Why Your Phone Camera Needs Computational Photography

课文

1. Modern smartphone cameras rely less on large lenses and more on fast processors that combine multiple quick shots into one clear image.

   现代智能手机摄像头不再依赖大镜头，而是依靠高速处理器，将多张快速拍摄的照片合成一张清晰图像。

2. When you tap to take a photo in low light, the phone captures ten or more frames within a fraction of a second.

   在弱光环境下点击拍照时，手机会在不到一秒的时间内捕捉十张甚至更多帧画面。

3. Its software then aligns these images pixel-by-pixel, removes blur caused by hand movement, and enhances details using AI-trained models.

   其软件随后逐像素对齐这些图像，消除手抖造成的模糊，并利用AI训练模型增强细节。

4. This process, called computational photography, lets small cameras rival much larger DSLRs in certain conditions.

   这种名为计算摄影的技术，让小型摄像头在某些条件下媲美体积大得多的单反相机。

5. Features like Night Mode, Portrait Mode, and Super Resolution all depend on real-time calculations—not just optical hardware.

   夜景模式、人像模式和超分辨率等功能，全都依赖实时计算，而不仅仅是光学硬件。

6. Even zooming digitally feels smoother because the system upscales intelligently instead of simply stretching pixels.

   就连数码变焦也更流畅，因为系统采用智能放大而非简单拉伸像素。

7. Battery life remains stable because optimization happens locally on the device’s neural engine, not via cloud servers.

   电池续航保持稳定，因为优化运算在设备本地的神经引擎中完成，无需依赖云端服务器。

8. As chips grow faster and smarter, future phones may correct lens distortion or simulate shallow depth-of-field entirely in software.

   随着芯片变得更快、更智能，未来手机或许能完全通过软件校正镜头畸变或模拟浅景深效果。
