With reference to Fig. 3～Fig. 8, the image processing of implementing is described in the personal computer 20 relevant with the 1st embodiment.Fig. 3 is the flow chart that is illustrated in the handling procedure of the image processing of implementing in the personal computer 20 relevant with the 1st embodiment.Fig. 4 is the key diagram of image (image) example of pattern ground expression decorative picture data.Fig. 5 is the key diagram of the file structure of the pattern ground expression decorative picture file FF that possesses decorative picture data FD and layout control information LI.Fig. 6 is the key diagram of the file structure of the pattern ground expression photographed images file that possesses photographed images data GD and image processing control information GI.Fig. 7 is the key diagram that an example of the look distribution character that the result of decorative picture data FD obtains is resolved in expression.Fig. 8 is the key diagram of an example that expression is used for trying to achieve from the look distribution character value I of decorative picture data FD the curve chart of correction k.In addition, the image example of decorative picture data FD is illustrated in the state when launching on the frame buffer conceptually, again, and the state the when file structure of each file is also represented to be stored in the memory conceptually.
The image processing of Shi Shiing in the present embodiment, for example, both can work as when being installed in storage card MC in the personal computer 20, perhaps, when digital still video camera 10 is connected with personal computer 20 through telecommunication cables, also can works as and pass through keyboard etc. and indicate by the user and implement when carrying out image processing.
Personal computer 20 (CPU200) when the beginning image processing, is obtained selected decorative picture data FD, temporarily is stored in (step S100) among the RAM201.The selection of decorative picture data FD for example, also can be carried out on digital still video camera 10, perhaps, also can be on personal computer 20 from be stored in the decorative picture data the HDD202 in advance, select, perhaps, also can select through network through keyboard etc.In addition, decorative picture data FD also can have a plurality of allocation positions that are used to dispose a plurality of photographed images data GD, in the present embodiment, for the purpose of easy explanation, explanation is attached to situation among the decorative picture data FD with 1 allocation position with single (1) photographed images data GD.
Decorative picture data FD, for example, (when frame buffer launches) has form shown in Figure 4 when output image, is ready to the allocation position that one or more are used to attach photographed images data GD.
In the form of the decorative picture file FF that possesses decorative picture data FD and layout control information L1, handle decorative picture data FD.Decorative picture file FF, for example, possesses file structure shown in Figure 5, the allocation position information that layout control information L1 regulation will dispose photographed images data GD (for example, and the configuration sized (adjustment size) of the photographed images data GD in the specified configuration position, further also can stipulate the look distribution character information of decorative picture data FD coordinate information).
Further α channel data (channel data) is recorded and narrated in layout control information L1.The α channel data, for example, be (for example relatively to adjust view data that image is positioned at upper layer side when synthetic, decorative picture data FD) and the view data that is positioned at lower layer side (for example, photographed images data GD) in each gray-level value (R, G, B data value), is used to determine to be positioned at the data of the view data of lower layer side to the permeability of upper layer side view data.For example, if R, G, B data for the upper layer side view data are applied with the form of factor alpha, then R, G, the B data for the lower layer side view data are applied with the form of coefficient (1-α), lower layer side view data (not seeing through) when this value is 255, in composograph, do not occur, when this value is 0, in composograph, occur lower layer side view data (seeing through) fully.By with the arbitrary value in 0～255 the scope, can access the decorative effect of semi-transparent mistake.
Then, CPU200 obtains selected photographed images data GD, temporarily is stored in (step S110) among the RAM201.The selection of photographed images data GD for example, also can be carried out on digital still video camera 10, perhaps, also can be on personal computer 20 carries out through keyboard etc.Generally, as stating, the decorative picture data FD that selects (decision) to use follows, and selection will be configured in the photographed images data GD on each allocation position of decorative picture data FD.
Photographed images data GD for example, as shown in Figure 6, also can form 1 photographed images file GF with image processing control information GI.Image processing control information GI records and narrates in the time of both can having worked as photographed images data GD and have header cell in header cell, further, also can associate by the 3rd associated data and photographed images data GD.
