According to Photo Rumors, Canon is working on a new sensor that is able to read out single pixels at individual exposure times, ensuring greatest possible dynamic range.

This would be a major breakthrough in digital imaging, going far beyond what is currently possible with Fujifilm’s EXR technology (where two layers of pixels are read out at different exposure times to increase DR). While Fuji’s EXR DR technology already brings a major improvement in DR, Canon’s new sensor could offer a much greater ability to capture high-contrast scenes, as each pixel’s readout time could be adjusted according to the amount of light it captures, reading out pixels capturing bright areas at a much shorter exposure time than pixels capturing dark areas.

Wow, this is really exciting!
