I'm not sure what you mean by self resetting pixel designs. Do you perhaps means the self-shuttering (rolling shutters) on CMOS sensors?
This is very different. If you oversaturate either a self shuttering sensor or a shuttered CCD, that information is gone. All you know is that this is "100% bright, or more". Your software which turns raw sensor readings into an image makes the area full brightness, and you get blow outs.
With this approach, say the light is bright enough to make a pixel read 567% (if that as possible). A standard sensor would record 100%. This sensor would empty itself five times and record 67%. Then, the algorithmic magic happens which looks at neighboring areas and figures out how many roll-overs happened and adds the 500% back in.
You can't do that perfectly (hence my comment before about an overexposed zebra), and it will introduce new forms of aliasing, kind of like de-bayering the bayer masks makes moiree patterns.
I've seen CMOS pixel designs in the past that can detect saturation and effectively dump the well (reset) repeatedly until saturation no longer occurs.
