Abstract

PURPOSE:To attain image input operation easily and quickly by providing a moving means for moving an image displayed by plural scannings in an optional direction in the unit of blocks. CONSTITUTION:A medium to be read is scanned by a scanner 1 having a prescribed read width while being divided into plural numbers and an overlapped part exists. In this case, the read data scanned once is stored in a page memory section PAE as one-block image data. When the image input is finished, the image data is displayed on a display section 21 and the operator uses a mouse 22 and moves the overlapped part as a block while observing the displayed screen to eliminate overlapped scanned inputs and form a correct drawing.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a method for scanning a medium to be read in multiple times with a scanner having a predetermined scanning width. The present invention relates to an image input method used in an image input mechanism that inputs an image as an input object.

[Technical background of the invention and its problems]

2. Description of the Related Art Conventionally, when an image such as a character or a figure drawn on a sheet of paper, a plate-shaped member, etc. is inputted using a scanner, the image is sequentially inputted by performing partial scanning a plurality of times. At this time, the scanning position accuracy of the scanner in each partial scan is low, and even if a ruler or a dedicated scanning machine is used, vertical and horizontal positional deviations occur due to each scan. Therefore, a portion of the image input data for each scan overlaps with the data read in the previous scan, or vice versa, a gap occurs, and furthermore, a mutual positional shift occurs. A specific example thereof will be explained using FIG. 1. When the figure on the input paper 3 shown in the figure (-) is read by a scanner and outputted on the display screen, the result will be as shown in the figure (b).

Here, in the scan of d, input is started from the left side compared to the other scans, so the image data is shifted to the right.

Furthermore, in the scanning of d4 and d, since dl was scanned so as to overlap the lower part of d4, a portion of the data is inputted overlappingly.

Conventionally, when inputting an image by partial scanning with a scanner, the scan position accuracy is poor even if it takes a lot of time to input carefully. The drawback was that the image quality could not be obtained.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and in a scanner that inputs an image on a medium to be read by multiple partial scans, it is possible to scan the entire surface of the medium to be read without accurately scanning the entire surface of the medium. To provide an image input method that can easily input highly accurate image data by a simple and quick image input operation of duplicating images of a partial area along the .

[Summary of the Invention] The present invention provides an image that inputs an image to be input drawn on a medium to be read by scanning the medium in multiple times with a scanner having a predetermined scanning width of 9. In the input mechanism, the read data obtained when the medium to be read is continuously scanned once in a fixed direction by the scanner is managed as one block of image input data,
The system is equipped with a means for displaying the image, and a moving means such as a mouse for moving the displayed image block by block in any direction, thereby accurately scanning the entire surface of the medium to be read. without inputting
Image input operations can be performed easily and quickly because a part of the image input in the previous scan can be input redundantly in the next scan, and then each block can be moved to align each block. Highly accurate images can be input.

Here, the operation of one embodiment will be described with reference to the drawings.

The present invention scans the medium to be read using a hand scanner having a predetermined reading width in multiple times, overlapping each other with the previous scan, thereby creating an image to be input on the medium to be read. By inputting the image data, managing and editing the image data of each scan as a unit (one data block), it is possible to input high-quality (beautiful) images using the scanner.

First, when explaining the specific operation, an overview will be given.

The present invention provides an image input method in which an image to be input drawn on a medium to be read is input by scanning the medium to be read in multiple times with a scanner having a predetermined reading width. The read data obtained when the medium to be read is scanned once in a fixed direction by the scanner is stored as one block of image data in a page memory unit (PAE) so that it can be managed (for example, each data For each block, position information of the same block,
Information such as the length in the direction, the length in the Y direction, and the memory address containing the image data of the block is stored in a table and managed). When each data block is input to the scanner, it is assumed that the data block is scanned with an overlapped portion of the data input in the previous scan. As another means, when the above-mentioned scanner scans once in a certain direction, the -read data is 1
Datab0. As image input data, development position information indicating the position at the time of pattern development (for example, when displayed on a CRT display section) is added to each data block, and
It is also possible to take a predetermined response and store it. When the image input is completed in this way, these image data are displayed on the CRT display section, and while looking at the screen on which the oirator is displayed, the data processor is inputted for each input using a pointing device (e.g., a mouse). The overlapping part is moved sequentially, data block by block is moved, and the overlapping part of the input of each scan is eliminated.
Create the correct screen. On the screen, if the lower data block overlaps the upper data block, the image data for that part will be displayed in the overlapping part. On the other hand, an operator can easily use a pointing device to obtain the correct screen while looking at the screen. With such an image input means, it is possible to improve the image quality of the image data at both ends of each scan of the image data input by the hand scanner.

Here, the specific operation of one embodiment will be explained with reference to the drawings.

