In this external second embodiment, watermark recovery also can be a pattern of hiding customizing messages in lattice or grid floral designs, can also be described shading image.Fig. 8 represents extracting the picture registration shading image behind the image, thereafter situation about covering with the image that extracts.In this case, identical with first embodiment, control part 10 substitution point pattern generating units 103 have the shading image generating unit.
Image processing apparatus, image processing system and image processing program to third embodiment of the invention describes below.Wherein, for structure and the processing identical, omitted explanation with first or second embodiment.
Fig. 9 is the functional block diagram of electrical structure of the image processing system 1B of expression third embodiment of the invention.
The control part 10 of the image processing system 1B of the 3rd embodiment has imagery zone test section (test section) 105, pixel judging part (judging part) 106, original image generating unit (original image generating unit) 102 and dot pattern generating unit (watermark recovery generating unit) 103.
Detect the coordinate range of image in the represented image of the view data of imagery zone test section 105 from be stored in video memory 13.Because open communique spy opens an example having put down in writing the imagery zone detection method in flat 1-No. 224884 grades at Jap.P., specifies so omitted.
Original image generating unit 102 in the 3rd embodiment is under judging the situation that object pixel is not the pixel in the coordinate range that is detected, carry out on object pixel, overlapping the processing of the particular point pattern that generates by dot pattern generating unit 103, generate original image.On object pixel, overlap the example that the particular point pattern generates the method for original image owing to opening to have put down in writing in 2003-No. 101762, so omitted detailed explanation the open communique spy of Jap.P..
Specify the flow process of the processing that each the function portion of the control part 10 in the 3rd embodiment carried out below with Figure 10.For example in video memory 13, store under the situation of the image 2 shown in Figure 10 A, at the photo or the halftone dot image that comprise in the image 2 as image 21 and image 22.Shown in Figure 10 B, imagery zone test section 105 detects the zone 211 as the coordinate range of image 21 in this case, and detects the zone 221 as the coordinate range of image 22.
Then, pixel judging part 106 judges whether object pixel 23 is the interior pixels of coordinate range in zone 211 or zone 221.Under the situation of the pixel in object pixel 23 is not described coordinate range, original image generating unit 102 overlaps the particular point pattern that is generated by dot pattern generating unit 103 on object pixel 23, and under the situation of the pixel in object pixel 23 is described coordinate range, because object pixel 23 is image 21 or 22 pixels that comprised, so do not carry out the coincidence of particular point pattern.
As mentioned above, pixel judging part 106 for example moves coordinate figure in proper order from the upper left coordinate of image 2, and the pixel of entire image 2 is judged.Figure 10 C is the figure of the image 2 of expression when finishing judgement to whole pixels.Promptly, in the processing of the 3rd embodiment, judge that whether object pixel is the pixel in the coordinate range of image, when not being pixel in the image coordinate scope, on object pixel, overlap the particular point pattern, can be created on the original image that does not overlap the particular point pattern on the image.
In this 3rd embodiment, the memory point pattern overlaps program 111B (the 3rd embodiment of image processing program of the present invention) in storage part 11.Dot pattern overlaps program 111B and is used for detecting imagery zone from the image of pictorial data representation, and the area coincidence particular point pattern beyond this imagery zone is generated original image.That is, control part 10 moves by overlapping program 111B according to described dot pattern, the function of performance imagery zone test section 105, pixel judging part 106, original image generating unit 102 and dot pattern generating unit 103.
But the formation of control part 10 is not limited to overlap by described dot pattern the structure of the function of program 111B performance imagery zone test section 105, pixel judging part 106, original image generating unit 102 and dot pattern generating unit 103, also can comprise the imagery zone test section 105, pixel judging part 106, original image generating unit 102 and the dot pattern generating unit 103 that constitute by circuit respectively.
Figure 11 is the process flow diagram of the control part 10 of the image processing system 1B of expression the 3rd embodiment when carrying out the processing that overlaps the particular point pattern on the image of pictorial data representation.Explanation has been omitted in the processing identical with first or second embodiment.
At first detect coordinate range (the step S31 of image in the represented image of the view data of imagery zone test section 105 from be stored in video memory 13; Be equivalent to Figure 10 B).Pixel judging part 106 judges whether object pixel is the interior pixel (step S32) of coordinate range of image then.Under the situation that is the pixel in the described coordinate range (step S32 is a "Yes"), control part 10 is transferred to step S34 to processing.And under the situation that is not the pixel in the described coordinate range (step S32 is a "No"), the processing (step S33) that original image generating unit 102 makes the particular point pattern overlap with object pixel.
