Here, specify the processing of in gray correction portion 21, carrying out according to Fig. 3 to Fig. 6.In addition, below, the example as mark exemplifies literal and describes.

At first, based on the classification information of the live width of the dimensional data of the character code of obtaining, literal, literal and the color data of literal, display control unit 16 is determined literal, character size, the live width classification of above-mentioned literal and the color of literal.Then, display control unit 16 is based on the character size of determining, the framework data of this literal of convergent-divergent.In addition, display control unit 16 is considered the classification of the live width of above-mentioned definite character size and literal, and decision is the live width (live width of appointment) during display text in the display frame of efferent 11.And then display control unit 16 utilizes the color (pixel value) of above-mentioned definite literal, and literal is presented in the display frame.In addition, with narrate in the back literal color utilize mode.

As its result, at first illustrate when in above-mentioned display frame, showing, determined to use the situation of live width of the odd number of pixels display text of continuous row by display control unit 16.Afterwards, illustrate when in above-mentioned display frame, showing, determined to use the situation of live width of the even number pixel display text of continuous row by display control unit 16.

In addition, below, use the odd number of pixels of continuous row to show under the situation of live width at signal conditioning package 1, this live width is called " odd number live width ".On the other hand, use the even number pixel of continuous row to show under the situation of live width, this live width is called " even number live width " at signal conditioning package 1.In addition, " odd number live width " and " even number live width " is meant and carries out the preceding live width of gray correction described later.If carry out gray correction, then a part of live width chap of literal.

At this, live width is described." live width " is meant the width of the literal of X-direction or Y direction.In addition, under the situation of the width that shows literal, use the pixel (pixel groups) of continuous row.For example, be under 3 the situation, to use 3 continuous pixels in live width.

In more detail, under the situation of the width of signal conditioning package 1 performance literal, use pixel that the key element line segment that comprises skeleton line overlaps and the pixel groups (key element pixel groups) of continuous row on X-direction or Y direction.Using which pixel groups in continuous one pixel groups that is listed as in the pixel groups of continuous row on the X-direction with on Y direction is to be determined by the slope of control part 15 according to above-mentioned key element line segment.

For example, under the absolute value of the slope of key element line segment was situation more than 1, signal conditioning package 1 used the pixel groups of continuous row on X-direction to show the width of literal.On the other hand, the absolute value of the slope of key element line segment less than 1 situation under, signal conditioning package 1 uses the width of the pixel groups performance literal of continuous row on Y direction.

Fig. 3 illustrates the figure that has proofreaied and correct the part of the literal after the literal of odd number live width by gray correction portion 21.In addition, Fig. 3 also is the figure of a part that the live width direction of literal is shown.

In Fig. 3, at first, because the absolute value of the slope of key element line segment L1 is more than 1, so live width is set in X-direction by control part 15.

In addition, in the structure in the past of not carrying out based on the correction of gray correction portion 21,3 pixels of the continuous row that pixel Pa, pixel Pb, the pixel Pc of odd number live width (in Fig. 3, live width is 3) amount is such become the pixel groups that constitutes literal.The center pixel that pixel Pb becomes pixel groups is because the central point C of pixel Pb is littler in the distance of X-direction than the central point and the key element line segment L1 of other pixels in the distance of X-direction with key element line segment L1.

In the present embodiment, signal conditioning package 1 also is that above-mentioned pixel Pa, pixel Pb and pixel Pc are used as the pixel groups that constitutes literal.

Distance calculation portion 20 calculates the central point C of pixel Pb and the key element line segment L1 distance in X-direction.That is, distance calculation portion 20 calculates the distance between the some G on central point C and the key element line segment L1 | d|.In other words, the central point and the distance of putting between the G in the pixel groups that is made of pixel Pa, pixel Pb and pixel Pc calculates in distance calculation portion 20.Here, calculating above-mentioned distance | during d|, the distance between the central point of pixel is made as 1.That is, | d| gets 0 to 0.5 value.In addition, some G also is by the point on the line of each central point in each pixel that forms a line on the live width direction of literal.

The pixel Pa that gray correction portion 21 will be positioned at the opposition side of a G with respect to central point C is defined as the calibration object pixel.In addition, gray correction portion 21 also will be defined as the calibration object pixel with pixel Pc adjacent pixels Pd on X-direction.Below, this (is for example proofreaied and correct preceding character area, pixel Pa, pixel Pb, pixel Pc) in the pixel value of literal be made as (R, G, B)=(Rf, Gf, Bf), the pixel value of proofreading and correct the background in the preceding background area (for example, pixel Pd) is made as (R, G, B)=(Rb, Gb, Bb) to be described.

Gray correction portion 21 uses following formula (1)～formula (3), and pixel Pa is carried out the correction of gray scale, and pixel value (R, G, B)=(Rm, Gm, the Bm) after obtaining to proofread and correct.Then, gray correction portion 21 is made as pixel value after the correction and the gray scale of proofreading and correct this pixel Pa with the pixel value of pixel Pa.

