The first display 1207 corresponds to the first display unit 107. The second display 1208 corresponds to the second display unit 108.

  The display device 100 is realized by computer hardware and software executed by the CPU 1204. Generally, such software is stored and distributed in a recording medium such as a CD-ROM (Com-pact Disk Read Only Memory) 1210, read from the recording medium by the external storage unit 1202, and stored in the program memory 1205. Further, it is executed by the CPU 1204 described above. The computer hardware itself is general. Therefore, the most essential part of the present invention is software recorded on a recording medium such as a CD-ROM 1210.

  Referring to FIG. 3, the program executed on display device 100 has the following control structure for displaying a document.

  In step 401 (hereinafter step is abbreviated as S), the document data receiving unit 101 receives document data. The document data receiving unit 101 stores the received document data. When the document data is stored, the document data receiving unit 101 outputs the document data to the reduction unit 104. The reduction unit 104 creates image data that can display the entire document on the second display unit 108 based on the output document data. In the case of the present embodiment, the reduction unit 104 creates the image data so that a line is displayed instead of a character (as will be described later, a point may be displayed instead of a line. In the embodiment, a line is displayed instead of a character).

  In S <b> 402, the determination unit 103 specifies the first character displayed on the first display unit 107 in an enlarged manner. The character specified in this step is the first character of the document represented by the document data.

  In S403, the determination unit 103 calculates the number of characters in the character string that can be displayed on the first display unit 107. In addition, the determination unit 103 determines the character string to be displayed on the first display unit 107 according to the character specified by the user, the number of characters in the character string that can be displayed on the first display unit 107, and the character arrangement order in the document data. decide. However, when the operation input unit 102 receives data representing the display order, the determination unit 103 determines a character string to be displayed according to the data.

  In S <b> 404, the clarification unit 105 performs decoration processing on the portion of the image data created by the reduction unit 104 that corresponds to the character string that the determination unit 103 has determined to display on the first display unit 107. “Decoration processing” means that when the image data created by the reduction unit 104 is displayed on the second display unit 108, the form displayed on the first display unit 107 and the part not displayed on the first display unit 107 are different. In other words, it means changing the contents of the data created by the reduction unit 104. In the present embodiment, the clarification unit 105 performs a decoration process on the image data so that the portion displayed on the first display unit 107 is displayed with a thicker line than the other portion. When the decoration process is performed, the second display unit 108 displays the data.

  In S405, processing unit 106 creates character string data representing the character string determined by determination unit 103 among the document data. The first display unit 107 displays a character string based on the character string data created by the processing unit 106.

  In S406, operation input unit 102 accepts a user instruction. When the user instruction is accepted, the determination unit 103 determines whether or not the user instruction is an end instruction (an instruction to close the document or an instruction to end the document display program for realizing the display device 100). to decide. If it is determined that the instruction is to end (YES in S406), the process ends. If not (NO in S406), the process proceeds to S407.

  In step S407, the determination unit 103 determines whether the instruction is for changing the position where the user instruction is displayed. If it is determined that the instruction is to change the displayed position (YES in S407), the process proceeds to S408. If not (NO in S407), the process proceeds to S406.

  In step S <b> 408, the operation input unit 102 accepts designation of a position to be displayed on the first display unit 107 in the document data.

  With reference to FIG. 4 and FIG. 5, the operation of display device 100 based on the above-described structure and flowchart will be described.

  The document data receiving unit 101 receives document data. FIG. 4 shows a document accepted as document data at this time. When the document data is received, the reduction unit 104 creates image data so that the content of the document is displayed on the second display unit 108 (S401). When the image data is created, the determination unit 103 specifies the first character displayed on the first display unit 107 in an enlarged manner. The character designated in this step is the first character of the document shown in FIG. 4 (S402). When a character is designated, the determination unit 103 calculates the number of characters that can be displayed on the first display unit 107. When the number of characters is calculated, the determination unit 103 determines a character string to be displayed on the first display unit 107 (S403).

  When the character string is determined, the clarification unit 105 performs a decoration process on the portion of the image data created by the reduction unit 104 corresponding to the character string determined by the determination unit 103. When the decoration process is performed, the second display unit 108 displays the image subjected to the decoration process (S404). When the image is displayed on the second display unit, the processing unit 106 creates character string data representing the character string determined by the determination unit 103 in the document data. The first display unit 107 displays a character string based on the character string data created by the processing unit 106 (S405).

