Abstract

PURPOSE:To eliminate a need to take the data size of a junction face into consideration and to join data without deviation by judging the junction position by shift operation and exclusive OR operation. CONSTITUTION:In the case of vertical junction between read-in image data 1A and 1B, image data 1A is shifted to the leftmost position with bit operators to cause the right end of image data 1A and the left end of image data 1B to coincide with each other. Exclusive ORs of junction face data of image data 1A and 1B are operated and are stored together with position coordinates at this time. It is judged whether the junction face of image data 1A and 1B can be shifted or not; and if it cannot be shifted, a coordinate X to which the sum of exclusive ORs is closest is detected. Image data are moved to the coordinate X and are coupled. Finally, data in protruding parts of image data are deleted to generate image data 4 having a manageable format.

[0004]

Since the conventional image data joining method is constructed as described above, the data sizes of the image data joining surfaces must be the same.
Further, since the joining is performed only in accordance with the size of the joining surface, there is a problem that the image data of the joining surface is displaced unless the position of the image data of the joining surface is taken into consideration.

The present invention has been made in order to solve the above problems, and it is not necessary to consider the data size of the bonding surface, and to obtain an image data bonding method capable of bonding without deviation. With the goal.

[0006]

The image data joining method according to claim 1 of the present invention determines a joining surface determining means for determining a joining surface of image data to be joined and a joining position of joining object image data. A joining position determining means, a joining processing means for performing joining processing according to a result of the determination, and a data creating means for creating data in which a protruding portion of the joined image data is deleted. While shifting the image data to the left and right along the joint surface as much as possible, the exclusive OR of the joint surface data is summed, and the position where the value is closest to 0 is determined as the joint position. Is.

The image data joining method according to a second aspect of the present invention includes the same means as that of the first aspect, and the joining position determining means determines the joining target image data along the joining surface according to the deviation of the joining surface. While shifting left and right by a specified bit,
Take the sum of exclusive OR between each junction surface data,
The position where the value is closest to 0 is determined as the joining position.

The image data joining method according to a third aspect of the present invention is also provided with the same means, and the joining position determining means shifts the image data to be joined by the designated bit in the direction perpendicular to the joining surface and at each shift position. While shifting to the left and right along the joint surface, the exclusive OR of the respective joint surface data is summed, and the position where the value is closest to 0 is determined as the joint position.

[0009]

In the image data joining method according to the first aspect of the present invention, when joining the image data, the joining surface determining means determines the joining surface, and the joining position determining means performs the shift operation and the exclusive OR operation. The joining position is determined, and the joining processing unit joins the image data based on the determination result. Next, the protruding portion of the joined image data is deleted by the data creating means to create data in a manageable format. Therefore, it is not necessary to consider the data size of the bonded surface, and bonded image data without deviation can be obtained.

Further, according to the second aspect, in addition to the same effect as described above, the processing time can be shortened because it is necessary to shift right and left by a designated bit according to the displacement of the joint surface.

Further, in claim 3, the above-mentioned claim 1
Since it has the same effect as that of (1) and shifts in the direction perpendicular to the joining surface, it is possible to create joining image data with less deviation.

【Example】

Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram according to an embodiment of the present invention,
FIG. 2 is a state diagram of image data joining. In FIGS. 1 and 2, 1A and 1B are image data to be joined, 21 is a joining surface determining means for determining a joining surface of the respective image data 1A and 1B, and 22 is image data 1
Joining position determination means for determining the joining positions of A and 1B, 23
Is a joining processing means for joining the image data according to the determination result of the joining position determination means 22, 3A is the image data after this image data joining processing, and 24 is a protruding portion of the image data 3A joined by the joining processing means 23. Data creating means 4 for deleting data 31 and 32 and creating data in a manageable format is joint image data created by the data creating means 24.
It should be noted that each of the above means is realized by executing a program represented by a flowchart described later by a computer configuring the system.

