Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen saver which is used to prevent a specific position on a display screen from continuously emitting light by displaying an image whose display position changes on a display screen of a computer. It is about.

[0002]

2. Description of the Related Art A display device which is one of interface devices between a computer main body and an operator includes a CRT.
(Cathode ray tube) is widely used. If the operator interrupts the operation of the computer for another task or the like, the image displayed on the display device is also fixed. CR
As for T, when a specific position on the display surface continues to emit light for a long time, a so-called burn-in phenomenon occurs in which an afterimage remains even after the display is stopped. Therefore, when the display image is fixed for a certain period of time or longer, it is desirable to erase the image in order to avoid deterioration of the display. However, if the image has disappeared, it is indistinguishable from a state in which the power of the computer is shut off, and an accident may occur in which data being worked on may be lost due to an erroneous operation.

In order to avoid this problem, when a display image on a display device is fixed for a certain period of time or more, the image is erased, and instead, an image that moves uniformly on the display screen is displayed. A screen saver is used to prevent deterioration of the computer and to indicate that the computer is operating.

[0004] Images displayed on a display screen by a conventional screen saver are those in which abstract figures change continuously, those in which figures and characters move so as to flow on the screen, cartoon characters and patterns. Animals were moving on the screen.

[0005] On the other hand, those sold as souvenirs or souvenirs at sightseeing spots include postcards and photo books depicting local landscapes and historic sites. Postcards have been popular since ancient times, and are sold at most souvenir shops in sightseeing spots. That is the fact.

1 to 3 show an embodiment of the present invention. FIG. 1 is a block diagram of a main part, FIG. 2 is an operation flowchart, and FIG. 3 shows a display mode. is there.

In the block diagram of FIG. 1, 1 is a display device, 2 is a keyboard, 3 is a mouse, 4 is a central processing unit, 5 is a bus (bus), 6 is an external memory such as a floppy disk or a hard disk, 7 is an internal memory. The interface circuit is omitted in the figure.
Further, the ordinary computer is provided with other peripheral devices, language drivers, application programs and the like not shown in FIG. 1, but they are omitted because they are not directly related to the present invention.

The display device 1 is connected to the bus 5 via an image memory 8 and displays an image based on data recorded in the image memory 8. The keyboard 2 and the mouse 3 are connected to the bus 5 via the input detecting means 9, and a signal from the input detecting means 9 is transmitted to a load / unload program provided with an OS timing means loaded in the internal memory. Provided as an interrupt signal. The currently executing program is recorded in the executing program area of the internal memory, and the stack area 11 is provided for storing the state of the interrupted program.

The photographic image data and the display control program recorded in the external memory form a main part of the present invention. The photographic image storage area 12 stores a plurality of photographic images related to a specific sightseeing spot or historic spot. Is recorded. This is recorded, for example, by reading a photograph taken for a postcard with a film scanner or the like.

In the storage area 13 of the display control program,
A program for transferring one of the plurality of pieces of photographic image data stored in the photographic image storage area 12 to the image memory is recorded. This program includes a sequential or random selection unit, a random number generation unit, and a display position calculation unit. , A timing generating means and an image switching means. The sequential or random selection means can be constituted by a counter for repeatedly counting the number of photographic image data when the number of recorded photographic image data is N, or a random number generator having N output values. The display position calculation means calculates the X and Y coordinates on the display screen based on the output value of the random number generation means, and calculates the display position of a photographic image smaller than the display screen (for example, a postcard size). As a calculation method, a position for displaying the center of the photographic image is calculated as XY coordinates on the display screen based on a signal of the random number generating means, and when the photographic image is displayed at that position, the photographic image is displayed on the display screen. When you run out of
A method in which the coordinates are moved to the center side of the display by the amount of protrusion, and a method of outputting the XY coordinates within a range in which the photographic image does not protrude is determined in advance, and the XY coordinates in the range are determined based on the output of the random number generation means. A calculation method or the like can be adopted. The former method illustrated has a higher probability that a photographic image will be displayed at the periphery of the display screen, and the latter method has a higher probability of being displayed at the center. Preferably, the two methods are compromised so that the images are uniformly displayed on the display screen. The timing generating means generates a timing output at a fixed or random time interval within a certain range, and the photographic images sequentially or randomly selected by the random selecting means are calculated by the display position calculating means according to a command of the timing generating means. Is transferred to the image memory 8 of the display device by the image switching means.

The above-mentioned photographic image data and the display control program are essential parts of the screen saver of the present invention, and a recording medium such as a floppy disk or CD-ROM in which these data and the program are recorded is stored in an electronic computer. , The screen saver of the present invention is configured.

Next, the operation of the screen saver of the present invention will be described with reference to FIGS. When the operator is operating the computer, the program of the application to be operated is loaded in the running program area of the internal memory. When the operator stops the operation of the keyboard 2 and the mouse 3 for a predetermined time (X time in FIG. 2), the timer of the OS times out, the load / unload program is operated, and the state of the operating application program is changed to the stack area 11. After that, the display control program is loaded into the program area being executed. The display control program loaded into the program area under execution selects the first one of the plurality of pieces of photographic image data by the selection means, positions the data at the display position calculated by the display position calculation means, and sets the timing. The data is transferred to the image memory at the timing specified by the generating means. Thereby, the display position and the display content displayed on the display device 1 are changed. As a selection means,
When a counter for repeating counting is used and the number of pieces of photographic image data is set to eight, the counter is reset to 0 each time the counter reaches eight, and eight types of displayed photographic images are sequentially switched. The position of the image to be displayed is calculated every time the display is switched based on the random number, and thus is not fixed. FIG. 3 schematically shows a state of a photographic image displayed on the display screen.

When the operator operates the keyboard 2 or the mouse 3 while the photographic image is being displayed on the display screen while being switched, the signal is given to the load / unload program of the OS, and An interrupt operation is generated, the display control program in the running program storage area is erased, and the program and data saved in the stack area 11 are returned to the running program area. As a result, the display screen of the display device 1 becomes It returns to the display screen when the operator interrupted the operation.
