This is a numeric keypad including a. 92 is a function key. The function keys 92 include a generation/modification key 92a, a transmission key 92b, and a reception key 92C for switching modes.

FIG. 3 is a block diagram of the image creating device. CPU
Please write images etc. in I.1. a RAM2. ROM 3 containing programs etc. A transmission control unit 41 that controls transmission and reception of images is connected to an interface 5 of peripheral equipment. A modem 6 is connected to the transmission control section 4, and this modem 6 is connected to a telephone line via a switch 7.

A telephone 8 is connected to the switch 7, and after setting up a telephone line with another image forming apparatus using the telephone 8, the switch 7 switches this line to the main body of the image forming apparatus. Also, the telephone 8 performs voice communication. The interface 5 includes the keyboard 9 and printer 10.
．． CRTI 1. Light pen 12, mouse 13. A Fronbi disk 14 is connected.

The operation of the above embodiment will be explained below with reference to the flowchart of FIG. After the image creation device is connected to another image creation device via a telephone line, when the mode setting key is pressed in step nl (hereinafter, step ni is simply referred to as ni), the mode setting key is pressed in n2 and n3. Determine which mode key was selected. If the pressed key is the generation/modification key 92a, the process advances to n4, and if the pressed key is the receive key 92b, the process advances to nl. If any other key is pressed, it is assumed that there is a setting error and the process returns to nl, instructing to redo the input. Using the telephone 8, decide in advance which side will be the sending side, and the sending side operates the generation/modification key 92a, and the receiving side operates the receive key 92b.
operate. On the sending side, press keyboard 9 with n4. Light pen 12. Generate or modify an image using the mouse 13 or the like (see FIG. 5), and wait until the transmission mode is set at n5. When the transmission mode key 92b is pressed to set the transmission mode, the image is transmitted to the destination image forming apparatus at n6, and when the transmission is completed, the reception mode is automatically set at nl. In this case, since the other party is set to receive mode, the received image is displayed on the CRTII. The image transmitted in n6 is corrected by the destination (receiving side) image creation device, and the corrected image is sent back again.

Wait at n8 until the reception is complete, and when the reception is complete, proceed to n9 and display the received image on the (1'?T screen 11. If this image is OK without modification, The confirmation key 91a is pressed by the user.If it is determined in nlO that the confirmation key 91a has been pressed, the image is stored in the floppy disk 14 with nil, an OK message is sent to the other party's image creation device, etc. It will stop after completing the termination process.

If the confirmation key 91a is not pressed but the generation/correction key 92a is pressed, the image still has corrections, so the process returns to n4 and the subsequent operations are repeated.

In the above flowchart, n4 corresponds to the image generation/correction means of the present invention, n6 corresponds to the transmission means, nl, n5 . n7 and keys 92a, 92b, 92c are mode switching means, n
9 and CRTll correspond to display means, and nlO and n12 correspond to determination means, respectively.

FIG. 4 is a diagram showing an example of a process in which an image is corrected by the above operation. Among the lines on the screen shown in this figure, the image shown in solid lines is the initially generated or received image, and the dashed line is the part of the image that has been additionally modified.The dotted line is the part of the image that has been deleted and modified. It is.

If you use the two-way image transmission dialogue system with the above configuration,
Since users in remote locations can create a single image in an interactive manner, it is possible to examine the image in a much shorter time than when the image is sent as a document by post. , and can be easily modified. Further, in this embodiment, after transmission, the receiver automatically switches to the receiving mode, and when the image has been transferred to the other party, it is no longer possible to modify the image. Therefore, simultaneous setting of the image generation/correction mode, which allows image correction to be performed on both sides at the same time, is prevented, and troubles can be prevented from occurring.

(Effects of the f1 invention) According to this invention, a transmission device is added to the image creation device, the created image is transmitted to the other party's image creation device, and the image creation device makes corrections and restores the original image. Since it is possible to modify one image interactively, when both parties are satisfied with the modification, the modification can be completed and the image can be saved by both parties. When a group of people consider creating an image, it is possible to create the image in a much shorter time than when leaving a legacy by mail, etc., and with close communication of intentions.
