  The electronic devices described in Patent Documents 1 and 2 reduce the sense of discomfort given to the user by filling in the difference between the user's operation speed and the drawing performance. However, the electronic devices described in Patent Literatures 1 and 2 cannot sufficiently reduce the sense of discomfort given to the user. For example, in the display device described in Patent Document 1, the number of times the user has pressed the operation unit is stored in order to return several characters so as to cancel out the amount of extra cursor movement. May not move to the assumed cursor position from the number of times the button is pressed, and as a result, the user may feel uncomfortable. Furthermore, in the portable terminal described in Patent Document 2, since the user scrolls from before the target position, the number of times the user who has recognized the scroll amount corresponding to the number of operations has pressed the operation unit is stored. In some cases, it takes time from the number of times the button is pressed down to the assumed scroll position, and as a result, the user may feel uncomfortable.

  Therefore, the present invention has been made in view of the above, and an object of the present invention is to provide a mobile terminal and a display control method capable of quickly displaying a desired display screen while avoiding giving the user a sense of incongruity. And

First, the outline | summary of the portable terminal which concerns on this embodiment is demonstrated with reference to FIG. FIG. 1 is a schematic diagram of the mobile terminal 1.

  As shown in FIG. 1, the mobile terminal 1 is a mobile terminal carried by a user, and includes an output device 15 that displays a screen. As the mobile terminal 1, for example, a mobile phone, PHS, PDA (Personal Digital Assistant) or the like is used. The mobile terminal 1 also includes an input device 14 for a user to operate a screen displayed by the output device 15. The input device 14 may be a touch screen type button displayed on the output device 15 as shown in FIG. 1, or may be an operation button or an operation wheel provided on the mobile terminal 1. The mobile terminal 1 has a function of moving the focus F to a predetermined position on the screen or scrolling the screen based on a user operation received by the input device 14.

  Next, details of the hardware configuration of the mobile terminal 1 will be described. FIG. 2 is a hardware configuration diagram of the mobile terminal 1. As shown in FIG. 2, the portable terminal 1 physically includes a main storage device such as a CPU 11, a ROM 12 and a RAM 13, an auxiliary storage device 17 such as a hard disk, etc. in addition to the output device 15 and the input device 14 described above. It is configured as a normal computer system including. Each function of the portable terminal 1 to be described later operates the input device 14 and the output device 15 under the control of the CPU 11 by reading predetermined computer software on the hardware such as the CPU 11, the ROM 12, and the RAM 13. This is realized by reading and writing data in the RAM 13 and the auxiliary storage device 17.

  FIG. 3 is a block diagram illustrating functions of the mobile terminal 1. As shown in FIG. 3, the mobile terminal 1 functionally includes a key input unit (operation unit) 20, a key input control unit 21, a control unit 22, a key input count unit (operation frequency acquisition unit) 23, display control. Unit (drawing unit) 24 and display unit 25.

  The key input unit 20 is a user interface corresponding to the input device 14 described above, and is configured to be able to input a focus position movement instruction or a screen scroll instruction on the screen by a user operation, for example. The key input unit 20 includes an up / down button for moving the focus position in the up / down direction of the screen, a left / right button for moving the focus position in the left / right direction of the screen, an up / down scroll button for scrolling the screen up / down, and a scroll of the screen in the left / right direction. A left / right scroll button is used. These upper and lower buttons or left and right buttons correspond to the first operation unit and the second operation unit in the claims.

  The key input control unit 21 has a function of analyzing a user operation received by the key input unit 20. For example, the key input control unit 21 has a function of determining whether or not the key input unit 20 is pressed and outputting the determination result to the control unit 22.

  The control unit 22 has a function of controlling each configuration of the mobile terminal 1. For example, the control unit 22 has a function of controlling the key input control unit 21 and the key input count unit 23 to operate in cooperation. In addition, the key input control unit 21 and the display control unit 24 have a function of controlling to operate in cooperation.

