Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen saver, a screen saver display data management system, a simple image data base and a display screen security system,
To be more specific, while the normal work is stalled for a required time on a personal computer or the like, a still image (main image or logo sub image) window and a moving message (telop) window are simultaneously displayed on the required CRT display screen screen. Then, the music or voice is output at the same time, and after the required display time of one still image window has elapsed, the next required still image window is automatically switched and displayed, and the image on the CRT display screen is displayed. It is necessary to prevent burning of a part or the whole due to an afterimage, and at the same time to make the still image window and the moving message window have a function as an advertising medium, and to keep the still image window free of motion. CRT display screen A screen that prevents the phenomenon of image sticking due to afterimages on the screen. Ba, the display data management method of a screen saver, on a simple image data base and the display screen confidentiality scheme.

[0002]

2. Description of the Related Art A screen saver has been proposed which prevents a burn-in phenomenon due to an afterimage of an image on a CRT display, which occurs when a computer screen displays the same screen for a long time.

For example, in the flow chart showing the operation of the conventional screen saver shown in FIG. 8, a signal is generated from an input device such as a key board or a mouse connected to a computer at a step on a normal business screen. Check the key buffer to see if it is present, and if no signal is generated, measure the elapsed time in step.
If the elapsed time exceeds the set arbitrary time in the judgment at the step, the process shifts to the screen switching from the next step.

After the screen data under operation is saved in the memory in the step, it is erased, and the screen
Display the programmed image in the saver. Small desired character (about 10x10-40x4
There is something that moves the 0 dot, etc. in an animated manner to prevent burning of the CRT display and at the same time visually entertains the user.

While moving the character, it is checked in step whether a signal is generated from the input device, and if it is generated, the image is erased in step and the work screen data saved in step is immediately deleted. Since it is restored, it does not have any adverse effect on daily operations.

[0006]

However, the type of the character, the number of movement patterns, etc., is the capacity of the program providing medium of about 1 to 2 floppy disks (1.2.
There is a limit when trying to narrow down to 2.9 Mbytes), and the time required for the user to finish viewing all types and all patterns is at most 1 to 2 hours. If you want a screen saver with a different image and want to put your own image in the screen saver, the display data is described at the program source level, so you are not the developer of the program. After all, it is impossible to add or change.

Most of the clean savers incorporate famous characters in the display data in order to promote the increase in the number of characters sold, but this is required for programming because the movement of the characters is to be characterized. The development period is long, and the number of contractors who can contract in a short period of time is limited, so even if we wanted to adopt it for display data, we could not meet the appearance cycle of famous characters.

Further, the known screen saver has a function of masking data or sentences which cannot be seen by people outside the company by the display data. However, the screen saver does not operate until the set time elapses after the work is stopped. Since it did not start up, it did not work completely as a display screen confidentiality protection method (masking).

In order to solve the above-mentioned deficiencies of the screen saver of the known CRT display, the present invention enables the user to easily add or change the display data, and the famous character can be displayed in a short time. Even when a plurality of data appear, they can be immediately incorporated as display data. Furthermore, a screen saver with a complete masking function, a screen saver display data management method, a simple image data base, and a display screen confidentiality protection method are available. It is provided.

[0010]

SUMMARY OF THE INVENTION In the present invention, a natural still image in a standard bitmap file format in which a display image does not have a motion and a telop (character in a text file format having a motion in a fixed direction) are used. ), And 3 types of music data in wave file format corresponding to each screen are stored in a different directory in a different file from the program, and after a business stagnation due to a specific key operation set in the environment setting function. It is characterized by having a function to forcibly activate the screen saver regardless of the elapsed time.

Further, the handling display data is a natural still image, so that a simple image data base function capable of more effectively utilizing the screen saver data is provided.

[0012]

In the screen saver according to the present invention, since the program and the display data are separate files, the file structure is easy to understand, and the file to be updated and the file not to be updated can be easily distinguished. Become.

By adopting the standard file format for all three types of files of images, characters and music, data created by utilizing various utilities (for example, image utilities, text editors, wave editors) can be stored. It can be used as it is as screen saver display data.

Furthermore, since the screen saver can be instantly forcibly activated and immediately terminated by a key operation that allows the user to set separately, the security of important documents on the computer screen can be instantly protected.

