Outline of Final Research Achievements

In this research, we propose a virtual correction method of eyesight by using a light field display. In order to achieve the method, we construct prototype of a light field display. In addition, we propose calibration method of this display. By using the calibrated display, we propose a light field construction method for virtual correction of eyesight. In addition, we propose a eyesight measuring method since our proposed method requires accurate information of observer's eyesight. In this measuring method, observer observes unique image depending on their eyesight, and then, we can measure the eyesight by confirming which image is observed. Furthermore, we propose virtual eyesight correction using normal displays. In this method, eyesight information is simplified to PSF. By using the PSF, representing images are processed before representation, and then, the observer can observe clear image without glasses. These proposed method can be applied to various kind of representation.
