Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device which electronically displays an image based on a predetermined execution procedure using a medium on which a plurality of images are recorded.

[0002]

2. Description of the Related Art Characters, voices, images, etc. are generally used as a medium for transmitting information, but it is difficult for a computer or the like to handle an image having a huge amount of data as digital data. Met. However, with the recent advances in computer technology and the increase in capacity of recording media, devices for accumulating and reproducing images have continued to evolve.
In the field of handling still images, recently, in addition to simply accumulating images, images are successively reproduced with a specific storyline, or interactive (Interactive) with a person who uses the device. It has become possible to replay it, and it is being developed in various fields including presentations.

This image display device compresses a natural image or a character / graphic image, or an image created by a combination of these images, if necessary, and then performs processing such as data compression on an optical disk or the like. It has a function of pre-recording on a large-capacity recording medium, reading an image at high speed during reproduction, and displaying it on a display device. Also,
Some have a function that can add a special visual effect to the switching operation at the time of displaying an image, which improves appeal.

In order to realize continuous reproduction or interactive reproduction of images having a story as described above, display control data (scenario) describing a reproduction procedure is necessary. In this scenario, a medium on which an image is recorded or a dedicated medium is prepared and recorded in advance.

The amount of image data varies greatly depending on the size and resolution, but is usually several kbytes to several Mbytes. Since a recording medium such as an optical disk has a recording capacity of several hundred megabytes, it depends on whether data is compressed or not.
Thousands of image files can be recorded. Therefore, prepare a plurality of the above-mentioned scenarios and select and use them. Further, in the case of realizing the interactive reproduction, a case where one scenario is called to another scenario or branched is considered.

An image display device using such display control information is disclosed in, for example, Japanese Patent Laid-Open No. 62-1520.
In the publication, a presentation system is provided in which a document file to be presented and a control information file are recorded on a medium, and when the document is presented, the presentation of the document to the presenting means is controlled according to the control information described in the control information file. Things are disclosed.

[0007]

A recording medium such as an optical disk has a large recording capacity and is suitable for use in recording a large amount of data such as an image. On the other hand, there is a problem that access is slower than that of magnetic recording media.

On the other hand, as described in the section of the prior art, in an image display device which reproduces an image in a specific procedure, a scenario describing the reproduction procedure is created and recorded on a medium in the same manner as the image. ing. For this reason, since a scenario reading operation is added from the start of the reproduction operation until the first image is displayed, a waiting time occurs. The larger the scenario file, the longer the waiting time, which increases the psychological burden on the user. Alternatively, when a branch operation to another scenario as described above is included, a waiting time occurs and a similar problem occurs.

Thus, considering that the data amount of an image is enormous and that not only the image but also the display control data is read out, an access method and a data management method are required to realize smooth reproduction. It is necessary to devise. There are some conventional image display devices that reduce the read time by compressing images with a large amount of data, but there is a wait time due to the scenario file read operation. Was not considered.

In addition to the above problems, there are the following problems in creating scenario data. An image display device that reproduces an image according to a scenario requires a tool for creating scenario data, and it is desirable for a user to be able to create a scenario efficiently with a simple operation. Scenarios are often composed of text data. Therefore, developing a scenario creation tool is equivalent to developing a kind of editor, and the development burden is heavy.

The present invention has been made in view of the above problems, and an object of the present invention is to significantly reduce the waiting time due to the operation of reading scenario data in the image display device as described above. An object of the present invention is to provide an image display device capable of performing.

Another object of the present invention is to provide an image display device which can reduce the development load of the scenario creating tool.

[0013]

In order to achieve the above object, in the present invention, an image storage means having an attribute information storage means for storing image file attribute information, and an image is read from the image storage means. An image display device for continuously displaying images in accordance with a predetermined display procedure, wherein the attribute information storage unit stores attribute information relating to image reproduction control. A reproduction control means for reproducing an image based on the reproduction control attribute information stored in the information storage means is provided.

In order to achieve the above-mentioned other object, a list display control means for displaying a list of image information relating to the images stored in the image storage means on the image display device, and a display by the list display control means. A display order information organization means and a display attribute information organization means for organizing the display order information and the display attribute information are provided for the obtained image information.

[0015]

In the attribute information storage means, in addition to the file attributes of the images, the attribute information relating to the reproduction control of those images is recorded. According to the attribute information regarding the reproduction control, the display order of the images recorded in the image storage unit,
It is possible to know the information regarding the display effect to be added when displaying each image. As a result, by reading an image from the image storage means according to a general file access method, it is possible to read together information regarding an image that is continuous before and after the image and information regarding a display effect added to the image. As a result, it is possible to significantly reduce the waiting time caused by the conventional scenario data reading.

