Abstract:
According to one embodiment of the invention, a method is provided for aspect ratio distortion minimization. The method includes receiving input pixels from a video source. The method then determines an input position and scale factor for each input pixel. A count value determines that a pixel should be outputted. A polyphase finite impulse response filter is centered on a particular input pixel based on the count value. An output pixel is generated using the polyphase finite response filter on a particular input pixel based on the count value and output pixels are outputted.
