OmniVision launches automotive SoC for entry-level rearview cameras
OmniVision Technologies, Inc. announced its 1.3MP OX01E10 SoC, providing automotive designers with what it says is "the industry’s best imaging performance for entry-level rearview cameras (RVC) across a wide range of challenging lighting conditions, along with the most compact form factor and lowest power consumption." The OX01E10 integrates a 3-micron image sensor and an advanced image signal processor (ISP) in a single, 0.25 in optical format package. According to the company, this enables designers to achieve a small form factor with excellent low-light performance, ultra-low power, and reduced cost while improving reliability by using only one printed circuit board (PCB). Additionally, it provides two onscreen display overlay layers for driver guidelines, as well as distortion correction to straighten any curved edges from lenses with a wide viewing angle.
“RVC remains the largest volume application in the automotive camera market,” said Andy Hanvey, Director of Automotive Marketing at OmniVision. “Our OX01E10 SoC provides the best option for automotive designers responding to the growing consumer demand for better RVCs. Additionally, this SoC’s functional safety features allow module providers to create a single platform for both the viewing cameras and the machine vision applications that require ASIL B, while offering pin-to-pin compatibility and design reuse with our OX01F10 SoC for surround view systems (SVS).”
According to the company, the new SoC features power consumption that is over 35% lower than competitors’ and significantly reduces temperature. The company also says that this is the only imaging device for entry-level RVC that does not require a metal heat sink, allowing for the use of plastic camera module bodies to reduce costs. With its compact package size, it also enables smaller cameras that can fit in tighter spaces. In addition, by integrating both the image sensor and ISP into a single chip, designers can save on both cost and space by eliminating the second PCB in typical two-chip implementations.
The company’s dual conversion gain (DCG) technology is employed in this SoC to achieve a high dynamic range (HDR) of 120 dB with only two captures, as opposed to three (which the company says is required by the competition), which minimizes motion artifacts while reducing power consumption and boosting low-light performance. Its integrated ISP further enables great image quality with a number of features, such as lens chromatic aberration correction, advanced noise reduction, and local tone mapping.
The OX01E10’s image sensor is built on the PureCel Plus pixel architecture, which is renowned for its low-light sensitivity and provides the industry’s best SNR performance, according to the company. As a result, it performs well in challenging lighting conditions, eliminating unnatural halos from LEDs and providing contrast on bright days.
This SoC provides 1.3 MP resolution and a 1340 x 1020 array size at 30 fps. It also enables output flexibility with both 2-lane MIPI and 10-bit DVP interfaces. It is AEC-Q100 Grade 2 certified and samples are available now, with mass production expected in Q3 2020.
