JP2001169074A - Image forming device and storage medium storing program - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an image forming device where it can easily be recognized whether an image which is facsimile-received and outputted is an exact copy or not on a reception side and to provide a storage medium storing a program. SOLUTION: The image forming device has CPU 1, ROM 2, RAM 3, a control panel 4, a color printer 5, MODEM 6 and NCU 7. The image received through NCU 7 and MODEM 6 is judged in such a way whether it needs to be reduced by CPU 1 or not. When it is reduced, the reduced image is outputted as a color image in an arbitrary color by using the color printer 5. Thus, a user can easily learn that the received image is obtained by reducing the original image since the outputted image is the colored one.

And the modem 6 are connected via a BUS (bus),
The modem 6 is connected to a telephone line via an NCU (Network Control Unit) 7.

The CPU 1 controls reading by a scanner or the like (not shown), writing of the read data or received data, and operation of the entire image forming apparatus, based on a control program stored in a ROM 2 described later. Data sets and fetches of necessary addresses are performed via a BUS (bus) connected to each peripheral portion.

The ROM 2 is a memory area in which a control program for controlling the operation of the entire image forming apparatus is stored.

The RAM 3 has a work memory area for control.
This is a page memory area.

The operation panel 4 is an operation unit composed of a liquid crystal touch panel, etc., and is a display function for inputting various settings and operation instructions of the image forming apparatus and displaying an operation state or an abnormal state of the image forming apparatus. Also have.

The color printer 5 performs color printing of images and characters of facsimile-received data and data to be color-copied.

The modem 6 is a modem that converts a signal received via a telephone line from an analog signal to a digital signal, and converts a signal to be transmitted to the telephone line from a digital signal to an analog signal.

An NCU (network control unit) 7 controls connection such as outgoing call, incoming call, restoration, disconnection, etc., when using a communication device having no network control function in a public network such as a telephone line. I do.

In the case of facsimile, transmission and reception by the modem 6 are performed through the NCU 7. In the case of a color MFP multifunction peripheral having a facsimile function, the multifunction peripheral includes all of a color printer 5, a modem 6, and an NCU 7.

The image signal demodulated by the modem 6 is once R
Stored in AM3. If the CPU 1 determines that the image signal is different from the original document image by reducing the image signal, the reduced image is printed as a color image in an arbitrary color by the color printer 5 under the control of the CPU 1. Out. Therefore, the user can know that the reduction processing has been executed in the image forming apparatus by outputting the color image.

Next, specific embodiments of the present invention will be described below.

<First Specific Example> As a first specific example of the present invention, it is assumed that, for example, a document is sent in a B4 width from the transmitting side, but only a sheet of A4 width is set on the receiving side. At this time, the output is controlled so that the received B4 data is reduced to A4 width data so that all the data enters the A4 width. The same applies to the case where the width is reduced from A3 width to B4 width and from A3 width to A4 width.

Conventionally, it was difficult to determine whether or not an image printed out was original data because the image was drawn in monochrome (black and white). By setting the color and outputting the color, the user can easily recognize that the reduction processing has been performed.

<Second Specific Example> As a second specific example of the present invention, for example, it is assumed that the receiving side has received by two-dimensional compression. FIG. 2 shows a configuration of received data configured by two-dimensional compression.

In FIG. 2, EOL (End of Line) is a signal indicating the end of a line. Thereafter, the data is read, and EOL + 1 represents one-dimensional compression, and EOL + 0 represents two-dimensional compression. Here, the number of bits is determined by the size of the paper, and if the demodulated data is different from the specified number of bits (overflow if large, underflow if small), an error is generated by replacing with the previous correct line. Correction has been performed. In that case,
In the present embodiment, the line has been replaced with black and white, but in the present embodiment, the error corrected line can be replaced with color to recognize the error line.

<Third Specific Example> As a third specific example of the present invention, for example, it is assumed that the receiving side has received by two-dimensional compression. FIG. 3 shows a configuration of received data configured by one-dimensional compression.

The basic configuration is the same as that shown in the second embodiment. When an error is detected in a line received by the primary compression method, the line is replaced with the previous line. Output.

Incidentally, the ROM 2 in FIG. 1 constitutes a storage medium according to the present invention. This storage medium contains
A program for executing the operation in the above-described embodiment of the present invention is stored.

As the storage medium, a semiconductor storage device, an optical disk, a magneto-optical disk, a magnetic recording medium, or the like can be used.

A color MFP machine equipped with a facsimile function, which is a digital color multifunction machine, can perform color print output. In the present embodiment, by utilizing this point, if any processing such as reduction processing and error correction is performed on an image received even in monochrome data transmission, printing is performed in color, so that the user can process the processed image. So that it can be recognized.

[0038]

As is apparent from the above description, according to the first and sixth aspects of the present invention, when the output image on the receiving side is different from the original image from the transmitting side, a composite having a color printer function is provided. By taking advantage of the fact that the part is used and outputting that part in color, it is possible for the receiving side to immediately determine where the difference is, so that the receiving side user can easily determine whether accurate information is being sent.

According to the second and seventh aspects of the present invention, when the received image is reduced, the reduced image is output in color, so that the receiving user can recognize that the size of the original is different from that of the original. Can be easily determined.

According to the third, fourth, fifth, eighth, ninth and tenth aspects of the present invention, an error occurs when reading is performed on the receiving side, and error correction is performed to replace the previous line. By performing color output in the case where is performed, it is possible to easily recognize the location where the error has occurred. Therefore, since the location where the character or the like is difficult to read can be immediately identified, it is possible to ask the transmission side to retransmit the information, or the receiving side can inquire the sender about the information of the location where the error has occurred.
