Abstract
An image processing apparatus in the present disclosure includes a color conversion processing unit, a modulation candidate creating unit, a color value modulating unit, and an output unit. The color conversion processing unit performs color conversion from an input color value of a target image to a corresponding output color value to obtain a tentative output color value. The modulation candidate creating unit creates, as modulation candidates, combinations of integer values obtained by rounding up or down the decimal fraction of each color component of a tentative output color value. The color value modulating unit selects a modulation candidate at random and performs modulation by replacing the tentative output color value with the selected modulation candidate. The output unit outputs the target image according to the color value obtained after the modulation.

（First embodiment）
Fig. 2 is the functional block diagram for representing the image processing apparatus that the first embodiment of the present invention is related to.Such as Fig. 1 and figure
Shown in 2, control unit 11A of present embodiment includes color conversion processing unit 110 and colour modulating unit 111.Color turns
Change processing unit 110 the input colour color of object images to be converted into corresponding output colour and is come as interim output colour
Obtain.Colour modulating unit 111 is carried out for interim output colour according to each color component for constituting the interim output colour
By its fractional value, randomly carry or the mantissa given up the throne are processed, and are thus modulated.
Color conversion processing unit 110 is included from RGB to CMYK converting units 1100.From RGB to CMYK converting units
1100 by the colour with each pixel of input picture（Rgb value）Colour of the corresponding color to the output form that can be reproduced
（CMYK values）Carry out color conversion.Specifically, include in advance from RGB to CMYK converting units 1100 by with rgb value and
The suitable lattice point of mapping of CMYK values is being presented the latticed LUT of three-dimensional orthogonal（Look Up Table, look-up table）.Then, lead to
Cross with reference to the LUT, the rgb value color of subject pixels is converted into into corresponding CMYK values.For the RGB of the coordinate positioned between lattice point
Value, corresponding CMYK values are obtained by known interpolation arithmetic.
In addition, carrying out fractional value definition to CMYK values involved between each lattice point and lattice point, and do not carry out the tail of fractional value
Number is processed or integer definition.
In addition, the output colour that will be also carried out after the conversion of the color of modulation（CMYK values）Colour is referred to as exported temporarily
（Temporary transient CMYK values）.
Colour modulating unit 111 include final CMYK values candidate signal generating unit 1110, final CMYK values setup unit 1111,
Random number generation unit 1112 and modulation extra switch 1113.
Final CMYK value candidate signal generating units（Modulation candidate signal generating unit）1110 will be according to the interim output color of each composition
The color component of value enters to be about to its fractional value carry or its integer-valued each group cooperation for giving up the throne and constituting and comes for modulation candidate
Generate.
For example, in the case of interim output colour { C, M, Y, K }={ 125.5,133.2,234.8,58.1 }, by its point
Into integer part { 125,133,234,58 } and fractional part { 0.5,0.2,0.8,0.1 }.Obtain for C, M, Y, it is each in K
It is individual the value carry of fractional part to be added 1 to the value of integer part or the value of fractional part is given up the throne and is kept original whole
The combination of the value of fractional part.As a result, generating following 24The modulation candidate of=16 species.
{ 125,133,234,58 }, { 125,133,234,59 }, { 125,133,235,58 }, { 125,133,235,59 },
125,134,234,58 }, { 125,134,234,59 }, { 125,134,235,58 }, { 125,134,235,59 }, 126,133,
234,58 }, { 126,133,234,59 }, { 126,133,235,58 }, { 126,133,235,59 }, { 126,134,234,58 },
126,134,234,59 }, { 126,134,235,58 }, { 126,134,235,59 }
Alternatively, it is also possible to the carry for not carrying out fractional value and the ambilateral process given up the throne, but carry value is only obtained, and
Other modulation candidates are obtained by subtracting " 1 " from the value.Alternatively, it is also possible to only obtain value of giving up the throne, and by adding " 1 " to the value
To obtain other modulation candidates.
Final CMYK value candidates signal generating unit 1110 preserves generated modulation candidate.
Final CMYK value setup units（Colour modulating unit）1111 by final CMYK values candidate signal generating unit 1110 from being given birth to
Into modulation candidate in be randomly chosen one modulation candidate.Then, final CMYK values setup unit（Colour modulating unit）
1111 are modulated by replacing interim output colour and selected modulation candidate.
