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

FIG. 1 is a block diagram showing the arrangement of an image processing apparatus according to the first embodiment of the present invention. In the figure, a wireless telephone device 1 communicates through a public telephone line by using mobile communication services of communication companies.
The network control unit 2 controls the wireless telephone device 1 when making or receiving a call. The ear microphone 3 is a microphone and a speaker attached to the head of the operator, and is used during a call. The modem 4 modulates / demodulates image information and transmits / receives various procedure signals for facsimile communication. The communication control unit 5 controls the modem 4 to transmit image information according to the transmission control procedure of the G3 standard facsimile. The communication control unit 5 is provided with an encoding / decoding means DCR that compresses image information and restores the original image information.

The tablet image input / output unit 6 displays the document image information page by page and allows the operator to arbitrarily input characters and figures by pen-touch operation.
The page memory 7 temporarily stores the sent / received document image information. The frame conversion unit 8 reads out image information for one screen to be displayed from the document image information within one page of the page memory 7 and outputs it to the frame memory 9.
On the contrary, the image information for one screen in the frame memory 9 is transferred to a predetermined position in the page memory 7. The frame conversion section 8 is provided with a scaling means for enlarging or reducing the image size when reading out image information for one screen from the document image information.

The digital / NTSC converter 10 converts the above-mentioned document information, which is digital information, into an NTSC (Nationala).
l Television System Commi
Tee) television image signals and vice versa. Screen display unit 11
Is for displaying an image on the screen. The video tape deck 12 records and plays back images using an 8 mm video tape cassette, and is a known device generally used for recording and playing back images picked up by a video camera or television images.

The voice recognition unit 13 recognizes a telephone number spoken by the operator. The operation display unit 14 is for displaying various information such as the operating state of the device as the user performs various operations. The system control unit 15 is a microcomputer that monitors and controls each of the above units.

With the above configuration, the image processing apparatus of this embodiment has a telephone function, a function of transmitting and receiving an image to and from a facsimile apparatus of G3 standard, and a function of accumulating the image.

Next, the operation when an image is received from another facsimile apparatus will be described. In this case, as shown in FIG. 2, the operator makes and receives a call by the telephone function to establish a call state with the other party operator. That is, for example, now
To make a call, the operator wears the earphone 3 and says the callee telephone number. Then, the voice recognition unit 1
3 recognizes the telephone number from the utterance sound. The system control unit 15 controls the network control unit 2 according to the recognized telephone number to make a call to the other party. In the case of an incoming call, it responds to the ringing of the wireless telephone device 1. As a result, a call is established with the other party (process 101).

The operator confirms that the image is received in the call, and activates the receiving operation of the image processing apparatus (process 102).

When the receiving operation is started, the image processing apparatus
The image information is received by executing a predetermined transmission control procedure with the destination facsimile machine. Since the received image information has been encoded, it is decoded and restored to the original image information. The restored image information is stored in the page memory 7. If the received image information has a plurality of pages, the received image is stored in the page memory 7 for all pages (process 103). The page memory 7
The image stored in is displayed by the tablet image input / output unit 6 page by page. Then, when the image reception ends, the communication operation ends. Then, in accordance with the operation of the operator, various image processes described later are executed (process 10).
4).

By the way, in this embodiment, the horizontal resolution of one screen is set to 450 lines and the vertical resolution is set to 525 lines, and images are displayed by the line interlace system.
For this purpose, the frame memory 9 is, as shown in FIG.
It has two memories for odd lines and even lines, each having a resolution of 450 × 262.5 lines.

In this embodiment, 8 × 8 (dot / m
Image information of an A4 original having a resolution of m), that is, image information of horizontal 1728 dots and vertical 2280 dots per page is processed. As shown in FIG. 4, the image of one page is divided into four sections in the X direction and nine sections in the Y direction, and is divided into 36 frames F11 to F49, and one frame is divided into horizontal 432 and vertical 256. Dot is set. It should be noted that the top four frames F19, F29, F3 in the Y direction are
9 and F49 have 432 horizontal dots and 232 vertical dots.

FIG. 5 shows the operations of the various image processes described above. That is, when this process starts, first,
From the image information of each page of the page memory 7, one frame, that is, 432 × 256 dot image information is read out and transferred to the two memories for the odd line and the even line in the frame memory 9 (process 201).

The digital / NTSC converter 10 converts the image information of each memory into an image signal of an NTSC television. The screen display unit 11 displays an image according to the image signal (process 202). At this time, the screen display unit 11 displays an image of 432 × 256 effective pixels on a screen having a resolution of 450 × 262.5 lines.

