IGLOO视频演示板

IGLOO Video Demo Kit: A Plug-and-Play DemonstraTIon Platform

The IGLOO Video Demo Kit consists of an IGLOO video demo board and your choice of an LCD adapter board. You can choose from two plug-and-play display adapter boards mounted with different LCDs, ranging from 5.5" to 7", and resoluTIons from QVGA (320x240) to SVGA (800x480). You can also build your own customized LCD adapter board. The IGLOO video demo board has an IGLOO device that interfaces with several video/image sources, such as a digital visual interface (DVI) input and a CMOS sensor interface. In addiTIon, off-chip memory is provided for data buffer and storage.
