In an electronic filing system configured like this,
Documents, drawings, etc. are input as image data from the image input/output device 10 and stored in the magnetic disk device 30. If you want to know the contents of the saved image data,
When you input a key from the keyboard 22 that corresponds to the image data you want, the processor card 71 searches for information, finds the desired image data, and displays it on the CRT.
21 will be displayed on the screen. Then, if necessary, the image data displayed on the CRT 21 is printed out by the image input/output device 10.

Further, the display state of image data is stored as follows.

The display state storage unit 80 has a function of storing the display state when image data is displayed on the CRT for the first time. The items to be stored include rotation, enlargement, scrolling of the displayed image in the vertical and horizontal directions, and inversion of the black and white state of the image, which are related to the image data display operation. The storage method can be specified by key operations on the keyboard while the image data is displayed on the screen.

Two types of display state storage functions are available.

That is, there are two types of functions: a function that stores each page of a document stored as image data, and a function that stores the display state in the terminal of the CRT display device 10 regardless of the page of the document.

The former function is a document-compatible initial display state function (hereinafter referred to as a document-compatible memory function).
The latter function is a terminal default initial display state storage function (hereinafter referred to as terminal correspondence storage function).

In the case of a document for which the initial display state has not been set, the multi-screen display state is set by the terminal compatible storage function. Further, for a document for which an initial display state has not been set, the screen display state is set by the document corresponding storage function in preference to the terminal corresponding storage function.

The operation of storing display states using the terminal-based storage function and the document-based storage function will be described below.

The operation of storing the display state using the terminal compatible storage function is performed as follows.

When displaying image data of the same type of format on a CRT screen through a series of image data search operations, it may be desirable to set the image data in a position where it can be easily viewed.

In such a case, use arbitrary image data to position the CRT screen at an easy-to-see position and memorize the display state before performing the operation, and then display subsequent image data on the screen in the same display state. let A flowchart of such operations is shown in FIG. 4.

In the flowchart of FIG. 4, the display state is set using an image screen such as D1. Image screen D
1 may be arbitrary. On image screen D1,
For example, if you want to display the letter "A" enlarged in white, you can specify the rotation state, scroll the display position, specify the enlargement rate, and specify the black and white inversion state of the display screen by operating the keys on the keyboard 22. Then, the image screen is set as shown in D2. Here, when the display state memory key K1 provided on the keyboard 22 is pressed, the CRT
The display state displayed at this time is stored as the initial display state in the work file F1 of the terminal. This work file F1 is provided within the display state storage section 80.

From now on, when you press 1 on the display state memory key, CR
The image displayed at T21 is displayed in the display state stored by the work file F1.

The display state once set remains valid until it is set again. Furthermore, when a plurality of CRTs are connected to the system, different display states can be stored for each CRT terminal.

On the other hand, the operation of storing the display state using the document correspondence storage function is performed as follows.

When searching and displaying many types of documents continuously, there are cases where the desired display direction and center position of image data differ for each page of the document. In this case, if the display state is stored for each page of each document using the document correspondence storage function, operations can be performed quickly when referring to the document repeatedly.

Such operations will be explained using the flowchart shown in FIG.

In the flowchart of FIG. 5, an image screen E1 of a document whose initial display state is to be stored is displayed on the CRT by a search operation.

For example, if you want to enlarge and display the letter "B" in white on the image screen E1, you can specify the rotation state, scroll the display position, specify the enlargement rate, and invert black and white for the display screen by operating the keys on the keyboard 22. The status is specified and the image screen is set as E2. Here, press 2 on the display state memory key provided on the keyboard 22.
When is pressed, the display state currently displayed on the CRT is stored in the search directory file F2 as the initial display state. This search directory file F2 is provided within the display state storage section 80.

Such initial display state is stored for each page of the document.

From now on, when you press 2 on the display state memory key, CR
The images displayed at T21 are displayed in the display state stored in the search directory file F2 for each page of the document.

According to an electronic filing system configured like this,
The following effects can be obtained.

An easy-to-see display state of image data set by rotating, enlarging, etc. the display image is stored in the display state storage unit 80. Once the display state is memorized, from then on there is no need to repeat operations such as rotating or enlarging the displayed image.
By simply pressing the display state storage keys K1 and K2, the image data is displayed on the CRTK in an easy-to-see display state. Therefore, image data can be displayed on the CRT in an easy-to-read state with simple operations.

In the embodiment, the display state storage unit 80 specifies the rotation state, the scrolling of the display position, and the like for the display screen.
Although the case has been described in which the designation of the enlargement ratio and the designation of the black and white inversion state are stored, the display state storage unit 80
may store instructions related to other display states, such as changes in brightness from white to black on a gray scale provided on a CRT, designation of contrast, etc.

This allows image data to be displayed on the screen with easy-to-read contrast.

As described above, according to the present invention, it is possible to provide an electronic filing system in which image data is displayed in an easy-to-read state with a simple operation.
