- a filter pad insertion port 15b for inserting the filter pad 40 is formed on the side surface of the main body 11 of the photographing assist jig 10 of the present embodiment. Further, although omitted in FIG. 13, the filter pad insertion port 15b is provided with a cover to prevent external light from entering.
- the user switches the filter pad 40 between the first shooting mode and the second shooting mode, and uses the filter pad 40 corresponding to the shooting mode as the shooting assist jig 10. It is inserted inside the main body 11.
- the photographing assist jig 10 and the skin photographing apparatus 20 of each of the above embodiments are configured to use the inner camera 32 of the smartphone 30, but may be configured to use the outer camera (not shown) of the smartphone 30. Since the performance of the outer camera is generally higher than that of the inner camera 32 of the smartphone 30, there is an advantage that the use of the outer camera enables highly accurate skin analysis using high-quality images. In this case, in order to support various smartphones 30, it is desirable to provide a filter pad 40 different from the filter pad 40 of each embodiment.
- the skin photographing apparatus 20 uses a smartphone 30, but a terminal such as a tablet may be used as long as it has the same functions as the smartphone 30 in the present specification. Since the photographing auxiliary jig 10 has a simple structure and can be easily manufactured to an arbitrary size, it can be manufactured according to the size of the tablet. Even in this case, since the skin photographing apparatus 20 has the necessary functions as in each of the above-described embodiments, it is possible to easily perform imaging for skin analysis.
- each member of the photographing auxiliary jig 10 may be joined and integrated with an adhesive or the like as described above, or may have an assembled structure that can be partially disassembled. If it can be stored compactly as an assembled structure, for example, it can be used on the go, and the user can use the skin photographing apparatus 20 of the present invention every day in order to manage the condition of the skin. ..

Abstract
Description
本発明の撮影補助治具10は、図1に示すように、ユーザが所有するスマートフォン(携帯端末)30とともに用いられ、ユーザ自身の肌を撮影し、スマートフォン30にインストールされた肌分析アプリケーションで肌の状態を簡易に分析するために用いられる。なお、本明細書におけるスマートフォン30には、ケースやカバーで覆われているスマートフォン30も含まれる。
図1及び図2に戻り、上記第1実施形態の撮影補助治具10を肌撮影装置20として使用する場合を説明する。図1及び図2に示すように、肌撮影装置20は、スマートフォン30を撮影補助治具10の本体11の内部に挿入し、スマートフォン30がスマートフォン保持部17に保持された状態(使用状態)で使用するものである。肌撮影装置20は、使用状態において、正面板12を肌に押し当てるように接触させて肌表面を撮影する。すなわち、撮影の際には、撮影補助治具10の本体11の内部が、本体11の外部の光を遮断した遮光状態となり、照明光であるスマートフォン30のディスプレイ31のフラッシュが、照明手段用の開口16bを介して肌撮影窓12a内の肌に照射され、肌の表面或いは肌の表層部分で反射した光のみが、撮影手段用の開口16aを介してスマートフォン30の内側カメラ32に入射することになる。このように、肌撮影装置20は、撮影補助治具10の外部の光である環境光が撮影補助治具10の内部に侵入しないように肌に接触させた状態で撮影できるため、ディスプレイ31からの光以外の不要な光を内側カメラ32で撮影してしまうことを防ぐことができる。そして、スマートフォン30の肌分析アプリケーションは、このように撮影された画像データを用いて、撮影モードに対応する分析を行う。
第3実施形態の肌撮影装置20は、第2実施形態の肌撮影装置20とは異なり、図10に示すように、アタッチメント70を撮影補助治具10に装着して使用し、肌の皮脂量を分析する皮脂撮影(第3の撮影モード)を行うものである。図10及び図11に示すように、アタッチメント70は、本体11の先端部の形状に沿ってキャップ状に形成されている。また、アタッチメント70は、アタッチメント70の前面の挿入部(図示しない)に挿入して使用する皮脂反応シート71を有している。皮脂反応シート71は、第3の撮影モードを実行する際にアタッチメント70に装着して使用する。アタッチメント70の前面の内側面は、皮脂反応シート71を装着したときに、皮脂反応シート71の皮脂反応部71aが露出するように、中央部が開口している。第3の撮影モードでは、皮脂反応シート71が装着されたアタッチメント70を本体11に被せたときに、アタッチメント70の前面の内側面に露出した皮脂反応シート71の皮脂反応部71aを撮影する。なお、アタッチメント70の挿入部の形状は、全体がいわゆるポケットのような形状をしており、皮脂反応シート71を挿入したときに、皮脂反応部71aがちょうど中央に配置されるように形成されている。また、挿入部の幅は、皮脂反応シート71の幅より僅かに広く形成され、挿入部の幅方向の内側面が皮脂反応シート71を挿入する際のガイドとなるため、皮脂反応シート71をスムーズに挿入できる。
上記実施形態では、背面板13との間でスマートフォン保持部17を構成する仕切り板16を1枚としているが、図12に示す第4実施形態では、仕切り板16を2枚とした構成としている。図12では、同一形状の2枚の仕切り板16によって、仕切り部が構成されており、それらの仕切り板16は幅の狭い空間をなすように互いに平行に配置されている。フィルタパッド40は、この空間に着脱自在に収納される。また、それぞれの仕切り板16の撮影手段の開口と照明手段用の開口は、一方の仕切り板の開口と対向する位置に形成されており、2枚の仕切り板16の開口部を構成する。本実施形態のフィルタパッド40は、図13に示すように、2つの異なるフィルタパッド40を使用する。図13の(A)は、第1の撮影モードで使用されるものであり、撮影手段用の偏光フィルタと照明手段用の偏光フィルタが内蔵されている。また、図13の(B)は、第2の撮影モードで使用されるものであり、撮影手段用の偏光フィルタが内蔵され、中央部は開口されている。
