Imaging Chip Lets Cars React To Trouble Ahead

摘要

Designed for advanced front-vision automotive apps, the MLX753O7 CMOS image sensor can dramatically improve road safety by rapidly providing the image data needed to proactively and automatically alert drivers to potential dangers. Evaluated using the new EMVA1288 standard for measuring imaging sensor performance, the sensor has been shown to detect, at 150-fps rates, near-IR light irradiance below 500 photons/pixel. This is like detecting a candle over 250 m away with a night-vision lens. The imager has the first high-dynamic-range matrix (750 × 400 pixels) able to extend both the input and output dynamic ranges, providing up to 128-dB dynamic response in a single frame. The sensor's low-light-response-boost capability can increase image brightness and contrast in low-light conditions-a specific concern for safety at night-and both capabilities can be combined in a single frame.
