Abstract

PURPOSE: To eliminate the need of specifying dimensions every time of transmission by scanning an original and inputting images corresponding to original dimension information and adding white data in a main scanning direction based on the original dimension information by a white data addition means at the time of transmitting the images. CONSTITUTION: The images are read by a scanner and scanning is normally performed by an original size recognized by this image processor. Thereafter, the binary images of a specified size binarized in a core part 10 are sent to a facsimile part 4, encoded and tentatively stored in a hard disk 11 through an SCSI controller. Further, when a call is originated and an opposite machine is connected, tentatively encoded information is called from the hard disk 11, decoded and returned to image information. Thereafter, it is variably magnified and encoded and transmitted matching with the opposite machine. In the case of an undefined size, the white data are added here and normalization to a normalized value or reduction to the normalized value is performed.

Encoding is performed by the method and the encoded information is written in the B memory 406. Codec 41 for A4 size image information
When 1 is encoded, the CPU 412 connects the signal line 456 of the B memory 406 to the CPU bus 462 by controlling the memory controller 404. CPU4
12 sequentially reads the coded information from the B memory 406 and transfers it to the modem 414. The modem 414 modulates the encoded information and transmits the fax information on the telephone line 13 via the NCU 415.

Next, the fax reception operation will be described. The information sent from the telephone line 13 is input to the NCU 415, and is connected to the fax unit 4 by the NCU 415 according to a predetermined procedure. Information from NCU 415 enters modem 414 and is demodulated. The CPU 412 stores the information from the modem 414 in the C memory 407 via the CPU bus 462. When the information of one screen is stored in the C memory 407, the CP

The CPU 1003 communicates with the CPU 1003 of the core unit 10 via the CPU 10, and the setting for outputting an image from the D memory 408 through the core unit 10 to the printer unit 2 or the image memory unit 9 is performed. When the setting is completed, the CPU 412 activates the timing signal generation circuit 409, and the signal line 46

The operation from 0 to outputting to the printer 2 or the LAN interface unit 9 has been described in the core unit 10 described above, and thus the description thereof is omitted.

[Description of Custom Size Setting Operation] Next, the document size setting operation will be described with reference to FIGS. 6 and 7.

FIG. 6 shows an example of the document size setting screen on the display means provided on the operation unit 124 (see FIG. 3). When the document size cannot be selected automatically or when the document size is intentionally designated. In this case, this screen is opened. Normally, auto is selected (the color of the key 601 displayed as auto is different from the colors of the other keys), and when selecting the standard size, the original size is displayed in multiple A key corresponding to a desired size among the keys 602 to 609 is touched with a finger to select it. To specify a custom size, touch the key 610 displayed as free to select it. Further, the key 611 displayed as a user is a key for calling out the registered information among the free size-designated information.

FIG. 7 shows an example of a screen when Free is selected on the display means provided on the operation unit 124 (see FIG. 3). User is X (main scanning direction), Y
Specify the document size (in the sub-scanning direction) in mm. When the registration key 701 is touched with a finger after the original size is designated, the original size is registered. After that, the user simply calls a predetermined key on the screen of FIG. be able to. Here, the registration means the state stored in the memory 125 of FIG.

Next, the fax transmission operation will be described with reference to the flow of the image signal.

First, an image is read by a scanner. At this time, the document size is normally scanned by the document size recognized by the image processing apparatus. As described above, if the user manually specifies the document size, the scanner scans the image accordingly. Then, the binary image of the designated size binarized by the core unit 10 is sent to the fax unit 4, encoded, and temporarily stored in the hard disk 11 via the SCSI controller 413.

When a call is further made and the other device is connected, the coded information is once called from the hard disk 11, is decoded, and is returned to the image information. After that, the data is scaled and coded according to the partner's machine and transmitted, but in the case of an irregular size, white data is added here to be normalized to the standard value or reduced to the standard value. . It is not necessary to add white data in the sub-scanning direction.

It is possible to add white data for main scanning when the scanner scans an image,
If white data is added during scanning, it is treated as normalized data after that, and white data is also reduced, such as when it is reduced during transmission. This causes a problem that the white data is reduced more than necessary.

In the above embodiment, only the original size is registered. However, the present invention is not limited to this, and the communication mode information including the destination telephone number is registered. Good.

[0053]

As described in detail above, according to the image processing apparatus of the present invention, it is possible to transmit a document of an irregular size without waste, and the document size information storage means is provided, which is unique to the user. It is possible to improve the operability when transmitting a document of an irregular size.
