  The present invention relates to a display processing method on a display unit of a mobile communication terminal device, and a mobile communication terminal device using the display processing method.

  Conventionally, mobile communication terminal devices such as mobile phone devices have been widely used. In recent years, there has been remarkable progress in technology related to mobile communication terminal devices, and in recent years, in addition to the normal call function and e-mail function, digital content acquired via a web browser function, a network, or via a recording medium. A model equipped with a function to display images has also been put into practical use.

JP 2001-249658 A JP 2004-260431 A

  The above-described conventional technique is a technique that has a display unit having a sufficiently large display surface and is compatible with a personal computer or the like to which a keyboard and a mouse can be connected as standard. In addition, many web page images and digital content images are created so as to fit the size of the display surface in a personal computer.

  When displaying a display target image adapted to the size of the display surface in such a personal computer in an environment where only a small display surface can be used, such as a mobile communication terminal device such as a mobile phone device, only a small part of the display target image is displayed. Cannot be displayed. For this reason, in order to display a desired region in the display target image on the display surface of the mobile communication terminal device, a situation in which it is necessary to change the display target region often occurs.

  In such a case, if a pointing device such as a mouse can be used, it is considered that the display target area can be changed relatively easily. However, a small mobile communication terminal device such as a mobile phone device is usually used for input. The device generally has only a stroke device with a plurality of small keys. Accordingly, in order to change the display target area to a desired area in a small mobile communication terminal device such as a mobile phone device, it is often necessary to press a small key many times. It was very inconvenient for the user to press these small keys many times.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a display processing method capable of easily changing display contents on a display unit of a mobile communication terminal device.

  Another object of the present invention is to provide a mobile communication terminal device that can easily change the display content on the display unit.

  From a first aspect, the present invention is an image display processing method used in a mobile communication terminal device, the posture detection step of detecting the posture of the mobile communication terminal device; and detected in the posture detection step. An out-of-predetermined range determination step for determining whether the determined posture is outside a predetermined posture range including a reference posture; and the detected posture when the result of the determination in the posture determination step is affirmative And a region control step of continuously changing the display target region of the image displayed on the display unit of the mobile communication terminal device in correspondence with the relationship between the reference posture range and the reference posture range.

  Here, “the posture is inside the predetermined posture range” means, for example, when the predetermined posture range has an inclination angle of −10 ° or more and 10 ° or less from the reference posture of the mobile communication terminal device. The case where −10 ° ≦ θ ≦ 10 ° is satisfied when the inclination angle value is θ. Also, “the posture is outside the predetermined posture range” means that, for example, when the predetermined posture range has an inclination from the reference posture of the mobile communication terminal device of −10 ° or more and 10 ° or less, When the angle value is θ, θ <−10 ° or θ> 10 ° is satisfied. In this specification, the terms “inside the posture range” and “outside the posture range” are used in this sense.

  In this display processing method, the posture of the mobile communication terminal device is detected in the posture detection step. Subsequently, in the determination step outside the predetermined range, it is determined whether or not the posture detected in the posture detection step is outside the predetermined posture range. Here, the predetermined posture range is determined by experiments and experiences from the viewpoint of operability. The predetermined posture range may be fixedly set in advance or may be set by the user.

  If the result of the determination in the out-of-predetermined range determination step is affirmative, the display target region displayed on the display unit of the mobile communication terminal device is continuously displayed in the region control step corresponding to the change direction of the posture. To change. For this reason, the user can continuously change the display target area displayed on the display unit with a simple operation of changing the attitude of the mobile communication terminal device. Therefore, according to the display processing method of the present invention, it is possible to easily change the display target area continuously.

  In the display processing method of the present invention, in the region control step, along the direction corresponding to the difference value at a speed corresponding to the difference value from the posture detected in the posture detection step and the posture range from the inside. Thus, the display target area can be changed.

  Here, the “difference value” refers to an inclination corresponding to the boundary between the inner side of the posture range and the outer side of the posture range from the value of the inclination angle of the mobile communication terminal device when the mobile communication terminal device is outside the predetermined posture range. It is a signed value obtained by subtracting the corner value. For example, when the difference value is positive, it indicates that the mobile communication terminal device has rotated rightward from the reference posture, and when it is negative, the mobile communication terminal device has leftward from the reference posture. Shown rotated. In this specification, the term “difference value” is used in this sense.

  In this case, when the posture is outside the predetermined posture range, along the direction corresponding to the difference value at the speed corresponding to the difference value between the current posture and the reference posture in the region control step, The display target area in the display unit is continuously changed. Therefore, by adjusting the direction and magnitude of the inclination of the mobile communication terminal device from the reference posture, the display target area can be continuously changed in the desired direction at the desired speed.

