To clarify the effective luminance ratio at transient adaptation to introduce the effective luminance concept into the dynamic evaluation method, experimants by using Line and Londolt targets were conducted and found followings : (1) Visibility at transient adaptation can be analyzed only by use of two factors that are the sensitivity of eye and the effective luminance, as same as the visibility analysis of steady state of adaptation. (2) The effective luminance function F (θ) with θ<80 minutes and the effective luminance ratio at transient adaptation are determined independently of visual sensitivity, and they are equal to the ones obtained at steady state of adaptation. (3) The effective luminance at transient adaptation is determined independently of adaptation luminance when there are no significant luminance distribution in the field.