Next, the operation will be described. The image data 1A and 1B are joined as shown in the flowchart of FIG. When starting in FIG. 3, the image data 1A and 1B to be joined are read in step 5. Next, in step 6, the joint surface (joint position) of the image data 1A and 1B is read by the user. Also, step 7
In, the shift direction of the image data is read from the user. Since the image data is in bit units and the black part is "1" and the white part is "0", if the joining position read in step 6 is vertical joining, step 8
The image data 1A is shifted to the left by using a bit operator so that the right end b of the image data 1A and the left end c of the image data 1B coincide with each other as shown in FIG. Next, in step 9, the exclusive OR of the joint surface data of the image data 1A and 1B is obtained, and the sum is stored together with the position coordinates at that time, and the process proceeds to step 10. In step 10, it is determined whether the joint surface of the image data 1A and 1B can be shifted. If the determination result is that the image data 1A can be shifted (the left end a of the image data 1A and the right end d of the image data 1B do not match), the image data 1A is shifted to the right by 1 bit in step 10A,
Return to step 9. If the determination result in step 10 is not shiftable (the left end a of the image data 1A and the right end d of the image data 1B match as shown in FIG. 5), the joining position is determined in step 11. In the image data, the black portion is "1" and the white portion is "0". Therefore, when the exclusive OR is taken between the data of the joint surface as shown in FIG. 6, there is no deviation in the joint surface. In this case, the sum of exclusive OR is 0. So, in step 11,
The coordinate X in which the sum of exclusive ORs in step 9 is closest to 0 is detected. Next, in step 12, when there is only one coordinate X, the image data is moved to the coordinate X in step 13 and the image data 1A and 1B are joined. Finally, in step 16, the protruding data of the image data 3A created in step 13 is deleted to create image data 4 in a manageable format. If there are a plurality of coordinates X in step 12, the image data are moved to the respective coordinates X in step 13A, the image data 1A and 1B are joined, and in step 14, the respective joining data are output on the screen. In step 15, an appropriate coordinate X is read by the user. Finally, in step 16, the data of the protruding portion of the image data connected at the coordinate X is deleted, and the image data 4 having a manageable format is created.

Example 2. In the first embodiment, step 8
In FIG. 7, the image data 1A is shifted as shown in FIG. 4, but steps 7B and 8B shown in the flowchart of FIG.
By using, it is possible to perform the joining only by the shift processing of only the right and left designated bits as shown in FIG. 8 according to the degree of deviation of the joining surface of the image data. In FIG. 7, in step 5, the joining target image data 1A and 1B are read. Next, in step 6, the image data 1A,
The joint surface (joint position) of 1B is read from the user. In step 7B, the shift direction of the image data and the shift number of the image data are read by the user.
If the user determines that the degree of deviation is large, the user specifies a large shift number, and if the user determines that the deviation is small, the user specifies a small shift number. The image data is in bit units, and the black part is "1" and the white part is "0". Therefore, if the joining position read in step 6 is vertical joining, the data read in step 8B in step 8B. Based on the above, the image data 1A is shifted to the left by the designated bit using the bit operator, and the point e on the right side of the designated bit from the left end a of the image data 1A and the left end c of the image data 1B are matched as shown in FIG. Next, step 9
Then, the exclusive OR of the joint surface data of the image data 1A and 1B is obtained, and the sum is stored together with the position coordinates at that time, and the process proceeds to step 10B. In step 10B, it is determined whether the image data 1A has been shifted by the designated bit. If the result of determination is that the designated bit has not been shifted (the point f on the left side of the designated bit from the right edge b of the image data 1A and the right edge d of the image data 1B do not match), the image data 1 is determined in step 10A.
A is shifted right by 1 bit and the process returns to step 9 (the designated bit in this case is the shift number read in step 7B). If the determination result is shifted by the designated bit in step 10B (the point f of the image data 1A and the right end d of the image data 1B coincide with each other as shown in FIG. 9), the joining position is determined in step 11. In the image data, the black part is "1" and the white part is "0". Therefore, if the exclusive OR is performed between the data on the joint surface as shown in FIG. 6, there is no deviation on the joint surface. In this case, the sum of exclusive OR is 0. Therefore, in step 11, the sum of exclusive ORs in step 9 is the most zero.
The coordinate X close to is detected. Next, in step 12, if there is only one coordinate X, the image data is moved to the coordinate X in step 13, and the image data 1
Join A and 1B. Finally, in step 16, the protruding data of the image data 3A created in step 13 is deleted to create image data 4 in a manageable format. When there are a plurality of coordinates X in step 12, the image data is moved to the respective coordinates X in step 13A, the image data 1A and 1B are joined, and in step 14, the respective joining data are output on the screen. In step 15, an appropriate coordinate X is read from the user. Finally, in step 16, the data of the protruding portion of the image data connected at the coordinate X is deleted, and the image data 4 having a manageable format is created.

