High Frame Rate 4-Megapixel Sensor with Excellent
Low-Light Sensitivity and OmniHDR-F™ Technology
for Security Applications
The OV4685 is a high performance 4-megapixel
CameraChip™ sensor in a native high definition (HD)
16:9 format designed for next-generation surveillance
and security systems. The sensor is built on a 2-micron
OmniBSI-2™ pixel that provides best-in-class sensitivity,
and uses advanced OmniHDR-F™ technology to provide
industry leading staggered high dynamic range (HDR).
The 1/3-inch OV4685 can capture full-resolution
4-megapixel HD video at 90 frames per second (fps),
1080p HD at 120 fps, and binned 720p HD at 180 fps.
The sensor's high frame rates enable crisp, clean image
and video capture of fast moving objects.
The OV4685's advanced OmniHDR-F technology provides
staggered HDR timing, increasing dynamic range to
100 dB while recording high-quality images and video
under extreme variations of bright and dark conditions.
The sensor features a high-speed 4-lane MIPI serial
output interface to facilitate the required high data
transfer rate. The OV4685 is available in a chip scale
package (CSP).
