Abstract

PROBLEM TO BE SOLVED: To provide an image display control program and an image display control method capable of optimizing display control according to individual variation in posture of a user or the way the user moves a terminal, in image display control for changing display content depending on an attitude of the terminal, and to provide an image display device using the image display control program and the image display control method.SOLUTION: Attitude information of a device detected by an attitude detection unit is sequentially accumulated, and display control is performed using an image display feature associated with an index corresponding to a relative attitude of a portable terminal, among multiple image display feature information. When the portable terminal is rotated beyond an effective rotational angle, both or one of the effective rotational angle and the range of the effective rotational angle are updated. A reference attitude is redefined so that a position at the time before the excessive rotation is determined to have been finished becomes a new threshold value of the effective rotational angle. This processing enables optimized continuous images to be displayed quickly, regardless of the individual variation in the way the user operates the portable terminal.SELECTED DRAWING: Figure 7

Description

The present invention relates to an image display control program, an image control method, and an image display device including these in a terminal having a display, particularly a portable mobile terminal.

2. Description of the Related Art Conventionally, in a mobile terminal device equipped with a display such as a smartphone or a tablet terminal, display control of content including images, moving images, text, or a combination thereof is performed according to an input operation from the outside. As an external input operation means, various methods such as an operation using buttons, an operation on a touch screen, and voice input are employed. In addition, as control for image display, display control that gives a display change according to time series, for example, is employed instead of control that responds immediately to input.

Usually, such a mobile terminal device is provided with an acceleration sensor and a gyro sensor, and information on the attitude of the terminal can be acquired by these sensors. Several technologies that use this information for display control have been proposed. For example, Patent Literature 1 includes a display unit, a sensor that acquires attitude data of the display unit, and a display control unit that selectively switches content displayed on the display unit based on the attitude data. There has been proposed a portable terminal device characterized by the above.

Alternatively, in Patent Document 2, the rotation angle of the image display device or a sensor that detects information for calculating the rotation angle, and the display data based on the current angle of the image display device calculated based on input information from the sensor. A control unit that executes an update process; and a display unit that displays display data according to the update process of the control unit. The control unit is within an operation range when the image processing apparatus is within a predetermined operation range. The display data is updated according to the rotation angle at the display unit, and when the image display device rotates beyond the set operation range, the operation range is changed along with the rotation, There has been proposed an image display device that performs an operation range update process for setting a current angle of the image display device within an update operation range.

However, in the configuration disclosed in Patent Document 1, content to be displayed is prepared in accordance with a reference angle, for example, an inclination from a horizontal state, and thus the posture used by the user is not taken into consideration. . That is, the posture of the user when browsing the same content group varies, and there are users who browse while standing, and there are users who browse while lying on their backs. Appropriate display for such various users cannot be performed.

Further, the configuration disclosed in Patent Document 2 alleviates the problems in the configuration described in Patent Document 1 described above, but is not configured with a terminal that is often held in one hand, such as a smartphone or a tablet. For this reason, differences in how terminals are handled by individual users are not sufficiently considered, and display control in such terminals is not optimized. That is, the angle and speed at which the terminal is rotated by the user varies from person to person. However, in the image display device disclosed in Patent Document 2, the user who moves the terminal at a large angle is appropriate in a state where the user can visually recognize the display. Image display control is not performed. And often these users tend to move the terminal much larger if the display control is not done properly, so it is difficult to experience the desired image display, resulting in a loss of trust in the image display device. It will be connected.

The present invention has been made in view of the above problems, for example, in image display control that changes display contents according to the attitude of the terminal, in response to individual differences in the user's posture and how the user moves the terminal. An object of the present invention is to provide an image display control program for optimizing display control, an image display control method, and an image display apparatus including these.

