Abstract:
1. An image processing device adapted to supply an image signal to a display device having pixels arranged in a matrix, each of the pixels being composed mainly of four sub-pixels arranged two by two in a first direction and a second direction intersecting with the first direction, one of the sub-pixels constituting each of the pixels corresponding to white, the image processing device comprising: a first filter processing section adapted to perform a filter process of limiting frequency bands in the first direction and the second direction of a first image signal according to an arrangement of a first sub-pixel and a second sub-pixel located in a diagonal direction with respect to the first sub-pixel, the first image signal adapted to display the first sub-pixel corresponding to white; a second filter processing section adapted to perform a same filter process as the first filter processing section of limiting frequency bands in the first direction and the second direction of a second image signal according to an arrangement of the first sub-pixel and the second sub-pixel, the second image signal adapted to display the second sub-pixel; a third filter processing section adapted to perform a filter process of limiting a frequency band in only the second direction of a third image signal according to an interval in the second direction of third sub-pixels, the third image signal adapted to display the third sub-pixels which are adjacent to the first sub-pixels in the first direction; and a fourth filter processing section adapted to perform a filter process of limiting a frequency band in only the first direction of a fourth image signal according to an interval in the first direction of the fourth sub-pixels, the fourth image signal adapted to display the fourth sub-pixels which are adjacent to the first sub-pixels in the second direction.