Example 3. In the first embodiment, step 8
In, only data was shifted only in the lateral direction of the joint surface. However, the image data to be joined is the data read by an image scanner, etc., but in that case, depending on how the data is read, not only in the horizontal direction,
There is a high possibility that it will also be displaced vertically. Therefore, FIG.
If a vertical shift is added as shown in the flowchart of FIG. 3, a more appropriate joining position can be obtained. Figure 10
In step 5, the joining target image data 1A, 1
Read B. Next, in step 6, the joint surface (joint position) of the image data 1A and 1B is read by the user. In step 7C, the shift number of image data is read by the user. If the user determines that the degree of deviation is large, the user specifies a large shift number, and if the user determines that the deviation is small, the user specifies a small shift number. Since the image data is in bit units and the black part is "1" and the white part is "0", if the joining position read in step 6 is vertical joining, step 8
Based on the data read in step 7C in C, the image data 1A is shifted downward by a designated bit using a bit operator (the designated bit in this case is the shift number read in step 7C), and in step 8D the image data 1A is read. Is shifted all the way to the left, and a point g above the right end b of the image data 1A and the left end c of the image data 1B coincides with the specified bit as shown in FIG.
Next, in step 9, the exclusive OR of the joint surface data of the image data 1A and 1B is calculated, and the sum is stored together with the position coordinates at that time, and the process proceeds to step 10C. In step 10C, it is determined whether the image data 1A can be shifted to the right (whether the point h above the designated bit at the left end a of the image data 1A and the right end d of the image data 1B do not coincide with each other as shown in FIG. 12). If it can be shifted, the image data 1A is shifted to the right by 1 bit in step 10A, and the process returns to step 9. When the shift is impossible in the state of FIG. 12, the process proceeds to step 10D. In step 10D, it is determined whether or not the bit shift of the image data 1A is completed, and if the result of the determination is not yet completed (the left edge a of the image data 1A and the right edge d of the image data 1B do not match), step 10E. In, the image data 1A is shifted up by 1 bit, and the process returns to step 8D. The determination result of step 10D is the bit shift end (as shown in FIG. 13, the left end a of the image data 1A and the right end d of the image data 1B match).
In the case of, the joining position is determined in step 11.
In the image data, the black part is "1" and the white part is "0".
Therefore, as shown in FIG. 6, when the exclusive OR of the data on the joint surface is calculated, the sum of the exclusive OR is 0 when there is no deviation on the joint surface. Therefore, in step 11, the coordinate X in which the sum of the exclusive ORs in step 9 is closest to 0 is detected. Next, when there is only one coordinate X in step 12, the image data is moved to the coordinate X in step 13 and the image data 1A and 1B are joined. Finally, in step 16, the data of the protruding portion of the image data 3A created in step 13 is deleted, and the image data 4 of a manageable format is deleted.
To create. If there are a plurality of coordinates X in step 12, each coordinate X in step 13A.
Move the image data to the image data 1A, 1
B is joined, each joining data is output on the screen in step 14, and an appropriate coordinate X is read from the user in step 15. Finally, in step 16, the data of the protruding portion of the image data connected at the coordinate X is deleted, and the image data 4 having a manageable format is created.

A joining position determining means, a joining processing means for performing joining processing according to a result of the determination, and a data creating means for creating data in which a protruding portion of the joined image data is deleted. While shifting the image data to the left and right along the joint surface as much as possible, the exclusive OR of the joint surface data is summed, and the position where the value is closest to 0 is determined as the joint position. Is.

The image data joining method according to a second aspect of the present invention includes the same means as that of the first aspect, and the joining position determining means determines the joining target image data along the joining surface according to the deviation of the joining surface. While shifting left and right by a specified bit,

[0012]

EXAMPLES Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram according to an embodiment of the present invention,
FIG. 2 is a state diagram of image data joining. In FIGS. 1 and 2, 1A and 1B are image data to be joined, 21 is a joining surface determining means for determining a joining surface of the respective image data 1A and 1B, and 22 is image data 1
Joining position determination means for determining the joining positions of A and 1B, 23
Is a joining processing means for joining the image data according to the determination result of the joining position determination means 22, 3A is the image data after this image data joining processing, and 24 is a protruding portion of the image data 3A joined by the joining processing means 23. Data creating means 4 for deleting data 31 and 32 and creating data in a manageable format is joint image data created by the data creating means 24.
It should be noted that each of the above means is realized by executing a program represented by a flowchart described later by a computer configuring the system.

