Patent No. 6469875

In recent years, e-book works, i.e., content, have become more diverse. For example, there are webtoons that are read by scrolling vertically. Many webtoons are designed to be viewed on smartphones or tablet devices, and manga works generally have color pages, and some even include music and animation.

On the other hand, reading e-books on smartphones, tablet devices, etc. is a monotonous operation of scrolling to display and read the content one after the other. This is the same concept as turning the pages of a physical comic book or novel, because the purpose is to "enjoy the content" by turning the pages, and no other operations (movements) are required other than scrolling.

The object of the present invention is to provide a content providing system that allows users to enjoy content in electronic books by methods other than scrolling, which is normally done by scrolling.

(1) The content provision system of the present invention includes a content distribution device that distributes electronic books, and a user terminal that is provided with a viewer for viewing the electronic books and has a motion detection sensor.

The electronic book includes a plurality of still image cuts and at least one or more panoramic view cuts, and the viewer performs a first display control of reading the electronic book delivered and displaying the still image cuts in a predetermined display area in a direction in which the still image cuts are read in response to scrolling of the viewer, and a second display control of performing display processing of the panoramic view cut in response to a vertical or horizontal movement of the user terminal detected by a motion detection sensor. Here, the electronic book can be configured such that pre-reading information of the panoramic view cut is set in the predetermined still image cut. The viewer reads the electronic book delivered by streaming from the content delivery device and displays it in the predetermined display area, and determines whether or not there is pre-reading information in the still image cut reading process, and transmits a delivery request of the panoramic view cut to the content delivery device when it is determined that there is pre-reading information. The content delivery device can be configured to accept the delivery request of the panoramic view cut and transmit it to the user terminal, and the viewer can be configured to execute reading processing of the received panoramic view cut at a timing before the panoramic view cut is displayed in the display area, and perform display processing of the panoramic view cut that has been pre-read in the second display control.

(2) In (1) above, the panoramic view cut can be configured to include a first area displayed in response to scrolling on the viewer, and a second area depicting a wide-angle area in the up-down or left-right direction from a viewpoint centered on the first area. In the second display control, the viewer can acquire the up-down or left-right movement of the user terminal detected by a motion detection sensor, and display the second area located in the direction of the acquired movement of the user terminal.

(3) In (2) above, the viewer can be configured to perform the second display control when the first area is displayed at a predetermined percentage or more of the display area, when the first area is scrolled to a predetermined display position within the display area, or when the first area is selected by a user operation.

( 4 ) In the above (1) to ( 3 ), the electronic book may be composed of vertically long content in which still image cuts and panoramic view cuts are arranged in order in the reading direction in response to vertical scrolling of the viewer.

( 5 ) The program of the present invention is executed on a user terminal equipped with a motion detection sensor to read an electronic book distributed from a content distribution device. The electronic book includes a plurality of still image cuts and at least one or more panoramic view cuts, and the user terminal is made to realize a first function of reading the distributed electronic book and displaying the still image cuts in a predetermined display area in a reading forward direction corresponding to scrolling of the display area , a second function of acquiring a vertical or horizontal movement of the user terminal detected by the motion detection sensor, and a third function of performing a display process of the panoramic view cut corresponding to the vertical or horizontal movement of the user terminal. Here, the electronic book can be configured such that pre-read information of the panoramic view cut is set to the predetermined still image cut. The above program further realizes a fourth function of reading an electronic book streamed from a content distribution device and displaying it in the display area, as well as determining whether or not there is pre-loaded information in the still image cut reading process, and sending a distribution request for a panoramic view cut to the content distribution device if it is determined that there is pre-loaded information, and a fifth function of receiving a panoramic view cut based on the distribution request distributed from the content distribution device, and executing reading processing of the received panoramic view cut at a timing before the panoramic view cut is displayed in the display area, and the above third function can be configured to perform display processing of the panoramic view cut that has been pre-loaded in response to vertical or horizontal movement of the user terminal.

In addition to displaying still image cuts in the reading direction in response to scrolling on the viewer, the present invention also processes the display of panoramic view cuts in response to vertical or horizontal movement of the user terminal detected by a motion detection sensor, making it possible to display content using methods other than scrolling and providing a presentation for enjoying the content.

