it's an entirely different shutter process for stills than it is for video. but regardless, see what you want out of it. this technology will not make it into a stills camera for Canon.Unless you want HDR with motion blur and without any additional logic trying to stretch the highlight exposure to match the blur of the shadows exposure. WHICH IS THE ENTIRE POINT OF THE PAPER.
Sure. And thanks to the interleaved sandwich partial-exposure method outlined here, you'll have the same blur on your highlight exposure that you do on your shadows exposure.
Read the journal article. It explains EXACTLY how to do it on the sensor, WITHOUT doing motion detection or anything else.
Quote from after Fig. 12: "the moving object is free from both jerkiness degradation and double image degradation without complicated signal processing "
You've completely missed the entire point of the global shutter mechanism: they're controlling the shutter speed down to 23 microseconds: 1/43,478th of a second. How much more finite do you think you need? They show an example of a 1/65th second exposure, and the entire walkthrough of its operation is applicable to a still image as well as a video.
what you are not considering is the TIME for each exposure - which is from 30s to 1/8000th of a second for stills. if you have a 1s exposure, you're probably effectively taking a .5s exposure and then a 2s exposure to make up the HDR image for a total of 2.5s.
while doing this while you are doing in video, your shutter speed can be finitely more controlled, because, your shutter speed, well is more controlled and far more predictable.
Then you have the complexity of DPAF which aggravates this by a factor of 2.
but really see into it what you want, but there's a reason canon already has global shutter implemented with the single cell memory version of this technology and it's not available on any ILC.
