Description

  The present invention relates to a display control apparatus that controls display data including a plurality of types of information to be displayed on a display screen.

  The display devices of various electronic devices have a fixed resolution (vertical and horizontal dot numbers), and cannot display a document having a size exceeding the resolution when performing the same size display. For this reason, many electronic devices support a reduced display function, or have a basic function called “scroll”, which is a mechanism for moving and displaying a document with a size that protrudes from the display frame of the screen in any direction. Supported.

  The user event for invoking the scroll function is typically an operation event for a control called a scroll bar arranged at the right end or the lower end of the screen. By operating the scroll bar in the vertical direction on the right edge using a pointing device such as a mouse, the displayed document can be moved (scrolled) up or down on the screen, or the scroll bar in the horizontal direction on the bottom edge can be moved. By operating, the document being displayed can be moved (scrolled) to the left or right of the screen.

  However, in such an event, it is necessary to keep operating the pointing device during scrolling, and there is a drawback in that it cannot be neglected. Therefore, the following Patent Document 1 discloses a technique (hereinafter, referred to as “start” and “stop” of scrolling in response to a user operation, while automatically performing a scroll operation between them without relying on the user operation (hereinafter referred to as “the following”) , Referred to as prior art).

  According to this, since the user only needs to perform a required operation (such as a mouse operation) at two points of “start” and “stop” of scrolling, the above-described drawbacks can be solved.

JP 2009-104649 A

  As described above, in the conventional technique, there is no need to constantly operate the pointing device during scrolling, and there is an advantage that the trouble can be reduced. However, there are two effects of “start” and “stop” of the scroll. It is necessary to perform a required operation (mouse operation or the like) at the time, and in particular, the operation at the time of stopping is indispensable.

An object of the present invention is to enable easy display of information of a desired information type included in any position in display data.

The invention according to claim 1 is a display control device that controls to display display data including a plurality of types of information of different information types on a display screen, and includes a touch operation on the display screen and an operation content thereof. The detecting means for detecting and the operation content of the touch operation detected by the detecting means correspond to any one of the plurality of touch operation types associated with each of the plurality of types of information. and discriminating means for discriminating whether the to, wherein when it is determined to correspond to one of the touch operation type by discriminating means identifies the information type that is correlated to the touch operation type, displayed on the display screen the display position of the display data, display control for controlling to move displays the display position of the display data so that the display position containing information of the identified information type to be Characterized by comprising a stage, a.

According to the present invention, it is possible to easily display information of a desired information type included in any position in display data.

It is a principal part block diagram of the electronic device to which embodiment is applied. It is a figure which shows the control function of the control part 5 typically. It is a conceptual diagram of the scroll operation | movement of embodiment. It is a control flow figure of scroll operation of an embodiment. It is an improvement control flow figure of scroll operation of an embodiment.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a main part configuration diagram of an electronic apparatus to which the embodiment is applied. In this figure, an electronic device 1 visualizes an input unit 3 for capturing an arbitrary document 2, an operation unit 4 operated by a user, a control unit 5 for overall control of the entire operation of the electronic device 1, and a document 2. And a display unit 6 that can be displayed. Incidentally, the use of the electronic device 1 is not particularly limited. What is necessary is just to include each part (input part 3, operation part 4, control part 5, and display part 6) at least in the drawing.

  The document 2 is a file of a predetermined format that is appropriately produced for the purpose of visual display, and this file includes information such as characters, figures, photographs, and paintings alone or in combination. There are various file formats, but they can be roughly divided into text files and binary files. A text file is the simplest file format consisting of character information and control information. This text file is supported by most electronic devices equipped with a display device. HTML (HyperText Markup Language) is a format developed from text files. HTML includes control information that specifies the logical structure and appearance of a document in addition to document information, and can also embed image, audio, video, and link information (hyperlink) to other documents in the document. . HTML is also called a Web document, and can be reproduced and displayed on an electronic device equipped with a dedicated tool (Web browser). On the other hand, a binary-format document is a file created by a sentence creation software such as a word processor, and has a sentence structure that is more sophisticated than a text file or HTML, and can produce a more attractive sentence. Since each software is different, it can be reproduced and displayed only on an electronic device equipped with the corresponding software.

