Description

Image data generating device and image-data generating method
Technical field
In the body paper that the present invention relates in porous printing, use (master) plate-making; Perhaps in the printing equipment beyond ink-jet printer, laser printer, generate image data generating device and image-data generating method that expression is recorded in the view data of the image on the recording medium.
Background technology
All the time, as one of printing equipment, use hole plate print device.In this hole plate print device,, obtain the binaryzation data through after view data being carried out predetermined picture processing and pixel value conversion process, carrying out binaryzation.The first limit of heat is according to the binaryzation data that obtained and local pyrexia, with sensible heat porous body paper contact and bore a hole on one side, thereby process body paper.Then, the perforated portion through made body paper makes China ink transfer to printed medium, thereby obtains printed article.
In this type of porous printer, when having beat portion (local lettering rate is 100% part) in the view data, the China ink amount of transferring to printed medium from body paper increases.When on this printed medium, discharging and during overlapping subsequently recording medium, the China ink on the last printed medium might be transferred to the back side of back one recording medium.When China ink when other printed mediums are transferred to the back side, this China ink can see through the front of printed medium and in sight, produces so-called " back of the body prints ", has the problem of press quality variation.
For solving this type of problem, patent document 1 and 2 disclosed technology are for example arranged.In this patent document 1 and 2 disclosed technology, the beat portion of recognition image data carries out sparse processing to the China ink amount of beat portion.Can reduce the generation of " back of the body seal " thus.
But; In patent document 1 and 2 disclosed technology; What carry out sparse processing is the beat portion of view data; Therefore can not suppress promptly, to make phenomenon fuzzy between fine rule because stain spread and sunk in by the fine rule of literal when " literal is fuzzy " that use the bigger printed medium of dot gain (dot gain) to be produced when printing thin word.
Especially, under the situation of bigger low pulp content printing of the inhomogeneous and black rate of the soaking into change of the arrangement of comparing the influence that is easy to receive dot gain, fiber with fine paper and size and mestha paper etc., be easier to take place " literal blurs ".In addition, especially, under the situation of the size of the literal below No. 10, stroke number Chinese character how etc., it is fuzzy that thin character segment literal often takes place, and has the low problem of repeatability of literal.
Also propose not sparse graph as the China ink amount of beat portion in the past, but when making view data, reduced to read the method for concentration, and the method for the squeegee pressure when reducing to print.And, in technical fields such as ink-jet printers, also proposed to extract the outline portion in the view data, the black drop of this part is replaced with droplet, perhaps make the sparse technology of number of drops (for example, patent document 3).
Patent document
Patent document 1: japanese kokai publication hei 5-22582 communique
Patent document 2: japanese kokai publication hei 5-22583 communique
Patent document 3: TOHKEMY 2002-292848 communique
But, reduce to read in the method for concentration above-mentioned, using single threshold value to make without exception under the situation that concentration reduces, produce blank at thin character segment.In addition, reduce concentration, can not avoid producing unfavorable conditions such as unclear at thin character segment even wait through the error diffusion processing.Therefore, read in the method for concentration reducing, have the problem of the repeatability that can't improve thin word.
In addition, adopting through reducing under body paper makes the method that printing concentration reduces to the squeegee pressure of printed medium the situation, though improved the repeatability of thin word, beat portion does not fill up, and produces blank.
In addition, in above-mentioned patent document 3 disclosed technology, the outline line that will extend along the specific direction on the original copy extracts etc. as characteristic quantity, extracts feature in the image wide part of detection wheel of assigning to, and carries out sparse processing.But under the situation of the view data that is read from original copy by for example scanner, the situation itself that the outline line in the view data extends along straight line is with regard to seldom.This be because, when the original copy that is read view data by scanner was printed, suitable sparse image data processed was carried out in short of use, the situation that the outline line of original copy is straight line shape clearly is just few.Therefore, even the technology of patent document 3 is used for the sparse processing of fine rule, also be difficult to obtain effective result.
Summary of the invention
The present invention makes in view of the above problems; Its purpose is to provide a kind of image data generating device and image-data generating method; When making it possible in printing equipments such as porous printing to generate expression and being recorded in the view data of the image on the recording medium, even for the printed medium of the stain that is easy to spread and sink in, the concentration ground that does not also reduce beat portion grades to the thin thread part of literal and carries out sparse processing reliably; Eliminate the fuzzy of word segment, thereby improve the repeatability of literal.