  When the character string is displayed on the first display unit 107, the operation input unit 102 receives a user instruction. The determination unit 103 determines whether the instruction received by the operation input unit 102 is an end instruction (S406). At this time, if an instruction to change the position to be displayed is input (NO in S406), determining unit 103 determines whether or not the instruction is to change the position at which the user instruction is displayed. (S407). At this time, since determination unit 103 determines that the instruction to change the position to be displayed is made (YES in S407), operation input unit 102 accepts designation of a position to be displayed on first display unit 107. (S408). When the designation of the position is accepted, an image and a character string are displayed on the second display unit 108 and the first display unit 107 through the processes of S403 to S405. The contents of the second display unit 108 and the first display unit 107 at this point will be described with reference to FIG. The second display unit 108 displays the document shown in FIG. 4 in a reduced size. Thereby, the layout of the document shown in FIG. 4 can be confirmed. Instead, it is difficult to display each character. Therefore, the second display unit 108 displays one line instead of displaying one line of characters (displays one point instead of displaying one character, or displays one rectangle. May be displayed). Of the lines displayed on the second display section 108, the contents on the first display section 107 ("There are airports where international flights take off and arrive. There are airports where international flights take off and arrive. Osaka and international The line of the part where the flight “departs / departs” is displayed is a thick line. The first display unit 107 displays the number of characters determined by the determination unit 103 among the documents shown in FIG. In the case of this embodiment, the user of the display device 100 can freely set the size of characters displayed on the first display unit 107, the number of characters displayed at a time, and the number of characters per line. In the case of FIG. 5, the number of characters displayed at one time is 48 characters, and the number of characters per line is 12 characters.

  As described above, the display device according to the present embodiment displays the document as an image on the second display unit. Since the document is displayed, the user can easily confirm the contents of the document. The number of scroll operations by the user can also be reduced. In addition, the first display unit clearly indicates a part of the document displayed on the first display unit by a displayable amount. As a result, it is possible to provide a display device that allows the user to easily grasp the contents while grasping the entire structure of the document data.

  In S408, the operation input unit 102 can accept designation of a position to be displayed on the first display unit 107 by various methods. In particular, the operation input unit 102 can accept the designation of one of the characters at a position that keeps a predetermined interval in the document as the designation of the first character of the portion displayed by the first display unit 107. it can. Examples of the predetermined interval include one character, one line (ie, an interval corresponding to one line in the first display unit 107), and one page (ie, once in the first display unit 107). For example). FIG. 6 is a diagram illustrating an example thereof. FIG. 6A shows a situation in which characters are displayed on the first display unit 107 in S405. When an instruction to scroll one character is received in S408, the contents of the second display unit 108 and the first display unit 107 after S405 are as shown in FIG. . While the display on the first display unit 107 in FIG. 6A starts from “international flights”, the display on the first display unit 107 in FIG. 6B starts from “international flights”. When an instruction to scroll one line is received in S408, the contents of the second display unit 108 and the first display unit 107 after S405 are as shown in FIG. . The display on the first display unit 107 in FIG. 6A starts from “international flights”, whereas the display on the first display unit 107 in FIG. 6C starts from “Yes”. When an instruction to scroll one page is received in S408, the contents of the second display unit 108 and the first display unit 107 after S405 are as shown in FIG. . While the display on the first display unit 107 in FIG. 6A starts from “international flights”, the display on the first display unit 107 in FIG. 6D starts from “has a port”. Further, the operation input unit 102 designates any one of the characters representing the end of the sentence (a punctuation mark in Japanese, a period or a question mark in English) in the document by the first display unit 107. It can be accepted as the designation of the part to be displayed. When the designation of the character representing the end of the sentence is accepted, the description on the first display unit 107 after S405 always starts from the character next to the designated character, that is, the beginning of the sentence. In the case of FIG. 6, when the display on the first display unit 107 in FIG. 6A starts from “international flights”, when the instruction to scroll one sentence is received, The display on the display unit 107 starts from “also in Chiba”. Further, when an instruction to scroll one sentence is received, the display on the first display unit 107 starts from “also in Osaka”.