  As described above, the format of the document 2 is various, and the display control method differs depending on the format. However, in order to simplify the description, the simplest text file will be described below as an example. .

  Now, the problem of the present embodiment relates to “a scroll control device, a scroll control method and a program applied to various electronic devices including a display device”. Provided is a scroll control device, a scroll control method, and a program that can eliminate the need for user operation ", and a scroll operation performed when a document 2 having a size exceeding the display size of the display unit 6 is displayed on the display unit 6 It is to improve the operability of the user by improving the above.

  In order to achieve this problem, first, the operation unit 4 has a mechanism capable of detecting a scroll start operation and a scroll direction performed by the user. The first method for realizing this mechanism is a combination of a pointing device such as a mouse and a scroll bar. As is well known, by operating the scroll bar with a pointing device, the document 2 being displayed on the display unit 6 can be moved (scrolled) up and down or left and right on the screen. This is because the start and the direction of scrolling can be detected.

  The second method is a combination of a touch panel disposed on the display unit 6 and various touch operations (touch operations such as a fingertip and a pen tip; hereinafter, represented by the fingertip) performed on the touch panel. Is. As the touch operation, for example, “touch”, “long touch”, “tap”, “double tap”, “drag”, “flick” and the like are known. Touch is an operation of touching the touch panel with a fingertip, and long touch is a long touch. A tap is a momentary touch operation, and corresponds to a mouse click operation. The double tap is an operation of repeating the tap twice, and corresponds to a mouse double click operation. Dragging is an operation of moving the fingertip in any direction while touching the touch panel, and flicking is an operation of performing a “finger” operation after dragging. There are other operations (pinch) to narrow or widen the distance between the two fingertips. In short, one of these various touch operations may be assigned to the “scroll start operation”. For example, when “flick” is assigned, it is possible to determine that it is an instruction to start scrolling when “finger” operation is performed after dragging on the touch panel, and the scroll direction can be detected from the “finger” direction. .

The control unit 5 includes, for example, a CPU (Central Processing Unit) 5a, a ROM (Read Only Member) 5b, and a RAM (Random
(Access Memory) 5c and a microcomputer composed of necessary peripheral circuits, the control program stored in the ROM 5b is expanded in the RAM 5c, and the control program is executed by the CPU 5a, whereby the entire electronic device 1 is realized. It performs overall control of operations (such as operations related to scroll processing). Here, the control unit 5 using a microcomputer, that is, software resources such as a control program and the hardware resources such as the CPU 5a, the ROM 5b, the RAM 5c, and necessary peripheral circuits are organically coupled to each other. The control unit 5 is a so-called program control type that performs overall control of the entire operation, but is not limited thereto. For example, a part or all of the control may be realized by hard logic.

  FIG. 2 is a diagram schematically showing the control function of the control unit 5, and the illustrated control function is obtained by extracting the functions related to the display control and scroll control of the document 2 from the control function of the control unit 5. It is. In this figure, the control unit 5 includes a document structure analysis unit 10, a scroll start operation detection unit 11, a scroll direction detection unit 12, a scroll stop position detection unit 13, a scroll operation control unit 14, a display position determination unit 15, and a display. A control unit 16 and the like are provided.

  The document structure analysis unit 10 analyzes the sentence structure of the document 2 captured by the input unit 3. Here, as described above, the illustrated document 2 is a text file having the simplest structure. The text file includes displayable text information (text characters) and some control information (control characters), all of which are represented by a predetermined character code (ASCII code). The ASCII code can express not only single-byte characters such as alphabets A to Z, numeric values 0 to 9 and various symbols, but also double-byte characters such as kanji, hiragana, and katakana (display and print). In addition, various control characters such as text start and end, tab, and line feed are also defined as non-display (non-print) characters. The document structure analysis unit 10 analyzes the contents of the document 2 and distinguishes between display characters and control characters. Here, the document 2 is a text file having a simple structure, but the present invention is not limited to this. It may be an HTML that is an extension of a text file, or may be a binary file created by various dedicated software. Since these HTML and binary files also contain control information corresponding to the control characters of the text file, the document structure analysis unit 10 has their control information (although more complicated than the control information of the text file). It is only necessary to have a mechanism that can analyze.