To achieve these goals, the present invention provides a kind of image data generating device, is used for generating the view data that expression is recorded in the image on the recording medium at printing equipment, comprising: binary conversion treatment portion, and it carries out binaryzation to the view data of being imported; The picture element density calculating part; It selects the pixel conduct in the view data after the binaryzation to gaze at pixel successively; The pixel quantity of calculating black pixel in a plurality of pixels that reference area comprised that comprise the said preset range of gazing at pixel calculates and the said picture element density of gazing at the corresponding said reference area of pixel according to the pixel quantity of said black pixel; Sparse rate calculating part, it is according to the picture element density that is calculated by said picture element density calculating part, and the definition of data of the picture element density of the said reference area of reference expression and the corresponding relation of sparse rate calculates the sparse rate for each pixel; And sparse handling part; Its basis and the corresponding pattern of said sparse rate; Reduce the sparse processing of the concentration of each pixel, the relation of said picture element density of definition and sparse rate in said definition of data, thereby in the picture element density scope higher than predetermined threshold; Picture element density increases then sparse rate more and reduces more, and lower than the sparse rate in the picture element density scope below the said predetermined threshold.
In foregoing invention, according to calculating the sparse rate of each pixel (respectively gazing at pixel) with the picture element density of gazing at the corresponding reference area of pixel.Therefore, according to the relation of gazing at the pixel picture element density peripheral, for example can judge that this gazes at pixel is beat portion or thin character segment, thereby can confirm sparse degree with it.Particularly, in the picture element density positions such as beat portion higher than predetermined threshold value, picture element density increases more then makes sparse rate descend more, thus concentration high more be difficult to more sparse.And, in the picture element density positions such as beat portion higher, be that positions such as thin character segment below the predetermined threshold value are compared with picture element density than predetermined threshold value, sparse rate is reduced.Like this, can not make the concentration of beat portion guarantee sparse at thin character segment with descending, thereby can eliminate the fuzzy of word segment, improve the repeatability of literal etc.
Especially, reference area comprises the pixel that contains the preset range of gazing at pixel, calculates the picture element density of reference area according to the quantity of the contained black pixel of this reference area.Therefore, decide sparse rate, sparse rate is changed through picture element density according to reference area.
For example; At reference area from pixels such as the position low density position of blank parts to the beat portion transition; To carry out sparse with the sparse rate of the corresponding degree of this picture element density; When reference area moves in beat portion from the profile of beat portion, along with increasing of picture element density sparse rate is descended step by step, sparse rate is changed.Its result even at profile of beat portion etc. rapid change in concentration can not take place yet, can carry out sparse smoothly.
And; In foregoing invention, after with the view data binaryzation, carry out the parsing of sparse rate, thereby can reduce data volume as the object of printing treatment; The burden that can realize printing treatment alleviates and high speed, and can realize the miniaturization and low priceization of arithmetic processing apparatus and storage device.
Also have, in foregoing invention, carry out under the situation with the calculating of the picture element density of gazing at the corresponding reference area of pixel at the picture element density calculating part, the content that the picture element density calculating part has according to view data changes the area of reference area or the function of shape.
In foregoing invention, change the area or the shape of reference area according to the content of view data.As the content of view data, for example, comprise font size and the font of the literal that view data is contained, the kind that literal is modified etc.Through change the area or the shape of reference area corresponding to these, can more correctly judge the relation of gazing at the pixel picture element density peripheral with it, can improve the precision of sparse processing.
As this reference area, be generally 5 * 5 pixel quantity and shape and get final product, still; For example, under the situation of No. 10 black face fonts, white pixel partly reduces and is easy to and blurs; Therefore, if calculate the picture element density of 7 * 7 reference area, the white pixel part is estimated lessly with respect to the ratio of reference area; The picture element density of this part increases, and can likewise adopt the countermeasure that makes degradation under the sparse rate with beat portion.
In foregoing invention, in definition of data, the sparse rate of the picture element density below the predetermined threshold value is defined as the specific higher limit less than 100%.
In foregoing invention; In low density positions of pixel such as for example thin character segments, be set to the upper limit through its sparse rate less than 100%, the blank ground that can not produce literal suitably carries out sparse; Can eliminate the fuzzy of word segment, thereby further improve the repeatability of literal etc.
In foregoing invention, above-mentioned specific higher limit is 50%, and above-mentioned sparse handling part makes the corresponding pattern of sparse rate with above-mentioned specific higher limit be whenever alternate grid-like at a distance from a pixel.
