HDR image sensors aim to make cars safer

Hyperlux image sensors from onsemi deliver a 150-dB high dynamic range (HDR) with LED flicker mitigation (LFM) across the full automotive temperature range. Targeting advanced driver assistance systems (ADAS), Hyperlux sensors are also expected to provide a smooth transition to Level 2+ driving automation, which requires the driver to only take over when alerted by the technology.

Hyperlux CMOS digital image sensors feature a 2.1-µm pixel size and serve both sensing and viewing camera applications. The first two devices in the Hyperlux family are the AR0823AT and AR0341AT. The AR0823AT is an 8.3-Mpixel, 1/1.8-in. sensor, while the AR0341AT is a 3-Mpixel sensor in a 1/3.6-in. format.

The simultaneous HDR and LFM capabilities of these devices enable them to capture high-quality images under extreme lighting conditions without sacrificing lowlight sensitivity. LFM also ensures that pulsed light sources do not appear to flicker, avoiding flicker-induced machine vision issues. Further, onsemi claims that the automotive image sensors consume up to 30% less power and occupy up to a 28% smaller footprint that competing devices.

The AR0823AT and AR0341AT are now sampling to early access customers. Learn more about Hyperlux technology here.
