OX03F10

LED flicker mitigation (LFM) is a technology that eliminates the flickering effect when capturing LED traffic lights and signs. Standard cameras capture images at specific intervals, and if the LED pulse frequency doesn't match the camera timing, the LED appears to flicker or may be completely missed in some frames. This is dangerous for ADAS systems that rely on traffic sign recognition. LFM technology uses extended exposure timing to capture the complete LED pulse cycle, ensuring consistent visibility. The OX03F10's LFM handles pulse frequencies from 90Hz to over 2kHz, covering all common LED types.

For any automotive camera application involving traffic sign recognition, LFM is essential. Contact us for LFM implementation guidelines.

The OX03F10 supports ASIL-B functional safety level according to ISO 26262. Safety features include: comprehensive built-in self-test (BIST) for sensor diagnostics; CRC protection for register settings and output data; temperature monitoring with alarm thresholds; and output data tagging for frame identification. The sensor provides diagnostic information through dedicated registers that can be monitored by the system safety monitor. These features enable the sensor to be used in safety-critical applications like automatic emergency braking and lane departure warning systems.

For ASIL-B applications, implement all recommended safety mechanisms. Contact our automotive team for functional safety documentation.

The OX03F10 is qualified to AEC-Q100 Grade 2, supporting operating temperatures from -40°C to +105°C. This wide temperature range is essential for automotive applications where cameras are mounted outside the vehicle and exposed to extreme environmental conditions. The sensor maintains consistent image quality across the entire temperature range through built-in temperature compensation. Dark current performance is optimized for high-temperature operation common in engine compartment or roof-mounted camera locations. The package is designed for automotive reliability requirements including thermal cycling and mechanical stress.

For Grade 2 applications, ensure proper thermal management in your camera module design. Contact us for thermal design guidelines.

The OX03F10 supports multiple HDR modes: 120dB HDR using staggered exposure for most applications; 140dB ultra-high dynamic range mode for extreme contrast scenes; and split-pixel HDR using dual-diode technology for motion artifact reduction. The HDR modes can be combined with LED flicker mitigation for challenging automotive lighting conditions. The sensor supports both line-interleaved HDR output for real-time processing and frame-sequential HDR for maximum dynamic range. HDR can be enabled for both video streaming and single-frame capture modes.

Select HDR mode based on your scene contrast requirements. 120dB mode is suitable for most applications. Contact us for HDR tuning recommendations.

The OX03F10 uses automotive-grade CSP packaging compatible with standard M12 lens mounts. For surround view applications, 190-degree fisheye lenses are typically used to provide 360-degree coverage with four cameras. For ADAS front cameras, lenses with 50-60 degree horizontal FOV are common. The 1/2.44-inch optical format requires lenses designed for 1/2.5-inch or larger sensors. Automotive lenses must meet strict reliability requirements including vibration resistance, thermal stability, and IP67 sealing. Will Semiconductor works with qualified automotive lens suppliers including Sunny Optical and Sekonix.