FIG. 1(,) is a diagram showing an example of image input for explaining the operation of one embodiment. Here, a state in which the hand scanner 1 is currently scanned from left to right is shown. That is, "A1 figure input" on paper 3 has been input. The sensor section of the hand scanner 1 has a width of W, and image data (data block corresponding to 31 in FIG. 3) of [width W] x [1 scan] can be obtained at one time by scanning twice. After completing this one scan, the ruler 2 is translated downward by a width W (in this case, the width W-α). Then, the hand scanner 1 is scanned once from left to right in the same manner as described above. Here, the image input means for storing the scanned image data on the memory is operated by operating an image input start switch 5 provided on the image scanner 1, which is recognized by the microcomputer 11.
There is a system in which the image is input (read) by encoder output pulses generated at fixed distances as the internal roller R rotates as the hand scanner 1 moves, and there is no switch 5 mentioned above (even if there is, it is used for a different purpose). There is a method in which the microcomputer 11 is interrupted by the occurrence of an encoder error due to the movement of the hand scanner 1, and the microcomputer reads the image data, but any method may be used here.

Next, the operation of one embodiment will be described with reference to FIGS. 1 to 4. Now, as described above, the hand scanner 1 is scanned once from left to right as shown in FIG.

The input image data for one data program is stored as image data 31 in the page memory section (PAE) K in the internal memory 12 under the control of the microcomputer 11 as shown in FIG. At the same time, if the start address A1 where the image data 31 is stored is the ID=(1) table part of the microcomputer l1ld:,9 management table 30, set the memory address of the management table 30=A, Y length (W) of the same table
The position of is set to a value according to a parameter value previously specified by the key operator 23. For example, when the deviation of the start position of each scan at the left end of the hand scanner 1 is set as a parameter of ±100 dots, the positions are set as X=X□=100 and Y=Y1=Q.

That is, X and Y are the CRT of the CRT display section 21 in FIG.
Assuming that x=o and y=o at the upper left of the display section 21, this means the position of point Q, which is 100 dots to the right in the X direction. As shown in FIG. 1(a), when the text 6 is input, the movement of the hand scanner 1 is stopped at the right edge of the paper 3, and the image input start switch 5 is released, the input of the data block d1 is completed and the microcomputer 11 is The count value of the number of input data bits, X length = 1. The dot value is calculated and stored in the management table 30 at X length=11. Further, the microcomputer 11 stores the final byte address +1 address of the area where the image data 31 is to be stored = A in the table of ID (2) of the management table 3°. Here, the data input width (W) of hand scanner 1 is 24 dots (=W
), by moving 1 dot in the X direction, 2
4 dots 21) (= 3 bytes) are read by the microcomputer 11, and under the control of the same microcomputer 11, the image data 31 is stored one byte at a time starting from the AI address. Three bytes are stored sequentially. At this time, the memory 12
Bytes (8 pits)) + 111, the third
Image data 31, 32 in the figure. . . 36, but it is expressed here as shown in Fig. 3 to make the explanation easier to understand. Next, when inputting data block d, the microcomputer 11 stores X, = 100, Y, = 24°Y length W = 24 in the table of ID (2), and the input of data block d is When completed, the same block d! Number of bytes ÷ 3 = X length; 1. Store as value. Similarly, sequentially, X, = 100, X4~X, = 1
00, Y, =48, Y, =72°Y, =96
, Y, = 120, Y length W; 24, etc. are set. The value of the X length changes because the input length in the X direction for each scan is different. Also, the memory address value changes accordingly. Image data 31 during scan input. :12 inputs the image data 30 and 31 from the hand scanner and partially (α
(only bits) will be entered twice.

In this way, the paper 3 shown in Figure 1 (,) is scanned six times, and the page memory section (
After storing the data in the page memory section (PAE), the operator then instructs the key date 23 to complete the input and instructs the CRT display section 21 to display the data in the page memory section (PAE). The microcomputer 11 is a management table 30
According to the data, image data (31, 32,...36) is stored in the bitmap memory of the CRT controller 15.
move. As a result, the contents (images) of the bitmap memory are sequentially displayed on the CRT display section 21, as shown in FIG.
It will be displayed as shown in b). At this time, instead of sequentially storing the contents of addresses (A1) to (A, +3 x 1.) of the page memory section (PAE) in the bitmap memory, management is performed for each of the four data blocks d□ to d. Needless to say, the address of the bitmap memory is calculated from the table with ID=0 in the table 30 and stored.

