Rambus Binary Pixel brings single-shot HDR photos to phone cameras


Rambus Binary Pixel brings singleshot HDR photos to phone cameras

Most high dynamic range photography 'cheats' by merging multiple exposures into a composite image, which can lead to blurry shots. While HDR camera technology is catching up and will even let us record HDR video on our smartphones, Rambus believes its new Binary Pixel technology can achieve the effect with less waste. Its new imaging chip tries to replicate the human eye's range through setting light thresholds and oversampling the scene in both space and time. The results are more natural shadows and highlights down to the pixel level, with processing processing fast enough for video. The overall image reportedly suffers from less noise as well. Companies will have to talk to Rambus to implement Binary Pixel, although it's a considered a drop-in technology that should talk to existing processors and camera sensors, whether it's for smartphones or point-and-shoot cameras. Rambus may just want to hurry if it hopes to get noticed -- it's joining an increasingly crowded field.
