp shape.

In this embodiment, the face impression image generated through the imprint processing (S107) can be edited based on instructions from the user (sealer) (S111-S115). Therefore, the user (sealer) can arbitrarily edit the face seal image before stamping. This makes it possible to correct or customize the face seal image.

In this embodiment, in the seal imprint processing (S107), the range (imprint portion) to be displayed as the face imprint image is extracted from the binary image (color-changed image) by mask processing (S207). A range (seal imprint portion) to be displayed as a face imprint image may be extracted from the photographed image acquired in (1) by mask processing. That is, before converting the photographed image into a binary image, the seal imprint portion is extracted from the photographed image by mask processing, and then the conversion to the binary image (S203) and the color change of the black portion (S205) are performed. may This also makes it possible to generate the face stamp image shown in FIG. 7(C).

In this embodiment, the process of changing the black portion of the binary image to vermilion (S205) is performed in the imprint processing (S107), but the color change may not be performed. That is, the process of S205 may not be included. In this case, the color of the face imprint image (imprint color) is black. Also, it is possible to configure so that the user (sealer) can select whether or not to perform the processing of S205, that is, whether or not to change the color of the black portion. This makes it possible to increase the degree of freedom in selecting the color of the face imprint image (imprint color).

In this embodiment, the face (expression) of the user (sealing person) included in the photographed image is converted into the imprint as it is. A portrait image or an avatar image may be generated, and a face impression image may be generated by converting the portrait image or avatar image into a seal impression. In other words, the stamping process (S107) may include a process of generating a portrait image or an avatar image of the user (sealing person) from the photographed image acquired in S201. This makes it possible to add interest to the face seal image.

Next, a modified example of the embodiment described above will be described. In addition, below, it demonstrates centering on a different point from an Example, and abbreviate|omits description about the point which is common with an Example.

[Modification 1]
Modification 1 has a function (so-called “recommendation function”) for displaying (presenting) candidates for edited (edited) face imprint images in advance when editing a face imprint image generated through the imprint processing (S107). ”). This function is an example of the "presentation means" of the present invention.

In Modified Example 1, the control unit 10 executes the stamping process (S100a) shown in FIG. 8 instead of the stamping process (S100) shown in FIG. In this stamping process (S100a), if an edit instruction is input (YES in S111), an edited image ("edited image") is generated (S112), and the generated edited image is displayed on the display unit 12 together with the editing screen (S113).

The editing pattern defines the specific editing content (editing mode) of image editing. For example, a plurality of types of editing patterns are prepared in advance, such as darkening or lightening the color of the original image, changing the type of color, and thickening or thinning the line. This edit pattern is stored and managed in the storage unit 11 . Editing patterns can include patterns of various facial expressions such as a normal face, a smiling face, a sad face, and an angry face. In this case, it is possible to provide stepwise different patterns for each facial expression, such as the degree of laughter and the degree of regret.

When an editing instruction is input (YES in S111), the control unit 10 edits the face imprint image generated in S107 based on one or more of a plurality of predetermined editing patterns. An edited image (not shown) is generated (S112). For example, an image with a darker color than the original face impression image, or an image in which the facial expression included in the original face impression image is changed to a smiling face, a bursting smile, a sad face, or the like is generated. The number of edited images generated at this time may be one or more. Then, the generated edited image is displayed together with the editing screen (S113).

When the edited image is generated and displayed (presented), the edited image is displayed (presented) so that the user (sealer) can select it. At this time, if there are a plurality of edited images, the edited images are displayed (presented) so that the user (sealer) can select a desired edited image from among the plurality of edited images. When the user (sealing person) selects an edited image on the edit screen, the content of the selected edited image is displayed in the face imprint image generated in S107 (displayed in the imprint image display area of the edit screen). face stamp image). In this way, it is possible to save the user (person who seals) the trouble of editing.

According to Modification 1 described above, it is possible to improve convenience when a user (person who seals) edits the generated face seal impression image.

In the modified example 1, an edited image is generated and presented based on the face imprint image generated in S107. In this case, an edited image corresponding to the editing pattern including the facial expression pattern may be generated based on the captured image captured in S105 and presented. This is because the photographed image also includes the facial expression of the user (person who signs the seal).

In this case, the edited image generated based on the photographed image is displayed on the editing screen, and the edited image is compared with the face impression image displayed in the impression image display area of the editing screen. The configuration may be such that input related to editing (change instruction input) can be performed. This also makes it possible to improve the convenience of editing.

[Modification 2]
Modification 2 recognizes the facial expression of the photographed user (sealing person) (the user's face included in the photographed image) as the stamping process (S100) executed by the control unit 10, and based on the recognition result, It includes a process of generating a seal impression image by means of a process, and affixing (sealing) the generated seal impression image to an object to be sealed such as an electronic document. It should be noted that Modification 2 is also applicable to Modification 1. FIG.

The seal impression image generated by the control unit 10 in Modification 2 includes characters such as the user's (sealer's) surname and name, and is generated separately from the face impression image according to the above-described embodiment and Modification 1. It is a thing. Hereinafter, in order to distinguish from the face imprint image described above, the imprint image including characters such as the surname and the first name according to Modification 2 will also be referred to as a "character imprint image".

Modification 2 differs from the embodiment in at least the stamping process (S107) of the stamping process (S100) shown in FIG.