Next, the operation will be described. The image data 1A and 1B are joined as shown in the flowchart of FIG. When starting in FIG. 3, the image data 1A and 1B to be joined are read in step 5. Next, in step 6, the joint surface (joint position) of the image data 1A and 1B is read by the user. Also, step 7
In, the shift direction of the image data is read from the user. Since the image data is in bit units and the black part is "1" and the white part is "0", if the joining position read in step 6 is vertical joining, step 8
The image data 1A is shifted to the left by using a bit operator so that the right end b of the image data 1A and the left end c of the image data 1B coincide with each other as shown in FIG. Next, in step 9, the exclusive OR of the joint surface data of the image data 1A and 1B is obtained, and the sum is stored together with the position coordinates at that time, and the process proceeds to step 10. In step 10, it is determined whether the joint surface of the image data 1A and 1B can be shifted. If the determination result is that the image data 1A can be shifted (the left end a of the image data 1A and the right end d of the image data 1B do not match), the image data 1A is shifted to the right by 1 bit in step 10A,
Return to step 9. If the determination result in step 10 is not shiftable (the left end a of the image data 1A and the right end d of the image data 1B match as shown in FIG. 5), the joining position is determined in step 11. In the image data, the black portion is "1" and the white portion is "0". Therefore, when the exclusive OR is taken between the data of the joint surface as shown in FIG. 6, there is no deviation in the joint surface. In this case, the sum of exclusive OR is 0. So, in step 11,
The coordinate X in which the sum of exclusive ORs in step 9 is closest to 0 is detected. Next, in step 12, when there is only one coordinate X, the image data is moved to the coordinate X in step 13 and the image data 1A and 1B are joined. Finally, in step 16, the protruding data of the image data 3A created in step 13 is deleted to create image data 4 in a manageable format. If there are a plurality of coordinates X in step 12, the image data are moved to the respective coordinates X in step 13A, the image data 1A and 1B are joined, and in step 14, the respective joining data are output on the screen. In step 15, an appropriate coordinate X is read by the user. Finally, in step 16, the data of the protruding portion of the image data connected at the coordinate X is deleted, and the image data 4 having a manageable format is created.

Example 2. In the first embodiment, step 8
In FIG. 7, the image data 1A is shifted as shown in FIG. 4, but steps 7B and 8B shown in the flowchart of FIG.
By using, it is possible to perform the joining only by the shift processing of only the right and left designated bits as shown in FIG. 8 according to the degree of deviation of the joining surface of the image data. In FIG. 7, in step 5, the joining target image data 1A and 1B are read. Next, in step 6, the image data 1A,
The joint surface (joint position) of 1B is read from the user. In step 7B, the shift direction of the image data and the shift number of the image data are read by the user.
If the user determines that the degree of deviation is large, the user specifies a large shift number, and if the user determines that the deviation is small, the user specifies a small shift number. The image data is in bit units, and the black part is "1" and the white part is "0". Therefore, if the joining position read in step 6 is vertical joining, the data read in step 8B in step 8B. Based on the above, the image data 1A is shifted to the left by the designated bit using the bit operator, and the point e on the right side of the designated bit from the left end a of the image data 1A and the left end c of the image data 1B are matched as shown in FIG. Next, step 9
Then, the exclusive OR of the joint surface data of the image data 1A and 1B is obtained, and the sum is stored together with the position coordinates at that time, and the process proceeds to step 10B. In step 10B, it is determined whether the image data 1A has been shifted by the designated bit. If the result of determination is that the designated bit has not been shifted (the point f on the left side of the designated bit from the right edge b of the image data 1A and the right edge d of the image data 1B do not match), the image data 1 is determined in step 10A.
A is shifted right by 1 bit and the process returns to step 9 (the designated bit in this case is the shift number read in step 7B). If the determination result is shifted by the designated bit in step 10B (the point f of the image data 1A and the right end d of the image data 1B coincide with each other as shown in FIG. 9), the joining position is determined in step 11. In the image data, the black part is "1" and the white part is "0". Therefore, if the exclusive OR is performed between the data on the joint surface as shown in FIG. 6, there is no deviation on the joint surface. In this case, the sum of exclusive OR is 0. Therefore, in step 11, the sum of exclusive ORs in step 9 is the most zero.
The coordinate X close to is detected. Next, in step 12, if there is only one coordinate X, the image data is moved to the coordinate X in step 13, and the image data 1
Join A and 1B. Finally, in step 16, the protruding data of the image data 3A created in step 13 is deleted to create image data 4 in a manageable format. When there are a plurality of coordinates X in step 12, the image data is moved to the respective coordinates X in step 13A, the image data 1A and 1B are joined, and in step 14, the respective joining data are output on the screen. In step 15, an appropriate coordinate X is read from the user. Finally, in step 16, the data of the protruding portion of the image data connected at the coordinate X is deleted, and the image data 4 having a manageable format is created.

