Abstract

PURPOSE:To synthesize basic images without making the joint of overlapped parts conspicuous by overlapping the basic images and also continuously chang ing the overlapped parts in the case of repetitively displaying the basic images. CONSTITUTION:Image data 6 are the data of an object to be fringed by overlapping basic data 5 at edge parts to generate repetitive images. On the other hand, an overlap processing part 10 generates the repetitive images by repetitively overlapping the basic images 5 at the edge parts to generate the repetitive images or mixes and distributes colors corresponding to the attribute information of positions for plural picture elements at the same position with the picture element positions in an overlap width as the attribute information concerning the display color of the overlapped picture element part linking these edge parts with each other, and the display color of the picture element at that position is decided. Then, the overlap processing part 10 forms the repetitive images of the basic images 5 linked at the edge parts by repeatedly using the basic images 5 and displays the images so that the image data 6 can be fringed with the formed repetitive images.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image synthesizing method for synthesizing images obtained by repeating basic images.

[0002]

2. Description of the Related Art Conventionally, when a repeating pattern is displayed like a frame (frame) of a painting, a part of the repeating pattern A is repeatedly displayed as shown in FIG. . Hereinafter, FIG. 8 will be briefly described.

FIG. 8 shows an explanatory view of the prior art. In FIG. 8, an image A is a part of a repeating pattern, and is a pattern that appears repeatedly, for example, a pattern on the frame of a painting.

Next, the procedure for displaying will be described. (1) The original image A is read by a camera or a scanner. (2) When the image A read in (1) is L shorter than the length l to be displayed as shown in FIG. 8, the images A are repeatedly connected and displayed until a desired length is reached.

[0005]

As shown in FIG. 8 described above, when the original image A is read by a camera, a scanner, or the like, the brightness of the image at the left end and the right end of the image A depends on the reading condition. Color difference occurs. Therefore, when the image A having the difference is repeatedly connected and displayed as shown in FIG. 8, a difference in lightness or color occurs at the joint, and the discontinuity of the image occurs at the joint portion of A in FIG. For this reason, there is a problem in that it causes a sense of discomfort to the observer when selecting a pattern as the edging of the painting, and there is a risk that the frame pattern is selected incorrectly.

In order to solve this problem, according to the present invention, when the basic image is repeatedly displayed, the overlapped portions and the overlapped portions are continuously changed so that the joints of the overlapped portions are inconspicuous. Is intended.

[0007]

[Means for Solving the Problems] Means for solving the problems will be described with reference to FIG. In FIG. 1, a basic image 5 is a basic image that is repeatedly displayed.

The image data 6 is the image data to be framed by overlapping the basic data 5 at the ends to generate a repeated image. The superimposition processing unit 10 repeats the basic image 5 to generate a repetitive image by superimposing it on the ends, and for the display color of the overlapping pixel portions connecting the ends, the pixel position within the overlapping width is attribute information. For example, a plurality of pixels at the same position are color-mixed according to the attribute information of the position, and the display color of the pixel at the position is determined.

The enlargement / reduction processing unit 8 enlarges or reduces the image data 6 and the basic image 5 of the painting to a desired size when superimposing the basic image 5 of the frame on the image data 6 of the painting.

[0010]

According to the present invention, as shown in FIG. 1, the superposition processing unit 10 repeatedly uses the basic image 5 to form an iterative image of the basic image 5 which is continuous at the edges, and the formed repetitive image is used. The image data 6 is displayed so as to be framed.

Further, the superimposition processing unit 10 connects the end portions of the basic image 5 so that a plurality of pixel portions overlap each other, and regarding the display colors of the overlapping pixel portions, the pixel positions within the overlapping width are set to the same position as attribute information. A plurality of pixels are color-mixed according to the attribute information of the position, and the display color of the pixel at the position is determined.

Further, when the enlargement / reduction processing unit 8 borders the image data 6 with the basic image 5, the image data 6 is enlarged or reduced according to the number of display pixels at the display position, and the enlargement or reduction is performed. The basic image 5 is enlarged or reduced according to the size of the image data 6.