Here, in Modified Example 2, it does not matter whether the aforementioned face stamp image is included or not. When the face imprint image is included, the character imprint image is pasted (stamped) together with the face imprint image described above (to be stamped) on the stamping target. (to affix a seal). Also, when the face imprint image is not included, the face imprint image in S109 and S116 in the sealing process (S100) shown in FIG. 3 is replaced with the character imprint image. When the face stamp image is not included, the processing (S111 to S116) related to the editing of the stamp image may or may not be performed.

In Modified Example 2, the control unit 10 executes the imprint processing (S107a) shown in FIG. 9 instead of the imprint processing (S107) shown in FIG. In this stamping process (S107a), first, a photographed image is obtained (S301). The processing of S301 is the same as S201 in the imprint processing (S107) of the embodiment.

Next, in S303, facial expressions of the user (sealer) included in the photographed image acquired in S301 are recognized (S303). Specifically, facial expressions are recognized based on the corners of the mouth and the angles of the eyes included in the captured image, and whether the facial expressions are, for example, a smile or a sad face is specified. It can be said that the control unit 10 that executes the process of S303 functions as "facial expression recognition means" or "facial expression specifying means". Note that facial expressions that can be recognized (specified) in S303 are not limited to smiles and disappointed faces.

Next, in S305, character data (also referred to as "surname data") representing the surname of the user (sealer) is acquired (S305). Here, for example, when user information (user information) as a user of the electronic seal stamp system is managed in advance in the storage unit 11 or the like, based on the user's surname included in the user information, the user (sealer) ) to get the last name data. Alternatively, at the start of use of the electronic seal stamp system or the start of execution of the sealing process, the last name of the user (sealing person) is required to be entered, and based on the last name entered, the surname data of the user (sealing person) is obtained. do. It can be said that the control unit 10 that executes the process of S305 functions as "character data acquisition means" or "surname data acquisition means".

Next, in S307, a character imprint image is generated based on the facial expression included in the photographed image recognized (identified) in S303, that is, the facial expression of the user (sealing person) and the surname data acquired in S305. Generate (S307). Here, a character image is generated (fontized) in which the expression recognized in S303 is reflected in the surname data (character data), and the character image and the seal impression frame prepared in advance (stored in the storage unit 11) are generated. image (frame image) to generate a character seal image. It can be said that the control unit 10 that executes the process of S307 functions as "seal impression image generating means" or "generating means".

FIG. 10 shows an example of the character imprint image (character imprint image MG) generated in S307. The character imprint image MG shown in FIG. (B) is a character imprint image MG2 when the facial expression recognized (specified) in S303 is a disappointing face (disappointing pattern).

According to the modified example 2 described above, it is possible to express the feeling of the sealer not only by the face seal image but also by the character seal image, so that the sealer's feelings can be conveyed to the other party. In addition, it is possible to seal with a novel character imprint image that cannot be expressed with the conventional electronic seal stamp software (electronic seal stamp system) that imprints the user's last name as a imprint image. Therefore, according to Modification 2 as well, it is possible to provide the electronic seal stamp system with a function as a novel and interesting new communication tool.

In modification 2, when the above-described face imprint image is stamped together with the character imprint image, for example, the size of the character imprint image is made smaller than the size of the face imprint image, and the periphery of the face imprint image (for example, the lower right) is printed. The character imprint image may be pasted on the character imprint image directly, or the character imprint image may be pasted on the face imprint image around the character imprint image (for example, in the lower right corner) by making the size of the character imprint image larger than the size of the face imprint image. and the face impression image can be stamped in different sizes. In this way, it is possible to perform imprinting in a well-balanced manner.

The facial expression recognized in S303 may also be reflected in the shape of the seal imprint frame (frame image). That is, in S307, a frame image reflecting the facial expression recognized in S303 may be generated, and a character seal impression image including the frame image may be generated. By doing so, it is possible to increase the variations of the character impression image that expresses the feeling of the sealer.

Further, in the modified example 2, the last name is targeted for imprinting.

Further, in Modified Example 2, the character imprint image is generated based on the surname data acquired in S305. On the other hand, for example, if conventional electronic seal stamp software for stamping a user's surname as a stamp image is installed in the terminal device 1 and the stamp image is already managed in the storage unit 11 or the like, the existing stamp image may be transformed based on the facial expression recognized in S303 to generate a character seal impression image. In this way, it is possible to add (upgrade) the function of expressing the feeling of the sealer by utilizing the existing seal impression image.

The electronic seal stamp system of Modification 2 described above can be specified as follows.
a photographing means capable of photographing the face of the sealer;
facial expression recognition means capable of recognizing facial expressions included in the captured image captured by the imaging means;
generating means for generating a seal impression image reflecting the facial expression recognized by the facial expression recognition means;
An electronic seal stamp system, comprising: a stamping means for affixing the stamp image to a stamping position to be stamped displayed on a predetermined display screen.

In the above embodiment and modified example, the control unit 10 of the terminal device 1 installed with the electronic seal stamp software performs the sealing process (S100, S100a) and the imprint process (S107, S107a). In response to this, the control unit of a server device (for example, a WEB server) managed by a business operator that provides the service of the electronic seal stamp system performs the above-described stamp processing (S100, S100a) and imprint processing (S107, S107a). It can also be configured to do so.

Specifically, a terminal device used by a user (sealing person) and a server device are connected via a network, and a sealing process (S100, S100, S100a) and imprint processing (S107, S107a) are performed, and a facial imprint image or character imprint image can be imprinted on an electronic document or the like displayed on the display screen of the terminal device. Also by this, it is possible to obtain the same effects as those of the above embodiments and modifications. Moreover, it is possible to improve the spreadability of the system.