First Embodiment
1 to 6 are diagrams for explaining a content providing system according to a first embodiment, and FIG. 1 is an explanatory diagram of a network configuration and functional blocks.

The content providing system of this embodiment provides an electronic book service that allows users to view electronic books on a user terminal 100. As described above, electronic books are electronic data of books such as books, manga, and pocket books, and are content that can be read page by page or cut by cut.

In the following explanation, Webtoon works are used as an example of an e-book, but the present invention can be applied to browsing not only Webtoons but also various other content provided as e-books. In addition to manga, the present invention can also include e-books in which panoramic view cuts are applied to illustrations or titles of novels, and can be applied to e-books in general.

The user terminal 100 is, for example, a portable mobile terminal such as a multi-function mobile phone like a smartphone or a tablet terminal, and is equipped with wireless communication capabilities. The communication unit 110 controls communication in mobile communication networks such as IP networks and 4G/5G/LTE lines (mobile data communication via mobile phone lines). For example, it is equipped with a Wi-Fi (wireless LAN) function and a mobile data communication function using a SIM card. Note that it may or may not have a calling function. In addition, the user terminal 100 is equipped with a speaker 130 as an audio output device, a touch panel type display input unit 140, a motion detection sensor 150, and a memory unit 160.

The control unit 120 of the user terminal 100 is equipped with a display control unit 121. This display control unit 121 is an electronic book viewing application that includes a viewer 121a for viewing electronic books. The viewer 121a reads electronic book data that is streamed from the content distribution device 300, and performs display and playback processing. Details of the display and playback control of the viewer 121a will be described later.

In addition to being provided as an e-book viewing application including the viewer 121a, the viewer 121a can also be provided, for example, as a plug-in application that extends the functionality of a browser. In this case, the browser is the display control unit 121, and when an operation to view an e-book is performed in the display control of the browser, the viewer 121a, which is a plug-in application, is executed and the e-book is displayed and played.

The display control unit 121 including the viewer 121a may be pre-installed in the user terminal 100, or may be downloaded and installed from a specified application distribution server at any time when the user views an e-book. Also, when operating as a plug-in, the viewer 121a may be downloaded or installed at the timing of the browser's display control.

The motion detection sensor 150 is a sensor device that detects the motion of the user terminal 100, i.e., the direction in which the user terminal 100 moves (up, down, left, right) while being held in the hand. The motion detection sensor 150 can be a sensor device such as a known acceleration sensor (motion sensor) or gyro sensor, or it may be a sensor device that combines an acceleration sensor and a gyro sensor.

The content distribution device 300 delivers the corresponding electronic book data in a streaming manner in response to a delivery request from the user terminal 100. The communication device 310 controls the communication for streaming delivery via an IP network or a mobile communication network. The control device 320 includes a content registration unit 321 and a content distribution unit 322. The storage device 330 stores various information including the electronic book data.

The content registration unit 321 accepts registration of electronic book data to be distributed and stores it in the storage device 330. The content registration unit 321 also generates and provides a screen on the user terminal 100 on which each registered electronic book can be viewed (selected). In other words, the registered electronic books are made selectable by the user and made available for streaming distribution.

The content delivery unit 322 delivers electronic book data in a streaming manner. Streaming delivery means that electronic book data is divided into a predetermined number of packets and delivered, and the viewer 121a of the user terminal 100 reads the data in packets and displays and plays the data. The viewer 121a discards the packets (data) each time display or playback is completed, and controls the data so that they are not left in the memory area of the user terminal 100.

An example of a packet unit is, for example, a unit of multiple cuts that make up the electronic book data. The content distribution unit 322 can transmit data sequentially for each of the multiple cuts that make up the electronic book data. Note that the packet unit can be set arbitrarily. For example, packets can be divided by page unit of a manga or novel.

In this embodiment, the electronic book data is described as being composed of multiple cuts as an example, but the size of the cuts is arbitrary. For example, the viewer 121a of the user terminal 100 has a predetermined display area (display range), and one cut may be approximately the same size as the display area, or may be any size that allows multiple cuts to be displayed within the display area, or may be a cut larger than the display area. Also, in manga, the word "frame" is sometimes used to correspond to a cut. In this case, it is possible to include a case where one cut is composed of one frame, or one cut is composed of multiple frames.

