Description

本発明は、光を照射することで毛髪成長の促進もしくは毛髪成長の抑制を行う光毛髪成長調節装置に関するものである。   The present invention relates to an optical hair growth control apparatus that promotes hair growth or suppresses hair growth by irradiating light.

毛（体毛）は成長期から退行期、休止期というサイクルで変化する毛周期を有することが知られている。そして既存の医療用レーザ等で見られるような細胞形態上の変化が生じることがない光量や光エネルギーを持つ光を上記の休止期において行えば、毛周期の成長期における毛の成長が早く進むことが確認されているとともに、細胞の破壊が生じることがなくて火傷等の副作用発生が無いことも確認されている。また、上記毛周期における成長期に光照射を行えば、毛の成長が効果的に抑制されることも確認されている。なお、休止期や成長期に細胞形態上の変化が生じないレベルの光照射を行うと、毛髪の成長が促進されたり抑制されたりする理由は明らかではないが、ＲＮＡレベルでの分析結果では上記光照射によって炎症性サイトカインの活性化が起きていることから、この炎症性サイトカインの活性化によるものと考えられている。   It is known that hair (body hair) has a hair cycle that changes in a cycle from a growth phase to a regression phase and a resting phase. Then, if light having a light quantity or light energy that does not cause a change in cell morphology as seen with existing medical lasers or the like is performed in the rest period, hair growth in the growth period of the hair cycle progresses quickly. It has also been confirmed that there is no destruction of cells and no side effects such as burns. It has also been confirmed that hair growth is effectively suppressed by light irradiation during the growth period of the hair cycle. It is not clear why the growth of hair is promoted or suppressed by light irradiation at a level that does not cause changes in cell morphology during the resting or growing phase. Since the activation of inflammatory cytokines is caused by light irradiation, it is considered that this is due to the activation of inflammatory cytokines.

ところで、上記のような毛髪成長調節用の光を人体の皮膚に照射することで、毛の成長の促進あるいは抑制を行うにあたり、人体の光照射対象部にのみ光を当てることができればよいが、光照射対象部は人によって異なる上に、同じ部位に光を当てるとしてもその部位の形状や大きさには個人差があるために、光照射対象部以外のところにも光を照射してしまうことが生じる。人体表面でも光を過度に当てることは好ましくない部位が存在していることから、尚更問題となる。 However, by irradiating the light for hair growth regulation, such as described above to human skin, in performing promotion or inhibition of hair growth, it is if it is possible to shed light only the irradiated target portion of the human body, The light irradiation target part varies depending on the person, and even if light is applied to the same part, the shape and size of the part vary depending on the individual, and therefore light is irradiated to places other than the light irradiation target part. That happens. Even on the surface of the human body, it is a further problem because there are sites where it is not desirable to apply excessive light.

レーザを用いた脱毛装置などのように施療者が装置を扱うものでは、皮膚の導電率の計測、あるいは皮膚への接触を確認することができるものを、施療者が被治療者の光照射対象としては好ましくない部位への光照射を行ってしまうことを避けるために利用したものが存在しているが、上記装置では、照射対象とする部分であるか照射対象としない部分であるかの判断を装置側でできないために施療者が行っており、被治療者が単独で使用する装置に適用することができない。
特開２００１−２９２８２５号公報 In the case where the user handles the device, such as a hair removal device using a laser, the user can measure the conductivity of the skin or confirm contact with the skin. Is used to avoid irradiating light to an unfavorable part, but in the above apparatus, it is determined whether it is a part to be irradiated or a part not to be irradiated Since the treatment cannot be performed on the device side, the treatment is performed, and the treatment cannot be applied to a device used alone.
JP 2001-292825 A

本発明は上記の従来の問題点に鑑みて発明したものであって、光照射を安全に行うことができる光毛髪成長調節装置を提供することを課題とするものである。   This invention is invented in view of said conventional problem, Comprising: It aims at providing the optical hair growth control apparatus which can perform light irradiation safely.

