Description

[Technical Field]

[0001] This invention relates to a face lighting stand used when photographing a face. [Background technology]

[0002] 2. Description of the Related Art There are known applications that diagnose and evaluate various skin conditions of a user based on various types of image processing of an image of the user's face. Naturally, the results of the diagnosis and evaluation of the above applications vary depending on the state of the image used. In particular, shadows on the image caused by lighting can have a significant impact, as the application may mistakenly evaluate them as dullness or blemishes.

[0003] Patent Document 1 discloses an illuminated mirror in which light-emitting diodes are arranged at predetermined intervals around a mirror located in the center. The mirror is described as being able to evenly and brightly illuminate almost the entire face, making it easier to apply makeup without forming shadows on the face.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-73174 Summary of the Invention [Problem to be solved by the invention]

[0005] The illuminated mirror described in Patent Document 1 is intended for use when applying makeup while looking in the mirror, but does not take into consideration capturing a good image of the face. After various studies, the inventors discovered that it is difficult to capture a good image of the face by simply illuminating the face from the front, as in the product described in Patent Document 1.

[0006] Furthermore, since the facial images used in the above applications are often taken by beauty consultants at cosmetics manufacturers or by the users themselves, there is a demand for a device that can easily take good images even if the user is not an expert in photography.

[0007] In view of the above circumstances, the present invention aims to provide a face lighting stand that can easily capture good facial images. [Means for solving the problem]

[0008] The present invention is a face lighting stand comprising a base, a first member having a first light and mounted on the base, and a second member having a second light and capable of being held at a predetermined distance from the first member. The first member has a mounting portion so that an imaging device can be installed on the second member side. The first illuminator is configured to emit illumination light toward the second member. The second illuminator is formed in an annular shape that allows a human face to enter, and is configured to emit illumination light toward the inside of the annular shape. [Effects of the Invention]

[0009] According to the present invention, a face lighting stand can be provided that allows good facial images to be easily obtained. [Brief explanation of the drawings]

[Figure 7] 10A and 10B are diagrams showing modified examples of the first member of the face lighting stand. DETAILED DESCRIPTION OF THE INVENTION

[0011] An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing a face lighting stand (hereinafter sometimes simply referred to as a "stand") 1 according to this embodiment. As shown in FIG. 1, the stand 1 includes a base 10, and a first member 20 and a second member 50 arranged on the base 10.

[0012] FIG. 2 is a front view of the stand 1, and FIG. 3 is a right side view of the stand 1. As shown in FIG. The base 10 in this embodiment has a rectangular shape when viewed from above in a plan view, and has four legs 11 that are grounded on the underside, but the shape and structure of the base are not limited to this, and the shape and structure can be freely determined as long as it can be stably installed in a specified environment such as on a table.

[0013] The first member 20 is located at the rear side of the base 10 away from the front, and has a support 21, and an illumination unit 30 and a placement unit 40 attached to the support 21. The support pillar 21 has its lower end fixed to the base 10 and extends upward.

[0014] The illumination unit 30 according to this embodiment is circular when viewed from the front, and includes a circular mirror 31 disposed in the center and an annular first illuminator 32 disposed around the mirror 31. The first illuminator 32 according to this embodiment has a configuration in which a plurality of LEDs (light-emitting diodes) are arranged in a ring shape and covered with a white diffusion plate 32a, but the light source is not limited to an LED, and other means such as a fluorescent lamp may also be used.

[0015] The mounting section 40 is a U-shaped member in a plan view, and as shown in FIGS. 2 and 3, has a pair of mounting surfaces 41 and a stopper 42 provided at the front end of the mounting surfaces 41. The mounting section 40 is fixed to the support 21 by fastening an intermediate section connecting the pair of mounting surfaces 41 to the rear side of the support 21 with a screw. The support 21 is provided with multiple screw holes, and by changing the holes to be used, the height of the mounting surface 41 can be adjusted in multiple stages. The number of screw holes and the height of each hole can be set appropriately taking into account the imaging device, etc. that is expected to be used. The stoppers 42 are formed by bending the front side of each mounting surface 41 upward.

[0016] The second member 50 has a movable support 51 and a second light 52 having an annular shape. As shown in FIGS. 1 and 2, the movable support column 51 is disposed at a position overlapping with the support column 21 of the first member when the stand 1 is viewed from the front. A groove 12a is formed on the top surface 12 of the base 10, between the movable support column 51 and the support column 21. The lower end of the movable support column 51 enters the internal space of the base 10 through the groove 12a and is connected to a plate (not shown) that is disposed in the internal space. This plate has dimensions that prevent it from passing through the groove 12a, so the movable support column 51 is attached so as not to come off the base 10 and so as to be able to move relative to the first member 20 along the groove 12a.