Example 3. In the first embodiment, step 8
In, only data was shifted only in the lateral direction of the joint surface. However, the image data to be joined is the data read by an image scanner, etc., but in that case, depending on how the data is read, not only in the horizontal direction,
There is a high possibility that it will also be displaced vertically. Therefore, FIG.
If a vertical shift is added as shown in the flowchart of FIG. 3, a more appropriate joining position can be obtained. Figure 10
In step 5, the joining target image data 1A, 1
Read B. Next, in step 6, the joint surface (joint position) of the image data 1A and 1B is read by the user. In step 7C, the shift number of image data is read by the user. If the user determines that the degree of deviation is large, the user specifies a large shift number, and if the user determines that the deviation is small, the user specifies a small shift number. Since the image data is in bit units and the black part is "1" and the white part is "0", if the joining position read in step 6 is vertical joining, step 8
Based on the data read in step 7C in C, the image data 1A is shifted downward by a designated bit using a bit operator (the designated bit in this case is the shift number read in step 7C), and in step 8D the image data 1A is read. Is shifted all the way to the left, and a point g above the right end b of the image data 1A and the left end c of the image data 1B coincides with the specified bit as shown in FIG.
Next, in step 9, the exclusive OR of the joint surface data of the image data 1A and 1B is calculated, and the sum is stored together with the position coordinates at that time, and the process proceeds to step 10C. In step 10C, it is determined whether the image data 1A can be shifted to the right (whether the point h above the designated bit at the left end a of the image data 1A and the right end d of the image data 1B do not coincide with each other as shown in FIG. 12). If it can be shifted, the image data 1A is shifted to the right by 1 bit in step 10A, and the process returns to step 9. When the shift is impossible in the state of FIG. 12, the process proceeds to step 10D. In step 10D, it is determined whether or not the bit shift of the image data 1A is completed, and if the result of the determination is not yet completed (the left edge a of the image data 1A and the right edge d of the image data 1B do not match), step 10E. In, the image data 1A is shifted up by 1 bit, and the process returns to step 8D. The determination result of step 10D is the bit shift end (as shown in FIG. 13, the left end a of the image data 1A and the right end d of the image data 1B match).
In the case of, the joining position is determined in step 11.
In the image data, the black part is "1" and the white part is "0".
Therefore, as shown in FIG. 6, when the exclusive OR of the data on the joint surface is calculated, the sum of the exclusive OR is 0 when there is no deviation on the joint surface. Therefore, in step 11, the coordinate X in which the sum of the exclusive ORs in step 9 is closest to 0 is detected. Next, when there is only one coordinate X in step 12, the image data is moved to the coordinate X in step 13 and the image data 1A and 1B are joined. Finally, in step 16, the data of the protruding portion of the image data 3A created in step 13 is deleted, and the image data 4 of a manageable format is deleted.
To create. If there are a plurality of coordinates X in step 12, each coordinate X in step 13A.
Move the image data to the image data 1A, 1
B is joined, each joining data is output on the screen in step 14, and an appropriate coordinate X is read from the user in step 15. Finally, in step 16, the data of the protruding portion of the image data connected at the coordinate X is deleted, and the image data 4 having a manageable format is created.
