Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called presentation system or the like for giving a lecture, a presentation, or an explanation, for example, using images projected or projected on a relatively large screen for a relatively large number of people. The present invention relates to a display device suitable for application to.

[0002]

2. Description of the Related Art Conventionally, for example, as a so-called presentation system for giving a lecture, presentation, or explanation using images projected or projected on a relatively large screen for a relatively large number of people, for example, as shown in FIG. There is one as shown in 5.

The presentation system shown in FIG. 5 is generally called an overhead projector (OHP), and this overhead projector is an OHP sheet in which light from the light source 2 of the OHP main body 1 is placed on the OHP main body 1. Irradiate 3 and this OHP sheet 3
The light transmitted through is reflected by the mirror 4, and the reflected light is projected on the screen 6 by the optical lens 5.

An image to be projected on the screen 6 is printed or printed on the OHP sheet 3 in advance. Generally, for example, a document created by a word processor, a document created by a computer or the like, a figure, or image data once read by an image reader or the like is printed out by a printer, and the printed out copy is copied to the OHP sheet 3. I am trying.

[0005]

By the way, as described above, it takes a lot of time and effort to copy an image onto an OHP sheet to create a material for a presentation, and in general, a large number of OHP sheets are required to give a presentation. Therefore, it takes a huge amount of time to create a material for one presentation.

During the presentation, many OHP sheets are used for the purpose of presentation.
Or, it is quite difficult to make sure that the program follows smoothly. For example, when giving a presentation by one person, it is necessary to set the OHP sheet by himself while explaining, so it is not the OHP sheet corresponding to the explanation at that time, and the OHP sheet to be used in other explanations.
There is an inconvenience that a smooth presentation cannot be performed due to the work of setting the sheet or picking up the OHP sheet by hand and then setting it on the device such as the above-described overhead projector.

Further, the OHP sheet used for one presentation or the OHP sheet used a plurality of times for a common purpose is rarely used again, and most of them are discarded at present. Yes, it is very problematic from the viewpoint of resource issues.

The present invention has been made in view of the above points, and a display capable of smoothly and reliably giving a presentation, simplifying the preparation of materials for presentation, and contributing to resource saving. It is intended to propose a device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the display device of the present invention will be described in detail below with reference to FIG.

In FIG. 1, 10 is a CPU, 11 is a bus consisting of data, address and control buses, 12 is a ROM in which programs and the like to be described later with reference to FIGS. 3 and 4 are stored in advance, and 13 is program processing. It is a RAM for the work and for storing data having a large amount of information such as image data.

Reference numeral 14 is an image input interface (IF)
For example, a video camera, an image scanner, an electronic still camera, and the like (not shown) are connected in the circuit, and image data obtained by picking up images of materials used for presentation by these electronic devices is taken in and RA is given, for example, via the bus 11.
It is for storing in M13. Reference numeral 15 is an image output interface (IF) circuit, which is R via the bus 11.
The image data supplied from the AM 13 is displayed on the large screen monitor 17
To be displayed on the display surface or projected on the tube surface.

A driver 16 drives a large screen monitor 17 to display the image data from the image output interface circuit 15 on its display surface. here,
As the large screen monitor 17, for example, a liquid crystal display,
Any display device such as a front or rear projection type display or a CRT display may be used. In the case of FIG. 1, for example, when a liquid crystal display, a front or rear projection type display is used, the driver 16 is required, but when a CRT display is used, the output of the image output interface circuit 15 is the large screen monitor 17. Can be directly connected to.

A disk driver 18 records, for example, image data fetched through the image input interface circuit 14, data created by various programs operated by the CPU 10, such as word processor software, or various data used for presentation. It is for doing. As a disk to actually use,
For example, a floppy disk, a hard disk (including a fixed type or a floppy disk which can be freely taken out from a drive), a magneto-optical disk, a floppy disk, a silicon disk (actually a semiconductor memory device), etc. are not particularly limited.

Reference numeral 19 is a matrix switch, that is, a film switch arranged in a matrix. As will be described later, in this example, the matrix switch 19 is shown in FIG.
Stick it on the tube surface of the monitor 23 as shown.
Moreover, a plurality of image data are divided and displayed on the tube surface corresponding to each switch of the matrix switch 19, and when the switch of the matrix switch 19 is turned on, the corresponding image data is selected and the above-mentioned large image data is selected. Screen monitor 17
Displayed on the display surface or projected on the tube surface (for convenience of explanation,
From now on, only display on the display surface will be described).

