Image sensor with stacked die tech brings 4K performance
OmniVision Technologies has announced the OV64C, its first 64 megapixel (MP) image sensor featuring a 0.8 micron pixel size to enable high resolution smartphone cameras in a 1/1.7" optical format. Built on OmniVision’s PureCel Plus stacked die technology, this sensor provides leading edge still image capture and exceptional 4K video performance with electronic image stabilisation (EIS) for high end smartphones.
The OV64C also offers a wide range of features, such as four-cell remosaic for full resolution Bayer output as well as digital crop zoom, and a CPHY interface for greater throughput using fewer pins, making it ideal for the main rear-facing camera in multicamera configurations.
“TSR estimates there will be 127 million image sensors with 64 MP or higher resolution shipped to smartphone manufacturers in 2020,” said Arun Jayaseelan, Staff Marketing Manager at OmniVision. “The OV64C, with its premium resolution and features, is well positioned to address this ramp in demand among high end smartphone designers.”
The OV64C integrates an on-chip four-cell colour filter array and hardware re-mosaic, which provides high quality, 64 MP Bayer output in real time. In low light conditions, this sensor can use near-pixel binning to output a 16 MP image with four times the sensitivity, offering 1.6 micron equivalent performance for previews and still captures. In either case, the OV64C can consistently capture the best quality images, as well as enabling two times digital crop zoom with 16 MP resolution and fast mode switch.
The sensor features type-2, two by two microlens phase detection autofocus (ML-PDAF) to boost autofocus accuracy, especially in low light. Output formats include 64 MP at 15 frames per second (fps), 8K video at 30 fps, 16 MP captures with four-cell binning at 30 fps, 4K video at 60 fps and 4K video with EIS at 30 fps. Additionally, the OV64C supports three-exposure, staggered HDR timing for up to 16 MP video modes.
Samples of the OV64C image sensor are available now.
