Abstract
A head mount display device includes a display panel which displays image based on an image signal, a calculator which calculates an initial image luminance and a watching image luminance based on an equation 'log(Lth)=clog(La)+clog(w)+c, where Lth is a determination luminance, La is an adaptive environment luminance, w is an offset, c1 is a first constant, c2 is a second constant, and c3 is a third constant' that is a modelling for a relationship of an adaptive environment luminance in which eyes of a user are adapted and a determination luminance in which the eyes of the user do not recognize a discomfort, and a luminance controller which changes the initial image luminance of the image to the watching image luminance during an adaptive time.