When object pixel is not the pixel of last coordinate figure (step S34 is a "No"), pixel judging part 106 moves coordinate figure on the coordinate position that is altered to the new pixel of expression (step S35), and pixel judging part 106 carries out same judgement (step S32) to the pixel of after changing new coordinate figure as object pixel.On the other hand, when object pixel is the pixel of last coordinate figure (step S34 is a "Yes"), image forming part 16 is printed onto (step S36) on the recording chart to the original images that generate.
As previously discussed, in this 3rd embodiment, when overlapping on the image under the situation of particular point pattern, only the outer pixel of the coordinate range of image is overlapped the particular point pattern, on image, do not dispose the particular point pattern thus, neither reduce the original image that image quality has inserted the particular point pattern again so can generate.
The invention is not restricted to described embodiment, can also carry out various distortion.In described the 3rd embodiment, the image processing system of image processing apparatus with embodiment of the present invention is illustrated, but also for example computing machine such as PC can be image processing apparatus with embodiment of the present invention.
In addition, in the 3rd embodiment, watermark recovery also can be a pattern of hiding customizing messages in lattice or grid floral designs, can also be shading image.With Figure 12 the situation that coincidence shading image on the zone except imagery zone generates original image is described below.
At first, the control part 10 substitution point pattern generating units 103 in the 3rd embodiment have the shading image generating unit.The shading image 3 of expression making and image 2 same sizes in Figure 12.Imagery zone test section 105 detects the coordinate range of the image of image 2 then.Pixel judging part 106 judges whether object pixel 23 is included in the coordinate range shown in zone 211 or the zone 221.Under the situation of the pixel in object pixel 23 is not described coordinate range, original image generating unit 102 carries out overlapping the processing of shading image on object pixel 23.Specifically, the pixel on the shading image 3 with the coordinate figure identical relatively with object pixel 23 and pixel count 31 is overlapped on object pixel 23.
And be under the situation of described coordinate range interior pixel in object pixel 23, because object pixel 23 is image 21 or 22 pixels that comprised, so object pixel 23 is not overlapped shading images.Image 2a represents entire image 2 is carried out the original image that obtains after the above-mentioned processing repeatedly.Like this,, both image quality can be do not reduced, and illegal duplicating can be contained again original copy by only the outer pixel of the coordinate range of image being overlapped shading image.
Image processing apparatus, image processing system and image processing program to four embodiment of the invention describes below.Wherein, for first to the 3rd embodiment same structure and the processing, omitted explanation.
Figure 13 is the functional block diagram of electrical structure of the image processing system 1C of expression four embodiment of the invention.
The control part 10 of the image processing system 1C of the 4th embodiment has imagery zone test section (test section) 105, pixel judging part (judging part) 106, original image generating unit (appendix, original image generating unit) 102, dot pattern generating unit (watermark recovery generating unit) 103 and 2 d code generating unit 104.
2 d code generating unit 104 generates the 2 d code that will be inserted in the image that is comprised by imagery zone test section 105 detected coordinate ranges.This 2 d code is identical with 2 d code in second embodiment.
With Figure 14 the treatment scheme of each function portion of the control part in the 4th embodiment 10 is specifically described below.For example in video memory 13, store under the situation of the image 2 shown in Figure 14 A, in image 2, comprise image 21 and image 22 such photo or halftone dot image.In this case, as shown in Figure 14B, imagery zone test section 105 detects the zone 211 as the coordinate range of image 21, and as the zone 221 of the coordinate range of image 22.
Then, original image generating unit 102 is attached to 2 d code 21a and the 22a that 2 d code generating unit 104 generates respectively on image 21 and 22.The position of additional 2 d code can be set arbitrarily by the user, also can add automatically.Under automatically additional situation, preferably be attached to zone beyond the central part in the image (for example lower corner etc.).
Subsequently, pixel judging part 106 judges whether object pixel 23 is the interior pixels of coordinate range in zone 211 or zone 221.During pixel in object pixel 23 is not described coordinate range, the particular point pattern that original image generating unit 102 generates dot pattern generating unit 103 overlaps with object pixel 23.And during the pixel in object pixel 23 is described coordinate range, because object pixel 23 is image 21 or 22 pixels that comprised, so do not carry out the coincidence of particular point pattern.
