Abstract
The present invention suppresses expansion and contraction of a display image that occur in association with a change in the shape of a lens. 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.
Claims17
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;
- acquisition circuitry that acquires a deviation amount, in which a measurement position on the lens is displaced from a reference position acquired before a change of a shape of the lens, in association with the change in the shape of the lens;
- and
- a temperature sensor;
- wherein
- the acquisition circuitry acquires the deviation amount based on a measurement value provided by the temperature sensor;
- and
- the video data interpolation circuitry prepares the post-interpolation video data based on the deviation amount.
A display apparatus, comprising:
- a display including pixels arranged in a matrix shape, the display apparatus displaying an image based on video data corresponding to respective ones of the pixels;
- a lens which covers a display surface of the display, the lens including a curved surface range in which a surface of the lens is a convex curved surface and the display surface and the lens having different coefficients of thermal expansion;
- 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;
- and
- acquisition circuitry that acquires a deviation amount, in which a measurement position on the lens is displaced from a reference position acquired before a change of a shape of the lens, in association with the change in the shape of the lens;
- wherein
- the video data interpolation circuitry prepares the post-interpolation video data based on the deviation amount.
