摘要： 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.

摘要： 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.

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.
