Automotive camera SoC combines low-light performance, lowest power and smallest size
In a single, 1/4″ optical format package, the OX01F10 integrates a 3.0 micron image sensor and an advanced image signal processor (ISP), solving the automotive rear view camera (RVC) and surround view system (SVS) challenges of achieving 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).
OmniVision’s dual conversion gain (DCG) technology is employed in this SoC to achieve a high dynamic range of 120dB with only two captures, as opposed to three required by the competition, which minimizes motion artifacts while reducing power consumption and boosting low-light performance. Its integrated ISP further enables superior image quality with a number of advanced features, such as lens chromatic aberration correction, advanced noise reduction, and optimizations for the on-chip image sensor’s PureCelPlus technology.
The PureCel Plus technology has a low-light sensitivity, providing an industry best SNR1 of 0.19 lux. This results in the OX01F10 performing better than the competition across challenging lighting conditions, enabling the ability to eliminate unnatural halos from LEDs and to provide better contrast on bright days.
The OX01F10 features <300mW typical power consumption, 30% lower than competitors and significantly reduces temperature. According to Omnivsion this is the only imaging device today that does not require a metal heat sink, allowing for the use of plastic camera module bodies to reduce costs. Its compact package size also enables smaller cameras that 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.
This SoC provides 1.3MP resolution and a 1340×1020 array size at 30 fps, which offers ample resolution for calibration. It also enables output flexibility with both 2-lane MIPI and 10-bit DVP interfaces.
Analysts predict that SVS and RVC will continue to hold the majority share in the automotive camera market, with over 50% of the total market volume through 2023. SVS, in particular, is expected to double its growth between now and 2023 due to increased customer adoption.
