Alternatively, described parameter needn't obtain from each provenance, but can in proper range, be generated randomly by micro-effect generation method of the embodiment of the present invention.Micro-effect generation method of the embodiment of the present invention can utilize any random digit generation method to generate described parameter, is not described in detail in this.
In addition, the time period of described predetermined timing and described micro-the effect of generation can, by the system default setting, also can be arranged arbitrarily by the user as required.
Step S103: present image according to described parameter and described micro-, generate target image.
Particularly, according to described parameter and described micro-each original pixel value presented in image, obtain corresponding each target pixel value in target image, thereby generate target image.Alternatively, according to described parameter, at each, regularly generate intermediate image, described intermediate image and described micro-present image combining, thereby generate target image.Predetermined each target image that regularly generates of each within the described time period, micro-of jointly having formed with micro-effect of described each target image presents image.

Micro-effect generation method of the embodiment of the present invention described in more detail below with reference to Fig. 2.
Referring to Fig. 2, Fig. 2 is the process flow diagram that is shown in further detail the processing of the step S103 in micro-effect generation method shown in Fig. 1.
Particularly, the step of described generation target image can comprise the steps:
Step S201: according to described parameter, calculate the mapping relations between the coordinate of micro-coordinate that presents the original pixels in image and the object pixel in target image.
Particularly, for each coordinate in target image, according to described calculation of parameter, go out at this coordinate place (, corresponding with this coordinate) object pixel corresponding to micro-which original pixels presented in image, and then obtain the coordinate of this original pixels in micro-presents image, therefore obtained the mapping relations between the coordinate of micro-coordinate that presents each original pixels in image and each object pixel in target image.
Step S202: the value that obtains the original pixels corresponding with the coordinate of described original pixels.
Particularly, in the situation that obtain described micro-from storer, present image, for micro-each coordinate presented in image, obtain the memory address of the storage original pixels corresponding with this coordinate, and read the original pixel value of this memory address place storage.Alternatively, in the situation that obtain described micro-from external source, present image, also can directly obtain the value of the original pixels corresponding with the coordinate of described original pixels.
Step S203: according to value and the described mapping relations of described original pixels, generate the value of the object pixel corresponding with described original pixels, thereby obtain described target image.
Particularly, for each object pixel in target image, value according to the mapping relations between the coordinate of the coordinate of this object pixel calculated at step S201 and original pixels and the corresponding original pixels of the coordinate with original pixels that obtains at step S202, micro-value that presents the original pixels at coordinate place in image, corresponding with the coordinate of this object pixel is made as to the value of this object pixel, thereby obtains described target image.Each within the described time period is predetermined regularly generates each target image, and each target image generated within the described time period has formed described micro-effect jointly.
In the processing of above-mentioned generation target image, according to the parameter regularly obtained at each, directly by micro-, present image mapped to target image, that is to say, regularly directly revise micro-and present image to obtain each target image, micro-of forming with micro-effect of each target image presents image at each.Alternatively, described target image can generate in the following manner: regularly according to the parameter obtained, form each intermediate image, micro-presents image and remains unchanged simultaneously at each, by micro-, presents image and each intermediate image combines to obtain each target image.In this mode, described each intermediate image has formed micro-effect, and described micro-presents image and described micro-combination of effects, thereby micro-of forming with micro-effect presents image.Alternatively, can be combined with above-mentioned two kinds of modes that generate target image.
Below, three micro-the different effects of take are more specifically described micro-the effect generation method according to the embodiment of the present invention as example.
In the first example, micro-the effect that generate is water ripples.
For generating micro-effect of water ripples, obtain micro-and present image.Described micro-presents storer built-in the electronic equipment that image can be applied to from described micro-effect generation method and obtains, also can obtain from outside.