At this time, the display color of the pixel is based on the three primary colors of red (R), green (G), and blue (B), and is performed for each primary color. As the display color of the pixel, a display color system having attributes of hue (H), luminance (V) and saturation (S), or a display color system based on luminance (Y) and color difference (Cr, Cb) is used. I am going to do it for each attribute.

Further, in edging, color mixture is distributed to the connecting portion of repeated images. Therefore, basic image 5
When repeatedly displaying, the overlapping portions and the overlapping portions are continuously changed, so that the joints of the overlapping portions can be combined inconspicuously.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the construction and operation of an embodiment of the present invention will be sequentially described in detail with reference to FIGS.

FIG. 1 shows a block diagram of an embodiment of the present invention.
In FIG. 1, a camera 1 or a scanner 2 captures and reads a basic image 5 that is repeatedly displayed, and reads image data 6 of a painting. The basic image 5 and the image data 6 are read as R, G, and B multivalues for each pixel.

The reading unit 3 includes the camera 1 or the scanner 2.
The basic image 5 and the image data 6 of a painting are read from. The storage unit 4 stores the basic image 5 that is repeatedly displayed by the reading unit 3, and is, for example, a hard disk device.

The basic image 5 is an image (images of R, G, B, etc.) that is repeatedly displayed. The image data 6 is image data of a painting (image data of R, G, B, etc.) and the like.

The storage unit 7 temporarily stores image data of paintings and the like. The enlargement / reduction processing unit 8 enlarges / reduces the image data extracted from the storage unit 7, enlarges / reduces the basic image 5 extracted from the storage unit 4, and scales to a size for display or the like.

The temporary storage 9 stores the basic image 5 and the image data 6 which are enlarged / reduced to have the same size as the display. The superimposition processing unit 10 extracts the scaled basic image 5 from the temporary storage 9, repeats the basic image 5 by superimposing the basic image 5, and for the pixels of the overlapping portion at this time, the attribute value of the overlapping portion of the pixels for each line ( For example, the R component) is distributed toward the end so as to have a predetermined value (for example, 0). In the case of the basic images 5 arranged on the left and right, this process is performed for each basic image 5. The attribute values (for example, the R component) of the overlapping portions of these distributed two are combined.

The display memory 11 is a memory (frame memory) for storing and displaying the scaled image data 6 and an image obtained by overlapping and scaling the scaled basic image 5 and the like.

The display 12 displays an image in which the image data 6 and the basic image 5 stored in the display memory 11 are overlapped and repeated, and the like. FIG. 2 shows a conceptual explanatory view of the present invention.

FIG. 2A shows an example of superposition of the basic images 5. This is a pattern in which the image A is overlapped and repeated as the basic image 5. By providing the overlapping portion and repeating the image A, the overlapping portion, which will be described later, is combined to make the joints inconspicuous.

FIG. 2B shows an example of overlapping portions of the basic image 5. In this case, first, the image A on the left end is displayed, and then, when the image A ′ is displayed, the number of pixels corresponding to a predetermined number of dots (D in the drawing) is overlapped. This allows
A portion where the image A and the image A ′ overlap by D is provided.

FIG. 2 (c) shows an example of composition of overlapping portions. Here, image A is the image already displayed,
The image A ′ is an image to be displayed from now on, and the contents are exactly the same. When the image A ′ is displayed, the image A ″ superimposed by the right D dots of the image A is displayed. Specifically,
When D = 6 dots, the image A ″ is overlaid as follows.

The image (6) and the image A'are superposed. • Overlay (5) of image A and image A '. • Overlay (4) of image A and image A '.

The image A (3) and the image A'are superposed. • Overlay (2) of image A and image A '. • Overlay (1) of image A and image A '.

