Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an image information processing apparatus that adds white information of the same length to both ends of input image information and outputs the resultant image information.

Conventional technology Traditionally, in facsimiles, etc., when the recording paper size on the receiving side is larger than the sending original size, white image information is added to both ends of the input image information so that the input image is recorded in the center of the recording paper. A Nishida image information processing device has been proposed.

A conventional image information processing device will be described below.

FIG. 4 is a schematic block diagram of a conventional image information processing device, in which 1 is an input section for A4 size image information a, 2 is an output section consisting of a shift register and outputs B4 size image information i, and 3 is an output section for outputting B4 size image information i. An image information control unit that controls the addition of white information, 4 a line memory that temporarily stores the input image information a, 5 a write address counter, 6 a read address counter, and 7 a white unit that is added to the image information a. Count information 1
A 60-bit white addition counter, 8 a counter for outputting image information, and 9 a shift register provided inside the output section 2.

Regarding the image information processing device configured as described above, the fifth
The following description will be made with reference to the timing diagram shown in the figure.

In order to add white information to the image information a input through the input section 1 and output it to the output section 2 as B4 size image information,
First, when image information a, in which one line corresponds to the horizontal length of A4 size paper, is input from the input section 1 to the image information control section 3,
The image information control section 3 generates a "write address counter control signal" at the same time as the start of data input, and the counting operation of the write address counter 5 is started. Then, the write address counter 5 outputs a write address signal k to the line memory 4 based on the counted value, and also outputs a write address signal k to the image information control section 3.
temporarily stores the image information a in the line memory 4 while performing line management of the image information a based on the write address signal k.

Next, in order for the image information control section 3 to output image information of B4 size horizontal length to the output section 2 from the image information a for one line, first, white information to be added to the image information a is added to the image information a. The counting counter 7 is operated, and at the same time, the output data enable signal is changed from the H level to the L level, and is output to the shift register 9.

Incidentally, at this time, the shift clock C to the shift register 9 is always outputted from the image information control section 3.

Furthermore, when the counter 7 overcounts, the information is input to the image information control section 3 as a count signal e. At the same time, the counter 8 for outputting A4 size data is outputted to the read address counter 6 as a read address count signal e.

The image information control section 3 sends a read address signal according to the count value of the read address counter 6! Based on this, the previously stored image information a is retrieved from the line memory 4 and outputted following the white information.

When the A4 size image information a is output, the counter 8 counts over and generates a signal f, which is input to the image information control section 3 and the counter 7.

Then, image information i is formed in which 160-bit white image information g is added to both ends of the image information output from the image information control unit 3 corresponding to image information a, and this image information 1 is Shift register 24 inside output section 2 along with C
sent to. In this case, the length of one line of image information is
The total length is B4 size.

As mentioned above, in the conventional image information processing device, for example, A4
B4 size image information was generated by adding 160-bit white image information to both ends of the size image information.

Problems to be Solved by the Invention However, in the conventional configuration described above, there are a large number of counters used when outputting the image information with white image information added to both ends of the image information. Since information is added, there are problems in that the device becomes complicated and the operation of each counter becomes complicated.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned conventional problems, and an object of the present invention is to provide an image information processing device that has a simple configuration and can add white information to image information.

Means for Solving the Problems To achieve this object, the image information processing apparatus of the present invention comprises:
The output section is equipped with a shift register with a larger number of bits per line than the input section, this shift register is filled with white image information in advance, and the image information with the white image information added only to the rear end is shifted. It is configured to output to a register.

Effect With this configuration, when adding white image information to the image information input at the input section using a facsimile or the like and outputting the image information to recording paper of a different size, the image information input at the input section is By simply adding white image information to only the edges, the output section can output image information with white image information added to both ends.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic block diagram of an image information processing apparatus in an embodiment of the present invention. In FIG. 1, 1 is an input section, 2 is an output section, 3 is an image information control section, 4 is a line memory, 5 is a write address counter, 6 is a read address counter, and 9 is a shift register. It is the same as the configuration. 10 is A4 size image information a
1728-bit counter that counts 11 is 16
This is a counter that counts 0-bit white image information.

The operation of the image information processing apparatus of this embodiment configured as described above will be described below with reference to the timing diagram of FIG. 2 and the explanatory diagram of FIG. 3.

First, the image information control section 3 clears the shift register 9 in the output section 2 in advance before transmitting the image information.

Next, A4 size image information a' is written from the input section 1 to the line memory 4. In other words, this image information a' is 1
A4 size line (1728 bits) is output from the image information control unit 3 to the write address counter 5 to start counting, and according to the count value of the write address counter 5 is input from the input unit 1. The image information a' of is temporarily stored in the line memory 4.

Then, in order to output the image information a' written in the line memory 4 to the shift register 9 in the output section 2, first,
At the same time as the output data enable signal S is changed from H to L, the read address counter 6 and the counter 10 are activated by the count start signal d. When the output of A4 size image information is finished, the counter 10 counts up and generates a signal r', and the 160-bit counter 11
and is input to the image information control section 3. When the signal f is input to the image information control section 3, the output image information is changed to white image information and 160 bits of white information are added. Furthermore, when the counter 11 counts up, the output data enable signal is
to H to complete the transfer of one line.

Note that the shift clock C is constantly outputted from the image information control section 3 to the shift register 9.

That is, as shown in FIG. 3, the shift register 9 of the output section 2 is cleared at the time of the first initial setting, so
As shown in Figure M, it is filled with white information. If the A4 size image information a' is shifted here, it becomes n.

Then, when 160 bits of white image information is added to the rear end of the image information, 160 bits of white image information are added to both ends of the A4 size image information, such as 0, resulting in B4 size image information.

Furthermore, if 160-bit white image information is added to the rear end of the A4 size image information, the next line of A4 size image information changes in the order of p-+q-+r as shown in Figure 3, and the B4 size image changes. Information can be generated.

Although the above embodiment describes reproduction of image information from A4 size to B4 size, the present invention is not limited to this.

Effects of the Invention The present invention adds white image information only to the rear end of the image information for each line, connects this to an output section in which white image information is set in advance, and sequentially connects it to the image information of the previous line. This makes it possible to output image information on recording paper of different sizes in facsimiles, etc., and in particular in facsimiles, it is extremely easy to always receive documents with a constant document width on the receiving side, regardless of the document width on the sending side. This has the effect that it is possible to
