【解説】NSFW定点カメライラスト生成

# 1.はじめに

　この記事では、NSFWな定点カメラ (fixed-point_camera) のイラスト生成方法を解説していきます。

　定点カメライラストとは、特定の箇所に設置されたカメラから撮影されたようなイラストの事です。一般的には、同じアングルでの複数イラストが提示されます。

　なお、これに関しては、全年齢対象だと画像編集AIを利用すれば、比較的簡単に実現できます。

　例えば、WebサービスのNano Banana（Gemini 2.5 Flash Image, Gemini 3 Pro Image）やローカル環境で動作するQwen-Image-Edit-2509などです。

　一次創作なら日本語対応を考えて前者が、二次創作なら著作権的都合を考えて後者がオススメです。

```

Place the girl with the halo from the second image on the corner of the bed in the first image, and have her smile at the viewer.

```

```

Place the angel girl in the second image to the right of the girl in the first image and have the two talk.

```

```

Two girls smiling happily and kissing

```

```

Have the girl with the halo in the second image and the angel girl in the third image sit together on the corner of the bed in the first image. They close their eyes and hug each other.

```

　ただし、NSFWの場合はNano Banana（Gemini 2.5 Flash Image）は利用規約的に難しく、Qwen-Image-Edit-2509は機能的に難しい点があります。

　その為、別のアプローチを取っていきます。

# 4.解説

　舞台画像を生成した後に、各キャラ画像を追加レイヤーとして生成・統合するアプローチをしています。

1. 舞台画像（縦横2048px）を用意する。（画像生成し、アップスケーラー等で高解像度化する）

2. 舞台画像からキャラを配置したい領域（縦横1024pxや1280pxや1536px）を切り抜く。

　※切り抜き用のスクリプト例（Misskey.io配置中｛2025/11/16現在｝）

https://media.misskeyusercontent.jp/io/d9ecc293-fd74-4a94-b5ca-e7293a75bdc7

3. 舞台切り抜き画像（ベッドやその横の床など）でキャラ配置予定箇所に色ラフ（落書き程度で良い）を加える。

4. 上の画像を対象にWebUIのimg2imgタブのLoopbackスクリプト（Denoising strengthを強くしながらimg2imgを繰り返す機能。例：0.35→0.6）を実行する。

　?なるべく舞台の構図を変えずに、その舞台にあったキャラのポージングを用意する為。舞台画像を分割しているのは、高解像度画像を対象に再生成すると時間がかかるのと、illustrious系の生成対象の現在最大解像度は「縦横1536px」とされている為。

　↓

5. キャラの箇所を自動切り抜き（＋手動修正）する。

6. 舞台画像に切り抜きキャラ画像を乗せる。

　?舞台画像とキャラ画像を統合する為の下準備の為。

7. キャラ画像の箇所をマスク（少し大きめにキャラ全体を包む形）し、Inpaint + ADetailer（Denoising Strength：0.35前後）を行う。そのInpaintの際はControlNet（Control Mode：Prefer ControlNet）を使用する。※参照：「2. 前提条件」

　?なるべく細部の破綻を防ぎつつ、舞台画像とキャラ画像を馴染ませる為。

　この結果として、定点カメライラストの生成ができています。

　このアプローチでは1組のカップルのみを対象にしましたが、舞台画像に複数カップルの画像を乗せて、orgy（複数のカップルやグループでの性行為）の構図にもできます。

　また、ADetailerのプロンプト欄では、検出領域ごとにプロンプトを変える為の"[SEP]"という構文が存在しています。それにより、同じ画像内の複数キャラに別々のプロンプトを適用させるような事も可能です。（ただし、それらのキャラがADetailerに検出される事が前提です。また、検出される順序は任意であり、完全な対応が保証される訳ではありません）

# 5. おわりに

　コンピュータ用語の一つに「枯れた技術」というものがあります。これは一見ネガティブな用語に見えますが、そうでもないものです。

　「枯れた技術」とは、多くの人が利用していった中で、多くの検証や修正が行われ、安定性と信頼性が非常に高くなった技術の事を言います。

　この点で、SDXL系列の画像生成AIは「枯れた技術」の一つになってきていると思います。

　その技術を利用する為の知見がコミュニティに蓄積され、いざ利用しようとすれば手に届き、何か困った事があれば解決策が用意されている事が多いです。

　しかし、「枯れた技術」は限界が見えてきている技術という側面もあります。多くの人が改善してきたからこそ、残っている改善点は対応が難しいものになりがちです。

　ただ、たとえ完全に「枯れた技術」であっても、他の技術と組み合わせたり、生成前後の作業手順を工夫したりする事で、対応できる余地があります。

　あなたの創意工夫が、あなたの成果物を何ステップもアップグレードさせます。
