A formula using the contrast profile method is proposed to predict the brightness of even complicated luminance distribution in the real scene. The appropriateness of using the contrast profile method is first explained based on the multi-channel model of the visual system. Then, the previous formula using target size as a parameter is transformed into a formula using detected spatial wavelength as a parameter. Finally, the formula is checked experimentally using complicated luminance images as stimuli.
