OMNIVISION’s OV32B is a 32MP, 0.7 micron pixel image sensor with a 1/3” optical format that enables smartphone designers to offer the highest possible front-facing camera resolution in the limited space available. The OV32B supports 2- and 3-exposure HDR timing for up to 8MP video modes and still previews. Additionally, it integrates a 4‑cell color filter array and on-chip hardware re-mosaic, which provides high quality, 32MP Bayer output in real time—a feature that normally would be difficult to achieve in the 1/3” optical format.
The OV32B is built on OMNIVISION’s PureCel®Plus stacked die technology, providing leading-edge still image captures and exceptional 1080p video recordings at 180 frames per second (fps). In low light conditions, this sensor can use near-pixel binning to output an 8MP image with 4x the sensitivity, offering 1.4 micron pixel equivalent performance for previews and still captures. The OV32B can also consistently capture the best quality images while enabling seamless fast mode switch and multicamera sync. In addition to front-facing cameras, these features are also ideal for rear-facing telephoto smartphone cameras.
To boost autofocus accuracy, especially in low light, the OV32B offers the option to integrate type‑2, 2×2 microlens phase detection autofocus (ML-PDAF). It also provides a CPHY interface for greater throughput using fewer pins, as well as a DPHY interface. Output formats include 32MP at 15 fps, 8MP at 60 fps and 6MP (16:9) at 90 fps—all with 4‑cell binning. Additionally, the sensor can output 1080p video at 120 fps, 1.5MP captures (16:9) at 240 fps and 720p video at 360 fps.
