OmniVision Connects Image Sensor and Processor in a Single Package for Automotive Viewing Cameras

Posted Jan 08, 2018 by OmniVision Technologies

OmniVision has connected its high-performance color CMOS image sensor, OX01B40, and an image-sensor processor (ISP) in a single 8.5 x 8.5 mm package. The OX01B40 system-in-package (SiP) can deliver 120 dB high dynamic range, and is designed specifically for automotive viewing cameras, enabling smaller and simpler camera designs for improved styling. 

Many existing sensing solutions for viewing cameras can only support one type of interface, which requires developers to select a different sensor and design a new PCB when a different interface is required. The OX01B40, on the other hand, provides three options: digital video port (DVP), MIPI serial interface, and NTSC analog interface. This enables automotive Tier-1 and OEM engineers to create one design that addresses different applications, thus saving time and money.

Connecting the image sensor and ISP in a single package provides the smallest form factor for HD cameras today, enabling the design of an automotive viewing camera that consumers won't even notice. At the same time, we keep system costs down and reduce developers' engineering issues by supporting three different interfaces, including all the features their customers want to see in a single package.

The OX01B40 is built on OmniVision's 2.8-micron OmniBSI-2 Deep Well pixel technology. It delivers best-in-class low-light sensitivity and high dynamic range (HDR) performance, even in challenging lighting conditions. It also boasts 1392 x 976 resolution with a 2.8-micron pixel size, streaming at 30 frames per second (FPS) for MIPI or DVP interfaces, or 60 FPS for NTSC. Additional advanced features include:

  • 2.8-micron OmniBSI-2 Deep Well pixel, enabling best in class low light performance
  • Advanced HDR ISP, delivering high-quality images in challenging conditions
  • Local and global tone-mapping support
  • Distortion and perspective correction, which creates undistorted images at up to a 190-degree angle
  • Overlay feature that supports static and dynamic overlays of up to eight independent layers
  • Power consumption is very low, at below 400 mW, allowing efficient thermal management even though the ISP is stacked under the sensor. The OX01B40 is significantly more power-efficient than competing solutions from other manufacturers.

The OX01B40's features are optimized for all automotive viewing cameras, including HD rearview cameras and surround-view cameras. It is sampling now, with volume production expected in Q4 2018. This product will be demonstrated at OmniVision's CES 2018 private suite.
