Description

Description: TECHNICAL FIELD The present invention relates to an image processing method for arranging and transmitting a plurality of document images.

<Prior Art> Conventionally, for example, as shown in FIG. 2, when a plurality of A5 size originals OG are transmitted and the receiving side has a recording paper roll PP having an A3 longitudinal width, an image is displayed only on a broken line portion on the recording paper PP. Is recorded.

Therefore, there are drawbacks that about half of the recording paper is wasted, and that the communication time is increased because the procedure signal is exchanged for each document.

<Means for Solving the Problems> In view of the above points, the present invention provides a step of reading a plurality of document images, a step of determining a recording paper size of a receiving-side communication device, Arranging a plurality of read manuscript images in a main scanning direction on a memory according to the manuscript size, and indicating a page number of the manuscript on each of the plurality of manuscript images arranged on the memory in the arranging step; Adding a character, notifying the communication device on the receiving side of the size of the image to be transmitted arranged on the memory, and a plurality of document images arranged on the memory and added with page numbers And transmitting the image data.

<Embodiment> FIG. 3 is a control circuit diagram of the facsimile apparatus of this embodiment.

In the figure, 10 is a reader for reading an original, 12 is a printer for recording a received image or a copied image, 14 is a CPU for controlling the entire facsimile apparatus, 16 is a ROM storing a control program for the CPU 14, and 18 is necessary for controlling the CPU 14. RAM for storing various data, for example, the count value of a counter, the state of a flag, etc., and image data, and a coder / code 20 for encoding and decoding an image signal.
Decoder, 22 is a modem that modulates and demodulates image and control signals, 24 is an NCU that switches between connecting communication line 28 to telephone 26 or modem 22, 30 is a sensor for detecting document size, and 32 is a record This is a sensor for detecting the paper size.

FIG. 4 is a control flow chart of the present embodiment, in which a program is stored in the ROM 16.

In S101, it is determined whether or not the other party can receive A3 (this is performed by analyzing the DIS signal indicating the function of the other party by the CPU 14), and S1
In 02, it is determined whether or not the document size on the transmitting side is A5. The CPU 14 inputs a signal input from the document size sensor 30 and checks the signal. In such a case, the CPU 14 arranges the image information in the RAM 18 in accordance with the program in the ROM 16 to perform the memory operation for converting the A5 original as shown in FIG. And DC to send in A3 size
Set the S signal, perform the procedure, and perform A3 size communication.

At this time, page information is added to each document and arranged in the memory (S105).

If not, the A5 size originals are transmitted one by one in A4 size (with "white" at both ends).

This is because CCITT uses A4 size as standard and there is no procedure for A5 size. B4 and A3 sizes are CCITT
Since it is specified as OPTION, it can be sent / received.

Since the minimum transmission time is specified in the main scanning direction, A5
If two sheets are sent, it takes about twice as long in image transmission time. Further, since a control procedure signal is exchanged between images, the communication time is further increased.

On the other hand, in the present embodiment, since two images can be transmitted as one image, the length in the sub-scanning direction (which greatly affects the transmission time) can be reduced to half, and the procedure signal between image signals can be omitted. And the communication time is shortened.

In the present embodiment, an example in which conversion is performed on the transmission side has been described. However, in order to prevent consumption of recording paper, conversion may be performed on the reception side, and page information may be added corresponding to each document.

The present invention is not limited to the case of A5 to A3, and the present invention can be implemented when the size of the read original is 1/2 or less of the recording paper.

<Effects> As described above, according to the present invention, in the communication device on the transmitting side, the recording paper size of the communication device on the receiving side is determined, and a plurality of document images are formed in accordance with the recording paper size and the document size. Characters indicating the page numbers of the originals are added corresponding to the respective original images, and the size of the arranged images is notified to the receiving communication device to be transmitted. Since the original image is transmitted in an arrangement corresponding to the size of the recording paper on the receiving side, the effect of reducing unnecessary waste of the recording paper on the receiving side and shortening the communication time is obtained. The effect of not requiring special improvement of the communication device on the receiving side by notifying the size of the document and the effect of being able to recognize the page on the receiving side by adding a page number to the arranged original image to be transmitted are obtained. La It is.
