The problem with low dynamic range right now lies within the pixel. With a set saturation point, a pixel simply cannot get more light than a certain amount. ‘Binary Pixel’ gets around that by measuring the amount of light that a pixel gets and resetting it when it reaches its peak. This allows for even more light information to pass and improves highlights in both the lighter and darker areas of an image.
The new sensor employs Binary Operation that brings thresholds for light sensitivity for pixels for better low and dark area exposure and Spatial Oversampling for improved range and reduced noise.
At MWC, Rambus demonstrated a fairly basic 128x128-pixel sensor as a proof of concept, but says there would be no difficulty to make higher resolution sensors using currently available technology. The technology integrates easily with current chips and is manufactured using current CMOS technology.