In order to solve the above problems, an image display control program according to the present invention includes (1) one or a plurality of indexes and image display correspondence information corresponding to the indexes based on an external input. Image data reading means for reading image data, (2) reference attitude storage means for acquiring and storing the terminal attitude at a predetermined time point, and (3) determining an effective rotation angle according to the number of indexes included in the image data. Effective rotation angle determination means, (4) change amount accumulation means for accumulating and storing the inclination change amount of the terminal every predetermined time from the reference posture, and (5) the accumulated inclination change amount exceeds the effective rotation angle. (6) When it is determined by the over-rotation determination unit that the accumulated inclination change amount exceeds the effective rotation angle, a reference posture / effective rotation angle / effective Terminal posture determination control means for updating one or a plurality of rotation angle widths; (7) display image control means for controlling display of the read image data in accordance with the accumulated inclination change amount; It is made to function as a display means for displaying an image in a mode controlled by the display image control means (claim 1).

When updating the reference posture, the reference posture is updated so that a new effective rotation angle limit value is provided inside the terminal posture at the time when the over rotation determination means determines that the effective rotation angle has been exceeded. be able to. Further, when updating the effective rotation angle, the effective rotation angle is updated so that a new limit value of the effective rotation angle is provided inside the terminal posture at the time when it is determined by the over-rotation determination means that the effective rotation angle has been exceeded. can do. With such a configuration, when the user greatly tilts the terminal, the image display is not adjusted excessively, and the moving image display for the user is easily developed at an angle at which the user can optimally view the image.

In updating the effective rotation angle width, the effective rotation angle can be updated to a width wider than the effective rotation angle at the time when the over rotation determination means determines that the effective rotation angle has been exceeded. By adopting such a configuration, an image display that is optimized for the user who moves the terminal violently and that is moving for the user can be easily developed at an angle at which the user can visually recognize it optimally.

Further, the predetermined time point at which the reference posture is initially acquired can be configured as the time point when the image data reading unit reads the image data, or after the elapse of a predetermined period from the time point. Alternatively, it can be configured as an input time point at which image data is read or after a predetermined period has elapsed from that time point. Thus, when the user wants to browse desired visual content, the user inputs the image by clicking a button on the touch screen, etc., and receives the target image data through storage inside the terminal or communication with the outside of the terminal. When reading, since the input by the user is usually made by looking at the display, the reference posture is acquired at that time or after a slight time lag, so that the user's line of sight is almost directly facing the display. Since it can be set as a posture, it is easy for a user to develop a moving image display at an angle at which it can be viewed optimally.

Furthermore, the image display mode information can be configured to include at least a plurality of image groups and respective transmissivities. Each image display mode information is assigned an index, and an image to be displayed is controlled based on this and terminal posture information (inclination change amount). These images are changed and displayed, and an image display having movement for the user is developed. The image display mode information can also be configured to include at least one piece of image data and information related to the display area. Each image display mode information is assigned an index, and an image to be displayed is controlled based on this and terminal information (inclination change amount). The images are changed and displayed, and an image display that moves for the user is developed.

In the present invention,
(1) “Image data” includes image display mode information and an index associated therewith. The “image display mode information” can include a plurality of image groups, for example. In that case, the plurality of image groups may share the same frame, or the terminal postures by making the image groups relevant to each other, such as images with different viewpoints for the same object. It can be expected that the interest in image display in response to changes in the height will increase. Of course, the present invention is not limited to this, and a group of images that are conceptually relevant even if they are not structurally relevant or low can be used. Alternatively, it may be a set of a plurality of images that are not related to each other in terms of structure or concept. Furthermore, different display modes relating to a single image, for example, a change in display area, or a change in display color tone like a hologram can also be used.

(2) “Index” is defined in association with individual image display mode information. The effective rotation angle width of the image data is determined according to the number of indexes included in the image data. (3) The “reference posture” is defined as the terminal posture at the approximate center of the effective rotation angle.

(4) “Effective rotation angle” refers to an angle of a terminal posture at which image data is displayed with a change, and means a threshold value for a change in the terminal posture from the reference posture. The terminal posture is grasped by an acceleration sensor and / or a gyro sensor included in the terminal. The width of the effective rotation angle is defined by the number of image data indexes and the unit angle corresponding to one index.

As described above, according to the present invention, an image display having a motion for the user is displayed at an angle optimized in accordance with a change in the terminal posture that occurs based on the user's terminal operation. In particular, the reference posture, effective rotation angle, and width thereof are appropriately updated regardless of the number of indexes included in the image data, individual differences in how the user moves the terminal, or the posture in which the user handles the terminal. However, there is an increased possibility that it is possible to avoid display problems such that the user himself / herself cannot fully enjoy despite the fact that the image display is moving for the user.

