The scroll control means controls the scroll amount according to the display size of characters contained in the content displayed on the display means.

Description

  The present invention relates to characters and images of e-mails, website contents, e-books, etc., and portable terminals such as mobile phones and PDAs (Personal Digital Assistants) and portable personal computers (hereinafter collectively referred to as “portable terminals”). The present invention relates to a scroll control device, a control method, and a control program that adjust the amount and speed of scrolling according to the size of displayed characters and images.

  In recent years, downsizing of computers has progressed, and computers with emphasis on portability have become widespread. A computer with emphasis on portability, that is, a portable terminal, has the same functions as a normal computer, but has features that are convenient to carry, such as reducing the size of the main unit and reducing the weight of the main unit. ing.

  Many of these mobile terminals connect to the Internet through a wireless line or public line, and acquire various contents (characters, images, etc.) from a web server connected to the Internet or directly from a storage medium. To do.

  By the way, portable terminals are required to be miniaturized because importance is attached to portability, and as a result, the display screen tends to be small. Therefore, the range of contents that can be displayed on the display screen is limited. For this reason, in many cases, the entire acquired content (characters, images, etc.) cannot be displayed on the display screen, and the display position on the screen is moved when the desired characters, images, etc. are to be displayed on the screen. It is necessary to move the screen (hereinafter referred to as scrolling) using the scroll function.

  Now, generally, the scroll amount in one scroll operation is constant. However, the display size of characters and the like displayed on the screen of the mobile terminal is not uniform and varies depending on the content expression method. For this reason, since the text on the scroll screen and the display of characters are likely to be overlooked, a technique for controlling the scroll amount and the scroll speed is disclosed. Japanese Patent Application Laid-Open No. 2004-228561 discloses a technique for determining scroll speed according to the total number of characters in a sentence and performing automatic scroll control. Japanese Patent Application Laid-Open No. 2004-228561 discloses a technique for automatically controlling scrolling by determining a scrolling speed or the like according to the number of dots used for displaying characters in a sentence.

JP 2003-108487 A JP 2008-129781 A

The scroll control technology described in the above-mentioned prior art documents allows the user to read the displayed content carefully by lowering the scroll speed as the number of characters displayed on the screen and the number of dots used for character display increase. Therefore, it is possible to satisfy the user's need to suppress oversight.
However, when the display size of the entire content to be displayed is large, the distance to be moved to the position (desired position) that the user wants to see is long, and the user wants to scroll to the desired position while reading diagonally. On the contrary, it may be annoying.

  By the way, for example, if the character size is small, the number of characters that can be displayed on one screen is large, so there is a low possibility of being missed (scrolling a character (row) to be read) with one scroll amount. On the other hand, if the character size is large, the number of characters that can be displayed on one screen is small, and there is a high possibility that the character will be missed with one scroll amount (a character (row) to be read is skipped). In order to suppress oversight, it is desirable to reduce the scroll amount when the character is large. At present, these problems cannot be solved by the above technique.

  Therefore, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide a mobile terminal capable of performing oblique reading while suppressing oversight in a scroll operation of the mobile terminal. Is to provide. That is, it is to provide a scroll control device, a control method, and a control program that can adjust the amount of scrolling executed according to the size of characters, images, etc. displayed on the screen.

  The scroll control device of the present invention is a scroll control device having display means for displaying content and scroll control means for performing scroll control of the content, and the scroll control means is included in the content displayed on the display means. The scroll amount is controlled according to the character display size.

  ADVANTAGE OF THE INVENTION According to this invention, in the scroll operation of a portable terminal, it becomes possible to read diagonally, suppressing overlooking. In other words, there is an effect that the amount of scrolling to be executed can be adjusted according to the size of characters and images displayed on the screen.

It is a block diagram of the scroll control apparatus which concerns on embodiment of this invention. FIG. 6 is a relationship diagram between a display size of characters and images according to an embodiment of the present invention and an adjusted scroll amount. It is a flowchart figure of the scroll control which concerns on embodiment of this invention.

  Next, the best mode for carrying out the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration diagram of a scroll control device according to an embodiment of the present invention. The scroll control device 100 includes a user interface unit (hereinafter abbreviated as UI unit) 101, an operation data receiving unit 102, an operation data analysis unit 103, a display unit 104, a screen generation unit 105, a screen content analysis unit 106, and scroll control. The unit 107 is configured.

