2015 Electrosonic Open Day

GBvi will be at the UK HQ of Electrosonic in Dartford on the 9th and 10th of September for their annual technology open event.

It’s shaping up to be an exciting event, with many new technology demos and workshops scheduled.

The Importance of Optical Blending

Video projectors have limited sequential contrast. This means that, in dark scenes, background leakage light is always visible.

When multiple projectors are overlapped and electronically blended to form a larger image, there will be unwanted double-intensity background leakage. This becomes most apparent when dark-scenes are projected.

The image is an exaggerated example, showing how ‘leakage’ black levels cause unwanted bright-ups in the overlap zones, and the importance of optical blending.
