FIG. 2 is a schematic perspective view showing an example of the main parts of the image input/output device in FIG. 1, and FIG. 3 is a cross-sectional view taken along the line A-A. This figure shows an example in which a recording head and a reading head are mounted on a carrier, assembled integrally into a type serial printer device.

In the figure, 50 is a platen roller of the printer;
The recording paper or original to be read 52 is placed on the platen roller 50.
is wrapped. Reference numeral 54 denotes a paper pressing roller for pressing the recording paper or original 52 against the platen roller 50.

Further, f is the conveyance direction of the recording paper or original document 52.

On the other hand, 56 is a carry l guide fixed to the printer body parallel to the platen roller 50, and the guide 56
The carrier 58 is moved back and forth along the carrier guide 56 by suitable drive means. The carrier 58 is provided with a thermal head 60 and an ink ribbon cassette 62 at a position facing the platen roller 50. The ink ribbon 84 in this set 82 passes between the thermal head 60 and the platen roller 50 and is wound.

Further, an image reading head 66 of an image reading device is placed on the carrier 58. The read head 66, as shown in FIG. 3, has a convergent light transmitter array 76, a read sensor 78 that performs photoelectric conversion, and a light mixing source such as an LED (not shown). The reading sensor 78 has, for example, a group of 24 pixels arranged in the vertical direction. Further, an indicator 7 indicating the position of the reading sensor 78 is provided on the surface of the reading head 66.

In this way, since the upper end of the reading sensor 78 and the position of the index 72 do not physically match, the position a on the document image corresponding to the position of the index 72, which the operator uses as a guide, when reading is read by the reading sensor. This is different from the position on the image.

Therefore, in this example, when image reading is interrupted and reading is performed from another position, reading starts when the index 72 on the recording head 66 is positioned at the upper end a of the line related to the reading after the interruption. Sometimes, position correction processing is performed so that the positioned a matches the position.

Specifically, when reading images continuously, a c-b N line feed is performed every 24 dots, and when there is an interrupt command, a c-b N line feed is performed so that the L end of the next line is located at a. Performs a line feed by the amount of a. When the upper end of another reading line is positioned at position a and a reading start command is given, the document is rewound by an amount ba in the direction opposite to the f direction.

When the device shown in the second figure according to this example is used as a word processor printer, a recording paper 52 is wound around a platen roller 50, a carrier 58 is moved along a guide 56, and an ink ribbon 64 is run. The thermal head 60 is operated while On the other hand, when used as an image reading device, the document 52 to be read is placed on the platen roller 501-, the document to be read is irradiated with a light source, and the convergent light transmitting body array 76 is moved while the carrier 58 is moved along the guide 56. The image of the document surface is formed on the reading sensor 78.

Next, aspects of the image editing process according to the present invention will be explained using FIGS. 4 to 7.

FIG. 4 schematically shows an example of the image editing processing procedure performed by the apparatus of the present invention. In this processing procedure, for example, an input key for executing image editing can be provided on the keyboard 8, and the process can be shifted in response to the second operation.

To start the process, first, in steps S2 and S4, the read mode flag RMODE is set to 0.
” and the cursor shape flag GFLAG are turned on. By turning on this cursor flag CFLAG, a dot point cursor is selected as the cursor, making it easy to specify a range in the following processing.

In step S6, manual input of the key is waited, and if the input key is determined to be a range specification key in step S8 or a reading mode selection key in step S10, a reading start command is issued in step S12. If it is determined to be a key, or if it is determined to be an end key,
Range specification processing (step SH), reading mode, that is, logical operation type determination processing during editing (
Step SM), reading processing (SR), and other processing such as saving the edited image to a magnetic disk (Step S
After performing step O), the process returns to step S6. On the other hand, if the key entered is not one of these keys,
In step 51B, the cursor shape flag CFLAG is turned off and the cursor is set as a character-by-character moving cursor, and then, for example, a character processing mode is entered.

The processing contents in steps SH, SN, and SR according to this example will be described below.

In step SH, for example, an area corresponding to the image area of the image memory GBUF is displayed on the display screen of the display device 20, and the operator is prompted to specify the reading range of the document image and the editing range to the image area. The operator may input the following instructions in response to this.

