Abstract: 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.

Abstract: 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.

Abstract: It is expected to provide an image display apparatus and image display method that can reduce the risk that an image quality is undermined due to a halo phenomenon caused by the leak of light passing through a non-corresponding color filter from a LED. The image display apparatus can respectively control luminous efficiencies of plural color LEDs, i.e., R-LED (11a), G-LED (11b) and B-LED (11c) that emit light through a color filter to a displaying unit. The image display apparatus obtains luminous efficiencies for a frame of RGB image signal (S2), calculates a light leak amount and then detects whether the halo phenomenon may occur or not (S3-S5). When the halo phenomenon is considered to occur, the luminous efficiencies of LEDs (11a, 11b, 11c) included in the liquid crystal display apparatus are controlled to make the light from the LEDs (11a, 11b, 11c) become close to white light (S8).

Abstract: When conducting video display with a wide color gamut display based on a video signal conforming to a standard (sRGB standard and the like) having a color reproduction range narrower than that of the wide color gamut display, the video processing circuit 2 corrects a color in a prescribed correction target color range partly including a red hue reference range as a center part in the color range of an equal hue from achromatic colors having the lowest saturation to red having the highest saturation in an expanded color reproduction range but not including red having the highest saturation in the expanded color reproduction range, so that the hue may change to a hue akin to yellow in the expanded color reproduction range. In so doing, the hue in the red hue reference range changes to red hue in the color reproduction range conforming to the sRBG standard. Furthermore, the hue change ratio into the hue akin to yellow becomes smaller in a color having a long distance from the red hue reference range in the expanded color reproduction range than a color having a distance close thereto. As a result, the wide color gamut display displayable of bright red having a high saturation can be fully utilized, while at the same time solving the problem of hue displacement in displaying red having an intermediate saturation.

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.

Abstract: In order to simply and easily implement an elimination of a color deviation and a color adjustment for a color correction to a favorable color in an arbitrary portion of a color region in a color reproduction range, a video processing circuit 2 corrects a luminance, a saturation and a hue of a color by the correction quantity corresponding to a reference correction coefficient with regard to a signal value of an input video signal indicating a color within a designated color region defined by a designated range of the luminance, the saturation and the hue when the color indicated by the signal value is a color in the center of the designated color region or at a core for occupying a predetermined range around the center. Otherwise, the video processing circuit 2 corrects the luminance, the saturation and the hue of the color of the signal value by the correction quantity gradually smaller as a position in a color space of the color indicated by the signal value approaches a boundary position of the designated color region.
