<Configuration of display control apparatus of the present invention>
FIG. 1 is a block diagram showing the configuration of an embodiment of the display control apparatus according to the present invention.
The display control device 1 shown in FIG. 1 mainly includes two display devices (a main display unit 20 and a sub display unit 21), an input device (an input unit 30) through which an instructor inputs a display instruction and the like, and a display instruction determination. Unit 40, display data generation unit 50, storage unit 70, and control unit 10 that controls the operation of each of these functional blocks.
Here, one display unit (main display unit 20) is mainly used by a presenter who makes a presentation, and the other display unit (sub display unit 21) is used in a scene such as a lecture or a briefing session by a presenter. It is assumed that the viewer who listens to the story of the presenter sees.

  The control unit 10 is mainly composed of a microcomputer including a CPU, ROM, RAM, I / O controller, timer, and the like. The CPU organically operates various hardware on the basis of a program stored in the ROM. Thus, the display control function of the present invention is realized.

The main display unit 20 is a part that displays display information viewed by the presenter. For example, an LCD, a CRT, a PDP, an organic EL display, or the like is used.
The display information displayed on the main display unit 20 is data generated by a main display data generation unit 51 described later and stored in the storage unit 70 as main display data 76.

  The sub display unit 21 is a part for displaying display information viewed by the viewer, and is arranged at a position different from the main display unit 20, and displays part or all of the display information displayed on the main display unit 20. As the sub display unit 21, an LCD, a PDP, an organic EL display, or the like can be used. Moreover, it is preferable to use a large-screen display as the sub display unit 21 in a case where explanations are given to many viewers. The sub display unit 21 is not limited to one, and may include two or more.

Further, when the presenter and the viewer receiving the explanation face each other on a one-to-one basis, the main and sub display portions are integrally formed, the main display portion 20 is disposed on the front surface, and the sub display portion 21 is disposed on the rear surface. You may use the arrange | positioned double-sided display apparatus.
In addition, an independent display device is used as the sub display unit 21, the display control device and the display device are connected via a network such as a LAN, and display information viewed by the viewer is displayed from the display control device to the display device (sub display). Display unit).
The sub display unit 21 displays the display content of the sub display data 77 generated by a sub display data generation unit 52 described later and stored in the storage unit 70.

The input unit 30 is a part where an instructor inputs display instructions and information such as characters, figures, symbols, and the like, and for example, a keyboard 31, a mouse 32, a touch panel 33, a touch pad, or the like is used.
Here, the display instruction means an input for designating a desired area and display mode (for example, display or non-display) of display information (content) displayed on the display screen of the main display unit 20.

When the display information is text data including a character string, the display instruction is input by an operation for designating a desired character string in the text data. For example, inputting with a finger or a pen so as to trace a desired designated character string in the display information displayed on the display screen of the main display unit 20 corresponds to a display instruction. The traced character string is display data belonging to the area designated by the display instruction.
The display mode mainly means display and non-display, and other than this, color designation, typeface designation, underline, strikethrough, blinking designation, enlargement / reduction designation, reverse display, and the like are also included.

The input display instruction is an instruction for designating whether display data belonging to the designated area is displayed on the sub-display unit 21 or not.
For example, as illustrated in FIG. 3A, it is assumed that the presenter traces a character string that is a desired designated area on the display screen of the main display unit 20 with a finger while the character string is displayed. At this time, after the display instruction is input, as shown in FIG. 3B, on the display screen of the main display unit 20, the character string specified by tracing is displayed in an underlined form.

When the display character string of the main display unit 20 is traced and a display instruction is input, the same display data as the display data belonging to the underlined designated area is shown in FIG. As shown in FIG.
On the other hand, as shown in FIG. 3B, when the underlined character string is displayed on the display screen of the main display unit 20, the underlined character string is traced with a finger. As shown in FIG. 4A, the display data belonging to the designated area is not displayed on the display screen of the sub display unit 21.

The display instruction determination unit 40 is a part that determines the content of the display instruction input by the input unit 30. Further, based on the determination result, display instruction information 75 is generated and stored in the storage unit 70. Specifically, the display data belonging to the specified area and the display mode specified by the display instruction are determined from the input display instruction.
The determination of the display instruction is performed based on the display control method information 74 stored in advance in the storage unit 70. Here, it is checked which of the display control method information 74 as shown in FIG.

