Become.

Next, the best mode for carrying out the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of an embodiment of the present invention, and illustrates a configuration of a mobile phone 10 which is an example of an electronic device. As electronic devices, there are mobile terminals such as PDAs (personal digital assistants) and information processing apparatuses such as personal computers and server devices in addition to mobile phones. In addition, an electronic apparatus having a function of scrolling and displaying large information that cannot be displayed entirely on the screen size of the display device is an application target of the present invention.

  The present invention can be applied to automatic scrolling on an electronic device. When the user scrolls down one line, the user only has to press the down scroll key once. When scrolling two lines, the lower scroll key may be pressed twice. Further, when scrolling, the scroll key may be pressed as many times as necessary, but pressing the scroll key many times is troublesome for the user. Therefore, the scroll is continuously executed by continuously pressing the scroll key. This is called automatic scrolling.

  The cellular phone 10 includes a key input unit 11, a display unit 12, a communication unit 18, which functions including hardware means, a key event processing unit 13, a timer event processing unit 14, a display processing unit 15, and a scroll realized by a program. A processing unit 16 is included. Although not shown, the cellular phone 10 includes a CPU that executes a program and a storage unit that stores data such as the program and display data information 17. The present invention can also be applied to electronic devices other than the mobile phone 10 having the same configuration.

  The key input unit 11 is a key input device such as a keyboard, and has a key that indicates scrolling and its direction (for example, a direction key or the like corresponds to the scroll key hereinafter), and detects pressing / release of the key. It has a function of notifying the key event processing unit 13 together with scroll direction information. Release means that the user stops pressing the key and the key is released from the pressed state.

  The display unit 12 is a display device such as a liquid crystal display and has a function of displaying data instructed from the display processing unit 15. Note that hardware means for controlling an interface is provided between the key input unit 11 or the display unit 12 and the CPU, and between the key input unit 11 and the key event processing unit 13 and between the display unit 12 and the display processing unit 15. During this time, it is mediated by software or firmware such as a driver or OS (operating system), but these may be of ordinary function and will not be described.

  The communication unit 18 has a function of executing communication with a base station of a wireless telephone network at the time of Internet access, transmission / reception of an electronic mail, or a call. Since the wireless telephone network system has a function of connecting to the Internet and an e-mail function, the mobile phone 10 can acquire various contents from the outside via the base station and hold them in the storage means as display data information 17. . By using a storage medium such as a small memory card, contents can be acquired without using the communication unit 18.

  In an electronic device such as a personal computer, the communication unit 18 may have a function of connecting to another communication means such as a wired telephone network. In an electronic device that can display data on a medium such as a DVD (digital versatile disk) as display data information 17 as it is or an electronic device that generates display data by itself, the communication unit 18 is not included in the configuration. The present invention can also be applied.

  When the key event processing unit 13 receives a notification that the scroll key is pressed from the key input unit 11, the key event processing unit 13 notifies the scroll processing unit 16 of a key pressing event instructing execution of scrolling together with the scroll direction information. When the notification of the release of the key is received, the scroll processing unit 16 is notified of a key release event instructing to stop scrolling.

  Even when the mouse which is the position input device is operated instead of the key input unit 11 and an operation corresponding to pressing / release of the scroll key is performed, the key event processing unit 13 performs the key operation similarly to the operation of the key input unit 11. Notifies the scroll processing unit 16 of the press event / key release event. For example, even when an icon for executing a scroll operation is displayed on the display screen and operated with the mouse to perform an operation corresponding to pressing / release of the scroll key of the key input unit 11, the key event processing unit 13 performs the key press event. / Operate as a key release event.

  When the start timer or interval timer is started from the scroll processing unit 16, the timer event processing unit 14 counts timer notifications notified from the OS at regular intervals, measures the time, and determines each predetermined time. When the time has elapsed, a timer event is notified to the scroll processing unit 16. The timer event processing unit 14 stops the start timer and the interval timer by notifying the timer event, and stops the start timer or the interval timer designated by the timer stop instruction of the scroll processing unit 16.