Rm＝(1-|d|)×Rf+|d|×Rb……(1)

Gm＝(1-|d|)×Gf+|d|×Gb……(2)

Bm＝(1-|d|)×Bf+|d|×Bb……(3)

In addition, gray correction portion 21 uses following formula (4)～formula (6), and pixel Pd is carried out the correction of gray scale, and pixel value (R, G, B)=(Rm, Gm, the Bm) after obtaining to proofread and correct.Then, gray correction portion 21 is made as pixel value after the correction and the gray scale of proofreading and correct this pixel Pd with the pixel value of pixel Pd.

Rm＝|d|×Rf+(1-|d|)×Rb……(4)

Gm＝|d|×Gf+(1-|d|)×Gb……(5)

Bm＝|d|×Bf+(1-|d|)×Bb……(6)

As mentioned above, pixel Pa and pixel Pd are corrected as: the gray scale between the background gray scale of the gray scale of literal and literal, and promptly with the corresponding gray scale of the distance that calculates by distance calculation portion 20.

In addition, carry out following correction by 21 couples of pixel Pa of gray correction portion, promptly along with distance | the value of d| becomes big, from the gray scale of the literal gray scale near background.On the other hand, carry out following correction by 21 couples of pixel Pd of gray correction portion, promptly along with distance | the value of d| becomes big, from the gray scale of the background gray scale near literal.

In addition, if the value addition of the R composition of the pixel Pd after the value of the R composition of the pixel Pa after will proofreading and correct and the correction then becomes Rf+Rb.That is, become with the pixel that will not become the calibration object pixel (pixel Pb or pixel Pc) in the value of R composition and the identical value of value after the value addition of the R composition in the pixel of above-mentioned background.In addition, also be identical about the value of G composition and the value of B composition.

As mentioned above, signal conditioning package 1 is proofreaied and correct live width from 3 be 4, and signal conditioning package 1 utilizes pixel Pa shown in Figure 3, pixel Pb, pixel Pc and pixel Pd to constitute the part of literal.

Fig. 4 similarly illustrates the figure that has proofreaied and correct the part of the literal after the literal of odd number live width by gray correction portion 21 with Fig. 3.The difference of Fig. 4 and Fig. 3 is that the some G of key element live width L1 is positioned at a side of more leaning on the negative direction of X-axis than the central point C of the pixel Pb that becomes center pixel.

Therefore, in Fig. 4, gray correction portion 21 is defined as the calibration object pixel with pixel Pc, and will be defined as the calibration object pixel with pixel Pa adjacent pixels Pe on X-direction.At this moment, 21 couples of pixel Pc of gray correction portion carry out the correction based on above-mentioned formula (1)～(3).On the other hand, 21 couples of pixel Pe of gray correction portion carry out the correction based on above-mentioned formula (4)～(6).

Fig. 5 illustrates the figure that has proofreaied and correct the part of the literal after the literal of even number live width by gray correction portion 21.In addition, Fig. 5 also is the figure of a part that the live width direction of literal is shown.

In Fig. 5, at first, because the absolute value of the slope of key element line segment L1 is more than 1, so control part 15 similarly is set in live width on the X-direction with Fig. 3 and Fig. 4.

In addition, in the structure in the past of not carrying out based on the correction of gray correction portion 21, two pixels of the continuous row that the pixel Pf of odd number live width (in Fig. 5, live width is 2) amount and pixel Pg are such become the pixel groups that constitutes literal.Here, why pixel Ph does not become the pixel that constitutes literal, is because the central point of pixel Pf is also littler in the distance of X-direction than central point and the key element line segment L1 of pixel Ph in the distance of X-direction with key element line segment L1 but pixel Pf becomes the pixel that constitutes literal.

In the present embodiment, signal conditioning package 1 also is used as the pixel groups that constitutes literal with above-mentioned pixel Pf and pixel Pg.

Distance calculation portion 20 calculates the central point C and the distance of key element line segment L1 on X-direction of the pixel groups that is made of pixel Pf and pixel Pg.That is, distance calculation portion 20 calculates the distance of the some G on central point C and the key element line segment L1 | d|.In other words, distance calculation portion 20 calculates the central point of boundary sections of pixel Pf and pixel Pg and the key element line segment L1 distance in X-direction.Here, calculating above-mentioned distance | during d|, also the distance between the central point of pixel is made as 1.That is, | d| gets 0 to 0.5 value.

Gray correction portion 21 uses above-mentioned formula (1)～formula (3), and pixel Pf is carried out the correction of gray scale, and pixel value (R, G, B)=(Rm, Gm, the Bm) after obtaining to proofread and correct.Then, gray correction portion 21 is made as pixel value after the correction and the gray scale of proofreading and correct this pixel Pf with the pixel value of pixel Pf.

In addition, gray correction portion 21 uses above-mentioned formula (4)～formula (6), and pixel Ph is carried out the correction of gray scale, and pixel value (R, G, B)=(Rm, Gm, the Bm) after obtaining to proofread and correct.Then, gray correction portion 21 is made as pixel value after the correction and the gray scale of proofreading and correct this pixel Ph with the pixel value of pixel Ph.

