This paper describes an image rendering method for total digital archives of art paintings on a display device by considering surface properties and chromatic adaptation. First, we estimate the surface properties, including surface normal, surface-spectral reflectance, and reflection model parameters. We use a multi-band camera with six spectral channels. Multiple images of a painting are acquired with different illumination directions. All the estimated surface data are combined for image rendering. Next, we develop a chromatic adaptation transform for predicting appearance of the paintings under the illumination of an incandescent lamp and producing the full color images on a monitor. An incomplete adaptation index representing the degree of chromatic adaptation is defined based on color temperatures. The experimental results suggest the feasibility of the proposed.