[1 Functional configuration of terminal]
FIG. 1 is a view showing an appearance of a mobile terminal 100 according to an embodiment of the present invention ((A) front view, (B) plan view). On the front surface of the mobile terminal 100, a display unit 108 having a touch sensor 110a on the surface is provided. The display unit 108 is composed of a liquid crystal display. Although the viewing angle of the liquid crystal display varies depending on the driving method of the liquid crystal panel, in any driving method, the user can most easily see the display screen when facing the front of the mobile terminal 100.

FIG. 2 is a functional configuration diagram of the mobile terminal 100. As shown in FIG. 2, the mobile terminal 100 includes a communication unit 102, a posture detection unit 104 (acceleration sensor 104a, gyro sensor 104b), a control unit 106 including a central processing unit (processor), a display unit 108, An operation unit 110 (touch sensor 110a, operation button 110b) and a storage unit 112 are provided. The control unit 106 functions as a display control unit 106a, an effective rotation angle 106b, a posture information accumulation control unit 106c, and an over-rotation determination control unit 106d.

The communication unit 102 has an interface having at least one communication port, and controls information exchanged with other devices. The communication unit 102 is connected to be able to communicate with an information server or the like via, for example, a LAN (Local Area Network). An arbitrary system can be adopted for communication connection with an external node.

The acceleration sensor 104a is realized by, for example, a triaxial acceleration sensor or a biaxial acceleration sensor. The acceleration sensor 104a detects acceleration in each axial direction, and cannot detect rotational motion around the axial direction by itself.

The gyro sensor 104b is an inertial sensor that measures a rotational angular velocity, and a vibration gyro sensor that detects Coriolis force using a general IC type MEMS technology (Micro Electro Mechanical System) technology can be adopted.

The control unit 106 displays on the display unit 108 based on image information input via the communication unit 102, posture information of the mobile terminal 100 detected by the posture detection unit 104, and input operation information from the operation unit 110 described later. Effective rotation angle control for controlling the effective rotation angle stored in the storage unit 112 based on the determination result obtained by the display control unit 106a that controls the image data to be processed, the above-described attitude information, and the over-rotation determination control unit 106d described later Unit 106b, posture information accumulation control unit 106c that updates posture information stored in the storage unit 112 based on the posture information sequentially acquired, and whether or not the posture information exceeds a reference angle range. It has a function as 106d that is determined based on the reference angle range information stored in the storage unit 112 and the accumulated posture information.

The display unit 108 sequentially displays the image data controlled by the display control unit 108. Here, the display unit 108 and the touch sensor 110a in the operation unit 110 are arranged in a superimposed manner, and constitute an integrated touch screen. In addition, the portable terminal 100 according to the present embodiment is provided with a separate operation button 110b. Although not shown, an operation button such as a power button may be provided on the side surface of the mobile terminal 100 as appropriate.

The storage unit 112 includes a RAM, a ROM, a flash memory, an HDD, and the like. The storage unit 112 stores basic programs for starting up the mobile terminal 100, various application software, data thereof, and the like, as well as image information, attitude information of the terminal 100, information on the reference attitude, and effective rotation angle width. The

[2 Basic principles of image switching display]
Next, the basic principle of image switching according to the present invention will be described with reference to FIGS.
FIG. 3 is a conceptual diagram showing image data including a plurality of pieces of image display mode information each assigned an index (1, 2, 3,... N-1, n, n + 1,... 2n-1, 2n). FIG. 4 is a specific example of each image shown in FIG. 3, and FIG. 5 is a conceptual diagram showing the relationship between the rotation angle of the mobile terminal 100 and image switching. As shown in FIG. 3, each index is associated with information related to the display mode of each of the plurality of images. As shown in FIG. 4, each image is composed of images 1 to 2n having the same size, and these images are displayed in an overlapping manner in the same coordinates. In the present embodiment, image data is configured as an image group in which a plurality of images in which the sun is displayed on a mountain landscape and clouds are arranged by images are indexed. For example, in the index 1, the transparency of “image 1” is set to 0, and the transparency of other images (“image 2” to “image 2n”) is set to 1. As a result, as an image display mode corresponding to the index 1, “image 1” is visible on the display unit 108. Further, in an index n corresponding to a reference posture described later (baseline (0) shown in FIG. 5), the transparency of the image n is set to 0, and the transparency of other images is set to 1. As a result, the image n is displayed on the display unit 108 so as to be visible.

