High Performance Image Signal Processor
Companion Chip for Automotive Imaging
OmniVision's OV495 is an image signal processor (ISP)
companion chip that pairs with OmniVision's family of
automotive RAW image sensors for advanced
automotive imaging applications. The OV495 enables
electronic distortion and perspective correction without
video compression artifacts, making it an ideal ISP
solution for next generation rear view camera and
camera monitor system (CMS) applications. The OV495
is compatible with OmniVision's OV2775, OV10650, and
OV10640 automotive image sensors.
The OV495 can process video streams of up to two
megapixels in resolution at a maximum of 60 frames per
second (fps), with distortion and perspective correction
to enable different viewing modes and angles. The
OV495 also supports overlay capability for features,
such as parking guidance, to enable high-performance
vision systems.
The OV495 comes in an AEC-Q100 Grade 2-qualified
7 x 7 mm BGA package and contains an advanced set of
safety mechanisms to enable ASIL rated camera
systems.
