[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration of an embodiment of the present invention, in which 1 is a host computer (hereinafter simply referred to as a host), 2 is an HDTV character generator (hereinafter simply referred to as a character generator), 3 is an HDTV video disc player (hereinafter referred to as LDP), 4 is an HDTV wiper (hereinafter referred to as a wiper), 5 is an HDTV still image reproducing device (hereinafter referred to as a still image reproducing device), and 6 is a CD-ROM.
Processor (hereinafter referred to as processor), 7 is an image CD
-ROM player (hereinafter referred to as image CDD), 8 is an HDTV decoder (hereinafter referred to as decoder), 9 is an audio CD-ROM player (hereinafter referred to as audio CDD),
10 is a mix amplifier, and 11 is a mouse.

First, the configuration and operation of each component shown in FIG. 1 will be described. The host 1 controls the screen transition based on the screen currently displayed on the display device (not shown) and the menu specified by the mouse 11.
When the instructed menu is accompanied by the display of characters, the character generator 2 is operated, and when it is accompanied by the display of a moving image, the LDP 3 and the wiper 4 are operated,
If the still image is to be displayed, the still image reproducing device 5 is operated. The process of transition of this screen will be described in detail later. The character generator 2 generates a high-quality character font from the R, G, B character data supplied from the host 1, converts it into HDTV specification Y, _Pb , _Pr signals and outputs it to the mix amplifier 10. To do. The character color is white. The LDP 3 reproduces a moving image between the addresses designated by the host 1. Here, it is assumed that the video disc adopts the constant angular velocity method (CAV) in consideration of ease of special reproduction such as slow motion reproduction and still reproduction, and high speed of image retrieval.

Since HDTV has a huge amount of information, it is known that a CAV video disc can store only a moving image of about 8 minutes on one side. In the electronic publishing system according to the present invention, still images are mainly used as will be described later, and moving images are only used as partial images. However, effective use of moving images enhances effectiveness as electronic publishing. Therefore, it is desired that more moving images can be stored. Therefore, two or more different moving image materials are simultaneously recorded on the video disc used in this electronic publishing system, and only the desired image among them is extracted by the wiper 4 to mix amplifier 1
0, so that it is combined with the still image from the decoder 8. For example, if two moving image materials of different A and B are recorded at the same time as shown in FIG. 2A, when an image reproduced from the video disc by LDP3 is directly supplied to the display device, as shown in FIG. 2A. Two moving images of A and B are displayed on the screen. By instructing the moving image from the host 1 to the wiper 4,
As shown in FIG. 2B or 2C, only a desired moving image can be extracted and supplied to the mix amplifier 10. The shaded portion in FIG. 2 is a black signal.

The LDP 3 also outputs two-channel audio signals CH ₁ and CH ₂ . In this case, the narration or background music (BGM) relating to the moving image material of FIG. 2A is recorded in one channel, and the narration or BGM relating to the moving image material of B is recorded in the other channel. , The LDP 3 outputs only the audio signal corresponding to the selected moving image. By adopting the above recording method, a moving image of about 16 minutes can be recorded on the video disc. When three or more moving images are recorded, the voices corresponding to those moving images may be data-compressed and recorded in time division. The wiper 4 extracts only a predetermined moving image from the moving images reproduced by the LDP 3 according to the instruction from the host 1 as described above, but the moving image is displayed by simply extracting one moving image. The position to be recorded is uniquely set to the position recorded on the video disc. In order to avoid this, the position to be recorded may be set in consideration of the position to be displayed for each moving image in advance.
It is also possible to move the display position of the moving image by a control signal from.

Next, the still picture reproducing device 5 will be described.
The processor 6 receives the image CDD according to the instruction from the host 1.
7 and the audio CDD 9 are activated to reproduce the designated address of the image CD-ROM and / or the audio CD-ROM. The audio signal reproduced by the audio CDD 9 is L
It is supplied to an audio circuit (not shown) together with the audio signal output from DP3, subjected to audio signal processing such as amplification, and output to a speaker. Y, P output from image CDD7
_{The b} and P _r still image signals are written in the plane memory of the decoder 8, read out in synchronization with the scanning of the display device, and supplied to the display device. The plane memory has a memory space of 2048 × 2048 pixels as a whole as shown in FIG. 3, for example, and an area of 1280 × 1024 pixels indicated by the shaded area in the plane memory is set as a base image area. That is, the image CD
The still image data read from D7 is written in the base image area. The other empty area of the plane memory is used as a superimposed image development area, and a pattern such as a menu or icon that needs to be displayed instantaneously is written.

