1. 1. Hardware configuration of image processing device

FIG. 1 shows a hardware configuration of an image processing apparatus according to an embodiment of the present disclosure.

The image processing device 10 according to the present disclosure may be an information processing device (personal computer, tablet computer, smartphone, etc.), an image forming device (MFP, Multifunction Peripheral), or the like. In the following description, the image processing device 10 is an image processing device.

The image processing device 10 includes a control circuit 100. The control circuit 100 is composed of a CPU 11a (Central Processing Unit) which is a processor, a RAM 11b (Random Access Memory), a ROM 11c (Read Only Memory) which is a memory, a dedicated hardware circuit, and the like, and is an overall image processing device 10. Controls motion control. The CPU 11a loads the information processing program stored in the ROM 11c into the RAM 11b and executes it. The ROM 11c fixedly stores programs, data, and the like executed by the CPU 11a. ROM 11c is an example of a non-transient computer-readable recording medium.

The control circuit 100 includes an image reading unit 12 (image scanner), an image processing unit 14 (including a GPU (Graphics Processing Unit)), an image memory 15, an image forming unit 16 (printer), and an operation unit 17 (including a display unit 17a). It is connected to a large-capacity non-volatile storage device 18 such as a touch panel), an HDD (Hard Disk Drive) or SSD (Solid State Drive), a facsimile communication unit 19, a network communication interface 13, and the like. The control circuit 100 controls the operation of each of the connected parts and transmits / receives a signal or data to / from each part. The operation unit 17 (touch panel) is a form of an input device, and a voice input device including a microphone may be provided as the input device.

2. 2. Functional configuration of image processing equipment

FIG. 2 shows a functional configuration of an image processing device.

In the control circuit 100 of the image processing device 10, the CPU 11a loads the information processing program stored in the ROM 11c into the RAM 11b and executes it, so that the login unit 101, the signature acquisition unit 102, the document data acquisition unit 103, and the composite data creation unit are executed. It operates as 104 and the composite data output unit 105.

3. 3. Operation flow of image processing device

FIG. 3 shows a first operation flow (overall operation) of the image processing apparatus.

The login unit 101 accepts the user's login (step S101).

FIG. 4 shows an example of a login screen.

For example, the login unit 101 displays the login screen (FIG. 4) on the display unit 17a (touch panel). The login unit 101 determines the user name and password entered by the user via the operation unit 17. If the combination of the entered user name and password matches the combination registered in advance locally or on the server, the login unit 101 authenticates the user and accepts the login.

If the login is successful, the signature acquisition unit 102 determines whether or not the signature data 110 is stored in the non-volatile storage device 18 (step S102). The signature data 110 is electronic image data of a handwritten signature. Typically, the signature data 110 is stored in association with the logged-in user's identifier (eg, user name) (step S102, YES). On the other hand, if the signature data 110 is not stored in association with the identifier (for example, the user name) of the logged-in user (step S102, NO), the signature acquisition unit 102 newly creates the signature data 110 and stores the signature data 110. Store in 18 (step S103). The operation flow when the signature acquisition unit 102 creates the signature data 110 will be described below.

FIG. 5 shows a second operation flow (operation at the time of creating signature data) of the image processing apparatus.

FIG. 6 shows an example of the signature input screen.

For example, the signature acquisition unit 102 displays the signature input screen (FIG. 6) on the operation unit 17 (touch panel) including the display unit 17a. The signature input screen (FIG. 6) includes a designated area (frame). The user inputs a handwritten signature to the operation unit 17 using a stylus or the like. The signature acquisition unit 102 detects the handwritten signature entered by the user via the operation unit 17 (step S201).

FIG. 7 is an example of an image before the pixel is transparently processed.

The signature acquisition unit 102 acquires the pixel value in the designated area (frame) (step S202). This pixel value is a value before the pixel value is transparently processed. If the pixel value is not transparently processed, the pixel (black portion in FIG. 7) that does not include the signature is combined with the document. Therefore, the signature acquisition unit 102 transparently processes the pixels in the designated area that do not include the signature (step S203).

FIG. 8 is an example of an image after transparent processing of pixels.

Specifically, the signature acquisition unit 102 converts the α component (transparency) of a pixel not including a signature, which is composed of an RGBA (Red, Green, Blue, Alpha) color space, into 0 as a transmission process.