Reference numeral 20 is a keyboard, and 21 is a mouse.
Since the trackball is basically regarded as the same as the mouse, its illustration and description are omitted.

Next, a system image of the display device shown in FIG. 1 will be described with reference to FIG. 2, parts corresponding to those in FIG. 1 are designated by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 2, reference numeral 25 denotes an apparatus main body housing, which houses, for example, the circuit shown in FIG. By the way, as the apparatus main body, for example, a workstation or a personal computer can be used. In this case, the image input interface circuit 14 and the image output interface circuits 15 and 22 shown in FIG. You may make it insert in a slot.

Further, as shown in this figure, the area on the tube surface of the monitor 3 is divided into a divided image data display area 26a (in a grid in the figure) and a selection or command input area 2 is formed.
6b, and further divided image data display area 26
Image data set by the user in advance can be displayed in a. This example shows an example in which image data of people, circles, squares, and triangles are displayed in order from the left on the tube surface of the monitor 3.

In addition, a selection or command input area 2
Although not shown in FIG. 6b, for example, the keyboard 20
The commands that can be specified with the or mouse 21 are displayed. As will be described later, these commands include page turning, large screen display, end, automatic presentation, voice output, and the like. Page down 1 page 1
It becomes very convenient by introducing the concept of page when there is a lot of image data as image data for a screen.

The large-screen display will be described later, but the matrix switch 19 corresponding to the image data displayed on the monitor 23.
Is a command for designating whether to display the selected image data on the large screen monitor 17 when the switch sw is turned on. End is a command for executing the end of the presentation. The automatic presentation is, for example, a command for automatically executing commands such as image data selection, page feed, large screen display, end, and audio output, according to preset parameters. The voice output is a command that designates whether or not to output the voice data recorded as a file in advance.

Then, each switch sw of the matrix switch 19 is made to correspond to each divided image data display area 26a. As a way of dealing with it, the monitor 23
The switch sw of the matrix switch 19 is positioned within the range of each divided image data display area 26a on the tube surface, and the switch and the source of the image data displayed in the divided image data display area 26a. The data may be stored, or a table may be provided to correspond the recording addresses.

That is, in the figure, when the switch sw corresponding to the divided image data display area 26a displaying the image data m1 of a person is turned on, the image output interface circuit 15, the driver 16 and the image output interface circuit 15 shown in FIG. The disk set in the disk driver 18 or the corresponding image data m2 stored in the RAM 13 is supplied to the large screen monitor 17 via the cable 27 shown in FIG.
An image is displayed on the display surface.

In the example shown in this figure, for example, when the image data m1 of a person displayed in the divided image data display area 26a on the tube surface of the monitor 23 is turned on by the corresponding switch sw of the matrix switch 19. The image data m2 which is the source of the selected image data m1 is displayed on the large screen monitor 17.

Next, the operation of the display device shown in FIGS. 1 and 2 will be described with reference to FIGS. This Figure 3
The program shown in the flowchart in Figure 1 creates graphs, images, character files, etc. necessary for the presentation, combines several created files into one, converts the format so that it can be used in the actual presentation, and prepares the presentation. Is for doing.

First, in step S1, initial setting is performed. Then, the process proceeds to step S2. This initial setting means that one or a plurality of file names (files of graphs, images, characters, etc. created in advance) are assigned to the keyboard 20 and the mouse 21.
Is to enter.

In step S2, a file is loaded. Then, the process proceeds to step S3.

In step S3, the imported file is edited. Then, the process proceeds to step S4. That is, for example, the number of screens to be displayed on the screen of the monitor 23 is determined by the input from the keyboard 20 or the mouse 21, and the respective image data are displayed in the divided image data display area 26a described in FIG. It is reduced by thinning out and stored in the RAM 13 shown in FIG. 1 in the order of presentation. The order of presentations can be specified with the keyboard 20 and the mouse 21.

That is, the number of screens to be displayed on the screen of the monitor 23 by the user performing an operation of reducing and displaying the data of the file created in advance on the screen by operating the keyboard 20 and the mouse 21. , Original file name of each screen and switch of matrix switch 19
Data indicating the correspondence of w and the like is generated. Incidentally, for example, in FIG.
A voice input interface circuit is added to record the voice data as a file, and the switch s of the matrix switch 19 together with the file of the image data and the like is added.
You may make it correspond to w.