The write address of the still image pattern read from the image CDD7 to the plane memory may be given from the host 1 to the decoder 8. However, in this embodiment, the still image data itself read from the image CDD7 is provided. Be present. That is, the image CDD
The write address and the still image pattern are read from 7, and the disk 8 writes the still image pattern in accordance with the write address. Therefore, when the still image pattern to be read is the base image, the write address in the shaded area in FIG. 3 is accompanied, and when the still image pattern is the menu or the icon, a predetermined write operation other than the base image area is performed. Accompanied by an address.

As will be described later, the menus and icons are displayed overlaid on the base image. Therefore, the menu pattern and icon pattern are read from the overlay image development area of the plane memory and overlaid at a predetermined position on the base image area. Written The address on the base image area where the menu pattern and icon pattern are overwritten at this time is designated by the host 1. Although only one plane is shown in FIG. 3, it has a capacity of a predetermined number of bits for each of the Y, P _b , and P _r signal components, and is capable of displaying a full-color image. Of course there is. As mentioned above, the number of HDTV pixels is 1920 x 10
The number of pixels in the base screen area set in the plane memory is smaller than that of 35 pixels. Therefore,
The still image pattern read from the plane memory is vertically and horizontally expanded so as to satisfy the aspect ratio of HDTV when converted into an analog signal.

The still images recorded on the image CD-ROM include full mode images and half mode images. The full mode image is an image having the same number of pixels as the number of pixels of the base image area of the plane memory, and the half mode image is an image having half the number of pixels of the base image area. Therefore, in the case of the full mode image, the still image pattern data read from the image CDD7 is sequentially written in the base image area according to the write address, but in the case of the half mode image, the read pattern data of one pixel is Copied to the following address The reason for adopting the two recording modes, the full mode and the half mode, is as follows. When one still image is recorded in the full mode, that is, when each signal component of Y, P _b , and P _r is recorded with the number of pixels of 1280 × 1024, its capacity is about 3 Mbytes. Although it is possible to display a high-quality still image by such full mode recording, there is a disadvantage in that it takes about 15 seconds to reproduce and the reproduction time is long. Therefore, the half mode is adopted to reduce the reproduction time, and the reproduction time can be halved as compared with the full mode. However, although the half mode is effective when the base image is a photograph or the like, it is not advisable to adopt the half mode for the base image having many characters. This is because pixel interpolation may make small characters unreadable.

The mix amplifier 10 includes a character generator 2,
The outputs of the wiper 4 and the decoder 8 are combined and output to the display device. Although various types of image signal synthesizing methods in the mix amplifier 10 can be adopted here, in the present embodiment, the outputs of the character generator 2, the wiper 4 and the decoder 8 are simply added. As a result, the mix amplifier 10 can be constructed at low cost. However, when the images are combined by signal addition, the brightness of the base image is high, and when the brightness of the image superimposed on a part of the base image, for example, the moving image from the wiper 4 is low, the base image in the back is displayed. However, there is a problem that the picture on the base image interferes and the picture on the base image becomes transparent. Therefore, in the present embodiment, the decoder 8 is provided with a plane memory separately from the above-mentioned plane memory, and in the case of superimposing a moving image, as shown in FIG. 4, the moving image in the base image area of the plane memory is The black window 15 is written at the position where the is overlapped. Then, the pattern of the black window 15 is supplied to the mix amplifier 10 and is combined with the moving image and the still image.

By always performing the above processing when displaying a moving image, it is possible to prevent interference of the base image with the moving image regardless of the luminance of the base image and the luminance of the moving image. Thus, a good moving image can be displayed. As for the pattern of the black window 15, some types of patterns are image CD-ROM depending on the size and display position of the moving image.
The host 1 issues a reading instruction in accordance with the moving image to be displayed. Black window 15 read out
The host 1 also designates the addressing of which position in the base image area the pattern is written. In addition,
As described above, the character output from the character generator 2 is white, which is higher than the brightness of the base image, so that the character is displayed well. The mouse 11 is used as a pointing device, by which a menu on the display screen is selected.

