Fig. 2 is the flow chart of a kind of watermark adding method according to an exemplary embodiment, as in figure 2 it is shown, comprise the following steps:
In step 201, when detecting that user uses watermark function to take pictures, in the pending image that image taking window shows, obtain object region.
Wherein, object region is the region of watermark to be added.
In the disclosed embodiments, the camera of terminal has watermark and adds function, watermark can be added for the image of user's shooting, function is added in this watermark can give tacit consent to closedown, user can arrange the page at corresponding camera and open this watermark interpolation function, and the original state that this watermark is added function by disclosure embodiment does not specifically limit. Adding function by opening this watermark, user can choose the image that watermark to be added template is shooting in multiple watermark templates of storage and add watermark. Wherein, watermark template, for storing the information such as the font color of watermark, position to be added and watermark element, indicates watermark font color in pending image, viewing area and display content etc. Each watermark template can be the template comprising independent watermark element, such as individually comprises time watermark, weather watermark, mood watermark etc.; Each watermark template can be also the template comprising multiple watermark element, such as comprises one or more combinations such as time watermark, weather watermark, mood watermark, and the concrete watermark element comprised of each watermark template is not defined by disclosure embodiment.
When terminal detects user to the open operation of camera, detection watermark adds whether function is in opening, if function is added in this watermark is in opening, then obtains the watermark to be added template that user chooses, and according to this watermark to be added template, obtain the position to be added of watermark to be added. Afterwards, according to this position to be added, image taking window shows this watermark to be added, simultaneously in the pending image that image taking window photographs, obtain the object region being positioned at this position to be added.
If it should be noted that be not detected by user to perform watermark template selection operation, then choosing the watermark template of acquiescence. At least including the position to be added of watermark in watermark template, this position to be added can be coordinate figure. Such as when the region of this position to be added instruction is a rectangular area, the coordinate figure on these four summits, rectangular area can be stored in watermark template, just can get this position to be added according to the coordinate figure on these four summits in image taking window. This position to be added can be also the watermark edge distance value from pending image border, such as when the region of this position to be added instruction is a rectangular area, to allow this rectangular area be positioned at the lower right corner of pending image, in watermark template, then store the abscissa on this Right vertical limit, rectangular area, from the distance value of pending image right hand edge, the vertical coordinate on bottom level limit and distance value from pending image lower limb, just can get this position to be added in pending image according to the information of storage in watermark template. The particular content of this position to be added is not specifically limited by the embodiment of the present invention.
It should be noted that, the display effect of image is shot in order to not affect user, the position to be added of watermark to be added is preferably at the marginal area of image, and the such as lower right corner, the upper right corner, the lower left corner, the upper left corner etc., this is not specifically limited by disclosure embodiment. Additionally, watermark template arranges the position to be added of watermark also dependent on the whole structure of template is in the zone line of image, this is not specifically limited by disclosure embodiment.
Above-mentioned steps 201 is the process obtaining the object region in pending image, the scene adding watermark for user in the process of taking pictures illustrates, in addition, this step can also is that the scene adding watermark in user's process beyond taking pictures, such as, obtaining the object region in pending image in the image of terminal storage, the image for terminal storage adds watermark. The object region process obtaining pending image in the image of terminal storage is as follows:
When user's when checking operation of any image to storage being detected, detection watermark adds whether function is in opening, if function is added in this watermark is in opening, then obtain the watermark to be added template that user chooses, and the position to be added according to this watermark to be added template acquisition watermark to be added, afterwards, according to this position to be added, in the pending image that user checks, obtain the object region being positioned at this position to be added. It should be noted that, when the image chosen for user adds watermark, the image can chosen according to user, generate the copy of this image, copy for this image adds watermark, so when user can have the original image being not added with watermark and adds the watermarking images of watermark simultaneously. Whether watermark template is chosen for user all consistent with the explanation in the scene that above-mentioned user takes pictures with the explanation of position to be added in watermark template, do not repeat them here.
In step 202., from default font color set, obtain target font color.
In the disclosed embodiments, target font color is the font color minimum with the color similarity of object region, and this default font color set includes alternative multiple font colors. Owing to the similarity between different colours is more little, its colour contrast is more big, more easily distinguish, therefore to ensure that watermark to be added can clearly indicate out, disclosure embodiment preferably chooses the font color minimum with the color similarity of object region as target font color from default font color set.
In the disclosed embodiments, position to be added according to watermark to be added, the object region of pending image in real-time image acquisition shooting window, and from default font color set, obtain the target font color minimum with the color similarity of this object region. Wherein, this default font color set includes alternative multiple font colors, these alternative multiple font colors at least include a font color pair; Needs are met following two conditions by each font color:
Condition one: two font colors of each font color centering, centrosymmetry in designated color space. Wherein, it is intended that color space can RGB, CMY, HSV, HSI etc., this is not specifically limited by disclosure embodiment. Each color space is considered as a cube in three dimensions, and for RGB color, its instruction is that coordinate is from (0,0,0) to the area of space of (255,255,255).
Condition two: the color distance between two font colors of each font color centering is more than designated color distance. For RGB color, color distance between two font colors refers to the sum of the absolute value that two font color respective coordinates are subtracted each other, such as black coordinate is (0,0,0), white color coordinates is (255,255,255), then color distance Cd=| 0-255 |+| 0-255 |+| 0-255 |=765 between black and white. Wherein, " | | " represents absolute value sign, it is intended that color distance can be in this color space the 1/2 of maximum color distance, 1/3 etc., it is possible to in this color space very big the 1/2 of color distance, 1/3 etc., this is not specifically limited by disclosure embodiment. Wherein, this very big color distance is the point by two font color corresponding color spaces and color space central point is determined is positioned at the length of line segment within color space.
