Fig. 3 illustrates the process flow diagram that the utility model is judged a kind of embodiment of color lightness attribute and changes in temperature attribute.

Embodiment

In the utility model, with " color four seasons theory " basis as judgement colour of skin attribute.As shown in Figure 1, spring, the type colour of skin was meant colour of skin high brightness, warm-toned; Summer, the type colour of skin was meant high brightness but the colour of skin of genus cool tone; The autumn type colour of skin is meant the low lightness and the warm-toned colour of skin; Winter, the type colour of skin was meant the colour of skin of low lightness and cool tone.

In an embodiment of the present utility model, the tester at first is close to the image acquisition areas of camera testee's facial skin photographs, to obtain testee's skin of face image.The image acquisition areas of camera preferably has the flange that slightly protrudes in and surround cam lens, like this, can get rid of the interference of background light when image acquisition areas is close to face, obtains face-image color and briliancy accurately.Because image acquisition areas is close to face, make camera lens constant to the distance of face, the variation that this has equally also been avoided the face-image briliancy that causes owing to variable in distance makes facial image acquisition more accurate.

The skin of face image of being taken by camera is stored and flows to the rgb value sampler.Obtain the rgb value of skin image according to ad hoc rules by the rgb value sampler.In a preferred embodiment of the present utility model, the central pixel point from captured skin image obtains corresponding rgb value simply.

Because the characteristic of people's face skin, in the utility model, sample by a large amount of, find in the rgb value of skin image, represent the R value of red (Red) all significant high with respect to green (Green) value (G value) and blue (Blue) value (B value) usually, and difference between the difference between the different skin R value and the different skin G value or the difference between the B value are compared, and just seeming is not so obvious.Therefore, in embodiment of the present utility model, the R value is ignored.

In the utility model, utilize the G value of skin image to judge the lightness height of the colour of skin.In an embodiment of the present utility model, to the division of the lightness attribute of color, the example of the lightness that promptly concrete G value is corresponding is as follows: the G value is from 155-161,148-154,141-147,134-140,127-133,120-126,113-119 are high to middle high brightness to 106-112; The G value is from 99-105,92-98, and 85-91,78-84,71-77,64-70,57-63 is a low lightness in being low to moderate to 50-56.When G value during, think that the colour of skin is a high brightness greater than certain threshold value; Otherwise, think that the colour of skin is to hang down lightness.Of the present utility model one preferred embodiment in, when G value (G＞105) greater than 105 the time, think that the colour of skin is a high brightness; When the G value is less than or equal to 105 (G≤105), think that the colour of skin is to hang down lightness.

After lightness is judged, carry out the changes in temperature of the colour of skin and judge, for example, when the B value is thought cool tone during greater than certain threshold value, otherwise then think warm tones.According to of the present utility model one preferred embodiment, if the B value is no more than 50% of G value, that is: B＜G * 50% then is a warm tones; If the B value surpasses 50% of G value, that is: B 〉=G * 50% then is a cool tone.

In another kind of embodiment of the present utility model, to the judgement of colour of skin changes in temperature attribute can be not yet by relatively the drawing of B value and G value, but by the color of testee's eyeball is judged simply.For example, the color of testee's eyeball is black partially, then belongs to cool tone; If the color of testee's eyeball is brown partially, then belong to warm tones.

Certainly, the order of the judgement of the judgement of lightness attribute and changes in temperature degree is not certain.Equally also can carry out the interpretation of changes in temperature degree earlier, after carry out lightness and judge.Combination according to lightness and changes in temperature degree at last divides four seasons attribute to the colour of skin.

Draw after the lightness and changes in temperature attribute of the colour of skin,, just can judge the four seasons attribute of the colour of skin according to above-mentioned description to Fig. 1.

Marked the different pairing suitable colors of color four seasons attribute on the PCCS tone illustration, after judging the four seasons attribute of the colour of skin, just can in the PCCS tone illustration, choose the color that is fit to the different attribute colour of skin according to " color four seasons theory ".

The judgement of above-mentioned colour of skin attribute is carried out in the color attribute judgment means of the utility model system.

Pairing the sheet sample of color that will be fit to testee's colour of skin subsequently exported to output unit, selects final hair color for the testee according to hobby.Choose the color of hair dyeing as the testee after, system can print the hair dyeing prescription and the operating process of standard according to the hair dyeing product that is write down in the database, is contrasting for the colorist and is operating.

Because the test result of carrying out according to method of the present utility model has stable and repeatable, these test results can be stored in other data of client in the customer data storehouse together, in order to using next time.

In addition, recommending and selecting in the process of hair dyeing color development, except according to the above-mentioned color attribute determination methods, system of the present utility model also allows the tester to carry out the analysis of more refinement with reference to further feature of testee's face (is that flat type or solid type, bone are given prominence to or soft as face) and the initial color development of testee.

The utility model realizes that the system of said method step can be independent instrument, also can be module or the platform that is implanted in the computing machine.The system principle block scheme of an embodiment of system of the present utility model as shown in Figure 2.System of the present utility model comprises camera, processing unit, input block, output unit and storage unit.Wherein, processing unit comprises rgb value sampler and color attribute judgment means.Camera links to each other with storage unit by incoming line, and the image of taking is flowed to storage unit; The rgb value sampler is read skin image from storage unit, and skin image is carried out the rgb value sampling, gives the color attribute judgment means with the rgb value of gained then.Color attribute judgment means and storage unit are carried out two-way communication, judged result can be flowed to storage unit on the one hand stores, on the other hand, if desired, the color attribute judgment means can also be obtained out of Memory (for example other is flowed to the information of storage unit by input block) and carries out auxiliary judgment from storage unit.The judged result of color attribute judgment means is finally exported to output unit and is shown.Customer information in the storage unit also can flow to output unit by outlet line.
