OmniVision Technologies’s OAX4010 automotive image signal processor (ISP) comes with the company’s new High Dynamic Range (HDR) and LED flicker mitigation (LFM) Engine (HALE) combination algorithm.

In tandem with OmniVision’s widely deployed OX01A10 and OX02A10 LFM image sensors, the OAX4010 enables more intelligent decision-making over the automotive temperature range. The OAX4010 can process the images from one camera at 60fps or two cameras at 30fps, which reduces the number of ISPs required for surround-view system (SVS) cameras by 50%.

Previously, designers using competitive devices had to choose between optimizing flicker mitigation or dynamic range, especially at temperatures above 80ºC. With the OAX4010, in combination with its advanced ASIL features, designers can provide drivers with additional bright and dark scene details while eliminating LED flicker, thus increasing safety. Use cases include rear-view cameras, e-mirrors and SVS. The OAX4010 also enables the emerging AR camera systems to overlay real-time images on GPS navigation displays, which requires LED traffic signs and signals to be flicker-free. OAX4010 samples are available now, and it is AEC-Q100 Grade 2 certified and ASPICE CL-2 for automotive applications.
