[0030]
The motion pattern analysis function 21c calculates the movement direction and the movement distance (movement amount) by integrating the three-dimensional acceleration detection value acquired from the acceleration detection unit 5 twice in time, and calculates the movement direction and the movement direction. Based on the amount of movement, the pattern of physical operation (movement) applied to the terminal is analyzed.

[0032]
The reproduction control means 21b controls the reproduction state of audio data such as voice and music output from the speaker 32 according to the movement pattern analyzed by the movement pattern analysis function 21c.
[0033]
Next, display control operations and playback control operations in the mobile phone terminal configured as described above will be described. FIG. 2 is a schematic diagram showing the relationship between the physical movement applied to the terminal and the display control operation, and FIGS. 3 to 7 are flowcharts showing the control procedure and control contents.
[0034]
(1) Movie display control operation
Assume that moving image data received from a communication partner terminal or a site on a communication network or moving image data stored in the memory unit 26 is displayed on the LCD 34. In this case, the user first selects the moving image display operation mode at 35 using the key input unit. Then, whether to use the key operation mode or the acceleration sensor operation mode as the operation mode for moving image display control is designated and input.
[0035]
When the main control unit 21 detects that the moving image display operation mode is selected, as shown in FIG. 3, first, in step 3a, the key operation mode is designated as the operation mode for moving image display control or the acceleration sensor. It is determined whether an operation mode is specified. If the acceleration sensor operation mode is designated, the process proceeds to step 3b where the detection value of the acceleration sensor 51 representing the current position of the terminal is fetched from the acceleration detection unit 5 and stored as an initial value. To do.
[0036]
Next, the main control unit 21 determines whether or not the terminal has been moved by the user by monitoring the detection value of the acceleration sensor 51 in step 3c. When it is detected that there is a movement, the process proceeds to step 3d, where the movement pattern is analyzed to determine whether the movement pattern is a rotation operation as shown in FIG. If it is a rotation operation, it is determined that the operation is for moving image display control, and the process proceeds to step 3e, where it is determined whether the rotation direction is the vertical direction or the horizontal direction. As a result of this determination, if the rotation direction is the vertical direction, the process proceeds to playback / pause control, while if the rotation direction is the horizontal direction, the process proceeds to fast forward / rewind control.
[0037]
First, the reproduction / pause control will be described. In this case, as shown in FIG. 4, the main control unit 21 first determines in step 4a whether or not the rotation angle is greater than or equal to a predetermined angle. It is determined whether or not the above has continued. As a result of the determination, if the rotation angle is less than the predetermined angle or if the rotation duration is less than the predetermined time, it is determined that the rotation operation of the terminal at this time is a camera shake or a simple shake, and the step of FIG. Return to 3b. That is, these determinations eliminate user shakes and shaking.
[0038]
On the other hand, if the result of the determination is that the rotation angle is greater than or equal to a predetermined angle and the rotation duration is greater than or equal to a predetermined time, the main control unit 21 instructs the terminal to play or pause the rotation operation applied at this time. Judging what to do. Then, in step 4c, it is determined whether the rotation direction is the forward direction as shown in FIG. 2 or the backward direction. If it is the forward direction, reproduction of moving image data is started in step 4d. Note that if the reproduction has already been performed, the reproduction operation is continued. On the other hand, if the rotation direction is the backward direction, the reproduction operation is temporarily stopped, and if the rotation is stopped, the stop operation is continued.
[0039]
In addition, when a rotation operation in the reverse direction of the terminal is detected immediately after performing the above reproduction / pause, this reverse rotation operation is a part of the operation for reproduction / pause (return operation). Ignore it and ignore it.
[0040]
Now, suppose that the user has performed an operation of rotating the terminal in the horizontal direction in order to fast forward or rewind as shown in FIG. Then, the main control unit 21 detects this horizontal rotation operation in step 3e, and executes the fast forward / rewind control shown in FIG.
[0041]
That is, first, at step 5a, it is determined whether or not the rotation angle is equal to or greater than a predetermined angle. As a result of the determination, if the rotation angle is less than the predetermined angle or if the rotation duration is less than the predetermined time, it is determined that the rotation operation of the terminal at this time is a camera shake or a simple shake, and the step of FIG. Return to 3b. In other words, the user's hand shake and shaking are eliminated even with this horizontal rotation.
[0042]
On the other hand, as a result of the determination, it is assumed that the rotation angle is equal to or greater than a predetermined angle and the rotation duration is equal to or greater than a predetermined time. Then, the main control unit 21 determines that the rotation operation applied to the terminal at this time instructs to fast forward or rewind. Then, in step 5c, it is determined whether the rotation direction is rightward as shown in FIG. 2 or leftward. If it is rightward, fast-forwarding of moving image data is started in step 5e. On the other hand, if the rotation direction is the left direction, the process proceeds to step 5d where rewinding is performed. Note that these fast forward and rewind operations are performed both during reproduction of moving image data and during stoppage.
