powerful electronic distortion correction for automotive vision systems OV480 companion processor product brief lead free available in a lead-free package omnivision's OV480 is a low-cost companion processor designed to enhance camera performance in wide field-of-view (fov) automotive vision systems. the OV480 works with omnivision's high-performance autovision image sensors up to megapixel resolution to deliver best-in-class electronic distortion correction and enhanced low-light performance. due to the processor's ability to correct lens distortion up to 195-degrees, the OV480 allows a single camera to be used across multiple vehicle platforms. the OV480's low-light performance enhancement and temporal noise filter significantly enhances nighttime user experience. the highly compact asic processor also provides top down and perspective views, which offers clear imaging for specific rear-view driving functions such as trailer ball hitching. additionally, the OV480 has a cross traffic view feature, allowing drivers to see around side obstacles. the compact yet powerful OV480 companion processor also supports user-defined hot pixel correction, rotation correction, and up to 4x zoom with smooth transition options. find out more at www.ovt.com.
