Abstract

There is provided a method of generating corrected image data and a display apparatus which is capable of displaying a pre-corrected image which is corrected in advance, which enables to carry out diopter adjustment for farsightedness due to old age at a practically sufficient level.

In the method of generating corrected image data, the pre-corrected image data consists of amplitude information and phase information, is generated. The display apparatus includes a processing section which generates the pre-corrected image data consists of the amplitude information and the phase information, by a predetermined method of generating corrected image data, and a display section which controls and displays the amplitude information and the phase information of the corrected image data which has been generated.