  When the user presses the scroll key for a short time, the mobile phone 10 scrolls in a specified direction by a predetermined amount (for example, one line), and performs automatic scrolling that automatically repeats scrolling when the user presses the scroll key for a predetermined time or longer. The start timer is a timer for determining to shift to the automatic scroll state. The start timer is activated by a key press event, and when a predetermined time elapses after the activation, the timer event processing unit 14 notifies the timer event and notifies the automatic scroll state. Become. The interval timer is a timer that measures the interval at which scrolling is repeated.

  The display processing unit 15 displays data on the display unit 12 in response to a request including information on the position and size of data to be displayed from the scroll processing unit 16 and other processing units (not shown). When receiving a request from the scroll processing unit 16, the display processing unit 15 acquires data to be displayed from the content of the display data information 17 and displays it on the display unit 12.

  The scroll processing unit 16 starts scroll processing by a key press event, continues scrolling by a timer event, and ends scroll processing by a key release event. The scroll processing unit 16 sets the scroll amount for scrolling for each region, and controls the scroll speed. Detailed contents will be described in the description of the operation of the embodiment described later.

  Here, the scroll speed is determined by a value obtained by dividing the scroll amount by the time of the scroll interval. In the present invention, since the scroll interval is constant, the scroll amount corresponds to the scroll speed. As a method of setting the scroll speed, the scroll amount may be fixed and the scroll interval time may be set. When controlling the scroll speed by controlling the interval, the set value of the interval timer is set for each divided area instead of the scroll amount, and the scroll processing unit 16 notifies the timer event processing unit 14 of the set value. The interval timer may be set as the time for generating the timer event.

  The display data information 17 is displayed on the display unit 12 via the display processing unit 15 and display data such as content acquired from the outside via the communication unit 18, content generated internally, content on a storage medium, etc. Display control information. FIG. 2 is a diagram showing the configuration of the display data information 17.

  Display data is, for example, content that can be handled by web pages or e-mails on the Internet, content that consists of still images and characters, and content that can be displayed such as documents and images generated by users on electronic devices. What is necessary is just to display on the part 12, and the content is not limited. For example, the display data may be an address book that stores the contents of an e-mail, a telephone number, and a name, or a control screen when operating the mobile phone 10. However, the effect is not sufficiently exhibited when many scrolls are not required to view the entire display data. Even in the case of an electronic device having a display unit larger than that of a mobile phone such as a personal computer, the effect is not sufficiently exhibited when many scrolls are not required.

  The display control information includes a display requirement amount calculated according to the display start position S (address S) of the content and the scroll direction, and scroll information. The display start position S is in the content head position (address 0) in the initial state when the content is acquired, and moves in the scroll direction according to the scroll process. The display necessary amount is the data amount from the display start position S to the last position in the scroll direction of the content (in the case of scrolling in the vertical direction, the top T or the end B).

  The scroll information is created when the user presses the scroll key, and is referred to during automatic scrolling that automatically repeats scrolling when the user continues to press the scroll key. In the scroll information, the position of the area and the scroll amount are set for each area obtained by dividing the display necessary amount. In FIG. 2, the position of the first area is set to a0 and the scroll amount is set to n0, the position of the next area is set to a1 and the scroll amount is set to n1, and the scroll direction is set in the order of the areas. The position a0 is the display start position S when scrolling is started. When scrolling is repeated at regular intervals, the scroll amount corresponds to the scroll speed.

  FIG. 3 is a diagram showing an example of dividing into regions. FIG. 3 shows the entire content, and the display area indicates the size that can be displayed simultaneously on the display unit 12 without scrolling. FIG. 3 shows a state where the display start position S is moved from the initial address 0 to the lower position a0 by scrolling.

  FIG. 3 shows the state of scroll information when scrolling downward is started with respect to the current state. The display necessary amount is “B-S” between the content last position B and the display start position S. The area is divided into five equal parts of D0 to D4, and the scroll amount n0 to n4 of each area is n0 = 1 line. , N1 = 2 lines, n2 = 4 lines, n3 = 2 lines, and n4 = 1 lines. Here, the amount of scrolling is shown based on the number of lines to be scrolled when the display data is character data and has a specific character size. The number of lines to be corrected is corrected.

  In FIG. 3, when the automatic scroll is executed, the scroll is accelerated from the region D0 toward the region D2, and the scroll is decelerated from the region D2 toward the region D4. The setting of the scroll amount is not limited, other settings may be set, the number of divisions of the area is not limited to 5, and the division may not be equally divided, and the scrolling speed may be increased. The size may be changed accordingly.

