    摘要: A method for enhancing the color of an image to be displayed on a display includes receiving an image having a plurality of pixels where each of the pixels has a plurality of color components. The image is filtered using a spatial filter in such a manner that the lower frequency content of the image is enhanced in such a manner that the dynamic range of the lower frequency content is increased. The filtered image is modified such that the higher frequency content of the image to obtain a modified image that includes the higher frequency content and the lower frequency content.

    摘要: A system for characterizing the temporal luminance response of a liquid crystal display. A liquid crystal display may be forced at an initial time from a first luminance value to a measured second luminance value. The second luminance value may be measured at a predetermined time after the initial time.
