Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a JBIG (Joint Bi-level Image Grou) coding system.
p) The present invention relates to a facsimile machine having a function.

[0002]

2. Description of the Related Art In recent years, in a facsimile apparatus having a JBIG function, there are two types of binary image encoding methods, progressive build-up and sequential build-up, which are freely used depending on the apparatus.
In particular, even when the receiving side has two methods, it is configured to receive according to the JBIG method instructed by the transmitting side regardless of the presence or absence of a display device for displaying image information such as a received image.

Further, even when the image is received by progressive build-up, there is a configuration in which the received image is temporarily stored in the memory and then displayed from the top or the entire image at once.

Further, in this type of apparatus, there is no function for the user on the receiving side to determine the print output resolution of the received image, and the resolution of the received image is as received or the device arbitrarily changes the resolution. Is printed out.

[0005]

However, in the above-mentioned conventional example, when the received image is received by the sequential buildup, if the received image is displayed in real time, the entire image of the received image is not displayed, but the received image is displayed vertically or horizontally. There is a problem in that it is displayed from one end, and it takes time for the user to understand the outline of the received image, and the display device for the received image cannot be effectively used.

Further, even after the reception is completed by the progressive build-up and then the data is decoded and displayed, it takes time until the user can understand the outline of the received image, so that the display of the received image can be effectively used. There was also a problem that I could not do it.

Furthermore, since the apparatus prints out the image information received by the progressive build-up at a resolution arbitrarily decided by the apparatus, even the information that the user does not need in detail is finely displayed, and the receiving side user is easy to use. There was also the problem that it was not good.

Further, in the above-mentioned conventional example, there is a drawback that it is difficult for the user to understand the progress of the image transmission and reception. In particular, in a facsimile machine that transmits or receives using hierarchical encoding, the communication state and the state of the original or recording paper do not match because the transmission state is first stored in the memory and then transmitted or printed. Is getting stronger.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a facsimile apparatus with improved convenience for users.

[0010]

In order to achieve the above object, the facsimile apparatus of the present invention has the following configuration.
That is, a facsimile device having a progressive build-up function, a display unit for displaying image information,
When displaying on the display means, there is provided control means for controlling to display using progressive build-up.

[0011]

With the above arrangement, the present invention can improve the convenience of the user by controlling the image information to be displayed using the progressive buildup when the image information is displayed on the display means.

Then, each time the keys 45 to 47 are pressed, the resolution corresponding to the display unit 42 is displayed.

Next, the control procedure of the facsimile apparatus in the embodiment will be described below with reference to the drawings.

FIG. 5 is a flowchart showing the incoming call processing executed by the CPU 11, which is stored in the ROM 12. First, in step S51, an incoming call from the calling side is detected by the data communication unit 110, and when there is an incoming call, the process proceeds to step S52, and the calling side terminal and the mutual function are negotiated according to the communication protocol. Then, in step S53, it is determined whether or not the calling terminal intends to perform transmission by progressive build-up according to the result of the negotiation. If it is determined that the other party desires progressive build-up coding, the process proceeds to step S54 to accept the incoming call. However, if the other party does not desire progressive buildup, step S55.
Process and reject the call.

It should be noted that when the calling terminal is not progressive build-up coding, the incoming call is rejected.
There is no problem if you receive the call as usual.

FIG. 6 is a flow chart showing the flow of the received image data by progressive build-up and sequential build-up in the embodiment. First, in step S61, similarly to step S53 described above, it is determined whether or not the progressive buildup encoding is performed. Progressive build-up encoding is such that, as is known, low-resolution image data for one page is transmitted, and then one-rank higher resolution page data is transmitted.
It is configured to send page data hierarchically.
Here, if it is determined that the progressive buildup has been performed, the process proceeds to step S62 to determine whether or not the received image data for all resolutions encoded by the progressive buildup has been displayed. As a result, if all the resolutions are displayed, the reception process is terminated, and the process shifts to a print output process or a process of notifying the user with a lamp, a sound, or the like.

On the other hand, if not all the resolutions are displayed, the process proceeds to step S63 to receive the image data from the transmitting side, and in the subsequent step S64, the received image data is stored in the data storage memory 16 until one resolution is accumulated. accumulate. Next, in step S65, it is determined whether or not image data of one resolution has been received. If not received, the process returns to step S62, and the above-described data receiving process is repeated. However, if the reception is completed, the process proceeds to step S66 to decode the image data for one resolution, and in step S67, the decoded data is displayed on the external display unit 18. Then, the process returns to step S62, and the above-described process is repeated.

On the other hand, if it is determined that the received image is not progressive buildup, the process proceeds to step S68 to perform a normal receiving process. First, step S68
Then, it is determined whether or not the data reception is completed, and if it is determined that the reception of all the data is completed, the process proceeds to step S611. However, if reception has not ended, the process proceeds to step S69 to continue the image data reception process, and in step S610, the received image data is stored in the data storage memory 16. After that, the above reception and storage processing is repeated until the reception is completed. If the reception is completed in step S68, the process proceeds to step S611, the image data for one page is decoded, and in step S612,
The decrypted page data is displayed on the external display unit 18.

That is, in the normal reception, when the received image is displayed on the external display unit 18, the data for one page is accumulated and then the decoding and the display are performed, whereas the progressive build according to the embodiment is performed. Up image reception,
After decoding the received one-page information, the page information per one resolution is displayed.

In FIG. 6, the case of receiving one page of image data has been described as an example, but it is needless to say that the present invention can be applied to the case of receiving a plurality of pages.