For example, numerical value or numerical range and the institute of the random number that can be produced by random number generation unit 1112 are pre-saved
State the corresponding relation of the modulation candidate of 16 species.Obtain from the corresponding relation currently available with by random number generation unit 1112
The corresponding modulation candidate of random number, and interim output colour is replaced with into the modulation candidate.
As a result, original interim CMYK values are individually increased by one or are kept its integer-valued value with C, M, Y, K
It is exported to output unit 12.
Output unit 12 carries out the output of object images based on the colour after modulating by this way.
Modulation extra switch 1113 is made whether the setting to be modulated according to the setting operation of user.
Modulation extra switch 1113 to final CMYK values setup unit 1111 exports setting signal.
If the meaning not being modulated is input into final CMYK values setup unit 1111 from modulation extra switch 1113
Signal, then non-modulated original interim CMYK values be directly exported to output unit 12.Final CMYK values candidate generates single
Unit 1110 can also be controlled to realize the function in the way of not generating and modulate candidate.
In this case, colour modulating unit 112 is not modulated, and output unit 12 is carried out based on interim output colour
The output of object images.
It is such be formed in cannot effectively be modulated in the case of be convenient.It is so-called to be effectively modulated
Situation refer to：For example, therefore it is not envisaged that even if false contouring does not occur etc., do not have the advantages that to sacrifice what image quality to be also modulated
Situation, it is undesirable to because identical colour becomes the situation of the reduction of discontinuous and caused compression ratio.
As described above, the interim CMYK values of the image processing apparatus involved by the first embodiment of the present invention 1 pair, according to every
Individual C, M, Y, K enter to be about to its fractional value randomly carry or the mantissa given up the throne process to replace colour, thus to interim CMYK
Value is modulated.
Therefore, export colour and be changed into trickle and irregular colour, therefore, it is possible to be effectively prevented due to identical colour
The generation of continuous and caused false contouring.
Further, since the modulation of colour is carried out based on the value suitable with the minimum resolution of output colour, therefore, it is possible to
Solve the problems, such as the balance that the another aspect image quality of the generation for preventing false contouring is reduced.
According to image processing apparatus of the present embodiment 1, puppet can also be effectively prevented while image quality is kept
The generation of profile.
（Second embodiment）
Then, the image processing apparatus 1 being related to second embodiment of the present invention are illustrated.Fig. 3 is this embodiment party
The functional block diagram of the image processing apparatus that formula is related to.
As shown in figure 3, in the image processing apparatus 1 of present embodiment, control unit 11B is same with first embodiment
Ground includes color conversion processing unit 110 and colour modulating unit 111.Control unit 11B of present embodiment also includes decimal
Part comparing unit 1114.
Colour modulating unit 111 includes：Integer part/fractional part separative element 1110, final CMYK values setup unit
1111st, random number generation unit 1112, modulation extra switch 1113 and fractional part comparing unit 1114.
Integer part/fractional part separative element 1110 separates the integer part and fractional part of interim output colour.So
Afterwards, integer part is exported to final CMYK values setup unit 1111, fractional part is defeated to fractional part comparing unit 1113
Go out.
Random number generation unit 1112 is by contained numerical value in the range of 0～1（Fractional value）Randomly and as at this
In the range of substantially uniform random number producing.Each pixel for example for the object as modulation produces random number, and
The numerical value of the random number being sequentially generated according to each C, M, Y, K is exported to fractional part comparing unit 1114.
Fractional part comparing unit 1114, compares from the interim defeated of integer part/input of fractional part separative element 1110
Go out the value of the fractional part of colour（Fractional value）With the random number produced by random number generation unit 1112.Then, interim defeated
In the case of going out value of the fractional value of colour more than random number, to the output of final CMYK values setup unit 1111 fractional value is moved back
The instruction of the meaning of position.In the case where the fractional value of interim output colour is below the value of random number, set to final CMYK values
The output of order unit 1111 makes the instruction of the meaning of the fractional value carry.
Final CMYK values setup unit 1111 is according to the instruction being input into from fractional part comparing unit 1114, and modulation is interim defeated
Go out colour.Specifically, according to the instruction of " meaning of carry ", be modulated into by the value of the fractional value carry of interim output colour,
The value for adding 1 to the integer value of interim output colour.On the other hand, according to the instruction of " meaning given up the throne ", being modulated into will be interim
The integer value for export the fractional value of the colour value given up the throne, exporting colour temporarily.
Respectively for C, M, Y, K carries out such carry or the process given up the throne, therefore actually from the tune of 16 species
Any one is selected to be modulated in candidate processed.