The configuration and operation of each section in FIG. 1 have been described above. Next, the screen transition and the operation of each section at that time will be described. There are two types of programs, "Kanto Golf Course Guide" and "Endangered Animals".
It is assumed that the screen transition is as shown in FIG. That is, in FIG. 5, first, a comprehensive title screen (frame (hereinafter referred to as FRM) 1) is displayed, from which a golf course guide title (FRM 2) and an animal title (F
RM10) and go to the map guide screen (FRM) to search for the desired golf course for the golf course guide.
3) and the name search screen (FRM4), and when the golf course is selected, the introduction screen (FRM6) of the golf course is displayed, and then the home screen (FRM7) is displayed from the golf course. Screen of course guide (F
RM8), traffic guide screen (FRM9) can be selected, and for animals, the title screen (FRM10) is followed by a screen for selecting a desired animal (F
RM11) is displayed, and when an animal is selected there, an animal introduction screen (FRM12) is displayed.

The host 1 controls the screen transition shown in FIG. 5, and therefore the host 1 has some files. An example thereof is shown in FIG. FIG. 6A is a diagram showing an example of the structure of an input coordinate file indicating which area of the currently displayed screen is to wait for coordinate input, and according to the figure, when FRM1 is displayed, The input of the coordinates in the area 1 and the coordinates in the area 2 is awaited. If the FRM1 is as shown in FIG. 7A, the regions 1 and 2 are, for example, 2 in FIG.
Areas 0 and 21 are set. The same applies to FRM2 and later. FIG. 6B shows the currently displayed FRM.
It is a figure which shows the structural example of the file (henceforth a file is called a tree file) in which the number of the FRM which changes from and the screen information of the FRM are written. According to the figure, when FRM1 is displayed. When the coordinates in the area 1 are input to, that is, when the mouse 11 clicks within the area 20 in FIG. 7A, the FRM2 golf course title screen is displayed next, and the coordinates in the area 2 are changed. It is stipulated that, when input, the transition to FRM10 is made. Further, auxiliary pattern display information, LDP3 control information, and character string information are written as necessary as screen information for forming each subsequent FRM.

Here, the auxiliary pattern display information is information for displaying a menu and an icon, and the menu, the type of the icon, its display position, etc. are written therein. In the control information of the LDP3, information such as the address range of the video disc to be reproduced, the image to be extracted, the audio channel to be output, etc. is written. Further, the character string information is written with information on the pattern to be output from the character generator 2. These pieces of screen information are written as needed. For example, if a moving image is not displayed when FRM2 is displayed, control information of LDP3 is not written. The above is F
The same applies to RM2 and later.

FIG. 6C shows image CD- for each FRM.
Address of still image to be played from ROM, audio CD-
Voice address to be reproduced from the ROM, a diagram showing a structural example of a CD-ROM file views voice is written, CV ₁ from the image the CD-ROM to display the FRM1 According to FIG. Play the range of ~CV _2, it has been made so as to reproduce an infinite number of times the range of the CS ₁ ~CS ₂ from the audio CD-ROM. The infinite number of times of reproduction means that a predetermined range of addresses is repeatedly reproduced until the next coordinate input. Image CD-ROM
It goes without saying that the reproduction address of 1 includes reproduction of a black window pattern used when a moving image is combined. Further, in FIG. 6C, CV and CS are written as addresses, but this is for easier understanding, and in reality, C
The D-ROM address is defined by minutes, seconds and blocks. The same applies to FRM2 and later.

FIG. 6D is a diagram showing an example of the structure of a character text file, in which character string data to be generated from the character generator 2 is written. For example, as shown in FIG. 5, FRM5 is a screen in which golf course names are enumerated, and the golf course names are output from the character generator 2. Therefore, an instruction for giving the golf course name to the character generator 2 as character string information is written in the screen information for transition to FRM5, and in response to this, the host 1 refers to the character text file to play the golf. The character string data of the place name is supplied to the character generator 2. This gives F
The RM5 screen is displayed.

