Description

  The present invention relates to a display control device, an electronic apparatus, a display control method, and a program for displaying a part of display contents in an enlarged state.

  For example, various visible information such as character strings, graphics, and images can be displayed on a display screen provided in an electronic device such as a mobile phone terminal. It is also possible to access a portal site on the Internet and display information (content) acquired from the portal site as visible information on a display screen.

  However, if a lot of information is registered in one page of the portal site, the characters displayed on the terminal display screen will be very small, or only a small part of one page will be displayed. Sometimes it cannot be displayed on the screen. In particular, when the content of a portal site created in accordance with the display capability of a general computer terminal is to be viewed using a mobile phone terminal, the size of the display screen is small or the display capability (relative display capability ( For example, a display screen with a low resolution or the like is used, so that the displayed characters are often small and difficult to read. In addition, if the display content on the screen is small, not only is it difficult to read the content, but it also becomes difficult to position the cursor etc. when clicking on a desired location on the display, and the desired position cannot be clicked There is also.

  As a display control method for such a conventional display device, a touch panel is arranged on the display screen of the mobile terminal device, and a specific instruction from the user regarding the length of time when the user presses the touch panel and the difference in pressing force. It is proposed that the operation of enlarging / reducing the display content of a specific area is performed according to this instruction (see, for example, Patent Document 1).

  In addition, an enlarged display window is generated in response to the start of processing, and the display contents of a predetermined area are enlarged and displayed in the enlarged display window, the area is moved as the mouse moves, and the area size is changed. Or changing the enlargement ratio (for example, see Patent Document 2).

  In addition, the purpose is to provide an enlargement function suitable for a touch panel environment on a web browser, and in the case of enlargement display, it has been proposed to divide the display screen to provide an enlargement area and a normal area (for example, And Patent Document 3).

  In addition, a first window and a second window displayed on the first window are provided, and when the cursor indicating the input position on the first window approaches a predetermined distance from the position of the second window. It has been proposed to automatically move the display position of the second window in the other direction (see, for example, Patent Document 4).

  In addition, the operating system (for example, Windows: registered trademark), which is basic software that is standardly used in current personal computers, has contents of a part of the window on the display screen (in the vicinity of the display position of the mouse cursor). It has a magnifying glass function to display it at a specific other location in an enlarged state. In this function, the area for displaying the enlarged information is fixed at a specific position.

JP 2005-182367 A JP 2003-50653 A JP 2005-56286 A JP 2000-20207 A

  In various electronic devices, a touch panel is arranged on a display screen, and an input operation is made possible by touching the display screen with a human finger or a stylus pen (pen with a sharp tip). In particular, when performing an input operation on a relatively small device such as a mobile phone terminal, there are large restrictions on the number and size of buttons that can be operated, but operability is improved by using a touch panel. Is possible.

  However, when an input operation is performed using a touch panel, there are circumstances specific to the touch panel regarding the input operation. For example, when the user tries to press a certain area on the touch panel with a finger, the pressed finger itself overlaps with a part of the display screen, and the display content of the part becomes invisible to the user's eyes. Makes it difficult to align the finger with the target area.

  In addition, when using the function of enlarging and displaying the display content of the first area designated by the user on the display screen to another second area, a part of the display content on the screen is displayed for enlargement display. Since it may be hidden by the second area, the location that the user wants to see is hidden by the second area unless the position for arranging the second area is adjusted well. For example, even when the technique of Patent Document 4 is adopted, the second area does not move unless the cursor is brought close to the second area, so that the portion that the user wants to see is the second area for enlarged display. It is inevitable to hide by. This is particularly noticeable in the case of a small electronic device such as a mobile phone terminal having a small display screen.

  The present invention has been made in view of the above circumstances, and when the contents of a desired area on the display screen are enlarged and displayed in another place, the operability relating to the input operation of the user and the reading of the display contents. It is an object of the present invention to provide a display control device, an electronic device, a display control method, and a program capable of improving the above.

  In order to achieve the above object, a first display control device of the present invention includes a position detection unit that detects an input position in a display screen on which information is displayed, and movement of the position detected by the position detection unit. An enlarged image obtained by enlarging the image of the first area including the position detected by the coordinate movement detection unit to be detected and the position detection unit at a predetermined magnification is set to a second area other than the first area on the display screen. An enlarged display information generating unit that generates enlarged display information for display in an area, and the enlarged display information generating unit, when a movement of a position is detected by the coordinate movement detecting unit, The configuration is changed.

  According to this configuration, the positional relationship between the first area (for example, the enlargement target area) and the second area (for example, the enlarged display area) can be automatically controlled. Even if there is, the second area is arranged in the vicinity of the position of the first area, which is the part to be enlarged, and the user can quickly grasp the place to be seen and its contents (enlarged display information). Operability is improved.

  Further, the second display control device of the present invention has a display unit that displays a display screen including the image of the first area and the enlarged image of the second area based on the enlarged display information. Yes.

  According to this configuration, by displaying on the display unit based on the display information (enlarged display information), the contents of the desired area on the display screen can be actually enlarged and displayed in another place, and the user It is possible to improve the operability related to the input operation and reading of the display contents.

  Moreover, the 3rd display control apparatus of this invention is set as the structure which has an expansion object information generation part which produces | generates the expansion object information containing the outline information for displaying the outline of said 1st area | region so that visual recognition is possible.

  According to this configuration, the user can easily grasp the range of the portion to be enlarged in the display screen by looking at the contour information displayed as visible information. The outline information may be, for example, a figure corresponding to the outline surrounding the entire range (transparent inside), or the entire area may be displayed in black and white with the gray level of the visible information contained therein, or the entire area. May be realized by switching the display color in the color to a color different from the surrounding color.

  In the fourth display control device of the present invention, when the enlarged display information generation unit detects the movement of the position by the coordinate movement detection unit, the first display control device generates the first display based on the position information of the first region. The position information of the second area is changed so that the second area does not overlap with the second area, and enlarged display information including the changed position information of the second area is generated.

