Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that creates a unique shape that mimics the skin surface O and outputs pattern information that serves as an index for classifying and determining skin properties and skin types.

This calming device can be used for skin, ili'7) heavy speed, 8 handicap 1, amphibious, and even large d.

On the skin surface, there are fine undulating patterns (skin patterns) consisting of many thin grooves called skin grooves, almost rectangular mounds called skin mounds formed in the skin grooves, and pores. The metabolism of the skin reflects its physiological functions. 75i was used to examine the fine shape of the skin surface.
Accurately identifying the skin is the key to obtaining an index for knowing the skin's 1i'7) properties and skin, which are essential for treatment, diagnosis, etc.

In the past, many efforts have been made to improve the extraction of special forces by turning the surface of the skin. However, the quality of the skin is determined by the size and number of pores, the thickness, depth, direction, and density of the skin.
Note: By interpreting and synthesizing the so-called skin pattern characteristics such as the size and shape of the skin mounds, we are now examining the microscopic shapes of the oral skin surface in a stationary manner, which has generally been done principally and k-primarily. What I do is because I'm tired of rice, and I'm tired of it.

Then, the obtained fc amplitude is processed by a conveter and calculated as a Shipo 1 Direct Information Book (``Nihonfu Cosmetics Technology Ministry Biographies'', Vol. 13, No. 2, pp. 44-49).

Ori is a method of calculating the surface @ foot of the area that falls within a predetermined brightness/darkness range for each of multiple areas obtained by changing the illumination conditions of the photographic light source. Osugi: There is a method of extracting the special number H by analyzing and processing it using a complex pattern processing program using a high-speed computer. However, such a method is not able to hold the wick because it is based on subjective experience, and it is dangerous to use a method that requires specialized knowledge to operate. Peace of mind 9
The present invention, which is not practical due to its small size, is small in size, low in saliva, easy to operate, and has a special effect on the shape of the skin surface that closely matches the subjective and subjective appearance of the toilet.・The purpose is to provide a classification device.

The special feature of the present invention is to process the reverse surface □□□O pattern information, express it at the level of a finite number of plates, and from these levels, find the excessive special number 00 cloth such as its continuity. According to the 70 classifications of these distribution patterns, the shape of the skin surface can be specifically determined.As parameters for these distributions, standard deviation, number of pixels above a certain level, etc. can be used. By increasing the data O difference between each direction for the data variation pattern as a parameter, the special number extraction O refinement can be further improved.

Next, the disaster relief of the present invention will be explained.

Figure 1 shows the % detection and classification system of skin surface shape according to the present invention! ■-Real gallery 1" is shown in a block diagram. Also in Figure 1, 1 indicates the skin J11 that should be used sparingly! or its replica. In 2X and 2Y, there are 2 lights. As for the equipment, it would be better if there were three lights shifted by 120 points from each other, and it would be possible to avoid excessive lighting.In addition, for the purpose of keeping the equipment in the dark, a ridge light source is used. By combining optical fibers and reflectors, it becomes convenient to adjust the amount of light, the angle of incidence of light, and to mount the light source itself.

Since these are not the main matters of the present invention, further description of O will be omitted.

3 is a magnifying optical system that uses a low @ rate microscope or a close-up lens to obtain a number with a predetermined magnification (approximately 1.0 to 2.0). 4 is a scanning/converting device that scans the optical unit and generates a signal whose amplitude changes according to the strength of the light. It is possible to use a photographing unit.In this implementation report, we will discuss the use of light and shade information.It is possible to add color information and extract more diverse skin percentage changes. , Comparison of the amplitude values, continuity, etc. of the three primary color components is particularly important, but I will not discuss it because it departs from the main point of the present invention.It is a prefix word in 5Fi, and it is used to compare the output level of the O output level of the 5Fi conversion device.

In most cases, the A/D converter can be replaced with a ridge threshold circuit. In this case, the -fIIL can be changed manually or by a signal from the information processing device 10 and can be set aside.

In the 6DA/DR converter, the sampling device pond A
The output of the A/D converter (6), which is included with the /D converter, may be stored in the frame memory (7) and used for primary recording of data. However, the frame memory 7 can be omitted. 08 is the A/D odd smell 6 or the frame memory 7, the information processing device 10, and the interface device, and depending on the case, the information processing device [10 It may also include a monochrome ff1f & monitor 9 interface device for monitoring the inlet iJ CD signal.

Improves working memory and control functions.

The main memory is used to store A/D converted signals. The arithmetic and logical operation functions selectively and systematically perform the arithmetic and logical operations necessary for data processing using the control function. The working memory function temporarily stores intermediate and final results of calculations. The control function is suitably of the so-called program side leg type, and in order to control the above-mentioned functions, safe functions are activated at required times.

A small combiator called a personal computer can be used as the post-processing device that provides these functions. In arithmetic and logical operations related to the main features of the present invention, at least Comparison of magnitude between constants, parameter indicating the dispersion of the Calidata distribution For example, 0 and 11 require a function that can be fulfilled by standard polarized stars, and to store information such as the number of tails required for calculations, etc. 012, which is an external memory provided in the computer, is a color or monochrome CRT display device, and 13 is a printer.

