OminiVision Releases Four Smartphone Sensors for Greater Dynamic Range Enhanced Noise Control

OminiVision, which has been acquired by the Chinese consortium, has released four new smartphone sensor components, promised to bring greater dynamic range and better noise control.

According to reports, these four sensors use OminiVision's second-generation PureCel Plus and PureCel Plus-S pixel technology to enhance camera performance.

To increase the dynamic range, OminiVision adds the Full Well Capacity of the new sensor, which means that each pixel has the ability to collect more light. The dynamic range of the new sensor is reported to have increased by 20% compared to previous models.

In addition to the overall dynamic range, OminiVision also takes advantage of a new dynamic range technology called zHDR. By dividing the pixels in a zigzag pattern on the photosensitive element, zHDR can simultaneously capture images taken with two different exposure values ​​(slight overexposure and slight underexposure). Subsequently, the data on the two images is intelligently combined, resulting in a further increase in dynamic range.

The pixels on the new sensor are arranged in a new structure that enhances light collection while reducing noise. This capability is due to the combination of a new composite metal matrix (CMG) and deep trench isolation (DTI) that reduces light pollution between pixels.

According to OminiVision, these two technologies increase light sensitivity by 12.5%. When the lighting conditions in the shooting environment are not ideal, it will play its part.

OminiVision's new sensor offers two different resolutions of 16 megapixels and 20 megapixels. It also enhances low-light shooting with a different filter array, but at a certain resolution. Compared with the previous generation of photosensitive elements, they also added phase detection autofocus and support 4K video shooting.

It is reported that OminiVision's new photosensitive components will be applied to the production of smartphones in the first quarter of 2017.