Further, as described above, the attribute information relating to the reproduction control of the image (corresponding to the conventional scenario) is recorded in the image storage means as the attribute of the image, so that the attribute information relating to the reproduction control is rewritten as text data. No need to convert to. Therefore, it is possible to reduce the development load of the reproduction control information creation tool which is the conventional scenario creation tool.

Further, according to the list display control means, the display order information organization means, and the display attribute information organization means, it is possible to intuitively operate while listing the information on the images stored in the image storage means. An image reproduction control procedure can be set.

Hereinafter, description will be made assuming that a plurality of presentation execution units are recorded on the optical disc. Here, the presentation execution unit refers to an aggregate of image data closed as one presentation.

At the initial stage after turning on the power of the apparatus,
The operation of forming the presentation execution unit selection screen is first performed. First, the disc information and the directory area 2 recorded in the disc volume section 21.
The directory information recorded in No. 2 is read from the disk drive device 6 into the operation control unit 2 via the interface unit 7 and the system bus 1. Among the read directory information, the attribute information relating to the progress of the presentation such as the directory position of the next display image is managed by the presentation information management unit 5, and the other attribute information is managed by the image information management unit 4.

Next, the directory of the first image of each presentation is searched according to the disc information. The data in the directory area 22 is read in advance by the image information management unit 4 as described above. The directory 24 (for example, 24a) of the target image is searched and the leading cluster of the corresponding image header 26 is known. Figure 3 (b)
As shown in FIG.
Since the first cluster and the data size of 7 and the first cluster and the data size of the main body image data area 28 are recorded, the leading cluster position of the reduced image data area 27 is searched from this information, and the data is sequentially read out, and the display memory circuit Send to 9.

By repeating this operation, only the reduced image corresponding to the first image of each presentation is read and transferred to the display memory circuit 9.

The reduced image data successively transferred to the display memory circuit 9 is organized as a multi-screen by the display control circuit 8 and displayed on the display 10. In parallel with this operation, the display control circuit 8 controls so that the identification name of each presentation is superimposed and displayed on each reduced image displayed on the display 10.
In this way, the presentation execution unit selection screen is formed.

FIG. 4 shows an example of a selection screen for this presentation execution unit, and 41 is the display 1
Display screen 0, 42a, 42b, 42c ..., 42j are reduced images of the first screen of each presentation execution unit, 43
Is an identification name of the presentation execution unit, and is referred to as a reduced image 42 and an identification name 43 when referring to unspecified reduced images and identification names. Reference numeral 44 is a selection frame which assists in selecting and deciding the presentation to be executed. In this example, the reduced image has a size of 1/16 of the original image, and the number of presentation execution units recorded on the optical disc is 10 sets.

FIG. 5 is a diagram showing a specific example of the remote control transmitter 13 shown in FIG. 1. Reference numeral 51 denotes an instruction to move the selection frame 44 displayed on the display 10 when selecting a presentation execution unit or image search. Cursor keys to send to the device, 5
Reference numeral 2 is an execution key for starting the execution of the presentation, 53 is a search key for issuing a command to search for an image recorded in the disk drive device 6 when the presentation is executed or in the initial state of the apparatus, and 54 is a presentation execution A forward key sometimes instructs to change to the next display screen, and a backward key 55 also instructs to return to the previous display screen.

It should be noted that the search by the search key 53 is an image search in presentation units during the execution of a presentation, and all image data recorded in the disk drive device 6 in the initial state of the device.

The user refers to the reduced image 42 and the identification name 43 of the presentation execution unit, and uses the cursor key 51 of the remote control transmitter 13 to set the presentation selection frame to the reduced image 42 indicating the desired presentation execution unit, for example, the reduced image. It is moved to the position of 42f. By pressing the execution key 52 in this state, the reduced image 4
A control command to execute the presentation corresponding to 2f is sent to the device.

The presentation execution command is received by the remote controller receiver 12 and transferred to the operation controller 2 via the system bus 1. CPU in operation control unit 2
3 interprets the execution instruction and reads the target image from the disk drive device 6. This reading procedure is almost the same as the case of reading the reduced image described above. That is, since the position of the directory corresponding to the selected reduced image 42f is already known, this directory is searched and the image header 26 written at the beginning of the data area 25 of the optical disc is read. As described above, the head cluster position and the data size of each of the reduced image data and the main image data are recorded in the image header 26.
As a result, the head cluster of the main body image data area 28 is known, and the data is sequentially read. At this time, the information about the display effect written in the image header 26 is also read at the same time and transferred to the presentation information management unit 5.