  The key input count unit 23 has a function of counting the number of operations of the key input unit 20 in a predetermined period based on the determination result output from the key input control unit 21. For example, the key input counting unit 23 refers to a value stored in the memory of the mobile terminal 1 and sets a period for counting the number of operations. This predetermined period may be a predetermined value (for example, 1 second), or may be settable by the user. The key input count unit 23 has a function of acquiring the number of times that the up / down button for moving the focus or scrolling the screen is pressed for a predetermined period.

  When it is determined that the operation button for moving the focus or the operation button for scrolling the screen is operated by the key input control unit 21, the display control unit 24 refers to the count value counted by the key input count unit 23, It has a function of calculating the focus movement position or the scroll position based on the movement amount corresponding to the value. The display control unit 24 has a function of causing the display unit 25 to display only the focus after movement or only the screen after scrolling without drawing the focus or scroll screen during movement.

  The display unit 25 is a user interface corresponding to the output device 15 described above, and for example, a liquid crystal display is used. The display unit 25 has a function of drawing based on a display instruction from the display control unit 24.

  Next, the operation of the mobile terminal 1 according to the present embodiment will be described. FIG. 4 is a flowchart showing the screen control operation of the mobile terminal 1. The control process shown in FIG. 4 is repeatedly executed at a predetermined interval from the timing when the mobile terminal 1 is turned on, for example. In view of ease of understanding, a screen control operation for moving the focus in the vertical direction will be described below.

  As shown in FIG. 4, first, key operation input processing is started (S10: input step). In the process of S10, the key input unit 20 and the key input control unit 21 input a user operation. For example, when the user presses an upper operation key that moves the focus position upward via the key input unit 20, the key input control unit 21 inputs the pressing of the upper operation key. When the process of S10 ends, the process proceeds to a count process (S12: operation number acquisition step).

  In the process of S12, the key input count unit 23 counts the number of operations within a predetermined period for each type or operation of the key input unit 20. For example, in the process of S10 within a predetermined period, the upper operation key for moving the focus position upward is continuously pressed three times, and then the focus position is moved downward by the user via the key input unit 20. When the lower operation key is pressed four times in succession, the upper operation key is counted 3 times and the lower operation key is counted 4 times. Then, the difference in the number of operations of the up / down operation keys is set as a count value. For example, when the number of operations of the upper operation key is 3 and the number of operations of the lower operation key is 4, the difference between the number of operations of the upper operation key and the number of operations of the lower operation key, that is, the lower operation key 1 The count is a count value in a predetermined period. Similarly, for example, when the user presses the upper operation key three times, the lower operation key four times, and the upper operation key five times in succession, the key input counting unit 23 calculates 2-4 + 5. The upper operation key is 3 times. If the number of operations of the up / down operation keys is the same, the count value in the predetermined period is 0. When the process of S12 is completed, the process proceeds to a focus movement process (S14).

  In the process of S14, the display control unit 24 calculates the focus movement position. The display control unit 24 calculates the amount of focus movement based on the count value counted in the process of S12. For example, the display control unit 24 calculates the focus movement amount by adding the count value to the movement amount per one operation of the upper operation key. For example, when the focus is set to move one line when the upper operation key is operated once, the count value becomes the movement amount as it is. The display control unit 24 calculates the focus movement position based on the current focus position and the calculated movement amount. When the process of S14 ends, the process proceeds to a drawing process (S16: drawing step).

  In the process of S16, the display control unit 24 causes the display unit 25 to display a screen in which the focus is moved to the focus movement position calculated in the process of S14. When the process of S16 ends, the control process shown in FIG. 4 ends.

  Thus, the control process shown in FIG. 4 is completed. By executing the control process shown in FIG. 4, when an operation key for moving the focus within a predetermined period is pressed, the drawing process is not performed for each operation, but the drawing is performed after a predetermined time. Processing is performed. The operation result will be described with reference to FIG. FIG. 5 is a schematic diagram for explaining the operation of the mobile terminal 1 and shows transition of screens. Here, it is assumed that the focus movement of one line is performed by one button operation, and the lower operation key is pressed five times. For example, in the case of a conventional portable terminal, or when the portable terminal 1 of the present embodiment is operated only once within a predetermined period, as shown in FIG. Drawing is performed in which the focus moves line by line from the position, and the focus sequentially moves to the line five lines below (screens 1 to 6). On the other hand, in the portable terminal 1 of the present embodiment, when the down operation key is pressed five times continuously within a predetermined period, as shown in FIG. 5B, the screen 2 shown in FIG. The focus movement of ˜5 is omitted, and the screen 2 after the focus is moved to the line below 5 is drawn.

