A multiple primary color display device includes a plurality of pixels located in a matrix including a plurality of rows and columns. The pixels are each formed of at least four sub pixels for displaying different primary colors, which can be sorted into n number of virtual pixels, and use each of the n number of virtual pixels as a minimum color display unit for providing display. The sub pixels which form each of the virtual pixels include a sub pixel common to another of the virtual pixels. When a line having a width corresponding to the n number of virtual pixels is displayed, two sub pixels which are located at both of two ends, in a width direction, of the line and display a certain identical primary color to each other have a luminance lower than the original luminance that the two sub pixels.

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.

A multiple primary color display device (100) includes a plurality of pixels (P) located in a matrix including a plurality of rows and a plurality of columns. 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. The two or more sub pixels which form each of the n number of virtual pixels include a sub pixel common to another of the n number of virtual pixels. When a line having a width corresponding to the n number of virtual pixels is displayed, two sub pixels which are located at both of two ends, in a width direction, of the line and which display a certain identical primary color to each other have a luminance lower than the luminance that the two sub pixels originally have.

A display device according to the present invention includes a plurality of pixels arranged in a matrix. Each of the plurality of pixels is formed of four or five types of sub pixels that display different colors from each other. In each pixel, a first sub pixel that displays a color having the highest luminance and a second sub pixel that displays a color having the second highest luminance are located so as not to be adjacent to each other. The four or five types of sub pixels include a plurality of display units, each of which is capable of displaying a specific color and is formed of one sub pixel or two or more continuous sub pixels. In the display device according to the present invention, when an input image has a resolution higher than a display resolution defined by a total number of the plurality of pixels, each of the plurality of display units is usable as a virtual pixel for providing display. According to the present invention, a multiple primary color display device which suppresses the decline of display quality even when the resolution of an input image is higher than the resolution of the display device is provided.

In order to display an image with a high contrast ratio while suppressing power consumed by a multi-display device and to adjust brightness of images displayed on image display devices, the multi-display device includes light emission APL value adjusting means 102. The light emission APL value adjusting means 102 sends, to light emission control means, a light emission APL value that has been adjusted, on the basis of light emission APL values calculated by light emission APL value calculating means of image display devices 11 to 19, so that total light emission power value of image-display light-emitting means 6 does not exceed an allowable power value and images are displayed at predetermined brightness.
