Automotive image signal processor simplifies SVS camera design

By Gina Roos, editor-in-chief

OmniVision Technologies, Inc. announced at AutoSens in Detroit  the OAX4010 automotive image signal processor (ISP) featuring the new high-dynamic-range (HDR) and LED flicker mitigation (LFM) Engine (HALE) combination algorithm for automotive viewing systems. When used with OmniVision’s OX01A10  and OX02A10  LFM image sensors, the OAX4010 enables more intelligent decision making by providing the LFM and HDR simultaneously, while operating over the automotive temperature range. The devices also offer the smallest-possible camera footprint.

Another key feature: The OAX4010 can process the images from one camera at 60 fps or two cameras at 30 fps, which reduces the number of ISPs required for surround-view system (SVS) cameras by 50%. Applications include rearview cameras, e-mirrors, and SVS.

Previously, designers had to choose between optimizing flicker mitigation or dynamic range, especially at temperatures above 80°C, said OmniVision, but now the OAX4010, in combination with its advanced ASIL features, can provide additional bright and dark scene details while eliminating LED flicker, which increases safety.

The OAX4010 also improves automotive imaging applications such as e-mirrors that often have to run in extreme temperature environments thanks to its capability to provide LFM and HDR at high temps and emerging AR camera systems, enabling the overlay of real-time images on GPS navigation displays, which requires flicker-free LED traffic signs and signals.

The ISP is pin-to-pin−compatible with OmniVision’s previous-generation ISPs, providing an easy migration path. It also allows Tier One automotive manufacturers to design one camera that can be used in both SVS and e-mirrors for greater economies of scale.

The OAX4010 is AEC-Q100 Grade 2- and ASPICE CL-2−certified for automotive applications. Samples are available now.
