Canon Files Patent Application to Expand Sensor DR
Canon has recently filed a patent application for a solution that would allow digital cameras to faithfully capture high-contrast scenes in a single take. Photography Bay reports that the patent application describes a process whereby different exposure times are assigned to different photosites on the sensor to ensure highlights are not blown out and shadows are not blocked up. If you are interested in the technical details, you can read the entire patent application online.

Can the same technology be used for different filter effects e.g. ND Grad?

actually this would be WAY better than a grad filter as it actually automatically mask the exact pixels that would go overexposed, while a grad filter makes a rather unprecise and unnatural effect!

Well, you may laugh at me now but I was thinking about the idea for quite a few years! Not at pixel level like what Canon has patented but more in the line of a digital ND Grad or selective application of dark areas (masks?) as required. I wonder what took Canon (or others) so long to come up with the idea? Probably something to do with processor speed. I should have patented the idea anyway
