    摘要: In the technical field of video cameras gamma correction is an often used technique to compensate the non-linear effects of the CRT (cathode ray tube), in order to enhance visibility in images to be displayed. Gamma correction is—by way of example—expressed by the gamma function: A process for enhancing detail visibility in an input image comprising a step of applying a first transfer function (11) to the input image, thereby generating an intermediate image; a step of performing a statistical measurement (12), Mmt (2) on the intermediate image; a step of applying a second transfer function (14) to the intermediate image, thereby generating an output image; a step of performing a statistical measurement (15), Mmt (3) on the output image, a step of determining gain parameters gg, gk for the first and the second transfer function (11, 14) on basis of the statistical measurement results (8, 12, 15), Mmt (1), Mmt (2), Mmt (3) is proposed.