In addition, since various types of data are managed in a relational database basis for each group, a plurality of reduced images (15 screens) can be intuitively selected with a single key from the image menu displayed simultaneously. It can also be used as a simple image data base that can be indirectly searched from key words.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the screen saver according to claim 1 is shown in the accompanying drawings will be described. This screen
In FIG. 1 showing a flow chart of the saver, a main memory resident interrupt program (Terminate)
and Stay Resident program
m, TSR) from the normal work screen 10 of the required computer (not shown) to the console input determination step 12 and the elapsed time measurement step 14 to the determination step 16 of elapsed time and set time.

The determination step 16 is the normal business screen 1
It returns to the midpoint of 0 and the console input determination step 12.

Next, step 18 for saving the work screen to the memory, step 20 for searching / confirming the display image, step 22 for reading / displaying the display image, step 24 for reading the telop on the screen, step for calculating / displaying the telop display position 26, music / voice reading / display step 28, image display time measurement step 30, console input determination step 32, elapsed time, set time determination step 34
And the determination step 34 is performed by searching the display image.
The process returns to step 20 where the decision is made.

The console input determination step 32 is connected to a display screen deletion step 36 and a saved screen display step 38, and the display step 38 is displayed on the normal business screen 10 via a measurement elapsed time clear step 42. Then, the other end of the console input determination step 12 is connected to the measured elapsed time clearing step 42.

Referring again to FIG. 1, the steps 10-18
Is a place to judge whether or not to activate the screen saver during execution of normal work, and to judge whether to return to normal work from the screen saver in the console input determination step 12 or the display screen. Erase step 3
6. The processing for returning from the screen saver to the normal operation in the step 38 of displaying the saved screen and the step 42 of clearing the measured elapsed time is the same as that of a known screen saver.

As described above, the steps 10 to 16 are a part of the screen saver program that constantly monitors whether or not the work is stagnant even during the normal work. This program is a main memory resident type, and the resident type adopts the TSR method described above. ".EX
It has the form of an "E" or ".COM" file and when the program is executed, only the interrupt controller is loaded into the main memory and terminated without leaving the memory resident. Most other programs are kept on the hard disk and loaded only when an interrupt occurs to minimize main memory consumption.

The program resident in the main memory is a key (keyboard / mouse), timer, display, console input determination step 12 for VSYNC interrupt (determines whether console input is made by various interrupt monitoring programs 12) and elapsed time measurement. Step 14 (timer measurement program). Here, the VSYNC interrupt is an abbreviation for a sync signal and is used for screen control and the like. When data is output to the port 64H, a vertical blanking synchronization signal (interrupt signal) is generated every 1/60 seconds, and the interrupt signal is used to forcibly execute the program at regular time intervals (minimum 1/60 second). Can be transferred to the interrupt monitoring program.

The interrupt monitoring program constantly monitors the status of key (keyboard / mouse) input and console (display) output in the console input determination step 12, and if there is no change from the status at the previous interrupt, then the elapsed time. The time is measured by the timer in the measuring step 14.

The time measured by the timer measuring program of the elapsed time measuring step 14 is compared with the set time, and if the measured time exceeds the set time, the process proceeds to step 18, otherwise the step 10 Return to normal business.

As a result of the judgment in step 16, if the elapsed time exceeds the set time, the process proceeds to step 18 to save the current work screen on the memory and erase the screen.

Search for data to be displayed in step 20
Determine. The data used in the program is
Records are managed by the base function. 7 and 8 show the setting fields of the main master file. Image data (.BMP file), text data (.T
An XT file) and music / audio data (.WAV file) are registered as one data in one record of the data master. Further, the set of records of the data master is registered as one group master record.

The association between the masters is realized by putting the same code in the "group code" field of each master. Same group master
The number of codes that can be specified depends on the capacity of the hard disk (1 partition, 1 directory). When starting the screen saver, specify one record of this group master.

The image file displayed in step 22 is stored in a VRAM (Video Random-om Access).
Memory, video RAM), and open a window after the currently displayed image (bottom layer) to draw. When the drawing is completed, the uppermost window is erased from the screen in a fixed pattern, and the previous screen data in the VRAM is discarded when the image of the lowermost layer appears on the screen. One image is made up of two windows, a main image and a logo sub image. Since the main image is displayed in the lower layer window and the sub image is displayed in the upper layer window, it is always the most suitable window for a logo or the like to be displayed in the uppermost layer.