  Next, the operation of the first embodiment will be described with reference to the drawings. A case where the scroll process is executed in the state of FIG. 3 will be described as an example. In FIG. 3, the scroll is assumed to be only in the vertical direction and not in the horizontal direction, but of course, it can also be applied to the horizontal scroll, and can be applied to the upward scroll.

  In the state of FIG. 3, the scroll direction instruction is downward, the display start position is not in the beginning of the content but in the middle, and the size at which the content can be displayed on the display unit 12 at the same time is shown as a display area. The display required amount (BH) is sufficiently large with respect to the display area height H which is the size of the display area, and the user needs a lot of scrolling to browse to the end of the content. The display area height H is determined by the display capability such as the size and resolution of the display unit 12.

  At the start of scrolling, the content, the display start position S, and the content end B are set as the display data information 17, but the scroll information is not set. An operation when the user performs a scroll operation in the downward direction in this state will be described. In the following description, a case where the user operates the key input unit 11 will be described. However, a scroll operation may be performed by using a position input device such as a mouse or an alternative device.

  FIG. 4 is a flowchart showing the operation of the first embodiment. This will be described below with reference to FIG. First, when the user presses the downward scroll key of the key input unit 11, the key input unit 11 detects the pressing of the scroll key and notifies the key event processing unit 13 of the detection. When the key event processing unit 13 receives a notification from the key input unit 11 that the scroll key is pressed, the key event processing unit 13 notifies the scroll processing unit 16 of the key pressing event together with information on the scroll direction.

  FIG. 4 is a flowchart showing the subsequent operation, and the operation of FIG. 4 shows the contents executed by the scroll processing unit 16. Referring to FIG. 4, upon receiving a key press event (S51), the scroll processing unit 16 acquires scroll direction information from the key event processing unit 13 (S52), and determines whether there is room for scrolling (S53). If there is no room for scrolling, the scroll processing unit 16 ends the process without scrolling.

  The scroll processing unit 16 determines the room for scrolling based on the content end B, the display start position S, and the display area height H because the scroll direction is downward. The scroll processing unit 16 determines that there is no room for crawl if the display start position S is already displaying the last part (S = B−H), and if S> (B−H). Judge that there is still room for scrolling. If the scroll direction is upward, the scroll processing unit 16 determines that there is room if the display start position S is not at the content head T.

  If there is room for scrolling, the scroll processing unit 16 activates a start timer for the timer event processing unit 14 (S54). Upon receiving the start timer, the timer event processing unit 14 starts counting of timer notifications at regular intervals from the OS, and the count value is a predetermined value that is determined in advance (which is sufficiently larger than the constant interval of timer notifications, for example, 1 second). Then, a timer event is notified to the scroll processing unit 16.

  Next, the scroll processing unit 16 divides the area in the scroll direction and sets the scroll amount for each divided area (S55). An area between the display start position S and “BH” obtained by subtracting the display area height H for one screen display from the last content B is the area to be divided. That is, the scroll processing unit 16 divides an area having a size of “BHS” starting from the position S.

  FIG. 3 is a diagram showing an example of division. The scroll processing unit 16 equally divides the division target area into five areas D0 to D4 in order from the display start position, and sets the scroll amount of the areas D0 to D4 to 1. 2, 4, 2, 1 are assigned. In FIG. 3, the area to be divided (BHS) is sufficiently large, and the scroll processing unit 16 can be divided into five. However, the scroll processing unit 16 reduces the number of divisions when the area to be divided is not sufficiently large. Or, if there are only a few lines, it may not be divided.

  Next, the scroll processing unit 16 executes scrolling at the set scroll speed, that is, the scroll amount (corresponding to the scroll speed) (S56). Since the first scroll is the area D0, the scroll processing unit 16 scrolls one line. After the scroll execution, the scroll processing unit 16 updates the display start position (S57). In this case, the scroll processing unit 16 moves the display start position S downward by one line to update from “a0” to “a0 + 1”, and prepares to execute the next scroll from the position (a0 + 1) lower by one line. .