  The scroll start operation detecting unit 11 monitors a user operation performed on the operation unit 4 at all times or every very short time, and determines whether or not the operation is a predetermined operation instructing “start of scroll”. To detect. Although this predetermined operation is not particularly limited, for example, the first method or the second method described above may be employed. Hereinafter, for convenience of explanation, this predetermined operation (operation for instructing to start scrolling) is referred to as “flick” operation in the second method, and when this flick operation is performed, the user is instructed to start scrolling. It shall be detected.

  Similarly to the scroll start operation detection unit 11, the scroll direction detection unit 12 monitors user operations performed on the operation unit 4 at all times or every very short time, and when a predetermined operation is performed, the operation is performed. To detect the direction of scrolling. For the sake of convenience of explanation, this predetermined operation is also a “flick” operation, and the direction of scrolling is detected from the direction of this flick (the direction of “finger”).

  The scroll stop position detection unit 13 is for detecting the scroll stop position of the document 2 in the scroll state on the display unit 6, and the principle of detection of the scroll stop position is that the contents of the document 2 are scrolled. The “predetermined information” is searched retroactively in the direction, and when the predetermined information is found, the position of the predetermined information is set as the scroll stop position. There are various “predetermined information”. For example, it may be a specific character or character string of display characters of a text file. For example, if the practicality is ignored, a display character string such as “stop scrolling here” may be used as the predetermined information. In this case, when the scroll stop position detection unit 13 looks back at the content of the document 2 in the scroll direction and finds a display character string “stop scrolling here”, the scroll stop position detection unit 13 determines the position of the character string as the scroll stop position. And

  Of course, in such an example, an unnecessary character string (“stop scrolling here”) is displayed on the screen, which is difficult to see and is not practically preferable. In practice, it is desirable to use a control character or control character string that is a non-display character as the “predetermined information”. For example, since the horizontal tag code is a non-display control character that designates character reduction in the horizontal direction, a combination of this tag code and a line feed code may be used as “predetermined information”. That is, a combination of a horizontal tag code and a line feed code may be embedded at an arbitrary position in the document 2. In this case, when the scroll stop position detection unit 13 searches the contents of the document 2 in the scroll direction and finds a combination of the horizontal tag code and the line feed code, the scroll stop position detection unit 13 scrolls the position of the combination of the horizontal tag code and the line feed code. The stop position.

  The “predetermined information” may be other than this. For example, in an HTML file, which is an advanced version of a text file, the format of a character string (font size, font color, bold font, underline, etc.) can be specified as appropriate, so these formats are specified as “predetermined information”. May be. For example, if a character string having a certain font size is designated as “predetermined information”, the scroll stop position detecting unit 13 retroactively reads the contents of the document 2 in the scroll direction, When the “character string” is found, the position of the “character string of a certain font size” is set as the scroll stop position. Alternatively, if a character string of a certain color is designated as “predetermined information”, the scroll stop position detection unit 13 goes back in the scroll direction to find the “character string of a certain color”. The position of the “character string of a certain color” is set as the scroll stop position. Alternatively, the “predetermined information” may be link information to a photo or image embedded in an HTML file or another document. When the scroll stop position detection unit 13 retroactively searches the content of the document 2 in the scroll direction and finds “link information to a photo, image, or other document”, the scroll stop position detection unit 13 The position of “link information” is set as the scroll stop position.

  Further, in the case of a binary file created by dedicated software such as a word processor, more special information can be used as “predetermined information”. For example, page break information, header / footer information of each page, layer information, and the like can be used as “predetermined information”.

