Denso says its image sensors provided by Sony Semiconductor Solutions has helped it improve the performance of its in-vehicle vision sensors and can now detect pedestrians during night conditions.

"Traffic accidents occurring at night often involve pedestrians and can cause severe injury," noted a Denso statement. "The New Car Assessment Programme (NCAP) followed in Europe and Japan, is considering including night-time pedestrians within the scope of collision avoidance in its safety performance evaluation standards for automatic braking systems.

"The newly developed vision sensors will help meet this new safety requirement."

Sony's image sensors, which are also used in surveillance and other monitoring devices, enable cameras to take clear images of objects even at night.

Denso maintains it has improved the quality of Sony's image sensors in terms of ease of installation, as well as heat and vibration resistance, to be used in vehicle-mounted vision sensors.

Denso has also used Sony's image signal processors (ISPs) for noise reduction and optimisation of camera exposure parameters to better recognise and take clearer images of pedestrians at night.

Sony holds the largest share of the global image sensor market. Its image sensors are used in a wide variety of products including digital cameras, smartphones and other home electronics.

Vision sensors are used with cameras to detect white lines on roads and objects ahead.
