FIG. 1 is a block diagram showing a configuration of an album creation support device according to an embodiment of the present invention. As shown in the figure, the album creation support device 100 of this embodiment has an external interface (I / F) 110, an input unit 120, a display unit 130, a storage unit 140 for storing a reference image, and a storage unit for storing a captured image. It is configured to include a unit 150 and a control unit 160 that controls each unit.

The external I / F 110 enables wired or wireless connection with other electronic devices (eg, smartphones, digital cameras, etc.). Further, the external I / F 110 enables connection to a server or the like on the network via a wired or wireless communication means.

The input unit 120 receives the input from the user and provides the input unit 120 to the control unit 160. The input unit 120 is not particularly limited, and includes, for example, a keyboard, a mouse, a voice input module, a touch panel, and the like. The display unit 130 is not particularly limited, but includes, for example, a liquid crystal display, an organic EL, and the like, and displays a photograph and the like for editing an album.

The storage unit 140 stores a reference image that serves as a reference (comparison source) when performing face recognition. The reference image can be acquired from another electronic device (smartphone, personal computer, digital camera, etc.) via an external I / F 110, and the acquired reference image is stored in the storage unit 140. One reference image includes one or more facial images unique to a person. FIG. 2 shows an example of data configuration of the storage unit 140. The reference identification identifies a reference image, and the reference image includes a face image peculiar to a person. That is, reference identification is synonymous with user identification. In the example of FIG. 2, the reference identification U1 includes one or more face images U1-1, U1-2, ..., U1_n of the user U1, and the reference identification U2 is one or more face images U2_1 of the user U2. U2_2, ..., U2_n is included, and the reference identification U3 includes one or more facial images of the user U3. The plurality of face images can improve the accuracy of face recognition by including, for example, face images taken from different directions, face images wearing masks and hats, face images having different brightness, and the like. .. In this way, the reference images of the plurality of users U1, U2, ..., And Un are registered in advance in the storage unit 140.

The storage unit 150 stores an captured image to be compared with the reference image. The captured image can be acquired from another electronic device (smartphone, personal computer, digital camera, etc.) via an external I / F 110, and the acquired captured image is stored in the storage unit 150.

FIG. 3 shows an example of data configuration of the storage unit 150. The imaging identification identifies the captured image, and here, one captured image is one photograph. One captured image can include, as attribute information, identification of the person who captured the captured image (or identification of the person who provided the captured image), the date and time of imaging, and an event related to the captured image. In the example of FIG. 3, the image pickup identification P1 has the same meaning as the photograph P1, and the attribute information of the photograph P1 includes the imager identification, the image capture date and time, the event, and the storage destination of the image capture image.

The control unit 160 controls the overall operation of the album creation support device 100. The control unit 160 is configured using hardware and / or software, and in some embodiments, the control unit 160 includes a microprocessor, a microcontroller including a ROM / RAM, an image processor, an AI processor, and a digital signal processor (DSP). ) Etc. can be included.

In this embodiment, the control unit 160 includes an album creation support function 200 as shown in FIG. 1 (B). The album creation support function 200 includes a similarity calculation unit 210, a photo selection unit 220, a threshold value determination unit 230, and an album editing unit 240.

The similarity calculation unit 210 compares the captured image stored in the storage unit 150 with the reference image stored in the storage unit 140, and performs face recognition of the person captured in the captured image (photograph). Preferably, the similarity calculation unit 210 utilizes AI (artificial intelligence) technology to quantitatively calculate the degree to which the person captured in the captured image matches the face image of the reference image, that is, the similarity.

For example, assuming that the captured image is a photograph P1, a plurality of persons OB1 to OB7 are captured in the photograph P1 as shown in FIG. The similarity calculation unit 210 analyzes the characteristics of the image data of the photograph P1, extracts the face images of the seven people OB1 to OB7, and stores the extracted face images of the seven people OB1 to OB7 in the storage unit 140. Face recognition of seven persons OB1 to OB7 is performed by sequentially comparing with the stored reference image, and the degree of similarity is calculated.

