Abstract

PURPOSE:To superpose the additional information on an original picture without missing the information on the original picture, by inverting the white and black of the picture information based on the white and black of the additional information to be superposed on the picture information which is transmitted and received. CONSTITUTION:A facsimile signal transmitter 1 includes a picture reading mechanism 2 and an additional information memory 3 which stores the additional information to be superposed on the picture information. The mechanism 2 and the memory 3 transmit the information to the signal lines (a) and (b) under the control of a transmission control part 4. An exclusive OR circuit 5 inverts ''1'' and ''0'' of the signal at a terminal (a) and delivers them to an output terminal (c) only when the input of a terminal (b) is ''1''. The output of the terminal (c) is modulated by a MODEM6 and fed to a communication circuit 7. Thus the additional information added at a white place is recorded as it is. In case the additional information is added at a place where white and black are mixed, the information is recorded with inversion carried out between the white and black.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile device and a facsimile device that transmits and receives information such as two documents, two graphics, etc. in black and white binary format.

Conventionally, in such facsimile apparatuses, it has been considered to combine some additional information from the Noaxmi 9 apparatus side with images to be transmitted or received, and to perform image synthesis by transmitting and receiving the images. Conventional image compositing methods have considered converting the information of the original image as much as possible, such as overlapping a part of the original image (additional information without changing it at all), or changing the original image when sending and receiving it. Methods are being considered, such as sending and receiving information that should be added beforehand or afterwards.

However, with these conventional methods, when the original image information and additional information are superimposed, C is inevitable (the two pieces of information overlap and become undecipherable, or when the information is sent and received without superimposing C)
Second, there were inconveniences such as the size of the paper at the time of reception did not match the size of the paper on the sending side. Furthermore, both of the f2 methods have the disadvantage that if the location of the original image and the additional information are the same, the additional information becomes completely undecipherable.

Therefore, the present invention solves these conventional drawbacks, and provides a facsimile device that can superimpose additional information on the original image without losing the information on the original image (in addition, it is possible to superimpose additional information on the original image using the paper size of the original image). The purpose is to

According to the present invention C2, in order to achieve this object, a configuration is adopted in which the image information transmitted and received (double balance) and the black and white of the additional information (2) are inverted, so the black and white of the image information transmitted and received is inverted. In this case, C2 is also used to invert the black and white of the additional information according to the black and white of the transmitted and received image information.

The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 shows an embodiment of a facsimile device based on the present invention C2, and a facsimile transmitter 1 (encircled by a dotted line) reads an image of an original such as a manuscript for each scanning line and transmits information on rob and rlJ. (Image reading mechanism 2 that converts the image information into two and sends the image information to the signal line a, and the image information (additional information to be doubled is converted into rOJ, rl according to black and white)
An additional information memory 3 storing logical information of J is provided. The image reading mechanism 2 and the additional information memory 3 sequentially transmit information to the signal lines a and bl from the control (3) C2 of the transmission control section 4. The signal lines a and b are connected to the dual power IX of the exclusive OR 5, and the output line thereof is connected to the modem 6C which is controlled by the transmission control section 4. The transmission data modulated by the modem 6c2 is transmitted to and received by the facsimile receiver 8ζ2 via the communication line 7.

The receiver 8C2 is provided with a modem 11 for demodulating the received take, and under the control of the reception control section 13, the modem 11 generates post-modulated data on the output line a'L2. Further, the C2 reception control unit 13 is connected to the additional information memory 12c2 storing information to be added.
The data appearing on output line 1)' from modem Wawa or ←0 pregnancy is input to exclusive OR 10 along with the data from Senshoben #11, and its output is recorded via output line C'. The information is input to section 9.

In such a configuration C2, when a command to read the image and start transmission is sent from the outside by the transmission control section 4C of the facsimile transmitter 1, the transmission control section 4 controls the image reading mechanism 2. The original is read line by line (4) at a time.As the original is read, the additional information on the sender side that has been pre-registered is read out from the additional information memory 3 on the sender side.At this time, the information to be added is Binary information is stored in the form of rob and rlJ (assuming that the binary information read from the image reading mechanism 2 and the additional information read from the transmitting side additional information memory 3 have exclusive logic). The C terminal and the b terminal C of the sum 5 are input. At this time, from the function f2 of the exclusive OR 5, as shown in Table 1 [2], the output terminal C (2 is the input of the b terminal
Terminal signals rlJ and rOJ only when “1”
is inverted, and when the input to the terminal is 10'' (2), the signal at the C terminal is output as is.

The output of this C terminal is modulated as it is by the modeno 6 and sent out to the communication line 7 (2).The thus sent data passes through the communication line 7 and reaches the facsimile receiver 8C2. is demodulated by the modem 11 and input to the a' terminal C of the exclusive OR 10.

On the other hand, when the take starts to be received, the modem 11 notifies the reception control unit 13 of a reception start signal. Upon receiving this, the reception control unit 13 reads out the reception side additional information registered in advance from the reception data input C1 and the reception side additional information memory 12 in synchronization with the reception data for each scanning line. Take is the b' terminal of exclusive OR 10 (
Both of us are strong. The output C' terminal f2 of the exclusive OR 10 is '' in Table 1, b/'s [17 state C1 of rOJ.Therefore, only when the input to the b' terminal is 11', the signal at the a' terminal rlJ, When "o" is inverted and 1) the input to the ' terminal is [0], the signal at the a' terminal is output as is. The output of this C' terminal becomes the Kugata signal of the recording section 9,
An image is output from the recording command C2 of the reception control section 13.

An example of combining images and additional information actually transmitted and received by such a facsimile device (2) is shown in Figures 2 and 3, and each figure (14.16 additional information on the sending side
Further, 15.17 is additional information on the receiving side, and it can be seen that these pieces of detailed information are combined with the original picture information 18.19+2. The location where additional information 14.15 is subdivided is the second
In the case of a white background as shown in the figure, the additional information is not reversed and is recorded as is, and in the case of a place where a white background and a black background coexist as shown in Figure 3 (if two pieces of information are added, the additional information is different from the background) It is recorded in color (that is, black and white is reversed) to prevent additional information from being lost.

Note that the relationship between the additional information and the image information of the original is a relative one, and even if the black and white C1 of the additional information is therefore inverted, the black and white of the image information is also reversed. It goes without saying that the same effect can be obtained even if

As explained above, according to the present invention (2), image information to be sent and received (black and white C1 of additional information to be double-combined, or black and white C1 of image information, and thus image information or addition (7)) is inverted. 1) It is possible to add additional information to the original image without increasing the size of the received image.

2) It is possible to add additional information regardless of whether the original image is black and white.

3) Among the actual facsimile manuscripts, the lack of original information in response to adding additional information (2) can be solved by choosing the line width and size of the additional information appropriately (2).
It can be prevented to a certain degree. If black and white inversion using additional information is not performed, if the width of the subdivided characters is set wider than the character width of the original image (2), the information of the original image will be completely lost, but
When reversing black and white, the wider the width, the more information can be prevented from being lost.

If the additional information completely overlaps with the information of the original picture, complete loss of the original picture information occurs only in C:, but this probability is extremely low.

Excellent effects can be obtained.