The operator performs a desired operation on the operation display unit 14 while looking at the displayed image. For example, when it is desired to change the display image, a scroll operation or a page break operation is performed. If the display image is desired to be enlarged or reduced, a zoom operation is performed. Furthermore, when it is desired to add an image to the displayed image, a desired page is displayed on the tablet image input / output unit 6, and characters or figures are arbitrarily handwritten on the displayed image by pen touch. ..

Further, when it is desired to save the currently displayed document information for one case, an image recording operation is performed. Further, when it is desired to send to another facsimile apparatus, a sending operation is performed.

Now, it is assumed that the operator performs a scroll operation or a page break operation. In this case (Y in process 204), the image processing apparatus moves the read area of the page memory 7. For example, in the case of a scroll operation, the read area is moved in the designated direction within one page. In this case, instead of moving in the unit of frame shown in FIG. 4, it moves in the unit of 1 dot in the X and Y directions while maintaining the range of 432 × 256 dots. Further, in the case of a page break operation, it is set to read a certain area of another page (process 205). Then, the image information in the above range is read at the destination and displayed in the same manner (Process 2).
01).

If a zoom operation is performed (Y in process 206), the scaling operation in the frame conversion unit 8 is set according to the scaling direction (process 207). Then, when reading the image information from the page memory 7 again,
Enlargement and reduction operations are performed on the image information, and the scaled image information is stored in the frame memory 9 (to process 201).
As a result, the display image is enlarged or reduced.

Next, when an image is additionally recorded by the tablet image input / output unit 6 (Y in step 208), the image information of the additional image is added to the image information in the page memory 7 (step 209). Then, the added image is displayed (process 2).
01).

Next, when an image recording operation is performed (Y in step 210), the image information in the page memory 7 is recorded on the video tape. That is, in this case, first, the image information of one page of the page memory 7 is reduced to the image information of one frame of 432 × 256 dots and stored in the frame memory 9. At the time of this recording operation, header data is set in the first line of the image information of each frame, as shown in FIG. 6A. As shown in FIG. 2B, this header data is prefix data indicating that it is header data, date, page of image, X address and Y address which are frame positions within one page, and for data check. It is configured by the CRC code. The prefix data in this case is set to a code not found in the data pattern of image information.

The digital / NTSC converter 10 converts the image information of the frame memory 9 into the image signals of each frame of the odd line and the even line, including the header data, as in the case of the image display. And video tape deck 1
2 repeatedly records a fixed number of image signals of each frame, as shown in FIG. The frame image in this case is recorded by a normal recording method of 8 mm video.

Next, the frame conversion unit 8 reads out the image information in the page memory 7 frame by frame in accordance with the section shown in FIG. 4 and stores it in the frame memory 9. At this time, similar to the above, predetermined header data is set in the image information of each one frame. Then, the frames F11 to
The image information of each frame up to F49 is sequentially converted into an image signal, and a fixed number of each is repeatedly recorded as in the above.

When the recording of the image information for one page is completed, a certain interval gap, that is, an interval in which no image signal is recorded is formed. This gap is formed to indicate the boundary of the page and to prevent the next image signal from being recorded on the image signal just recorded. Then, when the image information of the next page is present, the same recording operation is executed again (the processing 211).

Next, when the transmission operation is performed (Y in process 212), the transmission process is executed according to the operation of the operator. That is, FIG. 7 shows this transmission process, in which the operator makes and receives a call by the telephone function and has a talk with the partner operator as in the case of the reception process (process 301). Then, the transmission operation is activated (process 302).

When the transmission operation is activated, the image processing apparatus executes a predetermined transmission control procedure with the destination facsimile apparatus. Then, the image information stored in the page memory 7 is compressed and sequentially transmitted page by page (process 30).
3).

After the image recording and the image transmission are executed, the operation input state of the operator is returned (process 203). This allows the operator to arbitrarily repeat various processes. Then, when the operator performs a termination operation (process 2)
12), and the above processing ends.

Next, the reproducing operation of the recorded image will be described.

In this case, as shown in FIG. 8, the operator first specifies the image file to be reproduced. For this designation, for example, the reading position of the video tape is set to the document information 1
It is performed by advancing or returning by the number of cases (process 40).
1).