The image erasing patterns include a pattern for moving or reducing in the arrow direction as shown by 1 to 6 in FIG. 4, and a pattern for erasing in the arrow direction in units of blocks of a certain size like 7 and 8. As shown in 9, the color palette is manipulated and the pattern is roughly divided into three patterns that gradually disappear.

The resolution is, for example, 640x400 dots peculiar to NEC98 series to standard VGA 640x480.
Dot, SVGA800x600, XGA1024x7
68/1120 x 750 dots, 16 colors, 256
In addition to colors, it also supports full-color display of 32,000 colors and 16.77 million colors. If the device does not support SVGA, the image is reduced and displayed (640x400 / 64).
A part of the top, bottom, left and right is omitted for display with 0x480 dots).

In step 24, the telop file determined in step 20 is read, and in step 26, the telop display position is calculated and displayed. To move the telop, a dedicated window is secured and the window body is moved. However, if the reserved window is opened exclusively for characters, rewriting will be performed character by character when the window is moved, resulting in awkward movement. It is said that the number of characters that can be set on one screen for use depends on the free space on the disk. However, if the windows for all the set number of characters are rewritten at once, the rewriting process is not displayed on the screen. Since it is performed up to, the processing becomes very heavy.

There is no problem in the case of a computer having a very high CPU power (for example, Intel-based 486DX class or higher, manufactured by Intel Corp. in USA) and a high processing speed, but the specifications of the equipment used differ depending on the user. Therefore, there is too much difference in movement between high and low processing speeds. Under the current situation where the CPU of Intel 486SX class (made by Intel Corporation in the United States) is most widely used, even if the computer has a slow processing speed, the problem as described above can be solved. Reserved for images.

Unlike the case for characters, the movement in dot units is possible, so that the appearance and disappearance on the screen are smooth. Further, since the processing for the image window becomes heavier for the image window and the character window, the clipping processing used in the CAD system or the like is applied here. This is a processing method that, if the drawing position is outside the view port window (display screen) as a result of calculating the next movement for one image, remove it from the drawing processing target and make the drawing processing as light as possible. Is.

The telop set for further narrowing the target range of the clipping image processing is divided into 100-byte units so that the drawing calculation can be started, and no matter how many bytes the text is set, the telop is processed. The speed can be kept constant in 100-byte units.
Therefore, even in a model having a slow CPU clock frequency, text can be smoothly flowed in a desired direction on the screen.

In step 28, various utilities (wave format (.WAV) music / speech files created by a sound recorder, a wave editor, etc. are read and played. Sounds installed in the computer used by the user, etc. Since the function of the board is different, do not edit during playback or change the music / voice characteristics in the file.
The command to be transmitted to the sound board is limited to the start and end of reproduction, and the reproduction result of music / voice is not different depending on the characteristics of the sound board.

In step 30, time ² during which one image data is displayed is measured. In step 32, it is judged whether or not the normal operation is resumed by checking the key buffer, and if any data is accumulated, the process proceeds to step 36. Without data, goes to the step 34, returns to step 20 If the measured time ² by comparing the time ¹ is set as the time ² measured in step 30 does not exceed a set time ^1, it has not exceeded Step 2
Go to 6.

The above-mentioned embodiment is an operation flow chart of the burning prevention function or the confidential document protection function, and FIG. 2 shows an operation flow chart as a simple protection data base. In step 50, the registered images are reduced and a plurality of (15 screens) are displayed on the menu screen. Even if the registered image is full color, the menu screen automatically reduces to 256 colors using the standard palette, and the size is reduced so that the aspect ratio does not change.

When the page command is selected in step 50, the process proceeds to step 54, when the key word input is selected, the process proceeds to step 56, and when the direct image is selected, the process proceeds to step 2.
Move to 0. Direction selected in step 54 (previous page /
It is checked whether or not a page exists on the (post-page), and the corresponding image is selected in step 58 and displayed in the menu of step 50.

When the key word is selected in step 52, the key word input is similarly prompted in step 56, the corresponding image is selected in step 58, and the process returns to step 50 to display it on the menu.

When the display image is determined by changing the page or searching by the key word, the reduced image displayed in the menu is clicked with the mouse, or the return
It is selected only by pressing the key, and the operation similar to that of the screen saver after step 20 is started.

The screen saver inspects the presence / absence of a key input even while displaying an image, and immediately returns to the normal business screen when the input is made. However, in the simple image data base, the screen is displayed for a purpose. So, instead of returning with every key input, the menu displayed in the corner of the image
By selecting the button, the process returns to step 10.

