Above-mentioned CRT6 has in the horizontal direction each pixel that is rectangular configuration on each point of crossing of many data signal lines of the multi-strip scanning line of (first direction) and vertical direction (second direction) respectively, can utilize above-mentioned each pixel color Displaying graphical objects.In addition, above-mentioned CRT6 can certainly be flat-panel monitors such as LCD panel, plasma display panel.
Here, preserve the data that realize program that the present invention uses and this program, be the various control informations of gray scale at HD8 etc.Before the present invention carried out, CPU1 utilized HDC7, from HD8 by system bus 4, with the program primary memory 2 of packing into.When the present invention carried out, CPU1 carried out the program on the primary memory 2, and the primary memory space on graphic memory 3 is described.CRTC5 is presented at the graph data of describing in the graphic memory 3 on the CRT6 by system bus 4.In addition, HDC7 and HD8 can not be hard disks also, so long as external memory is all right.
Such image processing apparatus is further represented from function, it has at the greyscale pattern generating apparatus of primary memory 2 generations along the basic greyscale pattern of some directions of above-mentioned horizontal direction and vertical direction, come according to the distance that on the direction vertical, is offset with the direction of above-mentioned basic greyscale pattern, decision along the direction of above-mentioned basic greyscale pattern describe the starting position describe the determining positions device, describe the greyscale pattern drawing apparatus that the storage space of starting position on graphic memory 3 described above-mentioned basic greyscale pattern from above-mentioned, and control above-mentioned determining positions device and the greyscale pattern drawing apparatus described, make its one side repeat the CPU (control device) 1 of above-mentioned basic greyscale pattern along the direction skew one side vertical with the direction of above-mentioned basic greyscale pattern.
The greyscale pattern generating apparatus is made of primary memory 2 and CPU1, and CPU1 carries out program stored in the above-mentioned primary memory 2, generates the basic greyscale pattern of any direction in horizontal direction or the vertical direction.
Describe the determining positions device and be made of primary memory 2 and CPU1, CPU1 carries out program stored in the above-mentioned primary memory 2.Details will be narrated in the back, it is to carry out said procedure by CPU1, according to the information at the reference mark (color base on schedule) of starting point in the gray scale vector, that determine accordingly with length and end point (below be designated as vector starting point and vector end point) and polychrome gray scale etc., calculate " side-play amount " of each layer as the horizontal direction of the Drawing Object of object or vertical direction.The change direction of the color that above-mentioned so-called gray scale vector is a gray scale, concentration etc.In addition, above-mentioned so-called layer is meant for example aggregate of each pixel of delegation or at least one row and the view data corresponding with them at least along the direction of above-mentioned basic greyscale pattern.
The greyscale pattern drawing apparatus is made of primary memory 2 and CPU1, CPU1 carries out program stored in the above-mentioned primary memory 2, with the basic greyscale pattern that the greyscale pattern generating apparatus generates,, utilize CRTC5 to be shown on the CRT6 according to describing " side-play amount " that the determining positions device calculates.
Owing to adopt such formation can realize the present invention, therefore with realizing the present invention simply on the devices such as personal computer and mobile device, portable terminal or PDIA.
The image processing method of the present invention of above-mentioned formation is adopted in explanation with reference to the accompanying drawings.
The greyscale pattern that above-mentioned image processing method comprises the basic greyscale pattern that generates along continuous straight runs or vertical direction generates step, according to the distance that on the direction vertical, is offset with the direction of above-mentioned basic greyscale pattern, determine above-mentioned basic greyscale pattern describe the starting position describe the determining positions step and from the above-mentioned starting position of describing, the greyscale pattern of describing above-mentioned basic greyscale pattern is described (copy) step, be one side along the skew of above-mentioned vertical direction, one side repeats the above-mentioned method that determining positions step and greyscale pattern are described step of describing.
Just, in coordinate system for example shown in Figure 1, from vector starting point (starting point the figure) S (sx, sy) (ex is on direction ey), in order to form gray scale to vector end point (end point among the figure) E, the basic greyscale pattern that forms approx with forming that multilayer is parallel to directions X or Y direction, make adjacent layer basic greyscale pattern describe offset, describe, form gray scale.At this moment, " side-play amount " k of the basic greyscale pattern of the basic greyscale pattern of n layer with respect to the 1st layer is as described below calculating.