  When the scroll processing unit 16 performs display after scrolling, the display processing unit 15 is notified of the address on the storage unit of the display start position S (a0 + 1) after scrolling, and the ideographic processing unit 15 displays in the storage unit. The amount of data that can be displayed in the display area is acquired from the data information 17 and the display unit 12 is instructed, and the display unit 12 displays the scrolled data.

  Although the operation of the key press event is completed as described above, the timer event processing unit 14 continues counting because the start timer is started in step S54. The subsequent processing is divided depending on the user's operation. When the user keeps pressing the scroll key for a predetermined time or more, the start timer reaches the predetermined time, and the timer event processing unit 14 notifies the scroll processing unit 16 of the timer event. When the user releases the scroll key, the key event processing unit 13 detects the release of the scroll key and notifies the scroll processing unit 16 of the key release event.

  Next, an operation when a timer event occurs will be described. When receiving the notification of the timer event (S61), the scroll processing unit 16 checks the state of the automatic scroll flag (S62). The automatic scroll flag is controlled to be in an on state when in an automatic scroll execution state and in an off state when not in an automatic scroll execution state.

  Since the automatic scroll flag is off when the first timer event occurs, the scroll processing unit 16 turns on the automatic scroll flag (S63). Since the automatic scroll flag is in the on state when the next timer event occurs, step S63 is omitted.

  Next, the scroll processing unit 16 compares the display start position with the end of the content to determine whether there is room for scrolling (S64). If there is room for scrolling, the interval timer is started (S65), and the steps already described Steps S56 and S57 are executed, a scroll operation is executed, the display start position is updated, and the timer event operation is ended. If there is no room for scrolling, the scrolling is not executed and the operation is terminated.

  The scroll executed at this time is determined by the scroll amount specified in the area to which the display start position belongs. Which area the display start position belongs to can be determined by comparing the display start position S with the positions a0 to a4 of each area (D0 to D5). The scroll processing unit 16 can extract the scroll information from the display data information 17 and compare the position information a0 to a4 of the scroll information with the display start position S to determine which area the display start position S belongs to. The scroll amount is taken out and used as the scroll amount to be executed. For example, if a1 ≦ S <a2, it is found that the display start position is in the region D1, the scroll amount is n1, and the scroll amount is 2 in FIG.

  At the time of the first timer event, if the display start position is within the area D0, the scroll processing unit 16 moves further down one line (a0 + 2) from the position (a0 + 1) scrolled down by one line by the key press event operation. Scroll like so. However, if the size of the area D0 is only one line, the display start position has moved to the area D1, so the scroll processing unit 16 starts from the position (a1 = a0 + 1) scrolled downward by one line by the key press event operation. Scroll to move further down one line (a2 = a0 + 2).

  When the timer event processing unit 14 receives the activation of the interval timer from the scroll processing unit 16, the timer event processing unit 14 starts counting of timer notifications performed at regular intervals from the OS, and the count value is set to a predetermined value (from a predetermined interval of timer notifications). When the time is sufficiently large (for example, 0.5 seconds), a timer event is notified to the scroll processing unit 16. In addition, although it does not specifically limit about the value of predetermined time, It sets in the suitable range with respect to the time which a user takes for the act of seeing the display part 10. FIG. Normally, the interval timer method is set shorter than the start timer, but the method is not limited.

  Thereafter, when the user continues to press the scroll key even after the timer event is generated by the start timer, the timer event is generated by the interval timer. The operation of the timer event by the interval timer operates similarly to the timer event by the start timer. However, since the automatic scroll flag is already on, step S63 is skipped. If there is room for scrolling, steps S56 and S57 are executed, scrolling is executed again according to the scroll amount of the region to which the display start position belongs, the display start position is updated, and the timer event operation is terminated.

  Since the interval timer is started again at step S65, if the user continues to press the scroll key after that, the timer event by the interval timer is repeated. If the user continues to hold down the scroll key, the scrolling proceeds to the end of the content and there is no room for scrolling, and the scrolling ends.

  Next, the operation when a key release event occurs will be described. When the user releases the scroll key, the key event processing unit 13 detects the release of the scroll key and notifies the scroll processing unit 16 of the key release event. When the scroll processing unit 16 detects a key release event (S71), it checks the state of the automatic scroll flag (S72).