[0043]
Also, assume that during these fast forward or rewind, the user rotates the terminal in the reverse direction and returns it to the position before fast forward or rewind. The main control unit 21 detects this reverse rotation operation in step 5f, and proceeds to step 5g and step 5h. Here, whether or not the rotation angle is equal to or greater than a predetermined angle, and the rotation operation equal to or greater than the predetermined angle continues for a predetermined time or more Each of them is determined. As a result of this determination, if the rotation angle of the reverse rotation operation is less than a predetermined angle, or if the rotation duration is less than a predetermined time, it is determined that the reverse rotation operation of the terminal at this time is a camera shake or a simple shake. To do.
[0044]
On the other hand, if the rotation angle of the reverse rotation operation is equal to or greater than a predetermined angle and the rotation duration is equal to or greater than a predetermined time, the main control unit 21 performs fast-forward or rewind the reverse rotation operation applied to the terminal at this time. Judge that stop is instructed. Then, the process proceeds to step 5i where the fast-forwarding or rewinding of the moving image data is stopped, and the original state, that is, the reproduction or stop state is restored.
[0045]
Thus, reproduction and pause of moving image data, and fast forward and rewind operations are performed in the acceleration sensor operation mode, respectively. If the key input mode is selected as the operation mode, a known key operation is performed.
[0046]
(2) Standby screen display control
Generally, in a mobile phone terminal, a screen for standby is displayed on the LCD 34 when communication or image reproduction is completed. However, when the mobile phone terminal is carried in a pocket or bag, it is not always necessary to display this standby screen. Therefore, the cellular phone terminal according to the present invention is provided with a function of controlling the display off and on of the standby screen in the acceleration sensor operation mode.
[0047]
That is, when the user sets the acceleration sensor operation mode as the operation mode in the standby state, the main control unit 21 detects this setting in step 6a as shown in FIG. 6 and proceeds to step 6b, where the acceleration detection unit 5 Then, the detected value of the acceleration sensor 51 representing the current position state of the terminal is taken in and stored as an initial value.
[0048]
Next, the main control unit 21 determines whether or not the terminal has been moved by the user by monitoring the detection value of the acceleration sensor 51 in step 6c. When it is detected that there has been a movement, the process proceeds to step 6d where the movement pattern is analyzed to determine whether the movement pattern is an instantaneous operation that moves more than a certain amount within a certain time. . If it is a momentary operation, the process proceeds to step 6e, and the movement pattern at this time is compared with the movement pattern registered in advance by the user. As a result of the comparison, if the two movement patterns match, it is determined in step 6f whether or not the screen is being displayed. If the standby screen is displayed as a result of this determination, the display of the standby screen is turned off in step 6h. On the other hand, if the standby screen is not displayed, the standby screen is displayed in step 6g.
[0049]
That is, when the user registers in advance a movement pattern for controlling on / off of the standby screen display in the terminal, the standby screen display can be turned on / off simply by shaking the terminal thereafter.
[0050]
(3) Incoming call notification control
In general, a mobile phone terminal selectively uses a sound mode using sound and melody, a light emission mode using blinking of a lamp, and a vibration mode using a vibrator as incoming call notification modes. In particular, the vibration mode is often used as a manner mode. However, if the acceleration sensor operation mode is set while this vibration mode is used, the acceleration sensor may detect vibration of the vibrator in some cases, and erroneous display control or audio playback control based on the detection result. There is a worry that will be done.
[0051]
Therefore, in this embodiment, the function for preventing erroneous detection of the acceleration sensor 51 is provided in the incoming call notification control. That is, when an incoming call occurs in a standby state or during reproduction of image data or audio data, the main control unit 21 proceeds from step 7a to step 7b as shown in FIG. 7, and uses the vibrator 6 as an incoming call notification mode. Determine whether the vibration mode to be set is in progress. If the vibration mode is set, it is determined whether or not the acceleration sensor operation mode is set. If the acceleration sensor operation mode is set, the operation of the acceleration sensor 51 is stopped in step 7c.
[0052]
Instead of stopping the operation of the acceleration detection 5, the detection signal input from the acceleration detection unit 5 in the main control unit 21 is ignored or the detection signal from the addition degree detection unit 5 to the main control unit 21 is ignored. The input may be blocked.
[0053]
When the operation of the acceleration detection unit 5 is stopped, the main control unit 21 drives the vibrator 6 in step 7d to notify the incoming call. In this state, when the user performs an incoming call response operation or the caller abandons the call to stop driving the vibrator 6, the main control unit 21 detects this in step 7e and proceeds to step 7f. Here, the operation stop of the acceleration detector 5 is released.
If it does in this way, the fault by which the drive of vibrator 6 is erroneously detected in acceleration detection part 5 can be prevented.
[0054]
As described above, in the first embodiment, the acceleration sensor operation mode is provided as the operation mode, and in the state in which this mode is set, the movement of the main control unit 21 based on the value detected by the acceleration detection unit 5. The pattern analysis function 21c analyzes the movement pattern applied to the terminal. Then, according to the analyzed motion pattern, the display control function 21a and the reproduction control function 21b control the display state of moving image data and standby screen data associated with the motion pattern in advance.
