Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine having a smoothing processing function.

[Prior Art] Conventionally, in this type of facsimile machine, it has not been possible for the transmitting side to control the operation of the smoothing processing function performed by the receiving side.

[Problems to be Solved by the Present Invention] In the conventional example described above, smoothing processing using a smoothing function is performed uniformly on the receiving side regardless of the type of image, so it is possible to apply smoothing processing to images that do not require smoothing processing, such as halftone images. There is a drawback that image deterioration occurs due to processing.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above-mentioned problems, and includes the following configuration as one means for solving the above-mentioned problems.

That is, an instruction means for instructing implementation or non-execution of smoothing processing on the reception side, a transmission means for transmitting an instruction from the instruction means to the reception side as a pre-transmission procedure, and an instruction for receiving an instruction from the transmission means at the time of reception. and control means for controlling the smoothing processing function.

[Operation] In the above configuration, execution or non-execution of the smoothing processing function on the receiving side can be controlled from the transmitting side, and processing can be stopped for images that do not require smoothing processing.

[Embodiment] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of the transmitting side of a facsimile apparatus according to an embodiment of the present invention, and FIG. 2 is a block diagram of the receiving side.

In FIG. 1, 1 is a document reading section that reads a document and generates image data, 2 is an image signal processing section, 3 is a memory for storing the image signal, and 4 is a modulator for modulating the image signal into a signal suitable for transmission. A modulation section 5 is a transmission control section for transmitting the image signal to the line 12.

A CPU 6 controls the entire facsimile apparatus according to a program stored in the ROM 7, and receives various operation requests such as transmission from the operation section 9, and controls the transmission control section 5 and the like.

8 is a RAM for storing control data, etc.; 10 is a mechanism control unit that controls a motor drive mechanism (not shown) of the original reading unit 1; and 11 is a system control unit for controlling a motor drive mechanism (not shown) of the document reading unit 1; This is a smoothing instruction switch for manually instructing whether or not to operate the smoothing function.

In FIG. 2, 20 is a reception control unit for receiving image signals and control signals from the line 12, 21 is a demodulation unit that converts the received modulated image signal into a signal suitable for processing within the apparatus,
22 is a memory for storing the demodulated received image signal.

25 is a CPU that controls the entire facsimile machine according to the program stored in the ROM 26, for example, by analyzing the control signal from the reception control section 20 and controlling the switching section 23, which will be described later. This is a RAM for storing data. Further, the CPU 25 receives information regarding implementation of the smoothing process from the transmitting side via the reception control unit 20, and based on the information, the CPU 25 controls the switching unit 23.
control. As a result, the received image signal stored in the memory 22 is subjected to smoothing processing in the smoothing processing section 24 by switching the switching section 23, and then transferred to the recording section 22.
9 or directly to the recording section 29.

In the recording section 29, a drive motor (not shown) for feeding recording paper is used.
The image is recorded under the control of the mechanism control section 28.

Next, the smoothing processing procedure in this embodiment will be explained with reference to the flowcharts shown in FIGS. 3 and 4.

FIG. 3 is a flowchart showing the processing procedure on the transmitting side. In FIG. 3, the CPU 6 waits for a transmission request instruction from the operation section 9 in step S1.

If there is a transmission request, the original is read in step S2, and the image signal is processed and stored in the memory in step S3. Then, when the accumulation of image beliefs is completed, in the following step S4,
The CPU 6 instructs the transmission control unit 5 to call the other party's facsimile, and in step S5 determines whether or not there is a smoothing processing instruction from the smoothing instruction switch 11.

If there is a smoothing processing instruction in step S5, the process proceeds to step S6, where smoothing processing ON is added as a pre-transmission procedure and sent to the other party's facsimile. If there is no instruction, a pre-transmission procedure with smoothing processing OFF is performed in step S7. In the subsequent step S8, transmission of the image signal is started, and after a determination of completion of transmission is made in step S9, a post-transmission procedure is performed in step S10, and the process ends.

FIG. 4 is a flowchart showing the processing procedure on the receiving side. In FIG. 4, in step S20, the reception control unit 2
0 performs reception processing such as incoming call processing in order to receive an image signal from the other party's facsimile machine via line 12. In step S21, the demodulation unit 21 demodulates the received image signal and the memory 22
The demodulated signal is stored in the

Next, in step S22, the CPtJ25
0 analyzes the control information received from the other party's facsimile and determines whether the smoothing processing instruction as a pre-procedure is ON or OFF.
Make a judgment. As a result, smoothing processing is turned on.
If so, the process advances to step S23, where the switching unit 23 is switched to the smoothing processing unit 24 side, smoothing processing is performed on the received image signal, and the processed image signal is sent to the recording unit 29.

However, the smoothing process is OF in step S22.
If F, the CPU 25 controls the switching unit 23 to directly send the image signal in the memory 22 to the recording unit 29 without going through the smoothing processing unit 24.

In step S24, the image signal is recorded in the recording unit 29, and if it is determined in the subsequent step S25 that the reception process is finished, a post-procedure is performed in step S26, and the process is finished.

Note that since the smoothing process is well known, a detailed explanation will be omitted.

As explained above, according to this embodiment, it is possible to select whether or not to perform smoothing processing on the receiving side depending on the type of transmitted image by operating a switch on the sending side of the original, and smoothing processing is not necessary. This has the effect of preventing the negative effects of smoothing processing on images.

In the above embodiment, a switch was provided for instructing smoothing processing on the sending side, but without providing a new switch, the halftone switch of the facsimile machine and the smoothing processing instruction are linked, and smoothing is not applied to halftone images. No processing may be performed.

[Effects of the Invention] As described above, according to the present invention, it is possible to select whether to perform or stop the smoothing process performed on the receiving side on the transmitting side, and it is possible to prevent image deterioration due to the smoothing process.
