Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image communication apparatus such as a facsimile apparatus and, more particularly, to a method of dividing or transmitting large-size high-resolution image data and transmitting or recording the data.
The present invention relates to an image communication apparatus that creates a thumbnail image by reducing each of the plurality of divided images and performs duplex printing.

[0002]

2. Description of the Related Art In recent years, digitalization has advanced in the field of copying machines, and many digital copying machines having a facsimile communication function have appeared.

Conventional copying machines include, for example, A1 reading, A
Some have a function of reading / recording a large size such as one record. The digitization of these large-sized copying machines is progressing, and the definition of the digital machines is also progressing. For example, high-definition copying machines of the 1200 DPI class are also appearing.

However, in the field of facsimile, desktop type office products and small home facsimile apparatuses are mainstream, and the recording paper size is A4 or B.
4 is the mainstream. Also, in order to shorten the transmission time, 3
Compared with the 00 DPI and 400 DPI copiers, the facsimile apparatus mainly has a low resolution.

On the other hand, ecology has been shouted out in the world, and facsimile apparatuses having a double-sided printing function for reducing paper consumption by half have been popularized in the world.

[0006]

If a communication function is provided in a conventional digital copying machine having a large size and a high resolution, the transmitting device can read the data at a large size and a high resolution. Many paper sizes are small and the resolution is poor, resulting in high magnification and reduced resolution at the sending or receiving end. Therefore, even if the transmitting side is provided with a large size / high resolution reading function, there is a problem that the large size / high resolution reading function cannot be utilized.

For example, even if an A1 size map is sent on the transmitting side, when it is received, it is reduced in size and the resolution is reduced. Therefore, this received map is used in the same manner as the A1 size map before transmission. I can't.

[0008] Further, when a poster including a life-size model is received, the size of the model is reduced, so that there is a disadvantage that the height of the model cannot be accurately grasped.

In order to solve the above-mentioned problem, it is conceivable that the transmission side or the reception side divides the original image in accordance with the recording paper size of the reception side from the viewpoint of emphasizing unity magnification. On the other hand, from the viewpoint of emphasizing high definition, it is conceivable to divide the original image on the transmitting side or the receiving side according to the number of print pixels on the receiving side. In this case, the receiving side user joins the divided and recorded images.

[0010] However, there is a problem that the joining operation is very complicated when the number of received and recorded images is large and the images are similar in the joining operation.

The above-mentioned problem is a problem that occurs also in image communication apparatuses other than facsimile apparatuses such as personal computers having an image communication function.

According to the present invention, there is provided an image communication apparatus in which, when an original image is divided and transmitted, the divided image data is received at a receiving side, and the recorded images are joined, the joining operation is easy. It is intended to do so.

[0013]

According to the present invention, there is provided an image dividing means for dividing read original image data into a plurality of image data, and an image data reducing means for reducing the plurality of divided image data. A reduced image data combining means for combining the plurality of reduced image data into one image data; and a mutual positional relationship between the reduced image data based on the original image before being divided. A positional relationship data calculating means for calculating positional relationship data indicating the above, transmitting the divided plurality of image data, the reduced and combined image data, and the positional relationship data to a partner machine. And an image communication device having a transmitting unit that performs the transmission.
