摘要: A multi-purpose scaler utilizes a vertical module and moveable horizontal to resample video signal either vertically or horizontally according selected scaling ratio. The resides in one of two slots within the architecture provide reduction expansion as desired. is arranged scale using non-linear 3 zone both direction when selected. keystone correction height distortion presented through projector at non-zero tilt angle. also interlacing de-interlacing frames necessary.
