  The source acquisition unit 10 is a part that acquires source information for displaying content. Specifically, the source acquisition unit 10 can acquire source information via a wired or wireless network (not shown). The source information is transmitted from, for example, a Web server (not shown) connected to the network. The source acquisition unit 10 can also acquire source information stored in advance in storage means (not shown) included in the information terminal 1. The source acquisition unit 10 sends the acquired source information to the selectable element detection unit 11.

  The selectable element detection unit 11 is a part that detects a selectable element that is an element that can be selected in the displayed content from the source information acquired by the source acquisition unit 10. Specifically, the selectable element detection unit 11 detects selectable elements by searching the source information, and acquires information such as the number of detected selectable elements and the display position of the selectable elements in the displayed content. To do. The selectable element detection unit 11 sends information about the selectable element detected and acquired from the source information to the screen size control unit 13.

  The user setting storage unit 12 is a part that stores a predetermined number related to display of selectable elements set by an input from the user. The user setting storage unit 12 stores the screen size control method in the screen size control unit 13. FIG. 3 is a diagram illustrating a configuration of the user setting storage unit 12 and an example of stored data. As illustrated in FIG. 3, the user setting storage unit 12 stores a display link number N as a predetermined number related to display of selectable elements and a screen size control method. The display link number N is the number of links displayed on the display unit 15 at a time under the control of the screen size control unit 13. The screen size control method defines how to set the content enlargement ratio when displaying the number of links according to the display link number N on the display unit 15. Details of the screen size control method will be described later. The data stored in the user setting storage unit 12 is set by the user via a predetermined input unit (not shown), for example. Thereby, the number of selectable elements displayed on the display unit 15 is maintained at a predetermined number desired by the user.

  The screen size control unit 13 is configured to display content on the display unit 15 such that a predetermined number of selectable elements set in advance among the selectable elements detected by the selectable element detection unit 11 are displayed. This is the part that determines the enlargement ratio. Specifically, the screen size control unit 13 reads the display link number N from the user setting storage unit 12, and displays the content represented by the source information so that selectable elements of the read link number N are displayed. The enlargement ratio for displaying on the unit 15 is determined.

Next, with reference to FIG. 4, a process for determining the enlargement ratio by the screen size control unit 13 will be described in detail. In the following description, links to other contents are used as examples of selectable elements. FIG. 4A shows the entire content represented by the source information. As shown in FIG. 4A, this content includes links L ₁ , L ₂ , and L ₃ . The screen size control unit 13 acquires the number N of display links and the screen size control method from the user setting storage unit 12. Here, it is assumed that the screen size control unit 13 has acquired “2” as the display link number N. Further, it is assumed that the screen size control unit 13 acquires “max” as the screen size control method.

  In this case, the screen size control unit 13 determines the maximum enlargement factor among the enlargement factors that can display the predetermined number of links on the display unit 15 as the enlargement factor when the content is displayed on the display unit 15. Specifically, for example, the screen size control unit 13 sequentially increases the enlargement ratio in a state where a predetermined reference point in the content is fixed at a predetermined reference position in the display unit 15, so that the entire two links are The enlargement ratio immediately before disappearing is determined as the enlargement ratio when the content is displayed on the display unit 15. The predetermined reference point in the content is set, for example, in the upper left corner of the content shown in FIG. 4A, and the predetermined reference position in the display unit 15 is set, for example, in the upper left of the area where the content can be displayed. However, both are not limited to the example of this embodiment. In addition, the screen size control unit 13 may adjust the enlargement ratio in a state where the center of gravity of the positions of the N links is fixed to the reference position in the center of the display unit 15, or a predetermined reference point in the content The predetermined reference position on the display unit 15 may be set automatically by the system, or may be set by user input.

FIG. 4B is a diagram illustrating an example of content displayed with the enlargement ratio determined in this way. As shown in FIG. 4B, the content is displayed at the maximum magnification among the magnifications that can display the _two links L ₁ and L ₂ . In other words, when the content is displayed with a larger enlargement ratio, at least a part of the links L ₁ and L ₂ is displayed. By determining the enlargement ratio in this way, the number of displayed links is maintained at a predetermined number set in advance, and the links are displayed larger on the display unit 15, so that the link selection operation is easier. It becomes.

  Further, when “min” is acquired as the screen size control method, the screen size control unit 13 can display (N + 1) links on the display unit 15 when N is a predetermined number related to link display. An enlargement ratio larger than the enlargement ratio is determined as an enlargement ratio when the content is displayed on the display unit 15. Further, the screen size control unit 13 sets the minimum enlargement ratio among the enlargement ratios larger than the enlargement ratio at which (N + 1) links can be displayed on the display unit 15 as the enlargement rate when the content is displayed on the display unit 15. It may be determined. Regarding the display of links, a state in which all links having a certain size are displayed can be defined as a state in which links are displayed. Further, a state where a part of the link is displayed may be defined as a state where the link is displayed.

  Specifically, for example, the screen size control unit 13 displays the content including (N + 1) links in a state where a predetermined reference point in the content is fixed at a predetermined reference position in the display unit 15. The enlargement rate when the content is displayed on the display unit 15 is the enlargement rate when the (N + 1) th link is excluded from the display area of the display unit 15 by sequentially increasing the enlargement rate from such an enlargement rate Determine as.

