Global shutters have arrived in high-end camera tech – but global shutters still have some disadvantages compared to rolling shutter sensors. But what if cameras could shoot both? That’s the idea behind a series of sensors coming from STMelectronics, which can switch back and forth between global and rolling shutters.
Rolling shutters expose one row of pixels at a time, and, while this happens quickly, the fastest-moving subjects can appear distorted. Global shutters expose the entire image at once instead. This solves the fast subject distortion, but rolling shutters are often said to have better dynamic range and low-light image quality.