The read operation may differ depending on the image attribute. Directory 2
If compression is designated as the attribute of this image in the image file attribute area 31 of No. 4, the data read from the main body image data area 28 is restored to the original image by the image expansion circuit 11 and then the display memory circuit 9 is restored. If the non-compression is designated, it is directly transferred to the display memory circuit 9.

In parallel with the above transfer operation, the presentation attributes read in the presentation information management section 5 are interpreted. The presentation attribute includes an effect added at the time of display and a directory position corresponding to the image to be displayed next (second image in this example). First, the display effect to be added when displaying the first image is interpreted, and a control signal corresponding to this display effect is sent to the display control circuit 8. Following this operation, the directory for the second image is searched to find the recording position of the second image body.

The image data stored in the display memory circuit 9 is converted into a video signal by the control signal of the display control circuit 8 and displayed on the display 10. At this time, the display effect (fade) specified in the presentation attribute is displayed. , Wipes, etc.) are also added by the display control circuit 8. After this, the device is in a state of waiting for the input of a display screen switching command from the user.

The progress of the presentation (switching of the display screen) is repeated by reading and displaying the above-mentioned image data by a forward / backward command which is usually issued by the user with the forward / backward keys 54/55 of the remote control transmitter 13. It is done by going. Backward movement of the display screen,
That is, the operation of returning to the previous display screen is also possible because the directory position of the previous display image is recorded in the directory 24. Similarly, skip forward / backward display (display the next or previous image without displaying the next or previous display image)
This can be dealt with by searching 4 sequentially. The skip display from the user may be designated by skipping forward, for example, by pressing the forward key 54 of the remote control transmitter 13 twice or more continuously. Or, the remote control transmitter 13 is provided with a numeric keypad,
Of course, the number of images in the presentation execution unit may be directly specified.

Depending on the form of the presentation, there may be an execution method in which the display screen is automatically switched in addition to the method in which the person advances using the remote controller or the like.
In this case, the image header 26 corresponding to each image
In addition, if each image is written for a time such as displaying for several seconds, it can be easily realized.

As described above, in the presentation apparatus to which the present invention is applied, when managing an image on an optical disk, information regarding the progress of the presentation is written in the directory area, and the image header at the beginning of the image data area is written. In, the display effect when displaying the image is written. Thus, by searching the directory, the display order of the images in the presentation execution unit can be known, and by reading the image, the display effect to be added when displaying the image can be known. Therefore, the program (scenario) describing the display procedure, which is conventionally required in this type of device, can be regarded as being divided and recorded as the attribute of each image.

The image retrieval operation is possible during the execution of the above-described presentation and in the initial state of the apparatus. The images to be searched are all the images recorded on the optical disc in the search in the initial state, and the images in the presentation execution unit being executed during the presentation.

The image search is started by pressing the search key 53 of the remote control transmitter 13 in each state of the above apparatus. The operation of selecting the image to be searched is the same as the operation of selecting the presentation execution unit described above, and the screen selection is performed by the multi-screen display. However, in the image search, when one image is selected and confirmed, the disk drive device 6 immediately starts the search operation, and the selected image is displayed instead of the multi-screen for search.

Next, with respect to the presentation apparatus of the present invention, a procedure for recording a presentation image and a presentation execution procedure on an optical disc (hereinafter, these operations are collectively referred to as editing) will be described with reference to FIGS. .

FIG. 6 is a block diagram showing an example of the configuration of the presentation device to which the present invention is applied during editing. The same components as those in FIG. 1 are designated by the same reference numerals. In FIG. 6, the image decompression circuit 11 and the remote controller receiver 1 of FIG.
2 and the remote control transmitter 13 are deleted. Reference numeral 60 denotes an image compression circuit that compresses an image according to a user's specification when recording the image on an optical disk, and 61, a reduced image generation circuit that generates a reduced image for use when searching for an image or selecting a presentation execution unit. 62 is a mouse 6 described later.
Mouse interface for connecting 3 to the device, 63
Is a mouse for assisting various commands when the user executes editing, 64 is an image input means for inputting an image to the apparatus, and 65 is means for inputting a character code such as a file name as image attribute information. The keyboard to use.

