BRUSSELS, Belgium – September 19, 2023 – OMNIVISION debuted its OX08D10 8-megapixel (MP) CMOS image sensor with TheiaCel™ technology. The OX08D10 features lowlight performance. It also has low power consumption in a compact size. It is the first image sensor that features OMNIVISION’s new 2.1-micron (µm) TheiaCel™ technology.
TheiaCel™ technology harnesses the capabilities of next-generation lateral overflow integration capacitors (LOFIC) and OMNIVISION’s DCG™ high dynamic range (HDR) technology. It eliminates LED flicker regardless of lighting conditions. TheiaCel™ enables the OX08D10 to achieve HDR image capture at up to 200 meters. This range is the sweet spot for delivering the best balance between SNR1 and dynamic range. It is optimal for automotive exterior camera applications.
The new solution enhances automotive safety by providing enhanced resolution and image quality in exterior cameras. Moreover, this benefits advanced driver assistance systems(ADAS) and autonomous driving (AD).
“The new OX08D10 image sensor offers automotive OEMs a single device that integrates essential features. These features encompass low-light performance, LED flicker mitigation (LFM), compact size, and low power consumption. Additionally, this eliminates the necessity for customers to make performance or design sacrifices to combat LED flicker, as they have done in the past,” said Paul Wu, automotive product marketing manager, OMNIVISION. “Additionally, we are excited to debut our new TheiaCel™ technology at AutoSens this year. Moreover, TheiaCel™ brings a new era to single-exposure HDR in an easy-to-implement solution that yields dramatic improvements in image quality.”
“LFM, HDR and high resolution have become essential prerequisites in modern automotive image sensors to achieve higher autonomy vehicles,” said Anas Chalak, technology & market analyst, Imaging at Yole Intelligence, part of Yole Group. “OMNIVISION’s TheiaCel™ DCG + LOFIC solution fulfills these criteria. It aligns with the trend of implementing more exterior cameras per car in the upcoming years. By 2028, we expect the ADAS camera market volume to reach around 105M units. The overall automotive image sensor market is projected to expand to $3.7 billion during this time, experiencing a CAGR22-28 of 8.7%.”
In the automotive market, flicker from LED traffic lights poses a serious challenge for imaging solutions. This prevents ADAS and AD systems from correctly detecting lighted traffic signs. The industry has been clamoring for a solution that could be easily integrated into a CMOS image sensorto meet this challenge. Some previous approaches, while achieving satisfactory LFM, have resulted in reduced image quality, especially at high automotive temperatures.
OMNIVISION’s new 2.1µm single-pixel TheiaCel™ technology delivers high LFM without sacrificing image quality. TheiaCel™ leverages next-generation LOFIC capabilities. It also utilizes the proven strength of OMNIVISION’s proprietary HDR technology, which includes patented DCG and split-diode technology. This technology captures extremely high-contrast scenes for optimum content and image quality. OMNIVISION’s TheiaCel™ DCG + LOFIC solution achieves a wider dynamic range than earlier single-exposure HDR architectures.
The new OX08D10 achieves overall superior performance in key areas compared to its non-LOFIC-based predecessor – in particular, its LFM dynamic range is 3.3x higher and total dynamic range nearly 3x higher. It features upgraded cybersecurity to comply with the newest MIPI CSE version 2.0 standards, which adds functional safety to automotive image sensor data streams. Furthermore, the TheiaCel™device features OMNIVISION’s a-CSP™ package technology for the smallest possible solution. Samples are available now, and the OX08D10 will be in mass production in the second half of 2024.