上記課題を解決するために本発明に係る光毛髪成長調節装置は、毛髪の成長を調節する光を人体の光照射対象部に照射する毛髪成長調節用光照射部と、人体の計測のための光を人体の光照射対象部に照射する計測用光照射部と、該計測用光照射部から照射されて上記光照射対象部で反射した光を受光する受光部と、上記受光部で受光した光の情報を演算処理して光照射対象部の３次元推定形状を出力する処理部と、処理部による演算結果に基づいて毛髪成長調節用光照射部からの光照射を上記光照射対象部に対して行うか否かを判断する判断部とを有していることに特徴を有している。 In order to solve the above-described problems, the optical hair growth control apparatus according to the present invention includes a light irradiation unit for hair growth adjustment that irradiates a light irradiation target part of a human body with light for adjusting hair growth, and a measurement for measuring a human body. A measurement light irradiating unit that irradiates light to a light irradiation target part of a human body, a light receiving unit that receives light reflected from the light irradiation target part and reflected from the light irradiation target part, and received by the light receiving part A processing unit that computes information of light and outputs a three-dimensional estimated shape of the light irradiation target part, and light irradiation from the light irradiation part for hair growth adjustment based on the calculation result by the processing part to the light irradiation target part It has the characteristic that it has the judgment part which judges whether it performs with respect to it.

上記判断部は上記推定形状が人体の眼球形状と同じである場合に光照射対象部に対する毛髪成長調節用光照射部からの光照射を行わないと判断するものであると、特に眼に対する安全性を高めることができる。 When the determination unit determines that the light irradiation from the hair growth adjustment light irradiation unit to the light irradiation target unit is not performed when the estimated shape is the same as the eyeball shape of the human body, the safety to the eyes is particularly obtained. Can be increased.

上記判断部は上記推定形状が一定周期の凹凸形状である場合に光照射対象部に対する毛髪成長調節用光照射部からの光照射を行わないと判断するものであってもよく、この場合、皮膚の病変部に対して危険な光を照射するおそれが低くなる。 The determination unit may determine not to perform light irradiation from the light irradiation unit for hair growth adjustment on the light irradiation target unit when the estimated shape is an uneven shape with a constant period. The risk of irradiating the lesion with dangerous light is reduced.

上記処理部は光切断法によって光照射対象部の断面の曲率を求めてこれを出力するものであり、上記判断部は求められた曲率が人体の眼球の曲率と同じである場合に光照射対象部に対する毛髪成長調節用光照射部からの光照射を行わないと判断するものであってもよい。眼球に対する安全性を比較的簡単に向上させることができる。 The processing unit is designed to output it in search of curvature of the cross section of the light irradiation target portion by the light-section method, light irradiation target when curvature the determination unit was determined is the same as the curvature of the human eye It may be determined not to perform light irradiation from the light irradiation unit for hair growth adjustment on the part. The safety for the eyeball can be improved relatively easily.

前記計測用光照射部は特定方向に偏光した光を照射するものであり、前記受光部は受光した光の偏光情報を求められるものであることが好ましい。より正確な処理や判断を行うことができるものとなる。   Preferably, the measurement light irradiating unit emits light polarized in a specific direction, and the light receiving unit is required to obtain polarization information of the received light. More accurate processing and determination can be performed.

本発明は、計測用光照射部から照射した光の反射光を基に、光照射対象部の３次元推定形状を求め、光照射対象部が毛髪成長調節用光照射部の光を当ててよいものかどうかが判断されて光照射が制限されるために、眼球などの光を当てないことが好ましいところへの光照射がないものであり、安全に使用することができる。 In the present invention, the three-dimensional estimated shape of the light irradiation target portion may be obtained based on the reflected light of the light irradiated from the measurement light irradiation portion, and the light irradiation target portion may shine the light of the hair growth adjustment light irradiation portion. Since it is determined whether or not the light is applied, the light irradiation is limited. Therefore, it is preferable not to irradiate light such as an eyeball, and the light can be used safely.

