Abstract
A video signal processing system improves the image quality displayed in a CRT or printed by a video printer. In order to produce natural and fine video signals, pixel data corresponding to an intermediate position between two neighboring pixels, are produced from pixel data of the neighboring two pixels. The pixel data corresponding to the intermediate position is produced by a convolution operation with respect to the pixel data of the two neighboring pixels and a quantized value of an impulse response signal.
Claims2
A video processing system for processing a video signal to produce pixel data corresponding to an intermediate position between two neighboring pixels from pixel data of two neighboring pixels, each of said pixels being characterized by luminescence data, said system comprising:
- an input terminal for receiving said video signals, image memory means coupled to said input terminal for storing the video signal, and interpolation means connected to said memory means for receiving said video signal from said image memory means, said interpolation means comprising means for performing a convolution operation with respect to said luminescence data of the pixels contained in the video signal and with respect to an impulse response signal, said interpolation means producing pixel data corresponding to said intermediate position between two neighboring pixels.
