[1-4. Manga display function on mobile terminal]
The mobile terminal 3 displays the manga distributed from the server 4 on the screen 3a using a function of the manga viewing application (hereinafter referred to as "manga display function"), thereby allowing the user to view the manga. Note that the manga display function according to the present embodiment scrolls the manga displayed on the screen 3a only in one of the vertical direction and the horizontal direction (the long axis direction or the short axis direction of the screen 3a) of the screen 3a. That is, the manga scrolls in one direction based on the screen 3a.

[1-4-1. Screen rotation operation]
The manga display function according to the present embodiment performs rotation notification at a predetermined notification timing according to the progress of the manga to urge the user to perform horizontal rotation at a predetermined angle using the screen 3a as a reference plane. When the rotation notification is performed, the user performs a screen rotation operation to horizontally rotate the screen 3a while reading the manga on the mobile terminal 3. Note that, in the mobile terminal 3 according to the present embodiment, since the screen 3a is integrally and inseparably provided in the main body of the mobile terminal 3, the rotation of the screen 3a and the rotation of the mobile terminal 3 in the following description are synonymous.

As a result, even if the scrolling direction of the manga displayed on the screen 3a is one direction, the manga display function allows the user to horizontally rotate the screen 3a to change the scrolling direction of the manga up, down, left, right, or diagonally based on the user's viewpoint. It becomes possible to change the direction in various directions. That is, the manga displayed on the screen 3a is scrolled in a pseudo manner, such as vertically or horizontally. Therefore, the manga display function enables more diverse expressions for the manga displayed on the screen 3a, such as making the manga displayed on the screen 3a feel like a moving image.

The screen rotation operation according to this embodiment will be described in detail with reference to FIGS. 4 and 5.

FIG. 4 is a schematic diagram showing an example of manga data 50 representing a manga displayed on the screen 3a. The manga data 50 is created on the assumption that the manga will be scrolled in only one direction and that a screen rotation operation will be performed. The example in FIG. 4 shows a form in which the manga is scrolled in the vertical direction (long axis direction) of the screen 3a. Note that the manga data 50 is composed of a plurality of still images 52. Although the size of the still image 52 is fixed in the horizontal direction (corresponding to the short axis direction of the screen 3a), the length in the vertical direction (corresponding to the long axis direction of the screen 3a) is determined by the manga artist. Can be determined arbitrarily.

FIG. 5 shows an image displayed on the screen 3a from the user's viewpoint when the user performs a screen rotation operation. Note that the arrow S in FIG. 5 is the scroll direction of the manga displayed on the screen 3a. Further, the manga display function according to the present embodiment turns off a function that automatically rotates the image displayed on the screen 3a in accordance with the horizontal rotation of the screen 3a (so-called automatic rotation function of the screen 3a).

FIG. 5A shows a state in which the mobile terminal 3 is held by the user with the upper end 3t facing upward from the user's viewpoint, and in the following description, this state will be referred to as a normal holding state. In the normal hold state, the manga scrolls from top to bottom from the user's perspective. FIG. 5(B) shows a state in which the mobile terminal 3 is rotated to the right by 90 degrees from the normal holding state, and the upper end 3t of the mobile terminal 3 is located on the right side of the user's viewpoint. It is called a state. In the right rotation hold state, the manga scrolls from right to left from the user's viewpoint. FIG. 5C shows a state in which the mobile terminal 3 is rotated 90 degrees to the right from the right rotation holding state (rotated 180 degrees from the normal holding state), and the upper end 3t of the mobile terminal 3 is located on the lower side from the user's viewpoint. In the following explanation, this state will be referred to as a reverse hold state. In the reverse hold state, the manga scrolls from bottom to top from the user's perspective.

That is, the still image 52A in FIG. 4 is created on the assumption that the mobile terminal 3 is held by the user in the normal holding state and the manga is viewed, as shown in FIG. 5(A). Furthermore, the still image 52B in FIG. 4 is created on the assumption that the mobile terminal 3 is held by the user in a clockwise rotation holding state and the manga is viewed, as shown in FIG. 5(B). Furthermore, the still image 52C in FIG. 4 is created on the assumption that the mobile terminal 3 is held by the user in an inverted holding state and the manga is viewed, as shown in FIG. 5(C). That is, the still images 52 constituting the manga data 50 are arranged in an orientation corresponding to the rotation of the screen 3a (mobile terminal 3) on the premise that the user performs a screen rotation operation.