FIG. 5 shows an example of the similarity calculation result of Photo P1. The similarity calculation unit 210 generates the coordinates where the face images of the recognition targets OB1 to OB7 are located, the similarity with the reference image, and the reference identification, respectively. For example, the coordinates where the face image of the recognition target OB1 is located are (x1, y1), indicating that the recognition target OB1 is 80% similar to the reference identification U3 (that is, the user U3). This similarity of 80% means the maximum among all the reference images compared with the recognition target OB1. Similarly, the coordinates where the face image of the recognition target OB2 is located are (x2, y2), indicating that the recognition target OB2 is 75% similar to the reference identification U4 (that is, the user U4). This similarity of 75% means the maximum among all the reference images compared with the recognition target OB2. The same is shown for other recognition targets OB3 to OB7.

The similarity calculation unit 210 has a function of displaying the similarity calculation result on the display unit 130 as one function. For example, the user can specify a photo via the input unit 120 and display the similarity calculation result of the specified photo on the display unit 130. FIG. 6 is a display example of the similarity calculation result of Photo P1. As shown in the figure, an index TG showing the similarity calculation result shown in FIG. 5 is displayed in the vicinity of the persons OB1 to OB7 in the photograph P1. The user can recognize the situation of similarity through this screen.

The calculation result of the similarity calculation unit 210 is provided to the photo selection unit 220. The photo selection unit 220 compares the threshold value Th provided by the threshold value determination unit 230 with the degree of similarity, and selects a photo having a degree of similarity equal to or higher than the threshold value Th. The photo selection unit 220 further has a function of filtering photos for each reference identification (user identification). FIG. 7 shows an example in which photographs having a similarity equal to or higher than a threshold value are classified by reference identification. For example, the photographs having a similarity equal to or higher than the threshold value for the reference identification U1 are P1, P5, P8, P10, etc., and the photographs having the similarity equal to or higher than the threshold value for the reference identification U2 are P1, P3, P4, P7. And so on.

The user can specify reference identification to be filtered through the input unit 120. For example, when the user specifies the reference identification U2, the photo including the reference identification U2 is selected, and the photo not including the reference identification U2 is not selected. Further, the photo selection unit 220 can also filter the selected photos by using the metadata of the captured image stored in the storage unit 150. For example, by specifying the imager identification by the user, a photograph corresponding to the specified imager identification is selected, or by specifying an imaging period, a photograph having an imaging date and time corresponding to the imaging period is selected. It is also possible to select the photo corresponding to the event by setting the item or specifying the event.

The photo selected by the photo selection unit 220 is provided to the album editorial unit 240. The album editing unit 240 displays the selected photo on the display unit 130 and enables the user to edit the album. In album editing, for example, one or more templates are prepared, and the user can easily lay out a photo by using the templates. It is also possible to enlarge, reduce, rotate, etc. the photo as needed. The album editorial unit 240 can also convert each page of the created album into print data and have the printer print it via the external I / F 110.

Further, the control unit 160 stores the reference identification (user identification) for identifying the reference image in the storage unit 140 as metadata or attribute data (see FIG. 2).

Further, a plurality of captured images are captured via the external I / F 110 (S110), and the control unit 160 stores the captured captured images in the storage unit 150. The control unit 160 may process the captured image into a constant size or resolution to normalize the captured image. Further, the control unit 160 stores information such as imaging identification, imager identification, imaging date and time, and event for identifying the captured image in the storage unit 150 as metadata or attribute data (see FIG. 3).

Next, the user inputs an album editing instruction via the input unit 120 (S120), and then specifies reference identification (user identification) via the input unit 120 (S130). That is, the person to be edited in the album is specified. The reference identification is not limited to one, and may be a plurality of designations.

Next, the similarity calculation unit 210 compares the reference image with the captured image, authenticates the face of the recognition target of the captured image, and calculates the similarity (S140). Next, the photo selection unit 220 selects a photo having a similarity equal to or higher than the threshold value and includes the designated reference identification (S150), and the album editing unit 240 displays the selected photo on the display unit 130. Display (S160). The user edits the album using the photograph displayed on the display unit 130 (S170).