  By the way, in the conventional portable terminal, the processing capability of the mounted CPU is limited from the viewpoint of terminal size restriction or terminal cost reduction, and as a result, when the operation key is pressed continuously several times The drawing ability may not catch up with the user's operation speed, and the focus may not move to an appropriate position. For example, even if the lower operation key is pressed 15 times within 3 seconds, the focus that should have moved by 15 lines may move only by 3 lines.

  On the other hand, according to the mobile terminal 1 and the display control method according to the present embodiment, an instruction to move the focus of the display unit 25 is input by the key input unit 20, and key input within a predetermined period by the key input count unit 23. The operation frequency of the unit 20 is acquired, and the display control unit 24 calculates the focus movement position based on the movement amount of the focus corresponding to the operation frequency, and the focus during the movement is drawn based on the calculated movement position. Only the focus after movement is drawn on the display unit. For this reason, even when the focus movement operation is continuously performed, the drawing during the movement of the focus can be omitted, so that a desired display screen can be quickly displayed. Furthermore, since the focus moves as many times as the number of times the user operates the operation unit, it is possible to match the focus movement amount assumed by the user with the actual focus movement amount. Therefore, it is possible to avoid giving the user a sense of incongruity.

  Furthermore, according to the mobile terminal 1 and the display control method according to the present embodiment, even when an operation in which a focus movement in the same direction and a focus movement in the opposite direction are mixed is input continuously, It is possible to quickly display a desired display screen while avoiding giving a sense of incongruity.

  In addition, embodiment mentioned above shows an example of the portable terminal and display control method which concern on this invention. The portable terminal and the display control method according to the present invention are not limited to the portable terminal 1 and the display control method according to the embodiment, and the portable terminal 1 according to the embodiment is within a range not changing the gist described in each claim. The display control method may be modified or applied to other methods.

  For example, in the above-described embodiment, the screen control operation for moving the focus in the vertical direction in FIG. 4 has been described. However, the screen control operation may be in the horizontal direction instead of the vertical direction. Moreover, although the operation of moving the focus has been described as an example in FIG. 4, the same applies to the scrolling of the screen. That is, in FIG. 4, the mobile terminal 1 inputs the scroll key operation in the process of S10, counts the number of scroll key operations in the process of S12, and calculates the scroll amount based on the count value in the process of S14. The scroll position is calculated based on the calculated scroll amount, and only the screen after scrolling is rendered in the process of S16. The operation result will be described with reference to FIG. FIG. 6 is a schematic diagram for explaining the operation of the mobile terminal 1 and shows transition of the screen. Here, it is assumed that one line is scrolled by one button operation, and the lower operation key is pressed five times. For example, in the case of a conventional mobile terminal or when the mobile terminal 1 of the present embodiment is operated only once within a predetermined period, as shown in FIG. 6A, the initial focus is set according to the number of operations. The drawing is performed by scrolling from the position line by line and sequentially scrolling down to the line five lines below (screens 1 to 6). On the other hand, in the portable terminal 1 of the present embodiment, when the down operation key is pressed five times continuously within a predetermined period, as shown in FIG. The screens 2 to 5 are omitted, and the screen 2 after scrolling is drawn on the lower line. As described above, as in the case of the focus movement operation, even when the scroll operation is continuously performed, drawing during the scroll can be omitted, so that a desired display screen can be displayed quickly. Is possible. Furthermore, since scrolling is performed by the number of times the user has operated the operation unit, it is possible to match the scroll amount assumed by the user with the actual scroll amount. Therefore, it is possible to avoid giving the user a sense of incongruity. Furthermore, even when an operation in which scrolling in the same direction and scrolling in the opposite direction are mixed is continuously input, a desired display screen is quickly displayed while avoiding the user from feeling uncomfortable. be able to.