CPU200, the decorative picture data FD that parsing obtains makes the histogram (step S120) of quality distribution character.Specifically, with pixel unit or with suitable pixel separation, scanning constitutes the view data of decorative picture data FD, makes histogram about each composition of R, G, B.CPU200 calculates representative color Fc (step S130) from the histogram of the decorative picture data FD that makes.Specifically, with the histogram that makes each R, G, B composition are tried to achieve the representative color Fc (Rm, Gm, Bm) of median (median) as the decorative picture data FD of this combination.The example of representative color Fc (Rm, Gm, Bm) for example, when 8 tonal gradations, can be got 0～255 value respectively as shown in Figure 7.Also can replace the mean value of median with R, G, each composition of B again.
The photographed images data GD that the CPU200 parsing obtains makes the histogram (step S140) of photographed images data GD.Specifically, CPU200 constitutes photographed images data GD with pixel unit scanning, obtains the image statistics value (image quality characteristics parameter value) of the characteristic of expression photographed images data GD.As the image quality characteristics parameter value, generally for example, try to achieve value, try to achieve the parameter related in the present embodiment with the color balance degree about the parameter of contrast, definition (sharpness), lightness (brightness) and so on, that is, about the histogram of R, G, each composition of B.
In order to determine the color balance degree to resolve correcting value Gc, when photographed images data GD is related with image processing control information GI foundation, also can be implemented with image processing control information GI.When as image processing control information GI, record and narrate the image quality characteristics parameter value relevant and the minimizing degree of the deviation between the benchmark image mass parameter value with the color balance degree, during the suitable level of automated graphics quality adjustment amount, replace predefined minimizing degree to determine according to minimizing degree by image processing control information GI regulation.On the other hand, when as image processing control information GI, when recording and narrating the occurrence of the image quality characteristics parameter relevant, the value of recording and narrating is resolved correcting value Gc as the color balance degree with the color balance degree.When with image processing control information GI, can be as the parsing correcting value of the intention that reflects shooting person.
CPU200 calculates color balance degree correction correcting value Mc (Rc, Gc, Bc) (step S160) from representative color Fc and color balance degree parsing correcting value Gc.Specifically, as follows.
(1) when Rm＞Gm, Bm (red strong decorative picture data FD), utilizes according to formula
(1) I that obtains tries to achieve correction k from the curve chart of Fig. 8,
I＝(Rm-(Gm+Bm)/2)/Rm (1)
Utilize formula (2) to revise the R composition that the color balance degree is resolved correcting value Gc (Ra, Ga, Ba), obtain color balance degree correction correcting value Mc (Rc, Gc, Bc).In addition, 0≤k≤0.4.
Rc＝Ra(1+k) (2)
Mc(Rc、Gc、Bc)＝(Ra(1+k)、Ga、Ba)
By the modification method of this correcting value, R becomes to be divided into some overcorrects, and as the color balance degree of whole photographed images data GD, R composition (red composition) weakens, the result, and G, B composition strengthen.Fig. 9 with this method of diagram at length describes.Determine the color balance degree to resolve correcting value Gc in the mode that when the R composition is strong, makes the R composition weaken (making fiducial value), make correcting value=0 about G, B composition near the R composition.If according to above-mentioned formula (2), then because only make and resolve correcting value Gc about the color balance degree of the R composition of such decision and further increase, so as a result of, the R composition further weakens.So, the decorative picture data FD strong to the R composition, color contrast strengthens, and as the output result, can access the output image that photographed images does not incorporate decorative picture.
(2) when Gm＞Rm, Bm (green strong decorative picture data FD), utilize according to formula
(3) I that obtains tries to achieve correction k from the curve chart of Fig. 8,
I＝(Gm-(Rm+Bm)/2)/Gm (3)
Utilize formula (4), (5) to revise the R composition that the color balance degree is resolved correcting value Gc (Ra, Ga, Ba), obtain color balance degree correction correcting value Mc (Rc, Gc, Bc).In addition, 0≤k≤0.4.