  As a specific example, the UI unit 101 corresponds to a touch panel, a button, a mouse, and the like, and is a part to which a scroll operation by a user is input. Here, the scrolling operation is performed by a flicking operation on the touch panel, a mouse wheel operation of a mouse having a scroll operation wheel, or the like.

  The operation data receiving unit 102 digitizes the scroll operation input by the UI unit 101 and transmits it as operation data to the operation data analysis unit 103. As a specific example, in the UI unit 101, flicking or rotating the mouse wheel quantifies the amount of scroll operation that gives a scroll amount per unit time and transmits it. is there.

  The operation data analysis unit 103 analyzes operation data obtained by digitizing the scroll operation transmitted from the operation data receiving unit 102. Specifically, it is analyzed whether the scroll operation is more or less per time unit. For example, in the input of a scroll operation, if there are many scroll operations per time unit (that is, quickly flicking or quickly rotating the mouse wheel, etc.), the scroll amount is large or the scroll speed is fast. become. In addition, if the scroll operation is small per time unit (that is, performing a slow flick operation or slowly rotating the mouse wheel, etc.), the scroll amount is small or the scroll speed is slow. These analysis results are transmitted to the scroll control unit 107 as operation analysis data.

  The display unit 104 is a part on a mobile terminal where content composed of characters, images, and the like is displayed. The screen generation unit 105 generates image data of content composed of characters, images, and the like displayed on the display unit 104. The image data generated by the screen generation unit 105 is in a state in which content composed of characters, images, and the like is expanded on a virtual screen (a screen having an infinite size). However, since an actual screen (display unit 104) on which content is displayed has a finite size, not all image data is displayed. When only a part of the image data, that is, a part of the characters or images constituting the content is displayed on the actual screen (display unit 104), the remaining part is displayed by a scroll operation input to the UI unit 101. The image data is moved and displayed.

  The display content analysis unit 106 acquires size data such as characters and images that are constituent elements of the content image data from the screen generation unit 105 that generates the image data of the content displayed on the display unit 104, and Perform an analysis. Specifically, the display unit 104 detects whether a character, an image, or the like that is a component of the displayed content is large or small.

  More specifically, as a detection method in the case of a character size, in the case of a WEB browser, the character size information of HTML, the current state of enlargement / reduction of the browser, and the size of the displayed screen (display unit 104) are compared. Thus, the character size displayed on the display unit 104 is calculated. Further, in the case of a book viewer, the character size information of an arbitrary book format and the current state of enlargement / reduction of the viewer and the size of the displayed screen (display unit 104) are displayed on the display unit 104. Calculate the character size. Further, in the case of a picture in which characters are written, it is compared with the size of the screen (display unit 104) displayed by a character recognition function such as OCR technology or from the current state of enlargement / reduction of the picture viewer. The character size displayed on the display unit 104 is calculated.

  As a specific example, when all of the characters (strings) that are constituent elements of content cannot be displayed on the display unit 104, the size of the content displayed on the display unit 104 is assumed to be large, and the characters (strings) that are constituent elements of the content Is displayed on the display unit 104, the size of the content displayed on the display unit 104 is small. Note that the number of characters (columns) that are actually targeted can be set as appropriate depending on the size of the display unit 104. The detected character size is transmitted to the scroll control unit 107 as display analysis data.

  The scroll control unit 107 adjusts the scroll amount to be executed according to the size of characters and images displayed on the display unit 104. Specifically, when a certain scroll amount is input in the UI unit 101, if the characters and images displayed on the display unit 104 are large, the scroll amount to be executed is adjusted to be small and displayed. When the character or image displayed on the unit 104 is small, the scroll amount to be executed is adjusted to increase. Furthermore, if the UI unit 101 has a large amount of scroll input and the characters and images displayed on the display unit 104 are large, the scroll amount to be executed is adjusted to be smaller, and conversely When the input scroll amount is small and the characters and images displayed on the display unit 104 are small, the scroll amount to be executed can be adjusted to be larger.

  FIG. 2 is a relationship diagram between the display size of characters and images and the adjusted scroll amount according to the embodiment of the present invention. It shows how the scroll amount to be executed is adjusted according to the size of characters and images displayed on the display unit 104. Here, a case is shown in which the size of displayed characters, images, and the like is divided into three stages, but actually, not only three stages but also multiple stages can be adjusted.