  According to this configuration, even when the first area (for example, the enlargement target area) is moved, the range of the first area after the movement and the range of the second area (for example, the enlarged display area) are automatically overlapped. Therefore, the user can always check the entire first area and the entire second area. There is no need for the user to perform a special operation to prevent the overlap.

  In the fifth display control device of the present invention, when the movement of the position is detected by the coordinate movement detection unit, the first area is reduced so as to reduce the first area based on the speed or acceleration of the movement. The configuration information includes an enlargement target information generation unit that changes the shape information of the first region and generates enlargement target information including the changed shape information of the first region.

  According to this structure, the operativity at the time of moving a 1st area | region (for example, expansion object area | region) can be improved. That is, it is possible to prevent overlap between the first area and the second area (for example, an enlarged display area) by reducing the size of the first area when moving. Further, when the first area is reduced, the amount of data to be processed is reduced, so that the addition of processing is reduced and high-speed processing is possible. Note that it is preferable to temporarily reduce the size of the second region in accordance with the size of the first region.

  In the sixth display control device of the present invention, when the enlarged display information generation unit detects the movement of the position by the coordinate movement detection unit, the second area is based on the speed or acceleration of the movement. The shape information of the second region is changed so as to be reduced, and the shape is changed so as to decrease the predetermined magnification based on the speed or acceleration of the movement. Enlarged display information including the information and the magnification is generated.

  According to this structure, the operativity at the time of moving a 1st area | region (for example, expansion object area | region) can be improved. That is, by reducing the size and magnification of the second area (for example, the enlarged display area) during movement, the same content as the entire visible information displayed in the first area is displayed in the second area. Therefore, for example, even when a part of the first area is hidden by a finger pressing the touch panel on the screen, the user can also display the contents of the hidden part by the contents displayed in the second area. Since it can confirm, the area | region can be moved, confirming the visible information of the whole location of expansion object.

  In the seventh display control device of the present invention, the enlarged display information generation unit hides the image of the second region while the movement of the position is detected by the coordinate movement detection unit. The enlarged display information including the non-display information is generated.

  According to this structure, the operativity at the time of moving a 1st area | region (for example, expansion object area | region) can be improved. That is, since the display related to the second area (for example, the enlarged display area) is temporarily deleted during the movement, the display content (visible information before enlargement) of the first area is displayed below the display of the second area. It is possible to prevent hiding, and the user can move the first region while confirming the entire visible information of the movement destination.

  Further, an eighth display control device of the present invention has a storage unit for storing handedness information of a user who uses the display unit for displaying the display screen, and the enlarged display information generation unit includes the handedness information. Based on this, the enlarged display information is generated.

  According to this structure, the operativity at the time of moving a 1st area | region (for example, expansion object area | region) can be improved. For example, when the user performs an input operation by pressing the touch panel on the screen with a finger, a part of the display screen is hidden by the finger or hand and is not visible to the user's eyes. Therefore, a part of the first area or the second area (for example, the enlarged display area) may be hidden during the input operation. On the other hand, the positional relationship (the hidden part on the screen) between the display screen and the hand operating it varies greatly depending on whether the user operates using the right hand or the left hand. Therefore, whether the user is highly likely to operate using the right hand as in the case of right-handed or whether the user is likely to operate using the left hand as in the case of left-handed is distinguished and stored as handedness information in advance. Keep it. Then, by determining the position where the second area is arranged using this dominant hand information, it is possible to prevent the display content of the second area from being hidden by a hand or a finger.

  In the ninth display control device of the present invention, when the enlarged display information generation unit includes the first area in the third area on the display screen, the display area other than the third area on the display screen. The enlarged display information including arrangement information for preferentially arranging the second area in the area is generated.

  According to this configuration, the second area (for example, the enlarged display area) can be positioned at a more appropriate position, and it is possible to prevent the original necessary information before enlargement from becoming invisible due to the display of the second area. For example, when one page of content to be displayed on the display screen is divided into a plurality of frames, target information such as text is arranged in the first frame, and additional information such as advertisement is arranged in the second frame The second region may be positioned in the second frame. Thereby, since the second area is not arranged in the first frame, the user can always see the entire first frame.

  In the tenth display control device of the present invention, the enlarged display information generation unit preferentially arranges the second area in an area with a small amount of information per unit area on the display screen. The enlarged display information including is generated.

  According to this configuration, the second area (for example, the enlarged display area) can be positioned at a more appropriate position, and it is possible to prevent the original necessary information before enlargement from becoming invisible due to the display of the second area. For example, when displaying map content, the visible information that is displayed includes areas that contain almost no information that changes over a large area, such as the ocean, or areas that are small, such as urban areas. There are areas that contain a large amount of information. Moreover, even if the display of a portion with a small amount of information such as the sea is hidden, there is little possibility that it will be a hindrance when the user confirms the content. Therefore, for example, the second region may be preferentially arranged at a location with a small amount of information such as the sea. Further, in the compressed content information, a portion with a small amount of information such as the sea has a high compression rate. Therefore, control may be performed so that the priority is determined based on the compression rate.

  In the eleventh display control apparatus of the present invention, the enlarged display information generation unit is configured such that the position detected by the position detection unit is within the second region, and the position movement is detected by the coordinate movement detection unit. When the distance between the contour of the second area and the moved position is less than a predetermined value, the shape information of the second area is changed to enlarge the second area. In addition, enlarged display information including the changed shape information of the second region is generated.

  According to this configuration, user operability can be improved. For example, although it is possible to automatically determine the size and position of the second area (for example, the enlarged display area) for enlarged display, the entire area that the user wants to see does not fit into the second area. There may be no. Therefore, an operation in which the user's input position protrudes from the second area is regarded as detection of an instruction for changing the size or the like, and the size of the second area is enlarged. As a result, the user can enlarge the second area to a desired size, and can confirm the entire necessary information in the enlarged second area. Further, it is not necessary to operate the first area (for example, the enlargement target area) in order to change the size of the second area while operating the second area.

