| Research Abstract |
Digital museum is the digital archive of valuable paintings and is the realistic image reproductions of them on a display device. The color appearance and the impression of a painting differ markedly with the illuminations, i.e., they depend on their spectral power distributions such as a daylight or a candlelight and their illuminance levels. Extensive studies have been carried out to reproduce color images under various illuminations by taking into account the chromatic adaptation of human visual system.
In this report, it is described that spectral reflectances of three types of painting such as Japanese, oil color and water color paintings are accurately recovered by the use of image data without prior knowledge of color materials used to paint them and that the colors of a painting under various illuminations are reproduced faithfully on a display device through the use of the recovered spectral reflectances.
