摘要： A method and apparatus for generating a white signal component and for controlling the brightness of an image are provided. In the above method and apparatus, the brightness increases of Red, Green and Blue, the saturations of which are not decreased from an input image are calculated using a vector, and the minimum value of such increases is utilized as the input value for the white component. Further, by adding brightness control components of RGB color to the input RGB signals, brightness increases in the direction of the original colors instead of the achromatic one are possible, which is the way the white component is added so as to increase the luminance of color display devices representing a color using a color filter such a flat panel display. Accordingly, a color saturation of the image is not decreased even with addition of the achromatic color component. In other words, in converting a signal from the three colors such as RGB into the four colors inclusive of white component, the present invention is capable of increasing the brightness without reduction of saturation as well as extracting the white component in an easy and efficient way, which enhances the performance of image processing apparatuses such as color display devices and the like.

The apparatus for estimating illuminant chromaticity includes an image input unit for receiving a color image, a highlight detector for extracting highlight regions from the color image, a highlight parameter calculator for mapping the highlight regions to chromaticity coordinates and calculating geometric presentation parameters of the shape of the distribution of chromaticity coordinates, a perceived illumination illuminant chromaticity estimator for estimating illuminant chromaticity in the color image using a perceived illumination estimate scheme, and a correct chromaticity calculator for selecting a predetermined number of geometric presentation parameters near the illuminant chromaticity estimated by the perceived illumination illuminant chromaticity estimator among the geometric presentation parameters and calculating final illuminant chromaticity using the selected geometric presentation parameters. The method for estimating illuminant chromaticity using perceived illumination and highlights is used for estimating illuminant chromaticity from a color image. This method, which is a combination of two kinds approaches, a perceived illumination estimate scheme and a highlight estimate scheme, considers the characteristics of highlights based on stable illuminant chromaticity estimated from perceived illumination, thereby improving accuracy.

摘要： An image segmenting apparatus and method is provided. The image segmenting apparatus includes an initial image segmenting unit, a region structurizing unit and a redundant region combiner. The initial image segmenting unit converts color signals of an input image into a color space which is based on predetermined signals, and segments the input image into a plurality of regions according to positions of color pixels of the input image in the color space. The region structurizing unit classifies the plurality of regions into layers according to horizontal, adjacent relation and hierarchical, inclusive relation between the regions, and groups adjacent regions into region groups in each layer, so as to derive a hierarchical, inclusive relation between the region groups. The redundant region combiner determines the order in which adjacent regions are combined according to the horizontal, adjacent relation between regions and the hierarchical, inclusive relation between region groups. The redundant region combiner also determines whether to combine adjacent regions according to the determined combination order, and combines adjacent regions if the adjacent regions are determined to be substantially the same. Even if regions appears to be adjacent each other in a region adjacent graph (RAG), a structural inclusive relation between regions can be derived by excluding the combination of the regions or rearranging their combination order according to a hierarchical structure. Subsequently, the mutual relation between two regions can be inferred from the inclusive relation even if the color signals of the two regions, for example, a region in a highlighted area and a region in its surrounding area, are not similar to each other.
