Abstract:
A method of adjusting a brightness of an input image includes performing brightness conversion on a brightness component value of the input image, and compensating a chroma value of the input image based on input image information and a brightness value obtained from the brightness conversion, wherein the input image information includes a chroma component value and the brightness component value of the input image.
Abstract:
An image processing method and apparatus for a curved display device are provided. The image processing method includes acquiring physical curvature information related to the display device, determining a center region of an input image based on the physical curvature information, generating a pixel-by-pixel spatial indexed gain based on the determined center region of the input image, and correcting a pixel value of the input image by using the pixel-by-pixel spatial indexed gain.
Abstract:
Methods, apparatuses and storage mediums for processing color signals of an image are provided. A method includes converting an input signal in a first color space into a luminance component and a saturation component in a second color space, determining a boundary of the second color space by using the luminance component and the saturation component, determining whether the converted input signal is outside the boundary, and matching the saturation component so that the converted input signal outside the boundary of the second color space enters the second color space. The method may be carried out by a non-transitory computer readable storage medium. An apparatus includes a color signal a color space converter configured to convert an input signal in a first color space into a luminance component and a saturation component in a second color space; a color space boundary determiner configured to determine a boundary of the second color space by using the luminance component and the saturation component, and determine whether the converted input signal is outside the boundary; and a saturation matcher configured to match the saturation component so that the converted input signal outside the boundary of the second color space enters into the boundary of the second color space.