[0017] The second illuminator 52 has a circular inner surface formed by a diffuser plate 53, and a plurality of LEDs (not shown) are arranged inside along a circular shape. The second illuminator 52 is configured so that light emitted from the LEDs arranged inside passes through the diffuser plate 53, causing the entire inner surface to emit light and emitting illumination light toward the inside of the ring formed by the second illuminator 52. The circular shape of the second illuminator 52 is large enough to fit an average-sized human face inside while tilting it, and as an example, the inner diameter is about 300 mm. In this embodiment, the first illuminator 32 and the second illuminator 52 have a simple configuration in which they are turned on and off by a common switch.

[0018] The operation of the stand 1 according to this embodiment configured as above when in use will be described. In the stand 1, the illumination unit 30 has a circular shape that is slightly smaller than the inner diameter of the second illuminator 52, and as shown in Fig. 3, the center of the illumination unit 30 and the center of the second illuminator 52 generally coincide with each other in a front view. Therefore, when the second member 50 is moved along the groove 12a and the movable support 51 is brought into contact with the first member 20 while entering between the pair of mounting surfaces 41, the first member 20 and the second member 50 can be brought into a state where they generally overlap, as shown in Fig. 4. In this state, by turning on the first light 32 and using the mirror 31, the stand 1 can be used as an illuminated mirror when the face is not being photographed.

[0019] Next, the operation when the stand 1 is used for photographing a face will be described. The user moves the second member 50 along the groove 12a to a position a predetermined distance away. In one example, the predetermined distance is about 170 to 200 mm, and in this embodiment, when the second member 50 is moved as far away from the first member 20 as possible along the groove 12a, it is held at the predetermined distance from the first member 20, making the operation easy.

[0020] Next, an imaging device such as a tablet terminal or a smartphone is placed on the pair of mounting surfaces 41, and the imaging device C is set up by leaning it against the lighting unit 30 as shown in Fig. 5. The set up imaging device comes into contact with a stopper 42 located in front, preventing it from slipping off.

[0021] The user turns on the first illuminator 32 and the second illuminator 52, and while aligning the angle with the imaging device C, moves the face into the ring of the second illuminator 52. The entered face Fc is illuminated from the front by the first illuminator 32 and from the surroundings by the second illuminator 52. When the imaging device C is operated in this state to photograph the face, an image of the user's face is acquired and can be used for a desired application such as a skin diagnosis app.

[0022] When the face is lit from the front, the entire face can be illuminated evenly, but shadows can be created by uneven areas such as the nose. Increasing the illumination from the front can weaken or eliminate these shadows, but if the light is too strong, the entire skin will appear whitish in the acquired image, which can affect diagnosis and evaluation. The stand 1 according to this embodiment illuminates the face from the surroundings using the second illuminator 52, thereby eliminating the shadows described above without excessively increasing the light intensity of the first illuminator 32. As a result, it is possible to acquire a facial image that adequately reflects the texture of the skin and is suitable for diagnosis, etc. The inventors' studies also showed that facial images acquired using the stand 1 provided more stable diagnostic results using an application than facial images acquired with illumination only from the front.

[0023] Although the present invention has been described above, the specific configuration is not limited to this embodiment, and configuration changes and combinations within the scope of the present invention are also included.

[0024] First, in the face lighting stand according to the present invention, the first and second members may not move relative to each other and may always maintain a predetermined distance. However, by making the first and second members movable relative to each other, as described above, the mirror can be used as an illuminated mirror even when not in use, which has the advantage of making it easy to keep in the cosmetics section of a store and taking up less space when stored. When making it possible to move relatively, the first member may be the movable side, unlike in the embodiment, but if the front second member is made the movable side, there is an advantage that space can be secured in front when using it as an illuminated mirror, making it easier to perform various tasks such as applying makeup.

[0025] The shape of the illumination unit of the first member does not necessarily have to correspond to the second illumination unit. For example, even if the illumination unit uses a rectangular mirror 31A, as in the illumination unit 30A of the modified example shown in Fig. 6, the illumination unit and the second illumination unit can be overlapped by appropriately setting the dimensions of the illumination unit and the second illumination unit. If the two are configured not to move relative to each other, the degree of freedom in the shape is greater.

[0026] The face lighting stand according to the present invention does not necessarily need to be able to be used as an illuminated mirror. If such use is not anticipated, the face lighting stand may have a planar first light 32A and no mirror, as in the modified lighting unit 30B shown in Figure 7.

[0027] In the face light stand of this invention, there are no particular restrictions on the materials of each part, and metal, synthetic resin, wood, etc. can be appropriately selected and used. Using insert molding, where the metal is located inside, is preferable because it is easy to achieve both appearance and rigidity and does not become excessively heavy.

[0028] The color of the illumination light in the first illumination and the second illumination can be selected as appropriate, but white light (color temperature of about 4500 to 5000 Kelvin) is preferred in terms of having little effect on the facial image. [Explanation of symbols]
