It includes an image processing circuit 36 that reads received data from the AMI and creates a display image, and a controller/driver 37 that causes the display 3 to display the created display image.

Next, the operation of this embodiment will be explained.

At the time of reception, the received data that has entered the modem 26 through the telephone line is stored in the data RAM 35 as compressed and coated data.

After the reception is completed, one page of received data is read from the data RAM 35, converted by the CEP circuit 28, and expanded into the video RAMI.

Then, the display control means 2 reads data from within the video RAMI, creates a display image based on the display mode specified by the operation means 4, and displays it on the display body 3.

Next, designation of the display mode for displaying the display image on the display body 3 will be explained.

First, the relationship between the decomposition ability of received data and the decomposition display ability of the display 3 will be explained. 63 of facsimile communication
Received data according to the standard is 216mm wide and 290mm long.
In the case of an A4 size original, the width direction is 1728 dots (8 dots/mm), and the vertical direction is 1117 dots (7.7 dots/mm).
mm) or 2233 dots (3,85 dots/+++
+n) resolution capability. On the other hand, the display body 3 is
For example, a liquid crystal display with a width of 211 mm and a height of 66 mm, which is currently widely used in word processors, has a horizontal dot of 640 dots (3,03 mm).
It has a resolution display capability of 200 dots (3.03 dots/mm) in the vertical direction. Therefore, it can be seen that the decomposition display ability of the display body 3 is rough compared to the decomposition ability of the received data.

Therefore, as shown in Fig. 4 for an A4 size original, the display body 3
If the display mode is specified so that approximately the width of the document is displayed within the screen frame A, the person checking may not be able to visually check fine characters. However, if the text on the document is large and can be visually confirmed, specifying this display mode will allow a larger area of the document to be displayed at once, which will be useful when displaying the document in separate sections as described below. This has the advantage of reducing the number of divisions.

On the other hand, if the characters on the document cannot be visually confirmed in the display mode described above, specify enlargement of the display, for example, enlarge the screen frame A1 shown by the broken line in Fig. 4. This allows you to check even if the characters on the document are small.

Therefore, the user can use the operating means 4 to specify the magnification that is most convenient for viewing. Note that the simplest method for changing the reduction magnification is to remove part of the data and display it, but in order to display with better quality, image processing should be performed.

The document is displayed in parts as shown above, and the display area within the document can be moved and viewed. That is, the screen frame A shown in FIG. 4 can scroll the document in the vertical direction, and the screen frame A1 can scroll the document in the vertical and horizontal directions.

Also, if the original sent from the sending side is upside down, upside down, or facing sideways, the video RAM
When reading data from I, the erect state can be corrected by changing the scanning direction of the address bus of the video RAMI.

That is, as shown in FIG. 4, when the original is in the normal direction, it is read out sequentially in the direction of arrow a, but when the up-down direction of the original is reversed, it is read out sequentially from the direction indicated by the arrow. Similarly, if the original is facing horizontally (the original is horizontally facing the screen frame A2 indicated by the two-dot chain line in Fig. 4), it can be displayed in the direction of arrow a or By reading out sequentially from the direction of arrow C, the images can be rotated and displayed.

As described above, it is possible to specify the display mode such as vertically inverting, rotating, scaling, and scrolling the display image of the document displayed on the display unit 3, and to display fine details such as characters written on the document. To correct the displayed image so that it is easy to see even if the display capacity of the display unit 3 is low and the characters cannot be seen, or if the document is oriented upside down or horizontally. I can do it.

Next, the function of the identification means 5 of the display control means 2 will be explained. As shown in FIG. 5, a marker M, for example in the shape of an arrow, is placed on the original on the sending side to designate the display mode as described above. Then, by the function of the identification means 5, the video R
When reading from the AMI, the mark M included in the received data of the original can be identified, and the orientation, magnification, etc. of the original can be automatically set and displayed. The method for recognizing this marker M is as shown in FIG.
The shape and size of the mark M are identified from the number of bits accompanying the scanning of the mark M placed at a predetermined distance from the mark M,
Identify the orientation of the document from its shape and the magnification from its size.

Next, the function of the discrimination means 6 of the display control means 2 will be explained. As shown in FIG. 7, there are cases where the content is written only in a part of the manuscript, and in such a case, the function of the discriminating means 6 allows the information area in the received data to be read out from the video RAMI. E can be determined, and a display mode can be automatically set and displayed according to the determination result.

In this method of determining information area E, when scanning a document, a portion where bits continue for a predetermined length is determined to be information area E. Note that the display mode may be automatically set by determining the size of the document using the function of the determining means 6.

Next, the function of the dividing means 7 of the display control means 2 will be explained. In normal scrolling, the display area continuously moves little by little, but as shown in FIG. The display area can be divided into sections and displayed separately when scrolling, allowing quick movement of the display area. Note that a portion of each adjacent section may be displayed in an overlapping manner.

〔Effect of the invention〕