In addition, in streaming distribution, in addition to the case where one cut is one packet, one cut can be divided into multiple packets for distribution, or one packet can contain multiple cuts for distribution, and it is not necessary to be limited to the case where one cut is one packet.

Figure 2 is a diagram showing an example of e-book data in this embodiment. As shown in Figure 2, the e-book data is made up of multiple cuts C1 to Cn, which are arranged in the direction in which the work is read. In other words, cut C1 is at the beginning, and the individual cuts are arranged in order according to the flow of the work. The user can scroll the display area of the viewer 121a to sequentially view the cuts arranged in the direction in which the work is read.

The electronic book data is composed of still image cuts and panoramic view cuts. The still image cuts are image data. The panoramic view cuts are also image data, but as shown in FIG. 2, they are composed of still image cut C3 that is displayed in response to scrolling on viewer 121a, and still image cuts C31, C32 (right side) and still image cuts C33, C34 (left side) that depict wide-angle areas in the left and right directions from a viewpoint centered on still image cut C3 (first area).

In other words, the panoramic view cut in this embodiment is a still image cut that is long horizontally in the left-right direction, and may be a single continuous still image cut or a cut in which multiple still image cuts are connected horizontally. The panoramic view cut includes still image cut C3 as a first area that is displayed in response to scrolling on viewer 121a, and still image cuts C31 and C32 (right side) and still image cuts C33 and C34 (left side) are included as second areas that depict wide-angle areas in the left-right direction from a viewpoint centered on this first area.

The panoramic view cut shown in FIG. 2 is an example, and may be, for example, a panoramic view cut including only a still image cut C31 on the right side of the still image cut C3, or a panoramic view cut including only a still image cut C33 on the left side of the still image cut C3. The number of cuts included in the second area is arbitrary.

Figures 3 and 4 are diagrams for explaining display control in the user terminal 100. Figure 4 is a top view of Figure 3. When the user moves the user terminal 100 left or right, the motion detection sensor 150 detects the direction of movement of the user terminal 100. The viewer 121a works in conjunction with the motion detection sensor 150 to obtain the direction of movement of the user terminal 100 detected by the motion detection sensor 150. The viewer 121a displays a still image cut of the second area located in the direction of the detected movement of the user terminal 100.

To explain the case of the panoramic view cut illustrated in FIG. 2, when the viewer 121a detects that the user terminal 100 has moved to the right while the still image cut C3 is being displayed, the viewer 121a can display the still image cut C31 as described above, and when the viewer 121a detects that the user terminal 100 has further moved to the right while the still image cut C31 is being displayed, the viewer 121a can display the still image cut C32.

Figure 5 is a diagram showing a modified example of electronic book data of this embodiment. The example in Figure 5 is a panoramic view cut that includes still image cuts C35 (upper side) and 36 (lower side) that depict a wide-angle area in the vertical direction from a viewpoint centered on still image cut C3 (first region) in addition to the left and right direction. The second region also includes still image cuts C33a and 33b that depict a wide-angle area in the vertical direction from a viewpoint centered on still image cut C33. As with the horizontally elongated panoramic view cut described above, the cut depicting a wide-angle area in the vertical direction can be composed of a single continuous still image cut, or a cut in which multiple still image cuts are connected vertically.

In this way, the panoramic view cut of this embodiment can be configured to include only the left-right direction, only the up-down direction, both the left-right and up-down directions, or only one of the up-down, left-right directions.

Figure 6 shows the processing flow of the content provision system of this embodiment.

The content distribution device 300 performs a registration process for electronic book data for streaming distribution (S301).

If the user terminal 100 does not have a viewer 121a installed for viewing electronic books, the user terminal 100 downloads and installs an electronic book viewing application including the viewer 121a (S101). The electronic book viewing application can be downloaded from a specific application download site.

