Description

A kind of method that realizes skin colour change of instant communication tool

Technical field

The invention belongs to the technical field of image processing of computing machine, relate in particular to a kind of method that realizes skin colour change of instant communication tool.

Background technology

Current, along with network universal day by day in people's daily life, immediate communication tool is just more and more used.In order to satisfy people's use needs, with QQ the immediate communication tool of representative, enriching constantly and improving self every function, to adapt to market and user's needs.The QQ dermatodyschroia is exactly a kind of in above-mentioned perfect every function.

With QQ is example, and in present QQ client, skin is made up of a series of picture and background fill color.Picture file by reading configuration file with and corresponding pinup picture coordinate and pinup picture mode, realize the drafting of whole QQ client skin.Although this skin making and drafting mode can make things convenient for the making of QQ skin greatly, for the user, also can only from the skin of having produced, select oneself like a kind of, and can not realize customization function skin color.Consider the market that may be unfavorable for opening up QQ like this, therefore, current the trial increases the colour change function of realizing QQ skin in the QQ client.When realizing this colour change function, need consider following situation:

At first, can not make amendment to the QQ skin that has released now, the QQ skin that guarantee legacy version can be realized the function of variable color under new QQ client, can guarantee that so former user can experience new function; Secondly, skin can not destroy the rapport of original skin color after finishing variable color, new change color can not change the texture and the relationship between light and dark of panel, will be consistent with original panel on style, will keep some pictures simultaneously can not make amendment to it, such as the image of QQ penguin; Once more, need provide a kind of self-defining color mode to the user, the user is by obtaining self-defining color by dragging stroke bar or input parameter in Color Chooser Dialog, and with this color is the realization of goal dermatodyschroia, when carrying out change color, also need to realize the variation of the whole light and shade of panel simultaneously.At last, not only can effectively also want the main panel of QQ client can be effective to the chat conversations window that the user uses always for this color-change technology.

For realizing the function of above-mentioned QQ dermatodyschroia, in the prior art, have 2 kinds of methods that realize the image variable color to be worthy of consideration:

Method 1:

In the method, at first, by preset threshold select some in the colour solid model with the reference color distances color within threshold value, then, the color in this threshold range is operated, this method is to operate at a certain part of image;

The shortcoming of this method is: though face can be handled the details of image well in realization, thereby can choose by accurately that local color is very close pel, but, exactly because also this point, this method can't be selected the similar pel of overall color, if threshold value is provided with improper, is easy to cause color not have the complete or wrong problem of color choosing of choosing, and revises difficulty; In addition, because this method employing is the RGB color mode, any color is all by three color components decisions, therefore, for the user, bigger difference may appear in three color components of two close colors, thereby can occur bigger problem in the selection of similar color;

Method 2:

This method is considered from integral image, adjusts the proportion of each component of RGB in the image, thereby reaches the purpose of change color;

The shortcoming of this method is: because this method is one image carried out the method that integral color is adjusted, therefore, it can't be with the needs adjustment and the chromatic zones that does not need to adjust separate; In addition, for different colors, adopt this method, adjust the final effect that same color component shown with same degree and difference can occur, thus, this method may be destroyed the color balance of image itself.

More than 2 kinds of methods though the function of image variable color is provided, but, these 2 kinds of methods are all carried out color adjustment at RGB, because the user is a notion by color to the perception of color, and this is to represent that at the RGB of computing machine pattern is different with image, therefore, based on this reason and aforesaid other shortcoming, when these 2 kinds of methods of the prior art are applied in the variable color of QQ skin, can not well meet the demands, so and inapplicable.

In the present invention, when realizing the dermatodyschroia function of client, mainly consider following key problem in technology point:

(1) need to adopt suitable color to judge and choose mode: because the user is a notion by color to the perception of color, and this is to represent that at the RGB of computing machine pattern is different with image, therefore, the selection and the conversion of color are carried out in this perception that needs a kind of color showing pattern of selection to come analog subscriber then according to this color mode;

(2) needs are selected suitable color method for transformation: consistent with original skin style in order to make change in color, needs keep some color characteristics of original skin, as the light and shade transition of skin, the colour purity of skin;

(3) because every kind of skin all has a fixing tone, for the picture of not formulating Standard Colors, need to adopt the method for statistics to find between the chromatic zones that needs to change, and for the uniform picture of those each color distribution, then need to quote between the chromatic zones of other picture and judged.

At above-mentioned key problem in technology point, the present invention proposes following solution:

Adopt the HIS image model, the HIS pattern is a kind of a kind of color mode that is similar to the human eye apperceive characteristic.It adopts color (H), brightness (I), three color components of saturation degree (S) to represent color, adopt this color mode can better tell the part that to carry out change color, and it is easy to adjust, wherein human eye mainly is a H component by wherein to the perception of color, and different H values are corresponding to different colors.Referring to Fig. 1, realize that to the present invention is based on this HIS image model the specific implementation step of skin colour change of instant communication tool is described in detail:

Step 101:

Import user-selected color parameter into by main panel and/or instant messaging window;

Step 102:

Judge the type of the color parameter that imports into: if this color parameter is the parameter of RGB pattern, then execution in step 103; If this color parameter is the parameter of HIS pattern, then execution in step 104; If this color parameter carries out the recovery mode parameter of color restoration for indication, then execution in step 112, and the view data pointer is made as the pixel space of original image, and then execution in step 111, according to view data pointer pixel space replot picture pointed;

Step 103: with the Parameters Transformation of RGB pattern is the parameter of HIS pattern, and execution in step 104 then;

Step 104: judge the type carry out the picture that color more is somebody's turn to do, if this picture is 256 images, then execution in step 105 and subsequent step thereof, if this picture is 24 bit image, then execution in step 108 and subsequent step thereof;

Step 105～step 107: owing to judge that in step 104 obtaining picture/mb-type is 256 images, therefore, in step 105, set up a new color data space corresponding to palette, and this color data space carried out initialization, then, in step 106, call the color conversion module, based on the HIS color mode color data is made amendment, and the color data that will be converted into the RGB pattern after will revising is kept in the new color data space according to the color parameter that imports into, at last, in step 107, the view data pointer is pointed to new color data space, execution in step 111 again;

Step 108～step 110: owing to judge that in step 104 obtaining picture/mb-type is 24 bit image, therefore, in step 108, set up one and new carry out initialization corresponding to the pixel space of bitmap and to it, then, in step 109, call the color conversion module, color data is made amendment based on the HIS color mode according to the color parameter that imports into, and the color data that will be converted into the RGB pattern after will revising is kept in the new pixel space, and is last, in step 110, the view data pointer is pointed to new pixel space, and execution in step 111 again;
