INITIAL VISUAL INFORMATION FOR THE CONSTRUCTION OF SPACE RECOGNITION TO BRING ABOUT THE COLOR CONSTANCY

摘要

Recognized visual space of illumination RVSI theory is a theory to explain color appearance of objects and lights1'. It says that when one enters or looks at a space he first recognizes the existence of the space and understands the illumination that fills the space. The understanding leads his/her brain to adapt the visual system to the illumination. For the recognizing the space and for the understanding of the illumination he must see objects in the space. The objects that he sees first are called initial visual information IVI. It becomes a fundamental interest how much IVI is needed to construct a RVSI for a space. Chunvijitra et al.2) employed a two rooms technique, or environment-stimulus independent illumination technique, and investigated the effect of TVI by employing artificial flowers as TVI. It was found that even one piece of carnation flower was already very effective. In this paper a still small amount of IVI is used to find out minimum IVI to for the construction of RVSI.
