Abstract

PURPOSE:To reproduce an image at the same magnification as that of its original image on a receiving side when the linear density on a transmitting side is different from that on the receiving side, by deciding the conversion efficiency of resolution by receiving the resolution of the original document on the transmitting side and converting the resolution of image information in accordance with the conversion efficiency. CONSTITUTION:On a transmitting side, a transmitting document is inputted by means of a document inputting means A and an image information implementing means B encodes the document and produces image information. A resolution transmitting means E transmits the resolution calculated by an original resolution generating means C from inputted data and an image information transmitting means D transmits the image information. On a receiving side, on the other hand, a resolution receiving means G receives the resolution calculated on the transmitting side and a conversion ratio deciding means I calculates a thinning ratio from the resolution and informs an image information resolution converting means H of the calculated thinning ratio. The received image information is outputted to a printer, etc., by means of a received information outputting means J after the resolution of the image information is converted with the thinning ratio decided by the means I and a copy of the image information of the same magnification as that of the original image information is outputted. Therefore, an image can be reproduced at the same magnification as that of the original image.

Next, the actual communication procedure will be explained with reference to FIG.

First, the transmitting side sends a calling signal (CNG), and when the called side receives the calling signal (CNG), it sends a cold signal (CHD), and then the called terminal sends a CC
ITT standard digital identification signal (DIS) indicating receiving function
) to send. The DIS signal informs the calling terminal of all the capabilities of the called terminal on the called side. Next, the non-standard function identification signal (N
SF-dpi). The calling terminal sends a digital command signal (DC3) and a non-standard function command signal (N
SC-dpi). This signal is a digital command that responds to the information contained in the NSF signal.

Then, a training check (TCP) is sent to check the training of the modem for receiving facsimile messages, and to check whether the channel can be used at this transmission speed.

In response, a message confirmation signal (MCF) is sent from the called terminal.
indicates that the message has been completely received.

This causes the calling terminal to transfer data to the called terminal.

FIG. 10 is a blinding parameter table.

In the figure, FF F F F H in the part marked "*1j" is not subjected to the dipping process. The part marked "*2" is
×The ratio of 1 book to every book is dazzling. The part marked with "*3" is increased by one per X X H of 0IXXH. Also, when the data is dizzy, the previous data and the data that is dizzy are ORed. Also, when increasing, increase the same data as the previous data.

FIG. 11 shows a deflection rate calculation means, which determines the table shown in FIG. 10 from the printer resolution on the receiving side, and obtains the deflection rate from the transmitting side dpi code. For example, if the resolution on the receiving side is 180 dpi, the resolution on the sending side is also 180 dpi.
dpj, the dpi code is ○IH and the blinding rate parameter is FFFFFH, so no blinding is performed. Also, the resolution on the transmitting side is dip mill code 3H (24
If the receiving side is 0 dpi) and the receiving side is 80 dpi, the blinding rate parameter is OOO4H, which means that one out of every four videos will be dazzled.

Furthermore, the printer on the receiving side is 240 dpi and the printer on the sending side is 18 dpi.
0clp], the deflection rate parameter is 0103, and on the contrary, it is increased at a rate of one in three.

In this way, processing that could not be done with conventional procedures can be done by =12
- The sending side sends the resolution information of the document or image, and the receiving side can enlarge or reduce the document or image based on that information and output a copy at the same size as the original document.

Effects As explained above, according to the present invention, even if the linear density on the transmitting side and the linear density on the receiving side are different, it is possible to reproduce an image at the same size as the original image.