Here, the image switching control is performed based on the rotation angle change coefficient x (° / sheet) for switching the image to the next index, here the image n + 1, and the detected posture change of the mobile terminal 100. When the value obtained by dividing the detected rotation angle by x exceeds 1 (when rotation exceeding baseline (1) in FIG. 5 is detected), the transmittance of image n + 1 is set to 0, and the transmittance of other images is set. Set to 1. As a result, the display unit 108 displays the image n + 1 so that it can be viewed. In FIG. 5, for convenience of explanation, the rotation angle change coefficient x is illustrated as a large angle.

The effective rotation angle is determined by the number of indexes included in the image data and the rotation angle change coefficient x. That is, in this example, the effective rotation angle is 2 nx (°), and is −nx (°) to nx (°) when the reference state (baseline 0) is 0. In the case of continuous rotation in the same direction, the 2nth image is always displayed when the rotation exceeds the baseline (nx). In the case of reverse rotation, the displayed image changes in the same manner. When the image is continuously rotated in the same direction, the first image is always displayed when the baseline (−nx) is exceeded.

[3 Accumulation of change]
In addition, when the rotation angle of the mobile terminal 100 within a predetermined period is less than x, that is, when the mobile terminal 100 is rotated very slowly, the display image does not change even when the mobile terminal 100 is continuously rotated. It becomes. In order to prevent this, the change within a predetermined period is accumulated in the storage unit 112, and when the accumulation exceeds x, the image is changed to the next image.

[4 360 ° correspondence]
Next, a terminal attitude detection method according to the present embodiment will be described. The acceleration sensor 104a can detect the terminal posture at each time point by detecting the gravitational acceleration, and the gyro sensor 104b can detect the angular velocity in the three-axis directions by detecting the angular acceleration and integrating it. However, the OS (Operating Soft) installed in a general portable device has a different definition range of one circle depending on the type, so that the absolute terminal posture derived simply from the measured values of the acceleration sensor 104a and the gyro sensor 104b There are cases where image display control cannot be performed correctly. Therefore, the terminal attitude detection method according to the present embodiment employs the following technique.

That is, as shown in FIG. 6A, the terminal posture at the temporary point is set as a reference posture (= baseline), and the number of image display modes (number of indexes) and rotation angle change coefficient included in the image data for which display control is performed. Within the effective rotation angle based on x, display control is performed according to each image display mode included in the image data. The effective rotation angle when controlling display of 2n images is from -nx to nx. This basic structure does not depend on the angle that specifies the absolute terminal posture, but is detected as a relative rotation angle from the reference posture, which contributes to display control. Therefore, the display control can be optimized regardless of the reference posture of the mobile terminal 100 without depending on the OS or the sensor built in the terminal (FIG. 6B).

[5 User experience optimization]
Next, display control when the mobile terminal 100 rotates beyond the effective rotation angle will be described with reference to FIG.

As described above, the effective rotation angle range in the basic structure of image switching is defined by the number of images and the rotation angle change coefficient x. For example, when the user tilts the portable terminal 100 from the reference posture (baseline (0)) to the maximum effective rotation angle (baseline (nx)) at b1, an image corresponding to the index 2n is displayed on the display unit 108. The When the portable terminal 100 is moved to the position b2 while maintaining the tilted state of the portable terminal 100, that is, the state of exceeding the maximum value of baseline (baseline (nx)) in the state b1, the display unit 108 corresponds to the index 2n. The image continues to be displayed. At the same time, the reference posture is redefined at a position different from the terminal position b1. In other words, the position corresponding to the rotation angle (−nx) from the attitude of the mobile terminal 100 at the time point that is inward of the mobile terminal at the time of the completion of the movement, that is, in a time series before the time of continuous rotation is redefined as baseline (0). To do. As described above, when redefining baseline (0), a new limit value (here, baseline (nx)) of the effective rotation angle is provided inside the attitude of the mobile terminal 100 when it is determined that the baseline (0) is exceeded. By updating baseline (0), which is the reference posture, display control is performed so that image changes can be experienced more appropriately for the user.