  The twelfth display control apparatus according to the present invention is the image of the first region when the enlarged display information generation unit includes a plurality of images of the same content as images displayed on the display screen. The enlarged display information for displaying the image of the same content different from the image displayed as the enlarged image of the second area is generated.

  According to this configuration, user operability can be improved. For example, simply enlarging and displaying an image or the like does not increase the amount of information that can be confirmed, although it is easy for the user to see. On the other hand, assuming content of a map or a train route map, for example, a plurality of pieces of data having different scales are prepared in advance as one content, and the amount of available information may be different for each scale. . Therefore, for the information to be enlarged and displayed in the second area, other data having a different scale from that of the other area is used. Thereby, information which can be read by more users in the second area can be displayed.

  Further, in the thirteenth display control device of the present invention, when the selectable information is included in the first area, the enlarged display information generating unit sets an identifier of the selectable information in the second area. The enlarged display information including the identifier information for display is generated.

  According to this configuration, user operability can be improved. For example, since many pages of link information that can be operated (clicked) are included in the page of the portal site, the enlarged second area (for example, the page of the portal site displayed on the screen (for example, It is also possible for the user to perform a selection operation such as clicking on the contents of the (enlarged display area). However, the size and position of the first area to be enlarged (for example, the area to be enlarged) and the second area for displaying the enlarged information do not always exactly match the user's wishes. Since it is not always possible to accurately press the coordinates of a desired location in the displayed visible information, the input operation may be time-consuming. Therefore, elements of candidate information (for example, a character string for each link) that can be selected like link information are individually extracted from the information to be expanded (the content of the first information included in the first region), and this Candidate information is displayed in the second area in a selectable state. As a result, it is possible to eliminate the display of extra information that cannot be selected or to display the entire partially missing information in the second area, or by inputting from a button such as a number instead of inputting coordinates. It is also possible to select candidate information, which improves operability.

  The fourteenth display control device of the present invention displays a display screen including an image of the first area and an enlarged image of the second area based on the enlarged display information and the enlargement target information. It is set as the structure which has a part.

  According to this configuration, the content of the desired area on the display screen is actually enlarged and displayed in another place by displaying on the display unit based on the display information (enlarged display information and enlargement target information). It is possible to improve operability related to user input operations and reading of display contents.

  According to the first display control method of the present invention, in the display control device, a position detection step for detecting an input position in a display screen on which information is displayed, and a movement of the position detected in the position detection step are detected. And an enlarged image obtained by enlarging the image of the first area including the position detected in the position detecting step with a predetermined magnification in a second area other than the first area on the display screen. The method includes a step of generating enlarged display information for display and a step of changing the enlarged display information when a movement of a position is detected in the movement detecting step.

  According to this configuration, the positional relationship between the first area (for example, the enlargement target area) and the second area (for example, the enlarged display area) can be automatically controlled. Even if there is, the second area is arranged in the vicinity of the position of the first area, which is the part to be enlarged, and the user can quickly grasp the place to be seen and its contents (enlarged display information). Operability is improved.

  The first program of the present invention is a program for causing a computer to execute each step of the display control method.

  According to this program, the positional relationship between the first area (for example, the enlargement target area) and the second area (for example, the enlarged display area) can be automatically controlled. Even if there is, the second area is arranged in the vicinity of the position of the first area, which is the part to be enlarged, and the user can quickly grasp the place to be seen and its contents (enlarged display information). Operability is improved.

  The first electronic device of the present invention includes an image acquisition unit that communicates with an external device to acquire image data, a storage unit that stores the image data, and any one of the display control devices described above. It has a configuration.

  According to this configuration, for example, for the acquired image data, the positional relationship between the first area (for example, the enlargement target area) and the second area (for example, the enlarged display area) can be automatically controlled. Regardless of where you want to see, the second area will be placed near the position of the first area, which is the part to be enlarged, and the user wants to see the contents and their contents (enlarged display information ) Can be quickly grasped, and the operability is improved.

  According to the present invention, it is possible to improve operability related to user input operations and reading of display contents. For example, since the positional relationship between the first area to be enlarged and the second area in which the enlarged information is displayed can be automatically controlled in the original display content, the user can see which part on the display screen. Even if it is desired, the second area will be arranged near the position of the first area, and the user can quickly grasp the location to be seen and its contents (enlarged display information), Operability is improved.

  In step S14, the enlarged display input support unit 20 stores the fact that the state of the enlarged display area 102 has been switched to “displaying”, so that it corresponds to the corresponding parameter (“display” of the element in FIG. 8C). ) Is changed to “Displaying”. Then, the process proceeds to step S15.

  In step S <b> 15, the enlarged display input support unit 20 detects the coordinates of the position pressed by the user on the screen by the input coordinate detection unit 21, and compares the coordinates with the range of the enlarged display region 102. If the coordinate of the position pressed by the user is inside the range of the enlarged display area 102, the process proceeds to step S16, and if it is outside, the process proceeds to step S17.

  In step S <b> 16, the enlarged display input support unit 20 converts the coordinates in the enlarged display area 102 to the coordinates in the original area (portion surrounded by the enlargement target frame 101) corresponding to this area. Then, the process proceeds to step S19.

  In step S <b> 17, the enlarged display input support unit 20 identifies whether the coordinate movement detection unit 22 has detected the movement (drag operation) of the user input position. If the movement is detected, the process proceeds to step S18. If the input position does not change, the input unit 11 detects that the finger 103 has left the touch panel in step S21, and then proceeds to step S23. Note that the separation of the finger 103 from the touch panel can be detected by, for example, detecting no pressure on the display screen using a pressure sensor.

  In step S <b> 18, the enlarged display input support unit 20 performs a process (enlarged screen movement control process) for moving the enlarged display area 102 by the enlarged screen movement control unit 26. Details of this processing will be described later. After that, it is detected in step S21 by the input unit 11 that the finger 103 has left the touch panel, and then the process proceeds to step S23.