In foregoing invention; Even be positioned under the situation of position that sparse rate is a maximum pixel density at reference area; Through making specific higher limit is 50%; And sparse whenever to carry out at a distance from the alternate chequer of a pixel, also can not visual degree come suitably to carry out sparse with the blank of thin word.
In foregoing invention, also comprise: the binaryzation data store, it stores the view data that said binary conversion treatment portion has carried out binaryzation; And image selection portion; It is under the situation of predefined particular types in kind that obtains said recording medium and the kind that obtained; Read out in image stored data in the said binaryzation data store, the calculating of the sparse rate of the view data of in said sparse rate calculating part, carrying out being read.
In foregoing invention, can be only carry out above-mentioned sparse processing generating when China inks such as low pulp content printing or mestha paper are easy to spread and sink in the view data of the recording medium printing of steeping, and can as one man generate view data with the characteristic of recording medium.Especially; The view data of binaryzation is stored in the binaryzation data store when the view data that for example generates to plain paper, and the view data of binaryzation is read to be used for the computing of sparse processing according to the kind as the recording medium of the object of printing treatment.Because the data volume of binaryzation data is littler than common multi-value data, therefore can reduces storage area, and can realize the miniaturization and low priceization of storage device.
In other words; Because the view data of binaryzation is the view data to general plain paper; Therefore be the kind time-like that common paper etc. need not carried out sparse processing at recording medium, with this view data of binaryzation be used for general printing treatment and body paper plate-making processing, afterwards; In the binaryzation data store, preserve; At recording medium is the kind time-like that low pulp content printing or mestha paper etc. need carry out sparse processing, can read the view data of preserving in advance, it is changed carry out sparse processing.Its result; Not only can realize the miniaturization and low priceization of storage device; Also can realize the utilization again of binary image data; Thereby when in the plate-making of general printing treatment and body paper is handled, needing the view data of binaryzation, do not need all to be used to make the calculation process of the big multi-value data binaryzation of data capacity at every turn, can realize that the burden of printing treatment alleviates and high speed.
To achieve these goals; The present invention also provides a kind of image-data generating method; Be used for generating the view data that expression is recorded in the image on the recording medium, comprise at printing equipment: the binary conversion treatment step, it carries out binaryzation to the view data of being imported; The picture element density calculation procedure; It selects the pixel conduct in the view data after the binaryzation to gaze at pixel successively; The pixel quantity of calculating black pixel in a plurality of pixels that reference area comprised that comprise the said preset range of gazing at pixel calculates and the said picture element density of gazing at the corresponding said reference area of pixel according to the pixel quantity of said black pixel; Sparse rate calculation procedure, it is with reference to the definition of data of the corresponding relation of picture element density that defines said reference area and sparse rate, according to the picture element density of said picture element density calculation procedure calculating; Calculate sparse rate for each pixel; Wherein, said definition of data is following data, in the picture element density scope higher than predetermined threshold; Picture element density increases then sparse rate more and reduces more, and lower than the sparse rate in the picture element density scope below the said predetermined threshold; And sparse treatment step, the corresponding pattern of sparse rate that its basis and said sparse rate calculation procedure are calculated reduces the sparse processing of the concentration of each pixel.
According to the present invention; In printing equipments such as porous printing, generate when being illustrated in the view data of images recorded on the recording medium; Even grading to the thin thread part of literal, the concentration ground that the printed medium of the stain that is easy to spread and sink in is not reduced yet beat portion carries out sparse processing reliably; Eliminate the fuzzy of word segment, improve the repeatability of literal.In addition, the spread and sink in stain of China ink can be reduced, use chance can be increased the low paper of environment adverse effect to recording mediums such as low pulp content printing or mestha paper.

It should be noted that picture element density calculating part 114 has the kind of modifying according to the font size of the contained literal of view data and font, literal and waits the area that changes reference area A1 or the function of shape.Specifically; Area and shape as the acquiescence of reference area A1; Zone for the pixel count 5 * 5 of square shape; But picture element density calculating part 114 can extract the contained information relevant with view data in work data such as font size and the font of literal, the kind that literal is modified, and changes area or the shape of reference area A1.Also have, the information relevant with view data here can select signal to obtain from the contained processing literal font size of work data.
Change the area of reference area A1 or the function of shape through this, for example, the situation etc. that partly has No. 10 black face fonts that are easy to slightly blur at white pixel changes reference area A1 into 7 * 7, and obtains picture element density down.Like this, estimate the ratio of white pixel part lessly, make that the picture element density of this part is high, sparse rate is descended with beat portion with respect to reference area A1.