  In any case, the scroll stop position detection unit 13 only needs to have a function of detecting the scroll stop position of the document 2 in the scroll state on the display unit 6, and the specific mode is exclusively the type of the document 2. In other words, it depends on whether it is a text file with a simple structure, an evolved HTML, or a binary file with a more complicated structure. What is necessary is just to use appropriate information according to the type of the document 2 actually used as the “predetermined information”, and the specific mode is merely a matter of design choice.

  The scroll operation control unit 14 controls control values (scroll speed, scroll direction, scroll, etc.) related to the scroll operation of the document 2 based on the detection results of the scroll start operation detection unit 11, the scroll direction detection unit 12, and the scroll stop position detection unit 13. Control value such as stop position) is calculated and output. Of these control values, the scroll speed may be a constant value, but may have a deceleration characteristic as in the prior art (Patent Document 1) described at the beginning. That is, the scroll speed may be linearly decreased from the start to the stop of the scroll. Or it is good also as an adaptive scroll speed according to the speed of the scroll start operation (here flick) detected by the scroll start operation detection part 11. FIG. That is, early scrolling may be used for an early flick, and late scrolling may be used for a slow flick. Furthermore, the scroll speed corresponding to the flick speed may be combined with the deceleration characteristic.

  The display position determination unit 15 determines the display position of the document 2 on the display unit 6. The reference of the display position is not particularly limited, but may be the origin coordinate position (upper left corner) on the screen of the display unit 6, for example. The display position determination unit 15 sequentially performs the display position determination operation at several points in time. The first time point is when the document 2 is initially displayed, and the initial display position of the document 2 is the head (start of sentence) of the document 2 or the latest final display position. The second time point is when a display position update other than scrolling is performed. For example, when an operation such as page up or page down is performed, the display position in this case is a position shifted by a certain number of lines or a page break code position. The third time point is when the scroll operation is being performed. In this case, the display position is updated smoothly with a constant speed or deceleration from the start to the stop of the scroll.

  The display control unit 16 outputs the display content of the document 2 captured by the input unit 3 to the display unit 6 and determines the display position of the document 2 on the display unit 6 according to the display position output from the display position determination unit 15. Update control.

  FIG. 3 is a conceptual diagram of the scroll operation of the embodiment. In this figure, the document 2 is larger than the display size of the display unit 6, for example, is vertically long. Here, for simplification of description, the display control of the document 2 on the display unit 6 is made at the same magnification, that is, the resolution of the display unit 6 (number of dots; for example, horizontal X dots × vertical Y dots) and 1 It shall be done in one-on-one. Since the display unit 6 cannot display such a document 2 on the display unit 6 at a time, a scroll operation is indispensable. Assume that a predetermined scroll start operation (flick) is performed on the touch panel of the display unit 6. A white arrow 17 indicates the flick operation, and the direction of the arrow 17 is a designated direction for scrolling. In this case, the document 2 scrolls from the bottom to the top of the drawing.

  Here, the hatched horizontal figure 18 drawn at an arbitrary position of the document 2 indicates “predetermined information” indicating a scroll stop position.

  In the present embodiment, the contents of the document 2 are retroactively searched in the scroll direction to find “predetermined information”. When the predetermined information is found, the position of the predetermined information is set as the scroll stop position, and the origin position of the screen is set. At the same time, scrolling automatically stops. For example, in the example of FIG. 3, when the “predetermined information” (the hatched horizontal figure 18) of the document 2 being scrolled is positioned at the origin coordinates (upper left corner of the screen) of the display unit 6, the scrolling automatically stops. .

  Therefore, according to the present embodiment, the “stop” of the scroll can be automatically performed without any user operation. Therefore, the user only has to specify the start and direction of the scroll, as described at the beginning. As compared with the prior art, it is possible to obtain a unique effect that operability can be improved.

  FIG. 4 is a control flow diagram of the scroll operation according to the embodiment. This control flow shows a simplified portion of a control program (stored in advance in the ROM 5b) executed by the CPU 5a of the control unit 5. In this control flow, first, the document 2 is read (step S1), and its contents are analyzed (step S2). Next, the display position of the document 2 is determined (step S3), the document 2 is displayed on the display unit 6, and it is determined whether or not a user operation related to display position update other than scrolling such as page up / down has been performed. If the operation is performed, the display position is determined again (step S3). If the operation is not performed, the scroll start operation detection unit 11 detects the scroll start operation. It is determined whether or not (step S5).