  In the display processing method of the present invention, an acceleration detection step of detecting acceleration in a direction orthogonal to the display surface of the display unit; whether the magnitude of the acceleration detected in the acceleration detection step exceeds a predetermined value An acceleration determining step for determining whether the display magnification of the display unit of the mobile communication terminal device is changed corresponding to the direction of the acceleration when the determination result in the acceleration determining step is affirmative And a control step.

  In this case, in the acceleration detection step, acceleration in a direction orthogonal to the display surface of the display unit of the mobile communication terminal device is detected. Subsequently, in the acceleration determination step, it is determined whether or not the magnitude of the acceleration detected in the acceleration detection step exceeds a predetermined value. Here, the predetermined value is determined by experiment and experience from the viewpoint of operability. The predetermined value may be fixedly set in advance or may be set by the user.

  If the result of the determination in the acceleration determination step is affirmative, a new display magnification is first determined based on the current display magnification and the direction of acceleration in the magnification control step. Then, an image is displayed at a new display magnification. Therefore, the display magnification can be changed by a simple operation of moving the mobile communication terminal device in a direction orthogonal to the display surface at an acceleration exceeding a predetermined value.

  Here, in the magnification control step, the display magnification of the display unit of the mobile communication terminal device can be changed by a magnification corresponding to the magnitude of the acceleration. In this case, the amount of change in display magnification can be adjusted by adjusting the acceleration of movement along the direction orthogonal to the display surface of the mobile communication terminal device.

  In this case, in the position detection step, a position in a direction perpendicular to the display surface of the mobile communication terminal device in the reference posture is detected, and the display on the display unit is continuously changed at a magnification corresponding to the position. For this reason, the display magnification can be continuously changed easily by changing the position in the direction orthogonal to the display surface of the mobile communication terminal device.

  Further, in the display processing method of the present invention, the rotation angle from the reference posture around at least one of the display vertical axis and the display horizontal axis in the reference posture of the mobile communication terminal device is less than or equal to a predetermined value. Range.

  Here, the reference posture can be a posture in which the display surface of the display unit is horizontal. Further, prior to the posture angle detecting step, an initial posture detecting step of detecting the initial posture of the mobile communication terminal device can be further provided, and the reference posture can be set as the initial posture.

  According to a second aspect of the present invention, a display unit that displays an image; attitude detection means that detects an attitude; and whether or not the attitude detected by the attitude detection means is outside a predetermined attitude range. A non-predetermined range determination unit; and a display target region of the display unit corresponding to a relationship between the posture and the predetermined posture range when a result of the determination by the out-of-predetermined range determination unit is affirmative And a region control means for continuously changing the mobile communication terminal device.

  In this mobile communication terminal device, the posture detection means detects the posture of the mobile communication terminal device. Subsequently, the out-of-predetermined range determination unit determines whether or not the posture detected by the posture detection unit is outside the predetermined posture range. If the result of the determination by the out-of-predetermined range determination means is affirmative, the area control means continuously changes the display target area on the display unit corresponding to the relationship between the posture and the predetermined posture range. Let

  That is, the mobile communication terminal apparatus of the present invention can continuously change the display target area of the display unit by using the display processing method of the present invention described above. Therefore, according to the mobile communication terminal device of the present invention, it is possible to easily change the display target area continuously in a desired direction.

  In the mobile communication terminal device according to the present invention, the area control unit may determine the difference between the posture detected in the posture detection step and the reference posture when the result of the determination by the out-of-predetermined range determination unit is positive. The display target area can be changed along a direction corresponding to the difference value at a speed corresponding to the value.

  In this case, when the result of the determination by the out-of-predetermined range determination unit is affirmative, the area control unit is at a speed corresponding to the difference value between the posture detected in the posture detection step and the reference posture. The display target area displayed on the display unit is continuously changed along the direction corresponding to the difference value. Therefore, by adjusting the direction and magnitude of the inclination of the mobile communication terminal device from the reference posture, the display target area can be continuously changed in the desired direction at the desired speed.

  In the mobile communication terminal device of the present invention, acceleration detection means for detecting an acceleration in a direction orthogonal to the display surface of the display unit of the mobile communication terminal device; and the magnitude of the acceleration detected by the acceleration detection means. , An acceleration determination unit that determines whether or not a predetermined value is exceeded; and a magnification control unit that changes a display magnification of the display unit in accordance with the direction of the acceleration. .

  In this case, the acceleration detection means detects the acceleration in the direction orthogonal to the display surface of the display unit of the mobile communication terminal device. Subsequently, the acceleration determination means determines whether or not the acceleration detected by the acceleration detection means exceeds a predetermined value. If the determination result is affirmative, the magnification control means changes the display magnification corresponding to the direction of acceleration of the mobile communication terminal device. Therefore, the display magnification can be changed by a simple operation of moving the mobile communication terminal device in a direction orthogonal to the display surface at an acceleration exceeding a predetermined value.