The video tape deck 12 sequentially reads out the image signal of the corresponding document image information by the designation operation,
Outputs NTSC image signals. This image signal is displayed on the screen display unit 11. Further, the digital / NTSC conversion unit 10 sends the image signal frame by frame at 432 × 2.
It is converted to image information of 56-dot digital information and stored in the frame memory 9 (process 402). At this time, the header data is stored as the image information of the first line.

The frame conversion unit 8 uses the header data X,
The frame position in one page is determined by the Y address, and the image information of the one frame is sequentially transferred to the corresponding area of the page memory 7 (process 403).

Such transfer processing is repeated for all frames and all pages (N from step 404 to step 402).
What). When the transfer process ends (Y in process 404),
Various image processes described in FIG. 5 are executed on the image information (process 405).

As a result, the operator can execute arbitrary processing such as displaying and transmitting an image reproduced from the video tape.

As described above, in this embodiment, in the image processing apparatus for displaying and transmitting the text information, the text information is recorded on the video tape by the video tape deck 12.

In general, a video tape deck is smaller and more resistant to impacts than an optical disk device and the like, and both the device and the video tape are inexpensive. As a result, it is suitable for carrying and the cost can be reduced.

Further, the image is converted into an image signal of the NTSC system, the image is recorded by the normal video tape deck 12, and a plurality of the same frames are continuously recorded.
As a result, the video tape recorded by this device can be played on another video tape recorder. Further, in this case, since a plurality of the same frames are continuously recorded, it becomes easy to stop the image one frame at a time as needed. Further, with this image processing apparatus, it is possible to reproduce moving images such as captured images of video cameras and recorded television images.

Since the received image of one page is divided into a plurality of frames to be displayed or recorded,
The original image can be faithfully reproduced without reducing the resolution of the image.

On the other hand, since the image processing apparatus of this embodiment is not provided with a device for reading a document image or recording and outputting it on a sheet, the device can be further downsized accordingly. Further, the screen display unit 11 can display an image at an arbitrary position within one page by scrolling and can arbitrarily enlarge or reduce the image, so that the image can be recorded and output on a sheet. Even without it, the operator can easily read the displayed image.

Further, since the facsimile apparatus has a function of communicating with the facsimile apparatus, the original image to be input can be read by another facsimile apparatus, received and input from the facsimile apparatus, and the image to be recorded and output on the sheet can be It can be transmitted to another facsimile machine and can be recorded and output by the facsimile machine. Moreover, since a handwriting operation can be performed on the input image by handwriting operation of the tablet image input / output unit 6, the operator can use it in the same manner as when writing a document on a sheet.

As described above, various kinds of processing can be performed without using original paper or recording paper, so that it is possible to realize paperless for resource saving.

FIG. 9 is a block diagram showing the arrangement of an image processing apparatus according to the second embodiment of the present invention. In the figure, the same reference numerals as those in FIG. 1 indicate the same devices or portions. In this embodiment, a D / A conversion section 16 is newly provided, and the operation display section 14 has a keyboard 14a and a display 14b. It has and. The D / A converter 16 is for converting a digital signal into an analog signal in a voice band and vice versa. The keyboard 14a is
Various kinds of character information are input, and the display 14b displays various kinds of character information. The earphone 3 and the voice recognition unit 13 arranged in FIG. 1 are deleted.

Next, the operation of the image processing apparatus of the present embodiment having the above-described structure for receiving an image and recording the received image on a video tape will be described.

In this case, as shown in FIG. 10, the operator activates the receiving operation after making and receiving the call with the wireless telephone device 1 (process 501).

When the image processing apparatus is activated, it executes a predetermined transmission control procedure with the destination facsimile apparatus and receives image information. Since the received image information has been encoded, it is decoded and restored to the original image information. The restored image information is stored in the page memory 7. When the received image information has a plurality of pages, the image information of all pages is stored in the page memory 7 (process 502). Then, the image of the first page stored in the page memory 7 is displayed on the tablet image input / output unit 6 (process 503). When the image reception is completed, a predetermined communication ending procedure is executed to end the communication.

The operator confirms the received image displayed and, if necessary, performs a page break operation on the operation display unit 14 or inputs a handwritten image on the tablet image input / output unit 6. When the page break operation is executed, the display image of the tablet image input / output unit 6 is switched page by page. Also,
The image input by handwriting is additionally written on the received image (process 504).

When the operator wants to save the received image (Y in step 505), he / she operates the operation display unit 14 to input additional character information such as the content of the received image and comment information (process). 506). Then, the recording operation of the video tape deck 12 is started. This allows
The image processing device records the received image and the additional information on a video tape.