  If no scroll start operation is detected in step S5, the process returns to the display position update determination process (step S4). If a scroll start operation is detected, the scroll direction detection is performed next. The detection result (scroll direction) of the unit 12 is fetched (step S6), and scrolling is executed in the scroll direction (step S7).

  Next, while continuing scrolling, the contents of the document 2 are retroactively searched in the scroll direction to find “predetermined information” (step S8). If the predetermined information is not found, the document 2 being scrolled is at the end (end of the sentence). Whether or not it has been reached is determined (step S9). If the end of the sentence is not reached, scrolling is continued. If the end of the sentence is reached, scrolling is stopped (step S10) and the control flow is terminated. Also, when “predetermined information” is found, the position of the “predetermined information” is set to the origin coordinate of the display unit 6, and the scrolling is immediately stopped (step S10), and the control flow is ended.

  As described above, according to this control flow, when “predetermined information” is found in the document 2 being scrolled, the scrolling can be stopped immediately (step S10). There is no need to do this, and operability can be improved.

  In the above embodiment, the scroll stop condition is defined by one piece of information (predetermined information), but the present invention is not limited to this. You may improve so that several information can be used selectively.

  This is because the operation unit 4 of the embodiment can identify and detect various user operations. Specifically, the operation on the vertical and horizontal scroll bars as shown in the first method, or “touch”, “long touch”, and “tap” as shown in the second method. This is because operations such as “double tap”, “drag”, “flick” can be detected individually, and by assigning different information (predetermined information) for each of these operations, a plurality of information can be selectively selected. This is because it can be used.

  In the first method and the second method, the former uses a pointing device such as a mouse, while the latter uses a touch panel, and both use different user interfaces. Of course, it is also possible to operate the scroll bar with the touch panel, but this is an operation for a specific control (here, the scroll bar), while the second such as “touch” or “tap”. This method is different in that it is a free touch panel operation without fixing the object. Therefore, the aspect which enables selectively using several information using a 2nd method is demonstrated here. However, this description is merely an example, and there is no intention to positively exclude the first method. That is, if necessary, the first method and the second method may be used in combination.

  FIG. 5 is an improved control flowchart of the scroll operation according to the embodiment. This control flow is an improvement of part of the control flow of FIG. 4. Specifically, a new step S11 is inserted between step S5 and step S6 of the control flow of FIG. Step S12 is inserted between Step S8 and Step S8, and Step S8 of the control flow of FIG. 4 is replaced with Step S13.

  Here, the new step S11 is to store the type of the scroll start operation, and the type of the scroll start operation is “touch”, “long touch”, “tap” in the second method, “Double tap”, “drag”, “flick”, etc. Any of these operations can be distinguished and detected by the scroll start operation detector 11. In a new step S11, information indicating the type such as “touch”, “long touch”, “tap”, “double tap”, “drag”, “flick” detected by the scroll start operation detection unit 11 is stored in the RAM 5c. Memorize temporarily.

  Next, a new step S12 is to read the type of the scroll start operation, and the reading destination is a temporary storage area of the RAM 5c. That is, in this new step S12, the information indicating the type such as “touch”, “long touch”, “tap”, “double tap”, “drag”, “flick”, etc., temporarily stored in the previous step S11 is stored in the RAM 5c. Read from the temporary storage area.

  Next, in step S13 replaced with step S8, it is determined whether or not “predetermined information” corresponding to the type has been detected. The type is information indicating the type such as “touch”, “long touch”, “tap”, “double tap”, “drag”, “flick”, etc., which is primarily stored in the previous step S11. The “predetermined information” corresponding to the type is different information (predetermined information) assigned to each type.