  Here, the magnification control means may determine the display magnification based on the magnitude of acceleration and the direction of acceleration. In this case, the amount of change in display magnification can be adjusted by adjusting the acceleration of movement along the direction orthogonal to the display surface of the mobile communication terminal device.

  Further, in the mobile communication terminal device of the present invention, position detection means for detecting the position of the mobile communication terminal device in a direction orthogonal to the display surface of the display unit in a reference posture; at the position detected by the position detection means Correspondingly, a magnification control means for changing a display magnification in the display section can be further provided.

  In this case, the position detection unit detects the position of the mobile communication terminal device in a direction orthogonal to the display surface of the display unit in the reference posture. Then, the magnification control unit displays an image on the display unit at a display magnification corresponding to the position detected by the position detection unit. For this reason, the display magnification can be continuously changed easily by changing the position in the direction orthogonal to the display surface of the mobile communication terminal device.

First, the non-rotating state of the mobile phone device 10 relating to the rotation of the mobile phone device 10 about the Y S axis in the coordinate system X S Y S Z S which is the XYZ coordinate system when the mobile phone device 10 is in the XY reference posture, right The definition of the rotation state and the left rotation state will be described. These non-rotation state, right rotation state, and left rotation state are defined corresponding to the rotation angle θ Y of the mobile phone device 10 around the Y S axis, as shown in FIG. That is, the case where the rotation angle θ Y around the Y S axis of the mobile phone device 10 is clockwise (clockwise) between the angle θ Y0 and 90 ° or less is defined as the right rotation state. Further, the case where the rotation angle θ Y around the Y S axis of the mobile phone device 10 is counterclockwise (counterclockwise) is an angle θ Y0 or more and less than 90 ° is defined as a left rotation state. And the case where it is neither a right rotation state nor a left rotation state is defined as a non-rotation state.

Further, when the portable telephone apparatus 10 is in a rotating state, the Y S axis of the mobile phone device 10 from the rotation angle theta Y in FIG. 4 (A), the value obtained by subtracting the value of the angle theta Y0, Y S axis It is defined as the rotation angle θ YD around.

Next, a non-rotating state of the cellular telephone apparatus 10 relating to rotation of the X S axis portable telephone apparatus 10 in the coordinate system X S Y S Z S is a XYZ coordinate system when the cellular phone unit 10 is in the XY reference attitude, The definitions of the pre-rotation state and the post-rotation state will be described. These non-rotating state, pre-rotation state, and post-rotation state, as shown in FIG. 4 (B), are defined to correspond to the rotation angle theta X of the portable telephone apparatus 10 X S axis. That is, a case where the rotation angle θ X around the XS axis of the mobile phone device 10 is forward (clockwise in FIG. 4B) is an angle θ X0 or more and 90 ° or less is defined as a pre-rotation state. Also, if X S axis of the rotation angle theta X of the portable telephone device 10 is Atomawari angle theta X0 or less than 90 ° (counterclockwise in FIG. 4 (B)), it is defined as post-rotation state . And the case where it is neither a front rotation state nor a back rotation state is defined as a non-rotation state.

Further, when the portable telephone apparatus 10 is in a rotating state, the X S axis of the mobile phone device 10 from the rotation angle theta X in FIG. 4 (B), the value obtained by subtracting the value of the angle theta X0, X S axis Rotational displacement angle θ XD is defined.

The angles θ Y0 and θ X0 are determined in advance by the designer of the display control application 32. In the present embodiment, the angles θ Y0 and θ X0 are set to 10 °. In the present embodiment, the coordinate system X S Y S Z S is only required that the X S Y S plane is a horizontal plane. In the following description, the angle θ Y and the angle θ X are also referred to as an inclination angle θ Y and an inclination angle θ X.

Next, the acceleration state of the mobile phone device 10 employed in the display control application 32 will be described. As shown in FIG. 5, the acceleration state is defined corresponding to the acceleration along the Z S axis in the coordinate system X S Y S Z S when the mobile phone device 10 is in the XY reference posture. That is, the case where the magnitude of the acceleration α s along the Z S axis of the mobile phone device 10 exceeds α 0 (m / s 2 ) is defined as an acceleration state, and the magnitude of the acceleration α s is α 0.

It is detected whether it corresponds to either. Then, when the mobile phone device 10 is in a state other than the non-rotating state, the posture data processing unit 33 calculates a displacement angle θ YD or θ XD corresponding to the rotating state of the mobile phone device 10.

Here, the speed of movement is a speed corresponding to the magnitude of the displacement angle θ YD or θ XD . The area control unit 36 reports the calculated display target area to the display data generation unit 35.