When the layer of basic greyscale pattern was illustrated in figure 1 as laterally (directions X), " side-play amount " k of n layer was k=| (ey-sy)/(ex-sx) * n|.In contrast, when the layer of basic greyscale pattern be vertical (Y direction), " side-play amount " k of n layer can (ex-sx)/(ey-sy) * n| calculates according to k=|.In addition, in following each figure, basic greyscale pattern only is designated as greyscale pattern.
Aforementioned calculation is to be that unit carries out with the layer, therefore be that unit obtains gray color and compares with the point, can adopt simple calculating.In addition owing to can be that unit handles with the layer, therefore be that the situation that unit handles is compared with the pixel, can cut down calculated amount.Also have, when " side-play amount " k is somebody's turn to do in calculating, handle, can not use floating point, only carry out integer arithmetic by result of calculation being carried out rounding-off method.
Generate in the step in above-mentioned greyscale pattern, preferably the size of the basic greyscale pattern of Sheng Chenging is greater than the size of Drawing Object.The size of above-mentioned so-called Drawing Object hypothesis is meant the size with the Drawing Object of basic greyscale pattern parallel direction.
That is to say, preferably form basic greyscale pattern like this, make in the basic greyscale pattern of ground floor, for and the vector starting point of gray scale vector and vector end point between the pixel of position in addition, corresponding position (following note is made the correspondence position with the gray scale vector) can describe.Here, the correspondence position of so-called and gray scale vector is meant with the gray scale resolution of vectors during for each component, and is parallel to the suitable position, position component, between the Origin And Destination of the direction of basic greyscale pattern.Below pixel suitable with this starting point and terminal point in the basic greyscale pattern remembered respectively make starting point and end point.
That is to say,, be predetermined and handle being in describing that pixel beyond the correspondence position with the gray scale vector carries out at the generation phase of basic greyscale pattern.By like this, from the offset of describing of ground floor, when describing the second layer and later basic greyscale pattern, the pixel that Drawing Object comprised also can all utilize basic greyscale pattern to describe.In other words, even be offset the position of describing of basic greyscale pattern, in Drawing Object, there is not the pixel of utilizing basic greyscale pattern to fail to describe yet.
Thereby, for the pixel that is comprised in the Drawing Object, owing to need therefore not cutting down calculated amount in order to be that unit differentiates the starting point whether be in basic gray scale and the processing between the end point and each pixel of Drawing Object is described to calculate with the pixel.
For example, shown in Fig. 3 (a)～Fig. 3 (c), generation phase in basic greyscale pattern, if beyond between the starting point of this basic greyscale pattern and the end point, starting point one side is all described with the color of starting point, and end point one side is all described with the color of end point, then can realize the effect (with reference to Fig. 3 (a)) of filling.That is to say,, repeat to form the color of starting point or end point at least, can describe the gray scale that the Drawing Object utilization has an above-mentioned filling effect by at least one side of above-mentioned starting point and end point and then.Perhaps, also can only repeat a part of pattern of the gray scale between starting point and the end point and form.
In addition, the gray scale between this starting point and the end point is repeated, then can realize the effect (with reference to Fig. 3 (b)) that repeats if describing beyond between starting point and the end point be thought of as.At least one square one-tenth starting point of promptly and then above-mentioned starting point and end point and the gray scale between the end point can be carried out describing of repetition gray scale to Drawing Object with this.
Have again, the gray scale between this starting point and the end point is alternately repeated on the contrary, then can realize the effect (with reference to Fig. 3 (c)) that reflects if describing beyond between starting point and the end point be thought of as.At least one square one-tenth of promptly and then above-mentioned starting point and end point makes the pattern of the gray inversion between starting point and the end point, can carry out gray scale to Drawing Object with this and replace describing of reversally repeating.
In addition, generate in the step in above-mentioned greyscale pattern, there is no particular limitation to describing of carrying out of the pixel beyond the position corresponding with the gray scale vector of basic greyscale pattern.For example, if the greyscale pattern of the color that exists beyond between the starting point of the basic greyscale pattern of employing and the end point is described, then Drawing Object is just described with the polychrome gray scale.
Promptly have the basic greyscale pattern of reference point more than three looks (different multiple colors, preferably three color bases on schedule) mutually, Drawing Object is described, can form the polychrome gray scale with this as the reference point of the look of gray scale by employing.
In existent method, polychrome gray scale for the reference point that has color with starting point and the color beyond the end point color between the vector starting point that is implemented in the gray scale vector and the vector end point, must be unit with the pixel, repeat two color shades repeatedly and handle.
