Abstract (in Japanese) (See Japanese page) 
(in English) Characters in scene image are often hard to detect, i.e., not conspicuous. Thus, one of the main tasks for camera-based character recognition is the detection of characters in scene image. There are many past attempts for this difficult task. This paper investigates the essence of this task, that is, ``what is conspicuous character images?'' In order to have an example of the conspicuous character image, we use the relation between the subspace of non-character images and that of character images. Specifically, we try to select a image in the set of character images furthest from the subspace of non-character images.