As mentioned above, pixel Pf and pixel Ph are corrected as following gray scale: the gray scale between the background gray scale of the gray scale of literal and literal, and promptly with the corresponding gray scale of the distance that calculates by distance calculation portion 20.

In addition, 21 couples of pixel Pf of gray correction portion carry out following correction, promptly along with distance | and the value of d| becomes big, from the gray scale of the literal gray scale near background.On the other hand, 21 couples of pixel Ph of gray correction portion carry out following correction, promptly along with distance | and the value of d| becomes big, from the gray scale of the background gray scale near literal.

In addition, if the value addition of the R composition of the pixel Ph after the value of the R composition of the pixel Pf after will proofreading and correct and the correction then becomes Rf+Rb.That is, become with the pixel (pixel Pg) that will not become the calibration object pixel in the value of R composition and the identical value of value after the value addition of the R composition in the pixel of above-mentioned background.In addition, also be identical for the value of G composition and the value of B composition.

As mentioned above, signal conditioning package 1 is proofreaied and correct live width from 2 be 3, and signal conditioning package 1 constitutes the part of literal by pixel Pf shown in Figure 5 and pixel Ph.

Fig. 6 similarly illustrates the figure that has proofreaied and correct the part of the literal after the literal of even number live width by gray correction portion 21 with Fig. 5.The difference of Fig. 6 and Fig. 5 is that the some G of key element live width L1 is positioned at a side (left side of Fig. 6) of more leaning on the negative direction of X-axis than the central point C of the pixel groups that is made of pixel Pf and pixel Pg.

Therefore, in Fig. 6, gray correction portion 21 is defined as the calibration object pixel with pixel Pg, and will be defined as the calibration object pixel with pixel Pf adjacent pixels Pi on X-direction.At this moment, 21 couples of pixel Pg of gray correction portion carry out the correction based on above-mentioned formula (1)～(3).On the other hand, 21 couples of pixel Pi of gray correction portion carry out the correction based on above-mentioned formula (4)～(6).

In addition, because above-mentioned some G becomes computed range | the object of the processing of d|, so the following G that will put is called " process object point G ".

Fig. 7 is the process flow diagram that the flow process of the processing in the signal conditioning package 1 is shown.Especially, Fig. 5 shows signal conditioning package 1 literal is presented at situation in the display frame.

At first, display control unit 16 is obtained the character code about the literal that becomes display object, the size of literal, the classification information of word line width and the such Word message (S1) of color of literal.The literal that becomes display object both can be the literal via input part 10 inputs, perhaps also can be the literal that is stored in advance in the signal conditioning package 1.By this step S1, determine the classification of live width of literal, character size, literal and the color of literal.

After step S1, display control unit 16 is read according to the determined framework data of the above-mentioned character code of obtaining (S2) from memory storage 12.In addition, the framework data of reading temporarily are stored in the first memory 13.Then, after step S2, display control unit 16 carries out convergent-divergent (S3) based on above-mentioned definite character size to the framework data of reading.

After step S3, obtain the stroke information (S4) relevant the framework data of display control unit 16 after convergent-divergent with the skeleton line of a stroke.In addition, stroke information is with identical in the stroke information shown in the patent documentation 1.In the example of Chinese character " wood ", there are 4 stroke information about this Chinese character.

After step S4, display control unit 16 is based on the classification information of the live width of stroke information that obtains and above-mentioned definite literal, the describing of the stroke of the live width of stipulating (live width of appointment) (S5).Then, after step S5, display control unit 16 judges whether the whole strokes that are included in this literal have been carried out above-mentioned describing (S6).Here, above-mentioned " live width of regulation " is meant the live width of having carried out the literal after the correction by gray correction portion 21.

Be judged to be in S6 and whole strokes do not carried out under the above-mentioned situation about describing, signal conditioning package 1 returns processing step S4 once more.On the other hand, in S6, be judged to be whole strokes have been carried out under the above-mentioned situation about describing, a series of processing that signal conditioning package 1 finishes for this literal.

Fig. 8 is the process flow diagram of details of processing that the step S5 of Fig. 7 is shown.In addition, in Fig. 8, the absolute value that exemplifies the slope of key element line segment is the situation more than 1, and about each key element line segment, is that example describes with the Y coordinate situation littler than the Y coordinate of the terminal point of this key element line segment of the starting point of key element line segment.

In addition, below illustrate following formation: computational element line segment and above-mentioned central point C X-direction apart from the time, formerly obtain on the basis of the process object point G on the key element line segment, calculate the distance of this process object point G and central point C.

At first, distance calculation portion 20 is based on stroke information, obtains the coordinate figure (S11) of two points of two ends (starting point and terminal point) of a key element line segment.After step S11, the slope k (S12) of above-mentioned key element line segment is calculated based on the above-mentioned coordinate figure of obtaining by distance calculation portion 20.Here, with the line of live width direction (X-direction in Fig. 3 to Fig. 6), promptly the line through the center of each pixel is called " dummy line L2 ".