The signature acquisition unit 102 extracts only the signature portion (pixels whose α component is not 0) in the designated area. The signature acquisition unit 102 associates the extracted set of pixels with an identifier (for example, a user name) of the logged-in user, and stores it in the storage device 18 as signature data 110 (electronic image data of a handwritten signature) ( Step S204).

FIG. 9 shows an example of the signature data confirmation screen.

When the signature data 110 is stored, the signature acquisition unit 102 may display the signature data confirmation screen (FIG. 9) including the signature data 110 on the display unit 17a so that the user can confirm the signature data 110.

See FIG. 3 again. When the signature acquisition unit 102 creates and stores the signature data 110 (step S103), the login unit 101 once logs out the user (step S104). After that, the login unit 101 displays the login screen (FIG. 4) again and accepts the user's login (step S101). In this case, since the signature data 110 is stored (step S102, YES), the process proceeds to step S105 or lower.

FIG. 10 shows an example of a scan start screen.

The document data acquisition unit 103 displays the scan start screen (FIG. 10) on the display unit 17a (touch panel). The user sets the document in the image reading unit 12 (image scanner) and operates the start button on the scanning start screen (FIG. 10). The document data acquisition unit 103 physically detects the document set in the image reading unit 12 (image scanner) and detects the operation of the start button (step S105). When the document data acquisition unit 103 physically detects the document, the document data acquisition unit 103 optically scans the document to obtain the document data (step S106).

The composite data creation unit 104 reads the signature data 110 from the storage device 18 and creates the composite data by synthesizing the signature data 110 with the document data (step S107). The operation of the synthetic data creation unit 104 to create synthetic data will be described in detail later.

The composite data output unit 105 converts the composite data into bitmap data and prints it using the image forming unit 16 (printer) (step S108).

FIG. 11 shows an example of a composite data output screen.

The composite data output unit 105 displays the composite data output screen (FIG. 11) on the display unit 17a (touch panel). When saving the composite data, the user operates the save button on the composite data output screen (FIG. 11). When the composite data output unit 105 detects that the save button has been operated (step S109, YES), the composite data output unit 105 converts the composite data into a PDF file, sends the created PDF file to a server device (not shown), and saves it. (Step S110). On the other hand, if the composite data output unit 105 times out without detecting that the save button has been operated, the process ends (step S109, NO).

4. Operation flow of the composite data creation unit

FIG. 12 shows a third operation flow (operation at the time of creating composite data) of the image processing apparatus.

The operation (step S107) in which the composite data creation unit 104 creates the composite data by synthesizing the signature data 110 with the document data will be described in detail.

The composite data creation unit 104 acquires the size (p_width, p_height) of the document data area (document area). The document area may be the entire area of the document data (for example, an area of A4 size) or an area excluding the margin for printing. The synthetic data creation unit 104 reads out the specific metadata 120 from the storage device 18 (step S301). The metadata 120 is used to determine the area where the signature data is combined. Metadata 120 is a general term such as "name".

The composite data creation unit 104 recognizes the text included in the document area by optical character recognition. The synthetic data creation unit 104 may recognize all the texts included in the document area in order from the beginning (from the top), or the area (bottom) in which the metadata 120 (“name” in this example) is likely to be included. The text contained in (half) may be recognized (step S302). The synthetic data creation unit 104 detects a specific text (text representing the metadata 120 “name”) from the text included in the document area (step S303, YES).

The composite data creation unit 104 extracts an area (text area) including a specific text "name" from the document area. The edge of the text included in the text area may touch the outline of the text area (not shown), and the edge of the text may not touch the outline of the text area (FIG. 13).

FIG. 13 schematically shows an example of a text area including text.

The composite data creation unit 104 determines the position of the text area of the text area 200. The text area position is a coordinate position within the document area of the text area 200. In this example, the composite data creation unit 104 determines the coordinates (x1, y1) of the upper left start point 201 of the text area 200 and the coordinates (x2, y2) of the lower right end point 202 as the text area position. The composite data creation unit 104 may further determine, as the text area position, the coordinates (x1, y2) of the lower left vertex 203 of the text area 200 and the coordinates (x2, y1) of the upper right vertex 204.

The composite data creation unit 104 determines the text area size of the text area 200. The text area size is the size of the text area 200. In this example, the composite data creation unit 104 determines the width (n_width = x2-x1) and height (n_height = y2-y1) of the text area 200 as the text area size (step S304).

FIG. 14 schematically shows an example of the number of characters of the text included in the text area and the number of characters that can be included in the signature area.

