The OX08D30 targets ADAS and autonomous-driving exterior cameras with improved HDR, lower power consumption and compact packaging.
OMNIVISION has introduced a new 8-megapixel CMOS image sensor designed for exterior automotive cameras used in advanced driver assistance systems (ADAS) and autonomous-driving applications.
The OX08D30 uses the company’s TheiaCel technology to address LED flicker and other temporal imaging artifacts that can affect cameras operating under changing lighting conditions. The sensor is pin-to-pin compatible with OMNIVISION’s OX08D10, which the company says is widely used across ADAS platforms.
TheiaCel Technology Targets LED Flicker
LED traffic lights and illuminated road signs can create flickering or distorted images when captured by automotive cameras because LEDs can switch rapidly relative to a camera’s exposure and readout.
The OX08D30 combines 2.1-micron TheiaCel technology with next-generation lateral overflow integration capacitors (LOFIC) and OMNIVISION’s DCG high-dynamic-range technology. The company said the combination is designed to mitigate LED flicker across lighting conditions while maintaining HDR image quality.
OMNIVISION claims the sensor can support enhanced detection ranges of up to 200 meters, along with improved low-light performance, high-temperature stability and color accuracy.
Lower Power, Smaller Package
The OX08D30 also targets size and power constraints in automotive camera systems.
According to OMNIVISION, the sensor consumes 20% less power and is 50% smaller than competing image sensors in its class. The device uses the company’s a-CSP package technology to reduce the overall footprint.
The sensor is intended for exterior automotive cameras, where image quality can be affected by direct sunlight, low-light conditions, temperature variations and artificial lighting.
OMNIVISION said the upgraded TheiaCel implementation uses a higher-density LOFIC structure to capture more photons and brighter LED signals, supporting its LED flicker mitigation capabilities.
Samples Available, Mass Production Underway
Paul Wu, director of automotive product marketing at OMNIVISION, said the OX08D30 was developed to improve low-light performance while maintaining stability at high temperatures and across different colors and lighting conditions.
Samples of the OX08D30 are currently available, and the sensor has already entered mass production, according to the company.
