We investigate the display of color image sequences using a model-based approach to multilevel error diffusion. We extend Bouman and Kolpatzik's technique for design of optimal filters to the temporal dimension. Our model for the human visual system accounts for the spatial and temporal frequency dependence of the contrast sensitivity of the luminance and chrominance channels. We observe an improvement in image quality over that yielded by frame-independent quantization, when the frame rate is sufficiently high to support temporal averaging by the human visual system.
