Abstract
With the increasing number of on-board visual displays such as navigation systems, it is important to improve visibility of on-board displays in various visual environments, such as driving on a snow-covered road in fine weather. We propose a new displaying method based on the luminance adaptation, one of the human vision properties, associated with environmental luminance changes during driving. In this method, the luminance and the saturation of the display is compensated according to the adaptation luminance of the driver in order to perceive the constant brightness of the display even in the different environmental luminance. Experimental results of subjective and objective evaluation comparing the conventional display indicate the effectiveness of the method.
