Industry-Leading Distortion and Perspective Correction for Backup Camera Automotive Imaging Systems
OMNIVISION’s OV494 is a compact image signal processor (ISP) that enables best-in-class electronic distortion and perspective correction for a wide range of rear view camera architectures in automotive applications. The OV494 can output on a wide range of interfaces including DVP, MIPI, BT1120 or NTSC, performing distortion correction on high-quality video with up to 190 degrees of pixel-mapping flexibility. The OV494 also offers eight independent overlays with a 32‑color palette for each image, without requiring additional processing support.
The OV494 is ideally suited to work with OMNIVISION’s portfolio of high-performance image sensors, including the OV9716 and OV10640 automotive image sensors. The OV494 can process image and video input of up to 1.4‑megapixels at 60 frames per second (fps), with support for high dynamic range (HDR) up to 120 dB.
The OV494 comes in a compact 7 mm x 7 mm, 169‑pin ball grid array (BGA) package.
