Time Filter
An in-camera liquid crystal shutter that changed how motion is captured.
Motion picture cameras have a problem with time. When panning, the background judders. Wheels appear to spin backwards, picket fences and brick walls jump across the screen, and helicopter blades look, well, just wrong. For a century, it’s just been accepted that motion imaging would simply do these things, and there was nothing that could be done to fix it.
Tessive’s answer was the Time Filter: a global liquid crystal shutter placed in front of the lens and synchronized with frame acquisition. It dramatically changed the look and feel of motion in-camera, recording the natural fluidity of the real world without loss of sharpness.
Especially useful for
- Fixing judder in pans
- Correcting repeating motion such as wheels, fences, and aircraft propellers
- Eliminating flicker from lighting, regardless of frame rate or line frequency
- Virtually eliminating flicker on plasma or CRT displays
- Reducing striping or tearing artifacts from uncontrolled strobes and flashes
- Rendering human movement more accurately and flowingly