以下、本発明を添付図面に示す実施形態に基いて説明すると、図１において、図中１は毛髪の成長を調節する光を人体の光照射対象部に照射する毛髪成長調節用光照射部であり、たとえばキセノンフラッシュランプを光源としている。   Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. In FIG. 1, reference numeral 1 denotes a light irradiation unit for hair growth adjustment that irradiates a light irradiation target portion of a human body with light for adjusting hair growth. For example, a xenon flash lamp is used as a light source.

図中２は人体の計測のための光を人体の光照射対象部に照射する計測用光照射部であり、ここではライン光を人体の皮膚表面９に対して斜め４５°方向から照射するものを用いている。   In the figure, reference numeral 2 denotes a measurement light irradiating unit that irradiates the light irradiation target part of the human body with light for measuring the human body. Here, the line light is applied to the skin surface 9 of the human body obliquely from a 45 ° direction. Is used.

上記計測用光照射部２から照射されて上記皮膚表面９における光照射対象部で反射した光は、光照射対象部の直上に配置したＣＣＤカメラからなる受光部３で受光されて電気信号に変換される。   The light irradiated from the measurement light irradiation unit 2 and reflected by the light irradiation target portion on the skin surface 9 is received by the light receiving unit 3 including a CCD camera arranged immediately above the light irradiation target portion and converted into an electrical signal. Is done.

斜め方向からライン状の光を照射するために、受光部３は凹凸形状の高さ変化を計測することができるものであり、また計測用光照射部２及び受光部３を皮膚表面９に沿って光照射対象部の範囲内で移動させることによって、３次元形状データを得ることができる。   In order to irradiate the line-shaped light from an oblique direction, the light receiving unit 3 can measure the height change of the concavo-convex shape, and the measurement light irradiating unit 2 and the light receiving unit 3 are arranged along the skin surface 9. Then, the three-dimensional shape data can be obtained by moving within the range of the light irradiation target part.

なお、図１において、図中４は受光部で受光した光の情報を演算処理する処理部であり、画像記憶部４１と高さ算出部４２と三次元形状データ記憶部４３並びに三次元形状データ作成のために計測用光照射部２の光の照射位置を計測する位置計測エンコーダ４５からの出力に応じて計測タイミングを定める計測タイミング発生部４４で構成されている。図２に３次元形状データを得るためのフローチャートを示す。   In FIG. 1, reference numeral 4 in the figure denotes a processing unit that performs calculation processing on the information of light received by the light receiving unit, and includes an image storage unit 41, a height calculation unit 42, a 3D shape data storage unit 43, and 3D shape data. For the creation, the measurement light generator 2 includes a measurement timing generator 44 that determines the measurement timing in accordance with the output from the position measurement encoder 45 that measures the light irradiation position. FIG. 2 shows a flowchart for obtaining three-dimensional shape data.

ところで皮膚表面９に投光してその反射光を計測する場合、皮膚表面９の反射と皮膚内部を通過した反射光とが混在することになる。しかし、皮膚表面９での反射光は、偏光は照射光と同様の偏光であるが、皮膚内部を通過した光は内部組織による偏光角度の変化の影響を受けることから、ここでは照射する光を偏光フィルター２０によってある一方向に偏光した光とし、受光部３の前に照射光と同じ偏光方向の偏光フィルタ３０を設置することによって、皮膚表面９での反射光のみが受光部３に至るものとし、これによって皮膚表面９の３次元形状計測を正確に行えるようにしている。   By the way, when light is projected onto the skin surface 9 and the reflected light is measured, the reflection of the skin surface 9 and the reflected light that has passed through the skin are mixed. However, the reflected light from the skin surface 9 is polarized in the same manner as the irradiated light, but the light that has passed through the skin is affected by the change in the polarization angle due to the internal tissue. Light that is polarized in one direction by the polarizing filter 20 and the polarizing filter 30 having the same polarization direction as the irradiation light is installed in front of the light receiving unit 3, so that only the reflected light from the skin surface 9 reaches the light receiving unit 3. Thus, the three-dimensional shape measurement of the skin surface 9 can be accurately performed.

