~3D Depth-map Camera Controller-eSP870


Etron's eSP870 chipset is an innovative USB3.0 3D Depth-map Controller which enables gesture/skeleton control by stereoscopic camera. It delivers high performance depth-map, 3D video and 2D video for various applications. The depth information is sent to the host processor for further processing. eSP870 enables the 3 dimension sense ability for digital devices and empowers the hottest natural user interface in many different platforms.


eSP870 is equipped with sophisticated computational algorithms to retrieve the synchronized stereo video and generate a VGA size depth-map image. With the USB3.0 High Speed Interface, eSP870 can not only transfer depth-map images but high quality 3D or 2D instant video in the meantime. eSP870 has minimal CPU requirements as the heavy depth-map computing algorithms run on eSP870 itself ,thus reserving the critical CPU resource for the most exciting application.
