Signboard is the end medium of advertising, and it is also an important element of cityscape. In this study, we carried out a field investigation on image communication of signboards. The subject was the wedding service industry on Section 2 to 3 of San Min Road in Taichung City, this area is the so-called ”Wedding Street”. According to semiotics, this study analyzed the perspective between Paradigm and Syntagm, in which image system, including the appearance, frame shape, title and trademark, was transformed into the sentence structure relationship of cross axle, and then the vertical axle choices of each phrase are used to analyze the way that their meanings were formed. The ”Image Scale”, which was developed by Shigenobu Kobayashi from Nippon Color & Design Research Institute, was used to mark the image position of the elements in the signboard according to the key elements of color, shape, and material.The results showed the homogeneity among ”feminine”, ”happy and romantic”, fashion and noble”, and ”luxurious and influential”. We found that the symbol of wedding signboard refers to the characteristics of the overall consumer culture, and the media is obviously involved in the lifestyle during the process of image production. This study also illustrates the diversity of image system interpretation. While evidential verification was not devised in this study, several issues for future exploration have been touched off. The results could be served as reference for design educators, researchers, and practitioners.