Next, this recording operation will be described.

As shown in FIG. 11, the video tape used in the video tape deck 12 has a video track VT formed at the center and an audio track A on one side thereof.
A control track CT is formed on each of T and the other side portion. The video track VT is a track for recording images, and the audio track AT is a track for recording audio signals. The control track CT is a track for recording a synchronizing signal of an image.

When recording an image on a video tape, the image processing apparatus first reduces the image of one page as a whole and converts it into an image signal of one frame of the NTSC system, as in the above-described embodiment, and an even frame. And the image signals of odd-numbered frames are generated. Then, as shown in FIG. 12A, the image signals of the even frame and the odd frame are repeatedly recorded in a fixed number on the video track VT of the video tape. At the same time as the recording of the image signal, a predetermined synchronization signal is recorded on the control track CT.

Now, the received image is A4 size 8 × 8
Assuming that the image has a resolution of (dots / mm), the image of one page is displayed in the frame F11 as described in FIG.
~ F49 is divided into 36 pieces. Then, each frame F1
The images of 1 to F49 are converted into the image signals of the above system, and the obtained image signals of even lines and odd lines of each frame are
As shown in FIG. 12A, a fixed number is repeatedly recorded on the video tape. Also, the synchronization signal is recorded in the same manner as above.

On the other hand, in parallel with the recording operation of the image signal,
The bedder information and the additional information are recorded on the audio track AT of the video tape. One piece of header information is always recorded corresponding to each frame of the image signal. This header information, as shown in FIG.
It is composed of information such as date, page, X address, Y address, and CRC code, and the information contents thereof are the same as in the case of FIG. 6B.

When the operator inputs the additional information, the additional information is recorded corresponding to the whole image signal of one page by using the empty area after recording the header information.

When the recording of the information of one page is completed and there is information of the next page, a gap is formed for a certain section and then the information of the next page is similarly recorded. In this way, the received image is recorded on the video tape (the process 5
07), the reception process is ended. If the received image is not saved (N in process 505), the reception process is ended as it is.

Next, the reproducing operation of the recorded image will be described.

When the operator reproduces the recorded image,
As shown in FIG. 13, the video tape is mounted on the video tape deck 12 and the reproducing operation is started (process 60).
1). As a result, the image of each frame recorded on the video tape is sequentially displayed (process 602).

FIG. 14 shows the reproduction operation of the frame image at this time. That is, when the reproduction operation is started, the video tape deck 12 reads the header information and the additional information from the audio track AT and the image signal of each frame from the video track VT (process 701). The image signal is displayed on the screen display unit 11.

The image processing apparatus sets the read image signal to 1
Each frame is sequentially converted into image information of a digital signal (process 702). The image information obtained by this conversion corresponds to each of the frames F11 to F49 shown in FIG. These pieces of image information include the X address and Y of the header information.
The page memory 7 is sequentially stored in a predetermined position according to the address (process 703). The image of the portion in which the image information is stored is displayed on the tablet image input / output unit 6.

Such an operation is repeatedly executed until the video tape is stopped (step 704, N in step 704).
To process 701).

As a result, the images are sequentially assembled in the page memory 7 frame by frame and the image of one page is restored. When the image has a plurality of pages, the same operation is executed one page at a time. Then, when the video tape deck 12 is stopped (Y in step 704), the above operation is ended.

The operator confirms the displayed image, additional information, etc., and determines whether or not the image is a desired image (see FIG. 13).
Process 603). If the image is not the desired image (N in step 603), the operation is started again after fast-forwarding or rewinding the videotape (step 604) (step 601).
What).

In this way, when one desired image has been read to the end (Y in step 603), the reproduction operation is stopped (step 605). Here, if necessary, a page to be displayed is changed or a handwritten image is additionally written as in the above case (process 606).

This image processing apparatus has a function of transmitting the image thus reproduced to another facsimile apparatus. When the image is thus transmitted (Y in process 607), the operator makes a call to the other party using the wireless telephone device 1 (process 608), and activates the transmission operation on the operation display unit 13 (process 609).

As a result, the image processing apparatus instructs the destination facsimile apparatus to follow the predetermined transmission control procedure.
The image information stored in the page memory 7 is transmitted (process 610). If the image is not transmitted (process 60)
7 N), after the image display, the operation is finished as it is.

As described above, in this embodiment, when the image of each frame is recorded on the image track of the video tape,
Position information indicating the frame position is recorded as header information on the audio track.