For example, it is { C, M, Y, K }={ 125.5,133.2,234.8,58.1 } to the interim output colour of subject pixels
The modulation treatment of situation is illustrated.
In this case, integer part is { 125,133,234,58 }, and fractional part is { 0.5,0.2,0.8,0.1 }.
In addition, in this example embodiment, as with C, the corresponding random number of M, Y, K and obtain 0.11,0.82,0.45,0.61.
Due to C（Cyan）Interim output colour fractional value（0.5）More than the value of random number（0.11）, therefore make decimal
Value is given up the throne, and becomes C=125.
If for M（Magenta）、Y（Yellow）、K（Black）Same process is also carried out, then M=134, Y=234, K=
59。
As a result, the interim CMYK values { 125.5,133.2,234.8,58.1 } of object be modulated into 125,134,
234,59 }.
Alternatively, it is also possible to not be to obtain random number according to each channel as described above, but for the picture of object
Element, each channel carries out carry or the judgement given up the throne on the basis of same random number.
Here, illustrate for identical colour（Comprising fractional value）The continuous situation for partly carrying out such modulation treatment
Effect.
As an example, illustrate to interim output colour { C, M, Y, K }={ 125.5,133.2,234.8,58.1 }
The situation that the region that continuous pixels are 100 is modulated.
In this case, 100 randoms number suitable with the continuous pixel count are obtained.Each random number is to will be contained in
What the fractional value in the range of 0～1 was substantially evenly produced within the range.In the above example, the interim output colour of K by
In the fractional value be 0.1, therefore the probability with random number more than 0.1（（1-0.1）/ 1=90%）Given up the throne, so as to carry out
Modulation.
Thus, compared with the situation for only being rounded up to modulate to fractional value, false contouring can be more efficiently prevented from.
For example, in the above example, the K if it is assumed that rounding up fractional value to be modulated, in 100 contiguous pixels
Value is given up the throne without exception, and the colour after modulation is all changed into identical value（K=58）.But, according to present embodiment, in 100 companies
In K values in continuous pixel, 90 are given up the throne, 10 pixel quilts by carry, the pixel of the colour of K=58 and the colour of K=59
Spread.
Therefore, according to the modulation treatment of present embodiment, especially, even if in colour in fractional value level identical picture
In the case of element is continuous, it is also possible to effectively prevent the generation of false contouring.
Modulation extra switch 1113 is made whether the setting to be modulated according to the setting operation of user.This with it is aforesaid
Embodiment one is identical.
So, the image processing apparatus 1 being related to second embodiment of the invention, are carried out such as modulated：Make interim
CMYK values become C, the integer of the fractional value of the output colour of M, Y, K based on probability carry corresponding with the value or after giving up the throne
Value.Therefore, export colour and be changed into trickle and irregular colour, be prevented from due to the continuous and caused false ring of identical colour
Wide generation.
Further, since the modulation of colour is carried out based on the value suitable with the minimum resolution of output colour, therefore, it is possible to
Solve the problems, such as the balance that image quality is reduced while the generation of false contouring is prevented.According to image procossing of the present embodiment
Device 1, can also be effectively prevented the generation of false contouring while image quality is kept.

Alternatively, it is also possible to the control signal for including identification information is exported to final CMYK values candidate signal generating unit
1110.In this case, final CMYK values candidate signal generating unit 1110 only generates the modulation candidate of selected channel, only right
Specific channel is modulated.
For example, in the case where have selected first mode, final CMYK values candidate signal generating unit 1110 is only carried out to K channels
By the fractional value carry of interim CMYK values or process of giving up the throne, and modulation time is generated as by integer-valued one group of interim CMYK values
Mend.As a result, generating the modulation candidate of 2 following species.{ 125,133,234,58 }, { 125,133,234,59 }
In addition, in the case where have selected second mode, final CMYK values candidate signal generating unit 1110 is only to C, and M's, Y is each
Channel enters the fractional value carry or process of giving up the throne for being about to interim CMYK values, and integer-valued one group of interim CMYK values is generated as
Modulation candidate.As a result, generating following 23The modulation candidate of=8 species.
{ 125,133,234,58 }, { 125,133,235,58 }, { 125,134,234,58 }, { 125,134,235,58 },
126,133,234,58 }, { 126,133,235,58 }, { 126,134,234,58 }, { 126,134,235,58 }
Final CMYK values setup unit 1111 is randomly chosen one and modulates candidate from these modulation candidates, by should
