Abstract The authors have been analyzing images by eye movement. For this purpose, it is necessary to decompose the eye movement into a component to accept information from a gazed object and a component to shift the gazing point. The point considered in the foregoing is called the gazing point, which is defined in this paper based on the property of the pursuit eye movement. Eye movement velocity of 5 deg/s is used as the threshold to separate the two components. As a result, it is made possible to separate clearly the eye movement into the gazing point component and the shift between the gazing point. A vision analyzer based on this definition of the gazing point was developed, which can analyze comprehensively the eye movement in real‐time. As an example of the application of the vision analyzer, the difference of the eye movement in watching the VDT image and the usual dynamic picture is analyzed. Furthermore, as an application to the analysis of art, an experiment was made as a reference material for the analysis of Sharaku's ukiyo‐e painting. The results of experiments are described, indicating that the definition of the gazing point is adequate.
