Fig. 2 is the process flow diagram of a kind of image processing method of providing of the embodiment of the invention.Referring to Fig. 2, described method comprises:
201, take pixel as unit, the Target Photo in the viewing area is split, obtain a plurality of pixels.
In embodiments of the present invention, Target Photo is the main picture of the need configuration background colour in the viewing area.Viewing area for different application, its corresponding Target Photo can be different, as, for the business card in the address list, Target Photo is head portrait picture, for voice applications, Target Photo can be the album cover picture, and for news website, Target Photo can be a topic picture, and the not corresponding usefulness of the embodiment of the invention and Target Photo are enumerated one by one.
Business card viewing area in only take the viewing area as address list, be that example describes and Target Photo is head portrait picture in the business card, then this step 201 specifically comprises: take pixel as unit, the head portrait picture in the business card viewing area is split, obtain a plurality of pixels of this head portrait picture.
Need to prove, because Target Photo may be a picture compress or amplifies processing according to original image after, when therefore Target Photo being split, can carry out according to the resolution of original image corresponding to this Target Photo, also can carry out according to the current resolution of Target Photo.
202, according to default account form, obtain volume coordinate corresponding to described a plurality of pixel.
Wherein, described default account form is YUV or RGB mode.
Particularly, use YUV or RGB mode, be a plurality of pixel assignment of this Target Photo, each pixel is as a point in the three dimensions, as shown in Figure 3, Fig. 3 is the schematic diagram of the respective coordinates position of a certain pixel in coordinate system that provide of the embodiment of the invention.
Need to prove, according to different account forms, the volume coordinate that calculates may be different, and the embodiment of the invention is not done concrete restriction to this.
203, calculate distance between the volume coordinate of each pixel in each benchmark color and the described a plurality of pixel.
Wherein, the number of benchmark color and concrete corresponding color can be specified in advance, as, the benchmark color can have four kinds, is respectively red, yellow, orange, green.Need to prove, the number of the benchmark color that sets in advance is more, and the color matching effect of finally carrying out according to voting results is better.
Every kind of benchmark color has corresponding volume coordinate (as shown in Figure 4) in three dimensions, this volume coordinate can be the volume coordinate of calculating according to YUV or RGB mode, and its concrete account form need to be consistent with the account form of pixel volume coordinate.
204, according to the distance size between the volume coordinate of each pixel in each benchmark color and the described a plurality of pixel, described each benchmark color is voted.
Particularly, according to the distance size between the volume coordinate of each pixel in the volume coordinate of each benchmark color and a plurality of pixel, this distance can be air line distance, each pixel is according to the distance size between the volume coordinate of this pixel and each benchmark color, the nearest benchmark color with this pixel is given in ballot, so just obtain the voting results of a color proximity, for example: as shown in Figure 5, Fig. 5 is the schematic diagram that pixel is voted to the benchmark color, only shows the voting process of partial pixel point among this figure.In N the pixel 50% the approaching green of point is arranged, 40% point approaches yellow, and 10% point approaches redness, and wherein, N is integer.
When the viewing area is business card in the address list, this Target Photo is head portrait picture, for head portrait picture, personage's face and hair appears in possible greater probability, when calculating ballot, the black of the colour of skin and hair can be removed, correspondingly, the step 204 of this embodiment of the invention specifically comprises: get rid of the first pixel in described a plurality of pixel, described the first pixel is that described Target Photo characterizes the colour of skin and pixel corresponding to color development part; Distance size according to described each benchmark color and between the volume coordinate of the second pixel in the described a plurality of pixels after getting rid of, described each benchmark color is voted, and described the second pixel is to characterize the colour of skin and pixel pixel in addition corresponding to color development part in described a plurality of pixel.
Wherein, the part that characterizes the colour of skin and color development can be determined according to the color value of pixel.
205, according to the number of votes obtained of each benchmark color after the ballot, determine the benchmark color with described Target Photo coupling.
When pixel ballot is finished, compare according to the number of votes obtained of each the benchmark color after the ballot, the benchmark color that number of votes obtained is the highest is defined as the benchmark color with this Target Photo coupling.As, based on the example of step 204, in N the pixel 50% the approaching green of point being arranged, 40% point approaches yellow, and the approaching redness of 10% point is green with the benchmark color that this Target Photo mates then.
Alternatively, described step 205 specifically comprises: according to the weight of number of votes obtained and the ballot pixel of each benchmark color after the ballot, calculate the correction poll of each benchmark color; According to the correction poll of described each benchmark color, determine the benchmark color with described Target Photo coupling.
Wherein, the weight of ballot pixel can be determined according to color shared area ratio in this Target Photo corresponding to ballot pixel.
The color (such as black) that occurs in a big way in the target image (such as contact head image) may affect final realization effect), when ballot, can give lower weight, the large tracts of land influence of color is whole to be judged in case cross.
Still based on the example of step 204, in N the pixel 50% the approaching green of point is arranged, 40% point approaches yellow, 10% point approaches red, wherein, this 50% pixel that approaches green all is positioned at the same area, and should surpass 50% by zone shared area ratio in Target Photo, then be that the ballot weight of this pixel of 50% is composed lower value, such as 0.5, then at this moment, reduce to 25% according to 50% after the weight adjustment, according to the correction poll after adjusting, can determine to approach yellow point and account for 40%, therefore large percentage determines that yellow is the benchmark color of mating with Target Photo.
Alternatively, described step 205 can also specifically comprise: according to the number of votes obtained of each benchmark color and the weight of described each benchmark color after the ballot, calculate the correction poll of each benchmark color; According to the correction poll of described each benchmark color, determine the benchmark color with described Target Photo coupling.
Wherein, the weight of each benchmark color can be determined according to the number of votes obtained of this benchmark color, the ratio that the number of votes obtained of a certain benchmark color accounts for aggregate votes surpasses predetermined threshold value, then the weight with this benchmark color is adjusted into 0, as, know that through ballot the number of votes obtained of benchmark color black accounts for 80% of aggregate votes, surpass predetermined threshold value 50%, then the weight with this benchmark color is adjusted into 0, the impact of avoiding large-area inclined to one side black that color matching is caused.
206, according to the benchmark color of described Target Photo coupling and the background colour corresponding to benchmark color of described coupling, color filling is carried out in the background area of described viewing area.
Terminal equipment configuration has the background colour with each benchmark color-match, to obtain abundanter color matching effect, when determining the benchmark color of coupling, obtains corresponding with it background colour according to the benchmark color of determining.For example: reference color are yellow, and are the most good-looking under pitch black color matching, therefore set up the corresponding relation between reference color yellow and the aterrimus, when definite reference color are yellow, according to aterrimus color filling carried out in the background area of described viewing area.
In embodiments of the present invention, only to determine background colour by terminal device, and be filled to example according to background colour and describe, and in fact, in order more to be adapted to user's visual custom and aesthetic requirement, terminal device can be determined at least a background colour according to the current goal picture, and should offer user selection by at least a background colour, according to the background colour of user selection the background area of viewing area is filled.This background colour includes but not limited to the complementary colors of benchmark color etc.
