摘要： A motion vector detection method comprises extracting a first block including a plurality of pixels from a first frame of the image, detecting a second block from a plurality of blocks of a second frame of the image by block matching, the second block including the maximum number of pixels each indicating an absolute difference value not more than a first threshold with respect to each of the pixels of the first block, and computing a first motion vector between the first block and the second block.

摘要： An image processing apparatus calculates an absolute difference in pixel values between each pixel (target pixel) of the image and each of neighboring pixels of the target pixel, and a sum of the absolute differences with respect to the target pixel, calculates a threshold using the sum of the absolute differences with respect to the target pixel and a weight previously determined, the threshold being used as a reference for determining whether the pixel values of the neighboring pixels are used in a smoothing process for the target pixel, and performing a smoothing process by means of an edge-preserving smoothing filter, based on whether the absolute difference in pixel values between the target pixel and each of the neighboring pixels of the target pixel exceeds the threshold.

摘要： An image display apparatus includes an image displaying unit that includes a light source unit and a light modulation device, a histogram generating unit, a light source luminance calculator, a function storing unit, a first evaluation value calculator, a second evaluation value calculator, a third evaluation value calculator, a function acquiring unit and a control unit. The function acquiring unit acquires a plurality of the third evaluation values by repeating processing by the first to third evaluation value calculators with modification to a level conversion function and acquires a level conversion function that has a smallest third evaluation. The control unit supplies a signal of a converted video resulting from conversion of the image with the acquired level conversion function to the light modulation device.

摘要： An objective color for a target color is set based on characteristic of the target color on a hue area to which the target color belongs in a color space represented by lightness, chroma and hue, and a shape of the most outer point of a color gamut reproducible by an output device on the hue area. A correction coefficient is calculated based on lightness, chroma and hue of the target color, lightness, chroma and hue of the objective color, a distance between the most outer point and the target color in the color space, and a distance between the most outer point and the objective color in the color space. A color correction quantity of each pixel of the image is calculated based on a distance between the target color and the objective color in the color space, a distance between the target color and a color of each pixel in the color space, the correction coefficient, and lightness and chroma of each pixel. The color of each pixel is corrected based on the color correction quantity.
