Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image communication apparatus used in, for example, a facsimile apparatus having an image information storage function.

2. Description of the Related Art A conventional device of this type includes a communication control means for communicating image information, a recording device for printing and recording image information, an image information memory using a magnetic disk storage device, and an image information memory. It has a picture information control means for managing the generated picture information in block units, and transmitted / received picture information is temporarily stored in a picture information memory and then transmitted or printed / recorded (for example, Japanese Patent Laid-Open No. -116362 gazette).

However, according to such a configuration, when an error is included in the image information read from the image information memory, it is useless as a recipient of the recorded document of the image information including the error. There is a problem that it may give a lot of confusion.

The above problem occurs for the following reasons.

That is, once the image information including an error and the image information not including an error are printed and recorded by the recording device, they cannot be distinguished. Even if there is a defect-like portion on the print screen of a printed and printed document, that is, a hard copy, it is difficult to determine whether or not the portion is caused by the above error by comparing with the original document. For this reason, on the side that receives only the hard copy of the image information including the above-mentioned error, the user may feel distrust of the contents of the recording screen having the defective portion, or may be confused by the defective portion.

In order to avoid the above-mentioned problem, it is possible to suspend recording or transmission of image information until the error is corrected. However, if this is done, smooth processing of the image information will be hindered, and if some errors cannot be corrected, the entire image information file will become unavailable due to some of these errors. There is another problem that may happen.

The present invention has been made in view of the above problems, and creates a recorded document that does not cause unnecessary confusion to the recipient even if the image information read from the image information memory contains an error. An object of the present invention is to provide an image communication device capable of performing the above.

Means for Solving the Problems In order to solve the above problems, the present invention manages image information stored in an image information memory in block units, and
A page to which the image information block determined to have an error is determined while determining whether or not there is an error in the image information block read from the image information memory and selectively eliminating the image information of the image information block to which an error determination has been applied. The present invention is provided with a structure for adding image information indicating that there is an error. Action The present invention, when the image information including an error is printed by the above-described configuration, normal image information is printed. Since the display indicating that there was an error will be printed together with the part, even if the image information read from the image information memory contains an error, it will cause unnecessary confusion to the recipient. It is possible to create a document that does not need to be recorded.

Embodiment FIG. 1 shows a schematic configuration of an image communication apparatus according to an embodiment of the present invention, in which 1 is a communication line, 2 is a communication control unit, 3 is an image information memory, 4 is an image information control unit, 5 is a management memory for storing management information of image information, 6 is an error determination circuit, 7 is an error processing section, 8 is an image information generating section, 9 is a recording device, 10 is a system control section, 11 is a data bus, 12 Is an image information transmission path.

In FIG. 1, a communication control unit 2 communicates image information with a terminal connected via a communication line 1.

The image information memory 3 is configured by using a relatively large-capacity storage device such as a magnetic disk device, and stores transmitted / received image information in block units.

The image information control unit 4 manages the image information stored in the image information memory 6 in block units. The image information is divided into image information blocks of a predetermined size and stored in the image information memory 3. The image information control unit 4 also manages the page to which each information block belongs.

The management memory 5 provides an image information management area in which management information of the image information stored in the image information memory 3 is stored and registered. The management memory 5 is formed by renting a part of the storage area of the image information memory 3 or using a separately provided nonvolatile RAM. The management information includes file information for managing the image information for each file, page information for searching the image information in the file for each page, and block information for managing the image information in the page in block units. is there.

The error determination circuit 6 determines whether or not there is an error in the image information block read from the image information memory 3. The type of error determined by the error determination circuit 6 includes, for example, an error that occurs on a disc that is a recording medium, an error that occurs in the process of encoding or decoding image information, and the like.

The error processing unit 7 selectively removes the image information of the image information block for which an error has been determined, and adds image information indicating that there is an error in the page to which the image information block for which an error has been determined belongs.

The image information generation unit 8 generates error display image information added by the error processing unit 7, for example, image information displaying a comment sentence such as “Disk Error”. The image information generation unit 8 is configured by using, for example, a ROM in which a standard image information pattern is written, and selectively outputs a plurality of types of error display image information according to the error content.