First, to input the reading range instruction for the original image, as shown in FIG. Point A and point B of area GA of display screen 2 corresponding to range IA on 52 are indicated. Accordingly, the address on the image memory GBUF corresponding to point A, the number of read dots in the horizontal direction HY, and the number of read dots in the vertical direction IT are set to the area HAI on the memory 6, respectively.
Stored in IR, HYSIZE and HTSIZE. In conjunction with this instruction, manually move the carrier 58 and platen 50 to move the upper left vertex of range IA to the third position.
Match position a in the figure. In this case, the operator can perform the range specification process while visually confirming the process.

In addition, when inputting an instruction for the transfer range of the read image to the image memory GBUF, as shown in FIG.
When the UF image area is displayed, the operator uses a cursor to point to point A' and point B' in area GA' of display screen 1-1, which corresponds to range RA' on document 52 that the operator desires to read. Accordingly, the address of the image memory GBUFJ corresponding to the point A', the transfer range GA'
The number of dots in the horizontal direction HY', the number of dots in the vertical direction HT'
, respectively, memory 6” second area HADR1HYS
IZE and) ITSIZH.

After setting these values, end the range specification processing procedure SH,
The process returns to step S6 and waits for the next key personnel.

FIG. 5 shows an example of specific processing contents of the reading mode determination processing procedure (step SM). Here, first, in step SN2, a count-up process for l'1M0DE is performed. Next, in step SM4, calculation processing (in this example, 2
) corresponding to the maximum value in RMODE (“1” in this example)
It is determined whether the RMOI exceeds the
The value of IE is set to 0''. If a negative determination is made in step SM4, or after the processing in step SMB, for example, the arithmetic processing name corresponding to that value is displayed, and the reading mode determination processing is terminated. Then, the process returns to step S6.

Next, FIG. 6 shows an example of specific processing contents in the reading processing procedure (step SR). First, step SR
In step 2, the image information already in the image memory area GBUF is developed into the storage image memory area PCBUF and storage processing is performed. This makes it possible to prevent destruction of existing image information even when the compositing process is canceled.

Next, in step SR[i, after turning on the start correction flag, in step SR6, the image information in the area GBUF is appropriately reduced, transferred to the buffer DBUF, and inverted on the display screen of the display device 20. to be displayed.

In step SR8, key human power is determined. If the input key is determined to be the interrupt key in step 5RIO, then in step 5R12, as described above with reference to FIG. At step 5R14, the start correction flag is turned on, and at step 5R1B, key human power is awaited.

If a negative determination is made in step 5RIO, or if there is a key input in step 5R113, it is determined in step 5R20 whether or not the input key is a stop key for canceling image reading. If it is determined that the back is 1 here, in step 5R22 the area RGBUF
By expanding the image information stored in , into the area GBUF, if the compositing process has been performed before the manual operation of the stop key, the compositing process will be invalidated, and if the image information has already been expanded to the area GBUF before the compositing process. Image information becomes valid.

If a negative determination is made in step 5R20, it is determined in step 5R24 whether or not the input key is an end key. In case of negative judgment, step SRD (7th
After executing the reading operation processing procedure shown in Figure), step 5R
2B, the image information read and stored in the area RBUF and the corresponding image information on the area GBUF, that is, the editing range specified in step SH, based on the logical operation content selected in advance by the processing in step SM. Performs dot-by-dot compositing processing with the image information within. Then,
In step 5R30, the read portion of the image memory area GBUF, that is, the image information corresponding to the number of horizontal dots subjected to arithmetic processing, is appropriately reduced and transferred to the buffer DBUF for display. At this time, on the display screen, the portions that have been subjected to the composition processing are successively converted from the judgment display to the normal display and displayed, so that the operator can recognize the progress of the processing at a glance.

Next, in step 5R32, it is determined whether or not the number of vertical dots in the reading range specified in step SH has been read. This determination is made after completing the calculation for the number of dots in the lateral force direction (step 5R28).
This can be done by subtracting the number of vertical dots per unit (24 in this example, corresponding to the number of arrayed pixels) from ZE, and detecting whether the value of area HTSIZE is no longer positive. If the determination in step SR32 is negative, step S
Returning to R8, reading and arithmetic processing are performed for the next number of vertical dots in one unit. On the other hand, step 5
If it is determined that tsr is constant in R32, and in step 5
If an affirmative determination is made in R24, the reading processing procedure S
R is finished, and the process returns to step S6 in FIG.

