Abstract
In this report we present a new time-dependent tone mapping model which describes the ability of the human vision to adapt to even strong changes in the luminance of the surroundings. This ability depends on time; in fact the human visual system needs a determined amount of time until reaching the final stage of adaptation. Our model accepts the CIEXYZ values of an image as input and converts them into RGB values reproducible on a monitor. This work is based on the retinal model presented by Pattanaik et al. , but introducing substantial modifications. In fact, we define a new dynamic model which describes the time dependence of the human visual system, utilizing different filters; the cromatic adaptation is taken into account by introducing the model of von Kries. Furthermore, we introduce new techniques of gamut mapping and conversion between the values of retinal response and luminance of the display.Additional Files and Images