After step S12, distance calculation portion 20 is based on the starting point coordinate and the terminal point coordinate of this key element line segment, obtains near intersection point (S13) two ends of key element line segment, this key element line segment and above-mentioned dummy line L2.At this moment, in the pixel that the end of key element line segment overlaps, under the situation of not intersecting with the dummy line L2 at center by this pixel, the extended line and the point that this dummy line L2 intersects of this key element line segment is made as above-mentioned intersection point because the key element line segment is short.In addition, below, the intersection point of starting point side is made as " some S ", the intersection point of terminal point side is made as " some E ".

After step S13, distance calculation portion 20 is set at a S (S14) with above-mentioned process object point G.Then, after step S14, distance calculation portion 20 judges whether the live width of above-mentioned decision is odd number (S15).

Be judged as in step S15 under the situation of odd number, distance calculation portion 20 obtains the central point C (S16) of the pixel of the most approaching above-mentioned process object point G.After step S16, the distance of the 20 computing object-point G of distance calculation portion and the central point C that obtained | d| (S17).Specifically, the X that process object is put G of distance calculation portion 20 absolute value of sitting target value and the difference of the X seat target value of above-mentioned central point C is made as distance | d|.

After step S17, gray correction portion 21 with the pixel that will have above-mentioned central point C as the live width amount of the X-direction at center (that is, the live width amount before proofreading and correct) pixel groups is a benchmark, carries out corresponding to above-mentioned distance | the correction of the gray scale of d| (S18).With this pixel groups is benchmark, gray correction portion 21 carries out above-mentioned correction, thereby or as shown in Figure 4 as Fig. 3, to the pixel of an end of this pixel groups (for example, the pixel Pa of Fig. 3), carry out the correction of gray scale with the pixel adjacent pixels (for example, the pixel Pd of Fig. 3) of another end of this pixel groups.Then, after step S18, signal conditioning package 1 is advanced to step S19 with processing.

In step S15, be judged as under the situation that is not odd number the boundary sections (S20) between the pixel of the 20 the most approaching definite above-mentioned process object point G of distance calculation portion.After step S20, the distance of 20 computing object-point G of distance calculation portion and the boundary sections of determining | d| (S21).That is the distance of the 20 computing object-point G of distance calculation portion and the central point apart from line segment (being central point C) determined.Specifically, the X that process object is put G of distance calculation portion 20 X that sits target value and the boundary sections absolute value of sitting the difference of target value is made as distance | d|.

After step S21, gray correction portion 21 carries out corresponding to above-mentioned distance to be benchmark with above-mentioned central point C as the pixel groups of the live width amount of the X-direction at the center of pixel groups | the correction of the gray scale of d| (S22).With this pixel groups is benchmark, gray correction portion 21 carries out above-mentioned correction, thereby or as shown in Figure 6 as Fig. 5, to the pixel of an end of this pixel groups (for example, the pixel Pf of Fig. 5), carry out the correction of gray scale with the pixel adjacent pixels (for example, the pixel Ph of Fig. 5) of another end of this pixel groups.Then, after step S22, signal conditioning package 1 is advanced to step S19 with processing.

In step S19, distance calculation portion 20 sits the above-mentioned value k of addition on the target value at the X of process object point G, sits addition 1 on the target value at Y.After step S19, whether the coordinate figure of control part 15 judgment processing object-point G consistent with the coordinate figure of above-mentioned some E (S23).

Be judged as in step S20 under the inconsistent situation, signal conditioning package 1 is back to processing step S15 once more.On the other hand, be judged as in step S20 under the consistent situation, display control unit 16 judges whether the whole key element line segments in the skeleton line that is included in stroke have been carried out the processing (S24) to step S23 based on above-mentioned step S12.

Be not judged as in step S24 whole line segment key elements have been carried out under the situation of processing, signal conditioning package 1 is back to processing step S11 once more.On the other hand, be judged as in step S24 under the situation that whole line segment key elements have been carried out handling, signal conditioning package 1 is back to processing the step S6 of Fig. 7.

Fig. 9 is the figure that is used to illustrate the effect of above-mentioned gray correction.Fig. 9 (a) is the figure that the literal (part) when not carrying out above-mentioned gray correction is shown, and Fig. 9 (b) is the figure that the literal (part) when having carried out gray correction is shown.

Shown in Fig. 9 (a), do not carrying out under the situation of above-mentioned gray correction, sawtooth is clearly.But shown in Fig. 9 (b), by carrying out above-mentioned gray correction, sawtooth becomes not obvious as can be known, and profile becomes slick and sly.

As mentioned above because signal conditioning package 1 carries out corresponding to distance | the correction of the gray scale of d|, thus signal conditioning package 1 need be at timing with the data storage that is used for gray correction of look-up table etc. at memory storage.In addition, because signal conditioning package 1 is only according to distance | d| comes the gray scale of calculating pixel, so compare with the structure of visiting the data in look-up table by each pixel, signal conditioning package 1 can shorten the required time of gray correction.

In addition, in the data storage areas of the second memory 14 that plays the VRAM effect, under video data generating unit 22 situation of literal of gray scale that generated such as mentioned above correction, following two kinds of methods are arranged.

