Sony IMX485 12MP COMS Camera Image Sensor

Sony IMX458 (12MP) is a camera image sensor for smartphones, it has been widely used in many famous smartphones. Now Sony IMX458 adopts a new PLCC package design to fit the SoC of Hi3559V100. In addition to 4k30fps resolution, the action camera solution also supports slow motion (or high frame rate) shooting mode, it can shoot 1080p HD video at up to 60 frames per second. HiSilicon Hi3559V100 provides advanced H.265 image/frame compression technology to support 4K/30fps video encoding. By utilizing Linux and HiSilicon Lite OS dual-core operating systems, this action camera can boot up super fast and provide the most advanced data processing capabilities because it has built-in 17 1.25GHz and 7 800MHz dual-core processors.

Sony IMX485 is a 1/1.2 type 4K resolution back-illuminated CMOS image sensor. The ample pixel size of 2.9 microns squared, coupled with the latest pixel technology for low noise functionality, improves low-light performance, making this sensor ideal for high-end 4K security cameras. This image sensor is ideal for security cameras in a variety of surveillance applications, such as anti-theft, disaster alarms, traffic monitoring systems or commercial complexes.