At this time, when the user switches the image by tilting the mobile terminal 100, the perpendicular to baseline (0) (the normal to the plane parallel to the display unit 108) may not match the user's line of sight to the display unit 108. . In this state, even if the display changes according to the posture change of the mobile terminal 100 as the user's experience, the center is shifted with respect to the movement of the user's hand, and thus the user cannot visually recognize the display unit 108. There is a possibility that the image is switched depending on the state, and the display outside the effective rotation angle, that is, the fixed image with the index 1 or 2n is still displayed within the range that the user can see.

By controlling the effective rotation angle (−nx to nx) so that the user's line of sight to the display unit 108 and the perpendicular to the baseline (0) coincide with each other, the user's visibility is enhanced. This is because an equal number of images can be switched to the left and right with the center of movement of tilting the hand to the left and right as the reference axis.

However, in practice, since how the user moves the mobile terminal 100 varies from person to person, in the above control, the user's line of sight and the perpendicular to the baseline (0) are not always parallel. However, also in this case, if the mobile terminal 100 moves to the terminal position b2 and the baseline (0) is redefined, the baseline (0) is redefined and the baseline (0) is defined again when the mobile terminal 100 is tilted in the reverse direction. It will be. In this manner, the baseline (0) is corrected to the center of the tilt width of the user's mobile terminal 100 as much as the hand moves by tilting left and right.

Similarly, the same applies to the case where the portable terminal 100 is moved to the terminal position b3 while maintaining a state of being rotated in a more negative direction than the baseline (−nx) at the terminal position b1. That is, the position corresponding to the rotation angle (+ nx) is redefined as baseline (0) from the attitude of the mobile terminal 100 at the time point that is inside the mobile terminal attitude at the time of the movement completion, that is, the time series before the time when the mobile terminal is continuously rotated. .

In redefinition of baseline (0), in addition to the method of taking into account the terminal posture at the previous time point in time series that has been rotated as described above, the rotation angle (− (nx + α) from the terminal posture at the time of redefinition. ) (Where α is a constant) may be redefined as baseline (0). Furthermore, it is possible to redefine baseline (0) as a variable corresponding to a predetermined coefficient, for example, a frequency exceeding the effective rotation angle or an angular acceleration when the effective rotation angle is exceeded, instead of α being a constant. The same redefinition is possible when the rotation angle is exceeded in the negative rotation angle direction.

[Explanation using 6 flows]
A series of movements of the above-described image display control will be described along the flow of FIG.

The user performs an input to acquire image data by operating the mobile terminal. As an input method, for example, a touch operation of a button (not shown) for “acquiring image data” displayed on a touch screen constituted by the display unit 108 and the touch sensor 110a, or a press operation of the operation button 110b. This is realized by other predetermined operations. When an image data acquisition instruction is input (step S101: Yes), the mobile terminal 100 acquires image data from an external server via the communication unit 102 (step S102). As shown in FIG. 3, a plurality of pieces of image information and these pieces of image display mode information are associated with indexes in the image data.

Next, the portable terminal 100 acquires information on the current posture of the terminal from the acceleration sensor 104a (step S103). At the same time, the mobile terminal 100 defines the current posture as the reference posture. An effective rotation angle is defined based on the number of indexes included in the image data and the rotation angle change coefficient x (step S104). Here, the initial value of the rotation angle change coefficient x is stored in the storage unit 112 in advance.

In the present embodiment, the initial value of the rotation angle change coefficient x has been described as being stored in the storage unit 112 as an eigenvalue of this program. However, a different configuration, for example, image data acquisition as information constituting image data is obtained. It may be configured to be stored in the storage unit 112 sometimes. Such a configuration is effective, for example, when the image switching speed by rotation is optimized from the beginning according to the size when the difference in the number of image data indexes is significant.