Above-mentioned sparse rate calculating part 115 is the picture element densities that calculate according to by picture element density calculating part 114, calculates the module for the sparse rate of gazing at pixel E1 of correspondence with reference to the table data D1 of storage part 103.These table data D1 is the data that the curve shown in available Fig. 4 (a) comes the corresponding relation of remarked pixel density and sparse rate in this embodiment, and the shape of available this curve freely sets the sparse rate for picture element density.
In this embodiment; The picture element density of table data D1 and the relation of sparse rate are set at: the sparse rate of the picture element density that predetermined threshold value (picture element density threshold value T1) is above is the specific higher limit (being 50% in the example of Fig. 4 (a)) less than 100%; And than picture element density threshold value T1 (in the example of Fig. 4 (a); 0.36=picture element density 36%) in the scope of high picture element density, set the feasible increase of sparse rate sparse rate reduced with picture element density.Particularly, the table data D1 here is that substantially to make sparse rate without exception at 0~36% o'clock be 50% at picture element density, for the zone higher than picture element density 36%, along with picture element density near 100%, and sparse rate is descended with near 0%.Like this, sparse rate is descended, and sparse rate is improved for the low blank parts of picture element density etc. for the high beat portion of picture element density etc.
The sparse rate conduct array data relevant of each pixel that this sparse rate calculating part 115 will calculate each pixel and importing to sparse handling part 116 with coordinate information.Sparse handling part 116 is modules that the basis pattern corresponding with sparse rate (pattern) makes the sparse processing that the concentration of each pixel reduces.The data of threshold matrix M1 that sparse handling part 116 uses in storage part 103 storages when sparse the processing.
Data of threshold matrix M1 is that to make 16 pixels of 4 * 4 shown in Fig. 4 (b) be unit cell pattern, and comes the wave filter to the threshold value of the sparse rate of whole pixel definitions through carrying out this operation repeatedly.At data of threshold matrix M1, threshold value that value is high and low threshold value are configured to Baeyer and arrange shape, so that not inclined to one side as the pixel of sparse objects.
Sparse handling part 116 is not repeatedly selected 4 * 4 16 pixels successively from the contained view data of work data.And, for each 16 pixel of 4 * 4, use data of threshold matrix M1 to carry out sparse processing.Particularly, each the sparse rate calculated by sparse rate calculating part 115 of selected 16 pixels and the threshold value that the respective pixel position defines respectively in data of threshold matrix M1 are compared.Comparative result, as shown in Figure 5, the sparse rate of each pixel is being higher than under the situation of threshold value, be that white pixel and sparse falls with this pixel replacement, be under the situation below the threshold value in sparse rate, do not carry out sparse to this pixel.Note, in Fig. 5, the sparse pixel of falling represented with white not have the sparse pixel of falling to use shadow representation.
Especially, in this embodiment, data of threshold matrix M1 constitutes, and the sparse pattern during the specific higher limit (50%) of table data D1 becomes alternate grid-like at a distance from a pixel whenever shown in Fig. 5 (a).That is, in each threshold value in the data of threshold matrix M1, the threshold value 50% or more is configured between mutual on x direction of principal axis and the y direction of principal axis across a pixel.Like this, even under sparse rate is maximum situation, it is sparse also can to make pixel not omit ground partially and not.
In addition, as stated, set sparse rate, so that the relation of the picture element density of table data D1 and sparse rate is for reduce sparse rate with the increase of picture element density pro rata in the scope of the picture element density higher than picture element density threshold value T1.Therefore, along with picture element density is more than the picture element density threshold value T1 (36%), sparse rate drops sharply to 20% (during picture element density 50%), then, along with picture element density reduces the situation of decline than 50% height gradually, drops to 0% from 20%.Accompany the formed sparse change in pattern of data of threshold matrix M1 with it.For example, be 35% o'clock in sparse rate, sparse pattern is changed to the pattern shown in Fig. 5 (b), is 25% o'clock in sparse rate, and sparse pattern is changed to the pattern shown in Fig. 5 (c).Have, drop at 10% o'clock in sparse rate, sparse pattern is changed to the pattern shown in Fig. 5 (d).And, along with picture element density makes sparse rate near 0% near 100%, be that sparse rate is 0% near 100% at picture element density, thereby do not carry out sparse.