For example, if the input display instruction is a trace of a designated character string in a desired area A in a normal display character string as shown in FIG. 3B, the display instruction is as shown in FIG. Since it matches the instruction content of the rule R1 of the display control method information 74 in (b), it is determined that a display instruction for displaying the display data (underlined character string) belonging to the area A is input as display control. .
When a display instruction for tracing a character string with a finger as shown in FIG. 3B is input, an area traced with a finger is displayed on the display screen of the sub display unit 21 as shown in FIG. The character string A is displayed.

The display data generation unit 50 is a part that generates display data to be displayed on the main display unit 20 and the sub display unit 21 of the display control device 1.
The display data generation unit 50 includes a main display data generation unit 51 and a sub display data generation unit 52.
The main display data generation unit 51 is a part that generates main display data 76 to be displayed on the main display unit 20 of the display control device 1.
The sub display data generation unit 52 is a part that generates sub display data 77 to be displayed on the sub display unit 21 of the display control device 1.

  The main display data 76 and the sub display data 77 extract information to be displayed from the display information (content) 73 stored in the storage unit 70 in advance, and correspond to the display instruction information 75 for the extracted display information. Display data generated by applying a predetermined change based on the display control method information 74 to be displayed.

For example, when a display instruction is input, the display instruction determining unit 40 determines that the sub display data generating unit 52 of the display data generating unit 50 includes display data belonging to the area specified by the display instruction among the sub display data. The sub display data is changed so as to be displayed on the sub display unit 21 of the display control device in the display mode.
Further, the display data belonging to the area specified by the input display instruction is displayed on the main display unit 20 of the display control device in a display mode that can be identified (for example, underlined display). Process the display data.
The display instruction determination unit 40 and the display data generation unit 50 are functional blocks that are executed by the control unit 10 mainly based on the control programs (71, 72) stored in the storage unit 70.

The storage unit 70 is a part for storing information and programs used in the display control device 1 of the present invention, and is a semiconductor storage element such as ROM, RAM, flash memory, a storage device such as HDD, SSD, and the like. A storage medium is used.
The storage unit 70 mainly stores a main control program 71, a sub control program 72, display information (content) 73, display control method information 74, display instruction information 75, main display data 76, and sub display data 77. In addition to this, information necessary for executing various functions of the display control device 1 is stored.

The main control program 71 mainly describes the procedure for determining the input display instruction and generating, storing, and displaying the display data (main display data 76) displayed on the main display unit 20 of the display control device 1. Program.
The sub-control program 72 is a program that mainly describes the procedures for generating, storing and displaying display data (sub-display data 77) displayed on the sub-display unit 21 of the display control device 1.

The display information 73 is information (contents) prepared in advance for display on the two display units (20, 21), and is, for example, information such as documents, drawings, and images used in the presentation.
The display information 73 itself is not data to be displayed but main display data 76 and sub display data 77 generated by using the display information 73 is data to be displayed on the display unit (20, 21).

FIG. 2A illustrates an example of display information (content) according to an embodiment.
FIG. 2A shows the character information related to “nuclear energy”, but the display information 73 is not limited to such character information, and may be a figure, an image, or the like.
When displaying the display information of FIG. 2A on the main display unit 20 as it is, for example, the display information is displayed as shown in FIG.

The display control method information 74 is information relating to display modes such as display and non-display of display data, and is information defining how the display data is displayed.
This information 74 is set in advance when the display control apparatus 1 is designed, but the user of the display control apparatus 1 may be able to change the setting independently.
FIG. 2B shows an explanatory diagram of one embodiment of the display control method information 74.
Here, two pieces of information (R1, R2) are shown, and for ease of explanation, each piece of information 74 includes instruction contents and display control. However, the actual storage content of the information 74 is stored in a format (numerical value or symbol) that can be used by the control program (71, 72).

The instruction content of the information 74 means a display instruction input by the user. The display instruction is input by an instructor who uses the display control device 1, and the instruction content is displayed on the main display unit 20.
The display control of the information 74 is not the display control for the main display data 76 displayed on the main display unit 20 of the display control device 1 but the display control for the sub display data 77 displayed on the sub display unit 21 of the display control device 1. Means.

  In the information R1 in FIG. 2B, the instruction content is “designate the area A of the display character string”, and the display control is “display the character string of the area A”. If the display instruction input by the input unit 30 is a trace of the desired area A with a finger or a pen in the display information displayed on the main display section 20, the information R1 is the traced area. It means that information (character string) belonging to A is displayed on the sub display unit 21.