上記のようにして得られた三次元形状データは、判断部５において予め定めた形状と一致するかどうかによって、光照射対象部３に毛髪成長調節用光照射部１からの光を光照射対象部に照射するかどうかを判断し、照射してもよいとの結果が出た場合にのみ、毛髪成長調節用光照射部１からの光を光照射対象部に照射する。   Depending on whether or not the three-dimensional shape data obtained as described above matches the shape determined in advance by the determination unit 5, the light irradiation target unit 3 is irradiated with the light from the hair growth adjusting light irradiation unit 1. The light irradiation target part is irradiated with light from the hair growth adjusting light irradiating unit 1 only when it is determined whether or not to irradiate the part and a result indicating that irradiation may be performed is obtained.

判断部５による処理の一例を下記に示す。眼球が有している曲面形状を上記の予め定めた形状とした場合、図３に示すようなＫ×１のライン状のマスクを設定する。眼球は球形であるため、Ｋ個のマスクの各点において、それぞれの点で隣接する高さデータから図４に示すように接線を求めてその方向と直交する方向Ｐを求める。円の場合、注目点と隣接する３点から求めた直交方向は円の中心で交叉し、かつその半径Ｒが眼球と同等となるため、各点の方向Ｐと半径Ｒから中心位置候補座標を求める。この処理により、中心位置とみられる位置に、ある度数以上の中心候補位置が算出されたなら眼球と同じ曲面形状が存在していると判断する。この時、判断部３は毛髪成長調節用光照射部１による照射光を発生させずにおく。図５に上記処理のフローチャートを示す。   An example of processing by the determination unit 5 is shown below. When the curved surface shape of the eyeball is the above-described predetermined shape, a K × 1 line-shaped mask as shown in FIG. 3 is set. Since the eyeball is spherical, at each point of the K masks, a tangent is obtained from height data adjacent at each point as shown in FIG. 4, and a direction P orthogonal to that direction is obtained. In the case of a circle, since the orthogonal direction obtained from three points adjacent to the point of interest crosses at the center of the circle and the radius R is equivalent to that of the eyeball, the center position candidate coordinates are determined from the direction P and the radius R of each point. Ask. With this process, if a center candidate position of a certain frequency or more is calculated at a position considered as the center position, it is determined that the same curved surface shape as the eyeball exists. At this time, the determination unit 3 keeps the irradiation light from the hair growth adjusting light irradiation unit 1 from being generated. FIG. 5 shows a flowchart of the above processing.

皮膚にブツブツとした突起がある場合も光照射を控えなければならないが、この場合、前記３次元形状データにＭ×Ｍの平均値フィルターをかける。この平均値フィルターは、皮膚が有している曲面形状を除去するためのもので、Ｍの値は部位によって異なり、頬部の場合はＭの値を大きくし、腕、足の場合は頬部の場合よりもＭの値を小さく設定する。次に、元の３次元形状データから上記平均値フィルターをかけた３次元データを差し引くことによりブツブツのような微小形状のみが残る（図６参照）ことになり、更に微小形状が残っている３次元データを高さ方向のある値で二値化して、ある高さ以上の部位が所定値以上存在している時は、皮膚表面９に微小な凹凸形状があると判断して毛髪成長調節用光照射部１からの光照射はしない。図７にこの処理のフローチャートを示す。なお、図中のｋの値は、凹凸形状の周波数に相当することから、ブツブツ形状のサイズと計測分解能とから決定する。ちなみにブツブツ形状の約３倍程度を目安とする。 Even if there are bumps on the skin, it is necessary to refrain from light irradiation. In this case, an M × M average value filter is applied to the three-dimensional shape data. This average value filter is for removing the curved surface shape of the skin. The value of M varies depending on the part, and in the case of the cheek, the value of M is increased. The value of M is set smaller than in the case of. Next, by subtracting the three-dimensional data that has been subjected to the above average filter from the original three-dimensional shape data, only a minute shape such as a stubby remains (see FIG. 6), and a further minute shape remains. Dimensional data is binarized with a certain value in the height direction, and when there are more than a certain part over a certain height, it is judged that the skin surface 9 has a minute uneven shape and is used for hair growth control The light irradiation from the light irradiation unit 1 is not performed. FIG. 7 shows a flowchart of this process. The value of k in the figure is determined from the fact that corresponding to the frequency of irregular shape, the size and the measurement resolution of the rash shape. By the way, about 3 times the rough shape is a standard.

