Smallest pixel image sensor for high-end smartphones
OMNIVISION has announced the OVB0A, a tiny 200MP image sensor that features the world’s smallest pixel size of just 0.56 µm without compromised high performance. The OVB0A is designed for rear-facing (wide-angle) main cameras in high-end smartphones. With its unique 16-cell binning capability, the OVB0A sensor delivers the best low-light performance in its class. It also features 100% quad phase detection (QPD) for superior autofocus.
“We have not compromised high performance with the smaller die size of the OVB0A image sensor. In fact, OVB0A’s 0.56 µm pixel is not only the first in the world smaller than the wavelength of red light, but its QPD and quantum efficiency (QE) performances also mirror those of our 0.61µm pixel-based OVB0B image sensor in the visible light range,” states Arun Jayaseelan, senior product marketing manager, OMNIVISION. “Leveraging our PureCel®Plus-S stacked-die technology, we can maintain extremely high resolution in the smaller 0.56 µm pixel size, packing 200M pixels into a 1/1.4-inch optical form factor.”
The OVB0A sensor’s selective conversion gain attains the optimum balance between low-light image quality and high dynamic range (HDR). This allows smartphone OEMs to optimize HDR performance for contrasting light and dark areas in any scene. The image sensor also utilizes 16-cell binning to achieve premium video capture of 12.5MP/4K at 120 frames per second (fps). It achieves 12.5MP/4K at 60fps with 2-exposure staggered HDR timing; an on-chip remosaic function enables 8K video and 2X crop zoom (with HDR) at 12.5MP.
The OVB0A image sensor supports CPHY, DPHY, and dual DOVDD (1.8 V and 1.2 V). Samples will be available in Q4 2022.