Here, the information belonging to the region A is displayed on the main display unit 20 in a manner with an underline added, for example. As a result, the information belonging to the underlined region A is distinguished from other display information displayed on the display screen of the main display unit 20 and is information displayed on the sub display unit 21.
For example, in the display information shown in FIG. 3B, the underlined portion “Nuclear power station uses nuclear energy” is information (character string) belonging to region A. By looking, it can be easily confirmed that the character string in the area A is also visible to the viewer watching the sub display unit 21.

Further, as described above, the content of the display control of the information R 1 corresponds to the sub display data 77.
Therefore, when a display instruction corresponding to R1 is input, for example, display information (character string) belonging to the underlined area A as shown in FIG. 3B is displayed on the sub display unit 21. , As shown in FIG. 4B.

When displaying the display information belonging to the same area A on the main display unit 20 of the display control device 1, it is displayed with an underline. However, the display information is not limited to this, and the presenter identifies it with other character strings. Any display mode can be used.
For example, the display information (character string) belonging to the region A is displayed on the main display unit 20 so that the presenter can clearly understand that the display information belonging to the region A is also displayed on the sub display unit 21. May be displayed in a different color or different typeface from other information.

In addition, in the information R2 in FIG. 2B, the instruction content is “undesignate the display character string area A” and the display control is “non-display of the character string in area A”.
This information R2 is the part of the traced area A when the area A of the display information (character string) underlined by the display instruction input by the input unit 30 is traced with a finger or a pen. It is assumed that the information (character string) displayed in is not displayed (cancellation of designation) on the sub display unit 21.

  Here, when a display instruction corresponding to the instruction content of the information R2 is input, the display information (character string) of the area A that is displayed underlined in the main display unit 20 is deleted. Return to the display of text only. For example, the display state in FIG. 3B changes to the display state in FIG.

On the other hand, when a display instruction corresponding to the instruction content of the information R2 is input, the sub-display unit 21 viewed by the viewer changes from the display shown in FIG. 4B to the display shown in FIG. . That is, the character string belonging to the area A displayed on the sub display unit 21 as shown in FIG. 4B is not displayed.
The presenter who uses the display control apparatus 1 sees that the character string belonging to the area A is hidden by the viewer watching the sub display unit 21 by looking at the display screen of FIG. It can be easily confirmed.

As the display control method information 74, two specific examples (R1, R2) are shown in FIG. 4B, but the display control method information 74 is not limited to this.
In addition to this, for example, a display instruction such as underlining or painting with color C may be defined in advance.

In the storage unit 70 of FIG. 1, the display instruction information 75 temporarily stores the contents of the display instruction input by the user using the input unit 30.
The display instruction specifies display data belonging to a desired area of the display information displayed on the display unit 20 and a display mode. For example, as shown in FIG. The presenter who is the user specifies the desired area A by tracing the display screen with a finger or a pen. The display instruction information 75 is created and stored by analyzing the position of the display screen in the range traced with the finger or the like and the position of the information displayed on the display screen.

The display instruction information 75 is, for example, information as shown in FIGS. 2C, 2D, and 2E, and mainly includes information on a specified range and specified contents.
Here, the designated range means a desired area A designated by a display instruction, and indicates the position of information (character string) displayed on the display screen of the inputted area A.

When the information displayed on the main display unit 20 is character information as shown in FIG. 2A, the area A is designated by the number of rows and the number of columns. Specifically, from the position traced with the input finger and the positional relationship between the sentences displayed on the display screen, the number of lines and columns of the first (upper left) characters of the sentences belonging to the region A, and the last ( The number of lines and the number of columns in the lower right) are obtained and stored as ranges.
For example, in the case of FIG. 2D, the display instruction indicated by the area A is from the first row first column character of the sentence displayed on the main display unit 20 to the second row ninth column. Means the part up to

The designation content of the display instruction information 75 designates display or non-display on the sub display unit 21.
In the embodiment of the present invention, for example, when a display instruction in which an underlined character string portion is traced with a finger is input, this means that the character string portion is not displayed. That is, the underlined character string belonging to the region A traced with a finger means that it is not displayed when displayed on the sub display unit 21.
In addition, if a display instruction is input by tracing a character string part without an underline with a finger, it means that the character string part is displayed. In other words, an underlined character string belonging to the area A traced with a finger is displayed as an underlined character string when displayed on the sub display unit 21. Further, the main display unit 20 displays an underline added to the character string without the underline.

