an image processing device able to display an image in high quality in a color image display using fixed pixels , which drives a display device making pixels of r , g and b arranged inside each of a plurality of areas on a screen emit light to display a designated color in unit areas , wherein a signal generation circuit determines a pixel of which an arrangement position is not matched with a reference position of the unit area used for reference by a first pixel signal as a target to be interpolated among pixels of r , g and b , generates a second pixel signal which uses the arrangement position of the pixel to be interpolated as a reference on the basis of the first pixel signal .
