In describing preferred embodiments illustrated in the drawings, specific terminology may be employed for the sake of clarity. However, the disclosure of this patent specification is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that have the same function, operate in a similar manner, and achieve a similar result.
An embodiment has an object to provide an opportunity to have entertainment based on a picture drawn by a participant regardless of time, place, or the number of times.
Embodiments of an information processing apparatus, an information processing method, and an information processing system will be described below with reference to the accompanying drawings.
In a first embodiment, one example of a mechanism that allows a terminal device of a participant to generate a modified image by adding an additional component to a material image that is displayable on an image display system, a configuration of an apparatus, and a method will be described. As one example, a case will be described in which a modified image (stamp) that is obtained by adding an additional component, such as a movement or decoration, to a picture (also referred to as a “drawn picture”) that a customer (hereinafter, referred to as an “event participant” or a “participant”) who has attended an event at a store or the like has generated on specified paper at the event site is provided to a terminal device of the participant.
Here, the “drawn picture” is a concept including a color-by-number. In the present embodiment, a “material drawn on a medium” includes not only an image drawn by an event participant, but also an image drawn by a staff person or the like. Further, a picture that is generated in advance, that is printed, or the like may be adopted, instead of the drawn picture. “Paper” is one example of a medium. The “medium” in the first embodiment is not limited to paper, but may be, for example, a medium on which a picture is drawn electronically or a medium on which a picture is drawn magnetically, as long as the medium can display a material.
The network 2 is a local area network (LAN), a virtual private network (VPN), the Internet, or the like. The network 2 also appropriately connects an application providing server, an external service providing server, a social networking service (SNS) server, and the like in a communicable manner, in addition to the above-described devices.
Each of the terminal device 20 and the content providing server 40 is configured with a computer. Each of the devices may be configured such that a part or whole of the device is operated by dedicated hardware.
At an event site, a staff person (operator) generates image data by reading, by a scanner 55, paper on which an image (for example, a color-by-number of a creature or the like) is drawn by a participant, and thereafter, by the image display system 50, adds a movement to the image of the picture and displays the image.
The image reading apparatus (scanner) 55 is one example of a “reading unit”. The image reading apparatus (scanner) 55 scans paper Y that is set at a predetermined position, and acquire an image (read image) of the paper Y. For example, the image reading apparatus 55 includes a scanner (imaging unit), a table on which the paper Y is placed, and a tool for fixing the scanner at a predetermined height with respect to the table. By setting the paper Y with the face up on the table and causing the scanner to optically scan a front surface of the paper Y, it is possible to read an image on the front surface of the paper Y.
The PC 51 controls entire operation of the image display system 50. The PC 51 acquires, as the read image, the paper Y on which a picture is drawn by an event participant at an event site from the image reading apparatus (scanner) 55, and registers the read image of the picture drawn on the paper Y in the DB 53.
The PC 51 extracts a material image, which serves as a material, from a predetermined region of the read image of the picture drawn by the participant, and registers the extracted material image in the DB 53. Further, the PC 51 analyzes the predetermined region of the read image of the picture drawn by the participant, and generates text data of an analysis result. The PC 51 registers the text data of the analysis result of the image in the DB 53. Further, the PC 51 transmits the material image and the text data, which are extracted from the read image of the picture drawn on the paper Y and which are registered in the DB 53, to the content providing server 40 at a predetermined timing.
Furthermore, the PC 51 sequentially generates display information A by adding a three-dimensional movement to the material image that is extracted from the read image of the picture drawn on the paper Y in the DB 53.
The PJ 52 projects the display information A to a projection medium 57 in accordance with a display signal output from the PC 51. The sensor 54 detects and outputs gestures, hand gestures, or the like of a person and the PC 51 updates a movement or the like of each of the pictures in accordance with output from the sensor 54. Meanwhile, the process performed by the PC 51 may be performed by a plurality of the PCs 51.
A handwriting region Y10 in which the event participant draws a picture in handwriting is arranged on the front surface Y1. In this example, a region Y11 for drawing a title of a picture in handwriting is also arranged. Furthermore, an identification region Y12 in which unique identification information is set is arranged on the front surface Y1. In
The identification information may be a two-dimensional code (for example, a quick response (QR) code (registered trademark)). Further, the identification information may be an identification code including numerals, alphabets, symbols, and the like. Furthermore, the identification information may be other markers. Moreover, the identification region Y12 may include a color code or the like. In this manner, the identification information may be appropriately set in the identification region Y12. In addition, marks or the like for specifying orientation of the paper and arrangement of each of the regions in accordance with the setting may be arranged.