  If the automatic scroll flag is on, the automatic scroll flag is turned off (S73), the interval timer is stopped (S74), and the start timer is also stopped (S75). That is, when the automatic scroll state is already in effect and the interval timer is operating, the automatic scroll flag is turned off and the interval timer is stopped to cancel the automatic scroll state.

  If the automatic scroll flag is off, the interval timer is not started yet, so only the start timer is stopped (S75). That is, if it is not yet in the automatic scroll state, the start timer is stopped to prevent the timer event from being generated by the start timer, and the transition to the automatic scroll state is suppressed.

  In this way, if the scroll key is released before entering the automatic scroll state, the scroll is executed only once and finished, and if the scroll key is released after the automatic scroll state has already been reached, the scroll is executed up to that point. Scrolling ends.

  Since the scroll speed is determined according to the scroll amount of the area to which the display start position belongs, the scroll speed is executed at a multi-stage speed. In the case of setting as shown in FIG. 3, the scroll speed is initially scrolled in units of one line, and the scroll speed is accelerated in units of two lines and in units of four lines as the scroll progresses. When scrolling further progresses, the scroll speed is reduced from 4 lines to 2 lines and 1 line.

  Therefore, the user can detect whether the current display position is the first part, the last part, or the middle part by changing the scroll speed. Further, since the last part is decelerated, the user can easily see the information before the last part. The scroll speed in FIG. 3 is set so as to accelerate sequentially to the middle and gradually decelerate from the middle. However, the area D0 to D3 may be accelerated and decelerated abruptly in the area D4. It may be increased to accelerate / decelerate more smoothly.

  In the above description, the region is equally divided, but the size of the region may be divided into a size proportional to the scrolling speed so that the scrolling speed may be changed at equal intervals. D2 may be made relatively large to shorten the scroll time to the end.

  As described above, since the present invention divides the area in the scroll direction when scrolling is started and sets a predetermined scroll speed for each area, by operating the area dividing method and the scroll speed setting method, Acceleration / deceleration patterns with various scroll speeds can be easily realized.

  Next, a second embodiment of the present invention will be described with reference to the drawings. In the second embodiment, not only the scrolling is started by the user's scroll operation as in the first embodiment, but also the scrolling is started to display the search keyword by searching for the keyword on the content. It is different in point.

  Therefore, the mobile phone 20 of the second embodiment shown in FIG. 5 has a configuration in which the keyword search processing unit 29 is added to the mobile phone 10 of the first embodiment. It goes without saying that the present invention can also be applied to electronic devices other than mobile phones in the second embodiment. Further, components having the same functions as those in the first embodiment are denoted by the same reference numerals as those in FIG. Unlike the operation of the scroll processing unit 16, the scroll processing unit 26 is different in that an operation for processing a search event is added, but the contents will be described in the following description of the operation.

  The display data information 27 is different in that “KS” is used instead of “BS” as a necessary display amount. Here, “K” is information indicating the position in the content including the search target keyword given from the search processing unit 29. In the second embodiment, scrolling is automatically executed to the position K and stopped. And when it stops, the search target keyword will be displayed.

  There are two scroll stop conditions: the first embodiment reaches the end of the content, or the user releases the scroll key during scrolling. In the second embodiment, the scroll stop condition is specified in advance. It becomes a stop position (a position with a search keyword) and does not stop halfway. Therefore, the second embodiment can be considered as an operation in which the scroll stop position of the first embodiment is changed from the last to the keyword position.

  The keyword search processing unit 29 operates when the user instructs a search operation for keywords or the like with respect to the content of the display data information 27 and searches for the corresponding keyword on the content. If the keyword exists in the content as a result of the search, the keyword search processing unit 29 notifies the scroll processing unit 26 of a search event including the keyword position in order to display the keyword position as a search result.

  Next, the operation of the second exemplary embodiment of the present invention will be described with reference to the drawings. FIG. 6 is a flowchart showing the operation of the second embodiment. However, since the operation related to the key press / release event has been described in the first embodiment, the description related to the operation is omitted.

