Melexis Microelectronic Systems have developed a CMOS image sensor, MLX75307, for automotive active safety applications. The front-vision applications for which the sensor will be used include high-beam assist and night vision.
The sensor, built to the EMVA1288 standard, helps to produce brighter images even in low-light conditions, thereby alerting the driver of impending hazards. The MLX75307 detects near infrared (NIR) light irradiance below 500 photons per pixel at a frame rate of 150 fps. Production is scheduled to begin in 2009.
Exterior view applications using the 750×400 pixels sensor include night vision, adaptive cruise control, lane departure warning and traffic sign recognition. The sensor will also assist in interior view applications such as driver drowsiness and smart airbag deployment.
Globally, demand for active safety features in a vehicle is expected to grow in the future. Melexis is one of the key players in the vision-based safety applications segment. With the introduction of the new sensor, the company is increasing their presence in the safety systems applications.