FIG. 3 shows a flow chart for returning the operation of the display screen security system (masking system). In step 70, all the types of keys pressed on the normal job screen in step 10 are checked. If they match the set forced activation key, in step 72 a flag (FL
G) is set and the operation of the screen saver after step 18 is started. If the keys do not match, the flag (FLG) is cleared in step 76 and the normal work screen in step 10 is returned to.

In step 74, the type of the key pressed during image display in steps 18 to 30 is checked, and if it matches the set forced termination key, step 36,
In 38, the screen is restored, and in step 76, the flag (FL
Clear G). The forced start key and forced end key are
Different keys can be set for multiple combinations.

【The invention's effect】

(1) As a screen saver; a mobile message (telop) while a normal work is stopped for a required time on a computer having a CRT display screen
The function is turned off (no display or output), the sound function (music or voice) is turned off, and the still image (main image or sub image for logo) window is displayed. ) The windows are sequentially and automatically switched to be displayed to prevent partial or entire image sticking due to an afterimage on the screen of the CRT display screen.

(2) As a bulletin board; The mobile message (telop) function is turned on (displayed), and each individual's schedule, going-out destination, return time, etc. are set in the display text, and afterimages are displayed on the CRT display screen. Preventing partial or complete burn-in, at the same time use as a personal bulletin board.

(3) As a demonstration: Turn on (display and output) the moving message (telop) function and turn on the sound function to display the product description, store name, contact information, etc. in the display text and BGM. Set to sound and show the company logo etc as a sub image
At the same time to prevent the burning of the display in the room,
Make a demonstration.

(4) As a product catalog; the moving message (telop) function and sound function are turned on (displayed), the store name, contact information, etc. of the store are set in the display text, and the product description by voice is set in the sound. Then, set the catalog, logo, etc. in the logo sub-image and distribute it as a product catalog.

Since it is possible to create data at a low cost earlier than creating one type of advertisement such as a pamphlet, data of still images, logos, telops, music, etc. are adopted, so that it is possible to -It can be used as a saver and also as an advertising medium.

(5) As an advertisement / advertising medium; a beautiful picture such as a landscape or a photograph is put in the main image, a company or group logo is put in the sub-image, and it is distributed on the screen saver as an advertisement / advertising medium. I can. The screen saver method according to the present invention is a data method that can handle most of the applications on the market. Import bitmap files from peripherals such as image scanners, video drivers, CD-ROM drivers, etc. from media such as photographs, films (both negative and positive), catalogs, pamphlets, videos, etc. It can be handled as a saver image.

(6) As a simple image data base; when a large amount of data is created as a product catalog, it is inconvenient if it is used as a screen saver because the image to be displayed cannot be selected. When it is desired to select and display an image, it may be activated as a simple image data base and selected from the menu or selected / searched by a key word and displayed. Images registered in the menu can be reduced to display up to 15 images on one screen, and if you turn the page, you can additionally register according to the capacity of the hard disk.

Not only can the page be searched by the human eye while turning the page, but by inputting or selecting a key word, the corresponding screen can be instantly selected by the database and displayed on the menu. Therefore, even if a large amount of image data is registered, the target image can be displayed without spending time for searching.

Similarly, for telop and music / speech, a text file created by an editor or a word processor is used as a telop as it is, and a wave file obtained by digitizing a real voice etc. by blowing it from a cassette tape, a CD, or a microphone is directly played as a music. / Can be captured as audio by this screen saver. Therefore, the data can be corrected easily, quickly, and inexpensively, and can be utilized not only as an application called a screen saver but also as a public notice medium for a company on a computer.

By making the program and the display data separate files, the file structure is easy to understand, and files to be updated and files not to be updated can be easily distinguished.
By adopting the standard file format for all three types of files of images, characters, and music, the data created using various utilities, text editors, wave editors, etc.) can be directly used as screen saver display data. Since it is characterized by being able to handle it, you can easily become familiar with the purchased screen saver.

Since it is possible to forcibly start and forcibly terminate by a key operation that can be arbitrarily set by the user, it becomes possible to instantly protect the confidentiality of important documents on the computer screen. "CTRL" + "BS" + "f.1" for the forced start key
"0", "SHlFTi +" TAB "+ for the forced termination key
Assign a complex combination of keys such as "HELP", or use "SHIFT" + "TAB" + for the forced activation key.