同様の方法で眼球部の周囲にある毛の有無も確認できるために、眼球部周囲の毛であるということが判定できた場合も照射しない。毛の有無の認識も行う場合は、前記のような３次元形状計測ではなく、皮膚表面形状と平行方向にライン状の光を照射してラインセンサで反射光を受光することで行ってもよく、この場合、毛の有無の判断が容易となる。ただし、この場合は皮膚の曲面形状が計測ミスの原因となるために、図９に示すように光学部２，３を枠８で囲んで枠８を皮膚に押し当てることで皮膚の曲面形状の影響を少なくすることが好ましい。   Since the presence or absence of hair around the eyeball part can be confirmed by the same method, irradiation is not performed even when it is determined that the hair is around the eyeball part. When the presence / absence of hair is also recognized, it may be performed by irradiating the line-shaped light in a direction parallel to the skin surface shape and receiving the reflected light by the line sensor instead of the three-dimensional shape measurement as described above. In this case, it is easy to determine the presence or absence of hair. However, in this case, since the curved surface shape of the skin causes measurement errors, the curved surface shape of the skin is formed by surrounding the optical parts 2 and 3 with the frame 8 and pressing the frame 8 against the skin as shown in FIG. It is preferable to reduce the influence.

ホクロも毛髪成長調節用光照射部１による照射光を当てない方が好ましいところである。このホクロについては、次のようにすることで検出して毛髪成長調節用光照射部１による照射光を当てないようにすることができる。   It is preferable that the mole is not irradiated with the light irradiated by the hair growth adjusting light irradiation unit 1. About this mole, it can detect by doing as follows and can be made not to irradiate the irradiation light by the light irradiation part 1 for hair growth adjustment.

すなわち、ホクロは皮膚表面９に丸い凸部として存在することから、前述のように斜め方向から計測用光照射部２からの光を当てた場合、黒い影が生じることになるために、受光部３で得られた画像に対して、輝度がある値以下の部分を１とする二値化を行うことで、影部を抽出し、次いで図９に示すように影部８１の外接四角形８２を求めて、その範囲内で円形状かどうかの判断を行う。外接四角形８２の範囲内で二値化で１と判断されていない領域８３が存在する方向を認識し、その方向が外接四角形８２の長辺側の場合は短辺を、逆の場合は長辺を円の直径Ｌとする円形状を想定する。   That is, since the mole exists as a rounded convex portion on the skin surface 9, when the light from the measurement light irradiation unit 2 is applied from an oblique direction as described above, a black shadow is generated. The image obtained in step 3 is binarized by setting a portion whose luminance is equal to or less than a certain value to 1, thereby extracting a shadow portion. Then, as shown in FIG. Find and determine if it is circular within that range. Recognize the direction in which there is a region 83 that is not determined to be 1 by binarization within the bounding rectangle 82, and if the direction is the long side of the circumscribing rectangle 82, the short side will be recognized, and if the direction is the opposite, the long side A circular shape with a diameter L of the circle is assumed.

更に二値化画像の輪郭をトレースして、注目画素に隣接する２画素から前述の場合と同様に円の接線方向を求め、次にその接線方向と直交する方向を求める。その直交方向に円の中心が存在するため、この直交方向に想定した円の半径の距離だけ離れた点に投票を行って、二値化像の輪郭の全ての点で同様の処理を繰り返した後、投票された度数がある値以上の座標を円の中心位置があると判断し、二値化像が円形のものの影であったことを認識するのである。図１０にこの動作のフローチャートを示す。   Further, the contour of the binarized image is traced, and the tangential direction of the circle is obtained from the two pixels adjacent to the target pixel in the same manner as described above, and then the direction orthogonal to the tangential direction is obtained. Since the center of the circle exists in the orthogonal direction, voting is performed at points separated by the distance of the radius of the circle assumed in the orthogonal direction, and the same processing is repeated at all points of the contour of the binarized image. After that, it is determined that the coordinates of the voted frequency equal to or greater than a certain value are the center position of the circle, and it is recognized that the binarized image is a shadow of a circular object. FIG. 10 shows a flowchart of this operation.