When the e-book viewing application is selected by the user operation, the user terminal 100 connects to the content distribution device 300. The content distribution device 300 provides the user terminal 100 with a selection screen for registered e-books, i.e., a selection screen for viewable e-books (S302). The user selects the e-book they wish to view on the selection screen provided by the content distribution device 300 (S102). The display control unit 120 (e-book viewing application) of the user terminal 100 transmits a streaming distribution request for the selected e-book, and starts the viewer 121a in response to the selection of the e-book (S103). In addition, upon startup, the viewer 121a performs a linking process so that it can obtain motion detection information for the user terminal 100 from the motion detection sensor 150 (S104).

The content distribution device 300 (content distribution unit 322) starts streaming distribution of the selected electronic book (S303). The viewer 121a of the user terminal 100 reads each packet in the order in which it was received, and performs display and playback processing of the cuts that have been read in the display area of the viewer 121a (S105).

The viewer 121a performs a first display control to read the delivered electronic book and display still image cuts in a predetermined display area in a reading forward direction in response to scrolling of the viewer 121a, and a second display control to display panoramic view cuts in response to vertical or horizontal movement of the user terminal 100 detected by the motion detection sensor 150.

Specifically, it is determined whether or not the cuts displayed in the display area include a panoramic view cut (S106). If it is determined that a panoramic view cut is included (YES in S106), the vertical or horizontal movement of the user terminal 100 detected by the motion detection sensor 150 is acquired (S107), and still image cuts constituting the panoramic view cut located in the direction of the acquired movement of the user terminal 100 are displayed (S108). In other words, the viewer 121a performs terminal motion-linked display control (second display control) in response to the movement of the user terminal 100, rather than a scroll operation on the viewer 121a.

At this time, the viewer 121a can be configured to perform the above-mentioned second display control when the still image cut C3 (first area) constituting the panoramic view cut is displayed at a predetermined rate or more in the display area, when the still image cut C3 is scrolled to a predetermined display position in the display area, or when the still image cut C3 is selected (tapped) by a user operation.

Furthermore, when still image cut C3 is displayed in the display area by vertical scrolling, the panoramic view cut can be provided with a mechanism for making the continuity with still image cuts located to the left and right clear, so that the presence of cuts continuing to the left and right can be easily grasped. For example, the still image cut C3 can be configured so that parts of speech bubbles, people, landscapes, objects, etc. drawn in still image cuts located to the left and right are displayed in the still image cut C3. It is also possible to clearly indicate that it is a panoramic view cut by displaying a mark, icon, message, etc.

The viewer 121a can determine whether or not a cut displayed in the display area is a panoramic view cut by, for example, adding identification information (such as a flag or an identifier) indicating that the cut is a panoramic view cut.

Then, as the cuts move within the display area in response to the scroll operation, a streaming delivery request for the next cut to be read is transmitted (S109), and the content delivery device 300 performs streaming delivery based on the delivery request in response to the scroll operation (S304). The user terminal 100 returns to step S105 to read packets received in sequence and perform display and playback processing until viewing is completed (NO in S110). When viewing is completed (when an operation to close the viewer 121a is performed) (YES in S110), the viewer 121a is closed (S111).

The content providing system of this embodiment provides an electronic book including a panoramic view cut, and the panoramic view cut is configured to include an area displayed in response to scrolling on the viewer 121a of the user terminal 100, and an area depicting a wide-angle area in the vertical or horizontal direction from a viewpoint centered on the area. The viewer 121a is equipped with a display control that displays still image cuts within the display area in response to a scroll operation by the user, as well as a terminal motion-linked display control (second display control) that acquires the vertical or horizontal movement of the user terminal 100 detected by the motion detection sensor 150, and displays cuts located in the direction of the acquired movement of the user terminal 100.

This allows content to be displayed using methods other than scrolling, providing a way to enjoy the content.

Second Embodiment
7 and 8 are diagrams showing the second embodiment, and FIG. 7 is a diagram showing an example of electronic book data of the present embodiment.