The display instruction information 75 is not limited to this, and a display mode may be designated. For example, you may designate the color type when displaying the character string which belongs to the area | region A traced with the finger | toe on a display part (20, 21). For example, the color type may be set in advance before the user inputs a display instruction.
If no color is specified, the characters may be displayed in the same color as characters outside the display instruction range, and may be displayed in a predetermined standard color (for example, black).
However, when a color different from the standard color is set, the text belonging to the area A is displayed on the display unit (20, 21) with the specified color, so that both the presenter and the viewer are displayed in the standard color. And the text in the region A can be easily distinguished.
Further, the presenter can easily confirm that the viewer is viewing the same sentence as the sentence by looking at the part of the sentence displayed in the designated color.

For example, the display instruction information 75 shown in FIG. 2D is information generated when the character string in the area A is traced as shown in FIG. 3B in the display state shown in FIG. is there. The display instruction information 75 shown in FIG. 2 (e) is information generated when the underlined character string is traced with a finger in the display state of FIG. 3 (b).
The display instruction information 75 is generated by the display instruction determination unit 40, and is used when the main display data generation unit 51 and the sub display data generation unit 52 generate the main display data 76 and the sub display data 77, respectively.

  The display instruction may be input using any one of the keyboard 31, the mouse 32, and the touch panel 33. However, as shown in FIG. 3B, the user inputs the display instruction with a finger on the display screen. In this case, the touch panel 33 is used.

The main display data 76 in the storage unit 70 is data generated by the main display data generation unit 51 and stores display data for actually displaying the display information 73 on the main display unit 20 of the display control device 1. It is.
The main display data 76 is data obtained by converting the display information 73 into data in a format that can be displayed on the display screen of the main display unit 20, and is stored as so-called bitmap data.
When the display instruction is input, the main display unit 20 displays the input display instruction information so as to overlap the range of the character string designated by the display instruction. Here, the input display instruction information means, for example, adding an underline to a character string in a range traced with a finger. In addition to the underline, the typeface or color may be changed, a strikethrough may be added, blinking may be specified, enlargement / reduction may be specified, and reverse display may be performed.
The sub display data 77 is data generated by the sub display data generation unit 52, stores display data for actually displaying the display information 73 on the sub display unit 21, and is bitmap data.

FIGS. 3A and 3B are explanatory diagrams of an embodiment of a display screen displayed on the main display unit 20 of the display control device 1.
FIG. 3A shows a display screen in which a part of the display information 73 stored in the storage unit 70 is displayed as usual.
FIG. 3B shows a display screen when the presenter inputs a display instruction in the display state of FIG. 3A, and an underline is added to the character string traced with the finger. The display state is shown.

When a display instruction as shown in FIG. 3B is input, display instruction information 75 shown in FIG. 2D is generated.
In addition, when a display instruction such as tracing the underlined character string with a finger is input after the display instruction as shown in FIG. 3B is input, the display instruction as shown in FIG. Information 75 is generated, and the display returns to the display as shown in FIG.
That is, when an input to cancel the input display instruction is made, display information is displayed on the main display unit 20 and the sub display unit 21 in the display mode before the display instruction is input. The display data generation unit changes the main display data and the sub display data.

FIGS. 4A and 4B are explanatory diagrams of an example of a display screen displayed on the sub display unit 21. FIG. Information displayed on the sub display unit 21 is displayed based on the sub display data 77. Here, the “nuclear energy” on the first line and the arrow on the second line are fixedly displayed portions.
FIG. 4B shows an example of a display screen displayed on the sub-display unit 21 when the presenter inputs a display instruction corresponding to R1 in FIG. It is a thing. When the display screen of FIG. 3B is displayed on the main display unit 20 of the display control device 1, the display screen of FIG. 4B is displayed on the sub display unit 21. That is, the same character string as the character string displayed on the main display unit 20 with an underline is displayed on the sub display unit 120.

FIG. 4A shows a display screen displayed on the sub display unit 21 when the display instruction input by the presenter is canceled (erased) as shown in FIG. An example is shown.
In other words, the display control device 1 shows a display screen displayed on the sub-display unit 21 when the presenter inputs a display instruction corresponding to R2 in FIG.
When the display instruction is canceled, a display screen as shown in FIG. 3A is displayed on the main display unit 20 of the display control apparatus 1. At that time, as shown in FIG. In the unit 21, the displayed character string is hidden in the display mode before the display instruction is input.