In addition, in each predetermined parameter that regularly obtains.As mentioned above, in the case, described parameter for example can comprise the radius r of ring in water ripples and the width D of water ripples.Be noted that described parameter is not limited to the radius of ring in water ripples and the width of water ripples.Those skilled in the art can utilize other parameters fully, and such as the radius of water ripples inner and outer ring, the diameter of water ripples inner and outer ring, the girth of water ripples inner and outer ring etc. generates micro-of water ripples.The time period of generating widget effect, that is, the interval between last timing and first regularly for example is made as 1 minute.Interval between two adjacent predetermined timings for example is made as 30ms.Obviously, those skilled in the art can be made as arbitrary value by the interval between described time period and described two adjacent predetermined timings as required.
Preferably, in described each predetermined timing, upgrade described parameter.For example, at each, predetermined regularly the radius r of encircling in water ripples is increased progressively to 4 pixels, and by the width D of water ripples 1 pixel of successively decreasing.Those skilled in the art can arrange the above-mentioned amount that increases progressively and successively decrease according to actual needs, and in addition, those skilled in the art can arrange various update modes according to actual needs, within it is included in scope of the present invention.
In addition, described parameter can obtain from outside, also can alternatively with random fashion, generate.For example, in water ripples, the radius r of ring is the random value between 10 pixel to 30 pixels, and the width D of water ripples is the random value between 10 pixel to 50 pixels.Those skilled in the art can according to actual needs, utilize any random number generating mode to generate the random value in proper range, within it is included in scope of the present invention.
After this, according to micro-of water ripples, present the radius r encircled in image and water ripples and the width D of water ripples, generate the target image of water ripples.
Particularly, according to the width D of the radius r of encircling in water ripples and water ripples, by following formula (1), to (3), calculate the mapping relations between the coordinate of micro-coordinate that presents the original pixels in image and the object pixel in target image:
x1＝RT×x (1)
y1＝RT×y (2)
Wherein, as mentioned above, the radius that r is ring in water ripples, the width that D is water ripples, in addition, the coordinate that (x1, y1) is original pixels, (x, y) be the coordinate of object pixel, RT is scale-up factor, and u is the constant between 0 to 1, such as being 0.2,0.5 etc.
Thus, the mapping relations between the coordinate of micro-coordinate that presents the original pixels in image and object pixel in target image have been calculated.
Alternatively, in practice, for reducing divide operations further to improve operation efficiency, can utilize table lookup operation, particularly, the table lookup operation to sine table well known to those skilled in the art (SIN table) and reciprocal table (DIV table) substitutes above formula (3) with following formula (4):
RT＝sin(SIN_RANGE×DIV[2×r+D]×DIV[D]×(x
2+y
2-r
2)) (4)
Wherein, SIN_RANGE is a constant, in this example, and SIN_RANGE=512.In addition, DIV is for asking operation reciprocal.
In addition, in (3), meet following relation at above-mentioned formula (1) between the horizontal ordinate x of object pixel and the scope of ordinate y:
When the scope of y is [0, r], the scope of x is
When the scope of y be (r, r+D] time, the scope of x is
After this, obtain the value of the original pixels corresponding with the coordinate of described original pixels.
Particularly, for example, in the situation that micro-present during image is stored in storer, the address A (x1, y1) that stores original pixels (x1, y1) in storer for example obtains by following formula (5):
A(x1，y1)＝y1×W×A
pixel+x1 (5)
Wherein W is for take micro-the width that presents image that pixel is unit, A
pixelit is a storage space that pixel is shared.
Thus, at the memory address place that utilizes the coordinate of original pixels, obtains by above formula (5), read the value of original pixels.
After this, according to value and the described mapping relations of described original pixels, generate the value of the object pixel corresponding with described original pixels, thereby obtain described target image.
Particularly, the address A (x, y) that stores object pixel (x, y) in storer for example passes through following formula (6) acquisition:
A(x，y)＝y×W×A
pixel+x (6)
Wherein, as mentioned above, W is for take micro-the width that presents image that pixel is unit, A
pixelit is a storage space that pixel is shared.
Value according to the mapping relations between the coordinate of the coordinate of this object pixel calculated to (3) by above formula (1) and original pixels and the original pixels that reads by aforesaid operations, the value of this original pixels is write to the object pixel (x obtained by above formula (6), y) memory address, thereby the value of generation object pixel.
Each object pixel is carried out to above-mentioned processing, thereby obtain described target image.
