BEIJING, China. – November 8, 2016 – OMNIVISION Technologies, Inc., a leading developer of advanced digital imaging solutions, today announced the OV20880 and OV20880-4C, a new family of 20-megapixel PureCel®Plus-S stacked-die sensors. Built on OMNIVISION’s second-generation PureCel Plus technology 1.0-micron pixel technology, the OV20880 and OV20880-4C capture stunning, high-resolution images and bring a host of advanced features to rear- and front-facing camera applications.
OMNIVISION’s PureCel Plus-S second-generation 1.0-micron pixel boasts enhancements to deep trench isolation (DTI) and buried color filter array (BCFA) process technologies, enabling the OV20880 and OV20880-4C to deliver high-quality pictures. The sensors’ compact form factor, power efficiency, and industry-leading image quality make them an excellent fit for slim, high-end smartphones.
The OV20880, designed specifically for main camera applications, offers advanced capabilities such as zig-zag high dynamic range (zHDR) and phase detection autofocus (PDAF). zHDR uses a long and a short exposure in a single frame to extend the dynamic range capabilities of the sensors. Long and short exposure lines are diagonally interlaced across the entire pixel array in a zig-zag pattern. This enables live preview and video recording in HDR mode and single-shot full-resolution HDR images in capture mode without shutter lag.
The OV20880 is also optimized for mobile dual-camera zoom solutions, offering several dual-camera-friendly features such as context switching, scalar, and electronic image stabilization (EIS). The on-chip EIS can synchronize with a gyro sensor on-board without latency, enabling advanced capabilities such as image deblur.
“One of the perpetual challenges in digital imaging is shrinking pixels without sacrificing critical image-quality attributes such as low-light performance, dynamic range, and color reproduction,” said James Liu, senior technical marketing manager at OMNIVISION. “The second-generation 1.0-micron PureCel Plus-S pixel used in the OV20880 series marks another bold step toward putting professional-grade image quality and advanced features into smartphone cameras.”
The OV20880-4C’s unique color filter pattern offers OMNIVISION’s customers a variety of output modes depending on the use case. The on-chip in-pixel binning feature allows up to four times more light photons than a regular 1.0-micron pixel. This creates high-sensitivity, high-quality images even in low-light conditions, and allows end users to take clear “super selfies” in a wide range of lighting environments. The OV20880-4C also pairs well with OMNIVISION’s complete software solution for resolution recovery that enables high-resolution 20-megapixel selfies when combined with the sensor’s 4-cell mode.
“Smartphone users are relying more and more on front-facing cameras to shoot high-quality selfies in a wide variety of environments and lighting conditions,” said Arun Jayaseelan, senior product marketing manager at OMNIVISION. “The OV20880-4C can help deliver great selfies even in dark environments, without compromising resolution.”
Both the OV20880 and OV20880-4C feature a C-PHY interface that enables power savings and pin count reduction. The OV20880 and OV20880-4C can fit into industry-standard, slim form factor modules and integrate well with slim handsets while packing impressive feature sets and 20-megapixel resolution.
The OV20880 and OV20880-4C are currently available for sampling and are expected to enter volume production in the first quarter of 2017.
