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.

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： 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.