FIG. 7 is a diagram showing an example of an initial screen displayed on the display 10 after the power of the presentation apparatus of FIG. 6 is turned on, and is a screen for selecting and operating a command to be executed. In FIG. 7, 71 is a command selection / operation area, 72 is an image display area, and 73 is an aid when the user operates a command in the command selection / operation area 71.
A cursor whose operation is controlled by the mouse 63.

The editing command is a command for controlling an operation of recording an image used for a presentation (hereinafter referred to as an image file operation command) and a command for controlling an operation of registering a presentation execution procedure (hereinafter, execution procedure setting). Command)). The registration of the presentation execution procedure is performed when all the images forming the presentation execution unit have been recorded. Hereinafter, the image recording operation and the presentation execution procedure registration operation will be described in this order.

The image file operation command includes the following five commands. "Input" command to input an image from outside the device, "Save" command to record the image input to the device on the optical disk, to delete unnecessary data from the image data recorded on the optical disk “Delete” command, “Display” command for searching and displaying image data recorded on the optical disk, and “Format” command for formatting the optical disk in preparation for recording an image. In the following description of the image recording procedure, it is assumed that the optical disc has been physically formatted using this "format" command.

In the formatting process, the physical sector on the disk is divided into the disk volume section 21, the directory area 22 and the data area 25, and the head cluster number of the directory area 22 is stored in the disk volume section 21 as the directory area. The head cluster number of the data area 25 is written in the header 23 of 22.

In order to input an image, the user operates the cursor 73 displayed on the display 10 with the mouse 63 and selects the "input" command from the image file operation commands. When the CPU 3 accepts this command, the device enters an image input waiting state and displays a message prompting the user to input an image on the display 10.

The image created by the image creating means (not shown) is input to the apparatus through the image inputting means 64. The input image is transferred to the display memory circuit 9 via the system bus 1, and the display control circuit 8 causes the display 1 to display.
0 is displayed in the image display area 72. Next, the user selects "save" in the image file operation command with the mouse 63. When this command is selected, a message prompting you to enter a file name to identify the image,
The characters are displayed on the display screen of the display 10 so as to overlap each other, and the character code input waiting state is set.

In this state, the user uses the keyboard 65 to input a desired file name. The input file name is stored in the image information management unit 4 as image attribute information. Subsequently, a message prompting the user to select whether to compress the image or save it as uncompressed is displayed, and the input waiting state is resumed. The selection of a compression attribute (compression / non-compression) is performed by operating the cursor 73 displayed on the display 10 with the mouse 63. FIG. 8 shows an example of the display of the command selection / operation area 71 at this time. Mouse 6
The cursor 73 is moved to, for example, the character display of "compression" by 3, and the compression recording is designated by clicking. Similarly, if you select uncompressed recording, "uncompressed"
It is sufficient to move the cursor 73 to the character display of and click. Clicking refers to the action of pressing the switch button attached to the mouse once and then immediately releasing it. The input compression attribute is stored in the image information management unit 4 as in the case of the file name.

When the designation of the file name and the compression attribute is completed, the CPU 3 searches the data area 25 of the optical disk loaded in the disk drive device 6 to find a free area. When a free area is found, image data is sequentially read from the display memory circuit 9 and transferred to the disk drive device 6. When compression is designated as the attribute, the image compression circuit 60 performs compression processing and then transfers the compressed data to the disk drive device 6. In this example, the disk is assumed to be an unused disk that has just undergone physical formatting, so image data is written sequentially from the first cluster of the main image data area 28 of the data area 25. When the writing of the body image data is completed, the leading cluster number and the data size of the body image data area just written are recorded in the image header 26.

Next, a process of creating and recording a reduced image which is necessary for retrieval or the like is performed. First, the display memory circuit 9
The image data is read from and is transferred to the reduced image generation circuit 61. The generated reduced image data is sent to the disk drive device 6 and written in the reduced image data area 27 in the data area 25 in which the main body image data was written previously.
After writing the reduced image data, the image header 26
The leading cluster number and data size of the reduced image data area 27 are recorded in. Therefore, each head cluster number in which the reduced image and the body image are recorded and each data size are recorded in the image header 26. When the data writing to the data area 25 is completed, the process shifts to the process of writing the file attribute information regarding this image to the directory 24.

The file attribute information written in the directory 24 at this stage includes the following information. First, there are a file name and a compression attribute for identifying the image input by the user, a head cluster number of the corresponding data area 25, a date and time when the file is created / updated, and the like. These image file attribute information are stored in the image information management unit 4.
Is created, transferred to the directory 24, and written.

