OmniVision Technologies, which develops advanced digital imaging solutions, announced the OX03F10 automotive image sensor, which adds higher 3MP resolution and cybersecurity features as vehicle designers transition from Level 2 and 3 advanced driver assistance systems to higher levels of autonomy.
The new sensor expands on OmniVision’s ASIL-C viewing camera family, maintaining a combination of a 3.0-micron pixel size with a high dynamic range (HDR) of 140dB and LED flicker mitigation (LFM) performance for minimized motion artifacts. The sensor is offered in a 1/2.44-inch optical format, featuring a four-lane MIPI CSI-2 interface.
OmniVision says it is the first image sensor with HDR and LFM that can deliver a wide vertical array resolution of 1920 x 1536p at the highest rate of 60 frames per second. This gives higher image quality for feeding surround view systems (SVS) captures into autonomous, machine-vision systems, the company said. The wider vertical array is also important for e-mirror applications, giving wider coverage and eliminating blind spots.
“In addition to excellent image quality across all lighting conditions, higher resolution and cybersecurity are becoming must-haves for the designers of viewing cameras – particularly for SVS,” said Kavitha Ramane, staff automotive product marketing manager at OmniVision. “Our new OX03F10 maintains OmniVision’s unique combination of the industry’s top HDR and LFM capabilities over the entire automotive temperature range, along with ASIL-C functional safety and the best low light performance, while adding the 3MP resolution and cybersecurity features that are required as designers begin to integrate viewing cameras into autonomous vehicle systems.”
THe OX03F10 also maintains a small package size and low power consumption, which lets designers place cameras that continuously run at 60 fps even in the highest spaces, OmniVision adds. It also retains the family’s basic image processing capabilities, including defect pixel correction and lens correction. In addition, the integrated HALE (HDR and LFM engine) combination algorithm can simultaneously provide top HDR and LFM performance, resulting in high image quality for automotive viewing applications – including SVS, rearview cameras (RVC), and e-mirror camera monitoring systems (CMS) – across lighting conditions and in the presence of flickering LEDs from headlights, road signs, and traffic signals.
Additional features include:
- Deep Well, a dual conversion gain technology that enables the OX03F10 to capture lower motion artifacts than competing sensors that offer 140dB HDR.
- Split-pixel LFM technology with four captures that offer consistent performance over the entire automotive temperature range.
- PureCel Plus-S stacked architecture, which provides pixel performance advantages over nonstacked technology. This allows the company to boost pixel and dark current performance, resulting in performance improvements over the prior generation of its viewing camera sensors.
The new OX03F10 image sensor is now available for limited sampling in a-CSP and a-BGA packages. OmniVision says it is planned to be AEC-Q100 Grade 2 certified. More details are available through OmniVision sales channels.