In this 4th embodiment, the memory point pattern overlaps program 111C (the 4th embodiment of image processing program of the present invention) in storage part 11.Dot pattern overlaps program 111C and is used for detecting imagery zone from the image of pictorial data representation, and to the area coincidence particular point pattern beyond this imagery zone, additional 2 d code on image generates original image afterwards.That is, control part 10 moves by overlapping program 111C according to described dot pattern, the function of performance imagery zone test section 105, pixel judging part 106, original image generating unit 102, dot pattern generating unit 103 and 2 d code generating unit 104.
But the formation of control part 10 is not limited to be overlapped by described dot pattern the function of program 111C performance imagery zone test section 105, pixel judging part 106, original image generating unit 102, dot pattern generating unit 103 and 2 d code generating unit 104, also can comprise the structure of the imagery zone test section 105, pixel judging part 106, original image generating unit 102, dot pattern generating unit 103 and the 2 d code generating unit 104 that are made of circuit respectively.
Figure 15 is the process flow diagram of the control part 10 of the image processing system 1C of expression the 4th embodiment when carrying out the processing that overlaps the particular point pattern on the image of pictorial data representation.Omitted explanation for the processing identical with first to the 3rd embodiment.
(step S41 when in the image represented, detecting the coordinate range of image by the view data of imagery zone test section 105 from be stored in video memory 13; Be equivalent to Figure 14 B), 102 pairs of original image generating units are included in the additional 2 d code (step S42) of image in the coordinate range that is detected.
Then when judged object pixel by pixel judging part 106 be pixel (step S43 is a "Yes") in the image coordinate scope, control part 10 was transferred to step S45 to processing.And under the situation of the pixel in object pixel is not described coordinate range (step S43 is a "No"), original image generating unit 102 carries out object pixel is overlapped the processing (step S44) of particular point pattern.
When object pixel is not the pixel of last coordinate figure (step S45 is a "No"), pixel judging part 106 moves one to coordinate figure, be altered to the coordinate position (step S46) of the new pixel of expression, pixel judging part 106 carries out same judgement (step S43) to the pixel of after changing new coordinate figure as object pixel.On the other hand, when object pixel is the pixel of last coordinate figure (step S45 is a "Yes"), image forming part 16 is printed on (step S47) on the recording chart to the original images that generate.
As previously discussed, in the 4th embodiment, not only can generate and neither reduce the original image that image quality has inserted the particular point pattern again, also, can contain behaviors such as illegal duplicating or tampered image by to the additional 2 d code that is concealed with predetermined information of image.
The invention is not restricted to described embodiment, can carry out various distortion.In described the 4th embodiment, the image processing system of image processing apparatus with embodiment of the present invention is illustrated, but also for example computing machine such as PC can be image processing apparatus with embodiment of the present invention.
In addition, in the 4th embodiment, watermark recovery also can be a pattern of hiding customizing messages in lattice or grid floral designs, can also be to overlap shading image.With Figure 16 the situation that coincidence shading image on the zone except imagery zone generates original image is described below.
At first, control part 10 substitution point pattern generating units 103 have the shading image generating unit.The shading image 3 with image 2 same sizes has been made in expression in Figure 16.Imagery zone test section 105 detects the image coordinate scope of image 2, and 102 pairs of original image generating units are included in additional respectively 2 d code 21a and 22a on image 21 in the coordinate range that is detected and the image 22.Pixel judging part 106 judges whether object pixel 23 is included in the coordinate range of zone 211 or zone 221 expressions.During pixel in object pixel 23 is not described coordinate range, original image generating unit 102 carries out overlapping the processing of shading image on object pixel 23.Specifically, the pixel on the shading image 3 with the coordinate figure identical relatively with object pixel 23 and pixel count 31 is overlapped on object pixel 23.
During pixel in object pixel 23 is described coordinate range, because object pixel 23 is image 21 or 22 pixels that comprised, so object pixel 23 is not carried out the coincidence of shading image.Image 2a carries out the original image that obtains after the above-mentioned processing repeatedly to entire image 2.Like this,, both image quality can be do not reduced, and the illegal duplicating of original copy can be contained again by only the outer pixel of the coordinate range of image being overlapped shading image.