In addition, during normal reception, a method of sequentially decoding the received image information and gradually displaying it is also possible, as in the method of (a) shown in FIG. The display at that time is
Since it is displayed from one end of the top and bottom, and it is not understandable that the whole image of the image is not received until the end of the data, it is generally slower than the progressive buildup. Further, when decoding the progressive buildup, the data for one resolution is waited for, but it is also possible to sequentially decode and display the received images.

FIG. 7 is a flowchart showing the control procedure of the CPU 11 when the user determines the print resolution and prints out after receiving the image coded by the progressive buildup.

First, in step S71, it is determined whether or not all the received image data has been displayed. If nothing has been received yet, the process proceeds to step S72, and the line 1
The image data sent through 11 is received for each frame. Then, in step S73, the image data is extracted from the received frame and stored in the data storage memory 16. Next, in step S74, it is determined whether or not page data for one resolution of progressive buildup has been received, and if image data for one resolution has not been received, the process returns to step S72 to receive the above-described data reception. And the storage process is repeated. However, if the reception is completed, the process proceeds to step S75, the received data for one resolution is decoded, and in the next step S76, the decoded data is displayed on the external display unit 18. Then, step S7
The process is returned to 1 and the above process is repeated.

Next, when it is determined in step S71 that the display of all data has been completed, the process proceeds to step S77, and the print resolution of the received image is selected by the user. Specifically, the print resolution selection keys 45 to 47 shown in FIG. 4 are pressed to select a clear image or a rough image. Then, in step S78, an image conforming to the selected print resolution is displayed as the display example 43, and in step S79, it is determined whether or not the resolution has been determined. This process is a process which is regarded as the resolution determination when, for example, a set key or the like (not shown) is pressed, or when no key is pressed for 10 seconds after the print resolution selection keys 45 to 47 are pressed. Then, steps S77 and S78 described above are repeated until the print resolution is determined. When the resolution is determined, the process proceeds to step S710, and the data output unit 19 prints out the resolution determined.

In FIG. 7, the print resolution is determined after receiving all the data, but the print resolution may be determined in advance before or during image reception.

FIG. 8 and FIG. 9 are views for explaining the processing when displaying the image data stored in the data storage memory 16 on the external display unit 18.

FIG. 8 is a diagram showing a flow of displaying the image data stored in the data storage memory 16 on the external display unit 18. In FIG. 8A, after the image data is stored in the data storage memory 16 by the progressive buildup, the data is displayed on the external display unit 18. That is, the image stored in the data storage memory 16 is decoded into a raw image, and then L
It is displayed on the external display unit 18 such as a CD. In FIG. 8B,
FIG. 7 is a diagram showing an example of a case where image data is stored in a data storage memory 16 by a compression method different from progressive buildup such as MMR. First, image data for one page or one document is retrieved from the data storage memory 16 and decrypted. Next, the image data converted into a raw image is subjected to image conversion by JBIG progressive buildup. Here, the reason for performing compression by progressive buildup is that the external display unit 18
This is because the progressive build-up function is used to gradually display the entire image of the displayed image in more detailed parts.
The part that performs the processing is the data encoding part. next,
The data is sequentially stored in the data storage memory 16 from the end of decoding, or the data is decoded for each part at a timing such as a key input by the user and displayed on the external display unit 18. is there. This operation is repeated until there is no image data for displaying the operation for reading a certain block from the storage memory 16, and the processing is considered to be completed.

FIG. 9 is a CP for displaying the image data stored in the data storage memory 16 on the external display unit 18.
It is a flow chart which shows control of U11. First, in step S91, a request for displaying the data in the data storage memory 16 on the external display unit 18 is accepted. The main reception may be keyed in by the user, or may be a process in which the CPU 11 performs display after a certain period of time after reception. Next, in step S92, the data storage memory 1
The coding type of the image data in 6 is checked, and in step S93, it is determined whether the coding is performed by progressive build-up according to the result. Here, in the case of compression by progressive buildup, step S97
If so, the process proceeds to step S94.

In step S94, a process of returning the compressed data to a raw image is performed. The data storage memory 1
If the raw image is stored in advance in step 6, step S
Step 94 is skipped and the process proceeds to step S95. In step S95, the raw image is compressed by the progressive buildup encoding, and in step S96, the progressive buildup data is stored in the data storage memory 1.
Accumulate to 6.

Next, in step S97, the image data for one resolution is read from the data storage memory 16, and in the following step S98, the data is decoded. Then, in step S99, the decrypted data is displayed on the external display unit 18, and in step S910, step S9
It is determined whether or not the data read in 7 is the last block. As a result, if it is determined that the data is the final data, this process ends, and if it is not the final data, step S97.
The processing is returned to, and the above-mentioned reading processing from the memory is repeated.

In the above-mentioned embodiment, the procedure of displaying the image information encoded by the progressive build-up on the external display 18 at the time of reception has been described. However, the normal compression, for example, the MMR specified by CCITT recommendation, etc. The encoded data is also normally received, then temporarily stored in the data storage memory 16, encoded by MMR, further encoded by progressive buildup, and gradually decoded from a low resolution. However, it may be displayed on the external display 18.

As described above, according to the first embodiment, in a facsimile apparatus having a display capable of displaying a received image or the like, a detailed portion can be displayed by displaying on the display by the progressive buildup function of JBIG. Even if the user does not need it, it is possible to provide the user with an easy-to-use device, such as easily canceling. Furthermore, by displaying the progressive build-up encoded image data in real time at the time of reception, the user on the receiving side can be immediately notified of the outline of the document, which is convenient. Further, when outputting a received image or the like, an output resolution input section is provided, and the user inputs the resolution for print output, and prints at the input resolution, so that only detailed information or general information is obtained. The output can be separated from the output by the user, and a user-friendly interface can be provided.
