A display device is equipped with an acquisition unit (50) that acquires a deviation amount by which a measurement position on a lens is displaced due to a change in the lens shape from a reference position before the change of the shape. A video data interpolation unit (51) prepares post-interpolation video data on the basis of the deviation amount. ## Claims ### Claim 1 A display apparatus that includes a display and a lens which covers a display surface of the display, the display including pixels arranged in a matrix shape, the lens including a curved surface range in which a surface of the lens is a convex curved surface, and that displays an image based on video data corresponding to the respective pixels, the display apparatus comprising: video data interpolation circuitry to which original video data are input, the video data interpolation circuitry: prepares interpolation video data having gradations between a gradation of the original video data of pixels which are adjacent to each other, arranges the original video data in order of corresponding pixels, and prepares post-interpolation video data that are the video data corresponding to a number of the pixels and that are selected from the video data in which the original video data are combined with the interpolation video data when the interpolation video data are arranged such that the gradations are continued between the original video data of the corresponding pixels;
