# 露出拡張
画像のガンマ露出を調整して、明るくしたり暗くしたりします。これにより画像の露出にばらつきを加え、照明やカメラ設定の変化に対してモデルがより堅牢になるようにします。
* Percent: 画像がランダムに明るくまたは暗くなる最大割合を選択します。最大で100%明るく（完全な白）または100%暗く（完全な黒）なります。
## 例
元の画像
-10% Brightness の Exposure Augmentation
+10% Brightness の Exposure Augmentation
## FAQ
露出は明るさとどう違いますか？
露出は、センサーが「受け取った」光の量をシミュレートします。カメラで ISO やシャッタースピードを調整するのと似ています。
Exposure augmentation は、実際の照明条件により忠実です。明るい領域は暗い領域よりも速く明るくなり、画像の階調関係をより自然に保ちます。