An example of “predetermined information” corresponding to the type is as follows.
(1) “Touch” → predetermined information A
(2) “Long touch” → predetermined information B
(3) “Tap” → predetermined information C
(4) “Double tap” → predetermined information D
(5) “Drag” → predetermined information E
(6) “Flick” → predetermined information F

  Here, the predetermined information A to F means appropriate information according to the format of the document 2. For example, any display character (or display character string) or non-display character (or non-display character string) of a text file, HTML or binary file, or character string format (font size of HTML or binary file) Or link color of HTML, page break information of a binary file, header / footer information of each page, layer information, or the like.

  Thus, in the illustrated improved control flow, if the type of the scroll start operation is “touch”, the scroll can be stopped at the position of “predetermined information A” in the document 2, and the type of the scroll start operation is “long touch”. Then, scrolling can be stopped at the position of “predetermined information B” in the document 2. Further, if the type of the scroll start operation is “tap”, the scroll can be stopped at the position of “predetermined information C” of the document 2, and if the type of the scroll start operation is “double tap”, the “predetermined” of the document 2 Scrolling can be stopped at the position of information D ″. If the type of the scroll start operation is “drag”, the scroll can be stopped at the position of “predetermined information E” of the document 2, and if the type of the scroll start operation is “flick”, the “predetermined information” of the document 2 can be stopped. Scrolling can be stopped at the position F ″.

  Therefore, according to the illustrated improved control flow, the scroll can be stopped at various positions according to the type of the scroll start operation, so that a single “predetermined information” is detected as in the above embodiment. As compared with the case where the scrolling is stopped, it is possible to obtain a unique effect that the versatility is improved and the scrolling operation can be performed more easily.

  It should be noted that the examples of the predetermined information A to F are not limited to the above examples, and other arbitrary information may be specified. Such information can often be found from the layout of document 2. This is because the layout is generally made in order according to the production intention (editing policy) of the document 2. In particular, in the case of the document 2 having a high content and volume, the text content is structured so that it can be easily read ( This is because it is divided into appropriate paragraphs. This is because the reader only needs to read each structural unit, and the scrolling may be performed for each structural unit of the document 2 (that is, one piece of information). In general, such “one piece of information” is often clearly specified, so such explicit information (although it cannot be generally stated) is specified and specified. The information A to F may be appropriately specified.

  Further, in order to correctly perform scrolling completed for each structural unit of the document 2 (that is, one piece of information), it is necessary to definitely determine “one piece of information”. In general, a single piece of information such as a paragraph is clearly indicated by a conspicuous character or symbol, but the conspicuous character or symbol does not necessarily clearly indicate “a single piece of information”. For example, it may be just an editorial design. In such a case, with the simple mechanism of stopping scrolling when any “specific information” is detected as in the above embodiment, there is a possibility that “one piece of information” may be erroneously determined, There is a risk of stopping scrolling to a position where it does not exist.

  In order to cope with this, it is preferable to make a comprehensive determination on a plurality of pieces of information that may be used as the explicit information of “one piece of information”. For example, a paragraph is a typical example of “one piece of information”, but the item name of this paragraph is a large font, and a conspicuous font such as bold Gothic is used, and a conspicuous color is specified. Often. Therefore, when these conditions, that is, “large font”, “conspicuous font”, and “conspicuous color” are satisfied, it is determined that “one set of information” and the scrolling is stopped. Good. In this way, the inconvenience of stopping scrolling at an incorrect position can be avoided.

  Further, this idea may be developed as follows. That is, appropriate weighting is applied to each of a plurality of pieces of information that may be used as explicit information of “a group of one information”, and the weight values of the detected information are summed, and the total value is a predetermined threshold value. It may be determined that the information is “one piece of information”. The weight value may be set according to the possibility of being used as the explicit information of “one piece of information”. For example, in the case of a font type, since the “large font” is more likely to be used as explicit information for “one piece of information” than the “small font”, the latter weight value is more than the former weight value. Should be increased. Or, in the case of font colors, the brighter and brighter colors are more likely to be used as explicit information for “one piece of information” than the darker colors. Just increase the value. In this way, it is possible to accurately determine “one piece of information”, and it is possible to more reliably avoid the stop of scrolling to an incorrect position.
