Description

Detection method and detection device for controlling the degree of color change

The invention relates to a detection method and a detection device, and more particularly to a detection method and a detection device for controlling the degree of color change.

In the dressing of a person, although the hairstyle itself is very important, "hair color" is an important key to personal style. Choosing the right hair color can not only change the overall impression, but also make the facial features more three-dimensional and more style. Bright.

The color expressed by the hair depends on the pigment factor. The hair contains pigment particles composed of protein in the sebum layer of the hair follicle, which is the melanin pigment of the hair. The hair contains four kinds of melanin pigment particles: black and brown. Red, yellow and so on. Oriental hair color is generally black, black is due to the proportion of black and brown melanin pigment particles in oriental hair, and the proportion of black melanin pigment particles is generally higher than brown melanin pigment. particle. Therefore, in order to have beautiful and moving hair, the change in hair color becomes an indispensable element.

In the change of hair color, whether the original hair color can be successfully changed to the target hair color depends on the original hair color, hair quality and other factors, among which the original hair color is the main factor, when the original hair color has passed In the case of black, it is difficult to color other colors on the original hair color without first performing the bleaching of the original hair color. This bleaching procedure is usually accomplished by passing a catalyst with a bleaching powder, which is typically used to make the bleaching powder catalyzed to function to fade the hair color, and the concentration of the catalyst used is applied to the hair. Time is about the degree of color change; on the other hand, the process of dyeing after the hair is bleached, but with or without the bleaching process, the process of dyeing also requires the matching of the catalyst, so that the dye is Catalyst to function to color the hair color.

In the process of germination, after the hair starts to bleach (catalyst and bleaching powder), the effect of withdrawing melanin begins to occur, and the color of the hair begins to fade. Therefore, the hairdresser must look at the original hair of the client. In addition to the color of the corresponding catalyst (eg 3%, 6%, 9% or 12% dioxygen), the time of application must also be determined.

The conventional procedure of dyeing hair after germination is first explained. First, the hairdressing designer must color according to the expected final target selected by the client, depending on the current color condition and hair quality of the customer, whether to first float. Hair (when the final target hair color is very different from the current hair color of the customer, it usually needs to go through the tranching process). If you want to carry out the hair styling, you need to confirm the target hair coloring (easy to reach the final goal in subsequent coloring). Hair color), according to the current color status and hair quality of the customer to determine the type of catalyst to be applied, the hairdressing technology in the use of the catalyst is a comparison table to let the hairdresser know that the corresponding catalyst is The application time on the hair (for example, 12% of the oxygen emulsion is applied to the case where the original hair color is quite deep, and the application time is 40 minutes), and therefore, the hairdressing designer of the prior art performs the hair styling according to such a common specification. After the germination is completed, the hair dyeing process is performed, and the hair dyeing procedure is also like a tranching procedure. The hairdressing designer knows the time when the catalyst should stay on the hair.

The lack of the prior art is that the catalytic strength of the catalyst is affected by the humidity and temperature of the environment. The comparison table used by the prior art is only a reference. When the environmental conditions change, the catalytic effect of the catalyst is often Mutations are made, which in turn causes the target to fade in color or the final target color is different from what was originally expected. In addition, the existing comparison table does not fully correspond to the customer's hair color. Hairdressing designers often have to make decisions through experience judgment. Therefore, the situation of misjudgment often occurs frequently, and the color development is different from the expected color development. Excessive hair will also cause a burden or damage to the customer's hair or body.

2 is a flow chart of a method for detecting a change degree of color change according to an embodiment of the present invention. The method includes: setting step S100, original color detection step S200, color change time estimation step S300, color change time detection step S400, time correction step S500, and remaining time output step S600. By these steps, the operator is made aware of the correct remaining time for bleaching or dyeing.

In the setting step S100, the operator sets a target color data and a type of the catalyst according to requirements. For example, the target chrominance data is, for example, a light chestnut color (the target chrominance data can also be obtained by detecting the sample of the target chrominance by the color sensator), and the type of the catalyst is determined, for example, by using a concentration of 9 % of oxygenated milk. The catalyst is a double oxy-moisture. For example, the common type selection of the bis-oxygen emulsion includes options of concentrations of 3%, 6%, 9%, and 12%, and the present invention can be pre-built by conventional catalysts. The correlation color change regression line is placed, which allows the operator to select a variety of catalysts.

The original color detection step S200 obtains the original color data of the hair of the user to be color-changed by a color sensing module (including a color sensor).

The color change time estimation step S300 is based on a color change regression line to obtain a first estimated time for the target color to be obtained under the original color data. In this step, the color change regression line is generated according to the target chrominance data and the complex reference original chrominance data corresponding to the type of the catalyst and the reference change time thereof, that is, through the step Confirm the time (flush or dye) of the user's hair color.

The color change time detecting step S400 is performed by the color sensing module to obtain a detected color data of the current hair color of the hair when the catalyst is applied to the hair for a predetermined change time. The preset change time is shorter than the first estimated time.

