Stereoscopic view with binocular disparity produces a distorted spatial layout, such as, the puppet theater and cardboard effects. In this paper, we propose a disparity mapping method for reducing the distortion of 3D images. The method is divided into two parts. First, we defined the perceptual model and the modified spatial layout based on this model. Second, the differences in adjacent disparities of the objects were interpolated. We conducted a subjective test to evaluate the proposed method when applied to 3D images taken with a smartphone equipped with a twin-lens camera. There was a significant difference (p < 0.01) between the original 3D images and those of the proposed method. The results of our experiments show that the proposed method makes 3D images more round and gives them a sense of depth.
