Description

Description: TECHNICAL FIELD The present invention relates to an image creating / editing apparatus having a disk image processing function, and particularly to drawings and photographs used for so-called presentations at conferences and lectures. And an electronic presentation system having a display function of image data such as sentences.

<Prior Art> Conventionally, an image display device used for a presentation includes an overhead projector that magnifies and projects an image on a film by an optical method, and a slide projector that projects an image of a slide film on a screen by light of an optical lamp. , A combination of a video camera and a video monitor. However, since the images written on each film are displayed as they are on the overhead projector and the slide projector, it takes a lot of time and effort to prepare a document when an excellent looking image is to be obtained. Further, for the same reason, it is difficult to perform dynamic display such as movement and change of an image, and it is not possible to perform effective display. Further, the number of screens is limited to one and the luminance is low Therefore, in the case of a presentation for a large number of people, there are disadvantages such as difficulty in displaying a satisfactory image.

Therefore, as a means of presentation in a meeting room, etc., a display image of instruction information is created by image generation technology or image processing technology using a computer, and this image is displayed on a large projector or a display for a lecturer. Information display devices have been proposed. This apparatus uses digital image processing technology to create in advance data of a display image and data relating to a process of changing an image being displayed, and to generate image data based on the prepared display image data. It is created and displayed on a large projector or a speaker display, and the displayed image is changed based on data relating to the image changing process. Therefore, as compared with the above-mentioned overhead projectors and slide projectors, various images can be displayed and changed, dynamic images can be displayed, and the like, and there is an advantage that a good-looking image can be displayed.

<Problems to be Solved by the Invention> However, the above-mentioned conventional image information display device using a computer simply unilaterally displays an image for a listener on a large-sized projector, or displays an image for an audience on a monitor. The speaker is speaking at the speed
It is possible to know during the lecture that the loudness and posture of the voice are appropriate for the listener, and that the display contents such as the screen size, brightness and color are easy for the listener to see. The problem is that the disadvantages of the lecture cannot be fixed during the lecture.

Therefore, an object of the present invention is to evaluate a speaker's speaking speed, posture, loudness of voice, or brightness, color, size, etc. of an image displayed on a large projector to a third party during a lecture. Another object of the present invention is to provide an image information display device capable of displaying the evaluation message on a monitor for a speaker.

<Means for Solving Problems> In order to achieve the above-mentioned object, the present invention reads the image display data stored in the nonvolatile external memory by the reading means, and the listener image data by the image data generating means. Stored in the first image data memory,
In an image information display device for displaying an image on the image display for listeners based on the stored image data for listeners, a transmitter for transmitting a message from a third party to a speaker, and a transmitter for transmitting the message. When the message is received, the image data generation means requests the image data generation means to generate message image data composed of image data or character data, and the image data generation means generates the image data according to the request from the reception means. A second image data memory for storing the stored message image data, and a mixer for synthesizing the listener image data stored in the first image data memory and the message image data stored in the second image data memory , Display images for speakers using the image data synthesized by the above mixer It is characterized by comprising an image display means for performers.

<Operation> When the non-volatile external memory storing the data for image display is set in the reading means, the data for image display is read by the reading means and converted into the image data by the image data generating means. The personal image data is stored in the first image data memory. Then, the image for the listener is displayed by the image display for the listener based on the stored image data for the listener.

At that time, when the message from the third party is transmitted to the speaker by the transmitting means and this message is received by the receiving means, the receiving means receives a message image including image data or character data representing the received message. Generation of data is required of the image data generating means. Then, the message image data generated by the image data generating means in accordance with the request from the receiving means is stored in the second image data memory.

Then, the image data for listeners stored in the first image data memory and the message image data stored in the second image data memory are combined by the mixer, and the combined image data is used to give a lecturer. The image for the speaker is displayed by the speaker image display means.

Therefore, the lecturer can know the message from the third party by seeing the screen of the lecturer image display means.

<Example> Hereinafter, the present invention will be described in detail with reference to illustrated examples.

In FIG. 1, a CPU (central processing unit) 1 controls the entire image information display device (hereinafter referred to as the present device), performs image generation and image change processing, etc., and is read by a floppy disk device 2 described later. According to the instruction code string output via the interface 5, the first image memory 3
Alternatively, the image data is written in the second image memory 7.

The floppy disk device 2 is a data reading means and reads the data of the instruction code string from the floppy disk which is a non-volatile external memory. This instruction code string is edited and created based on the image information and the display change processing information by an image editing device (not shown) provided separately from the present device. The floppy disk device 2 is connected to the CPU 1 via the interface 5 and the system bus 6.