Rc＝Ra(1-k) (4)
Bc＝Ba(1-k) (5)
Mc(Rc、Gc、Bc)＝(Ra(1-k)、Ga、Ba(1-k))
By the modification method of this correcting value, the correcting value of R, B composition reduces, and as the color balance degree of whole photographed images data GD, R, B composition strengthen, and relatively, G composition (green composition) weakens.So, the decorative picture data FD strong to the G composition, color contrast strengthens, and as the output result, can access the output image that photographed images does not incorporate decorative picture.
(3) when Bm＞Rm, Gm (blue strong decorative picture data FD), utilize according to formula
(6) I that obtains tries to achieve correction k from the curve chart of Fig. 8,
I＝(Bm-(Rm+Gm)/2)/Bm (6)
Utilize formula (7) to revise the R composition that the color balance degree is resolved correcting value Gc (Ra, Ga, Ba), obtain color balance degree correction correcting value Mc (Rc, Gc, Bc).In addition, 0≤k≤0.4.
Bc＝Ba(1+k) (7)
Mc(Rc、Gc、Bc)＝(Ra、Ga、Ba(1+k))
By the modification method of this correcting value, B becomes to be divided into some overcorrects, and as the color balance degree of whole photographed images data GD, B composition (blue composition) weakens, the result, and R, G composition strengthen.So, the decorative picture data FD strong to the B composition, color contrast strengthens, and as the output result, can access the output image that photographed images does not incorporate decorative picture.
CPU200 implements the picture quality adjustment with the color balance degree correction correcting value Mc that calculates to photographed images data GD and handles (step 170).For example, use and the input level of the RGB composition of photographed images data GD and output level are set up corresponding tint ramp (S curve) implement the picture quality adjustment.When adjusting picture quality, color balance degree correction correcting value Mc (Rc, Gc, Bc) is used for each tint ramp of change (skew) R, G, each composition of B with tint ramp.Specifically, on tint ramp, about each image quality parameter, the point of revising correcting value is used in sample plot decision, in the situation of color balance degree for example, the side-play amount of the output level when using color balance degree correction correcting value Mc as input level 0.As a result, passing through a little of the tint ramp of change in this point makes the input-output characteristic change.So, if to photographed images data GD, use after changing R, G, each tint ramp of B, then each composition about the RGB of photographed images data GD carries out the input-output conversion, has obtained adjusting the photographed images data GD of picture quality.In addition, when in image processing control information GI, if when specifying intentional color seepage (color seepage), the automatic adjustment of the preferred unreal bedye degree of balance.In addition, in the picture quality adjustment is handled, also can change color balance degree correction correcting value Mc (Rc, Gc, Bc) by user's decision.The user, for example, through the input unit of personal computer, the guidance panel of color printer 30, Mc revises to color balance degree correction correcting value.
CPU200 according to synthetic (coincidence) decorative picture data FD of layout control information LI and photographed images data GD, generates output image data (step S180).For example, carry out as follows photographed images data GD synthesizing decorative picture data FD.
CPU200, explanation is about the allocation position recorded and narrated in layout control information LI and the script file of configuration sized, according to allocation position and the configuration sized of explanation results decision photographed images data with respect to decorative picture data FD, again, according to the gray-level value of α channel data decision decorative picture data FD, synthetic (coincidence) two view data.CPU200, adjusts the size of (dwindle or amplify) photographed images data according to the configuration sized of each allocation position of recording and narrating in the script file.
The synthetic processing of two images that undertaken by CPU200 for example, can be added up R, G, the B value of photographed images data by the value of using the α channel data of having stated, and R, the G, the B value that obtain output image data are implemented.Promptly, by about the zone of photographed images in output image (synthetic after image), occurring, do not hinder the mode of reproducing photographed images data GD with decorative picture data FD, make that the α channel data is 0, about the zone (decorative zones of decorative picture in output image, occurring, the frame zone), makes that the α channel data is 255, do not allow to reproduce photographed images.