But, in the present invention,, therefore, then, just can cut down calculated amount subsequently as long as copy step repeatedly if having finished the polychrome gray scale at ground floor handles owing to adopt the basic greyscale pattern of reference point as mentioned above with 3 looks.
Various embodiments of the present invention are described below successively.
＜horizontal (level) gray scale: embodiment 1 〉
Embodiment 1 shown below, be to adopt the present invention, for example shown in Fig. 4 (b), to using coordinate figure (0,0), (150,0), (150,100), to describe the vector starting point of gray scale vector be the redness of coordinate figure (0,0) to the Drawing Object that surrounds of the rectangle of (0,100), the vector end point is the gray scale of the blueness of coordinate figure (150,100).That is, the rectangle of the Drawing Object of present embodiment is the bounding rectangle with each limit of along continuous straight runs and vertical direction.
The direction of this gray scale vector (change direction of the color of gray scale or concentration etc.) be the lower right different with horizontal direction and vertical direction to.Be that the gray scale style is in the horizontal direction and on the direction between the vertical direction.Fig. 4 (c) is depicted as Drawing Object is described basic greyscale pattern and the completed gray scale that obtains is described example.In this figure, the gray scale style is simplified expression.The actual gray scale style of describing is more high precision, the style of high definition more.In addition, Figure 5 shows that this control flow.
Shown in 5, generate in the step (step 1, below in the drawings S made in the step brief note) in greyscale pattern, differentiate boundary rectangle on one side long of Drawing Object.This is to reduce the temporary transient memory storing size used in the step (S1) as far as possible for example generates in greyscale pattern.
Consider that one side makes basic greyscale pattern skew one side describe (copy), to the longer sides of the boundary rectangle of Drawing Object, as long as temporarily store large-size, for example double the basic greyscale pattern of size.Under the situation of present embodiment 1, the two ends coordinate figure of temporarily storing the basic greyscale pattern of ground floor reaches the laterally basic greyscale pattern (Fig. 4 (a)) of (300,0) for (0,0).In addition, in the basic greyscale pattern shown in Fig. 4 (a), the color of coordinate (0,0) and (300,0) is the reference point of gray color.
Then, carry out describing of n floor (vertical direction promptly longitudinally n number).The initial value of n is set at 2 (S2).In this case, layer is a lateral type.In describing determining positions step (S3), " side-play amount " k of the basic greyscale pattern of the n layer of decision generating writing pattern object.According to the coordinate of the vector starting point and the vector end point of gray scale vector, because layer is horizontal, therefore (can obtain by the calculating of 100-0/ (150-0) * n|=|0.7n| by k=| for " side-play amount " k.That is, in the n layer (n 〉=2), the position of describing of basic greyscale pattern is (0.7n, 0).
Then, describe in greyscale pattern in (copy) step (S4), will be from the basic greyscale pattern of coordinate figure (0.7n, 0) to (150+0.7n, 0), shown in Fig. 4 (b), describe (copy) storage space from coordinate figure (0, n) to (150, n).
Then, judge that whether said n is (whether reaching) and i.e. 100 (S5) of the corresponding value of pixel of the vertical direction of the boundary rectangle of Drawing Object, said n is if not 100, the value increase by 1 of n (promptly is offset in vertical direction successively, S6), repeat above-mentionedly to describe determining positions step (S3) and gray scale is described (copy) step (S4), till n is 100, shown in Fig. 4 (b), repeat the copy of basic greyscale pattern.
By like this, shown in Fig. 4 (c), the direction that can access the gray scale vector be the lower right to gray scale describe example.
＜vertical (vertically) gray scale: embodiment 2 〉
The direction of this gray scale vector become the lower right to.Be that the gray scale style is the direction between horizontal direction and the vertical direction.Fig. 6 (c) is depicted as Drawing Object is described basic greyscale pattern and the completed gray scale that obtains is described example.In this figure, the gray scale style is simplified expression.The actual gray scale style of describing is more high precision, the style of high resolution more.In addition, Figure 7 shows that this control flow.
At first, generate in the step (S11), differentiate the long limit of the boundary rectangle of above-mentioned Drawing Object in greyscale pattern.Differentiate the result according to this, identical with the foregoing description 1, under the situation of present embodiment 2, the two ends coordinate figure of temporarily storing the basic greyscale pattern of ground floor is depicted as the basic longitudinally greyscale pattern of (0,0), (0,300) as figure (a).In addition, in the basic greyscale pattern shown in Fig. 6 (a), the color of coordinate (0,0), (0,300) is the reference point of gray color.
