Stereoscopic three‐dimensional (S3D) displays can present a different image to each eye and therefore can convey depth cues and enhance image appearance. However, many people often feel discomfort when the difference between two retinas exceeds a certain amount. There are many factors that affect the visual comfort of S3D displays, and there is no standard for evaluating the visual comfort of 3D contents. In this paper, we conduct an experiment to evaluate the visual discomfort caused by hue asymmetries in 3D images. In particular, it examines how the hue difference factor affects the visual comfort in two types of 3D images: natural images and computer‐generated images. By manipulating the hue asymmetries of 3D images in the CIE LAB color space, the visual comfort was measured subjectively at nine different hue levels. The results of the experiment showed that the visual comfort decreases as the hue difference increases on both image types. We found that natural images are more discomfortable than computer‐generated images at the same hue difference level. It may be due to the fact that natural images have more detailed features. Based on Weber–Fechner's Law, an objective mathematical model was fitted out. The model predicts that the maximum value of hue difference for comfortable watching is about 76.3°. This is a large tolerance range, and it provides the basis for the application that the surface appearance of an object can be simulated easily by using binocular color difference on 3D display devices.

通过立体图像中的色调不对称性评估视觉舒适度

立体三维(S3D)显示器可以为每只眼睛呈现不同的图像,因此可以传达深度提示并增强图像外观。但是,当两个视网膜之间的差异超过一定程度时,许多人通常会感到不适。有许多因素影响S3D显示器的视觉舒适度,并且没有评估3D内容的视觉舒适度的标准。在本文中,我们进行了一项实验,以评估由3D图像中的色调不对称引起的视觉不适。特别是,它检查了色相差异因素如何影响两种3D图像类型的视觉舒适度:自然图像和计算机生成的图像。通过操纵CIE LAB颜色空间中3D图像的色调不对称性,可以在9种不同的色调水平上主观地测量视觉舒适度。实验结果表明,两种图像类型的视觉舒适度都随着色调差异的增加而降低。我们发现,在相同色相差异级别下,自然图像比计算机生成的图像更不舒服。这可能是由于自然图像具有更详细的功能。根据韦伯-费希纳定律,建立了客观的数学模型。该模型预测,舒适观看时的色相差最大值约为76.3°。这是一个很大的公差范围,并且为在3D显示设备上使用双目色差可以轻松模拟对象的表面外观提供了应用基础。我们发现,在相同色相差异级别下,自然图像比计算机生成的图像更不舒服。这可能是由于自然图像具有更详细的功能。根据韦伯-费希纳定律,建立了客观的数学模型。该模型预测,舒适观看时的色相差最大值约为76.3°。这是一个很大的公差范围,并且为在3D显示设备上使用双目色差可以轻松模拟对象的表面外观提供了应用基础。我们发现,在相同色相差异级别下,自然图像比计算机生成的图像更不舒服。这可能是由于自然图像具有更详细的功能。根据韦伯-费希纳定律,建立了客观的数学模型。该模型预测,舒适观看时的色相差最大值约为76.3°。这是一个很大的公差范围,它为应用提供了基础,即可以通过在3D显示设备上使用双目色差轻松地模拟对象的表面外观。该模型预测,舒适观看时的色相差最大值约为76.3°。这是一个很大的公差范围,并且为在3D显示设备上使用双目色差可以轻松模拟对象的表面外观提供了应用基础。该模型预测,舒适观看时的色相差最大值约为76.3°。这是一个很大的公差范围,并且为在3D显示设备上使用双目色差可以轻松模拟对象的表面外观提供了应用基础。