The magnification control unit 37 calculates the display magnification based on the report result from the acceleration data processing unit 34. In calculating the display magnification, when the acceleration direction is the + Z S direction, the magnification control unit 37 sets the display magnification at a constant rate (for example, (1 / 1.5) times) than the current display magnification. Make it smaller. Further, when the acceleration direction is the + Z direction, the magnification control unit 37 increases the display magnification at a certain rate (for example, 1.5 times) than the current display magnification. The magnification control unit 37 reports the calculated display magnification to the display data generation unit 35.

  The display data generation unit 35 displays the display target image reported from the region control unit 36 at the display magnification reported from the magnification control unit 37 for the display target image stored in the display content storage region 24F. Generate display data. The display data generated in this way is sent to the display unit 13 and an image corresponding to the display data is displayed on the display unit 13.

  The sensor unit 25 detects the attitude angle of the mobile phone device 10 and the acceleration acting on the mobile phone device 10, and outputs the analog voltage signal as a sensor unit 26, and converts the voltage value of the voltage signal from the sensor unit 26 into a digital value. And an analog / digital (A / D) converter 27. Then, the digital data output from the A / D converter 27 is notified to the control unit 21 as measurement data. In addition, the sensor unit 25 starts to operate in response to a measurement start command from the control unit 21 and stops operating in response to a measurement stop command from the control unit 21.

The sensor unit 26 has a rotation angle (pitch) about the X C axis of the mobile phone device 10 in the XYZ reference coordinate system X C Y C Z C which is an XYZ reference posture in which the XY plane is a horizontal plane and the Y direction is a true north direction. Angle φ X ), rotation angle around Y C axis (roll angle φ Y ), and rotation angle around Z C axis (yaw angle φ Z ) are detected. Further, the sensor unit 26 detects acceleration in the X direction (α X ), acceleration in the Y direction (α Y ), and acceleration in the Z direction (α z ). The sensor unit 25 sets the pitch angle φ X , roll angle φ Y , yaw angle φ Z , X-direction acceleration α X , Y-direction acceleration α Y and Z-direction acceleration α z detected at each measurement time as one set. The control unit 21 is notified as measurement raw data.

[Operation]
Next, description will be given mainly focusing on display control on the display unit 13 by the display control application 32 in the mobile phone device 10 configured as described above.

  When the display control application 32 is activated, as shown in FIG. 6, the display control application 32 first performs posture measurement setting in step S11. Such setting is performed by the display control unit 35 sending a measurement data collection start command and a collection data condition to the measurement data collection processing unit 31.

  The measurement data collection processing unit 31 that has received the measurement start command sends an operation start command to the sensor unit 25. As a result, the sensor unit 25 starts an operation and starts an operation of periodically sending the measurement raw data to the control unit 21. Thereafter, in the control unit 21, the measurement data collection processing unit 31 receives the measurement raw data, performs offset correction and gain correction, and then starts an operation of storing the measurement data satisfying the collection data condition in the temporary storage area 24T. .

  Next, in step S <b> 12, the display data generation unit 35 displays the initial screen of the display unit 13. In this initial screen, content is acquired or referenced from a predetermined resource using data stored in the display content storage area 24F and displayed on the display unit 13.

  Next, in step S <b> 13, the display control application 32 determines whether or not the end key is pressed on the operation unit 12. If the result of this determination is affirmative, the display control application 32 ends the process. As a result, the execution of the display control application 32 ends.

  If the result of the determination in step S13 is negative, the process proceeds to step S14. In step S14, the rotation state and the acceleration state are detected. In the rotation state and the acceleration state, first, the display control application 32 sends a measurement data request specifying the notification data condition to the measurement data collection processing unit 31.

  The measurement data collection processing unit 31 that has received the measurement data request reports measurement data that satisfies the notification data condition to the display control application 32. In the display control application 32, the attitude data processing unit 33 and the acceleration data processing unit 34 receive measurement data reported from the measurement data collection processing unit 31, respectively.

Upon receiving the measurement data, the posture data processing unit 33 calculates the tilt angle θ Y and the tilt angle θ X of the mobile phone device 10. Subsequently, the posture data processing unit 33 determines that the mobile phone device 10 is in the non-rotation state, the right rotation state, the left rotation state, the front rotation state, and the rear rotation state based on the calculated inclination angle θ Y and inclination angle θ X. It is detected whether it corresponds to either. Then, when the mobile phone device 10 is in a state other than the non-rotating state, the posture data processing unit 33 calculates a displacement angle θ YD or θ XD corresponding to the rotating state of the mobile phone device 10. The type and displacement angle of the rotation state of the cellular phone device 10 obtained in this way are reported to the area control unit 36.

In addition, the acceleration data processing unit 34 that has received the measurement data calculates the acceleration α s . Subsequently, the acceleration data processing unit 34 detects whether the mobile phone device 10 is in a non-accelerated state or an accelerated state based on the magnitude of the acceleration α s .
