摘要： Provided are a method and apparatus to restore an image with a high resolution from an image obtained through a miniaturized camera module. The method includes obtaining a plurality of original color-separated images through a camera module including a plurality of lenses and a plurality of image sensing areas corresponding to the lenses, respectively, generating a first intermediate image corresponding to the sensing areas, the first intermediate image being divided into a plurality of pixel groups, generating a second intermediate image by mapping pixel information of pixels at identical positions in respective original color-separated images onto a predetermined pixel of a pixel group in the first intermediate image corresponding to the identical position, and generating a final image by interpolating the second intermediate image. The pixel group includes a plurality of pixels corresponding to an arrangement pattern of color filters.

摘要： An image retrieval method and apparatus independent of an illumination change are provided. The image retrieval method involves: inputting a query image; detecting an illumination color from the query image and converting the illumination color into a standard illumination color; extracting color information of the query image by using color descriptors; and retrieving a similar image by comparing the extracted color information with color information of a database which converts a variety of images into images of standard illumination colors and extracts and stores the color information of the images in advance. According to the method, without changing the structures of color descriptors or a similarity comparison using color information, an image retrieval independent of illumination changes is enabled by adding only a preceding step of standard illumination conversion.

摘要： A method for displaying a color image under various illuminants is provided. In the color image displaying method, the chromaticity of an illuminant existing in a space in which a predetermined display device is located and the luminance ratio of a white paper on the display under the illuminant with respect to a luminance of the display device are measured. A shift ratio of a visual white of the display device using the chromaticity and the luminance ratio is determined. A new visual white of the display device in which the influence of the illuminant is removed using the shift ratio is obtained. A white of a displayed color image on the display device is shifted to the new visual white. Therefore, a visually consistent color image can be reproduced on the color display device under any illuminant.

摘要： In determining a color temperature in a color display device, the present invention comprises the steps of: producing a patch set I composed of a plurality of patches which appear gray under respective illuminant components and producing a patch set II composed of a plurality of patches to be a metameric pair with a neutral gray emitted from the respective illuminant components, under a specific illuminant; visually detecting peripheral illuminant components by selecting patch having identical color to that of patch having an equivalent energy spectral reflection degree in the patch set I; and determining a color temperature of the display device from the patch set II by using the detected illuminant component. Thus, the present invention provides color temperature information in producing a profile of the device required by a CMS by determining the color temperature of the display device considering the peripheral illuminant component without using a colorimeter.
