- the support base 411 is formed in a substantially rectangular parallelepiped shape as a whole, it is not limited to this shape and may have another shape.
- the support base 411 has an accommodation hole 412 on its upper surface for mounting the imaging device 200 so that the main body 201 of the imaging device 200 is positioned upward and the display 203 is positioned downward.
- the accommodation hole 412 is formed so that the shape of the side wall follows the outline of the display 203 of the imaging device 200 (broken line in FIG. 12A) and has a predetermined depth.
- the imaging device 200 when the imaging device 200 is placed on the mounting table 400 , the imaging device 200 is positioned by the side wall of the accommodation hole 412 .
- the accommodation hole 412 has, on its bottom surface, one or more projections 413 having a predetermined height (but lower than the height of the side walls) and a projection 413 having a predetermined height (but lower than the height of the side walls). has one or more linear projections 416 having The protrusion 413 and the linear protrusion 416 are provided at positions corresponding to the base 227 provided on the user side of the display 203, and support the base 227 from below.
- a space is formed between the display panel 215 of the display 203 and the bottom surface of the receiving hole 412 by the height of the pedestal 227 and the height of the protrusions 413 and linear protrusions 416 . This prevents the display panel 215 from being damaged by the bottom surface of the receiving hole 412 .
- the mounting table 400 supports the vicinity of the grip 202 of the imaging device 200 from the side when the imaging device 200 is mounted in the accommodation hole 412 so that the main body 201 of the imaging device 200 is positioned upward and the display 203 is positioned downward. It has a support stand 414 for The support stand 414 is arranged above the support base 411 and formed to have a predetermined length in the height direction. Also, the surface facing the grip 202 is formed along the outer shape of the grip 202 . It should be noted that the support stand 414 itself need not always contact and support the vicinity of the grip 202 of the imaging device 200, and may only come into contact when the imaging device 200 is tilted, for example.
- the mounting table 400 has a power feeding portion 417 formed at a position facing the lower surface of the display 203 of the imaging device 200 (that is, the surface on which the power feeding port 228 is arranged) when the imaging device 200 is placed in the accommodation hole 412 . It is A power supply terminal 415 is formed on a surface of the power supply unit 417 facing the lower surface of the display 203 and at a position facing the power supply port 228 of the imaging device 200 .

Abstract
Description
<第1実施形態>
1.撮像システム1の概要
本開示に係る撮像システム1は、主に被験者の口腔の内部を撮像し被写体画像を得るために用いられる。特に、当該撮像システム1は、口腔の喉奥周辺、具体的には咽頭を撮像するために用いられる。したがって、以下においては、本開示に係る撮像システム1を咽頭の撮像に用いた場合について主に説明する。ただし、咽頭は撮像部位の一例であって、当然に、口腔内であれば他の部位であっても、本開示に係る撮像システム1を好適に用いることができる。
図3は、本開示の一実施形態に係る撮像システム1の概略図である。図3によれば、撮像システム1は、処理装置100と、当該処理装置100に有線又は無線で通信可能に接続された撮像装置200とを含む。処理装置100は、使用者による操作入力を受け付けて、撮像装置200による撮像を制御する。また、処理装置100は、撮像装置200によって撮像された被写体画像を処理して使用者、対象者等へ処理後の画像を出力する。
本開示に係る撮像システム1は、処理装置100で処理するための画像を撮像する撮像装置200を含む。図5は、本開示の一実施形態に係る撮像装置200の構成を示す斜視図である。図5によると、撮像装置200は、その内面にカメラ211が収容されるとともに、その内部に光源212から照射された光を導光することが可能な本体201、本体201の基端に接続され使用者によって把持されるグリップ202と、本体201の先端に配置される拡散板219と、グリップ202の基端に接続されカメラ211によって撮像された被写体画像を出力可能なディスプレイ203とを含む。
図7Aは、本開示の一実施形態に係る補助具300の構成を示す斜視図である。補助具300は、対象者の口腔内の撮像のために使用される補助的な道具である。したがって、撮像装置200で口腔内を撮像する場合に、必ず必要とするものではなく、使用者又は対象者の所望に応じて使用されなくてもよい。補助具300には、撮像装置200の少なくとも先端側の一部が挿入される。したがって、補助具300は、撮像装置200の邪魔にならず良好な視野を確保するという観点から、透光性を有することが好ましい。
図8は、本開示の一実施形態に係る撮像装置200と補助具300の使用状態を示す概略図である。以下、図7Bの本体312の基端316に配置される各機構について、図8を参照しつつ説明する。まず、撮像装置200が補助具300の基端316に挿入され、先端314近傍まで達すると、撮像装置200のグリップ202の外方向に突出して形成された係合突起217と、補助具300の本体312の内面に向かって形成された係合突起318とが当接する。ここで、本実施形態においては、本体312の係合突起318-1~318-4は、一対の溝319-1a及び319-1b~319-4a及び319-4bによって形成された片317-1~317-4に形成されている。したがって、撮像装置200の係合突起217と補助具300の係合突起318が当接した状態でさらに撮像装置200を挿入する方向に力が加わると、一対の溝319で形成された片317が持ち上げられる。これによって、撮像装置200の係合突起217が、補助具300の係合突起318を越えてさらに挿入される。
図9は、本開示の一実施形態に係る撮像装置200の断面の構成を示す概略図である。図9によると、光源212は、グリップ202の先端側に配置された基板231上に、合計4個の光源212-1~212-4が配置される。光源212は、一例としては、それぞれLEDで構成され、各LEDから所定の周波数帯域を有する光が口腔の方向に向かって照射される。具体的には、光源212から照射された光は、本体201の基端225に入光し、本体201の壁部224によって、拡散板219方向に導光される。拡散板219に達した光は、拡散板219によって口腔内に拡散される。そして、拡散板219によって拡散された光は、被写体である咽頭715等に反射する。この反射光がカメラ211に到達することで、被写体画像が生成される。
図10は、本開示の一実施形態に係る撮像装置200のディスプレイ203の構成を示す斜視図である。ディスプレイ203は、グリップ202の基端側(口腔に挿入される方向Hとは反対側)に配置される。ディスプレイ203は、全体として略直方体形状をし、使用者側(グリップ202が連結される側とは反対側)の面に矩形状に形成された表示パネル215を有する。表示パネル215には、カメラ211で撮像した被写体画像が表示されるが、これまで説明したとおり、本体201、グリップ202及びディスプレイ203が同一直線状に配置されているために、ディスプレイ203に表示された被写体画像を確認しつつ容易に撮像装置200で撮像することが可能となる。
図12Aは、本開示の一実施形態に係る載置台400の構成を示す上面図である。また、図12Bは、本開示の一実施形態に係る載置台400の構成を示す斜視図である。載置台400は、撮像装置200を安定的に載置するとともに、必要に応じて有線ケーブルを介して電源に接続して、載置台400の給電端子から撮像装置200の給電ポートを通じて撮像装置200に電力を供給するために用いられる。
上記実施形態においては、処理装置100と撮像装置200とが、無線又は有線ケーブルを介して通信可能に接続されている場合について説明した。しかし、これに限らず、撮像装置200で撮像された被写体画像は、無線通信によって遠隔に設置されたサーバー装置(例えば、クラウドサーバー装置)に送信し、サーバー装置を処理装置として機能させることも可能である。具体的には、サーバー装置で疾患らしさを判定したり、遠隔に設置された医者用端末装置に送信し、当該装置を処理装置として機能させることで、医者の所見とともに判定したりすることも可能である。
