    摘要: An auto white controlling method and apparatus are provided. The method includes providing a plurality of feature points having color features of an image if the image includes an object having dominant chroma; detecting a first illuminant according to the feature points; calculating a mean chroma of data showing a chroma difference within a threshold value with a chroma of the first illuminant among data constituting the image; and providing a second illuminant by mapping the mean chroma to an illuminant locus. The apparatus includes a feature-analyzing module that provides a plurality of feature points having color features of an image; and an illuminant-detecting module that detects a first illuminant by using the feature points, calculates a mean chroma of data showing the color difference within a threshold value with the chroma of the first illuminant, and provides a second illuminant by mapping the mean chroma to an illuminant locus.

    摘要: A high dynamic range (HDR) image generating apparatus and method is provided. The HDR image generating apparatus may set an auto-exposure time, a long exposure time, a short exposure time, and a reference exposure time. The auto-exposure time may be set to be shorter than the long exposure time, the short exposure time may be set to be shorter than the auto-exposure time, and the reference exposure time may be set to fall within a range between the auto-exposure time and the short exposure time. The image generating apparatus may obtain a first image with the long exposure time and a second image with the reference exposure time, may correct motion in the first image and adjust a dynamic range of the second image, and then may composite the resultant first and second images to generate a high dynamic range image.

    摘要: A method, medium, and apparatus compensating for differences in the persistence of phosphors in a display panel. The method of compensating for differences in persistence of phosphors in a display panel, having two or more light-emitting elements with different response characteristics, may include compensating for the response time of a first light-emitting element that represents the longest response time, selecting data response time for a second light-emitting element, which is different from the longest response time, and compensating for the differences in the persistence of phosphors due to a difference between the response times of the first light-emitting element and the second light-emitting element by compensating for the selected video data based on the compensated video data for the first light-emitting element.
