Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a device, such as a facsimile machine, that inputs, stores, and transmits image information.

[Background of the invention]

An example of a conventional facsimile device is, for example, Journal of the Institute of Image Electronics Engineers, 1984, vot, 13+A5. It is shown on page 456.

The above-mentioned conventional technology does not consider a means for confirming whether or not the information intended by the operator of the device with the scanner or the creator of the document image input by the scanner is input as image information. .

For this reason, (1) Due to the structure of the scanner, the surface of the document being scanned cannot be visually observed.

■As a result of binarizing the input image information, it cannot be confirmed whether the binary signal properly represents the contents of the manuscript.

■It is difficult to determine what parameter settings should be used to obtain appropriate image quality.

0 It is not possible to confirm whether the image information was reliably sent to the other party.

There are nine other problems.

An object of the present invention is to reliably input and store image information of the content intended by a device operator or document creator.

The purpose is to provide a means for transmission.

[Purpose of the invention]

The above object can be achieved by providing a display device for displaying part or all of the image information input by the scanner.

[Summary of the invention]

This display device displays image information obtained by, for example, the following means.

■Image information input using manuscript gold, optical means, or photoelectric conversion means.

(2) Image information obtained by decoding the code word that is the result of encoding the image information input by the above means again.

(2) Image information obtained by transmitting a code word resulting from encoding processing to a receiving device via a transmission path using a transmission means, and then sending back information with the same content from the receiving device.

By displaying this image information, it is possible to confirm that the document content has been input, stored, or transmitted with certainty, and therefore the operability and reliability of the device that performs this operation can be significantly improved.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

Figures 1 and 2 show seven examples of system configurations for implementing the present invention.
(taking an axis device as an example). Manuscript 10
0 is line-sequentially scanned and input by the sensor 120 through the entire optical system 110, and this input signal is subjected to shading correction etc. in the pre-processing circuit 130, then converted into a code word in the encoding circuit 140, and then sent to the transmission circuit 150. and sends it out to the transmission path. On the other hand, the signal from the transmission path is input to the receiving circuit 330, and the signal is input to the decoding circuit 330.
The image information is restored in step 20, and a recording circuit 310 drives the recording head 305 to create a recorded image 3001. Image information output from the preprocessing circuit 130, image information output from the decoding circuit 320, operating method instruction information output from the control circuit 230, etc. are stored in a storage device 220 for temporarily storing image information for display. , is displayed on the display device 200 using the drive circuit 210.

The control circuit 230 converts the multivalued image information output from the preprocessing circuit 130 and stored in the storage circuit 220 into predetermined parameters according to the signal processing procedure shown in FIG.
Alternatively, by executing the binarization process based on parameters set by the operator and displaying the result on the display device 200, the binarization threshold, line density, filter coefficient, etc., for obtaining appropriate image quality, Parameters such as dithering buttons can be selected, and by setting this result in the preprocessing circuit 130, the multivalued signal from the sensor 120 can be sequentially binarized using the above parameters. .

Further, a transmission signal from a transmitting device connected to the other end of the transmission path is inputted to a receiving circuit 330, and image information reproduced by a decoding circuit 320 is transmitted to a recording circuit 310 and a recording head 30.
The content of the sent image information can be confirmed by displaying it on the display device 200 at the same time as or prior to creating the recorded image 300 in step 5.

Furthermore, in order to determine whether the image information has been reliably transmitted from the transmitting device to the receiving device, the information received by the receiving device is sent back to the transmitting side again and this information is displayed on the display device 200. This determination can be easily realized. In this case, regardless of whether the transmission system is duplex, half-duplex, or full-duplex,
It goes without saying that the objective can be achieved by adjusting the transmission system.

In particular, when a full-duplex transmission system is used, the image information transmitted by the transmitting device and the image information received by the receiving device can be simultaneously sent, received, and compared, making it possible to achieve reliable information exchange. .

The display device 200 not only displays the content of image information, but also displays instructions for how to operate the device for the device operator, displays the operating procedure of the device, and displays characteristic properties of the image information (density distribution one character and It is possible to display the type of characters recognized from the input image information.

Further, by inputting the operation signal of the control circuit 230 using a sensor configured integrally with the display device, the display contents can be switched, and the same sensor can be used as a selection means for different types.

As a sensor for this purpose, a light transmission type pressure sensor, an ultrasonic sensor for position detection, an optical sensor that detects light from a light source traveling parallel to the front surface of the display device, etc. can be used.

Further, the display device 200 may include a CRT, liquid crystal, plasma, L
It can be configured with an ED (light emitting diode) or the like.

As described above, by using the present invention, it is possible to check the contents and give instructions on how to operate the device by displaying image information, but these functions operate adaptively depending on the type of document and individual differences of the operator. It is desirable to do so.

For example, when communicating important documents, it is essential to confirm the contents. On the other hand, detailed operating instructions are not required for experienced operators.

Such adaptive operation can be selected using a switch provided on an operation panel or the like. In addition, OMR (optical
This can be achieved by filling out the mark reader) sheet, 0CR (optical character league) sheet, etc. Further, it is possible to cause the device to perform adaptive operations using a magnetic card, an IC card, or the like in which the identity, affiliation, skill level, etc. of the operator are input in advance.

〔Effect of the invention〕

According to the present invention, image information obtained by input means, storage means, transmission means, etc. can be displayed, so image information of appropriate image quality can be reliably input, stored, or transmitted. can.