In the above-described embodiment, the header information is embedded in the image signal, so it is necessary to separate and extract the header information from the image signal during image reproduction. Since the information is recorded on the audio track as independent information, the header information can be read easily and surely. This makes it possible to more reliably restore the original image of one page from the recorded frame images.

In addition to the above-mentioned header information, information such as image contents arbitrarily input by the operator is recorded on the audio track as additional information, and when the image is read, the additional information is also read and displayed. I have to. As a result, when the recorded image on the video tape is reproduced, the content of the image being reproduced can be immediately determined, and the recorded image desired for the image can be quickly read.

Next, a third embodiment of the present invention will be described.

In this embodiment, as shown in FIG. 15, a character / speech conversion unit 17 and an additional information output unit 18 are arranged on the apparatus configuration of FIG. The character / speech converter 17
The character information is converted into a spoken speech signal character by character. The additional information output unit 18 outputs the reproduced audio signal from the speaker.

With this configuration, when recording an image on a video tape, the above-mentioned header information is added to D /
The A converter 16 converts the analog signal into an analog signal and records it on the audio track of the video tape. Also, along with this, route B
Then, the additional information input on the operation display unit 14 is converted into a sound signal by the character / speech conversion unit 17 and similarly recorded on the sound track.

On the other hand, when reproducing the recorded image, the header information is reproduced on the path A, while the audio signal which is the additional information is output from the speaker on the path C.

As described above, by recording the additional information which is the character information as the voice signal of the spoken word and reproducing it as the voice, the operator can hear the additional information while watching the reproduced image. It becomes easy to understand.

Next, a fourth embodiment of the present invention will be described.

In the present embodiment, an additional information input / output unit 19 is arranged on the apparatus structure of FIG. 9 as shown in FIG. The additional information input / output unit 19 inputs a voice uttered by an operator and outputs a reproduced voice signal from a speaker.

With this structure, when recording an image on a video tape, the header information is recorded on the audio track of the video tape in the same manner as in the above-described embodiment along path A in the figure. Further, during the recording operation, the operator inputs a desired voice message as additional information from the microphone. Then, the input voice message is recorded in the voice track.

On the other hand, when the recorded image is reproduced, the header information is reproduced on the route A, while the audio signal which is the additional information is outputted from the speaker on the route B.

As described above, by inputting / outputting the additional information by the voice signal, the operator can eliminate the trouble of inputting the character information with the keyboard or the like.

By the way, when an audio signal is recorded on the video tape deck 12, the recording system includes an analog recording system and a digital recording system. The video tape deck 12 of each of the above-mentioned embodiments can be arbitrarily used regardless of such a recording system. However, when the analog recording type video tape deck 12 is used, the circuit configuration of the video tape deck 12 is simple and inexpensive, but the reliability of recorded information is low. On the other hand, when the digital recording type is used, the circuit configuration is slightly complicated and expensive, but the reliability of the recorded information is high.

Now, a fifth embodiment of the present invention using a digital recording type video tape deck will be described.

In this embodiment, the video tape deck 12 is used.
As shown in FIG. 17, the A / D conversion circuit 12a and the digital signal recording / recording circuit are circuits for recording an audio signal.
And a reproduction circuit 12b.

The A / D conversion circuit 12a converts an input audio signal into a digital signal and inversely converts the digital signal read by the digital signal recording / reproducing circuit 12b into an original audio signal. Digital signal recording /
The reproduction circuit 12b records the digital signal output from the A / D conversion circuit 12a on an audio track of a video tape by a predetermined digital recording method, and reproduces the recorded digital signal.

In this embodiment, the A / D conversion circuit 12a and the digital signal recording / reproducing circuit 12b in the video tape deck 12 are separated from each other, and the digital signal recording / reproducing circuit 12b and the system control section 15 are separated from each other. Connect directly.

With this configuration, when an image is recorded on a video tape, the system control unit 15 digitally records the header information and the additional information in the digital signal recording / reproducing circuit 1.
2b, and each information is recorded on the audio track by the digital signal recording / reproducing circuit 12b.

When reproducing a recorded image, the digital signal recording / reproducing circuit 12b reads the recording information and directly outputs it to the system control section 15 side.

As described above, by recording the audio signal by the digital recording method, the data error at the time of recording / reproducing the information is reduced and the reliability is improved. Also in this case,
By inputting the header information and the additional information to the video tape deck 12 as a digital signal, D in FIG.