Note that the rotation angle for rotating the mobile terminal 3 shown in FIG. 5 is an example. For example, an image may be displayed on the screen 3a that is created assuming that the user rotates the mobile terminal 3 from the normal holding state by 45 degrees and holds it diagonally, and scrolls diagonally.

[1-4-2. Rotation notification]
The manga display function performs rotation notification at a predetermined notification timing to urge the user to rotate the screen 3a. As an example, the manga display function according to the present embodiment displays a rotation notification image 54 on the screen 3a together with the manga to prompt the user to rotate the screen 3a, as shown in FIGS. 5 and 6, as a rotation notification. When the rotation notification image 54 is displayed on the screen 3a, the user rotates the mobile terminal 3 according to the display of the rotation notification image 54 and continues viewing the manga. The rotation angle is expressed by, for example, a combination of a range from 0 to 180 degrees and a rotation direction.

As shown in FIG. 6(A), the rotation notification image 54 according to the present embodiment is composed of an arrow image 54A indicating the rotation direction of the screen 3a (mobile terminal 3) and a numeric image 54B indicating the rotation angle. It is displayed superimposed on the manga at one of the four corners of the screen 3a. Further, the display position of the rotation notification image 54 according to the present embodiment is the upper end of the screen 3a in the scrolling direction of the manga. Since the user's line of sight is directed in the scroll direction of the manga, by displaying the rotation notification image 54 at the upper end of the scroll direction side of the manga, the user can naturally recognize the rotation notification image 54 without feeling uncomfortable.

Note that the configuration and display position of the rotation notification image 54 are not limited to this, and other configurations and display positions may be used as long as the user can recognize the rotation notification. For example, as shown in FIG. 6(B), the rotation notification image 54 may be composed of a terminal schematic image 54C showing the mobile terminal 3 and an arrow image 54A. The terminal schematic image 54C is displayed so that the user can recognize the rotational state that the user should maintain. Furthermore, the rotation notification image 54 may be displayed in an highlighted manner, such as by blinking, in order to be easily recognized by the user.

Here, the manga data 50 is added with rotation information indicating the rotation timing for rotating the screen 3a and the rotation angle of the screen 3a. Then, the manga display function performs rotation notification based on the rotation information added to the manga (manga data 50) distributed from the server 4. Thereby, the manga display function can prompt the user to rotate the screen 3a through simple processing. Note that the rotation timing and rotation angle of the screen 3a are determined according to the intention of the manga artist.

Rotation information will be explained with reference to FIG. 4. Arrows A1 and A2 shown in FIG. 4 indicate rotation timing. The rotation timing is, for example, between the still image 52A and the still image 52B, or between the still image 52B and the still image 52C, but is not limited to this, and the rotation timing may be in the middle of one still image 52. Good too. Note that the rotation timing is expressed, for example, by coordinates based on the beginning of the manga data 50.

The notification timing according to this embodiment is the same as the rotation timing when the user rotates the screen 3a, but is not limited to this. The notification timing may be a timing before the rotation timing, for example, the notification timing may be a predetermined number of pages or a predetermined number of frames before the rotation timing.

If the notification timing is set before the rotation timing, the manga display function will display a countdown until the rotation timing is reached, so that the user can clearly recognize the rotation timing, and then display a countdown after the rotation timing is reached. The rotation notification image 54 is highlighted until the screen 3a is rotated. The countdown display displays, for example, the number of pages or frames remaining until the rotation timing is reached. The highlighted display of the rotation notification image 54 is, for example, a change in the color of the rotation notification image 54, an enlargement of the rotation notification image 54, a blinking of the rotation notification image 54, or the like.

Note that when the user rotates the screen 3a at a rotation angle larger than the rotation angle notified by the rotation notification image 54, the rotation state of the screen 3a is adjusted to be an appropriate rotation state for the scrolling direction of the manga. The rotation notification image 54 may be updated and displayed.