以上の処理部４では光照射対象部の三次元形状データを求めているが、光切断法によって光照射対象部の断面の曲率を求めるものであってもよく、この場合、判断部５は求められた曲率が予め与えられた曲率、たとえば人体の眼球の曲率と同じである場合に光照射対象部に対する毛髪成長調節用光照射部１からの光照射を行わないと判断する。   In the above processing unit 4, the three-dimensional shape data of the light irradiation target part is obtained, but the curvature of the cross section of the light irradiation target part may be obtained by a light cutting method. When the given curvature is the same as the curvature given in advance, for example, the curvature of the eyeball of the human body, it is determined that the light irradiation target portion is not irradiated with light from the hair growth adjusting light irradiation portion 1.

ところで、前述の計測用照射部２から照射する光を偏光とし、受光部３による受光も偏光フィルター３０を介して行う場合は、光照射対象部が眼球であるか否かでの判断にあたっては、受光量の値を参照することを併用してもよい。すなわち、皮膚組織内部には筋肉のように一定方向に並ぶ組織が存在するために、入射した光の偏光方向が回転する特性があるが、眼球は角膜と水晶体等で構成されているために、眼底内部で反射して眼の外に出てくる光は偏光方向が変化しない。従って、受光部３の前に配置した偏光フィルター３０の角度を入射する光の偏光角度と直交する９０°方向とすると、光照射対象部が皮膚であれば、皮膚内部で偏光が起きて偏光角度が９０°回転した方向で受光してもある程度の光量を得ることができるのに対して、光照射対象部が眼であれば、偏光が起きないために上記受光部３での受光量が非常に小さくなる。この点を利用するのである。   By the way, in the case where the light emitted from the measurement irradiation unit 2 is polarized light and light reception by the light receiving unit 3 is also performed through the polarization filter 30, in determining whether the light irradiation target unit is an eyeball or not, It may be used in combination with referring to the value of the amount of received light. That is, because there is tissue aligned in a certain direction like muscles inside the skin tissue, there is a characteristic that the polarization direction of the incident light rotates, but because the eyeball is composed of the cornea and the lens, The light that is reflected inside the fundus and exits the eye does not change its polarization direction. Therefore, if the angle of the polarizing filter 30 disposed in front of the light receiving unit 3 is 90 °, which is orthogonal to the polarization angle of the incident light, if the light irradiation target unit is skin, polarization occurs inside the skin and the polarization angle. A certain amount of light can be obtained even if light is received in a direction rotated by 90 °. On the other hand, if the light irradiation target part is an eye, polarization does not occur and the light receiving part 3 has a very low light receiving quantity. Becomes smaller. This point is used.

また、計測用照射部２が照射する光の波長を、水の吸収波長である１４３０ｎｍや１９４０ｎｍを含む光とし、反射光での光吸収を計測することで眼と皮膚の区別ができるために、この点を併用してもよい。   In addition, since the wavelength of the light irradiated by the measurement irradiation unit 2 is light including 1430 nm and 1940 nm which are absorption wavelengths of water, and by measuring the light absorption by the reflected light, it is possible to distinguish the eye and the skin. You may use this point together.

偏光のみや光吸収のみで判断を行う場合は、計測用照射部２を点光源、受光部３をフォトダイオードのような１素子の受光手段で形成することができる。   When the determination is made only by polarization or light absorption, the measurement irradiation unit 2 can be formed by a point light source, and the light receiving unit 3 can be formed by a single light receiving unit such as a photodiode.