The composite data creation unit 104 determines the number of characters (meta_n) of the text 210 "name" included in the text area 200. In this example, the number of characters in the text 210 "name" is (meta_n = 2). The composite data creation unit 104 calculates the ratio of the signature area to the text area 200 based on the number of characters (meta_n = 2) of the text 210 (step S305). The signature area is an area for arranging the signature data 110. Specifically, the composite data creation unit 104 sets the number of characters (area_n) of the signature data 110 to be arranged in the signature area / the number of characters (meta_n) of the text 210 as the ratio (r) of the signature area to the text area 200. .. That is, the ratio of the signature area to the text area 200 is (r = area_n / meta_n). For example, the number of characters in the signature data 110 may be 6 (area_n = 6). This is a typical Japanese name with 4 or 5 characters, taking into account the space between the surname and given name. The number of characters (area_n) in the signature data 110 may be variable. In short, the ratio of the signature area to the text area 200 means the ratio of the signature area required to synthesize the signature data 110 in a natural size with respect to the size (font size) of the text 210. For example, in the case of (meta_n = 2) and (area_n = 6), the ratio (r) of the signature area to the text area 200 is (r = 6/2 = 3).

FIG. 15 schematically shows an example of the number of characters of the text included in the text area and the number of characters that can be included in the signature area.

The composite data creation unit 104 determines the signature area position based on the text area position, the text area size, and the ratio. The signature area position is the coordinate position of the signature area 300 arranged in a specific positional relationship (to the right of the text area position) with respect to the text area position. In this example, the composite data creation unit 104 uses the coordinates (x2, y1) of the upper left start point 204 (common to the upper right vertex 204 of the text area 200) of the signature area 300 and the lower right end point 302 as the signature area position. Judge the coordinates (x_n, y2) of. The composite data creation unit 104 further, as the signature area position, the coordinates (x2, y2) of the lower left vertex 202 of the signature area 300 (common with the lower right end point 202 of the text area 200) and the coordinates of the upper right vertex 301. It may be determined as (x_n, y2). The x-coordinate (x_n) of the end point 302 at the lower right of the signature area 300 is (x_n = x2 + n_width * r). That is, the x-coordinate (x_n) of the end point 302 is "the x-coordinate (x2) of the end point 202 at the lower right of the text area 200" + "the value obtained by multiplying the width (n_width) of the text area 200 by the ratio (r)". There is (step S306).

The composite data creation unit 104 determines whether or not the determined signature area position exceeds the document area. Specifically, the composite data creation unit 104 determines whether or not the right end of the signature area 300 (x coordinate (x_n) of the lower right end point 302) exceeds the width (p_width) of the document area as the signature area position. Determine (step S307). When x_n> p_width holds, it means that the end point 302 of the signature area 300 exceeds (extrudes) from the document area (step S307, YES). On the other hand, when x_n ≦ p_width holds, it means that the end point 302 of the signature area 300 fits in (does not protrude) into the document area (step S307, NO).

The case where x_n> p_width holds, that is, the case where the end point 302 of the signature area 300 exceeds (extrudes) from the document area (step S307, YES) will be described. The composite data creation unit 104 reduces the signature area 300 by reducing the ratio (r). Specifically, the composite data creation unit 104 subtracts a specific value (for example, 0.5) from the number of characters (area_n) of the signature data 110 to obtain (area_n- = 0.5). As a result, in this example, since the number of characters of the signature data 110 is (area_n = 6), it becomes (area_n = 6-0.5 = 5.5) (step S308). As a result, the ratio of the signature area to the text area 200 (r = area_n / meta_n) is (r = 5.5 / 2 = 2.75). That is, the composite data creation unit 104 reduces the ratio (r) from (r = 3) to (r = 2.75) (step S305). As a result, the x-coordinate (x_n = x2 + n_width * r) of the end point 302 of the signature area 300 also becomes a smaller value when the ratio (r = 3) is used (step S306). In other words, the synthetic data creation unit 104 reduces the signature area 300 by reducing the ratio (r). The composite data creation unit 104 repeats the process for reducing the signature area 300 (steps S305 to S308) until x_n ≦ p_width holds (steps S307, NO).

The case where x_n ≦ p_width holds, that is, the case where the end point 302 of the signature area 300 fits in (does not protrude) into the document area (step S307, NO) will be described. The composite data creation unit 104 determines the size (width and height) of the signature area 300. The width of the signature area 300 is from the x coordinate (x_n) of the lower right end point 302 of the signature area 300 to the x of the lower left vertex 202 of the signature area 300 (common with the lower right end point 202 of the text area 200). It is the value (width = x_n-x2) obtained by subtracting the coordinates (x2). The height of the signature area 300 is the same value (height = y2-y1) as the height of the text area 200 (n_height = y2-y1) (calculated in step S304) (step S309).

