在iOS上假长时间曝光 [英] Fake long exposure on iOS

问题描述

我必须为应用程式加入长曝光相片功能。因为我知道这是不可能的，我不得不假的。它应该像慢速快门或魔术快门。

I have to implement long exposure photo capabilities to an app. Since i know that this is not really possible i have to fake it. It should work like "Slow Shutter" or "Magic Shutter".

很遗憾，我没有办法实现这一点。我知道如何使用相机拍摄图像（通过 AVFoundation ），但我被困在合并他们假的长快门时间。

Sadly i got no clue how to achieve this. I know how to take images with the camera (through AVFoundation) but i'm stuck at merging them to fake long shutter times.

我可能需要操作和组合所有的图像与核心图但我不知道这如何）。也许有一个更好的解决方案。

Possibly i need to manipulate and combine all the images with coregraphics but i'm not sure about this (even the how). Maybe there's a better solution to this.

我会感谢所有的帮助，
谢谢大家！

I would appreciate every help i can get here, thank you people!
