Abstract

PURPOSE:To allow the operator at the reception side to recognize information relating to variable magnification executed at transmission/reception while having only to observe a recording picture by sending the information relating to the variable magnification processing together with a magnified original picture as picture information. CONSTITUTION:A read section 1 consisting of a CCD line sensor uses a control section 3, which controls to read and original picture one prescribed scanning line each and sends the result to a reduction section 2 as white/black binary dot data. The reduction section 2 interleaves the dot data of inputted picture to reduce the picture at a prescribed ratio and outputs the result to the control section 3. The outputted picture data is sent to a telephone line or the like via a MODEM 4 sequentially from the control section 3. Further, the control section 3 calls the dot data relating to the ratio of reduction from a character generator 5 and adds it to a prescribed location of the original picture as the picture information and sends the result. The operator at the reception side can recognize the change in the magnification by the added data.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine, and particularly to a facsimile machine that performs scaling processing to reduce or enlarge a document image and transmits the image to a receiving side.

[Prior Art] Facsimile machines have been known that reduce or enlarge a document image at a predetermined ratio and transmit the image to a receiving side. In particular, image reduction may be performed according to the operator's specifications, but in most cases it is automatically selected depending on conditions related to the recording capacity of the receiving side, such as the recording paper on the receiving side being smaller than the original image on the sending side. It is often done.

[Problems to be Solved by the Invention] Therefore, the operator on the receiving side cannot determine whether the received image is the same size as the original or whether it has been reduced. Especially when the received image consists of small characters that cannot be deciphered, it is not possible to know the magnification at the time of sending and receiving the original, so even if the sending side sends it again, a decipherable received image can be obtained. There was a problem in that it was not possible to immediately determine whether

[Means for Solving the Problems] In order to solve the above problems, the present invention performs scaling processing to enlarge or reduce the original image at a predetermined magnification,
In a facsimile device that transmits a scaled image to a receiving side, when carrying out the scaled transmission described above, a configuration is adopted in which information regarding scaling processing is transmitted as image information together with the scaled original image.

[Operation] According to the above configuration, the operator on the receiving side can read the recorded image,
Just by looking at it, you can know information about the change in magnification that was made during transmission and reception.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 is a block diagram showing an embodiment of a facsimile device adopting the present invention. Here, only the constituent members of the facsimile device necessary for reducing and transmitting a scanned original image are shown. Other components are not shown in Figure 0. In Figure 0, reference numeral 1 denotes an image reading section composed of a CCD line sensor, etc., and this reading section 1 is controlled by a control section 3 composed of a microcomputer, etc. to image an image of a document. is read one predetermined scanning line at a time and outputted to the reduction unit 2 as binary dot data of white and black.

The reduction unit 2 reduces the original image at a predetermined ratio by a known method such as thinning out the dot data of the image output from the reading unit 1, and outputs the reduced image to the control unit 3. The output image data is sequentially transmitted by the control unit 3 to a predetermined line such as a telephone line via the modem 4. Further, a character generator 5 is connected to the control unit 3 in order to transmit communication date and time, a caller's telephone number, a name, and other sender information as image data.

Although the method for sequentially processing 1947 worth of image data has been described above, a configuration may also be used in which the image data is stored in the memory before or after reduction.

FIG. 2 is a flowchart showing a control procedure when reducing and transmitting an image performed by the control section 3 in the configuration shown in FIG. The procedure shown in Fig. 2 is stored in the ROM as a program for the control unit 3.
The information shall be prepared in advance in a storage medium such as

In step S1 of FIG. 2, it is determined whether or not to reduce the original image and transmit it based on a communication procedure or a predetermined operation. If reduced transmission is to be performed, the process advances to step S2; otherwise, the process directly advances to step S3.

In step S2, dot data regarding the reduction of the original image to be performed from now on is called from the character generator 5 based on the reduction ratio, and this image information is added to a predetermined position of the original image, for example, at the beginning.

Subsequently, in step S3, the character generator 5 transmits control information mainly related to the originating station, such as date and time of communication, telephone number, name, or page number of the originating station, as image data.

Subsequently, in step S4, the original image read by the reading section 1 is transmitted, but if reduced transmission is selected in step s1, the document image is reduced by a predetermined ratio in the reducing section 2 and transmitted to the receiving side.

FIGS. 3 and 4 show the recording state of the image data transmitted through the above processing on the receiving side.

If reduced transmission is not performed, step s2 is omitted, so the first part of the original image recorded on the receiving side is the third
It will look like the figure. In the example shown in FIG. 3, the communication date and time and page number are recorded as sender information A at the beginning of the document.

Further, in the case of reduced transmission, the process of step S2 is performed, so the leading portion of the recording paper recorded on the receiving side becomes as shown in FIG. As shown in FIG. 4, in this case, information B regarding the presence or absence of reduction and the reduction ratio, which is called and transmitted from the character generator 5 in the process of step S2, is recorded. Here, in terms of magnification, it is shown that a B4 size document is reduced to an A4 size image. However, the display of the magnification does not have to be based on the document size as described above, and the reduction magnification may be directly recorded numerically, such as <1, for example, r O, 75 times."

In the embodiments described above, an example was shown in which the original image is reduced and transmitted, but the scaling process is not limited to reduction, and the same technique as described above can be applied to the case where the original image is enlarged.

With the above configuration, the operator on the receiving side can be informed of what kind of scaling processing has been applied to the original image based on the image information, and the operator on the receiving side can print the recorded image using a copying machine or the like after receiving it. The original image can be easily restored by changing the magnification.

For example, even if a document is reduced to an undecipherable size when a reduced transmission is performed, it is possible to quickly and reliably create a decipherable document image by notifying the sender of appropriate scaling conditions and having the sender perform the transmission again. can be obtained.

Furthermore, since the scaling conditions for the image information are recorded on the recording paper on the receiving side, the usage status of the document width on the sending side can be accurately grasped.For example, in a receiving device that can use recording paper of multiple sizes, It becomes possible to very easily determine the size of the recording paper according to the width of the document on the sending side.

[Effects] As is clear from the above description, according to the present invention, scaling processing is performed to enlarge or reduce the original image at a predetermined magnification,
In a facsimile machine that transmits a scaled image to the receiving side, when carrying out the scaled transmission described above, a configuration is adopted in which information regarding the scaling process is sent as image information together with the scaled original image, so that the receiving side This has an excellent effect in that the operator can be informed of information regarding the image magnification conditions, and the receiving operator can utilize this information to effectively use the functions of the receiving device.
