Sony patent shows single shot HDR image sensor


A new Sony patent (filed in July, published in late October) shows an amazing image sensor, that is able to exposure individual pixels of a photo differently. This way you would be able to take an HDR shot, without having to stack different exposures together.

This image sensor achieves the technology on a per-pixel basis, rather than blending multiple shots together. So according to the patent, dark pixels, like for example shadows, would become long exposure pixels, while bright areas become short exposure pixels.

As someone on Sony Alpha Rumors already pointed out, taking pictures of fast moving objects could end up in a weird looking photo cause of the different exposure times on each pixel. But luckily enough Sony has a solution for this problem, it’s called the sensitivity-specific interpolation process. What this process does is simply combine a short and a long exposure image to remove existing blur (actually a bit like multi-exposure HDR).

Just imagine how cool this new sensor would be for capturing HDR timelapse videos without much post processing work! You can get more detailed information on the patent page here.