The first image memory 3 has an image display function, stores image data to be displayed, and generates a video signal corresponding to the image data. By this video signal, an image is displayed on the large-sized projector 4 having a large screen of 100 inches, which is an image display means for listeners. The large projector 4 may be a color CRT (cathode ray tube) monitor or a configuration using a plurality of these monitors. The first image memory 3 is the CPU 1 via the system bus 6.
Connected to

The second image memory 7 has an image display function similarly to the first image memory 3, stores the message image data obtained from the message sent from the message transmission device 15 and received by the receiver 11, and at the same time, stores the message. A video signal corresponding to the image data is generated. Therefore, the second image memory 7 only needs to display a small number of characters or a simple graphic, has a smaller number of bits per pixel than the first image memory 3, and can express a gradation or a color. A small number is enough. The second image memory 7 is connected to the CPU 1 via the system bus 6. The mixer 8 synthesizes the video signals generated from the first image memory 3 and the second image memory 7 and outputs them to the monitor 9 which is the image display means for a speaker, which will be described later. The monitor 9 is provided on the operator's console 12 as shown in FIG. 2, and its screen is the same as the display image of the large projector 4 due to the composite video signal input from the mixer 8. An image on which an image based on the image data stored in the second image memory 7 is superimposed is displayed on the image. The superimposition form of these two images has an attribute that the background of the image from the second image memory 7 is transparent,
It is obtained by displaying the display image of the large-sized projector 4 on this background portion. Also, on the console 12 above,
As shown in FIG. 2, a microphone 13 for a speaker, a floppy disk device 2, and a switch 14 for starting and stopping the device are provided.

The receiver 11 converts the weak radio wave received by the antenna 19 into a code, and when receiving the code from the message transmitting device 15, requests the CPU 1 for an interrupt process and a process for displaying a message. Then, the data converted into the code is converted into the message image data by the CPU 1 and stored in the second image memory 7. FIG. 3 shows the message transmitting device 15. Keyboard 18
When a particular third party sends a lecturer's way of speaking and a message on the screen displayed on the large-sized projector 4 to the lecturer, a code representing the message is input. The code input from the keyboard 18 is FM-modulated by the receiver 16 and then transmitted as a weak radio wave from the antenna 20. Further, as shown in FIG. 4, the message transmitting device 15 is of a compact handy type so that a specific third person can carry it around freely. The specific third party mentioned here is the person who listens to the lecture and points out the points that should be corrected and evaluated as good or bad.

 The image information display means having the above configuration operates as follows.

The specified third party holds the message transmission device 15 and listens to the lecture with the listener or at a place different from the listener. Then, the keyboard 18 is input from time to time with respect to how the speaker speaks or the screen to be displayed should be improved. In this embodiment, the contents to be improved that can be input are the "speaking speed", "loudness", and "brightness / darkness of the screen" of the speaker, as shown in FIG.
Two improvement methods are set for each of the contents, and a code is associated with each of them. For example, when a specific third party evaluates that the speaker's voice is low and transmits an instruction to increase the voice, the code “Vl” is input from the keyboard 18 of the message transmitting device 15. This code is FM-modulated by the transmitter 16 and then sent from the antenna 20 to the image information display device as a weak radio wave. Image information display device antenna
When this code is received at 19, an interrupt request is issued to the CPU 1, and processing for displaying a message corresponding to the received code is requested. Here, on the screen of the monitor 9, the image of the message image data is superimposed on the image for the listener as described above, and the way the speaker speaks or the image is displayed on a part of the screen as shown in FIG. The image in which the improvement item is displayed is displayed. At this time, the image shown in FIG. 7 is displayed on the large-sized projector 4 for listeners. The CPU 1 receives the above code, and in order to display the message on the monitor 9 for the speaker, does the following. That is, when the CPU 1 receives the code "Vl" to make the voice louder, the CPU 1 changes the color of the portion "loud voice" of the message image displayed on the monitor 9 to instruct the speaker to make the voice louder. Let us know that there was This is realized by rewriting the color of the improvement item column of the second image memory 7 in accordance with a command from the CPU 1. At this time, the color of the improvement item column of the image memory 7 is rewritten not only once but also repeatedly, and the improvement item column of the screen is displayed in a blinking manner. It is possible to call further attention. In this way, the color of the column of "loud voice" changes, so the speaker's own voice is small,
The listener can understand that he / she is not hearing enough, and can continue the lecture while being careful to give a loud voice thereafter.

In this embodiment, messages other than those shown in FIG. 5 are transmitted by directly typing characters on the keyboard 18. The characters that have been typed in are converted into character codes and sent from the transmitter 16 to the image information display device, and the weak radio waves received by the receiver 11 are converted into character codes again, and the CPU 1 uses image data corresponding to the character codes. Is written in the second image memory 7 and displayed on the monitor 9 for the speaker. For example, when a particular third person types in "the graph is wrong" from the keyboard 18, a message 22 "The graph is wrong" is displayed on the screen of the monitor 9 as shown in FIG. In this way, an appropriate message for the lecture can be externally displayed on the monitor 9.

In the above embodiment, the transmitter and receiver of weak radio waves by FM are used as the message transmitting and receiving means. But,
A near-infrared LED (light emitting diode) and a phototransistor which is a light receiving element thereof may be used.

<Effects of the Invention> As is clear from the above, when the message from the third party to the lecturer is transmitted by the transmitting means, the image information display device of the present invention is the image data generating means by the receiving means that receives the message. Request generation of message image data to the second image data memory, the message image data generated by the image data generating means in accordance with the request is stored in the second image data memory, and the listener image stored in the first image data memory is stored. The speaker image is displayed by the speaker image display means by using the image data obtained by synthesizing the data and the message image data stored in the second image data memory by the mixer, ,
By looking at the screen displayed by the speaker image display means, the message from the third party can be known, and the message can be dealt with immediately.

Therefore, according to the message from the third party, it is possible to give a lecture with an optimal volume of voice, posture, and state of the image for listeners.
