Abstract
An image processing device includes a first filter that filters the image signal to output a first image signal, a second filter that converts the image signal corresponding to a predetermined pixel to a second image signal based on image signals corresponding to a plurality of peripheral pixels adjacent to the predetermined pixel, a third filter that filters the second image signal from the second filter to output a third image signal, a fourth filter that filters the third image signal from the third filter to output a fourth image signal, and an image synthesizer that synthesizes the first image signal from the first filter and the fourth image signal from the fourth filter.
