| Abstract(in English) | Recent progress of the facial image processing technology has made it possible to study on the perception of facial expressions by means of the method of psychophysics with the use of realistic facial stimuli. This paper reported three experiments as our first step along with it. Each experiment attempted to clarify about the relationship between the strength of facial expressions and our sensation. Experiment 1 measured the thresholds of the perceived differences in facial appearance at 5different levels of strength of expressions for 'surprise' and 'anger'. Experiment 2 measured the same ones but for 'happiness' and 'Sadness'. Those results showed that there exist two types of relationship between the physical strength of expressions and the perceived one, which seem to be caused by two different visual properties of expressions. Experiment 3 confirmed the certainity that subjects in the previous experiments made their judgments of deifferences of facial images based on perceiving the expressions on the images by means of measuring the same thresholds for the inverted stimuli of 'surprise. |
