Abstract:
An image processing device supplies an image signal to a display device having pixels being composed mainly of four sub-pixels arranged two by two in a first direction and a second direction. The image processing device includes a first filter processing section adapted to perform a filter process of limiting frequency bands in the first direction and the second direction of the image signal adapted to display a first sub-pixel corresponding to white in a manner corresponding to an arrangement of both of the first sub-pixel and a second sub-pixel located in a diagonal direction with respect to the first sub-pixel, and a second filter processing section adapted to perform a filter process of limiting frequency bands in the first direction and the second direction of the image signal adapted to display the second sub-pixel in a manner corresponding to an arrangement of the first sub-pixel and the second sub-pixel.
