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： 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： A histogram generation portion calculates a prescribed feature value of a pixel and the maximum feature value for the pixel, for each pixel of one frame of an input video signal. Then, the ratio of the feature value of the pixel to the maximum feature value is calculated for each pixel as an index of color brightness, and a histogram generated wherein the numbers of pixels are integrated by index value. An enhancement processing portion applies gain and carries out an enhancement for pixel values wherein the index in the histogram which the histogram generation portion generates is greater than or equal to a prescribed threshold. The feature value is treated as a luminosity (L*) which is defined with CIELAB chroma space. Additionally, the feature value may be data which has the maximum tone value among pixel RGB data, or may be a luminosity value (Y) of the pixel.

摘要： A portion of a video signal for emitting light is detected, and the display brightness of the light emission portion is enhanced and displayed in a more conspicuous manner, whereby the sense of radiance is increased and the image quality is improved. A light emission detector (2) of the video display device generates a histogram in which the number of pixels is integrated into a predetermined feature quantity of an input video signal; and detects an upper region of a predetermined range of the histogram as a light emission section. An area-active control/brightness stretch portion (4) stretches and boosts the brightness of a backlight portion (6). A mapping portion (3) reduces the brightness of the video signal in a non-light-emission section, which excludes the detected light emission section. An increase in the screen brightness of the non-light-emission section is thereby suppressed, and the display brightness of the light emission section is enhanced.

摘要： The present invention makes possible video expressions with increased feeling of brightness and increased contrast feeling and to be able to prevent the feeling of brightness and the contrast feeling from becoming unnatural during execution of the multi-screen display. This video display device comprises: a control portion (a signal processing portion (1); an area-active-control/luminance-stretch-portion (4)) that controls a displaying portion (8) and a backlight portion (6); and a display instruction detection portion (13a) that detects display instructions of first and second input video signals. The control portion stretches and increases the luminance of the backlight portion (6), and also controls a light emitting portion enhancement processing according to a result of the detection. In the light emitting portion enhancement processing, the display luminance of a light emitting portion is enhanced by producing a histogram by integrating number of pixels for a predetermined feature amount relating to the brightness of the input video signal, detecting an upper region of a predetermined range of the histogram as the light emitting portion, and reducing luminance of a video signal of non-light emitting portion except the light emitting portion of the input video signal.

摘要： A video display device increases a feeling of brightness and expresses a video with high contrast by detecting a part of a video signal that emits light, enhancing the display luminance of the light-emitting part, and displaying the part. A light emission detection portion (1) uses a prescribed feature quantity related to the brightness of an input video signal, predetermines the light emission quantity for the video signal on the basis of the relationship with the feature quantity, and detects the light emission quantity for each input video signal frame from the feature quantity. A backlight luminance stretch portion (3) stretches the light source luminance of the backlight according to the light emission quantity detected. A video signal luminance stretch portion (6) stretches the video signal according to the light emission quantity or the luminance distribution of the input video signal.