  First, when there is a search event notification from the keyword search processing unit 29 (S81), the scroll processing unit 26 acquires the searched keyword position (S82). Subsequently, the scroll processing unit 26 determines whether or not the acquired keyword position is included in the display range of the current display start position (S83). That is, it is determined whether the keyword searched at the present time is displayed. The scroll processing unit 26 determines in step S83 depending on whether the keyword position K satisfies the condition “S ≦ K ≦ S + H”. If the keyword position is already within the display range, the scroll processing unit 26 ends the process and does not execute scrolling.

  When the keyword position is not within the display area, the scroll processing unit 26 divides the area between the display start position S and the keyword position K into a plurality of areas by a predetermined method and sets the scroll speed for each divided area. Set (S84). The display start position S when scrolling is stopped is “K” if the keyword is displayed at the top of the display area, and is “KH” if the keyword is displayed at the bottom of the display area. However, where to display the keyword in the display area may be arbitrarily selected.

  FIG. 7 is a diagram illustrating an example of division and scroll speed setting according to the second embodiment. In the example shown in FIG. 7, the keyword position K is at the top with respect to the display start position S, and the area “KS” is to be divided. In FIG. 7, the division target area is divided into three areas D0 to D2. The scroll amount is set to be sequentially “4, 2, 1” with respect to the areas D0 to D2, and the size of the areas D0 to D2 is set to be “4: 2: 1” and proportional to the scroll amount. ing. Accordingly, the scroll times of the areas D0 to D2 are substantially the same. Note that if the area to be divided is not sufficiently large, the scroll processing unit 26 may reduce the number of divisions from a predetermined number or not perform division.

  Next, the scroll processing unit 26 activates an interval timer for the timer event processing unit 14 (S85). When activated, the timer event processing unit 14 operates an interval timer, counts the timer notification of the OS, and notifies the scroll processing unit 26 of the timer event when a predetermined time is reached. The operation of the timer event processing unit 14 is the same as that in the first embodiment.

  Next, the scroll processing unit 26 executes scrolling according to the scroll amount of the area to which the display start position S belongs (S86), and updates the display start position (S87). In the case of FIG. 7, since the display start position S is initially in the area D0, it is scrolled by four lines, and the display start position is updated from “a0” to “a0 + 4”.

  Next, when the timer event processing unit 14 notifies the scroll processing unit 26 of the timer event by the operation of the interval timer, the scroll processing unit 26 detects the timer event (S91) and is within the display range of the current display start position S. It is determined whether the acquired keyword position K is included in (up to S + H) (S92). If a keyword is already included in the display range, the scroll processing unit 16 ends the process and does not execute scrolling.

  If the display position keyword position K is not included, the scroll processing unit 26 activates the interval timer again (S93), and then executes scrolling according to the scroll amount of the area to which the display start position S belongs (S86). The display start position is updated (S87).

The timer event by the interval timer is repeated and stopped until the keyword position enters the display area. In the case of FIG. 7, the scrolling by the timer event is repeated, and the display start position S moves to the areas D0 to D2. At this time, the scroll speed gradually decreases as the keyword position is approached. Therefore, although it is difficult for the user to read the content details at the start of scrolling, it becomes easier to read the content details near the keyword position. The user can detect that the keyword position is approaching due to the change in scrolling speed,
This makes it easier to check the content of the part in front of the keyword.

  Although the operation when the key pressing / release event is also processed in the second embodiment is not shown, control is provided by providing a flag indicating whether the scroll processing unit 26 is scrolling by key pressing or searching. When the timer event occurs, it can be easily realized if the processing is divided into the processing of FIG. 4 or the processing of FIG. 6 according to the state of this flag.

  In the second embodiment, an example of dividing into three regions has been shown. However, as in the first embodiment, it is divided into five equal parts, the scroll amount is set to be the same, and acceleration is initially performed toward the search keyword position. However, it may be set to decelerate toward the end. Conversely, the division and scroll amount of the first embodiment may be the same as those of the second embodiment. Of course, according to the user's request, divisions other than those in the first embodiment and the second embodiment and the setting of the scroll speed may be set, and the present invention can easily cope with this.

  In the embodiment, a mobile phone has been described as an example of an electronic device. However, as already described, the present invention can also be used in portable information devices other than mobile phones, and information processing devices such as personal computers and server devices. . The present invention can also be applied to other electronic devices as long as the display data is scroll-displayed by an electronic device having a configuration required by the present invention.
