# 圖片增強 {#image-enhancement}
|
|||
|
|
|
|||
|
|
具備智慧分析的一鍵自動改善。分析圖片並套用曝光、對比、白平衡、飽和度、銳利度與降噪校正。
|
|||
|
|
|
|||
|
|
## API 端點 {#api-endpoint}
|
|||
|
|
|
|||
|
|
`POST /api/v1/tools/image/image-enhancement`
|
|||
|
|
|
|||
|
|
**處理方式：** 同步（使用 `createToolRoute` factory，直接回傳結果）
|
|||
|
|
|
|||
|
|
**模型套件包：** 基本增強不需要任何套件包。`upscale-enhance` 套件包（5-6 GB）僅在啟用 `deepEnhance` 時使用（透過 SCUNet 進行 AI 降噪）。
|
|||
|
|
|
|||

## 注意事項 {#notes}
|
|||
|
|
|
|||
|
|
- 此工具使用同步的 `createToolRoute` factory，因此會回傳標準回應（而非 202 非同步）。
|
|||
|
|
- `mode` 參數會調整校正的加權方式（例如人像模式對膚色較溫和，風景模式則提升飽和度）。
|
|||
|
|
- 當啟用 `deepEnhance` 且已安裝 `noise-removal` 工具（SCUNet）時，會在標準校正後額外套用一次 AI 降噪。
|
|||
|
|
- analyze 端點適合在實際套用前，預覽將會套用哪些校正。
|
|||
|
|
- 透過自動解碼支援 HEIC/HEIF、RAW、TGA、PSD、EXR 與 HDR 輸入格式。