The host 1 controls the screen transition by referring to these files comprehensively, and the reason for configuring in this way is that it is advantageous for the maintenance of programs and files. That is, it is possible to incorporate all the conditions for screen transition into a program, but in that case, if the scenario is changed, the program must be significantly modified, which is very troublesome. On the other hand, if the screen transition condition is set to a file as described above, when the scenario is changed, only the corresponding part of the file needs to be corrected, which can be easily performed. The file is not limited to the one described above, and for example, the control information of the LDP3 can be an independent file like the CD-ROM file shown in FIG. 6C, and conversely, for example, the CD shown in FIG. 6C. −
It is possible to include a ROM file in the tree file, but there is a drawback that the file management becomes complicated when the number of files is large, and the processing becomes complicated. If the data amount of one file is large, maintenance will be hindered. Will come. Therefore, although four types of files are shown in FIG. 6, this is just an example even if it gets tired, and the number of files and the structure thereof are arbitrarily set in consideration of ease of maintenance, ease of file management, and the like. It will be apparent to those skilled in the art that this can be done.

A specific example of screen transition will be described below. Video disk to LDP3, image CD-ROM to image CDD7, and audio CD-ROM to audio CDD
Set to 9 and start the electronic publishing system,
The host 1 first refers to the comprehensive title screen (FRM
1) and instructing the processor 6 to read out a predetermined menu and icon pattern. This gives the image CDD
The still image of the general title reproduced in 7 is written in the base image area of the plane memory, read in synchronization with the scanning of the display device, and displayed on the screen. Further, the menu pattern and the icon pattern are written at a predetermined address in the overlapping image development area. Of course, this processing is performed by the host 1 by referring to the above file.

An example of the comprehensive title screen is shown in FIG. 7A. In FIG. 7A, two titles, “Kanto Golf Course Guide” and “Endangered Animals” are displayed on the screen.
At this time, the audio CD-ROM may be reproduced so that narration or BGM for explaining the title can be played. The pattern of the cursor 19 is displayed by overwriting the pattern previously written in the overlay image development area on the base image area. The display position is determined by the host 1 by constantly monitoring the movement of the mouse 11.

Next, when there is a coordinate input, the host 1 refers to the input coordinate file and determines whether the input coordinate is within the range of the area 1 or the area 2. When the host 1 determines that the input coordinates are within the area 1,
The color of the character string “Kanto Golf Course Guide” is reversed and a response is returned to the user, and the plain memory 6 is instructed to display the next golf course title screen. This color reversal process is performed by instructing the plane memory 6 to read out the color-reversed pattern of the character string. That is, the color reversal pattern for these two character strings and the write address on the base image area are recorded in advance on the image CD-ROM. Now, in the area 2 in the screen of FIG. 7A.
If 0 is instructed, the host 1 gives an instruction to read the color inversion pattern of the “Kanto Golf Course Guide”. The color inversion pattern thus read is written in a position corresponding to the area 20 in FIG. 7A in the base image area. Since the color reversal pattern has a small capacity, it can be displayed in a short time. It should be noted that this color inversion processing is naturally performed based on the screen information written in the tree file.

When "Kanto Golf Course Guide" is selected on the screen of FIG. 7A, the title is color-inverted by performing the above processing, and the host 1 further causes the processor 6
Then, the next screen, that is, the title screen of the Kanto golf course guide and the corresponding narration are read. As a result, the title screen is reproduced from the image CDD7, and the reproduced still image is written in the base image area of the plane memory of the decoder 8 and supplied to the display device. Further, the sound corresponding to the title screen is reproduced from the sound CDD 9, but the reproduction of this sound is repeated until some operation is performed by the mouse 11.

An example of the title screen (FRM2) is shown in FIG.
Shown in B. Since fine characters are not used in this still image, the still image can be recorded in the half mode, whereby the reproduction time can be shortened. Then, when the mouse 11 is right-clicked on this screen, a search menu 22 is displayed, for example, as shown in FIG. 7C, and a predetermined sound is repeatedly reproduced. The display of the menu 22 is performed by overwriting the menu pattern previously written in the overlay image development area at a predetermined position in the base image area. Needless to say, at this time, the position of the base image area in which the menu pattern is overwritten is given from the host 1.