Finally, information is written in the disk volume section 21. At this stage, the only information written in the disc volume section 21 is the number of registered images.

The operation of recording one image data is performed by the procedure as described above. By repeating the above procedure, an image can be recorded as long as the capacity of the optical disc allows. Also, by executing the "delete" command, it is possible to remove unnecessary data from the data recorded on the disc.

Next, the registration operation of the presentation execution procedure will be described assuming that the data corresponding to a plurality of images is recorded on the optical disc by repeating the above image recording procedure. The registration of the presentation execution procedure is executed by selecting the execution procedure setting command with the mouse 63 in the command selection / operation area 71. The execution procedure setting command is further divided into two functions. From the images registered on the optical disc, select the images to use for the presentation and determine the display order, and specify the display effect to be added to each image when displaying the images. It is a "display effect" command.

Since the command selecting operation is the same as the case of the image recording operation described above, in the following description, the description will be limited to "execute the" image selecting "command".

FIG. 9 is a diagram showing a display example of the display 10 at the start of execution of the “image selection” command, and FIG. 10 is a display example during execution of the image selection command. In addition,
The same reference numerals are given to the same elements in FIGS. 7, 9 and 10. In FIG. 9, 91a, 91b, 91c, 91
, 91l are reduced images read from the optical disc loaded in the disc drive device 6, respectively.
In 0, 101a, 101b, and 101c are numbers for showing the user the selected image and the selected order of the images.

According to the present invention, the order selected by the image selection command is the display order within the presentation execution unit as it is. When the image selection command is selected, the directory area 22 of the optical disc is selected.
Data area 2 corresponding to each directory 24
The reduced images are sequentially read from the reduced image data area 27 of 5,
At the same time as writing to the display memory circuit 9 for multi-screen display, a cursor 7 for assisting the user in selecting an image
3 is displayed. With the above operation, the display screen as shown in FIG. 9 is completed.

The user selects 12 reduced images 99a, 99b, 99c ..., 99l displayed on the screen as a multi-screen.
From among these, select the image that should be the first screen of the presentation execution unit. The image selection operation is the same as the command execution operation.
Is moved to a reduced image (for example, 91f) showing a desired image, and the switch button of the mouse 63 is clicked. At this time, the CPU 3 detects which image is selected by monitoring the existing position of the cursor 73 when the mouse 63 is clicked. As shown in FIG. 10, on the selected image 91f,
The number 100b indicating the selected order is the display control circuit 8
Displayed by. On the other hand, at this time, the presentation information management unit 5 creates a rank table showing the correspondence relationship between the selected image and the display rank in the presentation execution unit based on the image selection information.

If there is no desired image among the 12 images displayed first, by selecting the command for the next screen display in the command selection / operation area 71,
The next 12 candidate images are displayed. If there is a target image in the 12 reduced images displayed as a result, the above selection determination operation is performed. By repeating the above operation,
A display image in the presentation execution unit and its display order are determined. Then, each time one image is selected, the ranking table in the presentation information management unit 5 is updated. When the user finishes the necessary image selection, he / she selects the end command in the command selection / operation area 71.

When the image selection end instruction is given, the multi-screen is reconstructed by arranging only the reduced images of the images selected based on the order table in the selected order,
At the same time as prompting the user to confirm, a message prompting the user to enter the presentation name for identifying the presentation execution unit is displayed, and the input of the character code from the keyboard 65 is awaited. When the character code indicating the presentation identification name is sent from the keyboard 65, it is written in the presentation information management unit 5. The user can see the multi-screen composed of only the selected images, issue a confirmation command if there is no defect, and return to the image selection mode again if he / she wants to make a change. When the user's approval is obtained, the directory area 24 of each selected image is based on the order table recorded in the presentation information management unit 5.
The data indicating the display order and the presentation identification name are written in. As a result, when the presentation is executed, by referring to the display order data written in the directory 24, it is possible to move the display screen forward / backward / skip. When the operation of recording the presentation attribute information in the directory area 24 is completed,
The presentation name and the number of presentation registrations registered in the disk volume section 21 (1 in this example)
Is recorded.

As described above, since the presentation identification name is always added to one presentation execution unit, it is possible to mix a plurality of presentation execution units on one optical disk.

