问题 I am trying to get some HDR related functions working with OpenCV-Python: specifically I'm trying to reproduce the OpenCV C++ HDR tutorial. Unfortunately, the resulting hdr image/array comes out completely white (all values are Inf). Here is an MCVE. 1.jpg, 2.jpg, 3.jpg are all 870 × 580 RGB (Internal RGB KODAK sRGB Display) JPG images with exposure times of 1/3200, 1/800, and 1/200 respectively. I've tested this with 2 other JPG image sets now, one of which is available on Wikimedia. >>>

How to use HDR with custom AVFoundation based Camera app?

由 我的梦境 提交于 2019-12-04 08:24:27
I use the AVFoundation framework to create a custom camera app. Is it possible to capture a photo with HDR for a custom camera app, i.e., is HDR somewhere exposed in the camera api? Jasper Had the same question and found an answer in this SA question. HDR is unique to the Camera.app from Apple and is not available to developers through an API. 来源： https://stackoverflow.com/questions/29085088/how-to-use-hdr-with-custom-avfoundation-based-camera-app