FIG. 4C is a diagram illustrating an example of content displayed with the magnification determined in this way when the display link number N is “2”. As shown in FIG. 4C, the content is displayed at an enlargement ratio that can display the _two links L ₁ and L ₂ , and the link L ₃ is displayed at an enlargement ratio that is not included in the display area. In other words, when the content is displayed with an even smaller enlargement ratio, three links L ₁ , L ₂ , and L _{3 that} are larger than 2 that is the predetermined number of display links are displayed. By determining the enlargement ratio in this way, the number of displayed links is surely maintained at a predetermined number set in advance, and the links are prevented from being excessively displayed on the display unit 15.

  Next, display control when a scroll operation for moving the display area in the content is performed on the information terminal 1 will be described. In the example illustrated in FIG. 5, the user setting storage unit 12 stores “2” as the display link number N, and stores “max” as the screen size control method.

FIG. 5A shows the entire content represented by the source information. As shown in FIG. 5A, this content includes links L _{1 to} L ₅ . First, for example, as shown in FIG. 5B, the screen size control unit 13 sets the upper left corner of the content as a predetermined reference point, and fixes this reference point to the upper left corner, which is a predetermined reference position on the display unit 15. In this state, the enlargement factor is sequentially increased, and the maximum enlargement factor among the enlargement factors that can be displayed by the _two links L ₁ and L ₂ is determined as the enlargement factor for displaying the content.

Subsequently, when scrolling is performed in which the display area of the content is moved downward, the screen size control unit 13 has a short distance from the reference position of the display unit 15 to the link position at the end of scrolling. Two links are extracted in order. And the screen size control part 13 determines the largest expansion rate among the expansion rates which can display two extracted links as an expansion rate for displaying a content. FIG. 5C is a diagram showing a display example of content at this time. As shown in FIG. 5 (c), content, links _L 3, _{L 4} of the links _L 1 ~L ₅ is at the maximum magnification of the possible magnification display.

Further, when scrolling is performed in which the display area in the content is moved downward, the screen size control unit 13 displays the link L ₄ among the links L _{1 to} L ₅ as shown in FIG. , L ₅ is the maximum magnification of the possible magnification display is determined as a magnification for displaying the content. The content shown in FIG. 5D is displayed with an enlargement rate smaller than the enlargement rate in the example of the content shown in FIG.

Note that if the magnification rate is changed each time scrolling is performed and content visibility is reduced, the initially set magnification rate may be maintained even if scrolling is repeatedly performed. Good. For example, when scrolling is performed from the state shown in FIG. 5B to the state shown in FIG. 5C, the enlargement ratio (FIG. 5B) set when the links L ₁ and L ₂ are displayed. )) May be used in the display of the links L ₃ and L ₄ (FIG. 5C) and the display of the links L ₄ and L ₅ (FIG. 5D).

  Again, a description will be given with reference to FIG. The display control unit 14 is a part that causes the display unit 15 to display content that has been enlarged with the enlargement rate determined by the screen size control unit 13. The display unit 15 is a part that displays content including a link under the control of the display control unit 14.

  First, the source acquisition unit 10 acquires source information for displaying content (S1). Subsequently, the screen size control unit 13 sets the initially set enlargement ratio as an enlargement ratio for displaying content. Then, the display control unit 14 displays the content represented by the source information using the enlargement ratio set by the screen size control unit 13 (S2). Note that the initial display of the content shown in step S2 may not be performed. That is, the process of step S3 may be performed following the process of step S1.

  In step S3, the selectable element detection unit 11 detects, from the source information acquired by the source acquisition unit 10, the links that are elements that can be selected and operated in the displayed content and the number of links included in the content (S3). . The selectable element detection unit 11 sends information related to the link detected and acquired from the source information to the screen size control unit 13.

  Subsequently, the screen size control unit 13 acquires the display link number N from the user setting storage unit 12 and determines whether or not the link number acquired from the selectable element detection unit 11 is equal to or less than the display link number N ( S4). If it is determined that the number of links is equal to or less than the number of displayed links N, the processing procedure proceeds to step S5. In step S5, the display control unit 14 displays the content represented by the source information on the display unit 15 without changing the enlargement ratio when displaying the content (S5).

  On the other hand, when it is not determined that the number of links is equal to or less than the display link number N, the processing procedure proceeds to step S6. In step S <b> 6, the screen size control unit 13 displays the content represented by the source information on the display unit 15 so that the links of the display link number N among the links detected by the selectable element detection unit 11 are displayed. An enlargement ratio for display is determined (S6). Then, the display control unit 14 causes the display unit 15 to display the content enlarged at the enlargement rate determined by the screen size control unit 13 (S7).

  In a state where the content is displayed on the display unit 15, the screen size control unit 13 determines whether or not a scroll operation for moving the display range in the content has been received (S8). When the scroll operation is accepted, the processing procedure returns to step S6, and the enlargement ratio determination process is performed again. On the other hand, when the scroll operation is not accepted, the processing procedure returns to step S7, and the display of the content is continued.

  Next, a display control program for causing a computer to function as the information terminal 1 of the present embodiment will be described. FIG. 7 is a diagram showing the configuration of the display control program 1m.

  The display control program 1m includes a main module 100m that centrally controls display control processing, a source acquisition module 10m, a selectable element detection module 11m, a user setting storage module 12m, a screen size control module 13m, a display control module 14m, and a display module.
