[Effect]

In the display device according to the present invention, background image information in which pattern information indicating an information display position created according to the procedure written in the first memory is written, and a second memory in which other information such as figures and characters are written are provided. The storage contents of the memory are set as image information for one screen, information is read from an arbitrary storage area of the second memory, and graphics and characters are scrolled and displayed on the display screen together with a background image within a window.

(Example) Hereinafter, an example of a display device according to the present invention will be described in detail with reference to the drawings.

In the embodiment shown in the block diagram of FIG. 1, the data input section l provides various input data such as cursor operation data, character data, or control l data to the control section 3 via the input control section 2. It consists of a keyboard, mouse, etc. operated by a person. The human power control section 2 receives the human power data from the data input section 1 periodically or when requested by the data input section 1 and sends it to the system (1 section 3).

When a document display request is made through the operation of the data input unit 1, the control unit 3 first performs the process according to this embodiment based on the background image information creation procedure information written in the screen information memory 4 in advance. The maximum size of one page of a document displayed on the display screen of the display unit 10 in a display device is, for example, A.
Background image information is created that depicts a background image with a pattern that is larger than the size (4 sizes) and serves as a mark indicating the information display position of the document, and its pixel data is written into the screen preparation memory 5. Here, as schematically shown in FIG. 2, the pixel data of the background image information of the image 51 of the desk with the grid pattern 50 as a mark indicating the information display position of the document is set to white as "O". 0 written into the screen preparation memory 5 as black rlJ Next, the control section 3 reads out one portion of document information from the document memo I76, and converts the pixel data of the document image 53 into the pixel data schematically shown in FIG. It is written into the screen preparation memory 5 as shown. Here, the window area 53 from which pixel data is read from the screen preparation memory 5 can be arbitrarily specified in position and size on the display screen of the display unit 10 by Kuwa Saku of the data input unit 1. It has become. Further, the control unit 3 controls the display unit 10 to control the display unit 10 at the same position as the pixel position of the window on the display screen of the screen memory 7, which has a memory cell corresponding to the pixel on the display screen of the display unit 10. The pixel data of the image to be displayed in the above-mentioned slide is read out from the preparation memory 5 and written as shown in FIG. At this time, the control section 3 uses the shift register 8 to perform a bit shift process to align the pixel data read from the screen preparation memory 5 to the structure of the byte data at the display position in the screen memory 7.

Then, an image based on pixel data read out from the 1iIiii image memory 7 via the flJ control section 3 is displayed on the display screen of the display section 10 by the display control section 9.

Here, the background image 51 in the screen preparation memory 5 is
position origin data (DX, Dy) and data indicating its size (Dh, Dw), position origin data (Bx, By) of the document image 52 in the screen preparation memory 5 and data indicating its size (Bh , Bw), a window area 5 for reading out pixel data from the screen preparation memory 5.

y) and data indicating its size [Oh, Ow] and other various control data are written in the image information memory 4 in advance.

Then, when in-window scrolling display is designated by the operation of the data input section 1, the control section 3 controls the display on the screen preparation memory 5 based on each insertion control data written in the image memory 4. The window opening 53 is sequentially moved by a predetermined scroll width in the specified scroll direction, and the pixel data of the window area 53 is sequentially transferred to the screen memory 7. For example, the position of the window area 53 on the screen preparation memory 5 is
Each pixel data is sequentially moved from a window area 53A indicated by a broken line in the figure to a window area 53B indicated by a chain line, a window area 53C indicated by a point tM11, and a window area 53C indicated by a thin solid line to store each pixel data in the screen memory. 7, (A) and (B) in FIG.

As shown in (C) and (D), a window image 70 in which the document image 52 and the background image 51 are superimposed is scroll-displayed on the display screen of the display unit 10. In the window image 70 that is scrolled in this way, the edges of the document image 52 can be recognized by visually checking the state of the background image 51. Using the pattern 50 as a landmark, the position of both document images 52 relative to the overall layout can be recognized. 5 and 6 above, the window image 7
Although the vertical scrolling display of 0 is shown, (A) in Fig. 7,
