## Abstract

An image display device includes a color image separator, a filter controller, a filter processor, a display image generator, and a display. The color image separator separates red image data, green image data, and blue image data from input image data. The filter controller sets a plurality of pixel combination patterns for performing filter processing on the red image data, green image data, and blue image data. The filter processor performs filter processing for each pixel combination pattern on the red image data, green image data, and blue image data. The display image generator combines the filter-processed red image data, green image data, and blue image data, for each filter processing by the same pixel combination pattern, to generate a plurality of full color images. The display includes color filters.

## Claims

### Claim 1

An image display device comprising:
a color image separator configured to separate red image data, green image data, and blue image data from input image data;
a filter controller configured to set a plurality of pixel combination patterns for performing filter processing on the red image data, green image data, and blue image data;
a filter processor configured to perform filter processing for each pixel combination pattern on the red image data, the green image data, and the blue image data;
a display image generator configured to combine the filter-processed red image data, green image data, and blue image data, for each filter processing by the same pixel combination pattern, to generate a plurality of full color images; and
a display comprising color filters,
wherein each of the pixel combination patterns comprises three or more adjacent pixels, and each of the three or more adjacent pixels comprises one or more pixels corresponding to red, green, and blue in an arrangement pattern of the color filters.

### Claim 2 (depends on 1)

The image display device according to claim 1, wherein the filter controller, the filter processor, or display image generator is configured to control to switch the plurality of full color images within one frame period.

### Claim 3

An image processing method comprising:
separating red image data, green image data, and blue image data from input image data;
setting a plurality of pixel combination patterns for performing filter processing on the red image data, green image data, and blue image data;
performing filter processing for each pixel combination pattern on the red image data, green image data, and blue image data; and
combining the filter-processed red image data, green image data, and blue image data, for each filter processing by the same pixel combination pattern, thus generating a plurality of full color images.
