Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for storing / reproducing an image displayed on an image output device.

[0002]

2. Description of the Related Art Conventionally, in order to save an image displayed on a display (image output device) of a computer and display it again on the display, image information is saved individually for each business program that outputs each image. And had to create a process to reproduce.

Further, there is a function called "hard copy" as a technique relating to copying of an image displayed on a display. The “hard copy” is a function of printing out an image displayed on the display of a computer from a connected printer device.

[0004]

Assuming that each business program has an image saving / reproducing function as a function, an image saving / reproducing function is created for each business program corresponding to each screen. Must be incorporated.

Further, even if the image storage / reproduction processing is incorporated in each business program,
As long as the process is one process equivalent to the other processes in the program, this function cannot be used at any timing during the execution of the business program. In other words, even if a failure occurs during the execution of the business program, the execution of the program must proceed until the image data saving process, and therefore the screen cannot be saved as it is.

Next, regarding the "hard copy" function,
Depending on the point that it cannot be used on a computer to which a printer is not connected and the characteristics of the printer, a color image may be printed in black and white, or the shape of the graphic may be distorted.
There are drawbacks such as long processing time.

It is an object of the present invention to save image data even if a failure occurs during execution of a business program, and to save / reproduce an image displayed on a display even in a computer to which a printer or the like is not connected. It is to provide a screen saving / reproducing method.

[0008]

In order to achieve the above object, a computer screen saving / reproducing method of the present invention uses an image display information saving file for saving image information and a main storage device. An image storage program that outputs image information to the image display information storage file, an image reproduction program that reads image information from the image display information storage file and outputs the image information to an image display area in the main storage device, and a power supply of the computer main body. It has an image saving program execution function capable of starting and executing the image saving program at an arbitrary time.

[0009]

Therefore, the image information can be saved / reproduced at any time, and the image displayed on the display can be easily saved / reproduced even in a computer to which other peripheral devices such as a printer are not connected. ..

[0010]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is an overall configuration diagram showing an embodiment of the present invention.

An image display information area 6 for storing image data displayed on the display 2 is provided in the main storage device 4 which constitutes the computer main body 1. The image display information storage file 9 for storing image data in the auxiliary storage device 5 and the image data in the image display information area 6 in the main storage device 4 are stored in the image display information storage file 9. And an image reproduction program 11 for reproducing the image data stored in the image display information storage file 9 in the image display information area 6.
And are provided. Further, the basic software in the main storage device 4 is provided with an image saving program execution function 8 for activating and executing the image saving program 10 at an arbitrary time including during execution of a general business program.

Next, the operation of this embodiment will be described. 1. Setting example When the function key and the print key of the keyboard 3 are pressed at the same time, the image storage program execution function 8 suspends the execution without changing the data and screen of the business program, executes the image storage program 10, and then executes the business again. Return control to the program. The image reproduction program 11 waits for a key input after the image is displayed, and when any key is pressed, the screen is initialized and the program ends. 2. Example of image saving operation When the user is performing a certain task and wants to save a certain screen state for later reference, the function key and the print key of the keyboard 3 are pressed at the same time.
As a result, the image saving program execution function 8 operates,
The image storage program 10 is executed, and the image data in the image display information area 6 is stored in the image display information storage file 9. At this time, since the data and screen of the business program being executed do not change, the user can continue the business as soon as the control returns to the business program. 3. Example of Image Reproduction Operation When it is desired to reproduce the previously saved screen, the program name of the image reproduction program 11 is input in the state of waiting for the command input of the computer (waiting for the execution program name input). As a result, the image reproduction program 11 is executed, and the image data stored in the image display information storage file 9 is stored in the image display information area 6 and displayed on the screen.
After that, the image reproduction program 11 is waiting for key input, and when any key is pressed, the screen is initialized and the program ends. This puts the computer back in wait for normal command input.

[0014]

As described above, the present invention has the following effects by having the image display information storage file, the image storage program, the image reproduction program, and the image storage program execution function. (1) Image information can be saved and reproduced at any time. (2) Even in a computer to which other peripheral devices such as a printer are not connected, the image displayed on the display can be easily saved / reproduced. (3) Also, since the image information is stored in the same format as a general data file, it can be copied to a floppy disk or the like and carried, or transmitted online to the same type of computer in other locations. You can also reproduce the image with.