[0055]
Therefore, according to this embodiment, the user can variously control the display state of the moving image data and the standby screen by moving the terminal up and down, left and right, tilting, and further rotating, for example. For this reason, it is possible to reduce the operational burden on the user who is handicapped, and it is possible to perform smooth control even when a healthy person is occupied with other work. Furthermore, there is an advantage that more various controls can be realized as compared to the case where all control of the display state of the image data and the standby screen is based on key operations.
[0056]
In the present embodiment, when the vibration mode is selected as the incoming call notification mode and the acceleration sensor operation mode is set as the operation mode, the operation of the acceleration detection unit 5 is stopped during the drive period of the vibrator 6. ing. Therefore, it is possible to prevent a problem that the driving of the vibrator 6 is erroneously detected in the acceleration detection unit 5, thereby improving the stability of display control in the acceleration sensor operation mode.
[0057]
(Second Embodiment)
The following various examples are conceivable as the second embodiment of the present invention.
[0058]
FIG. 8 shows the display result of the display control in the second embodiment. That is, in this example, as shown in FIG. 8A, when character data such as news is displayed on the display screen, if the terminal is shaken in a predetermined movement pattern, for example, leftward, it is displayed every time it is shaken. The character data inside is sequentially scrolled line by line downward in the screen as shown in FIGS. 8B and 8C.
[0059]
On the other hand, if the terminal is shaken in the right direction with a predetermined movement pattern, the character data being displayed is moved upward in the screen as shown in FIGS. Scrolls one line at a time.
It should be noted that the relationship between the direction of shaking the terminal and the direction of scrolling can be set in reverse.
[0060]
FIG. 9 shows the display result of the display control in the second embodiment. That is, in this example, as shown in FIG. 9A, when the (1) page of character data is displayed, if the terminal is shaken in a predetermined movement pattern, for example, the figure is displayed each time it is shaken. As shown in FIG. 9B, the display data is sequentially paged. On the other hand, if the terminal is shaken downward with a predetermined movement pattern, the display data pages are sequentially returned every time the terminal is shaken. In this example as well, the relationship between the direction of shaking the terminal and the direction of page turning can be set in reverse.
[0061]
FIG. 10 shows a display result of the display control in the third embodiment. That is, as shown in FIG. 10A, in the state where the terminal is set up, for example, the text of the mail is displayed horizontally on the display. In this state, when the terminal is laid down, the display direction of the mail text is switched accordingly as shown in FIG. In this way, each time the terminal is moved from the upright state to the sideways state, or from the sideways state to the upright state, the display direction of the mail body automatically changes accordingly, and the user particularly displays It is possible to always read and create a mail with an optimal display orientation without performing a key operation for switching.
[0062]
FIG. 11 shows a display result according to the fourth embodiment, which is a modification of the third embodiment. In this example, when electronic document data such as a novel is displayed, the electronic document data is displayed in a vertical writing mode when the terminal is set up, and when the terminal is laid down, the display direction of the electronic document data is switched accordingly. That is, in this embodiment, not only the display direction of the display data but also the sentence display method is switched from vertical writing to horizontal writing or from horizontal writing to vertical writing.
[0063]
In this way, in a mobile phone terminal equipped with a display having a longer vertical dimension than a horizontal dimension, document data can always be displayed in an optimum orientation in consideration of the display dimension. .
[0064]
FIG. 12 shows a display result of display control in the fifth embodiment. That is, when the display data as shown in FIG. 12A is displayed on the display of the terminal, when the terminal is moved by a predetermined amount in the direction approaching the user, the partial data indicated by the cursor in the display data is displayed. Is zoomed in as shown in FIG. Conversely, when the terminal is moved by a predetermined amount in the direction away from the user in the state of FIG. 12B, the display data is zoomed out to the state shown in FIG.
[0065]
(Other embodiments)
The present invention is not limited to the above embodiments. For example, in the first embodiment, the operation has been described focusing on the display control of moving image data and the display control of the standby screen. However, the acceleration is similarly applied to the case where audio data such as transmission / reception voice and music is reproduced and output. Regeneration control by the sensor operation mode can be applied.
[0066]
In the moving image data display control according to the first embodiment, the moving image data may be frame-forwarded or frame-returned when the terminal is instantaneously shaken in the left-right direction in the pause state.
[0067]
Further, in the standby screen display control according to the first embodiment, on / off of the standby screen display is controlled, but a plurality of standby screens, for example, a menu screen and a clock screen, are moved in a predetermined movement pattern. You may make it switch by this.
[0068]
Furthermore, in the second embodiment, the cursor position may be moved by tilting the terminal while displaying character data such as news and mail text. In this case, only the character designated by the cursor may be displayed in an enlarged manner than other characters. In this way, it is possible to display the character indicated by the cursor as if it were being followed by a loupe.
[0069]
Further, in each of the above embodiments, a mobile phone terminal has been described as an example. However, the present invention can be applied to other mobile communication terminals such as a personal digital assistant (PDA), and further, for example, MP3 or the like. The present invention can also be applied to a portable audio player corresponding to an audio encoding system, a voice recorder called a voice memo, a digital camera, or the like.
In addition, the configuration and display and playback control procedures and contents of the mobile communication terminal can be variously modified and implemented without departing from the gist of the present invention.