CPU200 outputs to printer driver, display driver (step S190) with output image data, finishes this handling procedure.In printer driver, implement RGB-CMYK look conversion process, halftone process etc. with look-up table etc., for example, output image data is outputed to printer 30 as the raster data of attaching print control command.
As described above, according to personal computer 20 as the image processing apparatus relevant with the 1st embodiment, can judge the tendency of the color and taste of whole decorative picture data FD from the look distribution of decorative picture data FD, correction is resolved correcting value Gc by the color balance degree that the parsing that is configured in the photographed images data GD among the decorative picture data FD obtains, and can access color balance degree correction correcting value Mc.So, by so that the different mode of color and taste (tendency of look) of the color and taste of decorative picture data FD (tendency of look) and photographed images data GD, decision color balance degree correction correcting value Mc, the photographed images in the time of can making output and the colour contrast of decorative picture increase, can access with respect to decorative picture the output result that photographed images is eye-catching.
Again, in above-mentioned the 1st embodiment, CPU200 tries to achieve the color balance degree according to the analysis result of photographed images data GD and resolves correcting value Gc, the representative color Fc of reflection decorative picture data FD, the color balance degree that correction is tried to achieve is resolved correcting value Gc, decision color balance degree correction correcting value Mc uses the color balance degree correction correcting value Mc that is determined, implements the picture quality adjustment and handles.So distribute both picture quality adjustment of the look that can finish to consider the characteristic of photographed images data GD and decorative picture data FD in 1 time is handled.As a result, can not make the deterioration of image quality of the photographed images data GD after the processing, can shorten the time that the picture quality adjustment is handled to be needed.
In addition, in above-mentioned the 1st embodiment, by resolving decorative picture data FD, the look of trying to achieve decorative picture data FD distributes, i.e. representative color Fc, but also can be with the representative color Fc that in layout control information LI, stipulates in advance as representative color information shown in Figure 5.Further, also can in layout control information LI, stipulate correction k.In this case, can skip the dissection process of decorative picture data FD, can be promptly the photographed images data GD of the look characteristic of reflection decorative picture data be implemented the picture quality adjustment and handle.
Variation:
(1) in above-mentioned the 1st embodiment, only photographed images data GD is implemented the picture quality adjustment processing of color balance degree, but in addition, for example, about shade (shadowing), highlighted (highlighting), each picture quality that lightness (brightness), contrast, memory colour are proofreaied and correct is adjusted parameter, obviously also can implement the picture quality adjustment and handle.Can be enough the input level of the RGB composition of photographed images data GD and output level being set up corresponding tint ramp (S curve) implements these picture qualities are adjusted the picture quality adjustment of parameters and handles.Specifically, on tint ramp, about each image quality parameter, the point of revising correcting value is used in the sample plot decision, revises correcting value by using, and passing through a little of the tint ramp of change in this point makes the input-output characteristic change.So, if to photographed images data GD, use after changing R, G, each tint ramp of B, then each composition about the RGB of photographed images data GD carries out the input-output conversion, has obtained adjusting the photographed images data GD of picture quality.
(2) in the 1st embodiment, try to achieve the color balance degree and resolve correcting value Gc, the representative color Fc of reflection decorative picture data FD tries to achieve color balance degree correction correcting value Mc, at last photographed images data GD is practiced the picture quality adjustment processing of color balance degree correction correcting value Mc, but also can followingly implement.
Also can be in the moment of trying to achieve color balance degree parsing correcting value Gc, photographed images data GD is practiced the 1st picture quality adjustment processing that the color balance degree is resolved correcting value Gc, make photographed images data GD standardization, then, according to the representative color Fc of decorative picture data FD, photographed images data GD is implemented the picture quality adjustment handle.In this case, with after fiducial value is consistent,, can implement to reflect that the picture quality adjustment that the look of decorative picture data FD distributes handles in the picture quality that makes photographed images data GD perhaps near after the fiducial value.
