Description

Portable skin measurement system and method

The present invention relates to a skin measurement system and method, and more particularly, can be measured while moving or carrying, even when not connected to a computer, while guaranteeing the same performance as when using a conventional computer, and taking an enlarged skin image. And it relates to a portable skin measurement system and method that is integrated with a sensor that can measure the skin condition and that the measurement and analysis can be immediately confirmed through a high-resolution LCD to improve user convenience.

In general, the desktop skin measurement system is composed of a computer, a skin measurement camera, a skin measurement sensor, and the like separately, and must be connected to use them, which is not only inconvenient to use, but also has a disadvantage of being portable and mobile.

Some devices have been proposed to be placed in portable small bags or to connect portable computers and measuring devices, such as laptops, in portable bags. Considering that women are women, the problem remains large and heavy.

In addition, there have been attempts to take or analyze skin photographs by connecting a skin measurement scope to a commercially available commercial PDA.However, the PDA and the skin measurement system have poor interconnection and additional inconveniences of connecting or carrying additional devices. There was a problem that can not be used for a long time because the capacity of the power battery is not large.

In addition, the portable wireless skin measurement and display device proposed in Registered Utility Model No. 0255325 has a high portability, and is connected to a TV when a customer visits to view a photograph of the skin taken on a TV screen or analyze the measured skin condition. Although it can be seen on TV, it is expected to be inconvenient to use in places where TV is not prepared.

In addition to the structural inconvenience of the skin measurement system as described above, the components of most skin measurement systems are separated from the scope and sensor, so that the number of products to be prepared for use increases, or the cost of preparing or managing the product increases. There was a ham.

Specifically, FIGS. 1 to 3 illustrate skin measurement systems used to date, which are inconvenient for portable use due to size or components.

First, FIG. 1 is an inconvenience that can be used only in a place where a skin measurement system, for example, a scope 101 or a skin sensor 102 is connected to a desktop computer 100 and configured to perform skin measurement and analysis. There is this.

Next, FIG. 2 illustrates that the desktop skin measurement system of FIG. 1 is carried by connecting a small computer 200 using a laptop or an equivalent LCD monitor with a skin measurement system such as the scope 201 or the skin sensor 202. As an example of the use of the bag 203 in a portable manner, it is still inconvenient for the injectable women to use the skin measurement system every time they use the skin measurement system, and then have to connect to a computer and consult a customer.

3 illustrates an example in which a skin measurement system, for example, a scope 301 is connected to a PDA 300 commercially available as a method for improving portability in the example of FIG. 1 or FIG. This is not enough to run the skin measurement system for a long time and the external interface of the PDA is difficult to connect all the skin measurement system consisting of a scope or sensor.

From this, the present invention is to solve the above problems, while providing a special service to the customer through the skin measurement or through this while visiting within the sales representative or related sales store that wants to sell skin improvement products or cosmetics to the customer It is an object of the present invention to provide a portable skin measurement system that is convenient for carrying and use by counselors who want to provide skin measurement services.

It consists of a high-resolution LCD display device, and a high-performance microcomputer that analyzes the skin condition of the subject using the photographed skin photographs and measured sensor values, and displays the results. A portable skin measurement system is provided.

In particular, the present invention is configured to be detachable by exchanging with different sensor modules according to the purpose of use, and the sensor module independently calculates the sensor measurement value, the main control device with digital data processed in the required form Characterized in that configured to be delivered to.

According to the portable skin measurement system of the present invention having the above configuration, since the main user is a female, the product should be easy to use and have good portability, thereby reducing the complicated user interface and making it light and easy to carry.

In other words, the skin measurement system for diagnosing the skin of most customers is divided into a scope part for enlarging the skin and a sensor part for measuring the skin condition, which is used as a separate product. It is easy to use by integrating the scope and sensor into the main body, and in particular, the scope and sensor are integrated so that customers can easily consult the skin measurement by simply carrying a single device. Replace the appropriate removable sensor module so that it can be used.

Therefore, it is possible to visit the customer in person and provide customer service, thereby reducing the inconvenience of having to come to the store for skin measurement, and the customer counselor can provide a higher level of service to the customer. It will be a great help to improve the image of the company to which the counselor belongs.

In particular, by using a standardized sensor module that can be separated or exchanged, it is possible to equip and use a sensor suitable for the purpose of use, thus greatly reducing the cost of preparing various sensors.In addition to the main CPU of the main body, By using the microcomputer, the measured analog sensor value is processed into digital data for the purpose and transmitted to the main control part through the communication interface to reduce the distortion or loss that may occur in the process of transmitting the signal. There is an effect that can improve the measurement accuracy necessary for analysis.
