<p>A predictive coding device comprises sampling means for sub-nyquist sampling a video signal and predictive coding means for receiving a sampling value from said sampling means and outputting an encoded code, in which the predictive coding means including an encoder for encoding a difference between the sampling value and a predicted value corresponding to the sampling value, and outputting the encoded code, and a predictor for generating the predicted value using only an array of pixels in a vertical direction of a screen with respect to a sampling value of a pixel to be encoded by the encoder.</p> |
