    摘要: A method, medium, and system generating and/or implementing a line profile to compensate for displacement differences in an optical modulator. In the method, a test chart made up of a predetermined number of patches that are arranged at regular gray scale intervals is designed. The designed test chart is displayed using a one-dimensional optical modulator, and the displayed test chart is captured using a camera, thereby acquiring a two-dimensional image. Thereafter, the two-dimensional image is divided into a plurality of regions, and the average value of intensity of light is calculated for each horizontal line of the regions. Finally, a line profile is generated and/or implemented for respective horizontal lines using the calculated average values.

    摘要: A method and apparatus for expanding bit resolution using local information of an image receives an input image. First, second and third threshold value used to enhance bit resolution, to detect a texture and to detect a pattern, respectively, are determined considering global information of the input image. A texture existing in a mask region composed of surrounding pixels within a predetermined range around a current pixel is determined using the second threshold value. A regularly repeated pattern existing in the mask region is determined using the third threshold value if no texture exists in the mask region. The first threshold value is decreased if a texture or pattern exists in the mask region. Values of mask region pixels are adjusted depending on the first threshold value, and bit resolution of the current pixel value is enhanced using a resultant value obtained by filtering the adjusted pixel values.

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.
