The diversity of smiling face representation is expressed based on average images of 10 university students' smiles. 52 samples are made from the average images that changed the strength, the interval of both eyes, the interval between eyes and a mouth and the shape of mouth. 30 respondents have evaluated the impression to samples by SD method, and various smiles were shown in the impression plane by principal component analysis. As a result, the vertical axis of the impression plane to smiles was assumed to be a preference, and the horizontal axis was assumed to be energy. It was found that the interval between eyes and a mouth that was the feature element of an individual face influences the preference. The energy degree of smiles had a connection with to the shape of mouth. The preference of the intensity change of smiles was higher than the caricature smiles.
