PHOENIX, Oct. 20, 2015 — A 2.3-MP CMOS image sensor from On Semiconductor is intended for use in advanced driver-assistance systems.
Patent-pending LED flicker mitigation technology eliminates high-frequency LED flicker from traffic signs and vehicle LED lighting, and allows traffic sign-reading algorithms to operate in all light conditions.
The AR0231AT has a 1/2.7-in. optical format and a 1928 × 1208 active pixel array. It uses 3-μm back-side illuminated pixels with the company's DR-Pix technology, which offers dual conversion gain for improved performance under all lighting conditions.
The device captures more than 120 dB of dynamic range at 1080p resolution. It is capable of multicamera synchronization support to ease implementation in vehicle applications with multiple sensor nodes, and user programmability is achieved via two-wire serial interface.