When the superposed image A ″ (n) is expressed by an equation, the following equation (1) is obtained. Here, n is the number of dots from the right end of the image A, and
It is an integer value from 1 to D. D is the number of pixels in the overlapping portion. A (n) is the value (R, G, B) of the pixel of the nth dot of the image A. A '(D-n) is the pixel value (R, G, B) of the (D-n) th dot of the image A'.

FIG. 2D shows an example of changes in the overlapping portion. By synthesizing the overlapping part as the image A ″ as shown in FIG. 2C, the weight of the part of the image A ″ is strongly influenced by the image A on the left side and becomes weaker toward the right side. At the same time, it is strongly influenced by the image A ′. For this reason, the image A gradually changes from the image A to the image A ′, and the overlapping portion can be made inconspicuous. The details will be sequentially described below.

FIG. 3 is a diagram for explaining the operation of the present invention. This is a procedure when the basic image 5 is read and the overlapping portions are combined. In FIG. 3, S1 performs initial setting. Here, the initial settings are: -Overlap width value: D-Calculation unit: Pixel unit. In this case, as shown in FIG. 4, the overlapping width of the image A and the image A ′ is D dots. The calculation unit is pixel unit.

In step S2, the basic image 5 is read. The superimposition processing unit 10 in FIG. 1 reads the basic image 5 from the temporary storage 9. In S3, the width (the number of lines) of the basic image 5 is set.

In S4, the pixel value of the overlapping portion of A is distributed so that it becomes 0 toward the right end. As shown in FIG. 4, the weighted S of the image A in FIG. 4 is distributed so that the overlapping portion becomes 0 toward the right end. As a result, the influence of the image A on the pixel value of the overlapping portion of the image A gradually decreases toward the right end.

In S5, the pixel value of the overlapping portion of A'is distributed so that it becomes 0 toward the left end. This is as indicated by the dotted line labeled S ′ in image A ′ in FIG.
The overlapping part is distributed so that it becomes 0 toward the left end.
As a result, the pixel value of the overlapping portion of the image A ′ gradually reduces the influence of the image A ′ toward the left end.

In step S6, the overlapping portions of the two are combined. This is because the weighted S of A and the weighted S ′ of A ′ described by the dotted line in FIG. 4 are combined (added) for each point,
Image A ″ as described as S ″, which is a composite of A and A ′
(See equation (1)).

In step S7, it is determined whether the number of lines (width) is over. In the case of YES, since distribution and combination have been completed for all overlapping portions, the process proceeds to S8. On the other hand, if NO, S4 and subsequent steps are repeated for the next line portion.

S8 is displayed. This is YES in S7
Then, since the distribution and combination of all the dots in the overlapping portion are completed, the image A ″ obtained by combining A and A ′ of FIG.
Is displayed as an overlapping part on the screen.

As described above, the read basic images 5 are overlapped by the overlapping width D, and the inside of the overlapping width D is shown in FIG.
After the overlapping portion of the image A is distributed to 0 toward the edge and the overlapping portion of the image A ′ is distributed to 0 toward the edge, both are combined to obtain and display the image A ″ of the overlapping portion. As a result, the portion of the image A ″ in which the image A and the image A ′ are superimposed and combined gradually changes from the image A to the image A ′, and the overlapping portions can be connected inconspicuously.

FIG. 4 shows a synthetic explanatory view of the present invention. Here, the image A is the same basic image 5 as the image A ′,
It is an image to be superimposed, and D dots are overlapped.
In this overlapped D dot portion, A
As indicated by the dotted line denoted by the weighted S, the pixel value of the overlapping portion is distributed so as to gradually become 0 toward the end. Similarly, for image A ', weighted S'of A'
As shown by the dotted line described as, the overlapping portion is distributed so that it gradually becomes 0 toward the end. Then, both of these distributed portions are combined, and the image A ″ of the overlapping portion is combined as indicated by a dotted line described as S ″, which is a combination of A and A ′. By this combination, the image A ″ of the overlapping portion gradually changes from the image A to the image A ′.

FIG. 5 shows a superposition flowchart of the present invention. This is a procedure when the image A ″ is generated by allocating the overlapping portions and synthesizing them by the above-mentioned formula (1).