Next, the operating principle will be explained. Here, we will discuss the case where the A/D conversion is 2-channel, that is, the case where it can be performed with a simple 1-threshold series circuit, but from this, we can also infer the operating principles for more complex cases by analogy to each part.◎First of all, The skin or skin replica 1 is illuminated by the light sources 2X, 2Y. The squad of skin or skin replica 1 is enlarged by the enlarged original school thread 3. The scanning/converting device 4 scans this @ and generates a tortoise signal whose amplitude changes depending on the intensity of light at each part. This ring name has passed through preamplification story 5, and as mentioned earlier, A

The information processing device 1 (1) is provided through the interface device 8, and is guided to the information processing device 1 (1).
In contrast, the output from the interface device 80 is added, making it possible to monitor the 2F direct area O-reli as shown in FIG. The 21st train data led to the information processing device 10 is the main memo in the ↑H information processing device 10! Due to the J-i function, the signal δ is stored as a signal corresponding to the above-mentioned 91 〃 or Ill □ “ along with the IXL device information on the two orthogonal image plane.

Next, data processing! 7) 1 [Explain MJ.

Information Processing Device - With the control function and main memory function, the stored data can be stored in four different areas, each having 45 quiet areas, as shown in Figure 3b, compared to the original two-story house. A readout corresponding to directional water phototaxis is performed.

This can be replaced with 2 units of data obtained by rotating replica 1 by 45 rotations. The data string from these tanigata domo eclipses is
1" and ゝ0〃's old name Yu 1", and after this, ゝ 1 //■ Calculate the length using the arithmetic and calculation function, and apply it to each of the valley running eclipses. , %IJF's length and the frequency with which that length appears are stored in one function of the working memory.

These memories are read out, and the average of each continuous length in the running direction, the standard deviation of the frequency with respect to the continuous length, the total number of % 1//O, etc. are calculated. These results are stored in the working memory field Km. Furthermore, the continuous lengths in each direction are averaged and recorded in the working memory field.

The 911′ continuous length in each of the four scanning directions corresponding to the skin or 70 replicas obtained in this way is
The standard deviation, the total number of N1, etc. can be used as an index showing the special characteristics of the skin as follows. Needless to say, he is talented.

(1) Blood (Sl) that has been scanned and leveled in four directions over a continuous length can be used for CO discrimination and division, even if the pore size is relatively large or not so large. ) In the radial direction of the four scan directions, among the continuous length average values O, pair the orthogonal scans and calculate the respective M average scan ratios, and calculate the larger absolute value of the two ratios. (Direct (S2) is: Skin pattern■ Directionality, that is, those whose skin grooves are relatively radioactive, those where the skin grooves flow in one direction■Identification/classification, (4) Full surface of @ is divided into meshes (for example, divided into 256 meshes, each mesh is formed by 13x13 dots), the number of each mesh ID'1' is calculated, and the coefficient of variation is calculated. It can be used for the initial classification and classification of things that are small, have large ridges, or have irregular ridges.

The above-mentioned θ discrimination classification will be explained in more detail in column (S2). Figure 3a shows a second formation with a uniformly flowing anti-crow pattern, which is different from Figure 2. This 21 direct image 01

It varies depending on the direction.

From these data strings, the number of -1 late blooms and their frequency are shown graphically as shown in Figure 3C.

In this diagram, ■, ■, ■, and ■ are in the O running direction in Figure 3b.■
, ■, ■, and ■, and the curves showing the distribution of each roundaboutness are gradual. It will be easily understood that the length of the dot part is short in most cases, and the C+ frequency is as shown in Figure 3C.The distribution in the direction of ■, which is orthogonal to the direction of ■, is also It can also be understood that the results are as shown in Figure 3C υ.In this way, the dry mean ratio of the number of consecutive members of distribution ■ and distribution ■ in Figure 3C will deviate from 1.〇 distribution ■ and 5 + cloth ■ Hahanu They have similar curves, and the linearity ratio of each luck @major number θ is almost 1, but the two sets of orthogonal running whiskers θ lagging major number memouniformity are close to 1 here. Then I won't use it.

Considering this in the case of the skin in which black areas are evenly distributed radially in Figure 2, the average value υ ratio of luck due to the set meal that is prepared with shellfish is close to 1. I can say that. Therefore, the persimmon-betsu portion mentioned in (2) becomes the i-th town.

The discrimination classifications (1), (3), and (4) are easy to infer, so detailed explanations are omitted.On the side of detecting the waiting ridges of the mouth skin surface shape, the above-mentioned S4, S2, S6, S, etc. Divided into 51-1, 51-2, 51-6"°°, 52-1

You can force it.

The results obtained as described above can be expressed as numerical data and patterns on a memory machine, working memory function, control axle, etc.
If it is appropriate to output and display the results on the printer 13, the results can be stored in the external memory 11, and new and old data can be compared.

If a small combiator is used as the information processing device 10, there is no difficulty in manufacturing special hardware, and the combiator's versatile data processing capabilities can be used to perform complex analysis and identification. Town llI [tonashi, 1t110 measurement g
It is also possible to use manual labor from Sae, interview data, festival data, etc., and output the diagnosis from the general meeting. When using a small-sized computer, it is effective to add a buffer + stage to make the word length equal to the number of bits of the meconium of the A/D conversion and NO small-output processing computer.

As mentioned above, the present invention is easy to use because anyone can obtain various basic indicators in a short time. ○ It can be placed in stores such as hospitals, pharmacies, chemical stores, etc. for easy circulation.
