Abstract
An image processing device, to convert a first image data into a second image data having a higher image quality, includes: a predicted tap extracting unit to extract multiple pixels as a predicted tap for prediction computing; a level limit class tap extracting unit to extract multiple pixels as a level limit class tap for level limit classifying processing; a waveform class tap extracting unit to extract multiple pixels as a waveform class tap; a level limit classifying unit to classify the pixel of interest, based on a ratio between a level width and a dynamic range of the pixels making up the level limit class tap; a waveform pattern classifying unit to classify the pixel of interest; a prediction coefficient output unit to output a prediction coefficient corresponding to a combination of a level limit class and a waveform pattern class; and a prediction computing unit.