Wherein, from default font color set, the process obtaining the target font color minimum with the color similarity of this object region is as follows:
For arbitrary font color in multiple font colors that this is alternative, calculate the color distance between whole pixels in this arbitrary font color and this object region, obtain multiple color distance; By font color corresponding for color distance maximum for numerical value in multiple color distances of obtaining, it is determined that for target font color.
Wherein, the process calculating in this arbitrary font color and this object region all color distances between pixels is as follows:
Color encoded radio according to pixel each in object region and the color encoded radio of arbitrary font color, calculate the first distance between each pixel and this arbitrary font color; The first corresponding for each pixel distance is added, obtains second distance, the color distance being defined as by this second distance in this arbitrary font color and this object region between whole pixels. Wherein, color encoded radio can be respective pixel or font color coordinate figure in designated color space, it is possible to for the hexadecimal code value of this coordinate, this is not specifically limited by disclosure embodiment. When color encoded radio is hexadecimal code value, this hexadecimal code value is converted to metric coordinate figure, to facilitate follow-up color distance to calculate.
It is exemplified below how from default font color set, obtains the target font color minimum with the color similarity of this object region, for RGB color:
Hypothetical target image-region includes 3 pixels, its color coding respectively (77,77,77), (72,209,204), (71,60,139), preset font color set and include black (0,0,0) and white (255,255,255). Then calculate the first distance of each pixel in black and 3 pixels and be respectively as follows: D11=| 0-77 |+| 0-77 |+| 0-77 |=231, D12=| 0-72 |+| 0-209 |+| 0-204 |=485, D13=| 0-71 |+| 0-60 |+| 0-139 |=270, obtain three the first distances are carried out addition and obtains second distance D21=D11+D12+D13=231+485+270=986, so the distance between whole pixels is 986 in the object region of black and hypothesis. Equally, calculate white and be respectively as follows: D14=| 255-77 |+| 255-77 |+| 255-77 |=534 with the first distance of each pixel in 3 pixels, D15=| 255-72 |+| 255-209 |+| 255-204 |=280, D16=| 255-71 |+| 255-60 |+| 255-139 |=495, obtain three the first distances are carried out addition and obtains second distance D22=D14+D15+D16=534+280+495=1309, so the distance between white and the interior whole pixels of object region assumed is 1309. Owing to D22 is more than D21, so choosing white for target font color.
It should be noted that object region comprises 3 pixels only for illustrating in above-mentioned hypothesis, do not represent the number of pixels comprised in actual image area. Second distance also can be averaged by the first distance that each pixel is corresponding and be obtained, or is normalized obtains by after the first distance summation corresponding to each pixel, and this is not specifically limited by disclosure embodiment.
In step 203, the font color of watermark to be added is adjusted to this target font color.
In the disclosed embodiments, watermark to be added template includes the font color information of watermark to be added, this font color information is this font color encoded radio in designated color space, this encoded radio can be the coordinate figure in designated color space, being alternatively the hexadecimal code value that this coordinate figure is corresponding, this is not specifically limited by disclosure embodiment. After default font color set gets the target font color minimum with the color similarity of object region, the font color of watermark to be added is adjusted to target font color so that the color of the font color to be added after adjustment and object region can significantly make a distinction.
It should be noted that, from default font color set, before obtaining the target font color minimum with the color similarity of this object region, can first obtain the color distance between the font color of watermark to be added and the interior whole pixels of this object region, if this color distance is more than pre-set color distance, represent that the font color of this watermark to be added is relatively low with the color similarity of this object region, can substantially make a distinction, then the font color of this watermark to be added is not adjusted. If this color distance is not more than pre-set color distance, represent that the font color of this watermark to be added is higher with the color similarity of this object region, can not substantially make a distinction, then from default font color set, obtain the target font color minimum with the color similarity of this object region. Wherein, the numerical value of pre-set color distance is with specific algorithm different and different of the color distance between font color pixel whole in target area.
In another embodiment, if the first font color of the watermark to be added after adjusting is not liked by user, the optional font color reacquiring watermark to be added, when detecting that the reacquisition of the font color of watermark to be added is operated by user, remove other font colors outside the first font color from default font color set, obtain the target font color minimum with the color similarity of this object region.
In step 204, when detecting that image taking confirms operation, the watermark after adjusting is added into this object region, obtains watermarking images.
In the disclosed embodiments, watermark can include the content such as text, figure, when detecting that image taking confirms operation, watermark after adjusting is added into object region, carry out image by contents such as the text of watermark instruction after adjustment, figures with this object region to merge, obtain watermarking images. Wherein, in the process that image merges, the content substances such as the text of watermark instruction, figure can be shown, other positions to be added except the content such as the text, figure show after blurring display or Transparence Display or being filled with designated color, and this is not specifically limited by disclosure embodiment.
In another embodiment, when detecting that the watermark of the image of storage is added confirmation operation by user, perform step similar to the above and obtain watermarking images, do not repeat them here.
The method that disclosure embodiment provides, obtains the object region of watermark to be added in pending image; From the default font color set including alternative multiple font colors, obtain the color similarity minimum target font color with object region; Afterwards, the font color of watermark to be added is adjusted to target font color; Watermark after adjusting is added into object region, obtains watermarking images. Owing to the font color of watermark to be added can be adjusted automatically according to the color of object region, the color of watermark to be added and the color of object region can significantly be made a distinction, and therefore in this kind of watermark adding method, the resolution of watermark is high, display effect is good.
