The stored image information is stored in the bit map memory 28b of the display information control unit 28 via the bus control unit 25, and is read from the bit map memory 28b and displayed.

Further, the adjacent two sides of the CRT display 30 and the adjacent two sides of the displayed first and second image information P ₁ and P ₂ respectively have, for example, enlargement, reduction, rotation of the displayed image information, A plurality of so-called icons Ic for selecting various editing functions such as reading out a designated area, combining, etc. are displayed, and displayed image information includes, for example, OR, AND,
Invert, ex (excursive) -icons Ic ₁ , Ic ₂ , Ic ₃ , Ic ₄ for executing logical operations such as OR, and an icon for overwriting to instruct display of image information Ic ₅ is displayed.

In the above display state, when the first image information P ₁ and the second image information P ₂ are edited, the second image is displayed after the first image information P ₁ is indicated by the mouse 16, for example. It indicates the first display center of the image information P ₁ in the information P _2, further and instructs an icon Ic ₅ showing the overwriting, the page buffer 29 in response to a command CPU 12, the first image information P ₁ is It is read and supplied to the display information control unit 28 via the bus control unit 25. This display information control unit
At 28, the first supplied via interface 28a
Is supplied to the arithmetic unit 28c, and the second image information P ₂ read from the bitmap memory 28b is supplied to the arithmetic unit 28c. Further, the designation signal Ip corresponding to the overwrite supplied from the CPU 12 is supplied to the calculation unit 28c via the display control unit 28e.
Accordingly, the computing unit 28c performs the overwrite computation corresponding to the superimposition of the first image information P ₁ and the second image information P ₂ . This calculation result is again stored in the bitmap memory 28b.
And is displayed on the CRT display 30 under the control of the display control unit 28e. Therefore, as shown in FIG. 3B, the second image information is displayed on the CRT display 30.
Image first image information P ₁ is superimposed is displayed on the P _1.

In addition, in the display state shown in FIG.
After the first image information P ₁ is designated by 16, the display center of the first image information P ₁ in the _second image information P ₂ is designated,
Further, when the icon Ic ₁ indicating OR is designated, the first image information P ₁ is read from the page buffer 29 and supplied to the display information control unit 28 via the bus control unit 25. In the display information control unit 28, the first image information supplied via the interface 28a is supplied to the calculation unit 28c as well as the bitmap memory 28b is supplied to the calculation unit 28c.
The read second image information P ₂ is supplied. Also,
A designation signal Ip corresponding to the OR supplied from the CPU 12 is supplied to the calculation unit 28c via the display control unit 28e, and in accordance with the designation signal Ip, the calculation unit 28c causes the first image information P
_An OR operation is performed corresponding to the superposition position of ₁ and the second image information P ₂ . This calculation result is again stored in the bitmap memory 28.
It is stored in b and is displayed on the CRT display 30 under the control of the display control unit 28e. Therefore, as shown in FIG. 3 (c), the CRT display 30 displays the second image information.
P ₂ is displayed in a state of being transparent to the first image information P ₁ . Therefore, since the second image information P ₂ of the portion where the first image information P ₁ is superimposed can also be viewed, the range of editing work is wide and the editing work can be performed efficiently. .

Further, in the state shown in FIG. 3 (c), after specifying the first image data P _1, it indicates the first display center of the image information P ₁ in the second image information P _2, further for example When the icon Ic ₅ indicating the overwrite is designated, the above-described operation is performed and the display state shown in FIG. 3B is obtained.

This is advantageous, for example, in the case of collating the first image information P ₁ and the second image information P ₂ which are similar images. As described above, if the AND icon Ic ₂ is designated after the first and second image information P ₁ and P ₂ are designated, the AND operation of the first and second image information P ₁ and P ₂ is performed. If the first and second image information P ₁ and P ₂ are the same image, as shown by P ₃ ,
The same image information as the first and second image information P ₁ and P ₂ is displayed.

FIG. 5 shows the operation when the icon Ic ₄ for instructing the ex-or operation is designated. This ex-or operation is advantageous, for example, when editing the first image information P ₁ consisting of a fine and complex image or a dark image and the second image information P ₂ consisting of a simple image. . In this case, if the ex-or icon Ic ₄ is designated after designating the first and second image information P ₁ and P ₂ as described above, the first and second image information P ₁ and P ₂ Ex-OR calculation is performed, and different parts of the first and second image information P ₁ and P ₂ are
As shown by P ₃ , the second image information P ₂ is displayed because it is displayed in white.
It is possible to make it easier to see.

Further, when the icon Ic ₃ is designated, the inversion calculation is performed. This inversion operation inverts the white level and the black level of the designated image information and superimposes it on other image information, which makes it easy to see the image information.

According to the above embodiment, the image information stored in the bit map memory 28b and the image information read from the page buffer 29 are supplied to the arithmetic unit 28c, and the specified logical operation is performed in this arithmetic unit 28c. It is displayed on the CRT display 30. Therefore, it is possible to set the display format of the image information to be superimposed and displayed according to the purpose of editing, which makes it easy to see the display and widens the editing work range. The processing can be performed efficiently.

The first and second image information is not limited to the image information read by the scanner 26, but may be, for example, character information input from the keyboard 15 or handwriting input information input from the tablet 18.

Of course, various modifications can be made without departing from the scope of the invention.