The sub display data 77 displayed on the sub display unit 21 is generated from the same display information 73 that generates the main display data 76, and is displayed on the sub display unit 21 separately from the display information 73. It is not necessary to create display information for the purpose.
That is, since it is not necessary to separately create display information to be displayed on the two display units (20, 21), the display information that is the basis of the main and sub display data can be easily created. In the control device 1, the sub-display data 77 intended by the presenter can be easily generated simply by the presenter inputting a display instruction as shown in FIG.
In addition, by changing the display instruction range to a part intended by the presenter, for example, the part displayed on the sub display unit 21 and the part not displayed can be easily changed only by changing the part traced with a finger. can do.

<Display control of main display data by main control program>
FIG. 5 shows a flowchart of an embodiment of display control processing of main display data in the display control device. This flowchart is executed by the main control program 71.
In FIG. 5, based on the display instruction input in the display control apparatus 1, the instruction character string is displayed on the main display unit 20 with or without an underline.

In step S1 of FIG. 5, the control unit 10 acquires display information (content) 73 to be displayed on the main display unit 20 from the storage unit 70, and causes the main display data generation unit 51 to generate main display data 76, Main display data 76 is displayed on the main display unit 20.
At this time, for example, the same display as in FIG.

In step S <b> 2, the control unit 10 checks whether there is an input meaning a display instruction by the input unit 30. For example, the touch panel 33 is used to check whether or not an input indicating a desired character string has been made by a finger.
The presenter views the display content of the display screen of the display unit 20 and inputs a display instruction by selectively tracing the character string portion desired to be displayed on the sub display unit 21.
If no display instruction is input, the process returns to step S1. Alternatively, step S2 is looped. If the display instruction is input as described above, the process proceeds to step S3.

In step S3, the display instruction determination unit 40 analyzes the input display instruction. Here, the input position coordinates specifying the position of the input display instruction are acquired.
In step S4, when the display content is a character string, the area A of the character string displayed at the input position coordinates is specified.
Further, with reference to the display control method information 74, it is determined to which information the input display instruction corresponds to the preset information 74.
When the display character string belonging to the area A is not underlined, it is determined that the “display control” of the input display instruction instructs to display the character string. That is, it is determined that the input display instruction corresponds to R1 of the information 74.

Further, in step S <b> 4, the display instruction determination unit 40 acquires an instruction character string from the analysis result, generates display instruction information 75 corresponding to the input display instruction, and stores the display instruction information 75 in the storage unit 70.
For example, as shown in FIG. 3B, when a display instruction that traces the character string portion of “Nuclear power station uses nuclear energy” is displayed, the display instruction information as shown in FIG. 75 is stored in the storage unit 70. Here, it is assumed that the first “original” is in the first row and the first column, and the last “to” is in the second row and the ninth column.

In step S5, the control unit 10 checks whether or not the input of the display instruction has been completed. Whether or not the input of the display instruction has been completed can be determined by, for example, releasing the mouse button that has been pressed.
When the input of the display instruction is completed, the process proceeds to step S6. Otherwise, the process returns to step S3.
In step S6, it is checked whether or not the display form before the input instruction character string is traced is an underlined display. If the instruction character string is displayed with an underline, the process proceeds to step S7. If the instruction character string is not displayed with an underline, the process proceeds to step S8.

In step S7, the instruction character string is changed to a display without an underline. That is, the input instruction character string is changed to display data without an underline and stored in the main display data 76 of the storage unit 70 and displayed on the main display unit 20.
At this time, for example, as shown in FIG. 3A, a character string without an underline is displayed. Thereafter, the process returns to step S2.

In step S8, the instruction character string is changed to an underlined display. That is, the input instruction character string is changed to underlined display data and stored in the main display data 76 of the storage unit 70 and displayed on the main display unit 20.
At this time, for example, as shown in FIG. 3B, an underlined character string is displayed. Thereafter, the process returns to step S2.

<Sub-display data display control by sub-control program>
FIG. 6 shows a flowchart of an embodiment of the display control process of the sub display data in the display control apparatus.
Here, the sub display data 77 is displayed on the sub display unit 21 of the display control device 1.
This flowchart is executed by the sub-control program 72.

In step S31, the control unit 10 checks whether or not a new display instruction has been input.
Here, the display instruction information 75 is not overwritten every time there is a display instruction, but a history is stored and the previous display instruction information 75 is also left.
Therefore, whether or not a new display instruction has been input may be checked by checking whether or not the previous display instruction information 75 is different from the display instruction information 75 for the display instruction input this time.
If there is an input for the first time, or if a display instruction different from the previous display instruction is input, the process proceeds to step S32.
Further, if there is no input, or if there is no change even if there is an input, the display instruction is the same as the previous time and there is no change, step S31 is looped.