When the "image selection" command is completed,
The next step is to set the display effect when the presentation is executed using the "Display effect" command. "Display effect"
When the command is specified, the CPU 3 reads the number of presentation registrations and each presentation name recorded in the disc volume section 21 of the optical disc. Next, the number of registered presentations is checked, and when there are a plurality of presentation registrations, the reduced image corresponding to the first image of each presentation execution unit is read out in the same procedure as in the case of the presentation execution described above. The read out reduced image is transferred to the display memory circuit 9 to form a multi-screen, and a mode for allowing the user to select a presentation execution unit to be a display effect setting target is entered. The selection operation in this case is the same as the previous image selection operation, and thus detailed description thereof will be omitted.

When the number of registered presentations is 1 and when one execution unit is selected from the plurality of presentation execution units by the selection determining operation, the reduced image of the image included in the presentation execution unit is selected. Is read from the optical disc and transferred to the display memory circuit 9. FIG. 11 shows an example of the screen displayed on the display 10 at this time. The same parts as those in FIGS. 7 and 9 are designated by the same reference numerals. 110a, 110b, 1
Reference numerals 10c, 110l denote reduced images corresponding to the images included in one presentation execution unit read from the optical disc, and 111 assists the user in recognizing the image currently set as the display effect setting. It is a frame.

By executing the "display effect" command, the reduced images of the images included in a specific presentation execution unit are displayed on the multi-screen while maintaining their display order.
The display effect is set according to the display order. In the example of FIG. 11, the setting of the display effect is started from the image 110a at the upper left corner of the display screen, and the setting is advanced in the order of 110b, 110c and 110d. When the display effect setting for one image is completed, the auxiliary frame 111 is displayed on the image to be set next, so the user does not need to be aware of the order.

FIG. 12 is a diagram showing an example of a part of the display of the command selection / operation area 71 in the display screen at the time of executing the "display effect" command. Is attached. 120a, 120b,
Reference numerals 120c and 120d are icons that schematically show the display effect. Mouse 63 on the icons 120a to 120d
The display effect is set by moving the cursor 73 using and and clicking.

The information regarding the display effect selected by the user is stored in the presentation information management section 5, and an effect table showing the correspondence between each image and the display effect is created therein. Each time the display effect is set for each image, the effect table is updated, and when the display effect setting is completed for all the images forming the presentation execution unit, each image on the optical disk is finished. Is recorded in the image header 26 corresponding to.

If all the images forming one presentation execution unit cannot be displayed on the multi-screen composed of 12 reduced images shown in FIG. 11, the 12 previously displayed images are displayed. When the setting of the display effect for the image is completed, the operation of updating to the next multi-screen is performed, and the above-described display effect setting operation is continued.

As described above, in this embodiment, information such as the display order necessary for the progress of the presentation and the display effect to be added is attached to the image file as the attribute of each image and recorded on the optical disc. Therefore, when the presentation is executed, the information about the progress of the presentation can be read by reading the image, and the waiting time can be significantly reduced as compared with the conventional scenario in which the separate file is used. Further, for the same reason, since it is not necessary to create a scenario file which is text data, it is possible to reduce the development load of a tool for creating attribute information relating to reproduction control, which is equivalent to a conventional scenario.

In the present embodiment, the attribute information recorded in the directory or the header section is only an example, and if it is similar or has similar effects, other information may be recorded. You can

Further, although the presentation execution unit selection and the image selection operation are performed on the multi-screen display,
Other methods are also acceptable. As an example of multi-screen display,
Although FIG. 9 and the like are shown, the number of reduced images to be displayed is not limited to this, as long as the user can recognize the original image and also provides the same function. , More or less than this.

Further, in the present embodiment, the structure of the presentation device is described separately for the execution of the presentation and the editing. However, as the structure of the device, the reproducing and editing functions are separated as in the present embodiment. It does not matter whether it is realized by a device or a single device, regardless of the essence of the present invention.

[0073]

As described above, according to the present invention, in an image display device which has been conventionally used for a presentation or the like, data describing a display procedure is recorded as an attribute of an individual image, not as a single file. I chose
As a result, the number of accesses to the recording medium can be reduced, and smooth image display can be performed even when a medium having a low access speed such as a CD-ROM is used. Further, for the same reason, it is possible to avoid that a plurality of types of data are mixed on the same medium, and the file management efficiency is improved.

Further, when the presentation is executed, the information about the progress of the presentation can be read by reading the image, and the waiting time can be greatly reduced as compared to the conventional scenario in which a separate file is used. Further, for the same reason, since it is not necessary to create a scenario file which is text data, it is possible to reduce the development load of a tool for creating attribute information relating to reproduction control, which is equivalent to a conventional scenario.
