Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to image data transmission that edits image data, transfers the image data to a receiving system on the other side, and outputs the image data to a printer on the receiving side system. It is related to the device.

[Conventional technology]

Traditionally, facsimile machines used in office settings have been a typical image data transmitting device, which usually scans a black and white original, then encodes the data for all the scanned originals and sends it to other receiving devices. Generally, data is transferred, and the receiving side decompresses and outputs the sent data as is.

[Problem to be solved by the invention] In the conventional example described above, the sending system does not have an editing function, so when combining and transmitting multiple manuscripts, the operator has to create a composite manuscript in advance. , there was a drawback that unnecessary parts were also transmitted.

In addition, if the output paper size is constant on the receiving system regardless of the position and size of the transferred image data, if the transferred image size is small, there will be a large amount of blank space. There were drawbacks.

[Means for Solving the Problems (and Effects)] According to the present invention, by providing an image display device and a pointing device to the sending side system so that editing work can be performed interactively, it is possible to edit from a document read by a scanner. It makes it possible to cut out and output the part that you want to transfer and specify its position, it allows you to perform image compositing interactively, and it also makes it possible to transfer the editing results to the other party's system.

Furthermore, it is also possible for the receiving side system to select and output an output paper based on the size of the image data transferred from the transmitting side.

〔Example〕

In the first embodiment, a case will be considered in which the sending/receiving system on the sending side has only one memory for storing image data.

FIG. 1 shows a system configuration diagram in this embodiment. Reference numeral 1 in the figure is the main control unit that controls the entire system, which stores the procedures shown in Figure 4 and controls each part described below.
Control as shown in the figure. A memory 2 stores image data read from the scanner section 6 through the data conversion section 5 and image data sent from another system through the communication control section 4. A printer section 7 outputs image data from the memory 2 through the data conversion section 5.

Reference numeral 3 denotes an operation section, which has a display section for displaying image data read from the scanner section 6 or image data sent from another system, and for displaying image data stored in the memory section 3. It is composed of It also includes a pointing device control unit for inputting coordinates in image data, and is used when specifying a transfer image area in displayed image data.

A detailed block diagram of this operating section 3 is shown in FIG.

21 in Figure 2. Reference numeral 22 denotes a frame memory that stores image data to be displayed on the display 25. The image data is sent from the frame memories 21 and 22 to a synthesizer 23 to create a two-sided composite image, and this data is sent to the D/A. The converter 24 converts the data into display data and displays it on the display 25.

28 is a mouse as a pointing device, and 27 is a control unit thereof. 26 is the control register of the synthesizer 23
This is a register for controlling. 20 is a system bus for connecting these devices, and is connected to the main control section l shown in FIG. The operation of the editing work will be explained below according to the flowchart shown in FIG. first,
As preprocessing, a transmission request command shown in FIG. 5 is issued by the pointing device, and sent to the receiving system and waits for an answer.

After that, frame memory 2 is cleared. Then, in step 2, the scanner unit 6 is activated to read the original. The image data outputted from the scanner section 6 is converted through the data conversion section 5 into data of 8 bits each for RGB for display, for example, and stored in the memory 2.

The processing of the data converter 5 may be omitted depending on the case. After reading one document, the document is transferred from the memory 2 to the frame memory 1 in the operation section 3. At this time, since the number of pixels for reading is larger than the resolution of the display for fishing on a boat, the data will be transferred according to a certain reduction ratio. This allows the entire area of the read image data to be viewed at once. By setting the control register 26 for the synthesizer 23 to display only the frame memory 1, the currently read image is displayed on the display 25.

Next, in step S4, an area to be transferred is specified from among the read image data using a pointing device.

The designated area is the area surrounded by 30 dotted lines shown in FIG. 3a. If this area is acceptable, move on to specifying the transfer destination position.

If the area is good (if not, you may add l'-UNDOJ processing etc.) When specifying the transfer destination position, first set the frame memory l and control register so that only the cut area is displayed. 26 is rewritten and stored in frame memory 1.Scroll the position 30 to position 31 in Figure 3b using the pointing device.Then, move the area other than 31 so that frame memory 2 is displayed. Thereafter, by specifying with the pointing device that the image 31 is to be moved to a desired position by the operator, for example, the position shown in FIG.
The frame memory 1 is scrolled and displayed according to the displacement of the pointing device up to position 2. These operations can be controlled interactively by displaying icons on the display 25 and selecting them using the mouse or in some cases, while looking at the display 25.

Once the transfer destination position is determined, decide whether to load the next image or not. If you want to load another image, send a data transfer request command to the receiving side to transfer the area specified this time to the specified position. Transfer to the system and wait for an answer from the receiving side. Thereafter, in step S8, the actual cropped image data is transferred. When transferring this image data, the main control unit converts it into an address on the actual memory corresponding to the area specified on the display and transfers it to memory 2 in Figure 1.
Transfer the image data stored in the . At the same time as this transfer, the image data of the designated area in the image data for display stored in the frame memory 1 is transferred to the corresponding position in the frame memory 2. This creates an image on the frame memory 2 to be output on the receiving side. When a plurality of documents are combined and transferred, the operations from reading to image data transfer can be repeated. 3rd c
The figure shows a case where three manuscripts are combined.