In step S32, the sub display data generation unit 52 acquires the display information (content) 73 displayed on the main display unit 20 one character at a time from the top, and also acquires information (coordinate values) on the display position of the character. To do.
In step S33, it is checked whether or not the display method check in the following steps has been completed for all characters of the displayed display information.
If all the characters have been checked, the process proceeds to step S34, and if not, the process proceeds to step S35.

In step S35, it is checked whether or not the display position of the currently focused character belongs to the display instruction range indicated by the display instruction information 75 for the new display instruction.
If it is within the range of the display instruction, the process proceeds to step S36, and if not, the process proceeds to step S37.

In step S36, it is checked whether or not the currently focused character is currently being displayed on the sub display unit 21. If it is currently displayed, the process proceeds to step S37, and if not, the process proceeds to step S38.
In step S <b> 37, the sub display data generation unit 52 sets and stores character information indicating a space instead of displaying the character at the display position of the currently focused character as the sub display data 77 of the storage unit. (Character non-display setting).
As a result, the character is not displayed on the sub display unit 21. That is, the space is information indicating non-display.
Thereafter, the process returns to step S32 to repeat the same process for the next character.

If the character of interest is currently not displayed in step S36, in step S38, the sub display data generation unit 52 sets the character as the sub display data 77 of the storage unit at the display position of the character of interest. In order to display normally, the character information is set and stored as it is (character display setting).
Thereafter, the process returns to step S32 to repeat the same process for the next character.

In step S34, since the setting storage of the sub display data 77 for all display characters has been completed, the display data stored in the sub display data 77 of the storage unit is displayed on the sub display unit 21. Then, it returns to step S31.
For example, when a display instruction is input as shown in FIG. 3B and an underlined character string is displayed on the main display unit 20, the sub display data 77 for displaying characters belonging to the area specified by the display instruction. Is generated on the sub display unit 21 as shown in FIG.

<Another embodiment of the display control apparatus of the present invention>
Hereinafter, display control of another embodiment of the display control apparatus of the present invention will be described.
Here, after the display instruction is input by the input unit 30, and after a predetermined delay time T has elapsed, the sub display data changed based on the display instruction is displayed on the sub display unit 21. To do.
The predetermined delay time T may be fixedly set in advance. However, when inputting a display instruction, the presenter may be allowed to set and input the delay time T desired by the presenter.
Further, the remaining time until the set delay time T elapses (count remaining time Tc described later) is displayed on the main display unit 20.
In this way, by setting the delay time T, the display information to be displayed on the sub-display unit 21 can be displayed on the sub-display unit by a delay intended by the presenter. The timing at which the display information viewed by the viewer is displayed can be easily adjusted in accordance with the amount and the explanation speed.

FIG. 7 is an explanatory diagram of display information and the like used in another embodiment of the present invention.
FIG. 7A shows an example of display information (content) 73, which is the same as that shown in FIG.
FIG. 7B shows an example of the display control method information 74, and shows the instruction content and display control of the information R3.
The instruction contents of the information R3 are “designate a display character string area A” and “designate a delay time”. As a display instruction, an input of designating a character string area and setting a delay time T is provided. Means to be done.
The display control of the information R3 is “display the character string in the region A after the delay time T has elapsed”, and after an input corresponding to the instruction content of the information R3 is performed as a display instruction, the delay time T set further is set. Means that the character string of the area A is displayed on the sub display unit 21 after the elapse of time.

FIGS. 7C to 7H show examples of changes in the contents of the display instruction information 75 in this other embodiment.
Here, the display instruction information 75 includes a delay time T and a remaining count time Tc in addition to the “designated range” and “designated content” shown in the information 75 of FIG.
The delay time T means the time set in the time input frame displayed on the main display unit 20, as will be described later.
Further, the remaining count time Tc stores the remaining time until time-out when counting the elapse of the set delay time T.
FIGS. 7C to 7H correspond to display screens (a) to (f) of the main display unit 20 shown in FIG.

FIGS. 8A to 8F show an embodiment of a change in the display screen of the main display section 20 in another embodiment of the present invention.
FIGS. 9A to 9F show examples of changes in the display screen of the sub display unit 21 corresponding to FIGS. 8A to 8F, respectively.
FIG. 8A shows a state in which the display information 73 shown in FIG. 7A is displayed on the main display unit 20.
At this time, it is assumed that the display as shown in FIG. That is, it is assumed that only “nuclear energy” and an arrow are displayed, and the third and subsequent lines are not displayed.
Further, in this display state, when the display instruction has not been given yet, it is assumed that the display instruction information 75 is in the initial state as shown in FIG.