In addition, when the manga displayed on the screen 3a reaches the rotation timing, the manga display function does not display the still image 52 (manga scene) after the rotation timing on the screen 3a until the rotation of the screen 3a is detected. A process (hereinafter referred to as "rotation detection process") may be performed.

In other words, the manga display function transitions the manga scene displayed on the screen 3a to the next scene only when the rotation of the screen 3a is detected after the manga reaches the rotation timing, while detecting the rotation of the screen 3a. If not, the next scene will not be displayed. That is, since the next scene is a still image 52 created in accordance with the rotation of the screen 3a, by performing rotation detection processing, the user can read the manga at an appropriate rotation angle of the screen 3a according to the manga scene. You will be viewing it.

Note that the rotation detection process may transition the manga scene displayed on the screen 3a to the next scene when the detected actual rotation angle of the screen 3a matches the rotation angle indicated by the rotation information, or When rotation of the screen 3a is detected, the manga scene displayed on the screen 3a may be transitioned to the next scene regardless of the detected rotation angle.

[1-4-3. Scroll operation]
The manga display function scrolls the manga in accordance with the user's operation using the indicator on the screen 3a. Note that the indicator according to this embodiment is a user's finger, for example.

When scrolling the manga displayed on the screen 3a, the user moves (swipes or flicks) his or her finger touching the screen 3a in the scrolling direction, for example. As described above, the scrolling direction according to the present embodiment is from the upper end 3t to the lower end 3u with respect to the mobile terminal 3, but is not limited thereto, and may be from right to left. The manga display function scrolls the manga when the screen 3a (touch panel display 3a) detects a swipe or flick (hereinafter referred to as "scroll operation") while the manga is being displayed on the screen 3a.

Further, the manga display function changes the scrolling speed of the manga depending on the moving speed of the user's finger performing the scrolling operation. That is, the faster the moving speed of the finger, the greater the amount of scrolling of the still image 52 of the manga.

The manga display function according to the present embodiment performs scroll stop control to stop scrolling of the manga when the manga displayed on the screen 3a reaches the rotation timing. That is, the manga display function according to the present embodiment does not scroll the manga any further unless the manga is rotated at the rotation timing. Therefore, the user can view the manga in a scrolling state that meets the intention of the manga author.

Furthermore, the user may perform a scroll operation in the opposite direction (hereinafter referred to as "reverse scroll operation") in order to return to the progress of the manga. When a reverse scroll operation is performed and the manga displayed on the screen 3a reaches the rotation notification timing, the rotation notification image 54 is placed in a position different from that of a normal scroll operation (hereinafter referred to as "forward scroll operation"). may be displayed.

For example, as shown in FIG. 5B, when the rotation notification image 54 is displayed at the top left of the screen 3a in a forward scroll operation, the rotation notification image 54 is displayed at the top right of the screen 3a in a reverse scroll operation. That is, when a reverse scroll operation is being performed, the rotation notification image 54 is displayed in a horizontally opposite position compared to when a forward scroll operation is being performed. The manga data 50 has rotation information indicating the rotation timing and rotation angle corresponding to a reverse scroll operation, and the manga display function provides rotation notification based on the rotation information when a reverse scroll operation is performed. The image 54 may be displayed on the screen 3a.

[1-4-4. Inertial scroll]
The manga display function according to the present embodiment changes the amount of scrolling of the still image 52 forming the manga according to the inertial force based on the moving speed of the finger of the user performing the scroll operation. Specifically, the faster the user's finger moves, the more the manga continues to scroll even if the user's finger moves away from the screen 3a. Note that the inertial force referred to here is a pseudo inertial force that is predetermined according to the moving speed of the user's finger, and this inertial force decreases with the passage of time, that is, the amount of scrolling after the finger is removed from the screen 3a. Become. Further, in the following description, scrolling due to inertial force will be referred to as inertial scrolling.

Here, the manga display function may perform scroll continuation control to continue scrolling the manga according to the inertial force even if the manga displayed on the screen 3a reaches the rotation timing. That is, the scroll continuation control does not cause the manga to be scrolled any further unless the screen 3a is rotated at the rotation timing, but continues scrolling even when the rotation timing is reached when inertial force is generated. Therefore, scroll continuation control enables smooth scrolling according to the user's scrolling operation.

