Abstract

An image processing device is capable of inhibiting the moire and the false color from occurring in the case of performing color display using four colors of sub-pixels. The image processing device has filter processing sections. The filter processing sections limit frequency bands of signals R, G, B, and W in an X direction and a Y direction in accordance with a positional relationship between the sub-pixels corresponding to each of the colors and the other sub-pixels. Further, the filter processing sections control a frequency response of image signals of the respective colors in accordance with an amplitude of a high frequency component of the image signal corresponding to each of the other colors.