In this case, in addition to the audio output interface circuit in FIG. 1, a device for audio amplification (pre-main amplifier) and a speaker are added, or
Alternatively, the large-screen monitor 17 may have a built-in speaker and audio output circuit. If you output audio corresponding to the video, for example, in the case of animal video, you can output its cry to enhance the effect of the presentation, or output audio for explanation automatically when the corresponding video is output. It is possible to obtain various effects such as making an unattended presentation.

In step S4, as described above, data indicating the number of screens to be displayed on the screen of the monitor 23, the original file name of each screen and the correspondence between the switch sw of the matrix switch 19 and the like is stored as a file in a disk, for example. The data is recorded on the disc set in the driver 18. And it ends. Hereinafter, the file created here is referred to as an executable file.

By the way, there are roughly two methods for creating an execution file. One is a method of saving only the file name of the original image data as the data of the execution file. In this case, when actually displaying each image data on the monitor 23, for example, a file of each image data is sequentially read, and thinning (by software or hardware) is performed in real time, and the thinned image data is stored in the RAM 13. To the RAM13 one by one
Screen portion (actually the selection or command input area 26
After the writing of the image data of the area excluding b) is completed, the RAM 13 is read and the image data is displayed on the monitor 23.

In another method, a plurality of image data are reduced in advance, one reduced image data screen is recorded as one page file, and the page file name and the file names of the plurality of image data are recorded. This is a method of recording as an execution file. In this case, when actually displaying each image data on the monitor 23, for example, a file in which one screen of reduced image data is recorded as one page file is sequentially read and sequentially written in the RAM 13, and one screen is recorded in the RAM 13. After the writing of the image data of the area (actually the area excluding the selection or command input area 26b) is completed, this RAM
13 is read out and the image data is displayed on the monitor 23.

Next, the operation in the presentation will be described with reference to the flowchart of FIG. The program shown by the flowchart in FIG. 4 is for reading the execution file created in step S4 of the flowchart shown in FIG. 3 and then for giving a presentation according to the data of the read execution file.

First, in step S10, a menu is displayed. Although not shown, the menu displayed here is like a list of execution files. The user uses the keyboard 20 or the mouse 21 to select a desired execution file on this menu.

In step S11, the execution file selected by the user in step S10 is read from the disk of the disk driver 18 shown in FIG. 1, for example. Then, the process proceeds to step S12.

In step S12, the disk driver 18
As shown in FIG. 2, the corresponding image data is displayed in the divided image data display area 26a on the tube surface of the monitor 23 in accordance with the execution file read from the disk set in the. Then, the process proceeds to step S13.

In step S13, the input is awaited. This input waiting is a mode of waiting for the switch sw of the matrix switch 19 attached on the tube surface of the monitor 23 to be turned on, as described with reference to FIGS. 1 and 2. Then, the process proceeds to step S14.

In step S14, it is determined whether or not there is an input, and if "YES" is determined, step S14
If the determination is "NO", the process proceeds to step S13 again.

In step S15, it is determined whether or not the page is turned. If "YES", the process proceeds to step S17, and if "NO", the process proceeds to step S16. In other words, the image data specified in the execution file may not fit in one screen, so the concept of page is introduced in this example. If the page is designated, the image data of the page can be displayed on the screen of the monitor 23. Therefore, for example, even if a large amount of image data is designated, it can be dealt with.

In step S17, page turning is performed. Then, the process proceeds to step S13 again. That is, when the user specifies page turning with the keyboard 20 or the mouse 21, the page is advanced (or returned) in response to the operation. Then, the image data of the page is displayed on the monitor 23.
Display on the tube surface of.

In step S16, it is determined whether or not a large screen is displayed. If "YES", the process proceeds to step S19,
If “NO”, the process proceeds to step S18.

In step S19, a large screen display is performed. Then, the process proceeds to step S14 again. That is, step S
In 16 the user has a keyboard 20 or mouse 21
When a large screen display is designated by using, the original file of the image data corresponding to the switch sw of the matrix switch 19 that is turned on is read from, for example, the disk set in the disk driver 18, and the read image data is read. Image output interface circuit 15, driver 1
It is supplied to the large screen monitor 17 via 6 and displayed as an image on its display surface.

In step S18, it is determined whether or not the process is finished,
If "YES", the process ends, and if "NO", the process proceeds to step S20. That is, when the user selects the end using the keyboard 20 or the mouse 21, the process ends.

In step S20, it is determined whether or not another process is performed, and if "YES", the process proceeds to step S21 and "N".
If it is "O", the process proceeds to step S14 again. As this other processing, for example, the above-described automatic presentation, audio output, and the like are performed.