  In step S19, the enlarged display input support unit 20 identifies whether or not the coordinate movement detection unit 22 has detected the movement (drag operation) of the user's input position. If movement is detected, the process proceeds to step S20. If there is no change in the input position, it is detected in step S21 that the finger 103 has left the touch panel, and then the process proceeds to step S22.

  In step S <b> 20, the enlarged display input support unit 20 performs a process (enlarged screen resize control process) for changing the size of the enlarged display area 102 by the enlarged screen resize control unit 25. Details of this processing will be described later. After that, it is detected in step S21 by the input unit 11 that the finger 103 has left the touch panel, and then the process proceeds to step S23.

  In step S22, the input unit 11 and the enlarged display input support unit 20 perform a process for an input operation (touch panel tapping) from the user. That is, when the user presses a position (P2: not shown) inside the enlarged display area 102 and then performs a tapping operation, the position coordinates (in the enlargement target frame 101 corresponding to the input position (P2)) ( (P1: not shown) is obtained in step S16, so that an input operation is performed on the position coordinate (P1) by the input unit 11 (for example, a certain element being displayed is clicked) Appropriate processing is performed. Then, the process proceeds to step S23.

  In step S <b> 23, the enlarged display input support unit 20 performs a process (enlarged screen non-display control process) for hiding the enlarged display region 102 by the enlarged screen non-display control unit 24. Details of this processing will be described later.

  After the process of step S23 is completed, the cellular phone terminal 1 ends the process of FIG. 2 and waits for the next input operation.

  According to the cellular phone terminal 1 that performs the processing of FIG. 2, the contents of a desired area (for example, in the enlargement target frame 101) on the display screen 100 are enlarged and displayed in another place (for example, the enlarged display area 102). In this case, it is possible to improve the operability related to the user's input operation and display content reading.

  Next, an example of detailed operation of the mobile phone terminal 1 in the enlarged screen display control process will be described. FIG. 3 is a flowchart showing an example of detailed operation of the cellular phone terminal 1 in the enlarged screen display control process.

  If an input by the user's instruction (pressing the touch panel) is detected in a state where an enlarged screen (for example, corresponding to the enlarged display area 102 shown in FIG. 10) is not displayed on the display screen, the enlarged screen display control process is performed. Be started.

  First, in step S31, the input coordinate detection unit 21 acquires the coordinates (x, y: this is the display position (x, y) of the enlargement target frame 101) of the position input by the user pressing the touch panel, The enlarged screen display control unit 23 acquires the contents (stored information) of various parameters shown in FIG. Then, the process proceeds to step S32.

  If the processing of FIG. 3 can be performed, some of the parameters shown in FIG. 8 may be acquired.

  In step S32, whether the function related to “dominant hand” (the content of “dominant hand setting” in FIG. 8A) is turned on (yes) in the parameters acquired in step S31. If it is on, the process proceeds to step S33, and if it is off (no), the process proceeds to step S34.

In step S33, the enlarged screen display control unit 23 determines parameters of coordinates for displaying the enlarged display area 102 (X and Y of “display coordinates” shown in FIG. 8C) as follows. Note that the content determined by the user in advance is stored for information indicating whether the subject is right-handed or left-handed (the content of “handedness” shown in FIG. 8D).
Right-handed: X ← x−α
Left-handed: X ← x + α
When y belongs to the upper half of the screen: Y ← y−β
When y belongs to the lower half of the screen: Y ← y + β
Then, the process proceeds to step S37.

  In step S34, the enlarged screen display control unit 23 turns on the parameter indicating the priority area designation function (corresponding to the content of “priority area setting” in FIG. 8A) among the parameters relating to the enlargement setting. Check whether it is. If this is on, the process proceeds to step S35, and if it is off, the process proceeds to step S36.

  In step S35, the enlarged screen display control unit 23 determines the parameter contents of the coordinates (X and Y of “display coordinates” shown in FIG. 8C) for displaying the enlarged display area 102 in advance. To be decided. That is, since the priority parameter determined for each area on the screen exists as the contents of the “screen area configuration” in FIG. 8D, the area number (AreaNo) selected in the order from the highest priority among them is displayed. ) Is determined as the display coordinates (X, Y) of the enlarged display area 102. Then, the process proceeds to step S37.

In step S36, the enlarged screen display control unit 23 determines parameters of coordinates for displaying the enlarged display area 102 (X and Y of “display coordinates” shown in FIG. 8C) as follows.
X ← x + α
Y ← y + β
Then, the process proceeds to step S37.

  In step S37, the entire display area of the enlarged display area 102 determined by the coordinates (X, Y) determined in any of steps S33, S35, and S36 by the enlarged screen display control unit 23 is the displayable range of the display screen. Whether or not it protrudes (for example, the range of the display screen 100 shown in FIG. 9) is checked. If it protrudes, the process proceeds to step S38, and if it does not protrude, the process proceeds to step S39.

  In step S38, the enlarged screen display control unit 23 determines at least one of X and Y of coordinates (X, Y) so that the entire display area of the enlarged display area 102 does not protrude from the displayable range of the screen. Change to a predetermined value (fixed value). Then, the process proceeds to step S39.

  In step S39, the function related to “enlargement setting application cooperation” (contents of “application cooperation enlargement” in FIG. 8A) is turned on (yes) in the parameters acquired in step S31 by the enlargement screen display control unit 23. If it is on, the process proceeds to step S40, and if it is off, the process proceeds to step S41.

  In step S40, the cellular phone terminal 1 performs an application cooperation enlarged display control process shown in FIG. That is, the application cooperation unit 28 requests information on the enlarged screen from the application program (application) being used, and creates unique enlarged screen information based on the information acquired from the application program. Then, the process proceeds to step S41.

  In step S41, the enlarged screen output unit 27 and the display unit 12 display, for example, a rectangular enlargement target frame 101 as shown in FIGS. 9 and 10 at a position centered on the coordinates (x, y) pressed by the user. To do. Further, for example, a rectangular enlarged display area 102 as shown in FIGS. 9 and 10 is displayed at a position centered on the coordinates (X, Y) determined by the above processing, and in the enlarged display area 102, For example, an enlarged image is visually displayed as shown in the display screen 100a of FIG. The enlarged image is a result of enlarging the visible information (image such as a character string) of the entire rectangular area included inside the enlargement target frame 101 according to the enlargement ratio R.