Next, the display control unit 106a displays an image on the display unit 108 according to the image display mode selected from the acquired image data based on the current posture (step S105). The initial value is displayed in an image display mode associated with an index corresponding to baseline (0).

Next, a dynamic posture change of the mobile terminal 100 is detected by the gyro sensor 104b (step S106). What is detected here is a change in posture due to rotation of the mobile terminal 100. In the present embodiment, the description is based on the example of the image display change corresponding to the left and right rotation (roll axis) when the mobile terminal 100 is viewed from the front, but the present invention is not limited to this, and the vertical (pitch axis) is supported. The image display may be changed.

The detected information is stored cumulatively in the storage unit 112 (step S107). This is to prevent the orientation of the mobile terminal 100 from changing without changing the image display mode when the rotation speed is very slow, and the resulting image display mode is not changed. It is.

Next, the display control unit 106a determines whether the accumulated posture information matches the selected image display mode (step S108). When the current image display mode and the image display mode corresponding to the posture information are different (step S108 = No), an image display mode update process is performed (step S109).

Next, the excess rotation determination control unit 106d determines whether the accumulated posture information, that is, the relative rotation angle from the reference posture does not exceed the upper limit or lower limit of the effective rotation angle (step S110). When the upper limit or lower limit of the effective rotation angle is exceeded (step S110 = Yes), the process returns to step S105 after performing the above-described update processing of the effective rotation angle. If the accumulated posture information is within the range of the effective rotation angle, the process returns to step S105 as it is.

[7 Other Examples]
Next, another embodiment according to the present invention will be described. In the first embodiment described above, the reference attitude baseline (0) is redefined as a trigger when the attitude of the mobile terminal 100 changes after exceeding the effective rotation angle, whereby the absolute effective rotation angle transitions. The configuration has been described. Apart from this, or in combination with this, the following configuration may be adopted.

That is, in step S110, when it is determined that excessive rotation is detected by the excessive rotation determination control unit 106d, the rotation angle change coefficient x is redefined. Since the effective rotation angle is defined by the product of the index number of the image data and the rotation angle change coefficient, the rotation angle change coefficient is used to customize the width of the effective rotation angle according to how the user changes the attitude of the mobile terminal 100. Adjust the size of x. In adjusting the rotation angle change coefficient x, the magnitude of the rotation angle change coefficient x redefined according to the intensity of the movement of the user's hand can be adjusted. Specifically, the frequency of exceeding the effective rotation angle per unit time can be regarded as the intensity of movement, and the size can be adjusted accordingly, but even in that case, the rotation angle change coefficient x is excessively increased. Since an appropriate image display mode cannot be realized, x can be redefined as a non-linear function with a prescribed value, for example, a product of the number of images not exceeding 180 ° as a convergence value. .

Still another embodiment will be described with reference to FIG. FIG. 8 is a diagram showing a flow of image display control and is common to FIG. 7 in many steps. The description of common points is omitted. In the above example, it is defined that the attitude of the mobile terminal 100 exceeds the effective rotation angle as an update trigger for the effective rotation angle width. However, conversely, for example, when the movement of the hand is small and the change in the angle of the terminal is fine, it is possible to customize the movement of the user. Specifically, as shown in FIG. 8, when the rotation angle accumulation in a predetermined period is less than a predetermined value (step S210: Yes), the rotation angle change coefficient x is redefined (step S211). be able to. In this way, even when the effective rotation angle is not exceeded, by updating the effective rotation angle width, it is possible to realize more detailed user customization.

[8 Other Examples]
Furthermore, although the plurality of pieces of image display mode information included in the image data in the above-described embodiment are displayed in the same size and sequentially superimposed on the same coordinates, the image display mode information is not limited thereto. For example, as shown in FIG. 9, for each image information, it is defined which part is displayed in a frame for each index, and the displayed part in one image information is continuous according to the terminal posture. It can also be configured to be switched automatically. Alternatively, the focus degree of one image information may be defined together with an index, and the display mode may be switched according to the terminal posture. Furthermore, these are not one piece of image information, and a plurality of images may be displayed continuously for a plurality of indexes. Alternatively, the transparency of a plurality of images displayed with different transparency is not switched to zero sum, but the gradation is set in steps, so that the user can experience a more seamless image change. .
