Abstract
The invention provides an icon and text processing method. The method comprises the following steps: acquiring a desktop wallpaper image and extracting a color value of the wallpaper image; calculating average brightness of the wallpaper image through the color value, judging whether the average brightness is greater than a set brightness value or not, judging that the wallpaper image is bright wallpaper and changing icons and texts into deep color if the average brightness is greater than the set brightness value, and otherwise, performing judgment of a next step; judging whether the saturation degree of the wallpaper image is low according to the brightness distribution situation of the wallpaper, changing the icons and the texts into white color and superimposing deep shade if the saturation degree of the wallpaper image is low, otherwise, changing the icons and the texts into white color and superimposing light shadow to enable the icons and the texts to intelligently recognize the color of background wallpaper, and automatically adjusting the color and the shadow of the font per se to highlight the text content.
Description
Technical field
The present invention relates to technical field of image processing, be specifically related to a kind of icon literal processing method.
Background technology
The icon word of existing mobile terminal desktop can only carry out Show Color according to the setting of system, the color of image of background wallpaper can not be identified, automatically color can not be adjusted according to the wallpaper color of background, to highlight word content, neither intelligence, also not humane, the individual demand of user can not be met.
Summary of the invention
Object of the present invention, overcomes the deficiencies in the prior art exactly, provides a kind of color of icon word energy Intelligent Recognition background wallpaper, and automatically adjusts color and the shade of self font, can highlight the icon literal processing method of word content.
In order to achieve the above object, adopt following technical scheme: a kind of icon literal processing method, said method comprising the steps of:
S10, acquisition desktop wallpaper image, extract the color value of wallpaper image;
S20, calculated the mean flow rate of wallpaper image by color value, judge whether mean flow rate is greater than predetermined luminance value, be if so, judged to be bright wallpaper, icon word becomes dark color; If not, then carry out next step to judge;
S30, judge that whether the saturation degree of wallpaper image is on the low side according to the lightness distribution situation of wallpaper, if so, icon word becomes white, and superposition dark-shaded, if not, icon word becomes white, superposes light shade.
Further, the concrete steps extracting the color value of wallpaper image in described step S10 are: by the pixel of predetermined interval traversal wallpaper image.
Preferably, described predetermined interval is 3 ~ 4 pixel separation.
Preferably, in described step S20, calculated the mean flow rate of wallpaper image by color value, judge that the concrete steps whether mean flow rate is greater than predetermined luminance value are:
S21, for each pixel traversed, get R, G, B value of its color, carry out weighted sum computing after each R, G, B value is multiplied by default weight respectively, the value of gained is as the brightness value of this pixel; Calculate the mean value of each pixel brightness value, the value of gained is as the mean flow rate A of image; Judge whether A is greater than predetermined luminance a value, if so, enters step S22; If not, then step S30 is entered;
S22, ask the variance vr of all pixel R values respectively, the variance vg of all pixel G values, and the variance vb of all pixel B values; Judge variance vr respectively, whether vg, vb are less than preset value, if all, be then judged to be bright wallpaper, icon word becomes dark word; If any one not, then enters step S30.
Preferably, judge that the saturation degree of wallpaper image concrete steps whether on the low side are according to the lightness distribution situation of wallpaper in described step S30:
S31, at least one pair of data default, often pair of data preset a brightness value and a ratio value;
S32, process each to data one by one, for process this to data, statistics exceedes the quantity of the pixel of predetermined luminance value, obtain the ratio of this quantity and total pixel number amount, judge whether this ratio value is greater than preset ratio value, if, be judged as low saturation wallpaper, icon word becomes white, superposition dark-shaded, and exits the treatment step to data; If not, proceed next to data processing, until find ratio value to be greater than the data of preset ratio value, if all data do not meet, then terminate the treatment step to data, icon word becomes white, superposes light shade.
Further, the opacity value of described light color is less than 40%, and the opacity value of described dark color is greater than 40%.
Compared with prior art, beneficial effect of the present invention is: the present invention, by obtaining desktop wallpaper image, extracts the color value of wallpaper image; Calculated the mean flow rate of wallpaper image by color value, judge whether mean flow rate is greater than predetermined luminance value, be if so, judged to be bright wallpaper, icon word becomes dark color; If not, then carry out next step to judge; Judge that whether the saturation degree of wallpaper image is on the low side according to the lightness distribution situation of wallpaper, if, icon word becomes white, superposition dark-shaded, if not, icon word becomes white, superposes light shade, make the color of icon word energy Intelligent Recognition background wallpaper, and automatically adjust the color of self font and shade so that the icon literal processing method of word content can be highlighted.
