    摘要: A local contrast enhancement method transforms a first plurality of color components of a first visual color image into a modified brightness component by using a first transformation. The first plurality of color components are in a first color space. The modified brightness component is a brightness component of a second color space. The second color space also includes a plurality of chromatic components. The method transforms all the color components of the first color space into the chromatic components of the second color space. The method then transforms the modified brightness component and the chromatic components of the second color space into a plurality of new color components, in the first color space, of a second visual color image. The method transmits the plurality of new color components to a device such as a display device. The second visual color image has enhanced contrast in comparison to the first visual color image.