Next, it is assumed that the presenter starts inputting a display instruction while viewing the display screen of the main display unit 20 in FIG. For example, as shown in FIG. 8B, it is assumed that the display character string “Nuclear power ... obtained” is traced with a finger. At this time, as the display instruction, the range of the character string traced with the finger is set as the designated range.
That is, as shown in FIG. 7D, “first range, first column to sixth row, ninth column” is set as the “designated range” of the display instruction information 75.
Since there is no underlined character in the display state before the display instruction is input (FIG. 8A), the “designated content” of the display instruction in FIG. 7D is set to “display setting”. The
Further, in FIG. 8B, an underline is added to the character string in the area traced with the finger, and the character string is displayed separately from other character strings. Furthermore, a time input frame for inputting a delay time later is also displayed.
In this case, since the delay time has not yet been input and the display instruction has not been completed, the display on the sub display unit 21 remains the same as that shown in FIG. 9A, as shown in FIG. It is.

Furthermore, it is assumed that the presenter continues to give a display instruction, traces the character string up to the bottom line in FIG. 8A, and completes the designation input of the character string.
FIG. 8C shows a display state in which the character string designation input is completed.
At this time, as shown in FIG. 7E, the “designated range” of the display instruction information 75 is from the first row and the first column to the eleventh row and the ninth column. “Specified content” remains the display setting as in FIG.
Further, as shown in FIG. 9C, since the delay time has not been inputted yet, the display screen of the sub display unit 21 is not changed and is the same as FIG. 9B.

Next, as shown in FIG. 8D, it is assumed that the presenter inputs the delay time T in the time input frame. For example, assume that 10 (seconds) is input as the delay time T.
At this time, as shown in FIG. 8D, the set delay time T (= 10) is displayed in the time input frame.
Also, as shown in FIG. 7F, when the input of the delay time T is completed, the input time (= 10) is stored in the delay time T of the display instruction information 75 and the remaining count time Tc. Then, counting of the delay time T is started.
However, since the delay time has been input, but the delay time T has not yet elapsed, the sub-display unit 21 remains in the same display as in FIG. 9C, as shown in FIG. 9D. .

Thereafter, as the count of the delay time T progresses, the remaining count time Tc decreases. At this time, for example, as shown in FIG. 8E, the remaining count time Tc is displayed in the time input frame. FIG. 8E shows that the remaining time is 5 seconds.
At this time, since 5 seconds have elapsed after setting the delay time T, as shown in FIG. 7G, the remaining count time Tc of the display instruction information 75 is 5 seconds.
Even in this state, since the delay time T has not yet elapsed, the sub display unit 21 remains in the same display as in FIG. 9D, as shown in FIG.

FIG. 8F shows a display state in which the set and inputted delay time T (= 10 seconds) has elapsed. At this time, since the remaining count time Tc becomes zero, the time input frame is deleted.
In FIG. 8F, the part of the character string designated by the presenter by the display instruction is displayed with an underline.
Further, as shown in FIG. 7H, when the delay time T (= 10 seconds) elapses after the delay time is input, the remaining count time Tc becomes zero.
Therefore, since the delay time T has elapsed, as shown in FIG. 9F, a character string designated by the display instruction (designated range = first row, first column to eleventh row, ninth column) as shown in FIG. Is displayed.
Thus, the character string designated by the presenter on the main display unit 20 is displayed on the sub display unit 21 after the set delay time T (= 10 seconds) has elapsed.

  FIG. 10 shows a flowchart of one embodiment of the display control process for main display data in another embodiment of the present invention. This flowchart is executed by the main control program 71.

  In step S51, as in step S1, display information 73 is acquired, main display data generation unit 51 generates main display data 76, and main display data 76 is displayed on main display unit 20.

In step S <b> 52, as in step S <b> 2, the control unit 10 checks whether or not there is an input (character string instruction) meaning a display instruction by the input unit 30.
As described above, a display instruction is input by an explainer performing an input by tracing a desired display character string portion.
If there is a display instruction input, the process proceeds to step S53, and if there is no input, the process returns to step S51.