The recording device 9 prints and records the image information once stored / accumulated in the image information memory 3 on a recording paper.

The system control unit 10 is configured by using a general-purpose information processing device having a microcircuit, a so-called microcomputer, and controls the entire device including the recording device 9.

FIG. 2 shows the block information registered in the management memory 5 and the storage configuration of the image information blocks stored in the image information memory 3. As shown in the figure, the image information blocks stored in the image information memory 3 are managed by the block numbers registered in the management memory 5.

The operation of the image communication apparatus configured as described above will be described below.

FIG. 3 is a flowchart showing an operation example of the image communication apparatus described above.

In FIGS. 1, 2 and 3, when the image information stored in the image information memory 3 is read and printed and recorded in the recording device 9, first, the management information for one page is read from the management memory 5. (S1). One image information block is read from the image information memory 3 based on the read management information (S2).

The read image information block is transferred to the error determination circuit 6, where it is determined whether or not there is an error (S3).

When it is determined that there is an error, the image information of the read image information block is eliminated (cancelled) (S11).
Along with this, the fact that there was an error is registered (S1
2).

If it is determined that there is no error, the read image information block is directly transferred to the recording device 9 and printed and recorded (S4).

When the recording of the image information block transferred to the recording device 9 is completed (S5), it is checked whether or not the end of the page has been reached (S6).

If it is not at the end of the page, the next image information block is read (S2), and the same process is repeated for the read image information block (S3 to S6, S11, S12).

When the end of the page is reached, it is checked whether or not there is an error registration (S12) (S7).

Here, if there is an error registration, the error display image information generated from the image information generation unit 8 is added to the input image information of the recording device 9 (S13). As a result, the recording device 9
Together with the image in the image information block, for example, "Disk F
Also record an error display image such as "rror".

On the other hand, if there is no error registration, the error display image is not recorded.

As described above, the image information block for one page is read out, and only the information of the block having an error is selectively excluded from the read out and printed. And
Only when there is an error in the page, error display image information that indicates that there is an error is added, and a comment indicating that there is an error in the document page in which the image information including the error is recorded Is also recorded.

After this, it is checked whether there is a next page (S
8). If there is a next page, the management information of the next page is read and the above-described series of processing (S1 to S8, S11 to S1
3) is repeated. If there is no next page, the operation is terminated and the next operation is started.

FIG. 4 shows a recorded document A having no error in the page and a recorded document A ′ in which an error (disk error) occurs in the page and an error display image “Disk Error” is recorded. Although the recorded document A ′ in which the error has occurred has a defect in a part of the recorded image, since the error display image information “Disk Error” is recorded, the person viewing the document has a defect due to the error. You can foresee what may be, which avoids unnecessary confusion.

As described above, in the apparatus of the above-described embodiment, when the image information including an error is printed and recorded, the normal image information portion and the display indicating that there is an error are also printed and recorded. Even if the image information read out from the information memory 3 contains an error, it is possible to prevent unnecessary confusion in the recipient of the recorded document.

In the operation example shown by the flowchart in FIG. 3, the image information to which the error display image information is added is printed and recorded in the recording device of the own station, but the image information to which the error display image information is added is recorded. The same effect can be obtained by transmitting the data to another terminal via the communication control line 1 and printing and recording the data there. In this case, the error display image will be recorded in the document printed and recorded at the destination of the image information, so that the recorded document at the destination can be recorded without the need to make a separate contact. You can notify the recipients of the error and the page with the error.

As is apparent from the above description, the present invention manages the image information stored in the image information memory on a block-by-block basis and determines whether the image information block read from the image information memory has an error. Whether or not the image information of the image information block for which an error has been determined is selectively eliminated, and image information for indicating that there is an error in the page to which the image information block for which an error has been determined is added is added. , When the image information including an error is printed and recorded, the normal image information part and the display indicating that there is an error are also printed and recorded, so the image information read from the image information memory Even if an error is included, it is possible to create a recorded document that does not give unnecessary confusion to the recipient.