Alternatively, described target image can generate in the following manner: within the whole time period that generates micro-effect of described water ripples, described micro-presents image and remains unchanged.In addition, each within the described time period regularly, according to the radius r of encircling in the water ripples that obtain and the width D of water ripples, generates intermediate image.In the case, described intermediate image is a ring-type image.After this, present image and each intermediate image combines in the mode for example superposeed by described micro-, thereby obtain target image.
Alternatively, can be combined with above-mentioned two kinds of modes that generate target image.
Each within the described time period is predetermined regularly generates each target image, and each target image generated within this time period has formed micro-effect of described water ripples jointly.
In addition, preferably, can present image centered by the center of circle by micro-of water ripples, be divided into altogether four in the horizontal direction with on vertical direction, and only micro-effect generation of the above-mentioned water ripples of execution wherein processed, after this, utilize rotational symmetry and Central Symmetry to generate micro-effect of water ripples to other three.For example, the pixel coordinate on horizontal direction and vertical direction be on the occasion of piece carry out micro-effect of above-mentioned water ripples and generate and process after, for the pixel coordinate on horizontal direction, for the pixel coordinate on negative and vertical direction, be positive piece, can by with-x ,-x1 distinguishes substitution above formula (5) and (6) and generates micro-effect of water ripples.Those skilled in the art can carry out similarly and operate other two, to generate micro-effect of water ripples of corresponding blocks, thereby present image for whole micro-, generate micro-effect of water ripples.By above-mentioned processing, can further reduce treatment capacity, thereby raise the efficiency.
In addition, preferably, described micro-effect generation method can arrange the minimum widith D of water ripples
min.Described D
minvalue can be selected arbitrarily as required by those skilled in the art, for example can be by D
minbe made as 8 pixels.After the width D of water ripples is upgraded in each predetermined timing, compare D and D
minif, D<D
min, determine that micro-effect of water ripples generates processing and finish.
In addition, preferably, described micro-effect generation method can generate micro-effect of a plurality of water ripples in certain viewing area.In the case, described parameter also can comprise the centre coordinate of water ripples.Described centre coordinate can generate with random fashion.For example, the center horizontal ordinate of water ripples can be for 0 to the random value between the width W of viewing area, and the center ordinate of water ripples can be for 0 to the random value between the height H of viewing area.In addition, in the case, described micro-effect generation method can arrange the maximum quantity N of water ripples
max.Described N
maxvalue can be selected arbitrarily as required by those skilled in the art, for example can be by N
maxbe made as 10.Regularly predetermined at each, count current water ripples quantity N, and compare N and N
maxif, N=N
max, determine that micro-effect of water ripples generates processing and finish.
The above be take micro-effect of water ripples and micro-effect generation method of the embodiment of the present invention has been described as example.Preferably, micro-effect generation method of the embodiment of the present invention can realize in hardware based mode.Preserving with needs existing micro-the effect generation method that a plurality of images calculate target image compares, micro-effect generation method of the embodiment of the present invention only needs to utilize single micro-to present image and can calculate target image, greatly reduce the requirement to the hardware store ability, and generating widget effect efficiently, thereby reduced CPU usage.
In the second example, micro-the effect that generate is whirlpool.
With top the first example class seemingly, for generating micro-effect of whirlpool, obtain micro-and present image.Its processing is similar with the processing in above-mentioned the first example, is not described in detail in this.
In addition, in each predetermined parameter that regularly obtains.As mentioned above, in the case, described parameter for example can comprise size for H capable * the pixel-shift moment matrix M of W row, wherein H is for take micro-the height that presents image that pixel is unit, W is for take micro-the width that presents image that pixel is unit.Each element M in pixel-shift moment matrix M
h, wthe value representation coordinate be the corresponding side-play amount of pixel that (h, w) locates.Be noted that described parameter is not limited to the pixel-shift moment matrix.Those skilled in the art can utilize other parameters to generate micro-effect of whirlpool fully.
