Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
Fig. 1 is a kind of method flow diagram for adjusting text importing image provided in an embodiment of the present invention.It is of the invention real
Applying the method for the adjustment text importing image of example offer can realize in mobile phone, PAD, notebook computer or PC etc.
On terminal device.The flow of adjustment text importing image in the present embodiment as shown in Figure 1 can include：
Step S110, obtains Target Photo and the corresponding text importing region of the Target Photo.
Specifically, terminal can promote news for every in advance sets corresponding picture and word, when getting user
For the corresponding click commands for promoting news of the Target Photo, or, reach that the display Target Photo is corresponding and promote
The display cycle of information, terminal then obtains the Target Photo and the corresponding text importing region of the Target Photo.
Wherein, the text importing region is used to show the corresponding word of the Target Photo, the text importing region
Particular location on the Target Photo, the present invention is not limited.
Step S120, obtains the colour of at least one sampled point in the Target Photo.
In RGB color pattern, color is mixed by red, green, blueness, and colour represents color in RGB color mould
Corresponding value in formula, for example, red corresponding value in RGB color pattern is 255,0,0；Green is in RGB color pattern
In corresponding value be 0,255,0；Blueness value corresponding in RGB color pattern is 0,0,255.
Specifically, when terminal gets Target Photo, terminal can obtain at least one in the Target Photo and adopt
The colour of sampling point.
Wherein, the sampled point acquired can be evenly distributed on the Target Photo, for example, by Target Photo
Four regions are evenly dividing into, a sampled point is obtained in each area, wherein, the quantity in the region of division and each
The quantity for the sampled point that region is obtained, the present invention is not limited.
Optionally, terminal can be sampled for Target Photo with text importing region lap, so that described
The colour of at least one sampled point is obtained in the lap of Target Photo, with the tone energy in the text importing region finally determined
It is enough close with the tone of Target Photo lap.
Step S130, according to the colour of the sampled point acquired, determines the tone of the Target Photo.
Tone can be determined in terms of form and aspect H (Hue), Reinheitszahl S (saturation) and lightness B (brightness) three
Justice, i.e., represented with HSB values, for representing the general inclination in certain color, such as partially blue, partially red, partially warm or colder, its
In, the maximum of form and aspect is 255, and the maximum of Reinheitszahl is 100%, and the maximum of lightness is 100%.
As an alternative embodiment, terminal can be according to the colour of the sampled point acquired, described
Reference sample point is determined in each sampled point, further according to the colour of the reference sample point, the tone of the Target Photo is determined.
In the specific implementation, terminal can calculate the pure of each sampled point according to the colour of acquired obtained sampled point
Angle value S, the reference sample point is defined as by the sampled point of the Reinheitszahl maximum for calculating and obtaining；Or, terminal can be by
Any one sampled point of Reinheitszahl S in the range of default Reinheitszahl is defined as the reference sample point；Terminal is further according to described
The colour of reference sample point, determines the tone of the Target Photo, optionally, and terminal can be according to the conversion of rgb value to HSB values
Relation, determines the tone of the Target Photo.
Wherein, the form and aspect H that terminal calculates Target Photo according to rgb value may be referred to below equation：
H=(0+ (G-B)/(MAX-MIN)) * 60, IF R=MAX；
H=(2+ (B-R)/(MAX-MIN)) * 60, IF G=MAX；
H=(4+ (R-G)/(MAX-MIN)) * 60, IF B=MAX；
Terminal can calculate the purity of sampled point according to maximum in rgb value and the difference and the ratio of maximum of minimum value
Value, for example, the rgb value of sampled point is 0,255,180, the Reinheitszahl of the sampled point is equal to 100% according to knowable to calculating.
The ratio of maximum in rgb value and 255 can be defined as lightness B by terminal, for example, rgb value is 0,90,200,
So, maximum is 200, then brightness value B is 200/255=0.784=78%.
As another optional embodiment, if terminal obtains at least two sampled points in the Target Photo
Colour, then terminal the pure of each sampled point can be calculated according to the colours of at least two sampled points acquired

Tone.
Optionally, terminal can determine one in the interval of the colour between first sampled point and the second sampled point
Individual colour, the tone of the Target Photo is determined according to the colour determined.For example, between the first sampled point and the second sampled point
Colour interval be 10-110,35-75,65-200, then terminal a colour can be determined in the interval value, for example
56,70,100 or 80,40,150 etc., terminal can determine the Target Photo according to colour and the transformational relation of tone
Tone.
Wherein, terminal can also the colour between first sampled point and the second sampled point it is interval in determine to
Few two colours, the multiple color tones of the Target Photo are calculated according to each colour correspondence determined.First sampled point with
Exemplified by interval still with 10-110, the 35-75 of colour between second sampled point, 65-200, terminal can be in the interval value
Determine at least two colours, such as 56,70,100,80,40,150 and 90,60,180 etc., terminal can calculate institute respectively
The corresponding tone of each colour is stated, the tone calculated is defined as to the tone of the Target Photo.
Step S140, according to the tone of the Target Photo, adjusts the tone in the text importing region.
Specifically, if terminal only determines a kind of tone of the Target Photo, terminal can be by the text importing area
The hue adjustment in domain is the tone of the Target Photo；If terminal determines at least two tones of the Target Photo, terminal
The tone in the text importing region can be adjusted with reference to the multiple color tones of the Target Photo, i.e., according to the target figure determined
The number of the tone of piece is by text importing region division into different region parts, and the tone of different zones part is different.
Further alternative, terminal can also control the gradation of hue in the text importing region, that is, control the word
The tone of viewing area gradually becomes shallower as or gradually deepened etc..