When the map search is selected on the screen of FIG. 7C, the “map search” column is color-reversed and the menu 23 as shown in FIG. 7D is displayed. At this time, the voice corresponding to the map search is repeatedly reproduced. In the display of the menu 23, the pattern previously written in the overlay image development area is overwritten and displayed. If, for example, Gunma is selected on the screen of FIG. 7D, the menu 23 is erased after the “Gunma” column has been flushed for a predetermined time, and the screen changes to the map of Gunma prefecture as shown in FIG. 7E. Here, the flushing can be performed, for example, by alternately displaying a normal pattern of “Gunma” and a color reversal pattern in a predetermined cycle. Then, when the desired area is selected with the mouse 11 on the screen of FIG. 7E, the color of the cursor 19 changes, and an enlarged map of the selected area is displayed as shown in FIG. 7F. The name of the golf course existing in the area is displayed on this screen. When the desired golf course is selected, the golf course name is color-reversed and the screen changes to the next screen. Here, the color change of the cursor 19 is performed by writing a cursor pattern having a different color in advance in the overlapping image development area and by overwriting the cursor pattern to be displayed in the base image area as necessary. You can Further, it is apparent that the color reversal of the golf course name can be performed in the same manner as the color reversal of the menu described above. Further, when the name search is selected on the screen of FIG. 7C, the menu 24 is displayed as shown in FIG. 7G. Similar to the menu 23, the display of the menu 24 is performed by writing the menu pattern in advance in the overlay image development area and then overwriting it at a predetermined position in the base image area.

When, for example, "ta" is selected on the screen of FIG. 7G, the color of the "ta" column is inverted, and the screen transitions to the next screen. Note that this color inversion is performed in the same manner as described above. The screen displayed next to FIG. 7G is, for example, as shown in FIG. 7H.
In a predetermined area of the display screen, a golf course name starting with a row, a scroll icon 25, and a scroll bar 26 are displayed. The character string of the golf course name, the pattern of the scroll icon 25, and the pattern of the scroll bar 26 are generated by the character generator 2. That is, host 1
7G detects that "TA" has been selected on the screen of FIG. 7G, it searches the golf course name file for a golf course name that starts with a TA line, and displays a scroll icon display command,
The character generator 2 is instructed together with the scroll bar display command. At this time, the host 1 also instructs the processor 6 to read the background pattern. As a result, in the mix amplifier 10, the image signal from the character generator 2 is superimposed on the image signal from the decoder 8. The golf course name is displayed on the screen shown in FIG.
-Although it may be recorded in a ROM and reproduced from there, it is not preferable that the reproduction time be long, and it is preferable that the character generator 2 generate high quality characters. The above operation is performed.

When the scroll icon 25 is clicked with the mouse 11 on the screen of FIG. 7H, the color of the selected scroll icon changes, and the scroll bar 26 moves up and down by a predetermined amount. The golf course name displayed by this is moved up and down by a predetermined number of lines. The color of the scroll icon 25 is instructed from the host 1 to the character generator 2. Then, when the desired golf course name is picked on the screen of FIG. 7F or 7H, the host 1 reads the initial screen of the golf course (hereinafter, this screen is referred to as the home screen), and the corresponding voice The processor 6 is instructed to read. As a result, for example, as shown in FIG. 8A, a screen for introducing the outline of the selected golf course such as history from establishment, characteristics of the course, fee, etc. is displayed, and the landscape and other explanations are repeated by narration. . At this time, the menu 30 is also displayed at the same time. It should be noted that the character string and the simple pattern such as the explanatory text may be generated from the character generator 2 instead of being recorded as a still image in the image CD-ROM.

When the course status of the menu 30 is selected, the "course status" column is colored red and the screen changes to the next screen. This red coloring can be performed by recording a red pattern in advance on the image CD-ROM, reproducing the pattern, and overwriting at the position of "course condition". Although not shown in the next screen, for example, aerial photographs of all holes of the golf course, illustrations thereof, and the like are displayed, and hole numbers are displayed in each hole. The hole number displayed on the aerial photograph is the number from 1 to 18 in the image C
This is performed by recording it in a D-ROM, reproducing it, and overwriting it. This number can be reproduced in a short time because of its small capacity.