  According to the mobile phone terminal 1 that performs the processing of FIG. 3, it is possible to display an image to be enlarged and an enlarged image obtained by enlarging the image to be enlarged at different positions on the display screen 100. Furthermore, it is possible to perform display that is easier for the user to see in consideration of various parameters such as dominant hand setting and area setting.

  The reason why the enlargement target frame 101 is displayed is to allow the user to easily grasp the entire range of the rectangular area to be enlarged on the display screen. Specifically, the enlargement target frame 101 is composed of a combination of four line segments corresponding to the outline of a rectangle that encloses the entire rectangular area to be enlarged. Inside the rectangle, characters and the like to be enlarged can be seen. For example, it is transparent. Note that the enlargement target frame 101 may be replaced with another display form. For example, it may be possible to distinguish between the inside and the outside by reversing the gradation of the visible information contained in the entire rectangular area in black and white. Further, the display color of the visible information included in the entire rectangular area may be replaced with a different color so that the inside and the outside can be distinguished.

  Next, an example of detailed operation of the mobile phone terminal 1 in the enlarged screen movement control process will be described. FIG. 4 is a flowchart showing an example of detailed operation of the mobile phone terminal 1 in the enlarged screen movement control process.

  When it is detected that the user moves a finger on the screen (drag operation: drag) while pressing the touch panel at a position different from the inside of the enlarged display area 102, the enlarged screen movement control process is started.

  First, in step S51, the enlarged screen movement control unit 26 saves the contents of the size and magnification (screen sizes L and W, enlargement ratio R in FIG. 8C) that are parameters of the enlarged screen. Further, the enlarged screen movement control unit 26 acquires the contents (stored information) of various parameters shown in FIG. Then, the process proceeds to step S52.

  In step S52, the coordinate movement detection unit 22 detects a movement operation by detecting the movement (change) of the input coordinates. Then, the process proceeds to step S53.

  In step S53, the enlargement screen movement control unit 26 turns on the function related to “enlargement target frame size reduction” in the enlargement setting (the content of “enlargement target frame reduction” in the parameter shown in FIG. 8A). If it is on, the process proceeds to step S54, and if it is off, the process proceeds to step S55.

  In step S54, the enlarged screen movement control unit 26 detects the movement speed (movement distance per unit time) related to the change of the input position, and determines the size of the enlargement target frame 101 ("screen size" in FIG. 8B). (Corresponding to “l, w)” and a parameter for determining the size of the enlarged display area 102 (corresponding to “screen size” (L, W) in FIG. 8C) is reduced according to the moving speed. Note that the movement acceleration may be used instead of the movement speed. Then, the process proceeds to step S60.

  In step S55, the enlargement screen movement control unit 26 turns on the function relating to the “enlargement screen magnification reduction” of the enlargement setting (the content of the “enlargement screen magnification reduction” parameter shown in FIG. 8A). If it is on, the process proceeds to step S56, and if it is off, the process proceeds to step S57.

  In step S56, the enlarged screen movement control unit 26 detects the movement speed (movement distance per unit time) related to the change of the input position, and determines the magnification (magnification and size) of the enlarged display area 102 (see FIG. 8C). The enlargement ratio (R) and “screen size” (L, W) are reduced according to the moving speed. Note that the movement acceleration may be used instead of the movement speed. Then, the process proceeds to step S60.

  In step S57, whether or not the function related to “enlarged screen concealment” in the enlargement setting (the content of the “enlarged screen concealment” parameter shown in FIG. 8A) is turned on (yes). If it is on, the process proceeds to step S58, and if it is off, the process proceeds to step S60.

  In step S58, the enlarged screen movement control unit 26 temporarily erases (hides) the display related to the enlarged display area 102 displayed on the display screen. Then, the process proceeds to step S59.

  In step S <b> 59, the enlarged screen movement control unit 26 switches the parameter indicating the display state of the enlarged display area 102 (the content of “display” in FIG. 8C) to “hidden”. Then, the process proceeds to step S60.

  In step S60, the cellular phone terminal 1 executes the enlarged screen display control process already described in FIG. Then, the process proceeds to step S61.

  In step S61, the enlarged screen movement control unit 26 identifies whether or not the movement of the user input position for moving the enlargement target frame 101 and the enlarged display area 102 continues. Whether or not the movement is continued is determined by, for example, whether or not the movement of the input position is detected by the coordinate movement detection unit 22 in a predetermined period. If it continues, the process returns to step S52, and if the movement is completed, the process proceeds to step S62.

  In step S62, the enlarged screen movement control unit 26 returns the parameter indicating the display state of the enlarged display area 102 (the content of “display” in FIG. 8C) to “displaying”.

  According to the cellular phone terminal 1 that performs the processing of FIG. 4, an enlarged image obtained by enlarging an image to be enlarged and an image to be enlarged even when the area to be enlarged (for example, the enlargement target frame 101) is moved. Can be displayed at different positions on the display screen 100. For example, even if the enlargement target frame 101 and the enlargement target region 102 are overlapped only by moving the enlargement target region 102, the size of the enlargement target frame 101 or the enlargement target region 102 is reduced. By reducing the magnification of enlargement, it is possible to perform display that is easier for the user to see.

  Next, an example of a detailed operation of the cellular phone terminal 1 in the enlarged screen non-display control process will be described. FIG. 5 is a flowchart showing an example of detailed operation of the cellular phone terminal 1 in the enlarged screen non-display control process.

  First, in step S71, time measurement is started by a timer (not shown) provided in the mobile phone terminal 1. Then, the process proceeds to step S72.

  In step S72, the enlarged screen non-display control unit 24 determines whether or not an input by the input unit 11 is detected within a predetermined period from the start of time measurement by the timer. If an input is detected within the predetermined period, the process proceeds to step S73, and if not detected, the process of FIG.