  Further, the first display unit 107 may display a part of the document continuously (without line breaks) or by indicating the position of the line break. FIG. 7A shows the first display unit 107 and the second display unit 108 in the case where a part of a document is displayed by continuing lines. As shown in FIG. 7A, when the rows are continuously displayed, the first display portion 107 can display more information at a time. Since a lot of information is displayed at once, the first display unit 107 can display a part of the document efficiently. FIG. 7B shows the first display unit 107 and the second display unit 108 in the case where a part of a document is displayed by indicating the position of a line break. As shown in FIG. 7B, when the line break position is displayed and displayed, it is easy to grasp the contents of the document. Here, with reference to FIG. 7A and FIG. 7B, the meaning of “one line” described above, that is, the “interval corresponding to one line” in the first display unit 107 will be described. The “interval corresponding to one line” refers to an interval corresponding to the number of characters per line in the first display unit 107. From “Osaka” to “take off and landing” in FIG. 7A is the “interval corresponding to one line”. However, the character immediately before the line feed is regarded as a character at an interval corresponding to one line even before the position where the interval corresponding to the number of characters per line is taken. The “interval corresponding to one line” here is from “ru airport” to “yes” in FIG.

  Moreover, the method of displaying the part by which the content is displayed on the 1st display part 107 among the lines currently displayed on the 2nd display part 108 is not limited to a thick line. An underline may be provided instead of the thick line. Instead of a thick line, it may be displayed in reverse video. Instead of a thick line, a dotted line or a wavy line may be displayed. As long as color display is possible, different color lines may be displayed in the first display portion 107 where the content is displayed and where the content is not displayed. However, it is necessary to be able to distinguish between the part whose contents are displayed on the first display unit 107 and the part which is not.

  Further, the first display unit 107 and the second display unit 108 may be realized by a single display. In this case, after one screen is divided into at least two, a display corresponding to the first display unit 107 is displayed in one of the divisions, and the second display unit is displayed in any of the remaining divisions. A display corresponding to 108 is displayed.

<Second Embodiment>
Hereinafter, a second embodiment of the present invention will be described.

  Referring to FIG. 8, display device 120 according to the embodiment of the present invention has functions different from determination unit 103 according to the first embodiment, instead of determination unit 103 according to the first embodiment. A determination unit 113 for determining a portion to be displayed on the first display unit 107 is included (how will be described later). The determination unit 113 is also a circuit that determines the content of the decoration process added by the explicit unit 105 (the content of the decoration process may be determined by the explicit unit 105 itself. However, in the present embodiment, the determination unit 113 determines The contents are determined by the unit 113). Other hardware configurations are the same as those in the first embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 9, the program executed by display device 120 has the following control structure with respect to document display. In the flowchart shown in FIG. 9, the same step numbers are assigned to the processes shown in FIG. These processes are also the same (however, the same step number is assigned even when the determination unit 113 performs the same process instead of the determination unit 103). Therefore, detailed description thereof will not be repeated here.

  In step S <b> 601, the determination unit 113 determines the content of the decoration process added by the explicit unit 105. In the present embodiment, the contents of this decoration processing (that is, the form of the part corresponding to the part of the document determined to be displayed on the first display unit 107 by the determination unit 113) is an image (second display). In the row direction in the image displayed on the unit 108). The contents of the decoration process will be described with reference to FIG. In the case of the present embodiment, the determination unit 113 determines the content of the decoration process from the three types of candidates shown in FIG. The decoration process of the portion arranged in the first row in the second display unit 108 is “decoration process A”. This is a process in which double lines are displayed instead of characters. The decoration process of the portion arranged in the second row in the second display unit 108 is “decoration process B”. This is a process in which dotted lines are displayed instead of characters. The decoration process of the portion arranged in the third row in the second display unit 108 is “decoration process C”. This is a process in which a thick line is displayed instead of a character. Thereafter, the contents of the decoration process are determined in the same manner.

  In step S602, the clarification unit 105 performs decoration processing on the data created by the reduction unit 104 in accordance with the decoration processing determined by the determination unit 113. When the decoration process is performed, the second display unit 108 displays the document data subjected to the decoration process.

  In step S <b> 603, the processing unit 106 creates data to be displayed on the first display unit 107. When the data is created, the processing unit 106 performs a decoration process on the data according to the decoration process determined by the determination unit 113. At this time, the processing unit 106 performs a decoration process on the data so that the display form corresponds to the display form in the second display unit 108. When the decoration process is performed, the first display unit 107 displays the data subjected to the decoration process.

  An operation of display device 120 based on the structure and flowchart as described above will be described. Through the processes of S401 to S403, the determination unit 113 determines the content of the decoration process based on the display position on the first display unit 107 (S601).