First method is directly to describe the method for the data of literal in second memory 14.That is, will be stored in data (that is, the video data in the demonstration) in the second memory 14, and signal conditioning package 1 carries out the method (below, be called direct plotting method) of the correction of gray scale as the background data of literal.

Second method is, with text color contribution degree described later be stored in storer beyond the second memory 14 (below, be called temporary storage) in, and signal conditioning package 1 use this literal color contributions degree update stored in the data (video data in the demonstration) in the second memory 14 method (below, be called indirect plotting method.

Below, direct plotting method at first is described, indirect plotting method is described afterwards.

Figure 10 is the process flow diagram that the flow process of the processing when carrying out direct plotting method is shown.Specifically, show the step S18 in the flow process of Fig. 8 and the process flow diagram of the processing among the step S22.

Here, for convenience of explanation, use this notion of text color contribution degree." text color contribution degree " is meant that the color (being the value of each color component in detail) that gray correction portion 21 is carried out the literal before the gray correction is made as 100, is that what value the color of the literal before the gray correction literal after to gray correction contributed.

Specifically, its text color contribution degree of the pixel Pa of Fig. 3 becomes 100 * (1-|d|).In addition, because pixel Pb and the pixel Pc of Fig. 3 do not carried out gray correction, so the text color contribution degree becomes 100.And its text color contribution degree of the pixel Pd of Fig. 3 becomes 100 * | d|.In addition, in the zone beyond pixel Pa～Pd of Fig. 3, the text color contribution degree becomes 0.

At first, display control unit 16 is determined the upgating object pixel in the second memories 14, and obtains the text color contribution degree (S31) corresponding to this pixel.After step S31, display control unit 16 judges whether the text color contribution degree is 100 (S32).

Be judged as contribution degree be in step S32 under 100 the situation, gray correction portion 21 utilizes pixel value (Rf, Gf, Bf) to upgrade the pixel value (S33) of above-mentioned upgating object pixel.That is, gray correction portion 21 utilizes text color itself that the upgating object pixel is upgraded.

On the other hand, do not judge contribution degree be in step S32 under 100 the situation, the pixel value (Rb, Gb, Bb) that gray correction portion 21 obtains above-mentioned upgating object pixel (S34).After step S34, the text color contribution degree that gray correction portion 21 uses pixel values (Rf, Gf, Bf), pixel value (Rb, Gb, Bb) and obtains calculates the pixel value (S35) after the correction.In addition, because above-mentioned formula (1)～(3) and formula (4)～(6) are used in the calculating of the pixel value after proofreading and correct, so omit its explanation here.In addition, in formula (1)～(6), use with the text color contribution degree divided by 100 value (that is, 1-|d| or | d|) calculate.

After step S35, gray correction portion 21 utilizes the pixel value after proofreading and correct to upgrade the pixel value (S36) of above-mentioned upgating object pixel.Thus, the gray scale of the pixel Pa of Fig. 3 and pixel Pd is corrected.

Figure 11 shows the process flow diagram of a part of the flow process of the processing when carrying out indirect plotting method.

At first, the upgating object pixel that display control unit 16 is determined in the above-mentioned temporary storage, and obtain and the corresponding text color contribution degree of this pixel K1 (S41).After step S41, display control unit 16 judges whether the text color contribution degree of above-mentioned upgating object pixel has been stored in the above-mentioned temporary storage (S42).

Be judged as in step S42 under the situation that stores the text color contribution degree, control part 15 judges that whether the text color contribution degree K1 that obtains is greater than the text color contribution degree K2 (S43) that has stored in step S41.On the other hand, do not judge in S42 under the situation that has stored the text color contribution degree, signal conditioning package 1 is advanced to step S44 with processing.

Be not judged as in step S43 under the big situation, signal conditioning package 1 is advanced to step S45 with processing.On the other hand, be judged as in step S43 under the big situation, signal conditioning package 1 is advanced to step S44 with processing.In step S44, the text color contribution degree of upgating object pixel is set at K1.Then, after step S44, signal conditioning package 1 is advanced to step S45 with processing.

In step S45, display control unit 16 judges whether to handle being included in a update all object pixel in the literal.Be not judged as in step S45 the update all object pixel has been carried out under the situation of processing, signal conditioning package 1 is back to S41 with processing once more.

On the other hand, in step S45, be judged as under the situation that the update all object pixel has been carried out handling, signal conditioning package 1 uses the text color contribution degree of storing in the temporary storage to calculate the pixel value of each pixel, and uses this pixel value that calculates to upgrade pixel value (S46) in the second memory 14.Upgrade processing by this, carry out the correction of gray scale.In addition, because signal conditioning package 1 uses above-mentioned formula (1)～(3) and formula (4)～(6) to calculate pixel value, so no longer repeat specification here.

Because plotting method is a structure of upgrading the pixel value in the second memory 14 on the basis of the text color contribution degree of obtaining the update all object pixel indirectly, so be different from the flow process of the Fig. 7 that describes by each stroke.

