Aurora

The "Real-Time" SD, HD and 2K data* Grain and Noise management system uses a non-recursive filter to reduce or remove film grain and video noise without the smearing and artifacts often associated with this process. Five frames of internal memory allow Aurora's Finite Impulse Response filter (FIR) to average pixel values over as many as six frames where little motion exists. Fewer frames of history are used with moving objects to minimize motion artifacts. Removal "Amount" and "Threshold" controls combined with a unique still motion monitor process allows the Aurora™ user to set precise amounts of grain reduction on a frozen frame. Image enhancement with coring provides image sharpening without enhancing the grain. Aurora's "Gore Filter" has seven different frequency characteristics that provide filtering to lower peak to peak transients, such as grain, while allowing larger transitions to pass unaffected.
