视觉中的感应场是指视觉刺激源对周边产生影响的电位场。我们测量这个领域如下。我们在感应图形附近显示了一个小光点。当刺激物不能被看到时，记录光的亮度，同时改变亮度。我们创建了一个实验环境，这个过程可以进行基于PC的系统。我们评价了用该系统测量视觉感应场所需的条件。迄今为止，许多研究者认为只有感应图形的轮廓才影响视觉中的感应场。这意味着感应场没有变化，即使图形被填充，即使轮廓宽度改变。我们发现，当图形被填充或轮廓宽度改变时，视觉感应场发生变化。
The induction field in vision means the potential field that represents the effect on the periphery from the source of the visual stimulus. We measured this field as follows. We presented a small spot of light in the neighborhood of the induction figure. The brightness of the light when the stimulus could not be seen was recorded, while the brightness was changed. We created an experiment environment where this procedure could be carried out with a PC-based system. We evaluated the conditions necessary to measure the induction field in vision with this system. Up to now, many researchers have believed that only the contours of an induction figure affect the induction field in vision. This means there are no changes in the induction field, even if the figure is filled, and even if the contour width is changed. We found that the induction field in vision changes, when the figure was filled or the contour width was changed.
