摘要： Provided is an image display device having pixels each of which includes sub-pixels of four or more colors and requires fewer dither matrices. This image display device includes a display section in which color filters of sub-pixel colors that are M colors in total including three principal colors of red, green, and blue, as well as at least one color other than the three principal colors are arranged regularly; and a gray-scale processing section (50) that performs gray-scale processing by a dither method with respect to an input image signal. The M sub-pixel colors are divided into N groups (G1 to GN) in such a manner that there is at least one group to which two or more colors belong. The gray-scale processing section (50) includes dither matrix storage ROMs (541 to 54N) that store N combinations of dither matrices corresponding to the N groups, respectively.

The plurality of pixels are each formed of a plurality of sub pixels including at least four sub pixel for displaying different primary colors from one another. The multiple primary color display device can sort the plurality of sub pixels which form each of the pixels into n number of virtual pixels (n is an integer of 2 or greater), each of which is formed of two or more sub pixels, and use each of the n number of virtual pixels as a minimum color display unit for providing display.

摘要： An image processing apparatus where noise in a dark region indicated by an input image signal may be reduced and perceived fineness of texture may be enhanced is provided. It includes: a high pass filter (11) that extracts a high frequency component from an input image signal; a sign determining unit (12) that determines the sign of the high frequency component; a brightness value calculator (14) that determines the brightness value of the input image signal; and a parameter determining unit (gain value determining unit) (13) that determines a parameter (for example, a gain) to be used in the image processing for the high frequency component processor based on the brightness value and the sign information. The parameter determining unit (13) determines the parameter such that the degree to which shoot in the high frequency component is reduced when the sign information indicates positive is larger than the degree to which shoot in the high frequency component is reduced when the sign information indicates negative if the brightness value of the input image signal is not greater than a predetermined value.
