The paper real-time hdr is based upon (http://dx.doi.org/10.1145/3072959.3073592) is from 2017 and says that the method was used with a smartphone GPU and took about 2ms to generate (@1080p). A dsp would be even faster.
people this feature is missing on your phone because old pixels has 1 camera and this task is being accomplished surely while using the 2 cams so they can get different exposures only 2+ camera phones with snapdragon 855 will be the key to know if this is something that can or cant be ported out pixel 4
AnonD-706668, 21 Oct 2019Huh ! They are now flowing the path what Apple did and doing with its older iPhone devices. You didn't think through why they didn't include it in the older models. The likely reason for the omission is the switch from the Pixel Visual Core to the new Pixel Neural core. We could guess that the new Live HDR+ as being more computationally more intensive hence why they couldn't port it to the older model.
YUKI93, 21 Oct 2019Not sure if I fancy HDR+, to be honest. I definitely much prefer total manual control (ISO, sh... moreThat's when you have time. But most people just wanna take out their phone and take a shot.
Google's and Apple's HDR work pretty well. As a P3-owner, I'd say that iPhones still shoot the more realistic ones while Google's HDR makes everything dramatic looking.
I was hoping Dual Exposure will come to P3. But nope... I could live with using it without having a proper live-preview, if that is really a HW-issue.