Then, the hole number on the screen, for example, 6
When the No. 2 hole is selected, the host 1 first instructs the processor 6 to reproduce a black window of a predetermined size, and then the LDP.
3 is instructed to reproduce the moving image for introducing the hole, the wiper 4 is instructed to extract the moving image, and the processor 6 is instructed to reproduce the base screen. As a result, the screen shown in FIG. 8B is displayed on the display device. That is, a base screen including an illustration image of the selected 6th hole is displayed in the area 31 and a moving image reproduced from the LDP 3 is displayed in the area 32.
For example, a moving image introducing the situation from the tee ground to the green of the sixth hole is displayed. 33 is a menu for returning to the home screen of FIG. 8A. Further, as shown in 34, a menu for introducing holes is displayed, but in the present embodiment, a moving image for introducing holes is forcibly displayed when the course status is selected on the home screen. At this time, the column of the menu 34 is colored red. This process is performed as described above. At this time, the host 1 also instructs the LDP 3 to output only the audio channel of the course introduction. As a result, the user can clearly understand the characteristics of the hole and the like by the moving image and the sound. When the professional advice menu 35 is selected on the screen of FIG.
The DP3 is instructed to play back a moving image and audio that introduces how to attack the hole. As a result, professional advice such as cautions when attacking the hole is displayed in the area 32 of FIG. 8B.

Reference numeral 36 in FIG. 8B is a VTR icon used when a moving image is displayed. As shown in FIG. 8C, a play button 40, a rewind button 41,
Fast forward button 42, stop button 43, pause button 44
Is displayed. When the LDP 3 outputs a normal reproduced image, the reproduction button 40 is colored red. Further, for example, when the fast-forward button is pressed on the screen of FIG. 8B, the host 1 detects it and instructs the LDP 3 to fast-forward. At this time, the fast-forward button 42 is colored red. The same applies to the other buttons. In the process of coloring this button in red, the red pattern may be reproduced from the image CD-ROM and overwritten at a predetermined button position, or each button may be colored in red as shown in FIGS. It is also possible that five types of patterns are written in advance in the overlay image development area of the plane memory and the corresponding pattern is overwritten in the base image area according to the pressed button.

And when the way of life is selected,
As shown in E, the color is reversed. The same applies to the other menus, which are displayed in reverse color as shown in FIGS. 9F and 9G. This color reversal display is performed by reproducing these patterns from the image CD-ROM in advance and writing them in the overlay image development area of the plane memory, and by overwriting them at a predetermined position in the base image area as necessary. .

An area 55 in FIG. 9C is an area in which a menu for instructing the display method of the display content selected in the area 54 is displayed. For example, as shown in FIG. 9H, a video tape icon and a book icon are displayed. To be done. Then, when the book icon is selected, the host 1 instructs the decoder 8 to perform color reversal display of the icon as shown in FIG. 9J and reproduces the explanatory text corresponding to the content selected in the area 54. To the processor 6. The reproduced description is displayed in area 56 of FIG. 9C. At this time, it is clear that the narration with the same content may be performed, and that the character string of the explanatory text may be generated from the character generation device 2. In addition, the color inversion display of the book icon is
The pattern of FIG. 9J is written in advance in the overlapping image development area, and the pattern is overwritten at a predetermined position in the base image area. The same applies to the video tape icon.

When the videotape icon is selected in the area 55, the host 1 instructs the decoder 8 to perform color reversal display of the icon, display of the VRT icon and display of a black window, and to the LDP 3 as well. Instructing the reproduction of the moving image and sound corresponding to the content selected in the area 54, for example, the life of the animal, and the image to be extracted to the wiper 4. As a result,
As shown by K, a moving image showing the life of the animal is displayed in a predetermined area 58 of the display screen, and a VRT icon shown in FIG. 8E is displayed below the moving image.

When the moving image ends, the area 58 and the VTR
The icon is erased, and the moving image and the still image of the portion hidden by the VTR icon appear. At the same time, the videotape icon that was highlighted in color is returned to the original display state. Needless to say, these processes are performed by the host 1 by referring to a tree file or the like.

There are various methods of displaying the menu or icon other than the above-mentioned method. If the still image or the menu or icon can be reproduced at high speed from the image CD-ROM, the method described above is used. It is not necessary to write the menus and icons in advance in the overlapping image development area of the plain memory, and a desired pattern may be reproduced in real time from the image CD-ROM. Furthermore, it is possible to perform data compression when recording moving images and still images. Furthermore, when the capacity of the superimposed image expansion area of the plane memory of the decoder 8 is small, two base image areas are secured, and the base image currently displayed on the screen is written in one of them.
On the other hand, it is possible to write the base image used in the next screen in advance so that the screen can be switched immediately. Further, although the mouse is used as the pointing device in the above embodiment, a touch panel may be arranged on the front surface of the screen of the display device.
