First, as shown in FIG. 3A, the skin detecting device 1 is composed of an LED light board 11, a first polarizer 12, a lens module 14, and a circuit board 15, wherein the connector 151 and the circuit board 15 and the lens module respectively The soft boards 142 are electrically connected to each other. In addition, a light source control switch 152, a camera control switch 153, a power switch 154, a wireless transmission module 155, and a signal processing module 156 are further disposed on the first surface of the circuit board 15. It is obvious that the light source control switch 152, the camera control switch 153 and the power switch 154 are electrically connected to the circuit board 15, and when the power switch 154 is turned on by the user, the white LED bulb 111 on the LED panel 11 is turned on. And the lens module 14 is activated, so when the user covers the circular opening 21 of the LED lamp cover 20 of the skin detecting device 1 on the skin, the lens module 14 can be obtained by the light source provided by the white LED bulb 111. An image of the skin. The light source control switch 152 is connected to the UV LED bulb 112 for switching the white LED bulb 111 to the UV LED bulb 112; for example, if the user decides to see if there is any metal remaining on the surface of the skin, it can be activated.

The skin detecting device 1 completes the shooting of the skin area currently seen by the lens module 14. In addition, since the wireless transmission module 155 and the signal processing module 156 disposed on the circuit board 15 are connected to each other, when the user presses the camera control switch 153, the skin area seen by the lens module 14 is completed. The signal processing module 156 can convert the electrical signal from the lens module 14 into the original image signal of the user skin; and then further transmit the original image signal of the user skin to the wireless transmission module 155, and the wireless transmission module 155 then transmitting the original image of the user's skin to the receiving device 2; finally, the user's skin original image is processed by an application provided in the receiving device 2.

Next, please continue to refer to Figure 3A. According to the above description, in a preferred embodiment, the receiving device 2 can be a tablet computer or a smart phone, and the image sending mode can be performed by using a wireless communication method such as Bluetooth or WIFI, wherein the light source control switch 152 is The operator can switch between the white LED bulb 111 and the UV LED 112 bulb, so that during the implementation of the skin detecting device 1, the operator can use suitable detection light for the purpose of use, and the power switch 154 is used to control the skin detection. When the device 1 is activated, the camera control switch 153 controls the shooting of the lens module 14, thereby allowing the operator to capture the user's skin to obtain the original image of the user's skin.

Here, the imaging efficiency when the skin detecting device 1 is provided with the polarizing plate will be further described in the present invention. First, if the skin detecting device 1 is not provided with any polarizer, 8 The white LED bulb 111 directly illuminates the user's skin, for example, the user's face, which will generate reflected light, and the reflected light generated from the user's face is directly filtered into the lens module 14 without being filtered. If the imaging is performed, the original image of the user's skin obtained by the lens module 14 is rendered as a white background and the image resolution is not good. The imaging result is shown in FIG. 4A, and the standard deviation of the three primary colors is too small (for example, red). The Std Dev value is only 2.373, the green Std Dev value is only 2.776, and the blue Std Dev value is only 9.168), which makes the color and noise ratio distribution of the three primary colors uneven, and the gray scale value is too large, causing the brightness to be too bright. The original image of the user's skin is not well resolved, and the actual condition of the user's skin cannot be presented, and the analysis of the skin condition of the subsequent user is not easy. However, in the embodiment of the skin detecting device 1 of the present invention, the problem that the original image of the user's skin is too white and the image resolution is not good can be solved.

First, in an embodiment in which the imaging effect is exhibited by the present invention, when the second polarizer 13 is disposed on the side of the LED panel 11 near the skin, at this time, the detection light generated by the eight white LED bulbs 111 is generated. Only 4 (ie, half of the original) can be irradiated onto the skin through the through hole 132, and then, when the reflected light passes through the second polarizer 13, the main reflected light passes through the through hole 131, and is partially generated after being reflected through the skin. The scattered light can be filtered by the second polarizer 13 to remove a part of the light source, so that the intensity of the light source entering the lens module 14 is weakened, so that the resolution of the original image of the user's skin can be obtained at this time, and the imaging result is as shown in FIG. 4B. Although the standard deviation of the three primary colors has been improved (for example, the red Std Dev value is 4.830, the green Std Dev value is 7.768, and the blue Std Dev value is 12.018), the color and noise ratio distribution of the three primary colors are still uneven. And the grayscale value is still too large and causes brightness If the brightness is too bright, the resolution of the original image of the user's skin is still not good, and the actual condition of the user's skin cannot be presented, and the analysis of the skin condition of the subsequent user is not easy.