FIG. 16 schematically shows an example of synthetic data.

The composite data creation unit 104 resizes the signature data 110 to a size that fits in the signature area 300 (when the signature area 300 is reduced in step S308, the reduced signature area 300). The composite data creation unit 104 arranges the resized signature data 110 at the signature area position in the document area (to the right of the text area 200 including the text 210), so that the resized signature data is placed in the document area of the document data. Synthesized data 400, which is the combined data of 110, is created. Specifically, the composite data creation unit 104 calls the image composite processing function drawImage (x, y, width, height) to create the composite data 400. Note that x is the x-coordinate of the left end of the composite region, y is the upper end y-coordinate of the composite region, width is the width of the composite region, and height is the height of the composite region (step S310).

5. Conclusion

A technique for synthesizing signature data, which is electronic image data of a handwritten signature, with document data is known. According to a known technique, a digital signature is created based on a handwritten signature entered by a user on a tablet terminal, a signature area in the document data is specified, and a digital signature is synthesized with the signature area in the document data. However, in this method, it is necessary to separately prepare a tablet terminal for inputting a handwritten signature, and it is necessary to specify a signature area in the document data.

According to another known technique, there is known an information processing device that assists a user in creating a document such as minutes by outputting handwritten characters on a display within a specified template range. However, in this method, it is necessary to prepare the data structure of the template in advance and set the output range.

(1) In view of the above circumstances, according to the present embodiment, the image processing apparatus 10 stores the signature data 110, which is electronic image data of the handwritten signature (step S102), and optically records the document. The text area 200, which is an area containing a specific text 210, is extracted from the document area, which is the area of the document data obtained by scanning (step S303), and the text area, which is the coordinate position in the document area of the text area 200, is extracted. The position, the text area size which is the size of the text area 200, and the number of characters of the text 210 included in the text area 200 are determined (step S304), and the ratio of the signature area to the text area 200 is determined based on the number of characters of the text area 210. Calculated (step S305), and based on the text area position, the text area size, and the ratio, the signature area position, which is the coordinate position of the signature area 300 arranged in a specific positional relationship with respect to the text area position, is determined. (Step S306), the signature data 110 is resized to a size that fits in the signature area 300 (step S309), and the resized signature data 110 is placed at the signature area position in the document area to be in the document area of the document data. The composite data 400, which is the composite data of the resized signature data 110, is created (step S310).

In this way, since the image processing device 10 calculates the size of the signature area based on the number of characters of the text 210 and the size of the text area, the signature data 110 is naturally (extremely large) with respect to the size (font size) of the text 210. It can be a size (not extremely small). Further, since the image processing device 10 arranges the signature area 300 in a specific positional relationship with respect to the text area position, the signature data 110 may be set to a natural (not extremely far) position with respect to the text 210. can. As a result, the image processing apparatus 10 can synthesize the signature data 110 into the document data at an appropriate position and size without the user manually specifying the position and size of the signature area 300.

Is resized to fit in the reduced signature area 300 (step S309). As a result, the signature data 110 can be made a natural (not extremely small) size with respect to the size (font size) of the text 210 while preventing the signature area 300 from exceeding (extruding) from the document area.

(3) According to the present embodiment, the signature area position is to the right of the text area position, and the image processing device 10 determines whether or not the right end of the signature area 300 as the signature area position exceeds the document area. to decide. As a result, the image processing apparatus 10 can synthesize the signature data 110 into the document data at an appropriate position without the user manually specifying the position of the signature area 300.

(4) According to the present embodiment, the image processing apparatus 10 extracts a text area 200, which is an area including a specific text 210, by optical character recognition. As a result, a general-purpose word such as "name" can be appropriately extracted, and as a result, the image processing apparatus 10 can appropriately extract the position of the signature area 300 without manually specifying the position of the signature area 300 (optically). The signature data 110 can be combined with the document data (near the text 210 detected by character recognition).

(5) According to the present embodiment, when the signature data 110 is not stored, the image processing device 10 detects the handwritten signature input by the user, and creates and stores the signature data 110 based on the detected handwritten signature and stores it. do. As a result, it is possible to newly create and store the signature data 110 and further create the synthetic data 400 in a series of operation flows without using separate hardware resources and software resources.
