This article is intended to study the fundamental character of signification-the signifier (signifiant) and the signified (stgnifie)-of images. The word image, in this paper, only purports the image produced by mechanical means, i. e. the camera. This image is common to photograph, film and television which play important roles as media of communication or that of representation in our time. Roland Barthes, in his "Rhetorique de l'image", analyzed the image and seperated out three kinds of messages, that is, (1) linguistic, (2) coded iconic or symbolic (connotation), (3) noncoded iconic or literal (denotation). A semiological analysis like this, however, can not fully make clear the specific character of signification peculiar to images. Then, with this analysis as the startingpoint, but apart from the standpoint of semiology, a more precise examination about the signification of images must be required. The investigation of messages at the level of denotation especially lead us to the Ontology of the image. The other aim of this paper is to go into the question of how we perceive the objects in the image like real objects, and how we accept literal or symbolic messages from images. From this point of view, the existence or the meaning and implication of code will be thoroughly reconsidered.
