摘要： 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).

摘要： The occurrence of the halo phenomenon caused in a display panel unit is detected in a liquid crystal display device that displays an image in the display panel unit including color filters of a plurality of colors by respectively controlling emission ratios of a plurality of LEDs emitting lights of colors respectively corresponding to the plurality of color filters. Upon detection, a part of the display panel unit, for example, the channel number and the vicinity thereof are set as a non-detection area in which the detection of the halo phenomenon is restricted and the remaining area is set as a detection area. The chroma of light, which corresponds to mixed light from the plurality of LEDs, is reduced by controlling the emission ratios of the LEDs on the basis of the detection result in the detection area, so that the color of light is closer to white.

摘要： 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.

摘要： 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.

摘要： When a wide color gamut display displays video based on a video signal that complies with a narrower color reproduction range standard, in order to make full use of the feature of the wide color gamut display capable of displaying highly saturated and vivid reds, while eliminating the problem of seeing glaring images in the part of the red color region near the highest brightness and saturation, a video processing circuit (2) reduces and corrects the signal value of the input video signal, which represents the colors within the color range to be corrected, which is within a specified saturation range from the highest saturation to the middle saturation inside a specified hue range centered on the red hue in the color reproduction range (an expanded color reproduction range wider than the sRGB standard color reproduction range) of a liquid crystal panel (4), and which is within a specified brightness range from the highest brightness to the middle brightness inside that range, so that the saturation and brightness thereof change to saturation and brightness within a predetermined middle color range between the expanded color reproduction range and the color reproduction range of the standard to which the input video signal complies.

摘要： An image display device of the present invention includes a subframe generation section (10) for dividing one frame of a video signal into a first subframe during which at least a green (G) light source emits light, a second subframe during which at least a red (R) light source emits light, and a third subframe during which a blue (B) light source emits light. The subframe generation section (10) finds a difference between (i) a signal to be displayed, which signal is obtained from an aperture ratio corrected in the first subframe and luminance distribution of a light source corresponding to a red (R) video signal included in the first subframe and (ii) the red (R) video signal included in the first subframe, and corrects, according to the difference found in the first subframe, an aperture ratio corrected in the second subframe. This prevents insufficiency of luminance, and thus makes it possible to carry out an accurate color display.