Then, carry out describing of n floor (horizontal direction being horizontal n number).The initial value of n is set at 2 (S12).In this case, layer is a longitudinal type.In describing determining positions step (S13), " side-play amount " k of the basic greyscale pattern of the n layer of decision depiction Drawing Object." side-play amount " k is according to the coordinate of the vector starting point and the vector end point of gray scale vector, because layer is longitudinally, therefore " side-play amount " k can obtain by the calculating of k=| (100-0)/(150-0) * n|=|0.7n|.Promptly the basic greyscale pattern of n layer (n 〉=2) describe (copy) position for (0,0.7n).
Then, describe in greyscale pattern in (copy) step (S14), will from coordinate figure (0,0.5n) to (0, basic greyscale pattern 150+0.5n) describe (copy) storage space from coordinate figure (n, 0) in (n, 150).
Then, judge whether said n becomes (whether reaching) and the boundary rectangle of Drawing Object is 100 (S15) in the corresponding value of pixel of horizontal (level), said n is if not 100, then make the value of n increase by 1 (i.e. skew successively in the horizontal, S16), repeat above-mentionedly to describe determining positions step (S13) and gray scale is described (copy) step (S14), become till 100 up to n, shown in Fig. 6 (b), repeat the copy of basic greyscale pattern.
By like this, shown in Fig. 6 (c), the direction that can access the gray scale vector be the lower right to gray scale describe example.
＜polychrome gray scale: embodiment 3 〉
Generate in the step (S1) in greyscale pattern, generate basic greyscale pattern.Under the situation of present embodiment 3, temporarily store the laterally basic greyscale pattern that the 1st layer the two ends coordinate figure of basic greyscale pattern such as Fig. 8 (a) are depicted as (0,0), (300,0).In addition, in the basic greyscale pattern shown in Fig. 8 (a), the color of coordinate figure (0,0), (150,0), (300,0) is the reference point of gray color.
Then, identical with the control flow of embodiment 1 described Fig. 5, shown in Fig. 8 (b), step of replotting determining positions successively (S3) and gray scale are described (copy) step (S4), can describe the gray scale style of 3 looks like this to this Drawing Object.
Fig. 8 (c) is depicted as Drawing Object is described the resulting example of finishing of above-mentioned basic greyscale pattern.In this figure, the gray scale style is simplified expression.The actual gray scale style of describing is more high precision, the style of high definition more.Handle equally, also can realize 4 looks or the polychrome gray scale more than 4 looks with identical method.
The processing of＜end points: embodiment 4 〉
Describe example shown in Fig. 9 (c), be to adopt the present invention, to using coordinate figure (0,0), (150,0), (150 shown in Fig. 9 (b), 100), (0,100) Drawing Object that rectangle surrounds is shown in Fig. 9 (a), for the zone beyond between the starting point of basic greyscale pattern and the end point, carry out being coated with the color of starting point in starting point one side full, and the gray scale style of end point one side when being coated with full processing (filling processing) with the color of end point describe example.Shown below is this embodiment 4.In addition, about its control flow, because identical with Fig. 5, so detailed.
In addition, the processing to the zone beyond between the starting point of above-mentioned basic greyscale pattern and the end point is not limited to above-mentioned filling and handles.For example, greyscale pattern generate basic greyscale pattern that step (S1 of Fig. 5) generates also can be with above-mentioned starting point and end point between beyond the zone, shown in Figure 10 (a), repeat the re-treatment of the gray scale between above-mentioned starting point and the end point.Identical with embodiment 1, describe (copy) step (S4 of Fig. 5) by such replotting determining positions step (S3) and gray scale shown in Figure 10 (b), can describe the greyscale pattern gray scale repeatedly shown in Figure 10 (c).
Have again, as another variation, generating basic greyscale pattern that step (S1) generates in greyscale pattern also can be shown in Figure 11 (a), replace the opposite reflection processing that repeats the gray scale between this starting point and the end point beyond between starting point and the end point.Also identical in this case with embodiment 1, describe (copy) step (S4) by such replotting determining positions step (S3) and gray scale shown in Figure 11 (b), can describe the gray scale of the greyscale pattern reflection shown in Figure 11 (c) with this.
The manual input that＜basic greyscale pattern generates (from the outside input): embodiment 5 〉
Figure 12 shows that the situation of manual input of passing through with basic greyscale pattern input as embodiment 5.When the basic greyscale pattern of manual input shown in Figure 12 (a), the gray scale about the Drawing Object that adopts this basic greyscale pattern shown in Figure 12 (b), becomes gray scale style arbitrarily.Like this, can access the strong gray scale style of visual effect.
