Abstract
We have proposed the retinal projection type super multi-view head mounted display (HMD). The super multi-view method provides stereoscopic information by inducing the accommodation of the human eye by blurring the retinal image. This method uses the principle of Maxwellian view and reconstruct the blur image by overlapping projected each parallax image on the retina. However, considering only the degree of the overlap of the projected parallax images on the retina is not enough for reconstructing the real blur. In order to overcome this problem, we propose the optimal method considering not only the degree of the overlap of the parallax images projected on the retina but also the light intensity of each parallax image to reconstruct the real blur. From the evaluation experiment, we verified that the proposed method improves the reproducibility of blur compared to the method considering only the degree of superimposition of the parallax images projected on the retina. Furthermore, it was also confirmed that the prototype system can display 3D images in the depth range of human ocular accommodation from 200mm to 2000mm. The super multi-view HMD based on the proposed method can induce the accommodation of the human eye with the high reproducibility blur and provide more natural 3D images.