The 2nd embodiment:
With reference to the image processing that Figure 10～Figure 14 explanation is implemented in the personal computer 20 relevant with the 2nd embodiment.Figure 10 is the flow chart that is illustrated in the handling procedure of the image processing of implementing in the personal computer 20 relevant with the 2nd embodiment.Figure 11 is the key diagram of the file structure of the pattern ground expression decorative picture file FF that possesses decorative picture data FD and layout control information LI.Figure 12 is the key diagram that an example of the light characteristic that the result of decorative picture data FD obtains is resolved in expression.Figure 13 is the key diagram that an example of the light characteristic that the result of photographed images data GD obtains is resolved in expression.Figure 14 is the key diagram of expression to the relation of the input value of lightness correction correcting value γ and output valve.In addition, the vivid example of decorative picture data FD is the example that is illustrated in the state when launching on the frame buffer conceptually.Again, because the image processing apparatus (personal computer) relevant with the 2nd embodiment possesses and the image processing apparatus same formation relevant with the 1st embodiment, so the additional identical label of identical formation is also omitted its explanation.
The image processing that explanation is implemented in the 2nd embodiment with reference to Figure 10.The image processing of Shi Shiing in the present embodiment, for example, both can work as when being installed in storage card MC in the personal computer 20, perhaps, when being connected with personal computer 20 through telecommunication cable, digital still video camera 10 begins, perhaps, also can work as when carrying out image processing by user's indication and implement through keyboard etc.
Personal computer 20 (CPU200) when the beginning image processing, is obtained selected decorative picture data FD, temporarily is stored in (step S200) among the RAM201.The selection of decorative picture data FD for example, also can be carried out on digital still video camera 10, perhaps, also can be on personal computer 20 from be stored in the decorative picture data the HDD202 in advance, select, perhaps, also can select through network through keyboard etc.In addition, decorative picture data FD is in order to dispose a plurality of photographed images data GD, also can have a plurality of allocation positions, in the present embodiment, for the purpose of easy explanation, explanation is attached to situation among the decorative picture data FD with 1 allocation position with single (1) photographed images data GD.
Decorative picture data FD, for example, (when frame buffer launches) has form shown in Figure 4 when output image, is ready to the allocation position that one or more are used to attach photographed images data GD.
In the form of the decorative picture file FF that possesses decorative picture data FD and layout control information L1, handle decorative picture data FD.Decorative picture file FF, for example, possesses file structure shown in Figure 11, the allocation position information that layout control information L1 regulation will dispose photographed images data GD (for example, and the configuration sized (adjustment size) of the photographed images data GD in the specified configuration position, further also can stipulate the look distribution character information of decorative picture data FD coordinate information).
Further the α channel data is recorded and narrated in layout control information L1.The α channel data, for example, be (for example relatively to adjust view data that image is positioned at upper layer side when synthetic, decorative picture data FD) and the view data that is positioned at lower layer side (for example, photographed images data GD) in each gray-level value (R, G, B data value), is used to determine to be positioned at the data of the view data of lower layer side to the permeability of upper layer side view data.For example, if R, G, B data for the upper layer side view data are applied with the form of factor alpha, then R, G, the B data for the lower layer side view data are applied with the form of coefficient (1-α), lower layer side view data (not seeing through) when this value is 255, in composograph, do not occur, when this value is 0, in composograph, occur lower layer side view data (seeing through) fully.By with the arbitrary value in 0～255 scope, can access the decorative effect of semi-transparent mistake.
Then, CPU200 obtains selected photographed images data GD, temporarily is stored in (step S210) among the RAM201.The selection of photographed images data GD for example, also can be carried out on digital still video camera 10, perhaps, also can be on personal computer 20 carries out through keyboard etc.Generally, as stating, the decorative picture data FD that selects (decision) to use follows, and selection will be configured in the photographed images data GD on each allocation position of decorative picture data FD.