In addition, use above-mentioned direct plotting method by signal conditioning package 1, signal conditioning package 1 does not need to be used for the temporary storage of indirect plotting method.In addition, owing to do not need 14 pass on, so signal conditioning package 1 can be realized the high speed handled from temporary storage to second memory yet.

On the other hand, use indirect plotting method by signal conditioning package 1, even at the position that the key element line segment intersects, the position that the key element line segment is intensive, signal conditioning package 1 also can prevent the situation that the gray scale of text color becomes higher than the gray scale at other positions.

In addition, in above-mentioned, if the key element line segment is parallel with X-axis or parallel with Y-axis, then signal conditioning package 1 carries out the correction of above-mentioned gray scale by gray correction portion 21.But mark of being described by the key element line segment that is parallel to X-axis (part of mark) and the mark of being described by the key element line segment that is parallel to Y-axis (part of mark) just can not produce stair-stepping burr (sawtooth) originally.Therefore, preference information treating apparatus 1 only carries out the correction of above-mentioned gray scale at the key element line segment (that is the line segment of inclination) that has slope with respect to X-axis and Y-axis.

Therefore, below, descriptive information treating apparatus 1 utilizes the structure of parallel detection unit 30 and correction limit portion 31.

Parallel detection unit 30 judges based on scaled framework data (information of expression skeleton line) whether each key element line segment is the straight line parallel with X-axis or Y-axis.

Correction limit portion 31 is for comprising that the key element pixel groups with the pixel that is judged to be parallel key element line segment coincidence by parallel detection unit 30 limits correction according to the mode of not carrying out the correction of above-mentioned gray scale.

Figure 12 is the figure that the part of the mark that is obtained under the situation of the restriction that utilizes parallel detection unit 30 and correction limit portion 31 to carry out correction is shown.In addition, in Figure 12, dotted line is the line that has connected between the central point of pixel.

As shown in figure 12, key element line segment L3 is the line segment of oblique line, and key element line segment L4 is the line segment that is parallel to Y-axis.Under the situation of signal conditioning package 1 based on the part of key element line segment L3 display text, as shown in figure 12, gray correction portion 21 carries out the correction of gray scale.And by this correction, line segment is increased to 4 from 3.On the other hand, under the situation of signal conditioning package 1, as shown in figure 12, proofread and correct the correction of display part 31 restriction gray scales based on the part of key element line segment L4 display mark.

Its result, signal conditioning package 1 can make the sawtooth of the word segment of inclination become not obvious, and for the word segment that is parallel to Y-axis, the situation that can avoid literal to thicken.And then, owing to do not need the key element line segment that is parallel to X-axis or Y-axis is carried out based on distance | the computing of the gray correction of d|, so compare with the structure of this parallel key element line segment being carried out the computing of gray correction, signal conditioning package 1 can shorten the required time of demonstration.

Like this, it is following structure that correction limit portion 30 can be called: at comprise with the key element pixel groups that is judged to be the pixel that parallel key element line segment overlaps by parallel detection unit 30 in the pixel of an end (in Figure 12, pixel Pj for example), promptly not being included in pixel in this key element pixel groups (in Figure 12, for example pixel Pk) restriction gray correction portion 21 with above-mentioned another end adjacent pixels of this key element pixel groups proofreaies and correct.

In addition, use correction limit portion 31 to carry out producing following problem under the situation of correction of gray scale as described above at signal conditioning package 1.

Figure 13 is the figure of the part of the key element line segment L5 that illustrates to utilize and the literal depicted in the key element line segment L6 of this key element line segment L5 continuously.In addition, in Figure 13, carry out the restriction of above-mentioned correction by correction limit portion 31.

At this moment, as shown in figure 13,1 couple of pixel Pm of signal conditioning package and pixel Pn carry out the correction of gray scale.Therefore, in the zone of the reflex angle side in the angle that forms by key element line segment L5 and key element line segment L6 (angle is the above sides of 180 degree), can be to the outline line formation protuberance of the mark that is parallel to Y-axis.Therefore, literal seems poor effect.

Therefore, below, illustrate that the part of the function of change correction limit portion 31 makes signal conditioning package 1 prevent that literal from seeming the structure of the situation of weak effect.

Figure 14 illustrates the function of such change correction limit portion 31 and the figure of the part of the literal that obtains.Utilize above-mentioned key element line segment L5 and above-mentioned key element line segment L6 to describe under the situation of a part of literal at signal conditioning package 1, as shown in figure 15, signal conditioning package 1 does not carry out the correction of gray scale to pixel Pm and pixel Pn at least.

Below, be used to show such processing that seems effective literal based on Figure 15 to Figure 18 explanation.

Figure 15 is the figure that is illustrated in employed each key element line segment when describing some strokes.In Figure 15, record three key element line segment L10, L11, L12.In addition, in Figure 15, the starting point of key element line segment L10 is made as a H, the terminal point of key element line segment L10 and the starting point of key element line segment L11 are made as an I, the terminal point of key element line segment L11 and the terminal point of key element line segment L12 are made as a J, the terminal point of key element line segment L12 is made as a K.