  In step S <b> 73, when no input is detected within a predetermined period, the enlarged screen non-display control unit 24 erases the display by the enlarged display area 102. Then, the process proceeds to step S74.

  In step S74, the enlarged screen non-display control unit 24 switches the parameter indicating the display state of the enlarged display area 102 (the content of “display” in FIG. 8C) to “non-display”.

  According to the mobile phone terminal 1 that performs the processing of FIG. 5, when the screen operation by the user is finished, it is possible to eliminate the unnecessary screen by deleting the enlarged screen.

  Next, an example of a detailed operation of the mobile phone terminal 1 in the enlarged screen resize control process will be described. FIG. 6 is a flowchart showing an example of detailed operation of the mobile phone terminal 1 in the enlarged screen resize control process.

  When the input position of the user is inside the enlarged screen and the movement (drag operation) of the input position is detected, the enlarged screen resizing control process is started.

  First, in step S81, the enlarged screen resizing control unit 25 calculates the distance between the coordinates (point coordinates) of the latest position pressed by the user and each side of the rectangle of the displayed enlarged display area 102. Then, it is determined whether or not these distances are equal to or smaller than the parameter expansion threshold e (content of the parameter “expansion threshold” shown in FIG. 8C). If it is equal to or smaller than the enlargement threshold e, the process proceeds to step S82. If it is greater than the enlargement threshold e, the process in FIG. 6 ends.

  In step S82, the enlarged screen resizing control unit 25 enlarges the size of the enlarged display area 102 (corresponding to the parameter “screen size (L, W)” shown in FIG. 8C) as the input position is moved. .

  According to the mobile phone terminal 1 that performs the processing of FIG. 6, for example, when the distance between the pointed position and the enlargement target area 102 is less than a predetermined length, the enlargement target area 102 can be expanded, Since it is possible to read characters and the like without depending on the operation in the enlargement target frame 101, the convenience for the user is dramatically improved.

  Next, an example of detailed operation of the mobile phone terminal 1 in the application cooperation enlarged display control process will be described. FIG. 7 is a flowchart illustrating an example of detailed operation of the mobile phone terminal 1 in the application cooperation enlarged display control process.

  In the enlarged screen display control process described with reference to FIG. 3, the function relating to “enlargement setting application cooperation” (contents of “application cooperation enlargement” in FIG. 8A) is turned on (yes), and the application program Is being executed, the application cooperation enlarged display control process is started.

  First, in step S91, the application cooperation unit 28 requests the application unit 30 to generate an enlarged screen by the enlarged screen generation unit 31. Then, the process proceeds to step S92.

  In step S92, the application cooperation unit 28 acquires the enlarged screen generated by the enlarged screen generation unit 31 from the application unit 30, and sets the acquired enlarged screen as an enlarged screen unique to the application.

  According to the mobile phone terminal 1 that performs the processing of FIG. 7, it is possible to flexibly select and display the image of the enlargement target frame 101 and the image of the enlargement display area 102 in accordance with the application program to be executed. For example, by displaying the image in the enlarged display area 102 up to more detailed information than the image in the enlargement target frame 101, it is possible to display information hierarchically so that the user can easily understand. In addition, for example, by displaying an image in the enlarged display area 102 with an identifier included in the image within the enlargement target frame 101, selection information can be selected by a key operation or the like without a tap (pressing the display screen) operation. It becomes possible to do.

  Next, a specific example of the display screen 100 in the mobile phone terminal 1 will be described. In this specific example, the mobile phone terminal 1 connects to a server of a portal site via the Internet, displays the obtained one-page content on the display screen 100, and processes this display according to a user instruction. It is assumed that this is done.

  First, a specific example of the display screen 100 in the enlarged screen display control process and the enlarged screen movement control process will be described.

  In FIG. 10, for example, when a character or the like is small and difficult to see, the user touches the display screen 100 a with his / her finger 103 to enlarge a part of the content displayed on the display screen 100 a. Represents a state in which is pressed. At this time, if the enlarged display area 102a is in a “non-display” state, an enlarged screen display control process is performed, so that the enlargement target frame 101a and the enlarged display area 102a are displayed on the display screen 100a. Inside the enlarged display area 102a, the contents of the area surrounded by the enlargement target frame 101a are displayed in an enlarged state as in the display screen 100a of FIG.

  Here, the relative positional relationship between the enlargement target frame 101 and the enlarged display area 102 is determined according to constants (α, β) as shown in FIG. 9, for example (when the process of S36 in FIG. 3 is executed). ). Therefore, the enlargement target frame 101 and the enlargement display area 102 do not overlap each other, and the user can view the whole of both ranges simultaneously. Further, since the enlargement target frame 101 is displayed, the user can easily recognize which part on the display screen 100 is enlarged. Further, since the enlargement target frame 101 and the enlarged display area 102 are close to each other, the user can easily check both contents without moving the viewpoint greatly.

  When the user's finger 103 is moved (dragged) from the state of the display screen 100a in FIG. 10 to the state of the display screen 100b in order to change the portion to be enlarged, the enlarged screen movement control process described in FIG. 4 is executed. Is done.

  Accordingly, as the finger 103 moves, the display position of the enlargement target frame 101a and the display position of the enlargement display area 102a are automatically changed to the positions of the enlargement target frames 101b and 101c and the enlargement display areas 102b and 102c, for example. At this time, even if the enlargement target frame 101 is moved, it does not overlap with the enlarged display area 102. Further, for example, when it is expected that a part or the whole of the enlarged display area 102 protrudes from the display screen 100 at the movement destination, as shown in the display screen 100c of FIG. Is automatically positioned.

  Further, the following processing is performed based on the setting status of each parameter shown in FIG.

  When “enlarged screen concealment” of the parameter shown in FIG. 8A is turned on (yes), the display of the enlarged display area 102 is temporarily erased, and when the movement is completed, the enlarged display area 102 is displayed again. It is displayed on the display screen 100.