  Here, the relationship between the size of characters and images and the adjusted scroll amount will be described in detail. As described above, when the displayed character or image is large, the scroll amount to be executed is adjusted to be small even if the input scroll amount is large. On the other hand, when the input scroll amount is small, or when the input scroll amount is medium or small, the scroll amount to be executed is adjusted to be equal to the input amount. However, there may be an adjustment that further reduces the amount of scrolling performed in accordance with the size of the displayed character or image. In addition, when the displayed characters, images, and the like are small, the reverse is true, and the description is omitted.

  In addition, about the size of a character, an image, etc., that is, if it says in FIG. 2, based on the display analysis data of the display content analysis part 106 about large, medium, and small, according to the user's visual recognition standard on the screen of a portable terminal, It can be modified as appropriate. The same applies to the adjustment of the scroll amount and speed to be executed.

FIG. 3 is a flowchart of scroll control in the embodiment of the present invention. The scroll control of the scroll control device 100 will be described in detail using this flowchart.
Note that this flowchart illustrates a case where the character size is large, medium, and small.

  First, in the UI unit 101, it is determined whether or not there is a scroll operation input from the user (step S110). If there is an input, the process proceeds to step S120, and if not, the process returns to step S110 again. Specific examples of the input operation include the above-described flick operation on the touch panel and the mouse wheel operation of the mouse equipped with the scroll operation wheel, as well as the case of using the automatic scroll function or the page up provided on the keyboard. / Page down key operation etc. As described above, regarding the input operation, there are various other operation methods, and any of them is included. In addition, it goes without saying that a portable terminal, a personal computer, and the like provided with such an input operation mechanism are included in the embodiment of the present invention.

  Next, in step S120, the character size displayed on the current display unit 104 is detected. The display content analysis unit 106 acquires character size data from the screen generation unit 105 that generates characters to be displayed on the display unit 104, and whether the displayed character is larger or smaller than the display unit 104. Is detected (step S120).

  And it is determined whether the character size displayed on the display part 104 is large (step S130). If larger, the process proceeds to step S140, and if not, the process proceeds to step S150.

  In step S140, the scroll control unit 107 adjusts the scroll amount according to the character size displayed on the display unit 104. Here, since the character size displayed on the display unit 104 is large, even if the input scroll amount is large, the scroll amount to be executed is reduced (step S140). Then, the process proceeds to step S180.

  In step S150, it is determined whether the character size displayed on the display unit 104 is small (step S150). If it is smaller, the process proceeds to step S160, and if not, the process proceeds to step S170.

  In step S <b> 160, the scroll control unit 107 adjusts the scroll amount according to the character size displayed on the display unit 104. Here, since the character size displayed on the display unit 104 is small, even if the input scroll amount is small, the scroll amount to be executed is increased (step S160). Then, the process proceeds to step S180.

  In step S170, the scroll control unit 107 adjusts the scroll amount according to the character size displayed on the display unit 104. Here, since the character size displayed on the display unit 104 is normal, the scroll amount to be executed is set to a medium level regardless of whether the input scroll amount is large or small (step S170). Then, the process proceeds to step S180.

  Finally, in step S180, the scroll amount set by the scroll control unit 107 is executed. When this scroll is executed, the process returns to step S110, and scroll control associated with a new scroll operation is executed.

  By using the present invention, it is possible to adjust the scroll amount and speed to be executed in accordance with the size of characters and images displayed on the screen of a mobile terminal or the like. Specifically, when the size of characters or images displayed on the screen of a mobile terminal or the like is large, the scroll amount on the screen to be executed is reduced with respect to the input scroll amount. Thereby, the visibility of characters and images on the screen can be improved.

  In this way, adjusting the scroll amount actually executed with respect to the input scroll amount is defined as adjusting the scroll sensitivity, so that characters, images, etc. displayed on the screen of the mobile terminal etc. If the size is large, adjustments have been made to reduce the scroll sensitivity. On the other hand, when the size of characters, images, etc. displayed on the screen of a portable terminal or the like is small, adjustment is performed to increase the scroll sensitivity.

  Although the embodiments have been described above, various modifications and changes can be made to these embodiments and specific examples without departing from the broad scope and scope of the present invention defined in the claims. Is possible.