Then, in order to solve the problem that the brightness of the image is too bright due to the excessive gray scale value, and the resolution of the original image of the user's skin is not good (that is, the background of the image is still too white), the present invention further provides another preferred implementation. For example, in the skin detecting device 1, the first polarizer 12 is disposed on the side of the LED panel 11 close to the skin, so that the detection light generated by the white LED bulb 111 can pass through the plurality of periphery of the first polarizer 12. The through hole 121 is irradiated onto the skin, and then all the reflected light passes through the first polarizer 12, and the scattered light is filtered by the first polarizer 12, and then imaged by the lens module 14, and the imaging result is as follows. As shown in Fig. 4C, the standard deviation of the three primary colors approaches the median (for example, the red Std Dev value is 9.019, the green Std Dev value is 11.014, and the blue Std Dev value is 11.208), and the blue color of the three primary colors is The color distribution of green color and noise is relatively uniform, but the distribution of red color and noise ratio is still uneven. Obviously, the problem of excessive gray scale value has been improved. At this time, the skin detecting device 1 can obtain the user. Skin really The original skin image of the actual situation, and can be analyzed for subsequent skin conditions of the user. However, this image still has a white background.

Then, in order to further improve the background of the original image of the user's skin, the present invention further provides another preferred embodiment in which the first polarizer 12 and the second polarizer are disposed simultaneously in the skin detecting device 1. The arrangement position of the first polarizer 12 and the second polarizer 13 is as shown in FIG. 2B. First, the second polarizer 13 is disposed on the side of the LED panel 11 near the skin or near the LED lamp cover 19, and the first polarizer 12 is disposed between the second polarizer 13 and the LED panel 11, and Both the first polarizer 12 and the second polarizer 13 The configuration is an overlapping aspect; in the preferred embodiment, when the polarization rotation angle between the first polarizer 12 and the second polarizer 13 is configured to be 0 degrees or 180 degrees, that is, the constituent materials of the two polarizers When the molecular arrangement is in a horizontal state, at this time, the light reflected from the skin, after the main reflected light passes through the through hole 131 of the second polarizer 13, the light passes through the first polarizer 12, and the first polarizer 12 can filter the scattered light reflected by the skin, so that the scattered light entering the lens module 14 has been filtered out, and then imaged in the lens module 14, the imaging result is shown in FIG. 4D, and the standard deviation of the three primary colors is further Approaching the median (for example, the red Std Dev value is 11.184, the green Std Dev value is 12.2717, and the blue Std Dev value is 12.413), making the color distribution in the three primary colors more uniform; obviously, although Figure 4D The noise of the three primary colors is still larger. However, since the problem of excessive gray scale value has been improved, the skin detecting device 1 can obtain the original skin image conforming to the actual skin condition of the user, and can perform subsequent user skin conditions. Analysis.

According to the preceding paragraph, in a preferred embodiment, when the polarization rotation angle between the first polarizer 12 and the second polarizer 13 is configured to be 90 degrees orthogonal, that is, two polarizers When the molecular arrangement of the constituent materials is in a vertical state, at this time, the light reflected from the skin mainly reflects the light passing through the through hole 131 of the second polarizer 13, and the light passes through the first polarizer 12 again. The polarizer 12 can filter the scattered light reflected by the skin, so that the scattered light entering the lens module 14 is filtered out, and then imaged in the lens module 14, and the imaging result is shown in FIG. 4E, wherein the standard deviation of the three primary colors has been Close to the median (for example: red Std Dev value is 8.694, green Std Dev value is 9.044, blue Std Dev value is 9.008), so that the blue and green colors in the three primary colors are more evenly distributed, and the red color And the noise ratio distribution is much more uniform than that of Figure 4D; obviously, the problem of too large grayscale value has been After the improvement, at this time, the skin detecting device 1 can obtain the original image of the skin in accordance with the actual condition of the user's skin, and can perform analysis of the skin condition of the subsequent user.

According to the present invention, it can be seen that the image of the original image of the user's skin obtained by arranging the polarizer in the skin detecting device 1 can improve the gray scale value after the first polarizer 12 is disposed in the skin detecting device 1. The problem of the excessive size is such that the original image of the user's skin obtained by the skin detecting device 1 can be analyzed for the subsequent skin condition of the user, in particular, after the first polarizer 12 and the second polarizer 13 are combined, regardless of the first The rotation angle of the polarizer 12 and the second polarizer 13 is 0 degrees or 180 degrees or 90 degrees orthogonal, which enables the original skin image of the user obtained by the skin detecting device 1 to perform subsequent user skin conditions.