  When the “enlargement target frame reduction” parameter shown in FIG. 8A is turned on (yes), the size of the enlargement target frame 101 and the size of the enlarged display area 102 are temporarily set according to the moving speed. Reduced. For example, when the finger 103 is moved (dragged) from the state where the display screen 100a shown in FIG. 11 is displayed, the size of the enlargement target frame 101b is larger than that of the normal enlargement target frame 101a as in the display screen 100b. Get smaller. At the same time, the size of the enlarged display area 102b is also smaller than the size of the normal enlarged display area 102a. The enlargement ratio (R) in this case does not change during movement. When the movement is completed, as shown in the display screen 100d, the enlargement target frame 101d and the enlarged display area 102d are displayed in the same size as before the movement.

  When the “enlargement screen magnification reduction” parameter shown in FIG. 8A is turned on (yes), the enlargement magnification (R) and size (L, W) of the enlargement display area 102 correspond to the moving speed. Is temporarily reduced. For example, when the finger 103 is moved (dragged) from the state in which the display screen 100a shown in FIG. 11 is displayed, the enlargement magnification related to the enlarged display region 102c is smaller than usual (in this example, the same magnification is used). Therefore, the size is also smaller than usual (in this example, the same size as the enlargement target frame 101). In this case, the enlargement target area and the size of the enlargement target frame 101c surrounding the enlargement target area are the same as before the movement and do not change. When the movement is completed, as shown in the display screen 100d, the size and magnification of the enlarged display area 102d return to the original state.

  If the “dominant hand setting” parameter shown in FIG. 8A is turned on (yes), is the relative positional relationship between the enlargement target frame 101 to be displayed and the enlarged display area 102 “right-handed”? It changes automatically according to whether it is “left-handed”. The user can determine in advance the parameter indicating the “right-handed” or “left-handed” (the content of “handedness” shown in FIG. 8D). When “dominant hand setting” is on (yes), the parameters (X, Y) for determining the coordinates for displaying the enlarged display area 102 are different values depending on whether “right-handed” or “left-handed”. become.

  FIG. 12 shows a specific example of the positional relationship between the enlargement target frame 101 and the enlarged display area 102 on the display screen 100 when “left-handed” is selected. FIG. 13 shows a specific example of the positional relationship between the enlargement target frame 101 and the enlarged display area 102 on the display screen 100 when “right-handed” is selected. 12 and 13 are examples in which the enlargement target frame 101 is moved from the upper left to the center and lower right of the screen.

  In the case of “left-handed”, the position where the enlarged display area 102a is displayed is shifted to the lower right with respect to the enlargement target frame 101a as in the display screen 100a shown in FIG. Therefore, the entire enlarged display area 102 to be displayed is positioned so as not to be hidden by the finger 103 or the hand. When the position of the enlargement target frame 101a is moved to the position of the enlargement target frames 101b and 101c, the position of the enlargement display area 102a is moved to the position of the enlargement display areas 102b and 102c as in the display screens 100b and 100c of FIG. To do.

  In the case of “right-handed”, the display position of the enlarged display area 102a is shifted to the lower left with respect to the enlargement target frame 101a as in the display screen 100a shown in FIG. Therefore, the entire enlarged display area 102 to be displayed is positioned so as not to be hidden by the finger 103 or the hand. When the position of the enlargement target frame 101a is moved to the position of the enlargement target frames 101b and 101c, the position of the enlargement display area 102a is moved to the position of the enlargement display areas 102b and 102c as in the display screens 100b and 100c of FIG. To do.

  When “priority area designation” of the parameter shown in FIG. 8A is turned on (yes), the display position of the enlarged display area 102 is positioned at a high priority position on the display screen. In this case, the value of the parameter (X, Y) that determines the display position of the enlarged display area 102 includes the coordinates of the area with high priority in the screen area configuration of the parameter shown in FIG. Assigned.

  For example, in the display screen 100a shown in FIG. 14, it is assumed that one page of content to be displayed is composed of a plurality of independent frames F1, F2, and F3. In this example, since the range to be enlarged and the enlargement target frame 101a exist in the area of the frame F1, the area of the frame F2, which is a different area, and the area of the frame F3 in which advertisement information exists The position is preferentially determined so as to arrange the enlarged display area 102a. A higher priority can be assigned to an area where an advertisement exists. Differences in priority for each region, and the range and coordinates of each region can be assigned in the “screen area configuration” parameter shown in FIG. 8D. The coordinates for arranging the display area 102a are determined.

  In the display screen 100b shown in FIG. 14, it is assumed that the size of the enlarged display area 102b is expanded to a range corresponding to the entire width of the display screen 100b. In this case, the enlarged screen is displayed giving priority to the width of the area to be enlarged.

  In the example illustrated in FIG. 15, it is assumed that the content to be displayed is a map. As shown on the display screen 100a, the map includes a city area MA1 and a sea area MA2. In this case, the possibility that the display content of the sea area MA2 is necessary for the user is relatively small. Therefore, as shown in the display screen 100b, the enlarged display area 102b obtained by enlarging the visible information in the enlarged display frame 101 is preferentially arranged in the sea area MA2. In this case, by examining the difference in compression ratio for each area when compressing map data and the density distribution of information, for example, the sea area and the urban area can be automatically distinguished, so the result of the distinction is reflected. The priority information may be stored in the parameters shown in FIG. Therefore, the enlarged display area 102 can be preferentially positioned in an area such as the sea where the data compression rate is high or an information amount per unit area is small.

  Next, a specific example of the display screen 100 in the enlarged screen resizing control process will be described.

  As shown in FIG. 16, when the user presses the position inside the enlarged display area 102a displayed in the display screen 100a with the finger 103 and repeats the pressing operation without moving, a predetermined event is generated. be able to. For example, when link information is assigned to a character string or the like displayed at a corresponding position, an event of clicking the link can be generated. Note that the input position in the enlarged display area 102 can be associated with each coordinate of the enlargement target frame 101 by using the conversion result of the process of step S16 in FIG.