In this embodiment, a pre-loading function has been added to the above-mentioned first embodiment. A panoramic view cut is composed of multiple still image cuts, and therefore has a larger data capacity than other still image cuts. For this reason, when the viewer 121a operates to sequentially display panoramic view cuts sent by streaming distribution in real time, it takes a long time to load the data due to its large volume, and the display of the panoramic view cuts may not be able to keep up, resulting in a delay in the display process of the panoramic view cuts, or the cuts may not be displayed at the appropriate time and may get stuck midway.

Therefore, in this embodiment, in a content providing service that provides electronic book data by streaming distribution, it is possible to smoothly display electronic book data including panoramic view cuts on a user terminal 100.

Specifically, as shown in FIG. 7, when a panoramic view cut is included in electronic book data, a mechanism is introduced in which the timing of delivery of the panoramic view cut is performed before the panoramic view cut is displayed in the viewer 121a. In the example of FIG. 7, "pre-load information" is set for a still image cut C3 that precedes a panoramic view cut C9 in the cut order according to the vertical scroll direction.

The function of setting "pre-loading information" for electronic book data can be provided by the content registration unit 321. For example, the content registration unit 321 can be configured to control the selection of any cut of the registered electronic book data via a specified screen and set the pre-loading information. At this time, in addition to setting the pre-loading information, the pre-loading information can be configured to be linked (associated) with the panoramic view cut to be distributed.

The pre-read information is information for the viewer 121a to make a distribution request of a panoramic view cut to the content distribution device 300, and is read in a read process when the viewer 121a performs a display process. The pre-read information is a trigger for making a distribution request, and when only one panoramic view cut is included in electronic book data, the pre-read information may be a simple trigger. However, when one electronic book includes multiple panoramic view cuts, the pre-read information is configured to identify which panoramic view cut to request for distribution, in other words, which panoramic view cut the content distribution device 300 should distribute. For example, the pre-read information may be configured to include cut identification information of the panoramic view cut to be requested for distribution, and the cut identification information may be included in the distribution request to be sent to the content distribution device 300. In another method, the content distribution device 300 may hold identification information of the cut for which the pre-read information is set, and the viewer 121a may include identification information of the cut read when sending a distribution request.

The viewer 121a reads each packet of the streaming electronic book data and displays them in the display area in the order in which they are read. The user can read each cut by scrolling vertically. In the case of Webtoons, electronic book data that supports vertical scrolling is created, and cuts are arranged vertically as you read.

The viewer 121a works in conjunction with the scroll control of the display area by the touch panel display/input unit 140, and requests the content distribution device 300 to distribute the next cut (a cut that has not yet been distributed) corresponding to the cut currently displayed in the display area according to the detected amount of upward or downward scrolling. The streaming distribution control can, for example, distribute up to several cuts ahead of the cut displayed in the display area.

The viewer 121a reads and displays each cut, and at this time, checks whether or not pre-read information exists for each read cut. If the viewer 121a determines that pre-read information exists, the viewer 121a transmits a distribution request for the subsequent panorama view cut C9 to the content distribution device 300. In other words, in a work in which multiple cuts are arranged, the viewer 121a performs control so that the subsequent panorama view cut that is not being streamed can be received in advance of the currently displayed cut, and the viewer 121a completes the reading process when the display process of the panorama view cut is performed.

In this way, in an electronic book in which still image cuts and panoramic view cuts are arranged in order in the reading direction in response to scrolling on the viewer 121a, the pre-loading information is set to a still image cut that is a predetermined number of cuts before the panoramic view cut in the reading direction, and a pre-delivery request and pre-loading process are performed on the panoramic view cut based on the pre-loading information.

Note that the number of still image cuts before the panoramic view cut for which pre-loading information is set is arbitrary, but the pre-loading information can be set at an interval corresponding to at least a cut for which the panoramic view cut is not automatically streamed from the content distribution device 300 when the still image cut for which pre-loading information is set is displayed in the display area (when it is determined whether pre-loading information is present). In streaming distribution, display processing is performed in order from the received packets, so the content distribution device 300 can deliver each packet several cuts ahead of the cut currently displayed in the display area. This allows smooth display processing in the reading forward direction.

