Description

Description: TECHNICAL FIELD The present invention relates to a facsimile apparatus having a smoothing processing function.

[Prior Art] Conventionally, in this type of facsimile apparatus, the operation of the smoothing processing function performed by the receiving side cannot be controlled from the transmitting side.

[Problem to be Solved by the Present Invention] In the above conventional example, since the receiving side performs the smoothing process by the smoothing function uniformly regardless of the type of image,
There is a drawback that no smoothing processing is required, for example, processing is performed on a halftone image or the like, so that image deterioration occurs.

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

That is, instructing means for instructing whether or not to perform smoothing processing on the receiving side, transmitting means for transmitting the instruction from the instructing means to the receiving side as a pre-transmission procedure, and receiving an instruction from the transmitting means at the time of reception. Control means for controlling the smoothing processing function.

[Operation] In the above configuration, the implementation or non-execution of the smoothing processing function from the transmission side to the reception side can be controlled, and processing can be stopped for an image that does not require smoothing processing.

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

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

In FIG. 1, reference numeral 1 denotes a document reading unit for reading a document and generating image data, 2 an image signal processing unit, 3 a memory for storing image signals, and 4 a modulating the image signals into signals suitable for transmission. The modulation unit 5 is a transmission control unit for transmitting an image signal to the line 12.

A CPU 6 controls the entire facsimile apparatus in accordance with a program stored in the ROM 7.
, And controls the transmission control unit 5 and the like. Reference numeral 8 denotes a RAM for storing control data and the like, reference numeral 10 denotes a mechanism control unit for controlling a motor driving mechanism (not shown) of the document reading unit 1, and reference numeral 11 denotes a smoothing operation on the receiving side with respect to the receiving side. This is a smoothing instruction switch for manually instructing whether to operate the function.

In FIG. 2, reference numeral 20 denotes a reception control unit for receiving an image signal or a control signal from the line 12, reference numeral 21 denotes a demodulation unit for converting a received modulated image signal into a signal suitable for processing in the apparatus, and reference numeral 22 denotes a demodulation unit. This is a memory for storing the received image signal.

Reference numeral 25 denotes a CPU that controls the entire facsimile apparatus according to a program stored in the ROM 26, for example, analyzing a control signal from the reception control unit 20 and performing control of a switching unit 23, which will be described later. R for storing
AM. Further, the CPU 25 receives information on the execution of the smoothing process from the transmitting side via the reception control unit 20, and controls the switching unit 23 based on the information. as a result,
The received image signal stored in the memory 22 is subjected to smoothing processing by the smoothing processing unit 24 by switching of the switching unit 23, and then sent to the recording unit 29 or directly sent to the recording unit 29. In the recording unit 29, a driving motor (not shown) for feeding the recording paper is controlled by the mechanism control unit 28 to record an image.

Next, a smoothing processing procedure in the present embodiment will be described with reference to the flowcharts shown in FIGS.

FIG. 3 is a flowchart showing a processing procedure on the transmission side. In FIG. 3, the CPU 6 waits for a transmission request instruction from the operation unit 9 in step S1. If there is a transmission request, step S2
To read the original, and process the image signal and store it in the memory in step S3. Then, when the image signal has been stored,
In the following step S4, the CPU 6 instructs the transmission control unit 5 to call the other party facsimile. In step S5, the CPU 6 determines whether or not there is a smoothing processing instruction from the smoothing instruction switch 11.

If there is a smoothing process instruction in step S5, the process proceeds to step S6, where a smoothing process ON is added as a pre-transmission procedure and sent to the other party facsimile. If there is no instruction, a transmission procedure with the smoothing processing OFF added is performed in step S7. In the following step S8, the transmission of the image signal is started, and after the transmission end is determined in step S9, step S1 is performed.
If the value is 0, the post-transmission procedure is performed, and the process ends.

FIG. 4 is a flowchart showing a processing procedure on the receiving side. In FIG. 4, in step S20, the reception control unit 20
Performs reception processing such as incoming call processing for an image signal from the other party's facsimile via the line 12. In step S21, the demodulation unit 21 demodulates the received image signal and stores the demodulated signal in the memory 22.

Next, in step S22, the CPU 25 analyzes the control information from the other party facsimile received by the reception control unit 20, and determines whether the smoothing processing instruction as a pre-procedure is ON or OFF. As a result, if the smoothing process is ON,
Proceeding to S23, the switching unit 23 is switched to the smoothing processing unit 24 side, performs smoothing processing on the received image signal, and sends the processed image signal to the recording unit 29.

However, if the smoothing process is OFF in step S22, the CPU 25 controls the switching unit 23 to send the image signal in the memory 22 directly to the recording unit 29 without passing through the smoothing processing unit 24. In step S24, the image signal is recorded in the recording section 29. If it is determined in step S25 that the receiving process has been completed, the post-procedure is performed in step S26 to end the process.

It should be noted that the smoothing process is known, and therefore, detailed description is omitted.

As described above, according to the present embodiment, a switch operation on the transmitting side of a document causes a
You can select whether to perform smoothing processing on the receiving side,
There is an effect that an adverse effect of the smoothing process on an image that does not require the smoothing process can be prevented.

In the above-described embodiment, a switch is provided for instructing the smoothing process on the transmitting side. The processing may not be performed.

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