In FIG. 5, S11 displays the basic image A. This displays the image A which is the basic image 5 as shown in FIG. 4, for example. At S12, attention is paid to the overlapping portion A ″. This is image A and image A'in FIG.
Pay attention to the overlapping portion A ″ of.

In S13, the number of dots from the right end of A is set to n (n = 1 to an integer from D). In S14, n / D is calculated. In S15, the value of the nth dot from the right end of the original basic image A is multiplied. When expressed by an equation, (n / D) × A (n) is calculated. That is, the value of the value A (n) at the nth dot from the right end of the original basic image A is multiplied by n / D calculated in S14 to obtain the value of (n / D) × A (n).

In S16, the same point is from the left end of A '(D-
n) The dot position. This is because the number of dots in the overlapping portion in FIG. 4 is D, and the same point as the nth dot calculated in S15 is the position of (D−n) dots from the left end of A ′.

In step S17, (D-n) / D is calculated. S
18 multiplies the value of the (D−n) th dot from the left end of the original basic image A ′. When expressed by a formula, ((D−n) / D) × A ′ (D−n) is calculated. That is, from the left end of the original basic image A '(D-
(n) The value of the dot value A ′ (D−n) is multiplied by (D−n) / D calculated in S17 to obtain ((D−n) / D) × A ′.
The value of (D-n) is calculated.

In step S19, it is determined whether n = 0 to D have been completed. If YES, the process ends (end). On the other hand, in the case of NO, the process proceeds to the next dot. As described above, it is possible to combine the image A ″ of the overlapping portion of the image A and the image A ′ in FIG. 4 by applying the above-described formula (1).

For the sake of convenience in the above description, it is assumed that the pixel attribute is, for example, each of the three primary colors of red (R), green (G), and blue (B), but the display color system of the pixel is limited to this. Alternatively, the hue (H), the brightness (V), the saturation (S), the brightness (Y), the color difference (Cr, Cb), or the like may be used.

FIG. 6 shows a frame composition flow chart of the present invention. This is a procedure for synthesizing overlapping portions when repeatedly arranging the basic image 5 of the frame around the image data 6 of the painting.

In FIG. 6, in step S21, the image data and size of the painting are read. For example, as shown in FIG. 7A, the image data 6 of the painting and its size (here, H2) are read.

In S22, the temporary storage a is stored. This stores the image data 6 and the size of the painting read in S21 in the storage unit 7 of FIG. In step S23, various frame image data (basic image 5) and size data are read and stored in the image data file 13.

In step S24, the basic image 5 used for the frame is selected. For this, the user selects a suitable one from the image data files 13 for the frame.
For example, the basic image A is selected.

In step S25, in order to match the size of the picture with the selected basic image A, each image is enlarged / reduced to the same scale and stored (scaled) in the temporary storage b.
As will be described later with reference to the flowchart of FIG. 7B, this is the original dot number and size of the image data 6 of the painting read in S21, and the basic image 5 selected in S24.
Based on the original number of dots and size of the
The scale is reduced to the same scale and stored in the temporary storage 9 of FIG. As a result, the image data 6 and the basic image 5 of the painting are scaled to the same scale when arranged on the screen.

A step S26 displays the painting data in the temporary storage. The painting data having the same scale in S25 is first displayed on the screen, for example, in the center as shown in the painting data in FIG. In S27, the frame image is displayed above and below the displayed painting. At this time, when the length of the basic image 5 is shorter than the length of the frame to be displayed, the same images are repeatedly displayed while being overlapped to extend the length. As a result, for example, a frame in which the basic image A is superimposed is displayed on the upper and lower portions of the data of the central painting shown in FIG.

Similarly, in S28, the frame images are displayed on the left and right of the displayed painting. At this time, if the length of the selected basic image 5 is shorter than the length of the frame to be displayed,
Display the same image repeatedly while overlapping it to extend the length. As a result, for example, a frame in which the basic image A is superimposed is displayed on the left and right portions of the data of the central painting shown in FIG. 7A.

