Rugged COTS LCD with built-in image algorithms
Z Microsystems, Inc.: Ground Control Station (GCS) display panel
Sure, "anyone" can ruggedize an LCD to make it withstand extreme temperatures, shock, vibration, salt spray, and humidity in explosion environments. We're kidding, of course. Ruggedizing an LCD while also making it sunlight readable is no small feat. That's why Z Microsystems' Ground Control Station (GCS) display panel with Real-Time Enhanced Video (RTEV) is so darned compelling. It is designed for the harshest military applications, and it has built-in image enhancement electronics. Designed for live video surveillance feeds such as those from UAVs or other sensors, the RTEV guts are based upon FPGA algorithms performing signal processing.
Two primary modes include image enhancement and edge detection algorithms, both of which add minimal latency for real-time operations. Functions include: contrast enhancement during changing brightness and contrast situations; dusk/dawn viewing; "de-hazing" to enhance image readability in fog and sand storm environments; and edge detection to identify anomalous shapes while highlighting details. A Picture-In-Picture (PIP) feed in RGB or NTSC can be scaled or blended into the primary image, and all GCS panel functions can be toggled on or off locally or remotely. This third-generation GCS has updated electronics and is designed for LCD tech refresh, meaning that the internal LCD can be swapped out when newer panels come along.
