Furthermore, the drawing control unit 4 temporarily converts the read screen information into two-dimensional format pixel data into a frame memory 5.
The information is stored in the CRT 7 and output as table or display screen information for display.

[Problems to be Solved by the Invention] Since the conventional presentation device is configured as described above, during a presentation, some images (images used for explanations, etc.) are displayed based on a scenario such as the display order. Therefore, even if the presenter wants to draw the audience's attention to his or her verbal explanation, the viewer's attention may be lost to the displayed image. In addition, when presenting using OHP, attention is being paid to methods such as not placing an OHP sheet, placing cardboard, etc., and turning off the power, but especially when using electronic presentation means (conventional presentation devices), Information such as "not to be displayed" had to be set in the scenario itself, which caused issues such as a lack of flexibility in presentations.

This invention was made in order to solve the above-mentioned problems. During a presentation, for example, by displaying blank screen information (hereinafter referred to as specific screen information), it is possible to attract the attention of the audience. It is an object of the present invention to obtain a presentation device that can attract a presenter and use the function independently of a scenario.

[Means for Solving the Problems] A presentation device according to the present invention includes a first frame memory and a second frame memory in a display control unit, and an analysis drawing unit that inputs data from a screen information storage unit to the first frame memory. The read screen information for the presentation is drawn, specific screen information is drawn in the second frame memory, and the switching processing unit draws the read screen information for the presentation, draws specific screen information in the second frame memory, and according to the instruction output by the analysis drawing unit that received the instruction from the outside. This allows you to switch the screen information to be output.

[Effect]

The display control unit in the present invention includes a first frame memory that stores screen information to be displayed and a second frame memory that stores specific screen information, and outputs screen information in the switching processing unit at an arbitrary timing. Since switching is possible, it is possible to smoothly interrupt and resume image display based on the scenario.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a presentation device according to an embodiment of the present invention, and the same or equivalent parts as in the conventional presentation device (FIG. 2) are given the same reference numerals and their explanations will be omitted.

In the figure, 8 reads out the corresponding screen information from the screen information storage section 1 according to the display order information stored in advance in the display order storage section 2, draws it in the first frame memory 9a, and also draws specific screen information. An analysis/drawing section draws in the second frame memory 9b and instructs the switching processing section 10 to switch according to instructions from the keyboard 3; 9a and 9b are the first and second frame memories, respectively; 10 is the first and second frame memory; This is a switching processing section that switches and outputs the screen information stored in the frame memories 9a and 9b of the frame memories 9a and 9b according to instructions from the analysis and drawing section 8, and the analysis and drawing section 8, the first and second frame memories 9a, 9b and the switching processing section 10 constitute a display control section 11.

Next, the operation will be explained.

The analysis/drawing section 8 draws specific screen information in advance in the second frame memory 9b, and also draws the corresponding screen information from the screen information storage section 1 in accordance with the display order stored in advance in the display order storage section 2. The data is read out and drawn in the first frame memory 9a.

In the case of normal display, the analysis/drawing section 8 instructs the switching processing section 10 to switch to output the screen information stored in the first frame memory 9a;
The CRT 7 is displaying the screen information output from 0.

During a presentation, if the presenter wants to draw the attention of the audience to himself, he inputs an instruction to interrupt the display from the keyboard 3. When the analysis and drawing section 8 receives this display interruption instruction, the analysis and drawing section 8 switches the screen information output from the switching processing section 10 to output the specific screen information stored in the second frame memory 9b. print instructions,
The specific screen information output from the switching processing section 10 is
RT7 displays. Further, when restarting the display, the presenter inputs a display restart instruction again from the keyboard 3. When the analysis and drawing section 8 receives this display restart instruction, the analysis and drawing section 8 outputs a switching instruction to the switching processing section 10 to output the screen information stored in the first frame memory 9a, and - The CRT 7 displays the screen information output from the switching processing section 10.