In addition, suppose in scaled coordinate data that the coordinate figure of the coordinate figure of the coordinate figure of some H, some I, the coordinate figure of some J, some K is tactic according to this.And then, be made as signal conditioning package 1 and describe stroke at first based on key element line segment L10, afterwards, carry out based on the describing of the stroke of key element line segment L11, carry out describing at last based on the stroke of key element line segment L12.

And then, when signal conditioning package 1 carries out based on the describing of the stroke of key element line segment L11, key element line segment L10 is called " rendered object immediately following preceding key element line segment ", key element line segment L12 is called " the back to back key element line segment of rendered object ".In addition, in Figure 15, be above-mentioned process object point G at the point that is used on this key element line segment L11 that describes, the point handled is at first shown as an E as a S, the point that will handle at last.And then, the slope of key element line segment L11 is made as more than 1.

Below, under such definition, the particular content of handling is described.

Figure 16 is illustrated in the process flow diagram that stroke is described the details of the processing in (the step S5 of Fig. 7).

At first, obtain the framework data of display control unit 16 behind convergent-divergent key element line segment L10 coordinate figure (that is, the some H among Figure 15 and the some I coordinate figure) (S51).After step S51, distance calculation portion 20 calculates the slope (S52) of key element line segment L10.Then, after step S52, distance calculation portion 20 calculates above-mentioned some S and the coordinate figure (S53) of putting E.And then after step S53, distance calculation portion 20 puts G with process object and is set at a S (S54).

After step S54, display control unit 16 is set the higher limit Xmax and the lower limit Xmin (S55) of X-direction.Here, display control unit 16 is set the higher limit of X-direction and the reason of lower limit is because the slope of key element line segment L10 is more than 1, and forms live width in X-direction.In addition, be that slope is under the situation below 1 at the key element line segment, capping value and lower limit on Y direction.Then, after step S55, distance calculation portion 20 judges whether live width is odd number (S56).In addition, the live width here is to carry out gray correction live width before.

Being judged as in step S56 is under the situation of odd number, and distance calculation portion 20 obtains the X coordinate figure (S57) near the central point (that is central point C) of the pixel of process object point G.In addition, below, the coordinate figure of process object being put G is labeled as (Xg, Yg), the coordinate figure of central point C is labeled as (Xc, Yc).In addition, at this moment, Yg becomes identical value with Yc.That is, the coordinate figure of central point C is also represented as (Xc, Yg).

After step S57, distance calculation portion 20 judges whether Xg is the above and Xmax following (S58) of Xmin.Judge in step S58 is that distance calculation portion 20 calculates the distance of process object point G and central point C under the situation more than the Xmin and below the Xmax | d| (S59).Then, after step S39, the distance that gray correction portion 21 utilizes distance calculation portion 20 to calculate | d|, a part (with reference to Fig. 3) of describing stroke as mentioned above like that is (S60).Then, after step S60, distance calculation portion 20 adds above-mentioned k on the X of process object point G coordinate figure, and adds 1 (S61) on the Y coordinate figure of this process object point G.

On the other hand, do not judge in step S58 is under the situation more than the Xmin and below the Xmax, distance calculation portion 20 is made as the central point of the pixel groups (key element pixel groups) that is made of pixel continuous on the online cross direction with point (Xc, Yg), and display control unit 16 does not carry out gray correction as in the past but describes the part (S62) of stroke.That is, pixel Pn shown in Figure 14 and pixel Pm are not carried out the correction of gray scale, signal conditioning package 1 can make this pixel Pn, Pm keep original background color.Therefore, signal conditioning package 1 can obtain the literal that seems effective.After step S62, signal conditioning package 1 is advanced to step S61 with processing.

In addition, not judging in step S56 is under the situation of odd number, and distance calculation portion 20 obtains the coordinate figure (S63) near the central point (that is central point C) of the above-mentioned boundary sections of process object point G.

After step S63, distance calculation portion 20 judges whether Xg is the above and Xmax following (S64) of Xmin.Judge in step S64 is that distance calculation portion 20 calculates the distance of process object point G and central point C under the situation more than the Xmin and below the Xmax | d| (S65).Then, after step S59, the distance that gray correction portion 21 utilizes distance calculation portion 20 to calculate | d|, a part (with reference to Fig. 5) of describing stroke as mentioned above like that is (S66).Then, after step S66, signal conditioning package 1 is advanced to step S61 with processing.

On the other hand, not judging in step S64 is that signal conditioning package 1 is advanced to step S62 with processing under the situation more than the Xmin and below the Xmax.

After step S61, the coordinate figure of the 20 judgment processing object-point G of distance calculation portion whether with the coordinate figure identical (S67) of an E.Do not judge in step S67 under the identical situation, signal conditioning package 1 is back to processing step S56 once more.On the other hand, judge in step S67 under the identical situation, display control unit 16 judges whether the whole key element line segment L10, L11, the L12 that are comprised in the above-mentioned stroke have been carried out handling (S68).

Do not judge in step S68 under the situation that whole key element line segments have been carried out handling, signal conditioning package 1 is back to processing step S51 once more.On the other hand, in step S68, judge whole key element line segments have been carried out under the situation of processing, signal conditioning package 1 end process.