The manual input of other of＜basic greyscale pattern: embodiment 6 〉
Make " side-play amount " that Figure 13 (a)～Figure 13 (c) is depicted as embodiment 6 depends on the situation of y axle (vertical direction) position (making it as the parameter subordinate) of Drawing Object.In the figure, shown in Figure 13 (b), more towards the pars intermedia of Drawing Object, then the basic greyscale pattern shown in Figure 13 (a) to the right " side-play amount is " big more.So, shown in Figure 13 (c), can access the gray scale style of the strong Drawing Object of visual effect.
Like this, image processing method of the present invention is to be coated with in the full image processing method with the gray scale style on to Drawing Object, and the greyscale pattern with basic greyscale pattern of the some directions that generate horizontal direction or vertical direction generates step; And one side makes the direction skew of the basic greyscale pattern of above-mentioned greyscale pattern generation step generation along this basic greyscale pattern, the copy step of the direction replotting that the one side edge is vertical with this direction.
Generate in the step in above-mentioned greyscale pattern, on storer, only describe one deck share (ground floor) of the beginning of benchmark greyscale pattern in advance.At this moment, when generating reference point as the color of the benchmark of gray color and have only the such simple greyscale pattern of the end look of the beginning look of starting point of basic greyscale pattern and end point, also can calculate existing computing method gray scale, that treatment capacity is big to each pixel.That is, as long as the interpolation processing of the difference of the pixel grey scale of pixel grey scale by removing starting point with the distance of starting point and end point and end point determines the gray scale of each pixel to get final product.By like this, can reduce calculated amount, alleviate computing.
For example, establish three the pixels formations of each pixel by R (red), G (green), B (indigo plant), the value of each pixel is got the some values between 0～255.In this case, white become (R, G, B)=(255,255,255), black become (R, G, B)=(0,0,0).
Coordinate figure in the starting point of benchmark greyscale pattern is (0,0), and color is red (255,0,0), the coordinate figure of end point is (100,0), color is blue (0,0,255), when between them, generating greyscale pattern, distance between starting point and the end point is 100, removes pixel value poor of the pixel value of starting point and end point with this distance 100, and the every distance that obtains like this is that 1 increment becomes 2.55.Thereby the value of the color of coordinate figure (P, 0) is (255-2.55 * P, 0,2.55 * P).
Like this, even calculating formula that need not be complicated also can be calculated the color of the gray color of each pixel, can reduce computing.
Describe in (copy) step in above-mentioned gray scale, since can will be in advance between the storer that the greyscale pattern utilization calculating function of describing on the storer of computing machine is carried out at a high speed copy function copy, therefore compare with the method for each pixel being calculated and describe, speed improves greatly.
In addition, the number of times that repeats to copy step is many more, and then to account for full-time ratio more little the rise time of greyscale pattern, and the effect of high speed is remarkable more as can be seen.Therefore, even complicated calculating is carried out in the generation of greyscale pattern, and in image processing method of the present invention, also very little to the influence that its processing speed reduces.
Another image processing method of the present invention is that Drawing Object is being coated with in the full image processing method with the gray scale style, and the greyscale pattern that comprises the basic greyscale pattern of the some directions that generate horizontal direction or vertical direction generates step; According to the direction of basic greyscale pattern and along the distance of the direction vertical with basic greyscale pattern direction try to achieve " side-play amount " and decision describe the starting position describe the determining positions step; And describe step from the above-mentioned greyscale pattern of describing to describe along above-mentioned basic greyscale pattern direction the starting position, repeat above-mentioned determining positions step and the copy step described.
Above-mentioned greyscale pattern generates step according to parameters such as the position of the color of gray scale starting point and end point, Drawing Object and times, generates greyscale pattern automatically, or is taken into the figure of manual input, by also reaching the requirement of above-mentioned problem like this.
Generate in the step in above-mentioned greyscale pattern, when describing ground floor, to utilize this gray scale to be coated with the position of full Drawing Object existence, the coordinate on each summit and the position relation of other Drawing Object, as the subordinate variable of " side-play amount ", by realizing the strong gradation effect of expressive force such as wavy gray scale like this.
In addition, beginning look, control information and above-mentioned parameters such as end look, starting point and end point by from its generation of external control can access the person-machine dialogue effect.