As described above, in this example, the images, graphs, character data, sounds, etc. to be used in the presentation are recorded as a file, and the number of screens to be displayed on the screen of the monitor 23 and the source of each screen are recorded. Data indicating the correspondence between the file name of the above and the switch sw of the matrix switch 19 is recorded as an execution file,
The recorded execution file is read and a plurality of reduced (or reduced) image data are output on the tube surface of the monitor 23, and the switch sw of the matrix switch 19 attached to the tube surface of the monitor 23 is turned on. At this time, the original image data of the corresponding image data is read from the disk driver 18 and displayed on the large screen monitor 17, so that the presentation can be performed smoothly and surely and the presentation material can be used. Can be simplified, and can contribute to resource saving unlike the overhead projector.

When the image data, which is the source of the reduced image data recorded on the disc set in the disc driver 18, is accessed according to the data of the execution file at the time of presentation,
High-speed access cannot be expected although it depends on the recording medium. Therefore, the RAM 13 shown in FIG. 1 is made to have a large capacity, all the original image data used in the presentation is read out immediately before the presentation, and this is read in the RAM 1
3 and the switch sw of the matrix switch 19 from this RAM 13 at the time of presentation thereafter.
If the image data corresponding to is read out and displayed on the large-screen monitor 17, the access speed is improved, so that the presentation can be performed smoothly.

Further, since it is costly to make the RAM 13 large in capacity, for example, the RAM 13 is provided with an area for at least two screens, that is, a first area and a second area, and first, just before the presentation. 1 in the area
The image data to be displayed on the large screen monitor 17 is stored second, the image data to be displayed on the large screen monitor 17 second is stored in the second area, and after the presentation is started, access to the first area is completed. Then, when the second area is being accessed, the third large screen monitor 17
The image data to be displayed on is stored in the first area,
If the same process is repeated thereafter, the memory 1
The access speed can be improved even if 3 is not a large capacity one. However, in this case, the output order of the image data is determined in advance, and the person giving the presentation randomly selects the reduced image data displayed on the screen of the monitor 23 for the convenience at that time. Then
It is difficult to use when displaying on the large screen monitor 17.

In this case, for example, pre-compressed image data is collectively recorded, and at the time of presentation, all the compressed image data is stored in the RAM 13 as it is, and the compressed image data designated when the large screen display is designated is expanded. Then, the original image data can be obtained and displayed on the large screen monitor 17. If you do this,
The access speed can be improved as compared with accessing from the disk.

Further, in the above example, the case where the command displayed in the selection or command display area 26b is selected by the keyboard 20 or the mouse 21 has been described, but by touching with a finger using the matrix switch 19, for example. Command selection may be possible. In this case, the device can be made easier to use.

In the above example, when the matrix switch 19 is attached on the tube surface of the monitor 23 and the image data corresponding to the switch sw of the matrix switch 19 is selected by directly touching it with a finger. As described above, an arrow figure (referred to as a pointer or the like) is projected on the screen and is displayed on the keyboard 20 for example.
Alternatively, the image data may be selected by moving the mouse or the mouse 21 and pressing or clicking the return key at a desired position on the image data. In this case, since the matrix switch 19 is not needed, the device can be simplified.

Further, in the above example, the case where the image data to be used is reduced and displayed on the monitor 23 as it is has been described. However, for example, the image data displayed on the monitor 23 is the original image data. It may be a character or symbol to indicate. In this case, the processing is simpler than in the case where the image data is reduced and directly displayed, so that the device configuration or the program can be simplified.

As means for performing the above processing, for example, even if a processing program is installed from a floppy disk to a disk (preferably a hard disk) of the disk drive 18, the disk drive 18
Alternatively, the disk may be a floppy disk and the program recorded on the floppy disk may be executed.

Further, in the above-mentioned example, the case where the presentation is performed by one apparatus main body has been described, but for example, a plurality of apparatus main bodies are installed in different rooms, and the main apparatus installed in these different rooms is explained. A main unit of the main unit and a terminal unit having only a plurality of memories are connected by a local area network (LAN), etc., and the main unit main unit transmits the processing program to the plurality of terminal units, and the main unit and The programs may be executed on a plurality of terminal devices, respectively, so that different presentations may be performed simultaneously in each room.
In such a case, it is not necessary to use a disk drive or the like for the terminal device, so the cost per unit can be significantly reduced, and for example, the main device main body can be made to have all image data in a database. There is an advantage that this can be shared by a plurality of terminal devices.

The above-described embodiment is an example of the present invention, and it goes without saying that various other configurations can be adopted without departing from the scope of the present invention.
