抽象的。提出了一种在电子显示设备上显示由计算机准备的多视点图像集的方法。利用该装置，测量了调节反应，并获得了调节反应在焦深范围内和焦深范围外线性变化的结果。相反，在使用立体图像的调节响应的测量中，调节响应在三周每度（cpd）或更小的空间分辨率下在焦深内和焦深外示出线性变化。可以认为对于具有3CPD或更小的空间分辨率的积分摄影的调节响应的测量结果不能用于确定其是否受到整体摄影显示方法或空间分辨率降低的影响。根据这些结果，我们发现，在测量积分摄影的调节响应时，当在焦深范围之外时，空间分辨率需要为3cpd或更高。
Abstract. A method of displaying a multiview image set prepared by a computer on an electronic display device based on integral photography has been formulated. With the device, accommodation response was measured and the result that the accommodation response linearly changed within and outside the range of depth of focus was obtained. In contrast, in the measurement of the accommodation response using the stereoscopic image, the accommodation response showed a linear change within and outside the depth of focus at the spatial resolution of three cycle per degree (cpd) or less. Therefore, it can be considered that the measurement result of the accommodation response for integral photography with a spatial resolution of 3 cpd or less cannot be used to determine whether it is influenced by the integral photography display method or spatial resolution reduction. From these results, we found that spatial resolution is required to be 3 cpd or more when outside of the range of depth of focus in the measurement of the accommodation response for integral photography.