Preferably, in described each predetermined timing, upgrade described parameter.In the situation that this example, for upgrading described pixel-shift moment matrix, at first, obtain the anglec of rotation of pixel-shift moment matrix, and in each predetermined timing, the described anglec of rotation is increased progressively to θ, to obtain the anglec of rotation Φ after upgrading, wherein θ is micro-rotational speed that presents image, that is, rotation step-length.Wherein, rotation step-length and the anglec of rotation can obtain from outside, for example by those skilled in the art, are suitably arranged as required.Alternatively, described rotation step-length and the anglec of rotation also can generate with random fashion in proper range.After this, the anglec of rotation Φ based on after upgrading, each element of the pixel-shift moment matrix after upgrading by following formula (7) and (8) acquisition
with each element M in current pixel side-play amount matrix
xd, ydthe ranks coordinate between relation:
xd＝xd
up×cosΦ-yd
up×sinΦ (7)
yd＝yd
up×cosΦ+xd
up×sinΦ (8)
After this, by the element M in current pixel side-play amount matrix
xd, ydvalue be made as in the pixel-shift moment matrix after renewal and element M
xd, ydcorresponding element
value, thereby the pixel-shift moment matrix after being upgraded.
The update mode that it is pointed out that above-mentioned side-play amount matrix is only example, and those skilled in the art can arrange various update modes according to actual needs, within it is included in scope of the present invention.
In addition, with similar in above-mentioned the first example, in addition, described parameter can obtain from outside, also can alternatively with random fashion, generate.Those skilled in the art can according to actual needs, utilize any random number generating mode to generate the random value in proper range, within it is included in scope of the present invention.
After this, micro-according to whirlpool presents image and pixel-shift moment matrix, the target image of generation whirlpool.
Particularly, according to each element in the pixel-shift moment matrix, by following formula (9) and (10), calculate the mapping relations between the coordinate of micro-coordinate that presents the original pixels in image and the object pixel in target image:
x1＝x+xd (9)
y1＝y+yd (10)
The coordinate that wherein (x1, y1) is original pixels, the coordinate that (x, y) is object pixel, and (xd, yd) is corresponding to the side-play amount of pixel coordinate (x, y) in the side-play amount matrix.
Preferably, as calculate and coordinate (x object pixel, when y) coordinate of corresponding original pixels exceeds micro-width W that presents image or height H, by horizontal ordinate x1 with respect to micro-width W remainder that presents image, and by corresponding micro-the height H remainder that presents image of ordinate y1, finally obtain the coordinate (x1, y1) of the original pixels corresponding with the coordinate (x, y) of object pixel.
Thus, the mapping relations between the coordinate of micro-coordinate that presents the original pixels in image and object pixel in target image have been calculated.
After this, with similar in above-mentioned the first example, by above-mentioned formula (5), obtain the value of the original pixels corresponding with the coordinate of described original pixels.
After this, with similar in above-mentioned the first example, value according to the mapping relations between the coordinate of the coordinate of the object pixel calculated by above formula (9) and (10) and original pixels and the original pixels that reads by aforesaid operations, the value of this original pixels is write to the object pixel (x obtained by above formula (6), y) memory address, thereby the value of generation object pixel.Each object pixel is carried out to above-mentioned processing, thereby obtain described target image.
Alternatively, with similar in above-mentioned the first example, also can within the described time period, keeping micro-, to present image constant, and regularly according to described parameter, generate intermediate image at each, and it is superimposed that intermediate image and micro-are presented to image, thereby generate described target image.Perhaps, can be combined with these two kinds of modes and generate target image.
Each within the described time period is predetermined regularly generates each target image, and each target image generated within this time period has formed micro-effect of described whirlpool jointly.
Preferably, after each predetermined timing obtains described target image, for preventing the target image obtained according to the pixel-shift moment matrix, undergo mutation, can adopt suitable size as shown in Figure 3A (for example, 3 * 3 pixels) masking-out, target image is carried out to mean filter, remove the high fdrequency component in target image, make image become level and smooth.The method to set up of masking-out and the processing of mean filter operation are known to those skilled in the art, are not described in detail in this.It is pointed out that those skilled in the art can become smoothly image by any mode as required, within it is included in the scope of the invention.
