作者一直在通过眼动分析图像。为此，有必要将眼动分解为从注视对象接受信息的分量和转移注视点的分量。在前面所考虑的点被称为注视点，这是在本文中定义的基础上的追求眼球运动的属性。5度/秒的眼动速度被用作分离两个分量的阈值。结果，可以将眼睛运动清楚地分离为注视点分量和注视点之间的移位。基于该注视点定义，设计了一种视觉分析仪，可以实时、全面地分析人的眼动。作为视觉分析仪应用的一个实例，分析了VDT图像与通常的动态图像在观看过程中眼动的差异。此外，作为对艺术分析的应用，进行了一项实验，作为分析Sharaku浮世绘的参考材料。实验结果表明，该方法对凝视点的定义是合理的。
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.