In S29, the user determines from the combined picture and picture of the picture frame whether the picture and the picture frame match. If it matches, the data of the painting is displayed in the center, and the basic image 5 of the picture frame is displayed above and below, left and right of the picture, and it is determined that the picture matches the picture frame. S30
Use the picture frame selected in to complete the actual painting and finish. On the other hand, if they do not match, the process returns to S24 and the basic image 5 of another frame is selected again.

As described above, when the user selects the basic image 5 of the frame used for inputting and combining the image data 6 of the painting, the image data 6 of the painting and the basic image 5 are automatically selected.
After the scaling is performed, the image data 6 of the painting is displayed, and the basic image 5 is displayed on the upper / lower side and the right / left side, that is, the picture and the frame are displayed on the screen. When the user who sees this judges that the painting and the picture frame match, the actual picture is completed using the selected picture frame. On the other hand, if you decide that the picture does not match the frame, select another frame,
repeat. As a result, a part of the repeating pattern is saved as the basic image 5 of the frame, and is superimposed and displayed when the frame is displayed, and the overlapping and allocating and combining are performed so as to change gradually. As a result, the overlapping parts of the frame can be seen continuously, and the overlapped parts become inconspicuous.

FIG. 7 shows a scaling explanatory diagram of the present invention. FIG. 7A shows an arrangement example. This is an example of arranging a picture and a frame on the display screen. Here, the image data 6 at the center is a portion that displays the data of the painting, and the upper and lower sides and the left and right of the periphery thereof are the portions that display the basic image 5 (here, the basic image A of the frame). Each symbol in the figure represents the following. The horizontal size and the number of dots are omitted.

H1: the size of the upper part on which the basic image A is placed H2: the size of the image data (painting data) placed on it H1: the size of the lower part on which the basic image A is placed M: display screen Total Number of Dots Next, the scaling of the image data 6 and the basic image 5 will be described in detail according to the order shown in the flowchart of FIG.

In FIG. 7 (b), S31 calculates the total length (mm) after combination. Here, it is calculated from (a) of FIG. 7 as H1 + H2 + H1.

In S32, the number M of dots in the entire display screen is taken out. In S33, the original dot number a of the basic image A and the original dot number b of the image data (painting) are counted.

In S34, the dot number a'when the basic image A is drawn is given by the ratio H1 of the A portion in which M is divided into H1: H2: H1. That is, the number of dots a ′ at the time of drawing the basic image A is given by a ′ = M × H1 / (H1 + H2 + H1).

In step S35, the expansion / contraction is performed so that a becomes a '. In S36, the dot number b'when the image data (painting) is drawn is given by the ratio H2 of the image data portion in which M is divided into H1: H2: H1. That is, b ′ = M × H2 / (H1 + H2 + H1) gives the number of dots b ′ at the time of drawing the image data.

In step S37, b is expanded or contracted to b '. By the above, the image data 6 of the painting and the number of dots of the basic image 5 of the selected frame, the size and the total number of dots on the display screen, the size of the painting and the frame to be arranged are scaled up and down, and the same scale is obtained when the image is arranged on the screen. Scale to. As a result, the preparation for displaying the basic image 5 by superimposing it on the frame portion described above is completed.

[0062]

As described above, according to the present invention,
When the basic image 5 is repeatedly displayed, a configuration is adopted in which the overlapping portions and the overlapping portions are continuously changed. Therefore, the joints of the overlapping portions can be combined inconspicuously. In particular, it is possible to prevent the conspicuousness of the joints and the deterioration of the image quality that occur when the basic image 5 is simply connected to one image as in the conventional case, and it is possible to display smoothly and neatly. Therefore, when selecting the frame of the painting for display, it is possible to select the pattern of the frame that effectively impresses the viewer on the painting without error.

Further, the amount of frame images to be saved can be reduced and the memory capacity can be reduced as compared with the case where a large frame image is registered in advance so as not to make a joint and the required length is cut out.