FIG. 7 shows an example of the processing contents in the read operation processing procedure SRD of FIG. 6. First, in step 5RD2, the state of the start correction flag RFLAG is determined. Here, if the determination is negative, the process immediately proceeds to step 5RDlli, and if the determination is positive, the carrier rewinds the document 52 by an amount b-a in the direction opposite to the f direction at the time of starting reading, as described above with reference to FIG. After performing the position correction process, the process advances to step 5RDB.

In step 5RDB, the start correction flag RFLA
G is turned off, and then in step 5RD8, the carrier 58 reads the number of dots in the horizontal direction from the set position in the specified reading area, and stores the read image information in the area RBUF.

Next, in steps SRD10 and 5RDI2, a return process of the carrier 58 and a line feed process of transporting the document 52 in the f direction by the number of vertical dots per unit are performed, and the reading operation process SRD is completed and the process returns to step 5R28 in FIG. Transition.

As described above, in the image processing apparatus according to the present example, first, through the range specification process (step SH), a range on the document 52 that is desired to be read is specified, and an editing range for the image area of that range is specified. This makes it easier for the operator to do the following. The starting position of the designated reading range in connection with the reading range designation is positioned to match the index 72, and the position is corrected to an appropriate position corresponding to the arrangement position of the sensor 78 when reading starts. Therefore, the operator can accurately specify the reading range using the index 72 as a guide when starting the operation for composition processing or when reading is interrupted.

Further, since the interrupt key for interrupting image reading can be accepted by the procedure of step 5RIO, and the reading range can be changed by the procedure of step SH, there are multiple ranges in the document 52-h that are desired to be read. In this case, it becomes possible to appropriately read those multiple reading ranges in a series of processing flows.

For example, as shown in FIG. 10, if there are three parts At, Bl and C1 in the original 52'' which are desired to be read, the range specification, reading and area GBU of part A1 are performed.
After editing to "F"2, give an interrupt command, specify the range of part B1, read, and edit on area GBUF.Furthermore, give an interrupt specification, specify the range of part C1, read, and edit on area GBUF. It becomes easier to do what you want to do. It goes without saying that the processing order for the plurality of parts can be determined as desired by the operator.

Further, as shown in FIG. 11, steps SR6 and SR5
Through the processing of R30, the original 5 is displayed on the display screen of the display device 20 in association with the inverted image on the editing area GBUF.
Since the image information is sequentially read from the reading range above 2, subjected to arithmetic processing, and displayed, the operator can see the progress of the processing at a glance. This results in
The operator can read the image on the original document 52 until the required part of the image being edited is reached while checking on the screen.

Furthermore, in the process of step SR2, the image already in the area GBUF is saved before the editing process, so
Even if the editing process is canceled in step 5R20, the original image will not be destroyed, and the image saved by the process in step 5R22 will be expanded to the area GBUF again, so the operator can quickly You can immediately start a new editing process.

For example, as shown in FIG. 12, the image stored in area GBUF is first saved in area RGBUF.

Next, when the image in area GBUF and the image read from the document 52 are combined while performing an OR operation up to the position of The saved image will be overridden in area GBUF.

In addition, according to this example, the image to be edited is sequentially read from the original and image synthesis processing is performed based on the calculation details given in advance by the operator, so the operator can It is possible to provide flexibility in the compositing process when performing the editing process while repeating the process.

In the non-embodiments, an image processing apparatus having an image reading head mounted on a word processor has been described, but the present invention can of course be applied to any type of apparatus equipped with an image reading means. Furthermore, in this example, an image processing device is described that includes an image reading head that is mounted on a carrier and is moved in the scanning direction with respect to the document surface. It goes without saying that it may be anything.

(Effects) As explained above, according to the present invention, there is an area corresponding to the document surface and the image area, and by specifying the coordinates of the area L, the document can be adjusted. By providing a means for easily specifying the reading range of the document image 1-, the area desired to be read in the document image 1- can be appropriately developed into the image area-1- according to the specification, thereby improving processing efficiency during editing processing. This has the effect of realizing an image processing device with significantly higher performance.
