The capabilities of image sensors are constantly getting better, also in the area of the ubiquitous small smartphone sensors. Sony has developed a new 3-layer stacked high speed CMOS sensor with DRAM. It promises to minimise image distortion and add super slow motion capabilities to future smartphones.
Sony announced the development of the industry’s first 3-layer stacked CMOS sensor for smartphones. Compared to traditional 2-layer sensors, the new Sony sensor features an added DRAM layer. The purpose of this extra layer is to increase data readout speeds and make it possible to capture still images of fast-moving subjects with minimal focal plane distortion (something we also call “rolling shutter”) as well as super slow motion movies at up to 1,000 frames per second in 1080p.