Finally, the transmission work is completed by transferring a termination command to terminate the transmission. FIG. 5 shows a command and data transfer sequence between the transmitting and receiving devices in this embodiment. Sending-side operations A to D indicate operations performed by an operator on the sending-side device from reading a document to specifying a transfer destination position, respectively.

The receiving system executes the command transferred from the transmitting system and writes the image data to the corresponding location in the memory of the receiving system so that the image data is output to the specified location.

When the last end command is received, the image data received so far is sent from the memory to the printer section and output.

[Other Examples]

In the second embodiment, a case will be considered in which there are memories for storing image data for several images. In this case, only the parts different from the first embodiment will be explained. The process from the operator instructing to perform editing processing to reading the original and specifying the transfer destination position is the same as in the first embodiment. In the first embodiment, the image data is transferred to the receiving system once the transfer destination position is determined, but in this embodiment, the image data is transferred to the receiving system when the transmitting system has memory for several images. Therefore, it is sufficient to sequentially save the data to the second and subsequent memories. Similar to the first embodiment,
The image data of the specified area in the image data for display stored in the frame memory 1 is transferred to the frame memory 2.
Transfer to the appropriate location. This creates an image on the frame memory 2 to be output on the receiving side. Then, when the operator selects the final termination, the image data that has been saved so far is sent in the specified order by the data transfer request command, and the area size information and output position information are sent, and then the actual image data is transferred. The process can be repeated by transferring the number of bones synthesized by the operator. And finally, just send the exit command. The sequence of commands and image data transfer between the transmitting and receiving systems at this time is shown in FIG.

In this embodiment, rUNDOJ processing is possible for all combined images because even after they have been determined, the transmitting system retains them in the memory in the form of image data.

Further, the transfer sequence of commands and image data between the transmitting and receiving systems is not limited to those shown in FIGS. 5 and 6.

Furthermore, the number of frame memories that can be combined using the display device of the operation section is not limited to two; if two or more images can be combined, the determined image data for display cannot be transferred to the frame memory 2. Instead, it is sufficient to directly control the images in each frame memory to be combined and displayed.

[Receiving side control]

As shown in the first and second embodiments, the control of the output paper in the receiving device when the image size transferred from the sending system is different from the original size will be described.

To simplify the explanation, it is assumed that the printer connected to this apparatus can select two types of output paper: A4 and A3. Also, consider a case where the sending side specifies an area to be transferred from an A3 document and transfers it to the receiving side. This explanation will be given using FIG. 7. First, in the sending system, the operator specifies a rectangular area 72 surrounded by a dotted line in the A3 original 70 as the image area to be transferred, and further specifies the output position on the output paper as an area 73 surrounded by a dotted line 71-a. Consider the case where .

The receiving system that receives this image data determines whether the area 73 can be output on A4 paper.

For example, when processing an A3 size document with a scanner printer that has a resolution of 16 dots/mm, the A3 size is 4752 * 6720 pixels, and the A4 size is 4752 * 3360 pixels, so 73 output addresses and transfer areas are required. From size to A4 size (4752*
The main control unit determines whether it falls within the area of 3360 pixels),
A control signal for selecting an A4 size output sheet is output to the printer section, and the output is output as an image of the upper half area of 71-a. When the data is transferred to area 74 on 71-b, control is performed so that A3 size output paper is selected. 71
As shown in -C, when compositing multiple images, it is necessary to determine whether the entire image to be output is A3 size or A4 size. In this case as well, each area, 75.76, is transferred from the sending system, so
The paper may be selected from the output position address and area size of each area, and control may be performed so that the largest size among the papers is set as the output paper size.

As explained above, by determining the output paper size from the transferred image size and position, it is possible to output the image onto the paper with minimal extra margins.

Furthermore, in this embodiment, an example has been described in which the original size on the sending side is A3 and the receiving system selects A3/A4 paper, but the invention is not limited to this. For example, if the original size on the sending side is A4 size, It is also possible to combine a plurality of sheets and output them on A3 size paper.

Further, in this embodiment, two types of paper, A4/A3, are selected, but the present invention is not limited to this, and it can be easily inferred that several types of paper can be selected.

〔Effect of the invention〕

As explained above, in the image data transmitting/receiving device,
By providing a display and pointing device for display, it is possible to interactively create an output image directly on the sending system by specifying the transfer area and output position on the sending system. can.

Furthermore, by having a memory for storing several images in the transmitting system, editing work can be performed more easily, and the time dedicated to the line between the transmitting and receiving systems can be shortened.

Furthermore, the receiving system selects the optimal paper size based on the size and output position of the image data transferred from the sending system, and outputs an output image with minimal extra margins. can be obtained.