Figure 17 is the process flow diagram that the establishing method of higher limit among the step S55 of Figure 16 and lower limit is shown.In addition, describe for ease of illustrating, exemplifying for the higher limit of key element line segment L11 and the setting of lower limit.

At first, display control unit 16 is based on the coordinate figure of a H and some I, judge immediately following preceding key element line segment L10 whether be parallel to X-axis or Y-axis line segment (horizontal line or ordinate) (S71).Judge in step S71 is that display control unit 16 judges whether live width is odd number (S72) under the situation of parallel line segment.In addition, the live width here is to carry out gray correction live width before.

Judging in step S72 is under the situation of odd number, and display control unit 16 is set at lower limit Xmin the X coordinate figure (S73) of coordinate of the central point of the pixel that comprises a S.Afterwards, signal conditioning package 1 is advanced to step S76 with processing.On the other hand, not judging in step S72 is under the situation of odd number, and display control unit 16 is set at lower limit Xmin the X coordinate figure (S74) of the above-mentioned boundary sections of closest approach S.Afterwards, signal conditioning package 1 is advanced to step S56 with processing.

In addition, not judging in step S51 is that display control unit 16 is set at lower limit Xmin the value (S75) of the minimum in the desirable value of Xg under the situation of parallel line segment.Afterwards, signal conditioning package 1 is advanced to step S76 with processing.

In step S76, display control unit 16 judges based on the coordinate figure of a J with some K whether back to back key element line segment L12 is the line segment that is parallel to X-axis or Y-axis.Judge in step S76 is that display control unit 16 judges whether live width is odd number (S77) under the situation of parallel line segment.In addition, the live width here is to carry out gray correction live width before.

Judging in step S77 is under the situation of odd number, and display control unit 16 is set at higher limit Xmax the X coordinate figure (S78) of coordinate of the central point of the pixel that comprises an E.Afterwards, signal conditioning package 1 end process.On the other hand, not judging in step S77 is under the situation of odd number, and display control unit 16 is set at higher limit Xmax the X coordinate figure (S79) of the above-mentioned boundary sections of closest approach E.Afterwards, signal conditioning package 1 end process.

In addition, not judging in step S77 is that display control unit 16 is set at higher limit Xmax the value (S80) of the maximum in the desirable value of Xg under the situation of parallel line segment.Afterwards, signal conditioning package 1 end process.

Figure 18 (a) is the figure that illustrates shown in the process flow diagram of Figure 17 like that about the higher limit Xmax of X coordinate, and Figure 18 (b) is the figure that illustrates shown in the process flow diagram of Figure 17 like that about the lower limit Xmin of X coordinate.In addition, Figure 18 (c) is the figure that illustrates about the higher limit Ymax of Y coordinate, and Figure 18 (b) is the figure that illustrates about the lower limit Ymin of Y coordinate.

Here, will be made as " dummy line L15 (first dummy line) " through the line of each central point in each key element pixel groups that comprises the pixel that overlaps with the key element line segment (for example, the ordinate of Figure 18 or horizontal line) that is parallel to X-axis or Y-axis.That is, if the key element line segment is parallel to X-axis, then dummy line L15 becomes the line segment that is parallel to X-axis, if the key element line segment is parallel to Y-axis, then dummy line L15 becomes the line segment that is parallel to Y-axis.In addition, the thick dotted line of Figure 13 and Figure 14 is equivalent to dummy line L15.

As mentioned above, if defining virtual line L15 and dummy line L16, then dummy line L16 with above-mentioned other the position of intersection point of key element line segment and the position of dummy line L15 satisfy under the situation of the relation of stipulating, correction limit portion 31 can be described as following structure.Promptly, can be described as following structure: proofread and correct the pixel of an end in the key element pixel groups that display part 31 included at the pixel that will overlap with this intersection point, on described live width direction with this key element pixel groups in the pixel adjacent pixels of described another end promptly be not included in pixel in this key element pixel groups, limit and carry out the correction of gray scale by gray correction portion 21.

In addition, in Figure 14 to Figure 18, in order to show the literal that seems effective, the pixel of 31 pairs of regulations of correction limit portion (for example, the pixel Pm of Figure 14 and pixel Pn) has limited the correction of gray scale.Below, for being shown, signal conditioning package 1 seems effective literal equally, descriptive information treating apparatus 1 uses the structure of line segment correction unit 32.

The key element line segment of 32 pairs of regulations of line segment correction unit does not change the slope of key element line segment, but changes the length of key element line segment.In detail, line segment correction unit 32 is by the coordinate figure of the starting point of each key element line segment of change and the coordinate figure of terminal point, thus the length of change key element line segment.

Figure 19 illustrates by line segment correction unit 32 to proofread and correct preceding key element line segment L20, L21 and the key element line segment L20 ' after the correction, the figure of L21 '.Figure 19 (a) illustrates the key element line segment before proofreading and correct, and Figure 19 (b) illustrates the key element line segment after the correction.