Photographed images data GD for example, as shown in Figure 6, also can form 1 photographed images file GF with image processing control information GI.Image processing control information GI records and narrates in the time of both can having worked as photographed images data GD and have header cell in header cell, further, also can associate by the 3rd associated data and photographed images data GD.
The decorative picture data FD that the CPU200 parsing obtains makes the histogram (step S220) of light characteristic.Specifically, with pixel unit or with suitable pixel separation, scanning constitutes a plurality of pixel datas of decorative picture data FD, makes histogram about brightness (luminance) composition.CPU200 calculates mean flow rate Yfm (step S230) from the histogram of the decorative picture data FD that makes.Specifically, try to achieve the median (median) of brightness Yf with the histogram that makes.The example of histogram, mean flow rate Yfm for example, when 8 tonal gradations, can be got 0～255 value as shown in figure 12.Also can replace the mean value of median about each pixel data again.
The photographed images data GD that the CPU200 parsing obtains as shown in figure 13, makes the histogram (step S240) of the light characteristic of photographed images data GD.Specifically, CPU200 obtains the image statistics value (image quality characteristics parameter value) of the characteristic of expression photographed images data GD with pixel unit scan camera shooting view data GD.As the image quality characteristics parameter value, generally for example, try to achieve value about the parameter of contrast, definition, color balance degree and so on, try to achieve the parameter related in the present embodiment with lightness, that is, and about the histogram of brightness composition.
Gy＝Ygm/Ys
In the formula, Ys is a benchmark image mass parameter value.
In order to determine lightness to resolve correcting value Gy,, also can be implemented with image processing control information GI when photographed images data GD and image processing control information GI establish when related.When as image processing control information GI, when having recorded and narrated the suitable level of minimizing degree, automated graphics quality adjustment amount of the deviation between image quality characteristics parameter value relevant and the benchmark image mass parameter value, replace predefined minimizing degree according to resolving correcting value Gy by the minimizing degree decision lightness of image processing control information GI regulation with brightness.On the other hand, irrelevant when having recorded and narrated the occurrence with the image quality characteristics parameter of brightness when as image processing control information GI with the analysis result of photographed images data GD, the value of recording and narrating is resolved correcting value Gy as lightness.When with image processing control information GI, can be as the parsing correcting value of reflection shooting person intention.
CPU200 calculates lightness correction correcting value (correction coefficient) γ (step S260) from mean flow rate Ymf and lightness parsing correcting value Gy.Specifically, as follows.
DY＝(Yfm-Th)·k (8)
In the formula, Th is the threshold value that the light and shade of decorative picture data FD is judged, k is a constant, and k is big more, and the lightness contrast is big more.
γ＝Gy+DY/Th (9)
By the modification method of this correcting value, when Ym＞Th, that is, when decorative picture data FD is bright,,, proofreaies and correct photographed images data GD and make its deepening so as shown in figure 14 for input value, output valve reduces because lightness correction correcting value γ further increases.On the other hand, when Ym＜Th, that is, when decorative picture data FD is dim,,, proofreaies and correct photographed images data GD and make it bright so as shown in figure 14 for input value, output valve increases because lightness correction correcting value γ reduces.
CPU200 implements the picture quality adjustment with the lightness correction correcting value γ that calculates to photographed images data GD and handles (step S270).Picture quality is adjusted, and for example, as shown in figure 14, uses and the input level of the RGB composition of photographed images data GD and output level are set up corresponding tint ramp (S curve) implements.Specifically, use same tint ramp as follows about R, G, each composition of B.
R′＝(R/255)
γ
G′＝(G/255)
γ
B′＝(B/255)
γ
As a result, carry out the input-output conversion, obtained adjusting the photographed images data GD of picture quality about R, the G of photographed images data GD, each composition of B.When lightness correction correcting value γ was bigger than lightness parsing correcting value Gy, because for input value, output valve reduced, so the lightness of photographed images data GD reduces (reduction).So the lightness contrast increases between the photographed images data GD of bright decorative picture data FD and dimness, when output, photographed images does not incorporate decorative picture, can make photographed images eye-catching.