Note that if the user is unable to rotate the screen 3a in accordance with the rotation timing, the user may feel uncomfortable because the scrolling direction that he or she recognizes is different from the scrolling direction of the manga. For this reason, if the manga display function continues scrolling by scroll continuation control without rotating the screen 3a even after the rotation timing has been reached, the manga display function may cause the rotation notification image 54 to blink or display it in an enlarged manner. Emphasis is displayed to urge the user to rotate the screen 3a more strongly.

Whether to use the scroll stop control or the scroll continuation control may be determined by the user's settings, for example, or may be set in advance according to the wishes of the manga artist. Further, in one manga, scroll stop control and scroll continuation control may coexist. For example, if the still image 52C includes a conversation important to the story of the manga, scroll stop control is performed to stop scrolling. On the other hand, in scenes where it is desired to express a sense of speed in the manga, scroll continuation control is performed, allowing the manga to proceed without stopping scrolling.

[1-4-5. Conditional scroll]
The manga display function according to the present embodiment determines at a predetermined timing (hereinafter referred to as "condition detection timing") whether or not a predetermined condition for scrolling the manga (hereinafter referred to as "scroll condition") is satisfied. , the manga may be scrolled (progressed) when scrolling conditions are met. Note that the manga display function does not scroll the manga if the scroll condition is not satisfied at the condition detection timing.

The manga display function causes the manga to be scrolled, for example, when an instruction is issued to the user from the mobile terminal 3 as a scroll condition and an input is made to the mobile terminal 3 in accordance with the instruction. Note that instructions to the user from the mobile terminal 3 are displayed on the screen 3a, for example. That is, the condition detection timing is after the instruction is displayed on the screen 3a. Further, together with the instruction, the timing of the condition detection timing may be displayed on the screen 3a.

As an example, instructions to the user from the mobile terminal 3 are associated with a manga story. For example, if a scene in which the main character of a manga turns his back is set at a predetermined timing, and in this scene the user actually holds the mobile terminal 3 and turns his back along with the mobile terminal 3, Scroll. The scrolling condition in this case is that the acceleration sensor included in the mobile terminal 3 detects an acceleration of a predetermined value or more. That is, when the user turns around with the portable terminal 3 in his possession at the condition detection timing, and the acceleration sensor included in the portable terminal 3 detects an acceleration equal to or greater than a predetermined value that satisfies the scrolling condition, the manga scrolls.

In addition, in the case where the mobile terminal 3 is a head mounted display (HMD) and a manga is displayed on the display, when the user turns around at the condition detection timing, it is determined that the scrolling condition is satisfied and the manga display function is performed. may scroll the manga.

In this manner, the manga display function that performs conditional scrolling requires a new user operation or the like to scroll the manga, and thus enables the manga to be expressed with high interactivity for the user.

[1-4-6. effect]
The manga according to this embodiment may be given various effects (image effects). An effect is something that is applied to a part of a manga, and for example, a part of a manga scene (a part of the still image 52 that makes up the manga) is dynamically changed by the effect.

Note that the scene (still image 52) to which the effect is applied is set in advance together with the contents of the effect. The manga display function executes the effect set for the scene at the timing when the scene for which the effect is set is displayed on the screen 3a.

More specifically, some of the images that make up the manga are video images, and the manga display function is an effect that starts playing the video when the video is displayed by scrolling, and ends the video playback. Then, the user may scroll to the next still image 52. That is, the manga may include a moving image between the still images 52 .

Further, the manga display function may cause the predetermined still image 52 to be enlarged/reduced, vibrated vertically and horizontally, or rotated as an effect. Further, the manga display function may have an effect in which a predetermined still image 52 displayed on the screen 3a is faded out, the next still image 52 is faded in, and the still image is displayed on the screen 3a.

Further, the manga display function may display another still image superimposed on the predetermined still image 52 as an effect. For example, after the still image 52 including a person is displayed, a still image showing a speech bubble may be displayed superimposed on the still image 52, or a still image showing another person, etc. may be displayed.