On the other hand, when a still image cut for which pre-load information is set is loaded and displayed, if the panoramic view cut is located at an interval at which a panoramic view cut is already automatically distributed from the content distribution device 300, it is possible to control not to perform a distribution request based on the pre-load information of the viewer 121a and distribution based on the pre-load information of the content distribution device 300. In other words, it is possible to configure so that pre-load information is set for a still image cut that is spaced at an interval at which a panoramic view cut is not automatically distributed from the content distribution device 300 when a still image cut for which pre-load information is set is loaded and displayed.

The viewer 121a may make a delivery request based on the pre-loaded information when the still image cut for which pre-loaded information is set is displayed at a predetermined ratio or more in the display area of the viewer 121a. For example, the delivery request may be made when 1/3 or more of the cut is displayed in the display area. As another timing, the delivery request for the panoramic view cut may be sent to the content delivery device 300 when the still image cut for which pre-loaded information is set is scrolled to a predetermined display position in the display area. In this case, the delivery request may be made when the top end of the cut C3 for which pre-loaded information is set is moved to the top end of the display area by scrolling, or when the cut C3 is displayed in the center area of the display area.

Figure 8 is a diagram showing the processing flow of the content providing method and viewer of this embodiment. Note that in Figure 8, steps S1001, S1002, S1003, and steps S3001, S3002 are processes added to the processing flow shown in Figure 6 of the first embodiment, and the same processes as in the first embodiment are given the same reference numerals and will not be described.

The content distribution device 300 performs a process of setting pre-read information for electronic book data that includes panoramic view cuts registered as targets for distribution (S3001).

The content distribution device 300 (content distribution unit 322) starts streaming distribution of the selected electronic book (S303). The viewer 121a of the user terminal 100 reads each packet in the order in which they were received, and performs display processing of the cuts that have been read in the display area of the viewer 121a (S105).

The viewer 121a judges whether pre-read information is set in the process of reading and displaying a cut to be displayed in the display area (S1001). If it is determined that pre-read information is not set, a streaming distribution request for the next cut to be read is transmitted (S109), and the content distribution device 300 performs streaming distribution based on the distribution request according to the scrolling operation (S304). The user terminal 100 returns to step S105 to read packets received in sequence and perform display and playback processing until viewing is completed (NO in S110). When viewing is completed (when an operation to close the viewer 121a is performed) (YES in S110), the viewer 121a is closed (S111).

On the other hand, if it is determined in step S1001 that the pre-loaded information is set (YES in S1001), the content distribution device 300 transmits a distribution request for the panoramic view cut set in the pre-loaded information (S1002). When the content distribution device 300 receives the distribution request based on the pre-loaded information, the content distribution device 300 pre-distributes the corresponding panoramic view cut (S3002). The user terminal 100 performs a pre-loading process for the received panoramic view cut (S1003).

In this embodiment, when streaming electronic book data is viewed on a user terminal 100 such as a smartphone, if the data contains a panoramic view cut with a large data capacity, pre-loading information is set, and the panoramic view cut can be displayed and played back smoothly. This allows the display process of the panoramic view cut to be performed at a timing optimized for the purpose of the presentation.

This embodiment has been described above, but scrolling of the display area of the viewer 121a may be performed by an automatic scrolling function of the viewer 121a in addition to a user operation.

Although a streaming distribution method has been described as an example of a content providing system, this content providing system can also be applied to a form in which electronic books are provided by a download method.

In addition, each function of the user terminal 100 and the content distribution device can be realized by a program, and computer programs prepared in advance to realize each function are stored in an auxiliary storage device, and a control unit such as a CPU reads the program stored in the auxiliary storage device into a main storage device, and the control unit executes the corresponding program read into the main storage device, thereby operating the function of each unit.

The above program can also be provided to a computer in a state in which it is recorded on a computer-readable recording medium. Examples of computer-readable recording media include optical disks such as CD-ROMs, phase-change optical disks such as DVD-ROMs, magneto-optical disks such as MO (Magnet Optical) and MD (Mini Disk), magnetic disks such as floppy (registered trademark) disks and removable hard disks, and memory cards such as Compact Flash (registered trademark), Smart Media, SD memory cards, and memory sticks. Also included as recording media are hardware devices such as integrated circuits (IC chips, etc.) that are specially designed and configured for the purposes of the present invention.