The time correction step S500 estimates a color change speed of the preset change time according to the preset change time and the difference degree between the detected color data and the target color data, and according to the target color The degree of residual difference in the data and the rate of change of the color change estimate a second estimated time. In this step, since the value of the three primary colors of the detected color data and the target color data must have a gap, the gap has a value of the preset change time (for example, 5 minutes), according to which That is, the time required to reach the three primary color data of the target color data can be estimated, which is the second estimated time, that is, corrected by detecting the actual drifting or dyeing speed to estimate that it is consistent with the current The remaining time of bleaching or dyeing in the environment allows the operator (such as a hairdresser) to accurately control the degree of change in hair color.

The remaining time output step S600 outputs the second estimated time to indicate the time required for the remaining hair color change for the aforementioned operator (such as a hairdressing designer) to know. Further, the remaining time output step S600 further includes generating a reminder signal at the end of the time required for the remaining color change. The reminder signal allows the corresponding device to sound and/or illuminate to alert the operator.

Next, please refer to FIG. 3, which is a flowchart of a method for detecting a change degree of color change in another embodiment of the present invention. In order to make the detection result of the color sensing module correct, the method further includes a white balance correction step (first white) before the original color detection step S200 and the color change time detecting step S400. The balance correction step S101 and the second white balance correction step S301) are used to correct a color sensor of the color sensing module for detecting the original color data and detecting the detected color data.

4 and FIG. 5, FIG. 4 is a functional block diagram of a detecting device for controlling the degree of color change in an embodiment of the present invention, and FIG. 5 is a schematic diagram of a detecting device according to an embodiment of the present invention. . The detection device 100 includes a color sensing module 110, a control module 120, and a response module 130.

The color sensing module 110 is configured to detect hair to obtain color data of the user's hair. The color sensing module can include a color sensor and a light emitting unit, the light emitting unit emits light to the user's hair, and detects the hair color of the user's hair by reflecting light to the color sensor. .

The control module 120 is coupled to the color sensing module 110. The control module 120 stores a plurality of target color data and a plurality of types of catalysts, and stores a plurality of color change regression lines in the target color data and corresponding catalyst types, and operates to set a target color data. And the type of catalyst. And the operator controls the color sensing module 110 to obtain the original color data of the user's hair, and the operator can operate the control module 120 to generate the target according to the color change regression line to which the target color data belongs. A first estimated time of hair coloring, and operation to initiate time calculations when the catalyst is applied to the hair (e.g., through a button, intuitively and quickly for the hairdresser to manipulate). The control module 120 can control the color sensing module 110 to obtain a current color detection data of the hair after a predetermined change time, or the control module 120 generates a reminder signal after a time. When the operator controls the color sensing module 110 to obtain a current color detection data of the hair, the preset change time is determined (that is, the preset change time of the example is determined by the actual operation process of the operator. Decide).

The control module 120 further estimates a color change speed of the preset change time according to the preset change time and the difference between the detected color data and the target color data, and according to the target The degree of residual difference of the chrominance data and the speed of change of the chrominance produce a second estimated time and the second estimated time begins to count down.

The color data generated by the module 110 can be adjusted to the offset level according to the white balance correction result, and the color data is corrected to the correct value.

It is worth mentioning that the appearance of human hair color is mainly caused by the combination of two different pigment forms: eumelanin and pheomelanin. The configuration of these two kinds of pigments will vary from person to person, and thus cause different hair color of different races, such as: black hair, brown hair, blond hair, red hair color, etc. Therefore, in order to make the control of the color change degree of the present invention more precise, in the foregoing setting step S100 and the control module 120, the selection of the color development configuration may be further included when the target color data is set. The hair color configuration is set in the race. For example, when the customer is Asian or African, the sub-African race can be selected, and the data of the subsequent senses or stored data are based on the data of the race; and when the client is a European or American When planting, you can set the corresponding race according to its original natural hair color.

More specifically, the setting of the ethnicity is for the color sensing mechanism to determine the ratio of the RGB three primary colors obtained by the color sensation, and further to obtain the added value of the scaled RGB values. For example, the customer's original natural hair color belongs to the black color of the Asian race (because the distribution of the three primary colors is even, the ratio can be set to 33%, 33%, 33%), assuming that it is sensitive. At present, the RGB three primary color values (between 0 and 255) of the hair color are R: 40, G: 37, and B: 33, respectively, and the superimposed result of the final output is 40*33.3%+37*33.3%+33. * 33.3% of the total value, by which the ratio of the various primary colors of the present invention is calculated. For another example, when the customer is a golden-colored North American race, the ratio of the RGB three primary colors can be set to R: 48%, G: 42%, B: 10%; when the customer is reddish When the European color of the hair color is used, the ratio of the RGB three primary colors can be set to R: 70%, G: 15%, and B: 15%. The usage ratio can be determined according to the RGB three primary colors of the original natural color of the race. As far as the above-mentioned access ratio is not used, the detection and adjustment can still be performed by summing the direct RGB three primary color values.