Meanwhile, the example has been described above in which the event participant draws a picture freehand in the handwriting region Y10, but as illustrated in
A description region Y21 including descriptions of how to use a Web page to use the image drawn on the front surface Y1 is arranged in the back surface Y2. Further, an identification region Y22 in which the same identification information as the identification information set in the identification region Y12 on the front surface Y1 is arranged. In the identification region Y22, identification information including numerals, alphabets, symbols, and the like that can be read and input as keys to the terminal device 20 by a person is set.
Furthermore, an advertising region Y23 is arranged on the back surface Y2. In the advertising region Y23, an illustration of advertising of an event, text announcing the event, or the like can be set appropriately, for example.
Information in each of the regions in the paper Y can be set by performing printing, attaching a seal, or transcribing a URL that is arranged at an arbitrary location in the event site, or the like. In the following, explanation will be given on the assumption that each piece of information is printed.

System Operation
Various kinds of processing operation performed by the information processing system 1 will be described below.
Registration Process
First, an outline of a sequence for registering a material image or the like will be described below.
The sequence illustrated in
First, the image reading apparatus (scanner) 55 outputs, to the PC 51, a read image on the front surface Y1 of the paper Y set in the image reading apparatus (scanner) 55 (Step S1).
Subsequently, the PC 51 performs a material image generation process of generating the material image that is obtained by extracting the image in the handwriting region Y10 included in the read image (Step S2).
The PC 51 constructs management information on the material image from a predetermined store code and the identification information in the identification region Y12 in the read image, and requests the content providing server 40 to register the material image in a place indicated by the management information (Step S3).
The content providing server 40 registers the material image in a unique path indicated by the management information on the basis of a registration request issued by the PC 51 (Step S4).
Meanwhile, in the configuration illustrated in the first embodiment, the read image that is output to the PC 51 at Step S1 is displayed, as an image to which a movement is added, by the image display system 50 on an as needed basis.
Further, in the sequence, a procedure of causing the image reading apparatus (scanner) 55 to output the read image on the paper one by one to the PC 51, and causing the PC 51 to register the read image of the paper one by one every time the read image is received (Step S2 and Step S3) is repeatedly performed. However, a part or whole of the registration procedure may be performed collectively after a predetermined number of read images are accumulated or at predetermined time intervals.
Furthermore, in this example, as one example, the operator starts to read the image by pressing an image read start button every time the operator sets the single paper Y, on which the event participant has drawn the image, in the image reading apparatus (scanner) 55. However, if the image reading apparatus (scanner) 55 includes an auto document feeder (ADF), it may be possible to perform continuous reading of a plurality of pieces of the paper Y by pressing the image read start button once after setting the plurality of pieces of the paper Y.
Modified Image Generation Process
Next, a modified image generation process of generating a modified image by adding an additional component, such as a motion or decoration, to a material image by causing the terminal device 20 to access the content providing server 40 in the information processing system 1 will be described below.
First, if the terminal device 20 activates the Web browser in response to operation performed by a user, the content providing server 40 displays a top page P1 on the display 418 of the terminal device 20 (Step S11).
Here,
A participant selects a desired material image from the list of the thumbnails of the material images displayed on the top page P1 via the touch panel 421.
Meanwhile, the list of the material images displayed on the top page P1 may be sorted by stores or sorted by date at which events are held. Further, it may be possible to display, when a participant inputs identification information, only a material image associated with the identification information on the top page P1 that is displayed on the display 418 of the terminal device 20.
The acquiring unit 101 of the content providing server 40 acquires a desired material image that is selected by the terminal device 20 (Step S12).
Subsequently, the providing unit 102 of the content providing server 40 provides a modified image generation content (Web page), by which the additional component, such as a motion or decoration, can be added to the material image, to the terminal device 20 and displays the modified image generation content on the display 418 (Step S13).
