Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a skin observation device suitable for observing irregularities on the skin surface, particularly minute irregularities.

<Prior Art> In over-the-counter sales of cosmetics, it is important for beauty consultants to select and recommend cosmetics that are most suitable for each customer based on their own understanding.

Conventionally, as a means of selecting and recommending such cosmetics,
A method of measuring and displaying facial moisture, a method of taking a close-up picture of the skin with an ITV camera, and a method of observing the skin on a TV monitor have been adopted.

However, the former method is inaccurate because it diagnoses only moisture among the many parameters that determine the condition of the skin, such as oil, water, wrinkles, etc., and is insufficient to gain sufficient customer satisfaction. That's enough. tfC, the latter requires the ITV camera to be placed close to the customer's face, and the lighting is extensive, making the customer nervous and sweating due to the heat of the lighting.
This has the disadvantage of not allowing observation in its natural state and causing discomfort to the customer.In addition, it is not possible to focus on uneven parts of the face such as the nose, and it is especially difficult to observe cosmetics. b't - It is impossible to capture the minute irregularities of the skin, which are important factors influencing the condition.

<Object of the Invention> In order to eliminate the above-mentioned drawbacks of conventional skin observation methods, the present invention aims to provide a skin observation device that can sufficiently observe skin irregularities, especially minute skin undulations. do,.

<Structure of the Invention> In the present invention, the tip has an image guide↓ and a light guide°.
an image fiberscope consisting of an ITV camera connected to this image fiberscope, and an ITV camera connected to this image fiberscope;
It consists of a TV monitor connected to a TV camera and a light source that supplies light to the image fiberscope, and the angle formed between the optical axis of the image guide and the optical axis of the light guide is clearly observed to see minute irregularities on the skin surface. This skin observation device is characterized in that it is configured so that it can be set at any angle that can be set.

<Example> Hereinafter, an example of the skin observation device according to the present invention will be described in detail based on the drawings.

In FIG. 1 showing a schematic configuration of the present invention, reference numeral 1 is an image fiberscope, and the tip 1a of this image guide scope 1 is used as an image guide for transmitting images, as shown in FIG. 6 and a light guide 7 for illuminating the subject are constructed such that their respective optical axes 8 and 9 form a predetermined angle within the range of angles at which minute irregularities on the skin surface can be clearly observed. The image guide 6 and the light guide 7 can be fixed at a constant angle θ within the above-mentioned predetermined angle range, or the light guide 7 can be attached with a remotely controllable angle adjustment mechanism to adjust the angle as desired. It would be nice to be able to make fine adjustments. This adjustment mechanism does not particularly require a limited gold coating, but for example, a gear may be attached to the side of the light guide 7, and an arc-shaped gear receiver may be installed inside the covering member of the image guide 6 and the light guide 7 to receive this gear. It is also possible to install the (rack) with a 'fc mechanism and modify the rotation of the gear so that the light guide 7 moves in an arc along the gear receiver within the range of the predetermined angle with respect to the image guide 6. .

As shown in FIG. 1, the tip 1a consisting of the image guide 6 and the light guide 7 is connected to an interface IC via a conduit 1b. connected. That is, the image guide 6 is connected to the ITV camera 2, and the light guide 7 is connected to the light source 4.

In addition, in the present invention, the ITV camera 2 and the light source 4
9. Use the one commonly used for this type of equipment. For example, a Halodan lamp may be used as the light source 4.

511ait of the image fiber scope 1: It is preferable to make the size as small as possible and improve the operability. Therefore, it is preferable that the angle θ is within 45 degrees. However, if the angle θ is less than 45 degrees, Considering that the sharpness of the irregularities on the skin shown in the figure is poor and is stable beyond 45 degrees, it is desirable that the angle θ is at least 45 degrees and in the vicinity of 45 degrees.

Note that a TV monitor 3 is connected to the ITV camera 2, but this TV monitor 3 is not particularly important, and it is sufficient to use one that is normally used for this type of equipment, and these image fiber - Coop 1, ITV camera 2.
It is preferable that the light source 4 for the TV monitor 3 is housed in a cabinet 5 to ensure operability and maintainability.

<J! /+$-Iishi''〉 Using a 2m image scope 1 consisting of a 30,000-pixel image guide °6 and a 49N" light guide 7 and a 100W Halodan light source 4, the optical axes of the image guide 6 and light guide 7, respectively. The unevenness of the facial skin was observed by variously changing the angle formed by 8 and 9.

The results are shown in FIG. 3, and it was confirmed that when the angle of each optical axis was set to 45° or more, the unevenness became clearer.

<Effects of the Invention> The skin observation device according to the present invention is configured such that the angle between the optical axis of the image guide and the optical axis of the light guide is set at an angle where minute irregularities on the skin surface can be clearly observed. In particular, minute undulations of the skin can be fully observed. i.When observing the skin, there is no need to place the ITV camera close to the customer's face, it is sufficient to place a small image fiberscope close to the customer's face, and there is no need for large-scale lighting, so it does not make the customer nervous. You can observe it in its natural state without forcing it. Therefore, observations can be made accurately without causing discomfort to the customer.

In short, according to the 8A device of the present invention, it is possible to select the most suitable cosmetics for the customer.