FIG. 9A is a display example of the photograph selected by the reference identification U1. On the screen 132 of the display unit 130, reduced images or thumbnail images of the selected photographs P1, P5, P8, P10 and the like are displayed, and the number of selected photographs (85) is displayed. When the user selects the photo P1, the enlarged photo P1 is displayed. Further, the threshold value adjustment button 134 is displayed on the screen 132. The currently set threshold value (80%) is displayed on the threshold value adjustment button 134, and an increase / decrease input button for increasing or decreasing the threshold value is displayed on the left and right of the threshold value adjustment button 134. The user can increase or decrease the threshold value by touching the increase / decrease input button in consideration of the number of selected photographs. FIG. 9B shows an example in which the user changes the threshold to 90%. As a result, the photographs P8, P10, P18, P25 and the like are selected, and the number of selected photographs is reduced to 40. The user can adjust the number of photos used in the album by adjusting the threshold value as appropriate.

As described above, according to this embodiment, since the captured image (photograph) having a high degree of similarity is automatically selected from the plurality of captured images by using face recognition, the captured image is selected when creating an album. The work efficiency for selection can be greatly improved.

Next, a second embodiment of the present invention will be described.

FIG. 10 is a flow for explaining the operation of the second embodiment. In the second embodiment, steps S200 and S210 are different from the steps shown in FIG. 8, and the other steps are the same as those in FIG. .. In the second embodiment, the threshold value determination unit 230 receives the number of photographs selected by the photo selection unit 220, determines whether or not the number of photographs is a certain value or more (S200), and when the number is a certain value or more. Considers that the number of selected photographs is too large, and increases the current threshold value by ΔTh (S210). In response to this threshold change, the photo selection unit 220 reselects the photo based on the changed threshold (S150). This loop is repeated until the number of selected photos falls below a certain value.

As described above, according to the present embodiment, the threshold value can be automatically adjusted so that the number of selected photographs does not exceed the upper limit value, and the convenience of the user can be improved. The upper limit of the number of photographs and the threshold increase amount ΔTh are set in advance in the threshold determination unit 230.

As a modification of this embodiment, it is also possible to set a lower limit value for the number of photographs and automatically adjust the threshold value so that the number of photographs is larger than the lower limit value. In this case, if the number of selected photographs is below the lower limit, the threshold determination unit 230 reduces the current threshold value by ΔTh, and the photo selection unit 220 reselects the photographs based on the changed threshold value. ..

As a further modification, both the upper limit value and the lower limit value of the number of photographs may be set, and the threshold value may be automatically adjusted so that the number of photographs is between the upper limit value and the lower limit value. As a result, it is possible to automatically select a photo according to the number of photos required for editing the album.

In the third embodiment, steps S220 and S230 are different from the steps shown in FIG. 8, and the other steps are the same as those in FIG. .. In the third embodiment, the threshold determination unit 230 receives the number of photos selected by the photo selection unit 220, and determines whether or not the number of album pages calculated from the number of photos is equal to or greater than a certain value (S220). ), If it is equal to or more than a certain value, it is considered that the number of selected photographs is too large, and the current threshold value is increased by ΔTh (S230). In response to this threshold change, the photo selection unit 220 reselects the photo based on the changed threshold (S150). This loop is repeated until the number of selected photos falls below a certain value.

The threshold value determination unit 230 includes a mathematical formula or a table that defines the relationship between the number of photographs and the number of pages in the album. For example, the upper limit of the number of photographs (Max = M × P) is set from the number M of photographs that can be laid out on one page and the maximum number of pages P that constitute an album. Further, in one embodiment, when the user selects a template to be used for the layout of photographs, the number of photographs that can be laid out on one page may be calculated based on the template.

As described above, according to the present embodiment, the threshold value can be automatically adjusted so that the number of selected photographs does not exceed the upper limit of the number of pages of the album, and the convenience of the user can be improved.

As a modification of this embodiment, it is also possible to set a lower limit value for the number of pages in the album and automatically adjust the threshold value so that the number of photographs is larger than the lower limit value. In this case, if the number of selected photographs is below the lower limit, the threshold determination unit 230 reduces the current threshold value by ΔTh, and the photo selection unit 220 reselects the photographs based on the changed threshold value. ..

As a further modification, both the upper limit and the lower limit of the number of pages of the album may be set, and the threshold may be automatically adjusted so that the number of photographs is between the upper limit and the lower limit. As a result, it is possible to automatically select a photo according to the number of photos required for editing the album.