Here,
A selected material image I1 is displayed in the modified image generation area A1. Further, a predetermined image (additional component) 12, such as a logo, an event name, or a hashtag, which is set in advance is displayed in the modified image generation area A1.
The participant adjusts a position of the material image I1 within a range of the modified image generation area A1 by using the position adjustment button B1 via the touch panel 421. Further, the participant adjusts a size of the material image I1 within the range of the modified image generation area A1 by using the size adjustment button B2 via the touch panel 421.
The additional component area A2 is an area for selecting various additional components. The additional components that are registered in advance are displayed in the additional component area A2. The additional components in this example may be pictures for decorating the material image or characters. Further, the “characters” include text data of the title of the picture that is written in handwriting in the region Y11.
The participant selects a desired additional component from among the additional components in the additional component area A2 via the touch panel 421.
The determining unit 103 of the content providing server 40 determines that a selected additional component 13 is to be synthesized in the modified image generation area A1 (Step S14). Meanwhile, the content providing server 40 may change a background of the modified image generation area A1 in accordance with the selected additional component (a picture or a character).
Further, the determining unit 103 of the content providing server 40 determines an additional component (movement) that is to be added to the material image I1 displayed in the modified image generation area A1 (Step S15). Meanwhile, the determining unit 103 of the content providing server 40 may also add a movement to the additional component (picture or character) 13 that is selected at Step S14. For example, the content providing server 40 randomly adds one of the following multiple movements that are stored.
1. jump
2. sway
3. rotate
4. run
Moreover, the determining unit 103 of the content providing server 40 may determine a to-be-added movement on the basis of feature data that is extracted from the material image I1 as described in Japanese Unexamined Patent Application Publication No. 2016-177595 as described above, for example. Furthermore, the determining unit 103 of the content providing server 40 may determine a motion for the material image I1 on the basis of the identification information for identifying the paper Y.
Here,
Thus, by using the modified image generation content (Web page) P2, the participant is able to move the material image I1 in the determined a movement or decorate a periphery of the material image I1 with the additional component (picture or character) 13.
If modification on the material image I1 is completed, the participant presses the generation button B3 via the touch panel 421. Meanwhile, if the participant re-does the modification on the material image I1, the participant presses the re-do button B4 via the touch panel 421. Further, if the participant does not know how to modify the material image I1, the participant presses the usage button B5 via the touch panel 421.
If the generation button B3 is pressed (Yes at Step S16), the generating unit 104 of the content providing server 40 generates a modified image (stamp) in which the additional component 13, such as a movement or decoration, is added to the material image I1 (Step S17).
Subsequently, the storage unit 105 of the content providing server 40 stores the modified image (stamp) in a storage destination, such as a camera roll, formed in the EEPROM 404 of the terminal device 20 (Step S18). The modified image is stored in the form of an animated GIF or a still image.
Here,
Meanwhile, the participant is able to accept selection of a social networking service (SNS), in which the modified image (stamp) S is to be shared, and upload the modified image (stamp) S by displaying a shared screen for the modified image (stamp) S that is stored in the camera roll formed in the EEPROM 404 of the terminal device 20.
As described above, according to the first embodiment, it is possible to generate a modified image in which the additional component, such as a movement or decoration, is added to the material image that is based on the picture drawn by the participant, so that even after the event, it is possible to provide an opportunity to have entertainment based on the picture drawn by the participant anytime, anywhere, and any number of times.
A second embodiment will be described below.
The second embodiment is different from the first embodiment in that a movement of a material image is set by using dedicated paper. In the description of the second embodiment below, explanation on the same components as those of the first embodiment will be omitted, and differences from the first embodiment will be described.
1. jump
2. sway
3. rotate
4. run
The PC 51 analyzes the movement selection region Y30 in the read image of the picture drawn by the participant, and generates movement data based on the analyzed movement. The PC 51 registers the movement data that is an image analysis result in the DB 53. Further, the PC 51 transmits the material image, the text data, and the movement data that are extracted from the read image of the picture drawn on the paper Y and registered in the DB 53 to the content providing server 40 at a predetermined timing.
Then, at Step S15 illustrated in
According to the second embodiment as described above, it is possible to cause the modified image (stamp), in which the additional component, such as a movement or decoration, is added to the material image, to move in the same manner as in the image display system 50 at the event site.