Next, while looking at the screen of the CRT display unit 21, the operator uses the mouse 221/C to correct unnatural parts of the displayed image. This modification can be done by using the mouse 22 on the CRT.
This is done by moving the cursor on the screen of the display section 2 and aligning the positions with each other. That is, the microcomputer 1 of the block 22f'C recognizes the data clocks d□ to d6 in advance, moves the cursor to the block to be corrected (dS in this case), and
When the mouse 22 is moved to the left while holding down a predetermined switch on the mouse 22, the microcomputer 11 processes to shift the entire data block d to the left. The microcomputer 11 is operated by an operator C.
When it is detected by the movement of the mouse 22 that data block d is to be moved on the RT display unit 21, X, , Y3 in the table with ID (3) are corrected, and the corrected data is stored in the bitmap memory in the CRT controller 15. The image data 31 is moved to memory address A and stored sequentially. When the storage of the image data 31 is finished, zero is stored in the previously stored portion and the unshaped portion this time, and the previous image is erased. As described above, data block d has been moved slightly to the left on the CRT display section 21. The operator displays the CRT display section 2.
If the user looks at the screen No. 1 and determines that the corrected drawing is still not accurate, the user moves the mouse 22 and instructs it to move further to the left. As a result, the microcomputer 11 moves the booters o and ri to the left in the same manner as described above. and j
When the data block d3 moves to the left of the β dot as shown in the image data 33 in the diagram llfJ, the operator stops moving the mask 22 and releases the switch 5 of the mask 22 at that point. When the switch 5 is turned off, the microcomputer 11 moves to position X of the 10(3) table of the management table 3o shown in FIG.
, -β is changed to X3.

Since Y3 was not changed here, its value remains unchanged. Next, when the operator recognizes that the figures of data blocks d4 and d are displayed on the CRT display section 21 and is inputted overlappingly, he moves the cursor into data block d and switches the mouse 22. Turn on 5 (
oN) L, move the mouse 22 so that the pie chart displayed on the CRT display section 21 becomes a correct circle, and select the data block d in the same manner as in the case of the data block d described above.

move. The operator selects data blocks d4 and d
, and when the pie chart is correct, the switch 5 of the mouse 22 is turned off. At this time, the data block ds has moved upward by α dots. By turning off the switch 5, the micro combinator 11 changes Ys-α of the table position X, IY of ID=(5) to YS. At this time, there is an α dot space between data blocks ds and d6, so the operator uses the mouse 22 to move the cursor into data block d6, turns on the switch 5 mentioned above, and displays the screen of the CRT display section 21. While looking at it, move the data block d6 upward and operate the mouse 22 until it becomes a correct pie chart. At this time, since there is no overlap between the image inputs of data blocks d5 and d6, data block d6 is eventually moved upward by α dots. In this way, image data 31, 32, . ... By re-editing 36, correct image data can be obtained.

In the example so far, when data block d3 is input shifted to the right, data blocks d4 and d are input vertically overlapped without shifting to the left or right, but input starts with hand scanner 1. If you start inputting without strictly determining the position and input images by partially overlapping each scan, you can input images using a simple ruler 2, but generally horizontal and vertical displacements occur at the same time. however,
It is clear from the above description that the image data block is moved to the upper left or upper right using the mouse 22, and the values of xi and yt of the table with ID=(i) are obtained from the amount of movement. In addition, in general, data pro tsuku d3 and d
4 * d4 and dB # Between dB and d, images are input with overlapping images when inputting to the scanner.

As described above, when inputting an image, input by the hand scanner 1 can be performed as long as the horizontality of the input paper 3 is not disturbed, and if the images of each scan are scanned while maintaining overlap, the above-mentioned editing of the image data can be done. Correct image data can be easily obtained.

In the above explanation, the image data block management table 30 and the CRT controller 15 were used to move the image data block while the operator looked at the screen on the CRT display section 21. It is also possible to perform block movement processing.◎As mentioned above, when inputting an image using multiple partial scans (scans) using a hand scanner, input with overlapping images in the previous scan and the next scan. This makes it possible to input beautiful images using a simple and inexpensive hand scanner, without requiring accurate positioning of the scanner for each scan. In addition, the positioning of the left side (scan start) of each scan operation of the hand scanner can be done roughly, and furthermore, there is no need to keep the amount of distance from the previous scan constant, so the operation is easy and input can be made quickly.

〔Effect of the invention〕

As described in detail above, according to the image input method of the present invention, by scanning the medium to be read in multiple times with a scanner having a predetermined reading width, the image input method drawn on the medium to be read is detected. In an image input mechanism that inputs an image, read data obtained when the medium to be read is continuously scanned once in a fixed direction by the scanner is read as 1.
The medium to be read is equipped with a means for managing and displaying the image as image input data of a block, and a moving means such as a mouse for moving the displayed image in any one direction in units of blocks. Rather than accurately scanning and inputting the entire surface of , image input operations can be performed easily and quickly, and highly accurate images can be input.
