Wearable computer can give the user a new service suited for user's condition. The object recognition is one of the indispensable technology in order to realize new service for wearable computer. In the object recognition, the color information is one of the important information. However, it is difficult to use color information since color information tends to change with surrounding light source environment. If the light source environment is known, it will become easy to use color information for object recognition. There are some studies for estimating the light source environment. However, since these researches assume fixed environment, they are not suitable for a wearable computer. This paper proposes the newly light source environment estimation method. This method uses fish-eye camera and takes directly light source environment. Since this method can estimate the lighting condition that consists of different light source types, the method makes it easier to analyze images on wearable computing.
