Omnivision adds 5-MP image sensor with TheiaCel tech

Omnivision has introduced the new OX05D10 5-megapixel (MP) CMOS image sensor with TheiaCel technology, providing high LED flicker mitigation (LFM) without sacrificing image quality. The OX05D10 image sensor targets automotive use cases where high dynamic range (HDR), low-light performance and LFM are critical.

The OX05D10 5-MP image sensor joins the previously announced OX08D10 8-MP automotive CMOS image sensor with TheiaCel technology. It retains all the same key features that automotive designers require, including small size, low power and low-light performance.

The 2.1-µm single-pixel TheiaCel technology addresses automotive applications such as advanced driver assistance systems (ADAS) and autonomous driving (AD) that require improved LFM, HDR and high-resolution image sensors. It can mitigate LED flicker regardless of lighting condition.

Delivering improvements in HDR, the TheiaCel technology leverages next-generation lateral overflow integration capacitor (LOFIC) capabilities in combination with Omnivision’s other proprietary HDR technologies, including its patented dual conversion gain (DCG) technology, to capture extremely high-contrast scenes for optimized content and image quality.

Together, the TheiaCel DCG + LOFIC solution delivers a wide dynamic range within a single-exposure HDR image. One application example cited is the pulsed illumination from LED traffic lights, which poses a challenge for many imaging solutions, preventing ADAS and AD systems from correctly detecting lighted traffic signs.

The 5-MP sensor also leverages Omnivision’s PureCel Plus-S technology, known for its low-light sensitivity and signal-to-noise ratio performance. Key features include 140-dB dynamic range (using VS exposure for dynamic range extension), >110 dB LFM and motion free dynamic range (using single exposure HDR with DCG + LOFIC), support for 4-lane MIPI CSI-2 and cybersecurity to prevent camera/host interface hacking. The sensor is housed in an a-CSP package for the smallest size possible.

Samples of the OX05D10 are available now. Mass production will be available in the third quarter of 2025. The OX05D10 will be showcased at AutoSens Detroit, May 21-23, 2024, in Detroit, at Omnivision’s Booth 207.