In step S53, as in step S3, the input display instruction is analyzed, and input position coordinates specifying the position of the display instruction (position of the character string) are acquired.
In step S54, the area A of the character string displayed there is specified from the acquired input position coordinates, and an instruction character string is acquired.
In addition, an underline is added to the acquired instruction character string and displayed on the main display unit 20.
As a result, the character string designated by tracing the presenter is displayed separately from the other character strings.
For example, it is displayed as shown in FIG.

In step S55, a time input frame is displayed on the main display unit 20.
For example, as shown in FIG. 8B, the time input frame may be displayed at an arbitrary position on the display screen of the main display unit 20, and the position may not be fixed.
Further, the size of the time input frame is not particularly limited, and may be a size that allows the presenter to confirm the numbers displayed in the frame.

In step S56, it is checked whether or not a delay time has been input in the time input frame.
The presenter may directly input a numerical value corresponding to the delay time T using a keyboard or the like, or may select and input a numerical value displayed on the touch panel.
If the delay time T is input, the process proceeds to step S57, and if not, the process returns to step S51.

In step S57, the input time (numerical value) is stored in the storage unit 70 as the delay time T. The value of the delay time T is set as the remaining count time Tc. Further, the delay time T is displayed in the time input frame of the main display unit 20. For example, the display as shown in FIG.
In step S58, a 1 second timer is started. The timer does not have to be 1 second, and may be any timer that counts a reference time.
In step S59, it is checked whether or not the 1-second timer has timed out. If not timed out, step S59 is looped. If timed out, the process proceeds to step S60.

In step S60, 1 is subtracted from the remaining count time Tc (Tc = Tc-1).
The count remaining time Tc after subtracting 1 is displayed in the time input frame. For example, a display as shown in FIG.
In step S61, it is checked whether or not the delay time T set and input has elapsed, that is, whether or not the remaining count time Tc has become zero.
If Tc ≠ 0, the process returns to step S58, and if Tc = 0, the display of the time input frame is deleted and the process returns to step S51.
Thereby, the identification display (underlined display) of the designated character string on the main display unit 20, the input of the delay time T, and the countdown display are performed.

  Through the above processing, the display data stored in the main display data 76 is displayed on the main display unit 20 in the order shown in FIGS. 8A to 8F, for example.

FIG. 11 shows a flowchart of one embodiment of the display control process of the sub display data in another embodiment of the present invention. This flowchart is executed by the sub-control program 72.
In step S71, as in step S31, the control unit 10 checks whether or not a new display instruction has been input.
If there is a new input, the process proceeds to step S72. If there is no input, or even if there is an input, the display instruction is the same as the previous one and there is no change, step S71 is looped.

In step 72, it is checked whether or not the delay time T has elapsed. That is, it is checked whether or not the remaining count time Tc = 0.
If Tc = 0, step S72 is looped. When Tc = 0, since the set delay time T has elapsed, the process proceeds to step S73.

In step S73, the instruction character string at the position input by the display instruction is acquired.
For example, the character string displayed on the main display unit 20 as an underlined character string traced with a finger is acquired.
In step S74, it is checked whether or not the instruction content of the display instruction information 75 is “display setting”.
If it is “display setting”, the process proceeds to step S75, and if it is “non-display setting”, the process proceeds to step S76.

In step S75, the character information is set and stored in the display position of the acquired instruction character string as the sub display data 77 of the storage unit 70 so that the instruction character string is displayed on the sub display unit 21.
In step S77, the display data stored in the sub display data 77 of the storage unit is displayed on the sub display unit 21. Thereby, for example, the display as shown in FIG. 9F is performed on the sub display unit 21 in correspondence with the display of the main display unit 20 of FIG.

On the other hand, in step S76, in order to hide the instruction character string, character information indicating a space is set and stored in the display position of the acquired instruction character string as the sub display data 77 of the storage unit. Thereafter, the sub display data 77 is displayed on the sub display unit 21 in step S77.
In this case, for example, a display as shown in FIG.
After step S77, the process returns to step S71.

Thereby, the display data stored in the sub display data 77 of the storage unit is displayed on the display screen of the sub display unit 21, and the instruction character string is displayed or hidden based on the display instruction.
For example, a display screen as shown in any of FIGS. 9A to 9F is displayed on the sub display unit 21.
Therefore, the viewer who uses the sub display unit 21 sees the display content based on the display instruction intended by the presenter.
In addition, as shown in FIGS. 8A to 8F, the presenter displays the display content on the main display unit 20 based on the display instruction input by himself / herself. , It is possible to easily confirm what display content the viewer is currently viewing.