  When the user's finger 103 is moved (dragged) at a position inside the enlarged display area 102a displayed in the display screen 100a, the enlarged screen resize control process described with reference to FIG. 6 is performed. For example, as shown in the display screen 100a shown in FIG. 16, while the finger 103 presses the range of the enlarged display area 102a displayed on the display screen 100a, the position of the finger 103 is moved to the right side as shown in the display screen 100b. When moving (dragging) toward, the coordinates of the position pressed by the finger 103 approach the right side of the outline of the enlarged display area 102a. Then, when the distance between the coordinates of the finger 103 and the coordinates of the right side of the enlarged display area 102a is equal to or smaller than the enlargement threshold e, the right side of the enlarged display area 102b also changes in the position of the finger 103 as in the display screen 100b shown in FIG. Accordingly, the position of the left side of the enlarged display area 102b does not change, so the size of the enlarged display area 102b (in this case, corresponding to W in FIG. 9) is automatically enlarged. Further, as the size of the enlarged display area 102b is enlarged, the size of the enlargement target area and the size of the enlargement target frame 101b surrounding it are also enlarged, so that the enlarged display is performed as shown in the display screen 100b of FIG. More information is enlarged and displayed inside the area 102b. Instead of adjusting the size of the enlarged display area 102b, the position (display coordinates: X, Y) of the enlarged display area 102b may be adjusted.

  Next, a specific example of the display screen 100 in the application cooperation enlarged display control process will be described.

  For example, when displaying contents of a map or a train route map, a plurality of data with different scales are often prepared. As described above, when visible information such as an image included in the enlargement target frame 101 is enlarged as it is and displayed in the enlarged display area 102, a relatively large character or the like is displayed in the enlarged display area 102. Since it is displayed, it is useful for the user to read the contents of the enlargement target frame 101. In this case, the information amount itself of the visible information displayed in the enlarged display area 102 is the same as the inside of the enlargement target frame 101. Therefore, when displaying content in which a plurality of pieces of data having different scales are displayed, data having a different scale from the data displayed in the enlargement target frame 101 or the like is selected as data to be enlarged and displayed in the enlarged display area 102. Like that. Thereby, the amount of information that can be read by the user in the enlarged display area 102 can be increased. Such data with different scales may be acquired by, for example, the application unit 30 from a server via a website, or may be stored in advance in a storage unit (not shown) of the application unit 30.

  In the mobile phone device 1, when the “application cooperation expansion” parameter shown in FIG. 8A is turned on (yes), the application cooperation expansion display control process is performed. The contents are displayed in the enlarged display area 102. In the application cooperation enlarged display control process, the application cooperation unit 28 performs processing so as to cooperate with the operation of a specific application program that handles the display target content such as a map, and acquires data of contents having different scales. Is displayed in the enlarged display area 102 as enlarged information.

  For example, a train route map is displayed as content on the display screen 100 shown in FIG. 17, and a plurality of pieces of data with different scales are prepared in advance as data of this route map. As a result, the data displayed in the enlarged display area 102 of the display screen 100 shown in FIG. 17 can use data having a different scale from the route map displayed inside the enlargement target frame 101 or the like. .

  That is, in the enlargement target frame 101 of the display screen 100 shown in FIG. 17, for example, only “Shibuya” appears as a station due to the scale, but the inside of the enlargement display area 102 representing the contents of the same area Since there are three stations, “Shibuya”, “Ebisu”, and “Meguro”, the user confirms the contents in the enlarged display area 102, so that more information than inside the enlargement target frame 101 can be obtained. Can be obtained.

  For example, when visible information such as an image included in the enlargement target frame 101 is enlarged as it is and displayed in the enlarged display area 102, various candidate information that can be selected is included in the enlarged display area 102. Even if it is, the possibility that a part of the contents of each candidate information is missing and displayed is high. Can only be done by designation (pressing the touch panel etc.).

  For example, the display screen 100 shown in FIG. 18 displays the contents of a page of a certain portal site, which includes a large number of character strings including link information as selection candidate information. In addition, in the enlargement target frame 101 displayed in the display screen 100 of FIG. 18, information that can be five selection candidates “change job”, “part-time job”, “auction”, “communication”, and “bulletin board”. However, if the display content of the enlargement target frame 101 is enlarged as it is and displayed in the enlargement display area 102, a part of the character string of each selection candidate is missing and displayed. Reading a character string is not easy for the user.

  Therefore, when a predetermined operation mode is designated, for example, the contents of the enlargement target frame 101 are extracted for each selectable character string as shown in the enlarged display area 102 shown in FIG. In addition to shaping and arranging them, a number is assigned to each selection candidate, and each selection candidate is displayed in the enlarged display area 102 together with the number. By this processing, the user can read the entire five character strings of “change job”, “part-time job”, “auction”, “communication”, and “bulletin board” that can be selected.

  In addition, a number is assigned to each selection candidate, and not only detection of input coordinates by a user input operation but also input of a number by pressing an operation button to which a number or the like is assigned is accepted, and the corresponding number is assigned. It is also possible to select a selection candidate and generate a predetermined event. For example, as shown in FIG. 18, the contents of the enlarged display area 102 of the display screen 100 include “1. Job change”, “2. Part-time job”, “3. Auction”, “4. Communication”, “5. Bulletin board”. When the input unit 11 inputs, for example, when the user presses a button to which the number “3” is assigned in the state where the five selection candidates are displayed, “3. Auction” is selected among the selection candidates. It is possible to generate an event similar to the case where the link information assigned to this character string is clicked.

  According to such a mobile phone terminal 1, the operability of the user when a part of the display screen is enlarged and displayed can be greatly improved. About the function with which the mobile telephone terminal 1 is provided, it can also provide as a program which a computer can execute.

  It has been described that the area for performing enlarged display is the enlarged display area 102 and the area for performing enlarged display is the area within the enlargement target frame 101, and these areas are mainly rectangular. May have a shape other than a rectangle.

  The present invention relates to a display control device and an electronic device capable of improving operability related to a user's input operation and reading of display contents when the contents of a desired area on a display screen are enlarged and displayed in another place. Useful as equipment, programs, etc.