On the other hand, when lightness correction correcting value γ resolved correcting value Gy hour than lightness, because for input value, output valve increases, so the lightness of photographed images data GD increases (rising).So the lightness contrast increases between the decorative picture data FD of dimness and bright photographed images data GD, when output, photographed images does not incorporate decorative picture, can make photographed images eye-catching.In addition, in the picture quality adjustment is handled, also can change determined lightness correction correcting value γ by the user.The user for example, through the input unit of personal computer, the guidance panel of color printer 30, revises lightness correction correcting value γ.
When the picture quality adjustment of the lightness of photographed images data GD was finished dealing with, CPU200 was according to synthetic (coincidences) decorative picture data FD of layout control information LI and photographed images data GD, generation output image data (step S280).Photographed images data GD is synthetic to decorative picture data FD's, for example, carries out as follows.
CPU200 explains about the allocation position of recording and narrating in layout control information LI and the script file of configuration sized, according to allocation position and the configuration sized of explanation results decision to the photographed images data of decorative picture data FD, again, according to the gray-level value of α channel data decision decorative picture data FD, synthetic (coincidence) two view data.CPU200 is according to the configuration sized of each allocation position of recording and narrating in the script file, adjusts the size of (dwindle or amplify) each photographed images data.
The synthetic processing of two view data of being undertaken by CPU200 for example, can be added up R, G, the B value of each photographed images data by the value of using the α channel data of having stated, and R, the G, the B value that obtain output image data are implemented.Promptly, by about the zone of photographed images in output image (synthetic after image), occurring, do not hinder the mode of reproducing photographed images data GD with decorative picture data FD, make that the α channel data is 0, about the zone (decorative zones of decorative picture in output image, occurring, the frame zone), makes that the α channel data is 255, do not allow to reproduce photographed images.
CPU200 outputs to printer driver, display driver (step S290) with output image data, finishes this handling procedure.In printer driver, implement RGB-CMYK look conversion process, halftone process etc. with look-up table etc., for example, output image data is outputed to printer 30 as the raster data of attaching print control command.
As described above, according to personal computer 20 as the image processing apparatus relevant with the 2nd embodiment, can judge the tendency of the lightness of decorative picture data FD from the Luminance Distribution of decorative picture data FD, correction is resolved correcting value Gy by the lightness that the parsing that is configured in the photographed images data GD among the decorative picture data FD obtains, and can access lightness correction correcting value γ.So, by so that the different mode of brightness (tendency of lightness) of the brightness of decorative picture data FD (tendency of lightness) and photographed images data GD, decision lightness correction correcting value γ, the photographed images in the time of can making output and the lightness contrast of decorative picture increase, can access with respect to decorative picture the output result that photographed images is eye-catching.
Again, in above-mentioned the 2nd embodiment, CPU200 tries to achieve lightness according to the analysis result of photographed images data GD and resolves correcting value Gy, the mean flow rate Yfm of reflection decorative picture data FD, the lightness that correction is tried to achieve is resolved correcting value Gy, decision lightness correction correcting value γ uses the lightness correction correcting value γ that is determined, implements the picture quality adjustment and handles.So, can finish in 1 time to consider that the picture quality adjustment of the brightness of the characteristic of photographed images data GD and decorative picture data FD is handled.As a result, can not make the deterioration of image quality of the photographed images data GD after the processing, can shorten the time that the picture quality adjustment is handled to be needed.
In addition, in above-mentioned the 2nd embodiment,, try to achieve the light characteristic of decorative picture data FD by resolving decorative picture data FD, be mean flow rate Yfm, but also can be with the information of the mean flow rate Yfm that in layout control information LI, stipulates in advance as light characteristic shown in Figure 5.Further, also can in layout control information LI, stipulate correction DY/Th.In this case, can skip the dissection process of decorative picture data FD, can be promptly the photographed images data GD of the light characteristic of reflection decorative picture data be implemented the picture quality adjustment and handle.