In addition, in a part of the still images 52 constituting the manga, a still image 52 that is pseudo-different in the depth direction (or in the front direction) with respect to the screen 3a is arranged, and the manga display function is used as an effect in the depth direction of the screen 3a. A plurality of still images 52 pseudo-arranged may be sequentially displayed on the screen 3a. In other words, this effect is to display a plurality of still images 52 one after another on the screen 3a as if it were a picture-story show.

In this way, the manga display function that performs effects enables more diverse expressions for manga.

In step 104, the scroll control unit 62 scrolls the manga displayed on the screen 3a.

In the next step 106, the rotation notification unit 64 determines whether or not the manga displayed on the screen 3a has reached the notification timing of the rotation notification image 54, and in the case of an affirmative determination, the process moves to step 108, and in the case of a negative determination, The process moves to step 114.

In step 108, the rotation notification unit 64 displays the rotation notification image 54 on the screen 3a.

In the next step 110, the rotation determination unit 66 determines whether or not the screen 3a (mobile terminal 3) has rotated, and in the case of an affirmative determination, the process moves to step 112. On the other hand, in the case of a negative determination, the process returns to step 108, and the display of the rotation notification image 54 by the rotation notification unit 64 is continued.

In step 112, the rotation notification unit 64 stops displaying the rotation notification image 54 on the screen 3a, thereby making the rotation notification image 54 non-display.

In the next step 114, the effect control unit 68 determines whether an effect is set on the manga scene displayed on the screen 3a, and if the determination is affirmative, the process moves to step 116; if the determination is negative, The process moves to step 118.

In step 116, the effect control section 68 executes the effect set for the manga scene displayed on the screen 3a.

In step 118, the manga display control unit 60 determines whether or not the manga displayed on the screen 3a has ended, and if the determination is positive, the manga display process is ended, and if the determination is negative, the process moves to step 102. and continue displaying the manga. As an example, the manga display control unit 60 determines that the manga has ended when the manga displayed on the screen 3a cannot be scrolled any further.

As described above, the mobile terminal 3 according to the present embodiment displays a manga formed by a plurality of continuous still images 52 on the screen 3a. The manga display process then scrolls the manga displayed on the screen 3a in one direction, and sends a rotation notification to prompt the user to horizontally rotate a predetermined angle using the screen 3a as a reference plane, depending on the progress of the manga. This is done at a predetermined notification timing.

As a result, even if the scrolling direction of the manga displayed on the screen 3a is one direction, the mobile terminal 3 allows the user to horizontally rotate the screen 3a to change the scrolling direction of the manga up, down, left, right, or diagonally based on the user's viewpoint. It becomes possible to change the direction in various directions. Therefore, the mobile terminal 3 allows, for example, the manga displayed on the screen 3a to be expressed in a manner similar to a moving image, and as a result, the manga displayed on the screen 3a can be expressed in a greater variety of ways. .

[2. Second embodiment]
A second embodiment of the present invention will be described below.

The configurations of the manga distribution system 1, server 4, and mobile terminal 3 according to the present embodiment are the same as those of the manga distribution system 1, server 4, and mobile terminal 3 according to the first embodiment, so the explanation will be omitted. .

The manga display function according to this embodiment scrolls the still image 52 at a predetermined speed (hereinafter referred to as "scroll speed"). That is, the manga display function according to the present embodiment automatically scrolls the manga displayed on the screen 3a based on the scrolling speed (hereinafter referred to as "automatic scrolling"). Note that the scroll speed is set for each still image 52 in the manga data 50, for example. Then, the scroll control unit 62 reads the scroll speed set in the manga data 50, and scrolls the still image 52 displayed on the screen 3a at the read scroll speed. Further, the present invention is not limited to this, and a constant scrolling speed may be set for the entire manga data 50, or a plurality of consecutive still images 52 may be grouped, and the scrolling speed may be set for each group.

Further, the manga display function according to the present embodiment performs either scroll stop control or scroll continuation control.

The scroll stop control according to the present embodiment stops automatic scrolling of the manga until the screen 3a rotates when the manga displayed on the screen 3a is rotated, and stops automatic scrolling of the manga after the screen 3a rotates. Let it restart. The scroll continuation control according to the present embodiment continues automatic scrolling regardless of whether or not the user rotates the screen 3a, even when the manga displayed on the screen 3a is rotated.
